Multi-Touch Smartphone Progressive Refinement

Also known as Smartphone SQUAD with CountMarks

A SQUAD-style progressive refinement in VR driven by a smartphone: a sphere cast gathers candidates into four quadrants, and when a quadrant holds few items the user picks one directly by touching with that many fingers and swiping toward it.

How it works

With a Rift CV1 and a Galaxy S8 used as the controller, a sphere is cast at the ray's hit point and the objects inside are spread over a four-quadrant menu (up to 16 per quadrant). If a quadrant holds four or fewer items, touching the screen with N fingers highlights the Nth item in every quadrant and swiping toward a quadrant selects it in one step (CountMarks); otherwise a swipe chooses the quadrant and refinement repeats.
