Multi-touch interaction with computationally enhanced surfaces has received considerable recent attention. Approaches to the implementation of multi-touch interaction such as Frustrated Total Internal Reflection (FTIR) and Diffused Illumination (DI) have allowed for the low cost development of such surfaces, leading to a number of technology and application(More)
Multi-touch interaction with computationally enhanced surfaces has received considerable attention in recent years. Hardware implementations of multitouch interaction such as Frustrated Total Internal Reflection (FTIR) and Diffused Illumination (DI) have allowed for the low cost development of surfaces. Although many of these technologies and associated(More)
Interactive tabletops and surfaces (ITSs) provide rich opportunities for data visualization and analysis and consequently are used increasingly in such settings. A research agenda of some of the most pressing challenges related to visualization on ITSs emerged from discussions with researchers and practitioners in human-computer interaction,(More)
We present SleeD, a touch-sensitive Sleeve Display that facilitates interaction with multi-touch display walls. Large vertical displays allow multiple users to interact effectively with complex data but are inherently public. Also, they generally cannot present an interface adapted to the individual user. The combination with an arm-mounted, interactive(More)
A large body of work asserts that interactive tabletops are well suited for group work, and numerous studies have examined these devices in educational contexts. However, few of the described systems support simulations for collaborative learning, and none of them explicitly address immersion. We present SimMed, a system allowing medical students to(More)
We present initial results of SimMed, an ongoing interdisciplinary project for the use of interactive tables in medical education. The project is motivated by the need of combining theoretical knowledge with practice in medical education and the time-consuming task of finding appropriate patients for teaching. Students in medicine are able to interact(More)
The geographical domain was often used as a showcase to show the possibilities of multi-touch interaction. Nonetheless, researchers have rarely investigated multi-user interaction with GIS - in fact, most of the geographical tabletop applications are not suited to multi-user interaction. Our multitouch application, GlobalData, allows multiple people to(More)
Research on interactive wall displays has thus far focused mostly on professional use. However, as large displays with support for touch and other input modalities become more common, it becomes reasonable to assume use in more casual settings as well. We present Miners, one of the first collaborative games for a touch-sensitive display wall, and(More)
We present YouTouch!, a system that tracks users in front of an interactive display wall and associates touches with users. With their large size, display walls are inherently suitable for multi-user interaction. However, current touch recognition technology does not distinguish between users, making it hard to provide personalized user interfaces or access(More)
We present SimMed, a novel tool for medical education that allows medical students to diagnose and treat a simulated patient in real-time. The students assume the roles of doctors, collaborating as they interact with the patient. To achieve immersion and support complex interactions for gaining procedural knowledge, the hybrid user interface combines(More)
