An imager (12) having a field of view extending along three orthogonal axes detects positions (37) of a data appliance manipulated by a person in the field of view, detects the value of a toggle property (42, 72) of the data appliance manipulated by the person, and outputs a signal (13) which is equivalent to the position, left click, and right click signals from a computer mouse. |
