Abstract

A tactile sensory system comprising a floor covering integrated with a tactile sensory layer to form a tactile sensory surface is described. The tactile sensory layer has a plurality of sensors. The system also comprises a controller connected to the tactile sensory surface to track a person or object. In one embodiment, the tactile sensory surface is flexible and is manufactured in bulk on a roll, so that it is adjustable in both length and width. Any type of sensors can be used, including pressure sensors, force sensors, force and position-sensing resistors, proximity sensors, and so forth.
