Cursor shift speed control system
First Claim
1. A cursor shift speed control system, comprising:
- a mouse input means for actuating a cursor on a display so that the cursor moves in response to movement of the mouse input means;
input means for detecting a moving speed of the mouse input means;
correction means connected to the mouse input means, for comparing the moving speed of the mouse input means with a predetermined threshold value set int he correction means, and for calculating corrective values, wherein the greater the moving speed of the mouse input means compared to the predetermined threshold value, the greater the corrective values;
cursor speed calculation means connected to the input means and the correction means, for calculating a corrected cursor speed on the display screen by adding the corrective values one by one to the moving speed of the mouse input means, wherein the corrective values are added one by one as the moving speed of the mouse input mans becomes progressively greater than the predetermined threshold value, whereby the corrected cursor speed is increased from a linear relationship between the moving speed of the mouse input means and the corrected cursor speed to a nonlinear relationship between the moving speed of the mouse input means nd the corrected cursor speed, a rate of change of the corrected cursor speed increasing progressively in accordance with the corrective values added to the moving speed of the mouse input means;
cursor display processing means connected to the cursor speed calculation means, for displaying the cursor on the display screen by successively calculating a displaying position of the cursor based on the corrected cursor speed.

Abstract
A document preparing system includes input processing means for detecting the per-unit-time moving amount of a click such as a mouse and for supplying information to be used for calculation for correction; correction means for executing a calculation for correction based on information supplied from the input processing means and for supplying a corrective value; and mouse cursor moving amount calculation means for calculating the per-unit-time moving amount of a mouse cursor using the corrective value and the per-unit-time mouse moving amount. As the mouse moving speed is higher, the mouse cursor moving speed is further increased. This enables to closely reproduce the mouse user'"'"'s operation feeling that a fine movement of the mouse is slowly made while a rough movement thereof is quickly made. This improves a smooth operational effectiveness of the mouse.
