DualGaze

Also known as Gaze confirmation flag

Gaze-only selection with a confirmation flag: looking at a button makes a small flag pop up where your gaze entered it, and glancing back at the flag confirms.

How it works

When the gaze enters a selectable element and stays for 0.3 s, a small confirmation flag (about a quarter of the button) appears at the point where the gaze entered, i.e. behind the gaze path. Confirming therefore needs a deliberate look back, which a scanning gaze rarely does, avoiding the Midas Touch problem; looking elsewhere cancels. A pilot showed this trajectory-adaptive flag placement beat a fixed flag position. In a gaze-typing study (N=27, FOVE VR headset), DualGaze was significantly more accurate than 1 s dwell (Fixed Gaze) at similar overall speed, and became faster with practice.
