Display system, information processing device, projector, and information processing method

A projector comprising:

• a projection unit that projects an image to a projection surface;
• an interface that acquires a pen down event from other projector connected to the projector;
• a central processing unit (CPU) programmed to execute:
• generating a move event and a pen up event that occurred by an operation of a indicator with respect to the image;
• replacing event information of the pen up event to event information of the move event when generating the pen up event in the time between generating the move event and acquiring the pen down event, and
• processing the operation corresponding to the event information of the move event.

A projector control method comprising:

• generating a move event that occurred by an operation of a indicator with respect to an image projected onto a projection surface from the projector;
• acquiring a pen down event from other projector connected to the projector;
• generating a pen up event that occurred by the operation of the indicator;
• replacing event information of the pen up event to event information of the move event when the pen down event is acquired in the time between generating the pen up event and the move event, and
• processing the operation corresponding to the event information of the move event.
