1. A computing system, comprising:

  • a logic subsystem; and

    a data-holding subsystem configured to hold instructions executed by the logic subsystem to instantiate;

    a depth image analysis module to track a world-space pose of a human in a fixed, world-space coordinate system;

    an interaction module to establish a virtual interaction zone with a moveable, interface-space coordinate system that tracks the human and moves relative to the fixed, world-space coordinate system; and

    a transformation module to transform a position defined in the fixed, world-space coordinate system to a position defined in the moveable, interface-space coordinate system.
