1. A touch discrimination system comprising:
a touch-enabled display; multiple imaging devices embedded within a surrounding border of the touch-enabled display, each imaging device including a fisheye lens providing a hemispherical field of view with a diameter substantially aligned and coplanar with a surface of the touch-enabled display; a memory resource to store instructions; and one or more processors using the instructions stored in the memory resource to:
detect a plurality of simultaneous touch inputs on the surface of the touch-enabled display performed by a plurality of operating users;obtain image data from the multiple imaging devices for each of the plurality of simultaneous touch inputs, the image data simultaneously depicting, in the hemispherical fields of view, (i) a hand or finger in contact with the surface of the touch-enabled display corresponding to each of the plurality of simultaneous touch inputs, and (ii) a portion of a body corresponding to the hand or finger, wherein the portion of the body is outside a perimeter of the touch-enabled display;associate each hand or finger in contact with the surface of the touch-enabled display with one of the plurality of simultaneous touch inputs, wherein each association is determined using only the image data and the plurality of simultaneous touch inputs; andidentify a user of the plurality of operating users who made each of the plurality of simultaneous touch inputs based on the portion of the body outside the perimeter of the touch-enabled display that corresponds to each hand or finger associated with each of the plurality of simultaneous touch inputs, wherein each user is identified by analyzing the image data without any other sensor data. |
