Fixed-Length Offset

A virtual hand cursor pushed a constant distance further out along the head-to-hand direction, so out-of-reach targets can be touched.

How it works

The cursor sits on the line from the head through the hand, displaced by a fixed length beyond the hand. Compared in an ISO 9241-9 Fitts' law study with No Offset (virtual hand), Linear Offset and a Go-Go offset, with a controller and with Leap Motion hand tracking in an HMD.
