A Computer Vision Based Collaborative Augmented Reality Method For Human-Computer Interaction
Computer vision is becoming very popular now a days since it can hold a lot of information at a very low cost. With this increasing popularity of computer vision there is a rapid development in the field of virtual reality as it provides an easy and efficient virtual interface between human and computer. At the same time much research is going on to provide more natural interface for human-computer interaction with the power of computer vision .the most powerful and natural interface for human-computer interaction is the hand gesture. Hand replaces the currently used cumbersome and inefficient devices like mouse and keyboard and with the bare hands one can easily communicate with the computer. This paper explores a system where hand gesture can be effectively used as a password in the login process for authentication of a person using just a simple web camera. Also this technique does not need any special device like head-mounted display, gloves or any special camera that operates beyond visible spectrum. So with this idea, with a simple video camera and bare hands, a person can interact with computer.
