Pranav Mistry, Pattie Maes and Liyan Chang from MIT‘s Media Lab have managed to create an invisible computer mouse for just a few dollars. Using an Infrared laser and tracking camera, the Mouseless system registers and interprets a user’s hand movement and translates it into onscreen actions such as cursor movement and button clicking.
While others take the familiar input peripheral to new levels by cramming as many buttons as possible onto it or making the surface available for multi-touch interaction or even moving the whole experience to the end of a user’s leg, Pranav Mistry and colleagues have dispensed with its physical form altogether.
