| Abstract: |
A computer-driven system aids operator positioning of a cursor by integrating eye gaze and manual operator input, thus reducing pointing time and operator fatigue. A gaze tracking apparatus monitors operator eye orientation while the operator views a video screen. Concurrently, the computer monitors an input device, such as a mouse, for mechanical activation by the operator. According to the operator's eye orientation, the computer calculates the operator's gaze position. Also computed is a gaze area, comprising a sub-region of the video screen that includes the gaze position. This region, for example, may be a circle of sufficient radius to include the point of actual gaze with a certain likelihood. When the computer detects mechanical activation of the operator input device, it determines an initial cursor display position within the current gaze area. This position may be a predetermined location with respect to the gaze area, such as a point on the bottom of the gaze area periphery. A different approach uses the initial mechanical activation of the input device to determine the direction of motion, and sets the initial display position on the opposite side of the gaze area from this motion so that continued movement of the input device brings the cursor to the gaze position in a seamless transition between gaze and manual input. After displaying the cursor on the video screen at the initial display position, the cursor is thereafter positioned manually according to the operator's use of the input device, without regard to gaze.

What is claimed is:
1. A computer-implemented method for eye gaze assisted cursor positioning a video screen, comprising:
- operating a gaze tracking apparatus to monitor eye orientation of a computer operator as the operator views a video screen and compute a measured gaze position of the operator upon the video screen according to the monitored eye orientation, and concurrently monitoring a operator input device for mechanical activation by the operator;
- according to the operator's eye orientation, determining a gaze area comprising a sub-region of the video screen including the measured gaze position; and
- suspending display of a cursor until detection of activation of the operator input device, and thereupon computing an initial cursor display position within the gaze area and displaying the cursor upon the video screen at the initial cursor display position, and then moving the cursor across the video screen in accordance with the activation of the operator input device irrespective of gaze.
