Stretch Go-Go

A Go-Go variant where the virtual arm keeps growing while the real hand is held in an outer zone, so reach is unlimited.

How it works

The space in front of the user is divided into concentric zones. Holding the hand in the outermost zone makes the virtual arm extend at a constant rate, the innermost zone retracts it, and the middle zone holds its length; a gauge shows the current zone.
