| Visualizing Human-Environment Interactions: Integrating Concepts and Techniques from HCI, Human Factors and Media Psychology | | BIBAK | Full-Text | 3-12 | |
| Bimal Balakrishnan; Loukas Kalisperis; Danielle Oprean | |||
| As architecture becomes increasingly integrated with information technology,
we need to envision new approaches for architectural visualization. In this
paper, we describe an evolving approach for architectural visualization that
integrates affordable virtual reality tools, motion capture technology and
psychophysiological measurement tools. We start by tracing the development and
validation of our two virtual reality labs. Next, we describe our current
attempts at visualizing embodied interaction and the use of behavioral agents
for simulating human-environment interaction. We conclude by discussing our
current work and future directions, particularly our idea to integrate
psychophysiological tools for measuring cognitive and affective responses to
these information rich environments. Keywords: Architectural visualization; Virtual reality; Motion capture | |||
| Using the GQM Method to Evaluate Calmness in Ubiquitous Applications | | BIBAK | Full-Text | 13-24 | |
| Rainara M. Carvalho; Rossana M. C. Andrade; Káthia M. Oliveira | |||
| Ubiquitous systems change the way users interact with computers, because
their services must be available everywhere at any time, supporting users in
various everyday activities. An essential element for these systems is their
calm interaction with users, which means the system should not disturb them
unnecessarily. Literature currently lacks work focusing on how to evaluate
calmness and case studies made in a real usage situation. The aim of this work
is to propose a model, defined using the Goal-Question-Metric (GQM) method, for
calmness evaluation in ubiquitous systems and to show our results from a case
study with three ubiquitous applications. Keywords: Ubiquitous applications; Calmness; Software measures; GQM | |||
| Distributable Interface Design for Web Applications | | BIBAK | Full-Text | 25-35 | |
| Gianni Fenu; Lucio Davide Spano | |||
| The increasing number of devices available for each person allows to create
unconventional interfaces that coordinate more than one device for supporting
the interaction. In this paper, we introduce a framework for designing
distributable web applications, which supports moving and sharing the different
parts of a user interface across different devices. We depict the architectural
solution and we introduce a set of distribution patterns. In addition, we
describe a concrete application of the framework for a distributable video
player application. Keywords: Distributed interfaces; Web applications; User Interface Engineering;

| The Map as a Tool for Identifying Pervasive Interactions in Today's Home | | BIBAK | Full-Text | 36-48 | |
| Konstantinos Grivas; Stelios Zerefos | |||
| The task of making the spectrum of home network connections visible in its
entirety and details is a necessary first step towards a renewed understanding
of home and domestic life as well as of the technical systems that underpin it.
This paper proposes the categorization of pervasive interactions that take
place in contemporary living spaces through certain criteria and tries to map
them into the predefined spaces of today's home, by creating a basic
visualization tool. The research concludes with an example of a "composite map"
that shows all the interlinked interactions that take place in a contemporary
home. This map can become a potential tool for further research in the fields
of the structure, behaviour and countenance of home networks, of advances in
intimate media, applications and networked devices, and of augmented
architectural spaces that interact with complex and pervasive communication
networks. Keywords: Home mapping; Pervasive computing in architecture; Home automation;

| Makers with a Cause: Fabrication, Reflection and Community Collaboration | | BIBAK | Full-Text | 49-61 | |
| Foad Hamidi; Melanie Baljko | |||
| The potential of using maker and DIY approaches for collaborative learning
is widely recognized. Maker techniques such as rapid prototyping are being
increasingly adopted by schools, universities and colleges in order to
effectively teach core design and science concepts. We describe our approach to
facilitating a series of "MakeShops", maker workshops, for undergraduate
engineering students, in which we used a maker atelier model to facilitate the
design and implementation of self-directed maker projects that combined making
and tinkering with reflection and community collaboration. Keywords: Maker movement; Design facilitation; Pedagogy; Interdisciplinary

| Enabling Programmability of Smart Learning Environments by Teachers | | BIBAK | Full-Text | 62-73 | |
| Asterios Leonidis; Margherita Antona; Constantine Stephanidis | |||
| The evolution of Information Technology (IT) and the emergence of the
Ambient Intelligence paradigm have drastically affected the way users live and
learn. Ambient Intelligence is a vision of the future that offers great
opportunities to enrich everyday activities (e.g., on the road, at home, at
work, etc.) and has been proven to play an important role in education. In
smart learning environments, learning activities are enhanced with the use of
pervasive and mobile computing. This paper presents an extensible software
infrastructure that empowers teachers to design and program purposeful and
engaging learning activities for formal and informal learning environments, by
combining and orchestrating cloud-based, ambient and pervasive facilities and
services. Keywords: Visual programming; End-user development; Ubiquitous environments; Smart

| Co-creation in Context: The User as Co-creator Approach | | BIBAK | Full-Text | 74-84 | |
| Ingrid Mulder; Fenne Van Doorn; Pieter Jan Stappers | |||
| By providing a platform for systemic innovation and co-creative
partnerships, Living Labs open opportunities to get users involved early into
the creative process of new ICT, product and services development. The concept
leaves, however, much room on how to get users actually involved, and does not
explain how to keep users engaged during the entire design process. The current
work elaborates upon the user as co-creator approach and illustrates how
current methods stressing participation and co-creation can be deployed to
strengthen Living Lab practices. We present examples from the ProFit-lab Delft
that demonstrate co-creation in context as well as the user as co-creator
approach. We conclude with a discussion on the results and challenges to
actively co-creating in context. Keywords: Children; Co-creation; Context; Design methods; Empowerment; Living Labs;

| Star(t) to Shine: Unlocking Hidden Talents Through Sharing and Making | | BIBAK | Full-Text | 85-96 | |
| Emilia Louisa Pucci; Ingrid Mulder | |||
| The current article embraces the transformational role digital fabrication
has to empower people doing things previously unthinkable while making it
accessible to a larger audience. Using a research-through-design approach, we
have co-designed a six-step workshop series to activate young adults' hidden
talents through sharing and making. The division in steps was meant to empower
the students gradually and from within their own interests and qualities. The
resulting workshop platform serves as a best practice in learning 21st century
skills, lowering the threshold of access to digital fabrication in education.
The students were active co-creators and obviously learnt new skills. Some
students even had a mind-shifting experience, and demonstrated that it is
indeed possible to transform dropouts into engaged and successful individuals,
who are role models for their peers: "stars shining bright in their local
community". Keywords: 21st century skills; Empowerment; FabLabs; Maker Movement; Transforming

