Interactive control mechanism using a color wearable mask

Gestures play a key role in making interaction of human with computers with ease. The idea of this paper is to use rotation of finger as a gesture. Since detection of rotation of bare finger is difficult, we employed a mask to be put on finger with a specific pattern of colors printed on mask. When finger is rotated in front of camera then area of respective colors on mask get changed in images captured from camera. This change in area is taken as measure of rotation. So using image processing techniques we find out the rotation of the finger based on difference in areas of respective color regions in respective frames. The shape of the color strips are chosen as a triangle.
