As more interactive surfaces enter public life, casual interactions from passersby are bound to increase. Most of these users can be expected to carry a mobile phone or PDA, which nowadays offers significant computing capabilities of its own. This offers new possibilities for interaction between these users' private displays and large public ones. In this(More)
Digital games are increasingly profiting from sensing technologies. However, their focus is mostly on sensing limb movements. We propose that sensing capabilities could also be used to engage players with proxemics: the interpersonal distance between players. We further add that wireless networks offer complementary distance zones for designers, offering(More)
This poster abstract describes the seamless integration of uninstrumented mobile devices into an interactive surface environment. By combining a depth camera with a RGB camera for tracking, we are able to identify uninstrumented mobile devices using visual marker tracking. We describe the technical details of combining the two cameras and an example(More)
We present a simple solution for a touch detection system on any display at a very low cost. By using a Microsoft Kinect, we can detect fingers and objects on and above a display. We conducted a user study in order to evaluate the accuracy of this system compared to the accuracy of a capacitive touch monitor. The results show, that the system can't compete(More)
This paper focuses on the coupling of mobile hand-helds with a stationary multi-touch table top device for collabora-tive purposes. For different fields of application, such as the health care domain, the coupling of these two technologies is promising. For the example of sudoku puzzles we evaluated the collaboration between multi-touch table top devices(More)
The increased attention which multitouch interfaces have received in recent years is partly due to the availability of cheap sensing hardware such as FTIR-based screens. However, this method has so far required a bulky projector-camera setup behind the screen. In this paper, we present a new approach to FTIR sensing by "inverting" the setup and placing the(More)

However, tracking(More)
This paper presents a new text-entry approach based on the 10-finger-system 1 for multi-touch devices. A unique finger gesture-to-key mapping system is developed to overcome the lack of tactile feedback on touchscreens. The missing tactile feedback is in fact the main reason behind the low performance of virtual touchscreen keyboards with soft buttons. For(More)
This paper presents a new text-entry approach for multi-touch devices based on both the 10-finger-system and a unique gesture-to-key mapping to overcome the lack of tactile feedback on touchscreens. We use unique gestures for all 10 fingers based on the QWERTY layout. There are two classes of gestures: Taps and Slidings. Taps activate the keyboards central(More)
