A holodeck it's not – but this cheap, depth-sensing camera has potential

Tetris – The Movie. Are you ready to BLOCK?

Although this video mainly convinces me never, ever to try getting into Second Life again, the glimpses you get of the actual technology behind this depth-aware webcam are pretty compelling. I think the accuracy and responsiveness need some improvement before it’s ready for mass consumption, but this isn’t meant to be a finished product, simply a demonstration of basic capability.

With a little tweaking, it could perhaps track the features of your face for real-time expressions, or offer the same level of resolution as a mouse by tracking the tip of your finger. It’s all pretty much fantasy at this point, but a proof-of-concept like this is probably what gave birth to the technology behind the Wii. The mouse-and-keyboard (or gamepad) scheme is increasingly inadequate, though we make do with extra buttons and programmable functions. Who’s to say what’s next?
