  • Gesture recognition goes hand in glove with PC commands

    Controlling computers with just a swipe of the hand is already gaining interest in the tech world thanks to the likes of Microsoft's Project Natal.

    Researchers at the Massachusetts Institute of Technology (MIT) are working on their own gesture control system, using the multicoloured Lycra glove, pictured here. The glove costs just $1 to manufacture.

  • The system works by using an off-the-shelf webcam to track the movements of the multicoloured glove and then uses software to map its movements onto a 3D computer-generated model, as seen here.

    The glove is covered with 20 irregular-shaped patches, which allow the camera to recognise the front and back of the hand.

    The patterns are painted in 10 different colours, composed of a palette chosen to maximise their contrast with the background and each other, and make them easier for the webcam to pick out.

    The system, produced by students within the Computer Science and Artificial Intelligence Laboratory, is able to map even fine movements, such as pinching two fingers, on the model.

  • The system is powered by a software algorithm, developed at MIT, that is able to rapidly look up visual data in a database.

    The software captures a picture of the hand, automatically crops out the background and then matches the picture against a database of myriad hand positions - all in a fraction of a second.

    Aside from the obvious uses for gesture control to manipulate an operating system, researchers say the glove could be useful to engineers or designers looking for a more intuitive way to manipulate 3D computer-generated models of products or structures, as seen here.
