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)
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 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)
This paper presents a new text-entry approach based on the 10-finger-system 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)
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)
Current Augmented Reality navigation applications for pedestrians usually do not visualize tracking errors. However, tracking uncertainties can accumulate so that the user is presented with a distorted impression of navigation accuracy. To increase the awareness of users about potential imperfections of the tracking at a given time, we alter the(More)
This paper presents a new text-entry approach for multitouch 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)
This game aims to present a modern approach for interaction between multiple devices, such as a large screen tablet and a smartphone, using the example of a simple game like tower defense. The player interacts with the game on the tablet by using simple touch input and on the smartphone by using Augmented Reality and gestures. The position of the smartphone(More)
We present a Capture the Flag based game that investigates the possible engagements in a multi-device game. The distinction between a publicly used space and a player's private space is made and utilized to display different information to players. The tablet and the Augmented Reality component are used to see how players can be drawn to a certain physical(More)
