Abstract
A coordinate input apparatus responsive to physical movement of an operation section for moving and displaying a cursor displayed on a display screen at a corresponding coordinate position on the display screen has a unit for deciding a ratio of cursor movement which detects the operation speed of the operation section and decides the ratio of cursor movement on the display screen for a predetermined amount of the movement of the operation section based on the operation speed. A display unit moves and displays the cursor on the display screen corresponding to the amount of movement of the operation section based on the ratio of cursor movement thus decided. As a result, even if the amount of movement of the operation section is constant, when the operation section is moved at a high speed, the cursor moves a long distance; whereas, when the operation section is moved at a low speed, the cursor moves a short distance.
