Sixth Sense – This is very cool technology

This is how computers should be in the future
This demo, from Pattie Maes‘ lab at MIT (and spearheaded by her student Pranav Mistry), was the buzz of TED2009. Sixth Sense is a wearable device with a projection screen that paves the way for profound, data-rich interaction with our environment. Imagine Minority Report and then some.
The SixthSense prototype is comprised of a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks user’s hand gestures and physical objects by the camera and tracks the locations of the colored markers (visual tracking fiducials) at the tip of the user’s fingers using simple computer-vision techniques. The movements and arrangements of these fiducials are interpreted into gestures that act as interaction instructions for the projected application interfaces. The maximum number of tracked fingers is only constrained by the number of unique fiducials, thus SixthSense also supports multi-touch and multi-user interaction.
