First Claim
1. A method of moving and displaying a cursor on a display screen in response to physical movement of an operation section comprising the steps of:
- detecting an amount of physical movement of the operation section during a predetermined period of time;
calculating an amount of physical movement per unit time of the operation section from the detected amount of physical movement of the operation section and said predetermined period of time;
deciding a ratio of an amount of movement of the cursor on the screen to a predetermined amount of physical movement of the operation section according to the calculated amount of physical movement of the operation section per unit time; and
moving and displaying the cursor on the display screen corresponding to the amount of physical movement of the operation section on the basis of the decided ratio of the movement of the cursor.

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.
