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