Abstract
Methods, devices, and systems, are described for tracking a video game player's head under different ambient lighting conditions and switching between tracking techniques as lighting conditions change. Based on measurements of ambient lighting conditions, a camera hooked to a game console can (1) track a player's face using facial tracking techniques, (2) track reflective material on the player's 3-D glasses, or (3) turn on or up illumination LEDs mounted on the 3-D glasses.
