A multicolored vision-based gesture interaction system

In this paper, we present a novel method for human-computer interaction based on finger motion detection. Image processing is used to get the position, motion direction and movement of the marked figure in the video image, and then associate them with the cursor position, motion direction and mouse function using windows underlying functions. Experimental results show that the method can accurately obtain the characteristic quantities of the marked figure, and actualize cursor movement and mouse clicking. It can be widely used in many fields such as teaching, gaming and computer remote controlling.
