“Wave Goodbye To The Ordinary User Interface”

Andy Wilson and Nuria Oliver of Microsoft Research are working on new ways of interacting with objects. I imagine the XWand is a stop-gap solution until tracking cameras allow users to point with their fingers. Remote controls make sense for complex interactions like controlling media playback, but I wouldn’t want to have to find a device every time I need to turn a light on.

The dual-webcam gestural and speech interface control sounds pretty cool.