| A Framework for Navigating Human Behavior Through Gameful Digital Rhetoric | | BIBAK | Full-Text | 97-108 | |
| Mizuki Sakamoto; Tatsuo Nakajima | |||
| The use of gameful digital rhetoric presented in this paper becomes a bridge
between the areas of behavior science and cultural studies, and a promising
tool to enhance the real world to enable people to realize human well-being. In
this paper, we propose two models to enhance meaning in the real world based on
the concepts typically used in digital games to assist in the analysis and
design of gameful digital rhetoric. The models offer appropriate abstractions
to enhance the real world with gameful digital rhetoric. We also show results
of experiments to incorporate gameful digital rhetoric in the real world. Keywords: Gameful digital rhetoric; Games; Persuasive technologies; Human well-being | |||
| Evaluating Ubiquitous Computing Environments Using 3D Simulation | | BIBA | Full-Text | 109-118 | |
| Arlindo Santos; Helena Rodrigues | |||
| Human activity is very dynamic and subtle, and most physical environments are also highly dynamic and support a vast range of social practices that do not map directly into any immediate ubiquitous computing functionally. Identifying what is valuable to people is very hard and obviously leads to great uncertainty regarding the type of support needed and the type of resources needed to create such support. We have addressed the issues of system development through the adoption of a Crowdsourced software development model [13]. We have designed and developed Anywhere places, an open and flexible system support infrastructure for Ubiquitous Computing that is based on a balanced combination between global services and applications and situated devices. Evaluation, however, is still an open problem. The characteristics of ubiquitous computing environments make their evaluation very complex: there are no globally accepted metrics and it is very difficult to evaluate large-scale and long-term environments in real contexts. In this paper, we describe a first proposal of an hybrid 3D simulated prototype of Anywhere places that combines simulated and real components to generate a mixed reality which can be used to assess the envisaged ubiquitous computing environments [17]. | |||
| The Transformative Potential of Making in Teacher Education: A Case Study on Teacher Training Through Making and Prototyping | | BIBAK | Full-Text | 119-128 | |
| Susanna Tesconi; Lucía Arias | |||
| The paper describes an ongoing research on teacher education for the
implementation of making and digital fabrication in educational settings taking
part at LABoral Art Centre, Spain. It aims to define key points and indications
for the design of learning environments for teachers through making and
prototyping in the context of an art centre as an open education lab. We
present a qualitative instrumental case study articulated around two
dimensions: the analysis of the context of the art centre, and the design of
two teaching education programs. The analysis of LABoral context aims to
explore the potentiality of an open lab and its related community as a learning
environment for teacher education. The study of the teaching education programs
is set to define the principles in order to put forward a proposal for the
design of a learning environment for teacher education in making. Keywords: Making; Teacher training; Prototyping; Empowerment; Art; Design | |||

| Ghada Al-Hudhud; Noha Alrajhi; Nouf Alonaizy; Aysha Al-Mahmoud; Latifah Almazrou; Dalal bin Muribah | |||
| Many people in their work environment are interested and focused on their work, and they do not want to interrupt their work progress by doing simple office tasks like Increasing or decreasing the light brightness in the office or the temperature of the office. In addition, a more important issue is to consider cases where some of people have major disabilities in their bodies that prevent them from doing that. In this situation, Brain Signals for Smart Offices (BSSO) is considered to be a preferable solution. | |||
| Developing and Evaluating Two Gestural-Based Virtual Environment Navigation Methods for Large Displays | | BIBAK | Full-Text | 141-151 | |
| Paulo Dias; João Parracho; João Cardoso; Beatriz Quintino Ferreira; Carlos Ferreira; Beatriz Sousa Santos | |||
| In this paper we present two methods to navigate in virtual environments
displayed in a large display using gestures detected by a depth sensor. We
describe the rationale behind the development of these methods and a user study
to compare their usability performed with the collaboration of 17 participants.
The results suggest the users have a better performance and prefer one of them,
while considering both as suitable and natural navigation methods. Keywords: Navigation in virtual environments; Gestural interaction; 3DUIs | |||

| Giannis Drossis; Antonios Ntelidakis; Dimitris Grammenos; Xenophon Zabulis; Constantine Stephanidis | |||
| This paper reports on the design and implementation of BeThereNow, a public
interactive information system where users are depicted immersed in various
sceneries. The work is focused on the domain of info-tainment in public spaces
using large displays and aims on short-time usage. The implemented system
employs a mixed reality application through which users are informed about
different sceneries and also create personalized digital postcards. This
process is accomplished using computer vision algorithms in order to depict
users and objects, while removing the background of the scene. Finally, the
lessons learned from the long-term deployment of the system out-in-the-wild are
presented, providing an insight on the users' actions and reactions and
feedback on future research directions. Keywords: Large scale displays; Interactive public spaces; Immersive user experience;

