DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointing cursor calibrating device for calibrating the position of a pointing cursor when an analog value is input by a pointing device used as an input device of a personal computer, and a calibration of the pointing cursor position. About the method.

2. Description of the Related Art As an input device of a desktop personal computer (hereinafter referred to as a personal computer), a pointing device such as a mouse for inputting figures and the like, in addition to a keyboard for inputting characters and the like, has been widely used. However, in a notebook computer, a stick type pointing device (stick pointer) attached to a keyboard instead of a mouse has become widespread. With the miniaturization of notebook computers, stick pointers have also been required to be thinner, and the feel of the stick pointers has also been diversified due to differences in human preferences.

FIG. 10 shows a configuration of a conventional notebook-type personal computer using a stick pointer. A stick pointer 11 is arranged in a keyboard (not shown), and inputs a figure or the like by operating a stick 11a with a finger. . The stick 11a shows a change in resistance value corresponding to the applied force, which is converted into an electric signal and processed by a circuit called a controller 11b. Then, the data is sent to the personal computer main body 12, and the personal computer main body 12 displays a display-symmetrical graphic or the like on the display device 13.

[0004]

However, the required operation weight and the like of the stick pointer differ depending on the type of the stick pointer, and there are cases where the pointing cursor cannot be moved on the screen of the display device as intended when operated with a finger. there were. Also, each operator has an operability habit. For example, when drawing a circle or the like on a screen with a stick pointer, it is difficult to draw an intended perfect circle as shown by a solid line A in FIG. As shown, I could only draw a distorted circle. Even so, even with the familiarity of drawing a circle that is close to a perfect circle, it was difficult to move the cursor again as if feeling uncomfortable when using a personal computer of a different model. Of course, not only in a circle, but also in a normal use such as moving a cursor in a certain direction, for example, if the angle is shifted and the moving speed is fast, it goes too far in a state shifted from the target position,
It is necessary to return the cursor position again, and the cursor cannot be moved as expected, leading to a significant decrease in work efficiency.

Moreover, once set, the contents of the signal processing cannot be changed by the user (operator or the like), and if a stick pointer with poor operability is used for a long time, the fatigue of the operator becomes large. Became a cause of stress. Further, even if the characteristics of the stick pointer change due to aging, there is no means for correcting this later. In addition, characteristics of devices such as a stick pointer vary during manufacturing, and it is troublesome to correct the characteristics.

In the present invention, therefore, the operator's operability is quantitatively converted into data beforehand, and this data is stored in a personal computer, and is stored when the operator inputs an arbitrary figure using a stick pointer. An object of the present invention is to make it possible to move a cursor as intended by correcting data input by data.

[0007]

In the pointing cursor calibrating apparatus of the present invention, the microcomputer has a program memory storing a calibrating program, and the cursor control means is constituted by the calibrating program.

Further, according to the pointing cursor calibration method of the present invention, a reference pattern is displayed on a display device, a pointing device is operated so that the pointing cursor moves along the reference pattern, and the pointing device at that time is operated. Calculating a correction coefficient from a comparison between the data of the operation input and the data of the reference pattern, and displaying an arbitrary pattern on the display device, the arbitrary coefficient input by the pointing device using the correction coefficient. The pattern data is corrected and displayed on the display device.

Further, in the pointing cursor calibration method according to the present invention, the correction coefficient is represented by a difference or a ratio at each predetermined angle between the data of the operation input of the pointing device and the data of the reference pattern.

In the pointing cursor calibration method according to the present invention, the difference or ratio in the X-axis direction and the Y-axis direction is used as the correction coefficient.

In FIG. 1, a personal computer (referred to as a personal computer) main body 1 has a stick pointer 2 which is a pointing device for inputting a figure or the like,
The display device 3 and a keyboard 4 for inputting characters and the like are connected by a bus 5. The personal computer 1 has a CPU 1a, a program memory 1b, a nonvolatile correction coefficient storage memory 1c, an image pattern memory 1d, and the like. The program memory 1b quantitatively converts the operability of the operator into data and calculates a correction coefficient. When an arbitrary graphic pattern is input, the input data is corrected by the correction coefficient and displayed. A program for controlling the position of the pointing cursor so as to be displayed on the device is stored. The correction coefficient memory 1c stores the calculated correction coefficient.

