摘要：People with physical disabilities can do many things with their eyes that they would otherwise do with their hands. Simply by looking at control keys displayed on a computer monitor screen, the user can perform a broad variety of functions including environmental control, sending emails, browsing the Internet, playing games, typing, and controlling most PC. This project is base on the application of eye movements to user interfaces both for analyzing interfaces, measuring usability, and gaining insight into human performance and as an actual control medium within a human-computer dialogue. The eye movements do not affect the interface in real time. As a direct control medium, the eye movements are obtained and used in real time as an input to the user-computer dialogue. They might be the sole input, typically for disabled users or hands-busy applications, or they might be used as one of several inputs, combining with mouse, keyboard, sensors, or other devices. Interestingly, the principal challenges for both retrospective and real time eye tracking in human-computer interaction turn out to be analogous. For retrospective analysis, For real time use, the problem is to find appropriate ways to respond judiciously to eye movement input, and avoid over-responding; it is not nearly as straightforward as responding to well-defined, intentional mouse or keyboard input.
