Folks from our lab today visited colleagues next door to see the current projects they're working on, some sort of low-cost CAVE and haptic interfaces. Very instructive to try it out live. Quite big pieces of machinery anyway.

In the past twenty years, what were the improvements in haptics? What were the main lessons? What were successes an failures? Does the Wii count here?

Is that the future or the past of entertainment? Why?
