Abstract
An interactive display system configured for detecting an object or user input provided with an object. The system includes a display surface on which graphic images are displayed, one or more scanning light sources configured for scanning the interactive display surface, and a light detector configured for detecting light reflected from an object that is adjacent to or in contact with the interactive display surface. A computing system storing machine instructions is in communication with the scanning light source and the light detector. When executed, the machine instructions cause the computing system to illuminate the interactive display surface with the scanning light source, to detect light with the light detector that is reflected from an object after illumination with the light source, and to generate an output signal based on the detected light that has been reflected from an object on or adjacent to the interactive display surface.
