With several companies developing technologies that can turn any surface into a touchscreen, it should be widely available soon. Those who want to try it out before it's cool, however, should look towards Ubi Interactive's software that combines the talents of Microsoft's Kinect for Windows sensor and a projector. So long as the software's installed on a Windows 8 computer, the sensor tracks and detects movements users make on the projected image. Interactions are the same as any tablet or smartphone, including launching icons by tapping on them and expanding areas with pinch-to-zoom. Merely a concept in 2012, the software is now available on Ubi's website with prices ranging from $149 to $1,499, depending on the display size and the type of customer support. Sounds like even an Average Joe can nab one, assuming they already have a projector and one of Microsoft's $250 motion / voice detectors.
