3-D glasses with camera based head tracking

摘要

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.

主权项

1. A method for camera tracking a user's head, the method comprising:
measuring a first ambient light level; determining that the first ambient light level is beyond a first threshold value; tracking, using a camera, the user's head by detecting light reflected from reflective material on a device worn on the user's head, the tracking based on the determination that the first ambient light level is beyond the first threshold value; and outputting a position, orientation, or motion of the user's head based on the tracking.
