Disambiguating ninja cursors with eye gaze

Ninja cursors aim to speed up target selection on large or multiple monitors. Several cursors are displayed on the screen with one of them selected as the active cursor. Eye tracking is used to choose the active cursor. An experiment with 13 participants showed that multiple cursors speed up the selection over long distances, but not over short distances. Participants felt the technique was fastest with 4 cursors per monitor, but still preferred to have only 1 cursor per monitor for their own use.
