Patent 8363098 was granted and assigned to Poly on January, 2013 by the United States Patent and Trademark Office.
Methods and apparatuses for reporting user presence associated with orientation and proximity of a user to a display device are disclosed. In one example, image data associated with a head mounted device and one or more infrared light sources is captured and processed to identify the presence of infrared light source objects. A detection status is output based on the presence of infrared light source objects, and the detection status is translated to an associated user presence state.