| A Gesture Recognition Method for Proximity-Sensing Surfaces in Smart Environments | | BIBAK | Full-Text | 163-173 | |
| Biying Fu; Tobias Grosse-Puppendahl; Arjan Kuijper | |||
| In order to ease the daily activities in life, a growing number of
sophisticated embedded systems is integrated into a users environment. People
are in need to communicate with the machines embedded in the surroundings via
interfaces which should be as natural as possible. A very natural way of
interaction can be implemented via gestures. Gestures should be intuitive, easy
to interpret and to learn. In this paper, we propose a method for in-the-air
gesture recognition within smart environments. The algorithm used to determine
the performed gesture is based on dynamic time warping. We apply 12 capacitive
proximity sensors as sensing area to collect gestures. The hand positions
within a gesture are converted into features which will be matched with dynamic
time warping. The gesture carried out above the sensing area are interpreted in
realtime. Gestures supported can be used to control various applications like
entertainment systems or other home automation systems. Keywords: Gesture recognition; Dynamic time warping; Capacitive proximity sensing | |||
| Developing Intuitive Gestures for Spatial Interaction with Large Public Displays | | BIBAK | Full-Text | 174-181 | |
| Yubo Kou; Yong Ming Kow; Kelvin Cheng | |||
| Freehand gestures used in gestural-based interactive systems are often
designed around technical limitations of gesture capturing technologies,
resulting in gestures that may not be intuitive to users. In this paper, we
investigated freehand gestures that are intuitive to users with common
technical knowledge. We conducted a gesture solicitation study with 30
participants, who were asked to complete 21 tasks on a large display using
freehand gestures. All gestures in the study were video-recorded. We conducted
in-depth interviews with each participant to ask about the gestures they had
chosen and why they had chosen them. We found that a large proportion of
intuitive freehand gestures had metaphoric origins from daily uses of
two-dimensional surface displays, such as smart phones and tablets. However,
participants may develop new gestures, particularly when objects they are
manipulating deviated from those commonly seen in surface technologies. In this
paper, we discuss when and why participants developed new gestures rather than
reusing gestures of similar tasks on two-dimension surface displays. We suggest
design implications for gestures for large public displays. Keywords: Large displays; Gestures; Freehand; Spatial interaction | |||
| AR Coloring Jigsaw Puzzles with Texture Extraction and Auto-UV Mapping Algorithm | | BIBAK | Full-Text | 182-187 | |
| Youngho Lee | |||
| There have been many applications with AR technology such as advertisement,
education, etc. Books with AR technology are the most interesting application
area. In this paper, we propose an AR coloring jigsaw puzzles which provides
users with puzzle pieces for coloring and AR/VR worlds for colored 3D
animations. The proposed puzzle is composed of a jigsaw puzzle with unpainted
pieces and a smart phone application. The jigsaw puzzle with unpainted pieces
is designed large pieces of puzzle and several uncolored pieces. The smart
phone application has an AR scene for extracting color from puzzle and a VR
world for user interaction with colored animals. Keywords: Augmented reality; Virtual reality; Coloring book; Vuforia SDK | |||
| Smart Kiosk with Gait-Based Continuous Authentication | | BIBAK | Full-Text | 188-200 | |
| Duong-Tien Phan; Nhan Nguyen-Trong Dam; Minh-Phuc Nguyen; Minh-Triet Tran; Toan-Thinh Truong | |||
| The authors propose to develop a smart kiosk that plays the role of an
identity selector activated implicitly when a user is approaching that kiosk.
The identity of a user is recognized implicitly in background by a
mobile/wearable device based on his or her gait features. Upon arriving at a
smart kiosk, the authentication process is performed automatically with the
current available user identity in his or her portable device. To realize our
system, we propose a new secure authentication scheme compatible with
gait-based continuous authentication that can resist against known attacks,
including three-factor attacks. Furthermore, we also propose a method to
recognize users from their moving patterns using multiple SVM classifiers.
Experiments with a dataset with 38 people show that this method can achieve the
accuracy up to 92.028%. Keywords: Gait-based recognition; Continuous authentication; Smart kiosk; Mobile

| Gesture-Based Configuration of Location Information in Smart Environments with Visual Feedback | | BIBAK | Full-Text | 201-211 | |
| Carsten Stocklöw; Martin Majewski | |||
| The location of objects and devices in a smart environment is a very
important piece of information to enable advanced and sophisticated use cases
for interaction and for supporting the user in daily activities and emergency
situations. To acquire this information, we propose a semi-automatic approach
to configure the location, size, and orientation of objects in the environment
together with their semantic meaning. This configuration is typically done with
graphical user interfaces showing either a list of objects or a representation
of objects in form of 2D or 3D virtual representations.
However, there is a gap between the real physical world and the abstract virtual representation that needs to be bridged by the user himself. Therefore, we propose a visual feedback directly in the physical world using a robotic laser pointing system. Keywords: Smart environments; Configuration; Personalization | |||
| Subjective User Experience and Performance with Active Tangibles on a Tabletop Interface | | BIBAK | Full-Text | 212-223 | |
| Jan B. F. van Erp; Alexander Toet; Koos Meijer; Joris Janssen; Arnoud de Jong | |||
| We developed active tangibles (Sensators) that can be used in combination
with multitouch tabletops and that can provide multisensory (visual, auditory,
and vibrotactile) feedback. For spatial alignment and rotation tasks we
measured subjective user experience and objective performance with these
Sensators. We found that active feedback increased accuracy in both tasks, for
all feedback modalities. Active visual feedback yielded the highest overall
subjective user experience and preference scores. Our contribution is that
active feedback improves subjectively perceived performance and reduces
perceived mental workload. Additionally, our findings indicate that users
prefer to be guided by visual signs over auditory and vibrotactile signs. Keywords: Tangible interfaces; User experience; Tabletop; Multimodal; Active feedback | |||
| Auditory Browsing Interface of Ambient and Parallel Sound Expression for Supporting One-to-many Communication | | BIBAK | Full-Text | 224-233 | |
| Tomoko Yonezawa | |||
| In this paper, we introduce an auditory browsing system for supporting
one-to-many communication in parallel with an ongoing discourse, lecture, or
presentation. The live reactions of audiences should reflect the main speech
from the viewpoint of active participation. In order to browse numerous live
comments from audiences, the speaker stretches her/his neck toward a particular
section of the virtual audience group. We adopt the metaphor of "looking
inside" toward the direction of the seating position with repositioned and
overlaid audiences' voices corresponding to the length of the voice regardless
of the seating of real audiences. As a result, the speaker could browse the
comments of the audience and show the communicative behaviors when she/he was
interested in a particular group of the audience's utterances. Keywords: Auditory space; One-to-many parallel communication; Browsing interface;

| Immersiveness of Ubiquitous Computing Environments Prototypes: A Case Study | | BIBAK | Full-Text | 237-248 | |
| Tiago Abade; José C. Campos; Rui Moreira; Carlos C. L. Silva; José Luís Silva | |||
| The development of ubiquitous computing (ubicomp) environments raises
several challenges in terms of their evaluation. Ubicomp virtual reality
prototyping tools enable users to experience the system to be developed and are
of great help to face those challenges, as they support developers in assessing
the consequences of a design decision in the early phases of development. Given
the situated nature of ubicomp environments, a particular issue to consider is
the level of realism provided by the prototypes. This work presents a case
study where two ubicomp prototypes, featuring different levels of immersion
(desktop-based versus CAVE-based), were developed and compared. The goal was to
determine the cost/benefits relation of both solutions, which provided better
user experience results, and whether or not simpler solutions provide the same
user experience results as more elaborate one. Keywords: Ubiquitous computing; Virtual environments; Prototyping; Evaluation;

