What's in the eyes for attentive input

The potential of eye-tracking systems among Attentive User Interfaces (AUI) with new channels of computer input based on computer vision is discussed. The hypothesis is that where the user looks contextualizes much of the user's action and hence can be applied to facilitate human-computer interaction (HCI). Eye tracking is used in combination with other sources of information, such as the current interaction task and the location of screen objects that might capture user attention. The ultimate goal is of integrating this information with manual control actions.
