(Touch → Spacial → Scale → Four Point Scale Gesture “4-Finger-Scale”)

This gesture can be activated when four touch points are recognized on a touch object. The relative separation of the touch points are tracked and grouped into a cluster. Changes in the separation of the cluster are mapped directly to the scale of the touch object.
