Abstract

Time lag between the human motion and display output is a large obstacle that prevent the Head Coupled Display from application. A novel HMD "Reflex HMD", with time lag compensation was proposed and the preliminary prototype was constructed. The angular movement is measured by gyroscope in this HMD, modulates the driving signal for LCD panel, and shifts the viewport within the image supplied from the computer. The merit of this system is 1) the independece of computer platform, operating system, and application, 2) low cost and light weight, 3) precise compensation without causing additional delay. An experiment with the prototype ReflexHMD successfully showed that the delay of about 100 milliseconds (six frames) was decreased within one frame.
