Human Computer Interface Based Virtual Mouse

Computer Engineering

Since the computer technology is growing continuously, Human Computer interaction is gaining its importance enormously. Most of the mobile devices today are using touch screen technology. But, this technology is still not cheap enough to be used on desktop systems. So creating a hand gesture based device such as mouse or keyboard using a sensor(webcam) and computer vision techniques can be an alternative way for the screen touch. Further this technology can be extended to home automation by controlling switch board such as lights on or off with the gesture. The technology is also a boon for handicapped people. Gestures can help a physically challenged person use his/her gestures to control applications in the house like switching on/off television or lights system or door open/close which otherwise would be a difficult task for those people. In this study, hand gesture based a virtual mouse application has been designed and implemented using a regular webcam.
