Abstract

The invention consists of the use of an ordinary computer camera to track fingertip movements. The movie captured from an ordinary computer camera is analyzed frame by frame for our purposes. The current method being used is as follows, which consists of two stages--positioning and tracking. In postioning, each pixel is compared with other neighboring pixels. As the finger tip tends to be brighter than its surroundings, if this pixel is bright than its surroundings, it isconsidered to be a "target" pixel. This pixel then undergoes the second stage of tracking. In tracking, the background is removed and movement is analyzed by averaging the greyscales of corresponding pixels in the two frames and subtracting the pixel greyscale from the second frame.
