MIT’s media lab have unveiled a series of short videos demonstrating possible scenarios and advantages of their sixth sense interface — a wearable projected gestural interface. The gestures are based on a multi-touch screen interface but as the interface is projected there is no need for a screen, so mobility is easy and costs are low. It can act as a camera, scanner, video player, phone, internet browser and more! The best demonstration I’ve found is this speech given at TED last month.
