This paper explores the design of a reconfigurable large-area high-resolution pressure sensing floor to help study human dance movement. By measuring the pressure of a user interacting with the system, our device is able to provide real-time knowledge about both the location of the performer on the floor as well as the amount and distribution of force being exerted on the floor. This system has been designed to closely integrate and synchronize with external systems including marker-based motion capture systems, audio-sensing equipment and video-sensing technology, thus allowing for robust multimodal sensing of a subject in the integrated environment. Furthermore, the mats comprising the floor can be readily re-arranged in order to allow for a large number of configurations. Some other possible applications of the pressure sensing floor include virtual reality based entertainment systems or video game control interfaces as well as rehabilitation projects for disabled people with foot ...