| Employing Virtual Humans for Interaction, Assistance and Information Provision in Ambient Intelligence Environments | | BIBAK | Full-Text | 249-261 | |
| Chryssi Birliraki; Dimitris Grammenos; Constantine Stephanidis | |||
| This paper reports on the design, development and evaluation of a framework
which implements virtual humans for information provision. The framework can be
used to create interactive multimedia information visualizations (e.g., images,
text, audio, videos, 3D models) and provides a dynamic data modeling mechanism
for storage and retrieval and implements communication through multimodal
interaction techniques. The interaction may involve human-to-agent,
agent-to-environment or agent-to-agent communication. The framework supports
alternative roles for the virtual agents who may act as assistants for existing
systems, standalone "applications" or even as integral parts of emerging smart
environments. Finally, an evaluation study was conducted with the participation
of 10 people to study the developed system in terms of usability and
effectiveness, when it is employed as an assisting mechanism for another
application. The evaluation results were highly positive and promising,
confirming the system's usability and encouraging further research in this
area. Keywords: Virtual humans; Virtual agents; Virtual assistants; Embodied agents;

| From Collaborative Scenario Recording to Smart Room Assistance Models | | BIBAK | Full-Text | 262-273 | |
| Gregor Buchholz; Peter Forbrig | |||
| There is still much to be done in implementing assistance systems for
Intelligent Environments. Different approaches exist that aim at providing the
user with useful and pleasant functionality. One group of methods uses
behavioral models to derive supportive actions from the observation by sensors.
This is a promising approach but creating such models is a laborious and
error-prone task. Examples of the behavior of persons in intelligent
environments and their interactions with the devices are a starting point for
the (partial) generation of such models. In this paper we present an approach
to record user behavior without the need of real users performing in the real
environment. As a special thematic priority we will focus on the preparation
phase of collaborative scenario recording and the used notation. Additionally,
the paper will explain the generation of models from the recorded traces. Keywords: Intelligent environments; Ubiquitous computing; Task models | |||
| Hierarchical Narrowcasting | | BIBA | Full-Text | 274-286 | |
| Michael Cohen | |||
| Narrowcasting, in analogy to uni-, broad-, and multicasting, is a formalization of media control functions that can be used to adjust exposure and receptiveness. Its idioms have been deployed in spatial sound diffusion interfaces, internet telephony, immersive chatspaces, and collaborative music audition systems. Here, we consider its application to desk-top music composition systems, using Pure Data ("Pd"), a dataflow language for audio and multimedia, to develop a proof-of-concept. A hierarchical model of a drum kit is deployed, applying narrowcasting at various levels of aggregation to drum machine sequences. These ideas can also be extended to audio augmented reality situations. | |||
| Development of a User-Oriented IoT Middleware Architecture Based on Users' Context Data | | BIBAK | Full-Text | 287-295 | |
| Taehyun Ha; Sangwon Lee; Narae Kim | |||
| How to manage the connections of things efficiently with heterogeneous
things is one of the important issues for IoT middleware development. Many
researches have been focused on this issue but still no one accepted as the
common model in the IoT environment. In this sense, we aim to develop a new IoT
middleware architecture containing simple key-value model based and no-model
based context-awareness function. The suggested middleware represents the
context data without strictly defined data structure. Rather, it processes the
context more focusing on the other technical aspects. We build the middleware
architecture based on the basic structure of GSN (Global Sensor Networks).
Also, by adapting no-model based context representation method suggested by
Habit, we added the context-awareness function to the GSN. Through the
middleware, many heterogeneous things not integrated on the standard structure
can be managed effectively. We expect the suggested middleware can provide a
flexible solution in current IoT development situation. Keywords: IoT middleware architecture; GSN; Context-awareness | |||
| Measuring the Arrangement of Multiple Information Devices by Observing Their User's Face | | BIBAK | Full-Text | 296-304 | |
| Saori Kikutani; Koh Kakusho; Takeshi Okadome; Masaaki Iiyama; Satoshi Nishiguchi | |||
| We propose to measure the 3D arrangement of multiple portable information
devices operated by a single user from his/her facial images captured by the
cameras installed on those devices. Since it becomes quite usual for us to use
multiple information devices at the same time, previous works have proposed
various styles of cooperation among the devices for data transmission and so
on. Other previous works propose to coordinate the screens so that they share
the role of displaying contents larger than each screen. Those previous works
obtain the 2D tiled arrangement of the screens by detecting their contacts with
each other using sensing hardware equipped on their edges. Our method estimates
the arrangement among the devices in various 3D positions and orientations in
relation to the user's face from its appearance in the image captured by the
camera on each device. Keywords: Multiple portable devices; Device coordination; Screen arrangement; Facial

| SpreadView: A Multi-touch Based Multiple Contents Visualization Method Composed of Aligned Layers | | BIBAK | Full-Text | 305-316 | |
| Joong Ho Lee; Hyoyoung Kim; Ji-Hyung Park | |||
| There have been many studies concerning development of large scalable
interactive displays employing multi-touch interfaces, which is rapidly
replacing conventional static methods of presenting information to the public.
Interactive large displays are used in various fields, such as in the education
sector as interactive whiteboards, way-finding screens in retail and hospital
environments and so on. We propose the SpreadView, a new method for displaying
digital contents on public large display, which generates pages corresponding
to the traditional content files included in the traditional folder in PC, and
generates an information display layer including a folder display portion
corresponding to the traditional folder and giving output the aligned
information display layers. The SpreadView senses multi-touch events to change
an output format of the information display layer according to various user
manipulation patterns such as one point touch or one point drag on a page, two
point touches or pinch on a page, multiple touches on multiple pages in the
information. Through these various touch manipulations the SpreadView rearrange
information display so as to correspond the user's expectations. The SpreadView
may provide a design motivation to improve the usability in manipulating big
amount of digital contents under the other forms of computing environment such
as tabletop computing, virtual reality and augmented reality. Keywords: Multi-touch; Interactive large display; Contents visualization | |||
| Bandage Man: A Spatial Interaction Design in a Sensible Space for Connecting Family | | BIBAK | Full-Text | 317-324 | |

| The alienation between family members is mainly caused by the descendant's
work and study, which causes that the elderly live in the countryside lonely
and cannot be actually concerned and cared by the descendants. Gradually, the
relation between family members is alienated. In this paper, the life
information of the elderly is recorded with sensing network through furniture.
The physical object on the child end can receive the emotional information of
the elderly. Through the interaction mode of feeling transmission between the
sensing network and Bandage Man, it is to synchronize the inter-generational
family affection contact, so as to increase the interaction opportunity between
family members and form a feeling concern network between families. Keywords: Elderly living alone; Feeling network; Man-machine interaction; Family

