Researchers Show That Any Flat Surface Can be Turned Into a Giant Multi-Touch Device

The Kinect-based system could enable game devs to turn tables or other flat surface into touch "controllers"
Pinch-to-zoom; two fingered swipe; the scissors gesture -- our fingers are marvelous at multi-touch gestures on tablets or other devices. But what if you could take that concept and add multi-touch gestures to any surface -- no capactive touch screen necessary.
Electrical and Computer Engineering
Professor Niklas Elmqvist
demonstrated the patent-pending system that uses Microsoft Corp.'s (
Kinect visualization device
and can detect hand posture with 98 percent accuracy.
Using the Kinect sensor, which uses imaging technologies to
determine the position of objects in 3D space
, the new software transforms everyday surfaces into virtual multi-touch screens. Comments co-author and Purdue Mechanical Engineering
Professor Karthik Ramani
, "We project a computer screen on any surface, just a normal table covered with white paper. The camera sees where your hands are, which fingers you are pressing on the surface, tracks hand gestures and recognizes whether there is more than one person working at the same time."
Using a proprietary computer model of the human hand, the researchers can use the pixel processing power of the Kinect sensor to pick out finger location, where the hand is in relation to the surface, and left vs. right hand. Comments Professor Elmqvist, "We can isolate different parts of a hand or finger to show how far they are from the surface. We can see which fingers are touching the surface. With this technology, you could potentially call up a menu by positioning your hand just above the surface."
Purdue researchers have developed virtual multi-touch, much like that depicted in the movie
The professors are currently working to refine the accuracy of their method, which was presented in
a research paper
Association for Computing Machinery Symposium on User Interface Software and Technology
(ACM UIST 2012) in Cambridge, Mass.
The technology could be used to add inexpensive multitouch to a variety of traditional electronics devices including TVs, computers,
, and appliances. Comments Professor Elmqvist, "Imagine having giant iPads everywhere, on any wall in your house or office, every kitchen counter, without using expensive technology. You can use any surface, even a dumb physical surface like wood. You don't need to install expensive LED displays and touch-sensitive screens."

It certainly is an exciting possibility to think about, and Microsoft is surely pleased that this is all made possible with its proprietary, patent-protected Kinect sensor.

RE: Touch vs Mouse

thirded. i prefer a stylus for mobile applications where the screen is small. smaller tool = higher accuracy.
i think that gaming will never evolve to use this new technology. it already appears that people prefer not to play FPS's with a gun peripheral, so i can't imagine that pointing directly at the screen with your finger is going to be any more enjoyable.
the mouse will never die.