The image pattern memory 1d stores reference pattern data indicating a figure such as a perfect circle, which is used to quantitatively convert the operability of the operator into data. Then, the characters, figures, and the like processed by the personal computer 1 are displayed on the display screen 3b via the image output circuit 3a.

The stick pointer 2 is disposed substantially at the center of the keyboard 4 and has an operation stick 2a, A / D conversion circuits 2b and 2c, and a controller 2d. Then, a figure or the like is input by operating the stick 2a with a finger. When a lateral force is applied to the stick 2a, a change in resistance value corresponding to the force is converted into an electric signal, which is output in two systems in the X-axis direction and the Y-axis direction.
The signals are converted into digital signals by the D converters 2b and 2c. Then, it is processed by a circuit called a controller 2 d and sent to the personal computer main unit 1 via the bus 5.

Here, the operator's operability habit is what is called an operator's habit or propensity at the time of operation, and there is a propensity to the operation direction and a propensity to the operation weight. The propensity for the operation direction is, for example,
The propensity to tilt when a straight line is drawn in the X-axis direction or the Y-axis direction. The propensity to the operation weight is different from the operation weight depending on the operation direction, and for example, becomes an ellipse when trying to draw a perfect circle. It is a propensity.

Therefore, the pointing cursor calibration method of the present invention is based on the case where a correction coefficient is obtained based on data indicating such a tendency of the operator and stored in a personal computer, and the cursor is moved by the stick pointer 2 by the operator. In accordance with the stored correction coefficient, the input data is corrected to control the position of the pointing cursor so that the cursor can be moved as intended, for example, a circle close to a perfect circle can be drawn on the screen. To

First, in order to check the operability with respect to the operation weight, in step 1 (hereinafter referred to as S1) of FIG. 2, the operator issues a calibration command in a predetermined format for obtaining an operation weight correction coefficient. Input using the keyboard 4. Then, a program for quantitatively converting the operability stored in the program memory 1b into data is started, and, for example, graphic data for drawing a perfect circle stored in the image pattern memory 1d is displayed on the display device 3. Send (S2). With this data, a perfect circle pattern C as shown in FIG. 3 is displayed on the display screen 3b. At the same time, a message such as "Please move the pointer in the direction of the arrow in the figure" appears on the display screen 3b, and the operator operates the stick pointer 2 to start moving the cursor (S3).

Until the cursor is rotated once and the end button is pressed (S4), the CPU 1a continues to input the X-axis value Xi and the Y-axis value Xi continuously input by the stick pointer 2 according to the calibration program. Are read at predetermined intervals, for example, and stored in the image pattern memory 1d (S5, S6). Then, the stored values Xi and Y
i is read and a point Pi corresponding to Xi and Yi is displayed on the display screen 3b (S7). This operation is continued while the values in the X-axis direction and the Y-axis direction change (S8). Then, when the cursor makes one rotation, a distorted circular pattern D including the operability to the operation weight of the operator as shown in FIG. 4 appears on the display screen 3b.

Then, in S4, when the cursor has made one rotation and the end button has been pressed, then the center point (origin) of the perfect circle C is obtained.
A distance p between a straight line OPi connecting O and the point Pi, and a straight line OPi
The angle θi between the angle θi and the X-axis is obtained (S9), and the distance q of the straight line OQi with respect to the angle θi obtained from the data of the reference pattern already stored in the image pattern memory 1d is compared with the difference (p− q) or the ratio (p / q) is calculated (S10). Then, the difference or the ratio is stored in the memory. This difference or ratio becomes a correction coefficient indicating the operability in the operation direction of the operator.
The propensity for operation weighting in all directions of 60 degrees can be understood. Then, the correction coefficient is stored in the correction coefficient storage memory 1c, and the calculation of the correction coefficient ends (S12).

