3D Selection Vault

PinchCatcher

Also known as SemiDwell, SemiSwipe, SemiTilt, SemiNDH

Multi-selection for Gaze + Pinch: hold a half-closed pinch and gaze at objects to add them to a group, then close the pinch to act on all of them.

How it works

Holding the index finger and thumb 2–7 cm apart (a semi-pinch) enters a quasi-mode for multi-selection; completing the pinch ends grouping and starts the action (e.g. drag and drop) on the whole group. While in the semi-pinch, gaze points and each gazed object is added by one of four confirmations: SemiDwell (dwell), SemiSwipe (thumb swipe), SemiTilt (hand tilt) or SemiNDH (a pinch of the non-dominant hand). Compared with a CTRL-key-like baseline (FullDH: hold a non-dominant pinch, add with dominant pinches) on a Meta Quest Pro with 40 targets on a grid 13.5 m away; SemiSwipe and SemiDwell were preferred. Demonstrated for file management and RTS games.
