I’m starting this thread to let you know about my undergraduate project. It is called iDisplay.
iDisplay is a computer-vision based solution to retrofit regular flat displays into interactive surfaces. It provides a low cost and simple hardware setup.
The hardware prototype includes only a regular off-the-shelf webcam and a regular LCD monitor. No expensive sensors and No IR methods are used.
The main interaction method of iDisplay is the Pinching Gesture. It can also identify circular tangible objects and their colors.
More infomation can be found here.
Really looking forward to know your comments and feedback.
