Human-computer interaction models and their application in an eye-gaze input system

After analyzing the characteristics of the user in the human-computer interaction process, a user model and an interaction model based on multi-agent intelligence have been set up respectively, and a kind of interaction protocol for eye gazing interaction has been proposed. To verify the models and protocol, some experiments have been done mainly with the eye gazing human-computer interface (HCI), and the results show that the problems which used to exist in the similar interaction processes have been overcome, moreover, the prompt messages from the computer, when it is working, have enforced the user´s learning ability by multimedia, such as vision and voice.
