That is completely unnecessary technology for the iPad. Coming from someone who doesn't even like touch screens you could consider me biased. Call me old fashioned but I still like pressing physical buttons.
An anonymous reader writes "Elliptic Labs will reveal their Touchless Gesture User Interface technology at CES 2011. Elliptic Labs sprung forth from the signal processing environment at the University of Oslo and what they've come up with is an [iPad] dock which creates a 'touchless zone' that extends out about 1 foot in front and to the sides of the iPad screen. Users can then initiate a number of gestures, much like on Microsoft Kinect, to manipulate onscreen content."
