In the field of Mixed Reality, one area of Virtual Reality, the method of merging virtual and real spaces have been often discussed. A chromakey-imposer is often used to synthesize CG and real images, but the relation between CG and real images is either in front or behind because a general chromakey-imposer has only one chromakey plane. To make one advance in the former method of merging we propose a method to make a visual effect as if a real space is embedded in a virtual space by dividing an object space into three layers and using two chromakey planes. We tested the visual effect by treating the object space as a studio space which has a large area and a desk space which has a small area.

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.
