In an image control system, with a reactive force on an input device that controls a pointer in a display, a bilateral communication of a pointing device can prevent a sense of discomfort while the system is used by an operator. When a screen image is switched from an image A to an image B, the pointing device activates the reactive force data for the image B after a predetermined amount of time based on the type or the amount of the image data of the screen image B. This enables the application of the reactive force for the image B in synchronization with generation of the screen image B, and thus gives an appropriate reactive force to the input portion of the pointing device when the screen images are being replaced from the image A to the image B.
