Implementation of virtual mouse based on machine vision

A method to implement virtual mouse through machine vision are proposed. Firstly we present an efficient algorithm based on color to track the movement of fingertips in real time, then we present a set of messages (including elementary fingertip message and simulated mouse message) that are generated according to the result of fingertip tracking, These messages can be used to control the window based applications. We also presents a framework to help programmers realize human-computer interaction based on virtual mouse. The performance of virtual mouse shows a great promise that we will be able to use this methodology to control computers and achieve a more natural human-computer interaction.
