Touch screen device facilitating estimation of entity orientation and identity

Abstract:

Devices, systems, computer-implemented methods, and computer program products that can facilitate estimating orientation and/or identity of an entity that touches a touch screen device are provided. According to an embodiment, a device can comprise a pixelated touch screen that provides a two-dimensional capacitance map in response to detection of one or more entities touching the pixelated touch screen. Capacitance data of the two-dimensional capacitance map is inversely proportional to a distance between fingers of the one or more entities and the pixelated touch screen. The device can further comprise a processor that applies an analytic method to the two-dimensional capacitance map to estimate orientation or identity of the one or more entities.
