GazeRing
Also known as GazeRing-Slide, GazeRing-Tap
A pressure-sensing ring on the index finger works with gaze: a long press opens a cone around the gaze, thumb slides or taps on the ring refine the cone and step through the objects in it by depth, and another long press selects.
How it works
On a HoloLens 2, a flexible pressure sensor on a ring is operated by the thumb in two modes: sliding in eight directions (GR-S) or tapping five areas (GR-T). A 1.5 s press opens a 6° gaze cone; sliding or tapping shifts it to correct eye-tracking error; up and down step through the objects inside by depth, making the others transparent; a long press confirms. The hand can stay out of the cameras' view. With 16 participants, both GazeRing modes were faster than gaze-and-speech and gaze dwell when targets were occluded or eye tracking was off by 2–3°, and GR-T was preferred.
