The folks at Technology Review have run up a top ten of futurismic display/interface combos, all on display at SIGGRAPH 2009, I particularly like the haptic holography from researchers at the University of Tokyo:
The virtual objects appear in mid-air thanks to an LCD and a concave mirror. The sensation of touching the objects is created using an ultrasound device positioned below the LCD and mirror.
It’ll be interesting to see whether people end up using more traditional haptic devices like gloves and goggles combinations, or choose something based on holography and sound waves.
Also note that Wii remotes are used as off-the-shelf sensors, the street, or academia, finds its own use for things.
