I remember I tried a VR device in 2000. It consisted of a VR glass with two mini CRT monitors. There was a frame with a bike seat and cable with motors hanging from the ceiling. To fly through the remarkable good 3D world (for its day) there was a heavy glove with some cables attached. It was powered by a Silicon Graphics/SGI super computer standing next by. I never got the same immersive experience that allows one to fly in VR 3D since than. Flying downwards through a mediaeval city 3D environment felt really like being Superman because the whole body was oriented by servo motors. I could fell the blood going in my head. And had the slight fear that the heavy glove falls of my arm. So flying upwards or horizontal gave a better and more rewarding feeling. Nowadays these VR glasses are still heavy, but smaller due to LCD. But we will never get the full immersive experience without a device that moves the body accordingly to the 3D experience.
