Imagine you are in Crossword and you picked up “Inside Steve’s Brain”. Now you would probably take out your phone from the pocket-open up the browser-type URL for amazon-check the ratings and reviews for the book.
Wooh….*time consuming* task to do(atleast I would say that) when compared to Sixth Sense technology.
You might be thinking What the hell am I talking about. So let me answer your WHAT part here.
Almost two years ago a researchers from MIT medialab Pranav Mistry made a pendulum look-alike device that would make any possible physical interface a computer. You might have come across such topics in films. This device allows us to bring the digital information into the real world just by natural hand gestures. Hence making entire world your computer.
The SixthSense device consist of a pocket projector, a mirror and a camera. The hardware components are gathered in a wearable device(like pendant) 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 using computer- vision based techniques. The software program processes the video stream data captured 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.Thus SixthSense also supports multi-touch and multi- user interaction.
As you can see his device has wide variety of applications. Lets say this device can convert your palm into keypad,you can draw 3-D pictures on the wall with the help of your hand gestures,it can turn your bare wrist into virtual wrist watch and any possible thing you can think of.
If you think this device must be really expensive then I say NO,its just $350 and if you are wondering to grab your hands on it then you will have to wait for some more years as the device is under-development. But you can make your own device(device is open source). Instructions on how to make your own prototype can be found here.
