1. A method of controlling objects in a 3-D (three-dimensional) space using a handheld controller, the method comprising:

  • storing an object database that associates multiple controllable objects with respective control locations of the controllable objects in the 3-D space, each control location representing a respective region in the 3-D space to which the handheld controller can be pointed to control the respective controllable object;

    measuring a location of the handheld controller in the 3-D space;

    measuring an orientation of the hand-held controller in the 3-D space;

    combining the measured location of the handheld controller with the measured orientation of the handheld controller to construct a virtual ray, the virtual ray having an origin placed at the measured location of the handheld controller and a direction based on the measured orientation of the hand-held controller; and

    in response to the handheld controller pointing such that the virtual ray intersects a control location of a controllable object in the object database, (i) accepting user input by the handheld controller for controlling the controllable object, and (ii) transmitting control instructions from the handheld controller for controlling the controllable object based on the user input.
