It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

We present a wireless prototype system for real-time snowboard training. This system can be used to detect common mistakes during snowboarding and to give students immediate feedback on how to correct their mistakes. The project illustrates new ways to assist students during sports training and to enhance their learning experience on the slope.

Borchers, Jan O. (2008): HCI@aachen: experiments in the future of media and mobility. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3633-3638.
This paper presents the Media Computing Group at RWTH Aachen University and its goal to explore the future of collaborative, ubiquitous interaction with audiovisual media. It explains how this initial research vision has led to work on the levels of HCI theory, algorithms, toolkits, testbeds, and design patterns. It also introduces some of our external collaborations, in particular the Excellence Initiative, Germany's most fundamental change in government research funding to date, which supports RWTH and our group.

Herkenrath, Gero, Karrer, Thorsten and Borchers, Jan O. (2008): Twend: twisting and bending as new interaction gesture in mobile devices. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3819-3824.
In this work we present a hardware prototype that uses bending gestures as input for a mobile device and experimental setups that compare possible gestures with other, more traditional input methods in mobile computing. These will eventually result in guidelines for researchers and designers how to build bendable devices and show new interaction metaphors for computer user interfaces.

Ballagas, Rafael, Memon, Faraz, Reiners, Rene and Borchers, Jan O. (2007): iStuff mobile: rapidly prototyping new mobile phone interfaces for ubiquitous computing. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1107-1116.
iStuff Mobile is the first rapid prototyping framework that helps explore new sensor-based interfaces with existing mobile phones. It focuses on sensor-enhanced physical interfaces for ubiquitous computing scenarios. The framework includes sensor network platforms, mobile phone software, and a proven rapid prototyping framework. Interaction designers can use iStuff Mobile to quickly create and test functional prototypes of novel interfaces without making internal hardware or software modifications to the handset. A visual programming paradigm provides a low threshold for prototyping activities: the system is not difficult to learn. At the same time, the range of examples built using the toolkit demonstrates a high ceiling for prototyping activities: the toolkit places few limits on prototype complexity. A user study shows that the visual programming metaphor enables prototypes to be built faster and encourages more iterations than a previous approach.

Lee, Eric, Wolf, Marius and Borchers, Jan O. (2005): Improving orchestral conducting systems in public spaces: examining the temporal characteristics and conceptual models of conducting gestures. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 731-740.
Designing interactive conducting exhibits for public spaces poses unique challenges, primarily because the conceptual model of conducting music varies amongst users. In a user study, we compared how conductors and non-conductors place their beats when conducting to a fixed orchestral recording of Radetzky March, and found significant differences between these two groups. Conductors lead the actual music beat with their gestures by an average of 150 ms, compared to 50 ms for non-conductors; non-conductors also vary their placement of the beat 50% more than conductors. Furthermore, we found differences in how users conceptually mapped their gestures to the music, such as conducting to the musical rhythm rather than to the beat. We are incorporating these results into an upcoming conducting system for public spaces to increase its usability; we believe they also apply to a more general class of musical gestures such as dance.

Personal Orchestra is the first system to let users conduct an actual audio
and video recording of an orchestra, using an infrared baton to control tempo,
volume, and instrument sections. A gesture recognition algorithm interprets
user input, and a novel high-fidelity playback algorithm renders audio and
video data at variable speed without time-stretching artifacts. The system is
installed as a public exhibit in the HOUSE OF MUSIC VIENNA.

Borchers, Jan O. (2000): A Pattern Approach to Interaction Design. In: Proceedings of DIS00: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 2000. pp. 369-378.
To create successful interactive systems, user interface designers need to cooperate with developers and application domain experts in an interdisciplinary team. These groups, however, usually miss a common terminology to exchange ideas, opinions, and values. This paper presents an approach that uses pattern languages to capture this knowledge in software development, HCI, and the application domain. A formal, domain-independent definition of design patterns allows for computer support without sacrificing readability, and pattern use is integrated into the usability engineering life cycle. As an example, experience from building an award-winning interactive music exhibit was turned into a pattern language, which was then used to inform follow-up projects and support HCI education.