| Learning Instead of Markers: Flexible Recognition of Mobile Devices on Interactive Surfaces | | BIBAK | Full-Text | 325-336 | |
| Philipp Mock; Jörg Edelmann; Wolfgang Rosenstiel | |||
| We propose an approach for recognition of mobile devices on interactive
surfaces that do not support optical markers. Our system only requires an axis
aligned bounding box of the object placed on the touchscreen in combination
with position data from the mobile devices integrated inertia measurement unit
(IMU). We put special emphasis on maximum flexibility in terms of compatibility
with varying multi-touch sensor techniques and different kinds of mobile
devices. A new device can be added to the system with a short training phase,
during which the device is moved across the interactive surface. A device model
is automatically created from the recorded data using support vector machines.
Different devices of the same size are identified by analyzing their IMU data
streams for transitions into a horizontally resting state. The system has been
tested in a museum environment. Keywords: Human computer interaction; Tabletop interaction; Markerless object

| GlassNage: Layout Recognition for Dynamic Content Retrieval in Multi-Section Digital Signage | | BIBAK | Full-Text | 337-348 | |
| Adiyan Mujibiya | |||
| We report our approach to support dynamic content transfer from publicly
available large display digital signage to users' private display, specifically
Glass-like wearable devices. We aim to address issues concerning dynamic
multimedia signage where the content are divided into several sections. This
type of signage has become increasingly popular due to optimal content
exposures. In contrast to prior research, our approach excludes computer vision
based object recognition, and instead took an approach to identify how contents
are being laid-out in a digital signage. We incorporate techniques to recognize
basic layout features including corners, lines, edges, and line segments; which
are obtained from the camera frame taken by the user using their own device.
Consequently, these layout features are combined to generate signage layout
map, which is then compared to pre-learned layout map for position detection
and perspective correction using homography estimation. To grab a specific
content, users are able to choose a section within the captured layout using
the device's interface, which in turn creates a request to contents server to
send respective content information based on a timestamp and a unique section
ID. In this paper, we describe implementation details, report user study
results, and conclude with discussion of our experiences in implementation as
well as highlighting future work. Keywords: Digital signage; Public display; Public-to-private; Multi section; Layout

| Naoya Okada; Jun Imura; Takuji Narumi; Tomohiro Tanikawa; Michitaka Hirose | |||
| In this research, we propose the design of a sustainable on-site past-scene
experience system applied in a public location using personal mobile user
devices. Through our system, to experience an AR exhibition, users simply
download an AR application onto their personal mobile device. By superimposing
a past-scene image of an actual site onto the present scene, users can
appreciate the past scene on-site through their own device without the need for
any special AR device or support staff. We held both attended and unattended
on-site exhibitions to evaluate the social acceptableness and effectiveness of
the proposed unattended exhibition system. The results show that, using the
personal mobile devices of the users, the proposed system is deemed socially
acceptable, and that our unattended exhibition system can evoke and maintain
user interest as much as an attended exhibition. In addition, we have been
distributing this system as an iPad/iPhone application through the Internet,
and the number of users is continuously increasing, thereby proving the
sustainability of our proposed exhibition system. Keywords: Augmented reality; Digital museum; Mobile device; Public exhibition | |||
| Enhancing Facial Impression for Video Conference | | BIBAK | Full-Text | 362-369 | |
| Sungyeon Park; Heeseung Choi; Ig-Jae Kim | |||
| Most people have their preferred impression to be seen by others. Our face
warping method can make this real. In this paper, we propose a new technique
for automatic transformation of facial impression, for example, look more
attractive or baby-face from the original. We build an impression score
function, trained by scores from human raters, and the function is used to get
displacement vectors for a given face. To preserve the facial identity as much
as possible, we constrain the facial deformation range with facial
classification. In case of real time application, such as video conference,
there are frequent facial expressions variation and position changes. Face
tracker is used to cope with this changing situation. Through our experiments,
our proposed method can be one of the promising methods for future video

| Natural interaction refers to people interacting with technology as they are
used to interact with the real world in everyday life, through gestures,
expressions, movements, etc., and discovering the world by looking around and
manipulating physical objects [16]. In the domain of cultural heritage research
has been conducted in a number of directions including (a) Personalised
Information in Museums, (b) Interactive Exhibits, (c) Interactive Games
Installations in Museums, (d) Museum Mobile Applications, (e) Museums presence
on the Web and (f) Museum Social Applications. Most museums target family
groups and organize family-oriented events in their programs but how families
choose to visit particular museums in response to their leisure needs has
rarely been highlighted. This work exploits the possibility of extending the
usage of AmI technology, and thus the user experience, within leisure spaces
provided by museums such as cafeterias. The Museum Coffee Table is an augmented
physical surface where physical objects can be used for accessing information
about artists and their creations. At the same entertainment for children is
facilitated through the integration of popular games on the surface. As a
result, the entire family can seat around the table, drink coffee and complete
their visit to the museum acquiring additional knowledge and playing games. Keywords: Ambient intelligence; Tabletop interaction; Augmented reality; Cultural

| Nowadays an increasingly wide variety of multimedia devices can be networked
together in ever-growing smart environments. Although these networks, thanks to
mobile technology and Wi-Fi, are almost ubiquitous by now, the players therein
are still working largely distinct from one another. To simply play a file on
the playback device A, which is originally housed on device B, is therefore a
complicated task, despite the theoretical possibility provided by existing
networking. Especially playing and viewing files on multimedia devices under
various circumstances and limited reproduction capabilities is a non-trivial
problem. Current solutions from industry still put little interoperable
approaches in proprietary systems. Individual multimedia devices of the same
manufacturer can be combined intelligently, but with respect to the usability
the system scales poorly, the (also physical) distribution increases the
difficulty of access to the functions and control is largely independent of the
user's context. In this work, a solution is developed, which focuses in
particular on the context-based playback of files: sending video, music, image
and text files to output devices with different display options, as well as the
distribution of these multimedia files between devices. Activities are centered
on a mobile device for visualizing the spatial distribution of all devices,
including the user's position and the intuitive movement of files of various
types between them. Keywords: Image processing and computer vision; Enhancement; Filtering | |||
| The Capacitive Chair | | BIBAK | Full-Text | 397-407 | |
| Andreas Braun; Sebastian Frank; Reiner Wichert | |||
| Modern office work often consists of spending long hours in a sitting
position. This can cause a number of health-related issues, including chronic
back pain. Ergonomic sitting requires suitably adjusted chairs and switching
through a variety of different sitting positions throughout the day. Smart
furniture can support this positive behavior, by recognizing poses and
activities and giving suitable feedback to the occupant. In this work we
present the Capacitive Chair. A number of capacitive proximity sensors are
integrated into a regular office chair and can sense various physiological
parameters, ranging from pose to activity levels or breathing rate recognition.
We discuss a suitable sensor layouts and processing methods that enable
detecting activity levels, posture and breathing rate. The system is evaluated
in two user studies that test the activity recognition throughout a work week
and the recognition rate of different poses. Keywords: Capacitive proximity sensor; Posture recognition; Smart furniture | |||

