I'm looking for recommendations on eye tracking technology. My primary concern is with the current solutions' lack of precision and resolution. I'm considering a hybrid approach, where eye tracking is combined with mouse movements for improved accuracy. The idea is to use eye tracking to set an initial anchor point on the screen, and then use the mouse to fine-tune the position from that point. For example, if I look at the 'X' button at the top right of a window, the system sets the focus there. This anchor point remains static as long as my gaze stays within a predefined area (like a 3-inch box around the anchor). The anchor point updates only when I shift my gaze to a different area of the screen. Any insights or recommendations on this approach or other effective eye tracking solutions would be greatly appreciated.
