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.
30-Sec Fast Forward
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.
