Abstract: A client can return a display state of an object to the past. When a point body moves on a screen, a projector draws an object of a line representing a moving trajectory. The projector generates object data representing the object and transmits the generated object data to tablet terminals. The object data contains order information representing generation order of the object. The tablet terminals display the object represented by the transmitted object data on a touch panel. When performing an operation for returning the display, the tablet terminals return the display by object unit based on the order information contained in the object data.
