Great Affordance for Large Interactive Spaces Kickables are tangibles that users manipulate with their feet. While they maintain the affordance of traditional tangibles, kickables scale to arbitrarily large spaces as kickables reside on the ground. This affordance makes kickables well-suited for…

Personal Clipboards
Personal Clipboards for Individual Copy-and-Paste on Shared Multi-User Surfaces The copy-and-paste functionalities provided by clipboards are omnipresent on today’s computing devices from desktops to tablets to mobile phones. Despite this success, clipboards did not make their way to multi-user surfaces…
GravitySpace
A New Approach to Tracking People and Objects Based on a Pressure-Sensing Floor GravitySpace is a new approach to tracking people and objects indoors. Unlike traditional solutions based on cameras, GravitySpace reconstructs scene data from a pressure-sensing floor. While the floor…
PICOntrol
In everyday environments, we are increasingly surrounded by a growing number of electric devices. At the same time, many of these devices are shrinking in physical size. Both developments come along with their own challenges when it comes to controlling…
IdWristbands for User Identification on Multi-touch Surfaces
IdWristbands are designed to enable user identification for camera-based multi-touch surfaces. In this approach, users wear wristbands equipped with infrared LEDs, to provide touches with identities. The LEDs transmit coded light pulses as an identifier. We are using a specific…
HandsDown and IdLenses
Biometric User Identification for Multi-touch Surfaces Based on Hand Contours HandsDown is a novel technique for user identification on interactive surfaces. It enables users to access personal data on a shared surface, to associate objects with their identity, and to fluidly customize appearance,…
Conducting a Virtual Orchestra
In the context of my Diploma thesis I developed new means of input for an existent system allowing users with any skill to conduct a virtual orchestra in realtime. The eWatch, a wearable computing and sensing platform, was selected as…
Indirect Multi-touch Interaction
Most current multi-touch devices use direct input, especially larger surfaces. In this context, we asked how much the advantages of multi-touch depend on the directness of input. An indirect multi-touch device has several potential advantages, such as interaction from a…
Multiuser-aware Surface Computing
The above video shows a working prototype which allows users to identify by simply putting down their hands on the surface. This is related to a topic I became recently more and more interested in: the topic of multiuser-awareness, or…
