Multitouch sensing for collaborative interactive walls

Abstract

In this paper we explain the design of t-Frame, a hardware/software architecture that allows the implementation of multiuser interactive wall. t-Frame brings multi-touch sensing to a generic display by means of low cost digital video cameras. The design of t-Frame is illustrated in detail, together with a prototype installation. We show how t-Frame differs from other approaches and discuss our findings, together with a plan of future research and improvements. © 2008 Springer Science+Business Media, LLC.