| We present the architecture of an Advanced Driver Assistance System (ADAS)
based on common dual camera smartphones, emphasizing on the calibration
procedure which is active during the initialization phase (prior to the actual
driving). NAVIEYES project attempts to make use of the video information
received from both the front and the rear cameras of the phone in order to
infer and alert drivers upon potential dangerous situations. This study focuses
on the information received from the front camera. 10 different mobile devices
were tested, in order to choose the most powerful and ergonomic platform. A
calibration experiment is carried by 22 subjects, and the first version of the
application is tested using a driving simulator. The system is deployed on a
real car, and several warning paradigms such as audio, video and mixed alerts
are also analyzed. We present the HCI questionnaire, analyze the data and
propose further developments. Keywords: Personal navigation assistant; Smartphone; Dual camera; Driver assistant;

| We describe Paper Controller, a paper based controller that allows users to
design and create their own task specific controllers with touch-sensing
capability for controlling a desktop computer. Casual users of computers can
design and create a task specific Paper Controller by printing and/or drawing
buttons freely with conductive ink and by drawing annotations including text
and figures with regular ink. We implemented a prototype system for the Paper
Controller. The system consists of the Paper Controller, a Clipboard for the
Paper Controller, and a parameterization software running on a computer. We
conducted an experiment to examine whether users can create a Paper Controller.
The results show that the users can create and use their own Paper Controllers. Keywords: Paper controller; Prototyping; Conductive ink; Capacitive sensing | |||

| Combining Generative Art and Physiological Information for New Situation of Garden Restaurant | | BIBAK | Full-Text | 449-460 | |
| Tung-Chen Tsai; Chao-Ming Wang | |||
| Restaurant consumers often spend most of their time queuing outside garden
restaurants during mealtimes, waiting for a table. If restaurant owners and
customers can effectively utilize these idle times, both of them will
inevitably benefit. This study developed an interactive device that can be used
to divert customers' attention during waiting times and enable them to enjoy
the fun of using this device, thereby helping restaurant owners promote their
garden restaurants and local postcards.
A literature review on human-computer interaction, wearable devices, and generative art was conducted to propose the design principle of the interactive device. Subsequently, prototyping, user manual, and recommendations for users were developed, and the effectiveness of the prototype was assessed. This study developed an interactive device with which users can use during their waiting or idling time. The prototype of this interactive device involves combining the concept of generative art and a pulse sensor. Participants can use the garden restaurant's postcard as an interactive media, which can then be converted into images through image processing. According to rules and motion of a graphics, the prototype can provide unique visual feedback. In addition, the proposed prototype entails a wearable pulse sensor that enhances the graphic rules and motions, enabling users to see their own heartbeat information. Moreover, a novel interactive thinking for wearable devices was proposed. The contributions of this study included (1) completing the prototyping of a pulse sensor based on the concept of generative arts, and (2) developing a novel wearable interactive device that can be used in garden restaurants.

| Design of Co-evolving Textiles Applied to Smart Products | | BIBAK | Full-Text | 461-470 | |
| Rachel Zuanon; Geraldo Coelho Lima Júnior | |||
| Among the main barriers to the production of smart textiles on an industrial
scale, there are the difficulty of integration of electronic and textile raw
materials; the maintenance of textiles, especially with regard to their
washing; and the poor durability of smart capabilities associated with the
textile structure. Moreover, most breakthroughs in the development of smart
textiles occur in a limited way and targeted to meet the specific features of
the project or wearable product. This article proposes the hypothesis of
co-evolving smart textile as a contribution to overcome these problems.
Memorization and customization features are viable due to nanotechnology and
assigned to the textile basis. These characteristics aim to contribute to the
progress in the design and production process of smart textiles in large scale,
aimed at daily use, and able to co-evolve with the user's body and the
surrounding environment. Keywords: Textile design; Smart textile; Co-evolving smart textile; Smart products | |||
| User Location Modeling Based on Heterogeneous Data Sources | | BIBAK | Full-Text | 473-484 | |
| Patrick Gottschaemmer; Tobias Grosse-Puppendahl; Arjan Kuijper | |||
| Over the past decade, interest in home automation systems constantly grew.
This yields especially for daily life -- considering the connection of
intelligent everyday devices through the Internet of Things. To allow automatic
actions on these devices, user localization systems have become a major input
modality for smart home systems. The location of a user (or rather a subject)
can be determined by different localization techniques, such as sensitive floor
systems, discrete activity sensors like light switches or RSSI-based
WLAN/Bluetooth beacons (e.g. smartphones). These heterogeneous data sources
provide various means of user location certainty, the ability to identify a
user or the ability to recognize multiple subjects in the same location. In
order to achieve a higher grade of accuracy, multiple data sources can be
combined by location fusioning algorithms. However, to allow the integration of
such algorithms on a hardware independent basis, a common user location model
is needed, which can represent all important aspects of these localization
techniques. This paper investigates the concepts of existing user localization
systems and develops a new model to represent the location of subjects based on
already existing location models. An implementation is provided based on
Eclipse SmartHome, an open-source building automation framework. Keywords: Location modeling; User location; Location fusion | |||
| Monitoring Wildlife in Contaminated Environments via the Carrier Pigeon-Like Sensing System | | BIBA | Full-Text | 485-495 | |
| Hill Hiroki Kobayashi; Hiromi Kudo; Kaoru Sezaki | |||
| This paper presents a Carrier Pigeon-like Sensing System (CPSS), a future-present archetype that will enable the observation of inaccessible and contaminated environments, such as the area surrounding the Fukushima Daiichi nuclear power plant. Our system employs wildlife-borne sensing devices with Animal- Touch'n Go (ATG) and animal-to-animal Internet sharing capabilities; such devices expand the size of monitoring areas where electricity and information infrastructures are limited or nonexistent. Through our approach, monitoring information can be collected from remote areas safely and cost-effectively. Based on the human-computer-biosphere interaction (HCBI) concept, CPSS is presented in this paper, with an overview of the concept, methods employed, and current work in progress. We provide a clear scope for CPSS in the context of natural ecosystems. Furthermore, we implement a documentation framework that describes how complex interactions between living organisms within such natural ecosystems are connected with HCI. | |||

