Review on Smart Human-Computer Interaction and Power Management using Image Processing

Hand and Face gestures are important factors for human computer interaction. Compared to many existing interfaces, hand and face gestures are easy to use, natural and intuitive. Successful applications of hand gesture recognition include computer gaming, Robotics Field and sign language recognition to name a few. Vision-based recognition systems can give computers the ability of reacting on hand and face gestures. This project gives an overview of the field of hand gesture interaction with Human-Computer and describes the early stages of a project about gestural command sets. Currently we have built a first prototype for exploring the centroid based menus in gesture-based interaction. The purpose is to make task easier without actual interface with the respective device. With the ever-increasing dissemination of computers into the society, it is widely believed that present popular mode of interface with computers (mouse and keyboard) will become a bottleneck in the effective utilization of information. It has the potential to be a powerful tool sustaining well-organized and spontaneous interaction between the human and the computer.
