Kickables: Tangibles for Feet

This example of a museum exhibit on basic molecules allows visitors to interact by kicking physical objects around—which we call kickables. (a) This visitor starts a tutorial video by pushing a kickable from pause to play. (b) Another visitor scrubs through a different video. (c) This visitor assembles a water molecule by moving a red hydrogen atom towards a blue oxygen atom.

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 large-scale walk-up installations, such as tradeshows or museum exhibits, as illustrated by our prototype installation …

Personal Clipboards

Subarea Clipboards (HandsDown)

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 until now, because most surface computing devices cannot distinguish input from different users. To them, …

GravitySpace

We use a mirror-metaphor to show how GravitySpace identifies users and tracks their location and poses

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 is limited to sensing objects in direct contact with the ground, GravitySpace reconstructs contents above …

Handheld projector, projected interface consisting of on and off buttons, and target devices (lamps)

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 these devices. On the one hand, a plethora of devices imply that not all of …

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 …

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 …
