When a touch operation on a touch-panel display module (14) of an electronic device (10) has been detected, display entities (M1 to M4) corresponding to the touched objects are created. The display entities (M1 to M4) are superimposed on the touched positions on a display screen (G). A projector (20), an external display device, projects the display entities onto a screen (30). Even when the display screen of the electronic devices has been moved by a touch operation, the audience looking at a screen page (G) displayed on the screen (30) can see the touch positions in the form of the display entities (M1 to M4), making it possible to understand the meaning of the operator's touch operation. |
