Tiny Hands
Also known as Adaptive virtual hands
The user shrinks their virtual hand to as little as a tenth of its size and then touches tiny objects directly inside a dense structure within arm's reach.
How it works
With Quest hand tracking, holding the non-dominant palm face-down in view for 2 s activates scaling, and moving that hand up or down enlarges or shrinks the dominant virtual hand between 1.0 and 0.1; holding the palm out again for 2 s deactivates it. The target is selected by touching it with the small hand. Participants mostly chose sizes of 0.2–0.5. With 22 participants selecting 0.4 mm spheres in a 1,192-sphere molecule 0.4 m away, it took 44 s for five targets against 65 s for raycasting and 76 s for pinch-to-select, with no errors.