| Festivals and big scale events are becoming more and more popular, they can attract thousands of spectators. Ensuring the safety of the crowd has become a top priority to many organisers after the multitude of dramatic accidents that resulted in losses in human lives. Monitoring the crowd via smartphones is a relatively new technique that emerged recently with the capabilities of mobile phones to transmit their GPS location data. We present a novel approach, based on the local crowd pressure, combined with the detection of groups in a crowd, to detect critical situations and propose evacuation plans that does not separate groups of people that are together. Groups were detected using DBSCAN clustering algorithm with 80% accuracy. Location acquisition was tested during the Campus Fever event, and 87% of the collected data had an accuracy lower than 10 m while 29% of the total data had 5 m of accuracy. During 2 h of monitoring, activity of the application, reduced the battery of 20%. | |||
| Indirect Monitoring of Cared Person by Onomatopoeic Text of Environmental Sound and User's Physical State | | BIBA | Full-Text | 506-517 | |
| Yusuke Naka; Naoto Yoshida; Tomoko Yonezawa | |||
| In this paper, we propose a nonverbal, descriptive method for creating daily life logs, in text format, on behalf of people who require monitoring and/or assistance in taking care of themselves. The users environmental situations are converted into and recorded as onomatopoeic texts in order to preserve their privacy. The users ambient context is detected by the accelerometer, gyro sensor, and microphone in her/his smart device. We propose a soft monitoring system that utilizes nonverbal expressions of both onomatopoeic text logs and symbolic sound expressions that is named Soundgram. We have investigated impressions regarding the monitoring of the elderly and the proposed system via a questionnaire distributed to two groups of potential users, the elderly and middle-aged people, which captures the viewpoint of both the recipient and the caregiver. | |||
| Estimating Positions of Students in a Classroom from Camera Images Captured by the Lecturer's PC | | BIBAK | Full-Text | 518-526 | |
| Junki Nishikawa; Koh Kakusho; Masaaki Iiyama; Satoshi Nishiguchi; Masayuki Murakami | |||
| We propose to estimate the position of each student in a classroom by
observing the classroom with a camera attached on the notebook or tablet PC of
the lecturer. The position of each student in the classroom is useful to keep
observing his/her learning behavior as well as taking attendance, continuously
during the lecture. Although there are many previous works on estimating
positions of humans from camera images in the field of computer vision, the
arrangement of humans in a classroom is quite different from usual scenes.
Since students in a classroom sit on closely-spaced seats, they appear with
many overlaps among their regions in camera images. To cope with this
difficulty, we keep observing students to capture their faces once they appear,
and recover the positions in the classroom with the geometric constraint that
requires those positions to be distributed on the same plane parallel to the
floor. Keywords: Classroom; Position estimation; Student positions; Continuous observation | |||
| Activity Context Integration in Mobile Computing Environments | | BIBAK | Full-Text | 527-535 | |

| In this paper, we propose an approach of activity context integration as a
means of evaluating semantic information, by integrating situational
information from heterogeneous sensors in a smartphone. The proposed activity
context integration is a method to provide a foundation for interacting with
situation-aware mobile computing systems. Moreover, we develop a context-aware
embedded middleware that generates high-level integrated contexts through the
fusion of internal * external sensors in a smartphone. The proposed system
extracts semantic information such as the user's activities. Keywords: Activity recognition; Context integration; Embedded middleware | |||

| The issue of loss or kidnapping children has become unfortunately a
widespread phenomenon in many countries. To address this issue, this paper
presents a children tracking system. It consists of a small device carried by
the child and a mobile application that enables the user to track his child
movements by tracking that device. That will be done by using GPS and Bluetooth
4.0 technology to track children in indoor and outdoor locations. For indoor,
the application searches for the child by detecting the beacon device using
Bluetooth 4.0. And for the outdoor locations, the application uses the GPS/GPRS
chip. Keywords: GPS/GPRS; Bluetooth 4.0; Beacon | |||
| Spending Precious Travel Time More Wisely: A Service Model that Provides Instant Travel Assistance Using Input from Locals | | BIBAK | Full-Text | 557-567 | |
| Kenro Aihara; Susumu Kono; Shizuhiro Sugino | |||
| We propose a new service model that incorporates input from locals to
provide instant travel assistance.
No matter how well travelers plan, circumstances at their destination invariably force them to modify their plans, especially towards the end of a tour. However, it is difficult for travelers to get useful information or support. Accordingly, we propose a service model whereby on-site travelers can instantly access planning suggestions from locals. Travelers send a personalized plan request with conditions such as desired end point (destination and time), preferences (e.g. dining, historical spots, etc.), and group information. The service delivers this to participating locals, who create appropriate plans and register them with the service. We conducted a preliminary survey of the model in March, 2014 in Matsuyama, Japan. Despite an insufficient volume of data the questionnaire results support our approach. Locals provided useful information that was perceived as more credible than online search results.

| Interpreting Food-Venue Visits: Spatial and Social Contexts of Mobile Consumption in Urban Spaces | | BIBAK | Full-Text | 568-577 | |
| Shin'ichi Konomi; Kenta Shoji; Tomoyo Sasao | |||
| The increasing amount of mobility data introduces an opportunity to develop
novel urban applications that are integrated with everyday practices. Although
simple events (e.g., visits to places) can be inferred from mobility traces,
events have very different meanings in different contexts. To contribute to the
body of work that aims to uncover effective methods to integrate ubiquitous
computing technologies in urban spaces and context, we discuss interpretation
of ubiquitous events in urban computing: food-venue visits. Based on a survey
and a small supplemental study, we identify the spatial and social contexts
that influence the meanings of food-venue visits. We also suggest a possibility
of novel technological support for eating out. Keywords: Eating out; Food; Consumption; Urban context | |||

