Abstract
An interactive display, including a cover glass having a front surface that includes a viewing area provides an input/output (I/O) interface for a user of an electronic device. An arrangement includes a processor, a light source, and a camera disposed outside the periphery of the viewing area coplanar with or behind the cover glass. The camera receives scattered light resulting from interaction, with an object, of light outputted from the interactive display, the outputted light being received by the cover glass from the object and directed toward the camera. The processor determines, from image data output by the camera, an azimuthal angle of the object with respect to an optical axis of the camera and/or a distance of the object from the camera.
