GESTURE BASED HUMAN COMPUTER INTERACTION

Apparatus, computer-readable storage medium, and method associated with human computer interaction. In embodiments, a computing device may include a plurality of sensors, including a plurality of light sources and a camera, to create a three dimensional (3-D) interaction region within which to track individual finger positions of a user of the computing device. The light sources and the camera may be complementarily disposed for the camera to capture the finger or hand positions. The computing device may further include a 3-D interaction module configured to analyze the individual finger positions within the 3-D interaction region, the individual finger movements captured by the camera, to detect a gesture based on a result of the analysis, and to execute a user control action corresponding to the gesture detected. Other embodiments may be described and/or claimed.