| Antonio Opromolla; Valentina Volpi; Andrea Ingrosso; Carlo Maria Medaglia | |||
| In a "smart" city context, citizens' participation allows to create public
services and products meeting the real people's needs. In this regard, the
co-design process is a useful practice for encouraging city users to co-create
new effective solutions. However, it is fundamental to renovate methodologies
and tools for citizens' engagement. In this paper, we argue that the
gamification approach could increase the willingness of city users in getting
involved in Public Administration (PA) decision-making processes and in
co-design practices. Assuming that, we present the main findings of a survey
conducted to investigate city users' behaviours and needs on gamification and
co-design issues. These findings will be useful to identify the most suitable
applications combining these two practices. Keywords: Co-design; Gamification; Game design; Survey; Smart city; Decision-making

mobile devices to collect public comments and local information. However, it is
difficult to cope with diminishing civic engagement due to the loss of diverse
outdoor activities in towns using existing civic engagement platforms. In this
paper we present Activity Recipe, a framework for supporting citizens to create

outdoor activities. We discuss the methods to 'spread' effective activities for
local communities and cultivate citizens' awareness for these activities based
on Activity Recipe. Keywords: Activity recipe; Mobile phones; Civic engagement; Community development;

| Personalized Energy Reduction Cyber-physical System (PERCS): A Gamified End-User Platform for Energy Efficiency and Demand Response | | BIBAK | Full-Text | 602-613 | |
| Nicole D. Sintov; Michael D. Orosz; P. Wesley Schultz | |||
| The mission of the Personalized Energy Reduction Cyber-physical System
(PERCS) is to create new possibilities for improving building operating
efficiency, enhancing grid reliability, avoiding costly power interruptions,
and mitigating greenhouse gas emissions. PERCS proposes to achieve these
outcomes by engaging building occupants as partners in a user-centered smart
service platform. Using a non-intrusive load monitoring approach, PERCS uses a
single sensing point in each home to capture smart electric meter data in real
time. The household energy signal is disaggregated into individual load
signatures of common appliances (e.g., air conditioners), yielding near
real-time appliance-level energy information. Users interact with PERCS via a
mobile phone platform that provides household- and appliance-level energy
feedback, tailored recommendations, and a competitive game tied to energy use
and behavioral changes. PERCS challenges traditional energy management
approaches by directly engaging occupant as key elements in a technological
system. Keywords: Games; Gamification; Psychology; Energy efficiency; Human factors;

| Consumer Concerns About Smart Meters | | BIBAK | Full-Text | 625-635 | |
| Rani Yesudas; Roger Clarke | |||
| Modernisation of the grid is inevitable as aging and outdated traditional
power infrastructure is subject to challenges of cost, climate change,
distributed power generation, and unstable demand patterns. Engineers
identified smart meters as a vital element for modernisation and hastily
implemented and deployed them without fully considering their implications.
There has been significant consumer concern, and rollouts in various countries
have been delayed and even stopped entirely. The resistance from consumers
makes it evident that their requirements were inadequately addressed. A major
reason for this is that the requirements elicitation process was seriously
deficient. This article first analyses the functionalities of a smart metering
system from a consumer perspective and discusses the risks to consumer assets
that are perceived to, and in some cases do, arise from the introduction of
smart meters. It then proposes that proponents of smart meter schemes need to
improve their risk assessment and requirements elicitation processes, in order
to better understand user realities, needs and concerns and ensure that their
designs address them effectively. Keywords: Consumer perspective; Risk; Smart meters; Consumer concerns; Consumer

| Despite the physiological and psychological benefits of humour on health,
many health applications for aging hold very little humour. We investigate the
potential of humour in health for aging, reviewing studies from humour therapy.
To show the potential of humour in this domain, we look at the functions of
humour and discuss their application to the design of virtual agents. Then, we
propose new conceptual designs based on the therapeutic use of humour: agents
as comic relief, agent as comic partners, and agents as virtual clowns. We aim
to initiate a new research agenda in this domain and stimulate further
investigations in the use of humour-mediated technology. Keywords: Humour; Virtual health agent; Therapeutic agent; Aging; Seniors | |||

| Humor Techniques: From Real World and Game Environments to Smart Environments | | BIBAK | Full-Text | 659-670 | |
| Anton Nijholt | |||
| In this paper we explore how future smart environments can be given a sense
of humor. Humor requires smartness. Entering witty remarks in a conversation
requires understanding of the conversation, the conversational partner, the
context and the history of the conversation. We can try to model interaction
smartness and how to use it in creating not only witty remarks, but also to
create humorous events. Smart sensors and actuators, embedded in our
environments and our wearables allow us to make changes to a digitally enhanced
physical environment. Witty remarks in language can have their counterpart in
witty events in digital environments, including social media environments with
their own communication characteristics. Sequential and parallel juxtapositions
of incongruous and contrasting events invade our communication and, in
addition, can be expected to emerge or to be created in digitally enhanced
physical environments too, accidentally and intentionally. Keywords: Incongruity humor; Computational humor; Intended humor; Accidental humor;

| The paper explores the very basis of linguistic theories of humor with a
view of applying them to computational humor. Computation requires tighter
definitions. The paper analyzes joke-carrying texts based on the existing
script-based methods. It compares jokes that have the same setup but different
punchlines by examining the background knowledge that should be available to
detect humor. It then moves into jokes where the same joke text elicits
different responses from the reader, and conjectures that the responses are
based on the readers' world knowledge and preferences. Such responses make it
possible not only to analyze humor, but also to understand more about the
people that produce the responses. Keywords: Humor; Computational detection of humor; Semantics; Knowledge-based humor

| Twitter: The Best of Bot Worlds for Automated Wit | | BIBAK | Full-Text | 689-699 | |
| Tony Veale; Alessandro Valitutti; Guofu Li | |||
| Language affords a great many opportunities for the intelligent reuse of
linguistic content. Rather than always putting our own thoughts into our own
words, we often convey feelings through the words of others, by citing,
quoting, mimicking, borrowing, varying or ironically echoing what others have
already said. Social networking platforms such as Twitter elevate linguistic
reuse into an integral norm of digital interaction. On such platforms, who you
follow and what you re-tweet can say as much about you as the clothes you wear
or the art you hang on your walls. But not everyone that is worth following is
human, and not everything that is worth re-tweeting was first coined by a real
person. More and more of the witty and thought-provoking content on Twitter is
generated by bots, artificial systems that write their own material and vie for
our attention just as humans do. Real people knowingly follow artificial bots
for reasons that are subtle and diverse, but a significant reason is surely
Twitter itself. This paper explores Twitter as a smart environment for
automated wit, and describes the mechanics of a wittily inventive new
Twitterbot named @MetaphorMagnet. Keywords: Twitter; Twitterbot; Metaphor; Reuse; Irony; Social networks; Wit | |||
