Apparatus, system and methods for collecting position information over a large surface using electrical field sensing devices

摘要

An apparatus, system and methods are provided for collecting information on the geographic positions of several moving or immobile objects simultaneously. A plurality of large scale printed circuits having charge transfer capacitance sensing properties are linked by a communication network in order to form a coherent sensing surface for the collection and reconnaissance of positioning and movement information. The positioning and movement information gathered can be used as input information by media control systems.
