IdWristbands for User Identification on Multi-touch Surfaces

Prototype of IdWristband

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 blinking pattern to determine the orientation of the wristband in order to reliably associate corresponding …

HandsDown and IdLenses

Unregistered and registered user

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, content, or functionality of the user interface. To identify, users put down their hand flat on the …

Multiuser-aware Surface Computing

Hand contour extraction steps

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 user identification respectively discrimination, for interactive surfaces. Of course, there is DiamondTouch which can distinguish …

PhoneTouch

PhoneTouch Logo

PhoneTouch is a novel technique for integration of mobile phones and interactive surfaces. The technique enables use of phones to select targets on the surface by direct touch, facilitating for instance pick&drop-style transfer of objects between phone and surface. The technique is based on separate detection of phone touch events by the surface, which determines …
