Summary: Media Architecture is reaching a level of maturity at which we can identify tools and approaches for addressing the main challenges for HCI practitioners working in this field. While previous influential contributions within Media Architecture have identified challenges for designers and offered case studies of specific approaches, here, we (1) provide guidance on how to tackle the domain-specific challenges of Media Architecture design -- pertaining to the interface, integration, content, context, process, prototyping, and evaluation -- on the basis of the development of numerous installations over the course of seven years, and thorough studies of related work, and (2) present five categories of tools and approaches -- software tools, projection, 3D models, hardware prototyping, and evaluation tools -- developed to address these challenges in practice, exemplified through six concrete examples from real-life cases.

Summary: In this work we present our approach for creating interactive media façades by using purpose-built tools. They are intended to create prototypes and conduct field investigations in this domain. We share our vision of an extended design process which describes ways to engage large user groups by urban prototyping and experience novel interventions in public places. Architects, designers and researchers can receive first hand insights into the suitability of their chosen interaction design concept for media architecture by using our tools and approach.

Summary: There is a well-established culture of early prototyping when designing digital interactive systems, such as paper prototyping and wireframe methods. The culture of designing physical objects is somewhat different: early explorations of form is still prototyped via 2D sketches or renderings, but -- mostly because of the construction effort involved -- prototyping of actual physical objects is deferred to later stages. A problem occurs when designing mixed physical-digital systems, such as tangible user interfaces (TUIs) on interactive surfaces: the high degree of interactivity means that early prototyping is vital, yet there is no viable process for prototyping both the physical and digital aspects simultaneously on a low-fidelity (low-fi) level. Our solution is Paperbox, a toolkit for exploring design ideas for tangible interaction on interactive surfaces. It supports the early exploration of different form factors and immediately provides digital interactivity for the low-fidelity TUI prototypes built with it. We observed our toolkit in use in various settings: as a brainstorming tool by junior designers; in the development of a consumer electronics product in a large industrial company by senior designers; and in a usability study comparing the effect of different levels of fidelity on the outcome. The lessons learnt will enable others to replicate and extend our approach.

Summary: LED based lighting systems have enabled radically new possibilities in the field of artificial lighting. This is due to in part to the LED being digitally controllable which means this efficient light source can also be integrated with sensors and smart environments. This has opened up a new world of lighting and lighting interaction opportunities that has been applied in new concepts in many of the indoor lighting domains. The outdoor lighting domain however has focused mostly on the LED's efficiency and low cost of ownership to save energy and money for local governments. The use of the LED as a potential means for providing interactive city lighting for social good or entertainment is as yet a fairly unexplored area. This is therefore the focus of this workshop to bring together a community of researchers, designers and technologists to explore the potential of interactive city lighting and how it could support or enhance the lives of those living in a city.

Summary: Media façades are one prominent example of how new technologies currently augment urban spaces. At the same time, they offer new, ubiquitous opportunities for novel applications. To achieve a usable and enjoyable outcome, however, designing interaction with media façades demands a structured design process. In this paper, we present our experiences designing iRiS, a system for remote interaction with media façades. We approached the development following a user-centered design approach and addressing the process at two points with additional means: (1) using a purpose-built prototyping toolkit testing and exploring both, content and hardware before deploying the system on the actual façade and (2) experimental use and adaptation of user experience (UX) evaluation methods to investigate the users actions and emotions more holistically in this context.

Summary: LED-based lighting systems have introduced radically new possibilities in the area of artificial lighting. Being physically small the LED can be positioned or embedded into luminaires, materials and even the very fabric of a building or environment. Hundreds of LEDs can be used in a single luminaire or space, of which each could have different light output properties. The light switch therefore in many situations will need to be enhanced or fully replaced by intelligent controls and smart environments that are sensitive to the context and responsive to the people in the environment. The focus of this workshop is to explore new ways of interacting with light where lighting is no longer simply an on or off system, but a flexible system capable of creating a large range of functional, decorative and ambient light effects.

