Abstract
When a touch operation on a touch-panel display module of an electronic device has been detected, a display entity corresponding to the touched object is created. The display entity is superimposed on the touched position on a display screen. A projector, an external display device, projects the display entity onto a screen. Even when the display screen of the electronic device has been moved by a touch operation, the audience looking at a screen page displayed on the screen can see the touch position in the form of the display entity, making it possible to understand the meaning of the operator's touch operation.
