Summary: Successfully conveying the interactivity of a Public Information Display
(PID) can be the difference between a display that is used or not used by its
audience. In this paper, we present an interactive PID called 'Cruiser Ribbon'
that targets pedestrian traffic. We outline our interactive PID installation,
the visual cues used to alert people of the display's interactivity, the
interaction mechanisms with which people can interact with the display, and our
approach to presenting rich content that is hierarchical in nature and thus
navigable along multiple dimensions. This is followed by a field study on the
effectiveness of different mechanisms to convey display interactivity.
Results from this work show that users are significantly more likely to
notice an interactive display when a dynamic skeletal representation of the
user is combined with a visual spotlight effect (+8% more users) or a follow-me
effect (+7% more users), compared to just the dynamic skeletal representation.
Observation also suggests that -- at least for interactive PIDs -- the dynamic
skeletal representation may be distracting users away from interacting with a
display's actual content, and that individual interactivity cues are affected
by group size.

Summary: A key challenge for creating large interactive displays in public spaces is
in the definition of ways for the user to interact that are effective and easy
to learn. This paper presents the outcomes of user evaluation sessions designed
to test a series of different gestures for people interacting with large
displays in the public space. It is an initial step towards the broader goal of
establishing a natural means for immersive interactions. The paper proposes a
set of simple gestures for the execution of the basic actions of selecting and
rearranging items in a large-scale dashboard. We performed a comparative
analysis of the gestures, leading to a more in-depth understanding of the
nature of spatial interaction between people and large public displays. More
specifically, the analysis focuses on the scenarios when the interaction is
restricted to an individual's own body, without any further assistance from
associated devices. The findings converge into the elaboration of a model for
assisting with the applicability of spatial gestures in response to both the
context and the content they are applied to.

Summary: The tabletop computer interface has the potential to support idea generation
by a group using the brainstorming technique. This paper describes the design
and implementation of a table-top brainstorming system. To gain insights into
its effectiveness, we conducted a user study which compared our system against
a more conventional approach. We analysed the processes and results with the
goal of gaining an understanding of the ways a tabletop brainstorming system
can support the phases of this activity. We found that our tabletop interface
facilitated the creation of more ideas and participants tended to create more
categories. We observed that the tabletop provides a useful record of the group
processes and this is valuable for reviewing how well a group followed
recommended brainstorming processes. Our contributions are a new table-top
brainstorming system and insights into the nature of the benefits a tabletop
affords for brainstorming and for capturing the processes employed by a group.

Summary: Tabletops have the potential to provide new ways to support collaborative
learning generally and, more specifically, to aid people in learning to
collaborate more effectively. To achieve this potential, we need to gain
understanding of how to design tabletop environments so that they capture
relevant information about collaboration processes so that we can make it
available in a form that is useful for learners, their teachers and
facilitators. This paper draws upon research in computer supported
collaborative learning to establish a set of principles for the design of a
tabletop learning system. We then show how these have been used to design our
Collaid (Collaborative Learning Aid) environment. Key features of this system
are: capture of multi-modal data about collaboration in a tabletop activity
using a microphone array and a depth sensor; integration of these data with
other parts of the learning system; transforming the data into visualisations
depicting the processes that occurred during the collaboration at the table;
and sequence mining of the interaction logs. The main contributions of this
paper are: our design guidelines to build the Collaid environment and the
demonstration of its use in a collaborative concept mapping learning tool
applying data mining and visualisations of collaboration.

Summary: New forms of natural user interfaces, particularly tabletops, are now a
possibility due to the staggering advances in sensing and display technology.
There is an immediate need for corresponding progress on the foundational
software for exploiting the potential of these new hardware products. This
requires research into natural and effective gestural interaction, with careful
consideration of the core facilities needed for effective and consistent use.
At the same time, an exploration of real-world tabletop applications will
provide a basis for studying and advancing the core functionality.
In this video, we illustrate several aspects of our ongoing research on
interactive surfaces. This includes studying the core functionality of
tabletops, such as gestures and interaction primitives, file access,
application switching, transfer of information between devices, and user
modeling for personalisation. These core functions have been used as the
foundation for a number of real-world deployed applications. The key
contributions of this work are the novel primitives for tabletops interaction
as well as the applications that have been created by building upon them.

Summary: In all but the purest appliance interfaces, users need some of the
fundamental core facilities for general computing interface elements: to change
applications; change the files the application uses; and control which
interface elements are present on the table. While these facilities have been
refined for desktops, the particular affordances and limitations of tabletops
call for a rethink of the interfaces for these actions. We describe the design
process for Switch, which supports the core functions of application and
configuration switching at an interactive tabletop. We began with several
low-fidelity prototypes, evaluating these to a refined set of four. We then
evaluated each of these using Heuristic Evaluation with 4 experts and Cognitive
Walkthrough by 5 experts. From this, we created the final Switch design which
we evaluated for usability with a think-aloud study by 8 users. We conclude
that Switch is easy to learn and use for the core facilities for general
computing. We reflect on lessons learnt and directions for the future. Our key
contributions are the exploration of user interface support for a set of the
most fundamental core facilities for general computing at tabletops, our use of
these to design the Switch tool and our usability evaluation of Switch,
providing a foundation for the design of the core user interface elements that
will enable people to make flexible use of tabletops.

Summary: Interactive tabletops show great potential to be used in learning contexts,
particularly in museums, as a way for people to collaboratively learn and
explore rich sets of digital information. However, it is a real challenge for
exhibition designers, or Curators, to create exhibitions for tabletop displays,
as it is tedious to create these data-sets manually. Curator is a
cross-platform tool that can be used by non-technical designers and museum
staff to construct rich information collections for exploration on our
interactive tabletop. After the data-set has been constructed using Curator on
a desktop computer, this information can be tested and displayed on the
tabletop immediately, providing an engaging, collaborative experience for
exploration and learning.

Summary: This paper explores the nature of interfaces to support people in accessing
their files at tabletop displays embedded in the environment. To do this, we
designed a study comparing people's interaction with two very different classes
of file system access interface: Focus, explicitly designed for tabletops, and
the familiar hierarchical Windows Explorer. In our within-subjects
double-crossover study, participants collaborated on 4 planning tasks. Based on
video, logs, questionnaires and interviews, we conclude that both classes of
interface have a place. Notably, Focus contributed to improved collaboration
and more efficient use of the workspace than with Explorer. Our results inform
a set of recommendations for future interfaces enabling this important class of
interaction -- supporting access to files for collaboration at tabletop devices
embedded in an ubicomp environment.

Summary: Tabletop interfaces provide a new medium for collocated collaboration.
Consequently, tabletops need to support access to file systems, just as a core
facility of conventional computer systems is to provide an interface to a file
system. However, the constraints of tabletop interfaces call for rethinking
standard approaches to file system interaction. This paper presents the design
of OnTop, a novel associative-search approach to file system interaction: users
navigate multiple file systems by selecting focus files, retrieving similar
ones. We report a small-scale qualitative evaluation of OnTop against a more
conventional file browser approach: OnTop was consistently preferred and found
to be more efficient, especially for larger file collections.

Summary: Tutorial dialogues can be analyzed as an interaction in which a tutor
"debugs" a student's knowledge representation by diagnosing and correcting
conceptual misunderstandings. In this paper, we outline some tentative steps
toward a theory which describes tutorial interactions. We outline the goal
structure of a tutor, describe types of conceptual bugs that students have in
their understanding of physical processes and discuss some of the
representational viewpoints necessary to diagnose and correct these bugs.
