Abstract
The main method of interacting with computers and consumer electronics has changed very little in the past 20 years. This paper describes the development of an exciting and novel Human Computer Interface (HCI) that has been developed to allow people to interact with computers in a visual manner. The system uses a standard computer web camera to watch the user and respond to movements made by the user’s hand. As a result, the user is able to operate the computer, play games or even move a pointer by waving their hand in front of the camera. Due to the visual tracking aspect of the system, it is potentially suitable for disabled people whose condition may restrict their ability to use a standard computer mouse. Trials of the system have produced encouraging results, showing the system to have great potential as an input medium. The paper also discusses a set of applications developed for use with the system, including a game, and the implications such a system may have if introduced into everyday life.
