Abstract
Various embodiments provide a method for determining conditions associated with the presence of a user in order to perform object detection. For example, various heuristic tests can be used to identify movement within a sequence of images or to identify user engagement therewith and, if movement or user engagement is identified, stereo disparity can be computed in an attempt to detect an object within a predetermined distance of the computing device. Accordingly, if the distance of the object is within the predetermined distance, object detection is performed. If the object is beyond the threshold distance, however, object detection is not performed in order to conserve battery life of the computing device.
