Abstract
A method and system for optically detecting a user. A sequence of patterns of radiation reflected from an object in a room may be captured by a device. The patterns of radiation may be infrared radiation emitted from the device. A sequence of variations between the captured sequence of patterns of radiation and the emitted sequence of patterns of radiation may be determined and object characteristics of an object may be determined based upon the sequence of variations. The object characteristics may be a sequence of dimensions of the object and a sequence of locations of the object. The method may determine the first is a user based upon the determined object characteristics and a room profile. The room profile may include a plurality of object characteristics of one or more objects in the room.
