A Development of Reflex HMD - HMD with time delay compensation capability

1 Abstract A Head Mounted Display system suffers largely from the time lag between human motion and the display output. The concept of Reflex HMD to compensate for the time lag is proposed and discussed. Based on this notion, a prototype Reflex HMD is constructed. The rotation movement of the user's head is measured by a gyroscope, modulating the driving signal for the LCD panel, and shifts the viewport within the image supplied from the computer. The merit of this system is: 1) the independence of the computer software/hardware platform; 2) simple, low cost and light weight; and 3) does not cause any additional delay.
