Investigation to Screen Region Division for Stable Input of Eye-controlled Cursor

Aiming at the problems of stable cursor hovering and "Midas Touch" that are difficult to achieve in the current eye-controlled cursor technology, this paper has carried out an experimental study on the stable input of the eye-controlled cursor: Firstly, divide the screen into several small rectangular areas. When the eye-controlled cursor appears in any rectangular region, the position of the cursor will be fixed at the center of the rectangular region, and there will be no shaking of the eye-controlled cursor in a small range due to the natural wobble of the eyeball pupil. Then, the screen interface UI and icon sizes are adjusted according to the screen division level, to ensure that there is only one click target in each small rectangular area of the screen, and to ensure that there is no ambiguity when clicking on the eye-controlled cursor. Finally, by combining the task completion time, task completion rate, error rate, task difficulty, performance indicators, user satisfaction and other test data information to determine the most appropriate screen division size.
