Contact sensing and interaction techniques for a distributed, multimodal floor display

This paper presents a novel interface and set of techniques enabling users to interact via the feet with augmented floor surfaces. The interface consists of an array of instrumented floor tiles distributed over an area of several square meters. Intrinsic force sensing is used to capture foot-floor contact at resolutions as fine as 1 cm, for use with floor-based multimodal touch surface interfaces. We present the results of a preliminary evaluation of the usability of such a display.
