One new technology that is gaining steam in the public eye is that of the multi-touch display. Some applications are being used for in home while others are for out of the home – this system is more for an out of the home environment from the information we have on it. I think that arcades could make better use of such technology although they have at least begun to do so with systems like LightSpace and TrioTech’s UFO Stomper. And to prove how good such a system could be for arcades, these guys retrofitted a system called Obscura Digital Multi-Touch wall to play Atari’s Missile Command, although they modified the game a bit to include unlimited ammo (which sure helps when this game gets crazy).
