CA 1189163
Abstract A tactile sensing system is provided which consists of essentially four components including a touch surface having a plurality of mechanically and electrically isolated sensitive sites, transducer means associated with each of the sensitive sites for converting a mechanical response to an electrical signal, first signal processing means for scanning the signals produced by the transducer means and converting such signals to digital format, and second signal processing means including a computer for interpreting and displaying the data. The system of this invention is capable of providing high contrast, high normal load resolution, moderate spatial resolution and high sensitivity to determine such mechanical contact parameters as presence, pressure, pressure pattern, texture, hardness and topography of an object contacting the touch surface. In addition, separate means are included enabling the system to detect the location, magnitude and direction of shear forces applied to the touch surface.
