Some users cannot grasp the joystick with their hands or feet, and their limbs and eyeballs are poorly controlled and unstable. All existing eye tracking and joystick mouse systems cannot meet the limitations of their physical capabilities. Therefore, we developed an automatic screen scanning system to solve this problem. The system only uses four vowels [a, e, I, o] to control the cursor's movement direction [ up, down, left, right ] which is used the first vowel, the other vowels have used to control the mouse click behavior [ left click, right click, double click and drag n drop], and its movement speed.
