Claim 0:
1. A contactless touchscreen interface comprising:
a digital display to display digital information;
a proximity detector comprising a plurality of image sensors located adjacent an edge of the digital display to detect user interaction at a virtual touch intersection plane offset a distance from the digital display and to resolve the interaction into XY offset-plane interaction coordinates with reference to the digital display;
a gaze determining imaging system comprising an image sensor which determines a gaze relative offset with respect to the digital display using facial image data captured by the image sensor;
an interface controller comprising a parallax adjustment controller to convert the XY offset-plane interaction coordinates to XY on-screen apparent coordinates using the gaze relative offset and the distance; and
an input controller to generate an input at the XY on-screen apparent coordinates wherein the plurality of image sensors of the proximity detector comprise first and second image sensors configured to separately ascertain respective opposite regions of the digital display.
