The apparatus further includes an input device (6) for moving a combination position of an arbitrary object on a screen and a limit judgment unit (8) for judging according to attention area information for identifying an attention area on the screen whether the object instructed to move by the input device (6) is superimposed on the attention area. When the object is superimposed on the attention area, movement or combination of the object is limited according to limit attribute information describing the attribute of the attention area.</p> |
