Techniques such as vision, sound, speech recognition, projective displays and location aware devices allow for a much richer, multi-modal interaction between man and machine. Finger-tracking is usage of bare hand to operate a computer in order to make human-computer interaction much more faster and easier. Fingertip finding deals with extraction of information from hand features and positions. In this method we use the position and direction of the fingers in order to get the required segmented region of interest. INTRODUCTION: Finger pointing systems aim to replace pointing and clicking devices like the mouse with the bare hand.
