HandBrush

Also known as Line mode, Block mode

The bare hand works like a paintbrush for grouping objects: sweeping the fingertip or palm strings the touched objects together into a group, drawing a loop around objects in view groups them all, and further strokes erase, split or join groups.

How it works

With Pico Neo3 hand tracking and six gestures. Line mode uses the fingertip (thin brush) or the palm (wide brush); objects in the swept space are selected and linked by a line in sweep order, and a confirm gesture makes them a group. Block mode draws a closed loop in view and groups the objects inside it, shown as a coloured block. Erase mode removes objects or whole groups; a stroke across one line or block splits it, and a stroke across several connects them. With 16 participants grouping objects on a plane 10 m away, it was faster and more accurate than ray, screen-rectangle and cone selection, and Split and Connect made changing groups faster.
