Object position determination

摘要: In embodiments, apparatuses, methods and storage media for human-computer interaction are described. an apparatus may include one or more light sources a camera. Through capture of images by the camera, computing device detect positions objects user, within three-dimensional (3-D) region which to track user. The utilize multiple sources, be disposed at different distances display illuminate in direction other than image direction. selectively individual facilitate detection toward display. camera also synchronization with selective illumination. Other embodiments described claimed.
