“We can turn any surface into a 3D touchscreen,” explained Anup Chathoth of Ubi Interactive.

Such claims typically conjure up images of floating Minority Report-style touchscreens made from curved glass, but that’s exactly what this three-person team has developed.

Ubi’s system uses a  Microsoft Kinect sensor to turn a regular projector into a multi-touch PC projection system, where regular PowerPoints (or other PC application), web pages, even games no longer require clickers or wireless mice to be navigated.

By using the motion-tracking and depth-perception cameras in the Kinect, Ubi is able to detect where a user is pointing, swiping and tapping on a surface and interpret these gestures as if they were being performed on a giant touchscreen or interactive whiteboard.

The low-cost technology can be retrofitted into existing projection systems without any technical experience.
