The future is looking bright for people looking for an excuse to touch themselves and other ad hoc surfaces with purpose, literally. Chris Harrison of the Human-Computer Interaction Institute at Carnegie Mellon University and Microsoft researchers Hrvoje Benko and Andrew Wilson have been focusing their efforts on creating OmniTouch technology that expands touchscreen surfaces beyond the normal array of touchscreen devices like the phones and tablets that we have all become so accustomed to. They realized that the average human hand has more surface area than most touchscreen phones and that there were a lot of usable surfaces already existing in the real world, like your hand, coffee tables and notepads, that could be put to better use. According to Benko,
Find out how this is possible after the break.
The hardware involved at this stage of research simply consists of a depth sensing camera (Kinect) and a pico projector. The software is a lot more complicated since the system is constantly recognizing the surface, interface and calculating the relation of your hand with regards to the surface within a depth map. In a trial with 12 people 6,048 clicks were successfully perceived at 96.5% accuracy, which is comparable to the accuracy rate of other common touchscreens.
As of right now, the application is limited to 2D surfaces but 3D experimentation is not out of the question. As far as the Johnny 5 robot head sitting on their shoulders, Microsoft doesn't expect shrinking the hardware down to a matchbox size is out of the question but Microsoft hasn't expressed interest in commercializing this technology yet either. I seriously hope they will.
