PROBLEM TO BE SOLVED: To improve the operability of a projection system performing projection by using a plurality of projection devices when a user operates a terminal device to control the projection devices.SOLUTION: When an explainer directs the apical surface of a pointer to any of screens, flicker is detected. An operation device proceeds processing from step S202 to step S203, analyzes the flicker to detect the frequency of the flicker, and determines the names of a PC and PJ from the detected frequency (step S204). The operation device transmits, to a personal computer PC to which the projector PJ determined in the processing of step S204 is connected, desired operation and the name of the PJ (the name of the determined projector PJ) (step S205). The desired operation is the operation designated by the explainer by operating buttons provided on the pointer including, for example, switching from an image currently projected and displayed to another image. |
