Abstract

An interactive display including a cover glass having a front surface including a viewing area provides an input / output I / O interface for a user of an electronic device. One arrangement includes a processor, a light source, and a camera positioned coplanar with or behind the cover glass outside the periphery of the viewing area. The camera receives scattered light generated by the interaction of light output by the interactive display with an object, the output light is received from the object by the cover glass and directed toward the camera. The processor determines an azimuth of the object relative to an optical axis of the camera and / or a distance of the object from the camera from image data output by the camera.