[7] Sketch-a-TUI: low cost prototyping of tangible interactions using cardboard and conductive ink One step beyond / Wiethoff, Alexander / Schneider, Hanna / Rohs, Michael / Butz, Andreas / Greenberg, Saul Proceedings of the 6th International Conference on Tangible and Embedded Interaction 2012 v.9 p.309-312

ACM Digital Library Link

Summary: Graspable tangibles are now being explored on the current generation of capacitive touch surfaces, such as the iPad and the Android tablet. Because the size and form factor is relatively new, early and low fidelity prototyping of these TUIs is crucial in getting the right design. The problem is that it is difficult for the average interaction designer to develop such physical prototypes. They require a substantial amount time and effort to physically model the tangibles, and expertise in electronics to instrument them. Thus prototyping is sometimes handed off to specialists, or is limited to only a few design iterations and alternative designs. Our solution contributes a low fidelity prototyping approach that is time and cost effective, and that requires no electronics knowledge. First, we supply non-specialists with cardboard forms to create tangibles. Second, we have them draw lines on it via conductive ink, which makes their objects recognizable by the capacitive touch screen. They can then apply routine programming to recognize these tangibles and thus iterate over various designs.

Summary: Interactive surfaces form an integral component of intelligent environments. In the paper, we describe HapticArmrest, a simple tactile interface that communicates tactual surface characteristic and form of interactive elements on direct touch surfaces. Spatially separating manual touch input and active tactile output allows for the combination of various types of tactile actuators for versatile haptic feedback. In a preliminary experiment, we indicate that our approach enables a reliable discrimination of virtual elements on touch surfaces solely based on tactile representations. We also assessed the hedonic and pragmatic qualities of the generated tactile stimuli by applying methods from the field of usability research.

ACM Digital Library Link

Summary: Multi-touch screens and surfaces for manipulating digital content play a crucial role in mobile and ubiquitous computing. Augmenting these interactive surfaces with tactile feedback has been found to increase interaction speed, reduce operating errors and minimize visual and cognitive load. Communicating detailed tactile characteristics of virtual elements, however, requires complex electromechanical or electrostatic actuator setups. This increase in complexity makes tactile interfaces intricate, costly or poorly scalable. In order to provide sophisticated tactile sensations with simple actuator technology, we exploit a haptic psychophysical phenomenon called Phantom Sensation. We present a comparison of three standard tactile actuator technologies to see which one can recreate the Phantom Sensation with maximum effect. Our results show the way to a simple and scalable implementation of illusion-based tactile feedback for interactive surfaces. We explore the notion of the Phantom Sensation and its possible applications within a ubicomp scenario.

ACM Digital Library Link

Summary: The increasing number of media facades in urban spaces offers great potential for new forms of interaction especially for collaborative multi-user scenarios. In this paper, we present a way to directly interact with them through live video on mobile devices. We extend the Touch Projector interface to accommodate multiple users by showing individual content on the mobile display that would otherwise clutter the facade's canvas or distract other users. To demonstrate our concept, we built two collaborative multi-user applications: (1) painting on the facade and (2) solving a 15-puzzle. We gathered informal feedback during the ARS Electronica Festival in Linz, Austria and found that our interaction technique is (1) considered easy-to-learn, but (2) may leave users unaware of the actions of others.

Summary: This paper presents SoloFind, a mobile retail experience system for large consumer electronic stores that helps users to retrieve product information. A tangible user interface (TUI) allows customers to collect product information via a simple, Near Field Communication (NFC) based interaction. This data can be customized, reviewed and compared at an interactive kiosk. The simple, touch-like interaction with NFC provides a seamless user experience for customers. This paper focuses on the design of SoloFind, its features and their preliminary evaluation with an experience prototype.

ACM Digital Library Link

Summary: Near Field Communication (NFC) can facilitate mobile interaction with everyday objects, associated digital information and ubiquitous services. Despite the simplicity of the touch-like interaction between mobile devices and tagged physical objects, most people are still unfamiliar with this physical interaction, resulting in various usability problems. In order to improve mobile interaction with NFC-tagged objects, that serve as physical user interfaces (UI), we examine various aspects of their visual design. We identify different phases of mobile interaction with tagged objects and apply a user centered design process to create and evaluate different symbols for these phases. We report on the iterative design of NFC-symbols and physical UIs using low- and high-fidelity prototyping and present the results of a user study which was carried out with an experience prototype for an advertising scenario.
