BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointing position correcting method for a coordinate pointing device, and more specifically, it is displayed on the screen of an information processing device such as a personal computer when a coordinate pointing device represented by a mouse is operated. The present invention relates to a method for correcting the indicated position.

[0002]

2. Description of the Related Art Generally, as a method for operating a personal computer (hereinafter abbreviated as a personal computer), a user inputs a character called a command from a keyboard to a user's operation instruction. A CUI (Character User Interface) and a pointing device such as a mouse ( Using the image position pointing device) to operate the pictures and characters on the screen and input commands G
There is a UI (Graphical User Interface).

When operating a personal computer using a mouse in the GUI, the pointer is moved while confirming what is called a pointer displayed on the screen of the personal computer, which indicates the operating position of the mouse. By pressing a button and operating (clicking) a pattern called an icon on the screen, the PC is operated and various instructions are given.

By using a GUI on a personal computer,
Compared to the case where the operation is performed by the CUI, the user does not have to memorize the command for giving an instruction to the personal computer, and anyone can easily operate the personal computer.

Next, a method for transmitting mouse movements in a personal computer will be described by taking a so-called mechanical mouse as an example.

Usually, the mechanical mouse body is constructed as follows. First, the housing that forms the mouse body is provided with a button to click the screen of the personal computer,
A rubber sphere or a metal sphere covered with a rubber film is housed in the housing. The sphere is in contact with a flat surface of a desk or the like for operating a mouse through a small-diameter hole provided at the bottom of the mouse case.

When the user operates the mouse, the grounded sphere rotates, and the rotational movement of the sphere is transmitted to the roller provided in the housing to read the movement of the mouse. A disk-shaped component called a capstan is attached to the tip of the shaft taken out from the roller. This capstan has a thin slit.

Further, a light emitting diode as a light emitting portion and a phototransistor as a light receiving portion are provided at positions symmetrical with respect to the disc of the capstan. The light emitted from the light emitting diode passes through a slit provided in the disk of the capstan and is received by the phototransistor. At this time, when the light passing through the slit is received by the phototransistor, it is received as blinking light. Therefore, the phototransistor can detect the number of times the light is received.

The above-mentioned roller, capstan, light emitting portion and light receiving portion are collectively referred to as a rotary encoder. This rotary encoder is provided in the vertical (X-axis) direction and the horizontal (Y-axis) direction, respectively, in order to detect the vertical and horizontal movements of the sphere.

The vertical and horizontal movements of the mouse detected by the rotary encoder are IC (Integrator) called a mouse controller provided inside the mouse as a detection signal.
tedCircuit) sent to the chip. The detection signal sent to the mouse controller is converted into data on the movement amount and the movement direction and transmitted to the personal computer, so that various operations in the personal computer can be executed.

However, from the perspective of a further increase in the number of personal computers and internet users using personal computers in the future, some obstacles can be considered.

One of the factors contributing to the increase in the number of personal computer users is the increase in the number of elderly people who use personal computers. One of the effects that elderly people can expect from using personal computers is that elderly people who have time and money can learn how to operate personal computers and use the Internet etc. to send emails and information. Through exchange, it becomes easier to contact with distant family and friends. Alternatively, it becomes possible to expand new exchanges with strangers by utilizing the Internet or the like. In addition, the use of personal computers can be expected to promote the active participation of the elderly in society and prevent them from becoming isolated from society.

However, it is expected that it will be difficult for the elderly to operate the GUI of a personal computer, especially the mouse, by hand. The mouse is an essential part of modern computer operation. In addition, if you can learn the mouse operation, you will learn the important elements in PC operation. If it becomes possible to operate the mouse more easily than before, it will be possible to assist the use of personal computers by many people who have been shy from personal computers until now, mainly in the elderly.

In addition to the mechanical mouse described above, various coordinate pointing devices are used in personal computers. First, in addition to the mechanical mouse, an optical mouse that optically reads the movement amount of the mouse instead of rotating the sphere, or by tracing with a finger etc. on the flat plate provided in the computer body as a substitute for the mouse There is a pressure-sensitive or capacitive touch pad that gives instructions, and a so-called track point that is a coordinate pointing device provided on the keyboard of the personal computer in a protruding shape. Besides this, the mechanical mouse was turned upside down. A so-called trackball or the like in which a sphere provided in the main body of the personal computer with such a shape is operated by a finger or the like can be given.

Further, in the information processing apparatus other than the personal computer, a touch screen operated by the user touching the screen, a joystick operating a lever or the like can be used as the coordinate pointing device.
