We present a novel combination of an eye-gaze interface and an area cursor technique. The area cursor expands from a point cursor when a user looks at a point and becomes a two-dimensional area cursor encompassing an area centered on the user’s gaze point. We apply both the bubble cursor and bubble lens techniques to the eye-gaze interface.





Bubble Gaze Cursor

The bubble gaze cursor is a combination of the eye-tracking interface and the bubble cursor, which is a circular area cursor in a mouse that keeps changing the cursor size dynamically to always contain only one target.






Bubble Gaze Lens

The bubble gaze Lens technique enlarges a small target by activating a magnifying lens when the cursor is close to the goal target and selecting it easily and quickly.

Abstract

We conducted two studies exploring how an area cursor technique can improve the eye-gaze interface. We first examined the bubble cursor technique. We developed an eye-gaze-based cursor called the bubble gaze cursor and compared it to a standard eye-gaze interface and a bubble cursor with a mouse. The results revealed that the bubble gaze cursor interface was faster than the standard point cursor-based eye-gaze interface. In addition, the usability and mental workload were significantly better than those of the standard interface. Next, we extended the bubble gaze cursor technique and developed a bubble gaze lens. The results indicated that the bubble gaze lens technique was faster than the bubble gaze cursor method and the error rate was reduced by 54.0%. The usability and mental workload were also considerably better than those of the bubble gaze cursor.
