Abstract
A method for shutter glass eyewear control provides for a command sequence having precise shutter timing and control information for opening and closing the left and right shutters of shutter glass eyewear. The infrared signal commands are offset from the corresponding shutter action to minimize interference while still allowing the eyewear to track changes in the timing of the infrared signal received from a display system. Command sequence encodings are provided for enhanced interference rejection.

16. A method for processing an infrared signal of a command sequence, the method comprising:
-
receiving an infrared signal of a command of the command sequence, the command having shutter timing information for one of opening a left shutter of the shutter glasses, closing the left shutter of the shutter glasses, opening a right shutter of the shutter glasses, and closing the right shutter of the shutter glasses; signal processing the infrared signal of the command to determine logic 1'"'"'s and logic 0'"'"'s in the command; using the command to initialize an action including one of opening the left shutter of the shutter glasses, closing the left shutter of the shutter glasses, opening the right shutter of the shutter glasses, and closing the right shutter of the shutter glasses. - View Dependent Claims (17, 18, 19, 20, 21, 22)
