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,…
Multi-touch Table
This multi-touch table I built as a research platform is based on a diffused illumination approach: 91x57cm surface (107cm diagonal, 16:10 aspect ratio) Toshiba TDP‐EW25 projector (1280x800px) Point Grey Firefly MV camera (640x480px, 60fps) with wide-angle lense Infrared illumination (850nm)…
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…
FTIR Compliant Surface Tutorial
Inspired by a post on NUI Group Community Forums by Tinkerman I decided to give FTIR (to be accurate, a combination of DSI and FTIR.) a try, creating my first owncompliant surface. The described technique of applying a layer of silicone to…
