Abstract

A remote instruction transmission/reception system has a first transmission/reception apparatus, a plurality of second transmission/reception apparatuses, and an information processing apparatus. The second transmission/reception apparatuses each make a selection (choice) and emit an electromagnetic wave. The information processing apparatus transmits an instruction for electromagnetic wave emission states of the second transmission/reception apparatuses according to the selections, to the second transmission/reception apparatuses through the first transmission/reception apparatus. The second transmission/reception apparatuses transmits electromagnetic waves based on the light emission states according to the selections, and when the first transmission/reception apparatus receives the electromagnetic waves emitted from the second transmission/reception apparatuses, the information processing apparatus recognizes the selections made by the second transmission/reception apparatuses based on the light emission states of the electromagnetic waves and categorizes the second transmission/reception apparatuses into groups based upon the selections.
