Patent ID: 8747224

Claim:
An information processing system, comprising: a plurality of operation devices each comprising a light emitting portion; and an information processing apparatus to be communicably connected to the plurality of operation devices, wherein the information processing apparatus comprises: a detector that detects light emitted from the light emitting portion and identifies a position of each of the plurality of operation devices based on a position of the detected light, wherein each of the plurality of operation devices causes the light emitting portion to emit the light with a different light emission color, wherein the information processing apparatus assigns, to each of the plurality of operation devices communicably connected thereto, a unique logical number for identifying each of the plurality of operation devices, wherein each of the plurality of operation devices causes the light emitting portion to emit the light with the light emission color determined based on the unique logical number assigned to the operation device, wherein the information processing apparatus further presents candidates for the light emission color to a user of one of the plurality of operation devices, and transmits, to the one of the plurality of operation devices, an instruction to cause the light emitting portion of the one of the plurality of operation devices held by the user to emit the light with a color selected by the user from among the candidates for the light emission color, wherein the one of the plurality of operation devices causes the light emitting portion to emit the light with the color corresponding to the transmitted instruction, and wherein the information processing apparatus excludes a light emission color of another one of the plurality of operation devices from the candidates for the light emission color to be presented.
