1. A wireless control device, comprising: a base station including a sensor; a housing worn on a body of an operator, said housing including a plurality of optical emitters and a plurity of optical detectors at least one optical emitter and at least one optical detector forming at least one x-axis emitter-dectector pair for detectrg an x-direction of a pointing motion or gesture; at least one optical emitter an at least one optical detector forming at least one y-axis emitter-detector pair for detecting a y-direction of a pointing motion or gesture; and, means for distinguishing between optical beams emitted from said plurality of optical emitters when refected from a body pat of the operator or another object and detected by said opticat detector.
