HEAD MOUNTED DISPLAY SYSTEM CAPABLE OF INDICATING A TRACKING UNIT TO TRACK A HAND GESTURE OR A HAND MOVEMENT OF A USER OR NOT, RELATED METHOD AND RELATED NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM

摘要

A head mounted display system (1, 1', 1", 1"') includes a head mounted display, a tracking unit (14, 14', 14", 14"'), a switch unit (15, 15', 15", 15'") and a processing unit (13, 13', 13", 13'"). The head mounted display is for displaying images to a user. The tracking unit (14, 14', 14", 14'") is for tracking a hand gesture or a hand movement of the user in a first state or not to track the hand gesture or the hand movement of the user in a second state. The switch unit (15, 15', 15", 15'") is for generating an activating command when a state of the switch unit (15, 15', 15", 15'") is changed. The processing unit (13, 13', 13", 13'") is coupled to the tracking unit (14, 14', 14", 14'") and the switch unit (15, 15', 15", 15'") for switching the tracking unit (14, 14', 14", 14'") between the first state and the second state in response to the activating command. Therefore, it can save power consumption and prevent an unexpected output due to an unexpected tracking result of the tracking unit (14, 14', 14", 14'").
