1. A system, comprising:
- at least one light source in a movable hand-held device;
at least one light detector that detects light from said light source; and
a control unit that receives image data from the at least one light detector, wherein the control unit detects the position of the hand-held device in at least two-dimensions from the image data from the at least one light detector and translates the position to control a feature on a display.

23. A system comprising:
-
two or more movable hand-held devices, each hand-held device comprising at least one light source, at least one light detector detecting light from the at least one light source of each of the two or more hand-held devices a control unit that receives image data from the at least one light detector, wherein the control unit detects the positions for each of the two or more movable hand-held devices in at least two dimensions from the image data from the at least one light detector and translates the positions for each of the two or more movable hand-held devices to separately control two or more respective features on a display.
