There was a long line at CES for the "gaming chair" and everyone seemed to want to do just one thing -- race a Formula One very, very fast. Not that there's anything wrong with that.

Unlike other gaming chairs, this D-Box chair, dubbed the GP-100, doesn�t simply vibrate in synch with game play, it actually moves as well, tilting and rocking. I was getting dizzy just watching. The secret is the chair�s motion actuators. They resemble shock absorbers that move slowly like pistons in close integration with what is happening in the game. The company calls the patented technology the "Integrated D-BOX� MOTION CODE�."

When I talked to excited participant, he said "Damn! It's just like driving a race car!."

As the web site says:

Integrated motion systems use a two, three or four actuators to lift and move your seating in perfect synchronization with the onscreen action and sound, creating a virtual-reality experience in your living room or home theater.

All of this costs a pretty penny, as you might imagine. Figure on the gaming chair costing $15,000, and that does not include a television screen, PC (a Voodoo gaming tower was used for the demo) or games. What consumers get for that is the chair, its actuators and the D-Box controller, a box that takes signals from games specially encoded for the motion chair and translates them into physical movement. I think we'll probably see this in arcades and movie theatres, with not much home use.
