Study on cursor shape suitable for eye-gaze input system

The aim of this study was to identify the cursor shape suitable for eye-gaze interfaces. The conventional arrow shape was, irrespective of the number of targets in the display, not suitable for an eye-gaze input system from the perspective of task completion time, number of errors, and subjective rating on usability. It is recommended that the cursor shape of an eye-gaze input system should be cross or ellipse. When the distance between targets is wider, the ellipse type is proper.
