Project Natal was announced by Microsoft at E3 as new interface peripheral for the Xbox 360, which removes the need for a joypad, instead body movement, facial recognition and voice are used for interaction.

We have seen similar innovations with the EyeToy for the PS2 and the notion detection in the Wii, but both have severe limitations. The EyeToy is a single lens camera, so it is easily affected by lighting and background, while the motion detection in the Wii is built into the joypad and has limited capabilities by default.

The demo shown at E3 is jaw dropping, showing seemingly natural interaction with a character called Milo, but anyone with any experience of Microsoft demos treats them with appropriate levels of scepticism. Since they haven’t beaten the Turing test there is certainly some smoke and mirrors going on, in the words of Milo’s creator Peter Molyneux “If we had, then applying it to a computer game would be the last of the solutions we'd use it for.”
