System and method for selecting and activating a target object using a combination of eye gaze and key presses

摘要

A pointing method uses eye-gaze as an implicit control channel. A user looks in a natural fashion at a target object as a button on a graphical user interface and then presses a manual selection key. Once the selection key is pressed, the present method uses probability analysis to determine a most probable target object and to highlight it. If the highlighted object is the target object, the user can select it by pressing a key such as the selection key once again. If the highlighted object is not the target object, the user can select another target object using additional keys to navigate to the intended target object.
