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, …

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 …

.NET/C# TUIO Server

There only seems to be a C++ implementation of the TUIO server, not a C# version yet. I quickly looked into writing a C# wrapper, but it seemed to be rather complicated. Using Bespoke’s Open Sound Control (OSC) library, I started implementing my own C# TUIO server. It is still quite limited (only support external TUIO cursors …