In S10 of FIG. 2, since the angles θi are not always equal, the difference or ratio may be calculated after obtaining the distance p at every predetermined angle interval by a complement method or the like. In S10, instead of calculating the difference or ratio with the reference pattern, the difference or ratio with the circle having the average radius of the input pattern may be calculated.

Further, as shown in FIG. 5, S9 in FIG.
Instead of S10, the maximum value Xmax and the minimum value Xmin in the X-axis direction and the maximum value Ymax and the minimum value Ym in the Y-axis direction
in (S13), and the difference or ratio between the maximum value and the minimum value of the reference pattern and the maximum value and the minimum value of the reference pattern may be calculated (S14), and may be used as the correction coefficient.

Next, a description will be given of a method of obtaining the correction coefficient by converting the operability tendency to the operation direction into data. The operator inputs a calibration command in a predetermined format for obtaining a correction coefficient in the operation direction from the keyboard 4 (S21).
Thereafter, the flow from S22 to S28 is performed from S2 to S in FIG.
Since the flow is exactly the same in correspondence with the flow up to 8, the detailed description is omitted, but the reference pattern displayed on the display screen in S22 is a figure on a cross as shown in FIG. This figure draws straight lines in the horizontal and vertical directions. FIG.
An example of the figure of the pattern input along the reference pattern shown in FIG.

Then, in S24, when the cursor is rotated once and the end button is pressed, next, four sides extending to four regions of a plus region and a minus region in the X-axis direction, and a plus region and a minus region in the Y-axis direction. To find out the slope of
The data is grouped separately for each of the four sides (S29), and the average inclination θx ₊ with respect to the X axis in the positive region in the X axis direction.
When the average inclination θx in the minus region _- and is calculated (S30), then the average slope [theta] y ₊ for the Y-axis in the positive region of the Y-axis direction, the average slope of minus region [theta] y _- and it is calculated (S30). Then, these inclination angles are stored in the correction coefficient storage memory 1c as correction coefficients in the form of a matrix. As a method of obtaining a correction coefficient from θx and θy, for example, when U and V are coordinate values in the X direction and the Y direction after correction, the correction coefficient is obtained by Expression 1.

(Equation 1) The inclination angle obtained here indicates a habit of drawing a straight line.

Next, when inputting an arbitrary figure by moving the cursor during use, for example, the stick pointer 2 is operated. At this time, a mouse having a correction function for correcting the position of the pointing cursor is used. The driver is always working and the correction coefficient memory 1c
Is read out. Then, the data input by the stick pointer 2 is corrected by the correction coefficient, and the position of the pointing cursor is calibrated based on the corrected data.

FIG. 9 is a flowchart for correcting data input by the stick pointer 2 using a correction coefficient. First, a state of waiting for an interrupt (S41).
, The operation starts when a force is applied to the stick pointer 2 in the X-axis direction and the Y-axis direction, and the X-axis output (x) and the Y-axis output (y) are read (S42, S43). Up to this point, it is the same as in normal use. Next, coordinate conversion is performed in S44. Here, coordinate conversion is performed using the operability for the operation direction, and the position (U, V) at the new coordinates is obtained. Here, M is a correction matrix, and the inclination angles θx and θy obtained in FIG. 6 are used.

Next, at step S45, the moving speed Vx of the cursor in the X-axis direction and the moving speed Vy of the Y-axis direction are obtained. Here, θ = tan ⁻¹ (V / U), Vx = k · AJ (θ
i) · U, Vy = k · AJ (θi) · V, where k is a reference conversion coefficient and AJ (θi) is a speed correction coefficient.
Then, the cursor moving speed obtained in S45 is displayed on the display device 3.
To the cursor display routine in the driver (S4)
6). As described above, the moving direction and the moving speed of the cursor are corrected to form the position of the cursor.
