Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointing device, and more particularly to an apparatus for performing pointing by using finger pressure.

[0002]

2. Description of the Related Art In a personal computer, a CR
It may be necessary to move the cursor displayed at T to a predetermined position and input data regarding the position (hereinafter referred to as “pointing”). For example, when using software having a graph function, it is necessary to frequently specify the starting point and ending point of a figure. Further, even in software having a word processor function, a position for inputting a character or the like may be designated, or a display position of a choice may be designated when a desired choice is selected.

In order to smoothly perform this position designation operation,
The mouse or keyboard arrow keys are used. Especially when a mouse is used, the cursor can be arbitrarily moved not only in the up / down direction and the left / right direction but also in the oblique direction. Further, since the data relating to the position can be easily input by clicking the button attached to the mouse, the operation becomes quicker than the pointing using the arrow keys.

Further, in the case of inputting with a mouse, the cursor moves in the same direction in accordance with the movement of the mouse, so that an operation feeling closer to the human sense can be obtained.

For these reasons, the mouse is widely used as a simple pointing device in a personal computer.

[0006]

However, the conventional pointing device as described above has the following problems.

Since the mouse is operated by moving it on a plane in any direction such as up, down, left and right, a space for operating the mouse is required near the personal computer. Usually, such a space is provided in a corner of a desk where a personal computer is installed. Therefore, the space for office work such as document processing is limited.

Further, since the space for operating the mouse is limited, one operation of the mouse is not enough to move the cursor to a distant position, and the mouse operation needs to be repeated several times. In this case, there is a gap between the movement of the cursor and the human sense of operation.

An object of the present invention is to solve the above problems and to provide a pointing device which does not require an operation space and can obtain an operation feeling closer to that of a human.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A pen grip type input device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a pen grip type input device. The detection means 2 is attached to a writing instrument. The detection means 2 is provided with sensor parts 4, 6 and 8 to measure the pressure of three fingers applied to the writing instrument.
The sensor part 4 measures the pressure of the middle finger, the sensor part 6 measures the pressure of the index finger, and the sensor part 8 measures the pressure of the thumb.

The pressure measured by the sensor parts 4, 6 and 8 is converted into an electric signal and given to the analyzing means 10. The analysis means 10 analyzes the given electric signal and calculates the moving direction and moving distance of the cursor.

The moving direction and moving distance of the cursor calculated by the analysis means 10 are given to the display means 12. The display means 12 has a screen capable of displaying a cursor, and changes the position of the cursor based on the moving direction and the moving distance given from the analyzing means 10. The confirmation signal generating means 16 is
It is for outputting a confirmation signal 16 for confirming the cursor position. When the cursor displayed on the display means 12 is at a desired position, the user of the pen grip type input device operates the confirmation signal generating means 16 to generate the confirmation signal 16 for confirming the cursor position. Let When the confirmation signal 16 is generated, the output means 18 reads the data relating to the cursor position and, at the same time, outputs this data to other means, if necessary.

A specific structure of the detecting means 2 will be described with reference to the drawings. FIG. 2 shows a pen grip which is the detection means 2. The pen grip 22 includes a triangular prism-shaped support 24 and a support 24.
It is composed of magnetic sensors 28a, 28b, 28c and a function switch 29 mounted above.

The support 24 is hollow so that it can be attached to a writing instrument 26 such as a ballpoint pen, felt-tip pen, pencil or fountain pen. The magnetic sensors 28a, 28b, 28c are mounted on the three different outer surfaces of the support 24, one each. The magnetic sensor 28a is, as shown in FIG. 3, a magnetic resistance element 30 covered with a silicon rubber 32 and a magnet sheet 34. Finger pressure is applied in the direction of arrow Y1. The magnetic sensors 28b and 28c also have the same structure as the magnetic sensor 28a.

The function switch 29 which is the confirmation signal generating means 16 is provided on the same surface as the magnetic sensor 28b of the support 24 and has the same structure as the magnetic sensor 28a shown in FIG.

FIG. 4 shows an example of a hardware configuration when the functions of the blocks shown in FIG. 1 are realized by using a CPU. The CPU 40, which is the analysis means 10, has a pen grip 22,
ROM 42, RAM 44, keyboard 46, and CRT 48 are connected. The CPU 40 controls each unit according to the program stored in the ROM 42.

The programs stored in the ROM 42 or the RAM 44 include a program that defines a method for calculating the moving direction and the moving distance of the cursor based on the finger pressure detected by the magnetic sensors 28a, 28b, 28c. . RA
The M44 stores outputs from the magnetic sensors 28a, 28b, 28c and the like. The keyboard 46 is used to input a command when the command input is required to proceed the pointing work. The CRT 48, which is a display means, displays a screen (a cursor is displayed) necessary for advancing the pointing work.

Next, a pointing method using the pen grip type input device will be described. On the screen 50 of the CRT 48 of the personal computer, as shown in FIG.
The cursor 52 is displayed. The cursor 52 moves in the screen 50 in any direction such as up, down, left, and right depending on the strength of the pressure applied to each magnetic sensor 28a, 28b, 28c.

A person who uses the pen grip type input device to perform pointing (hereinafter referred to as “input person”) attaches the pen grip 22 to a writing instrument, and the portion of the pen grip 22 is naturally touched with the middle finger, the index finger, and the thumb. Grip with great strength. At this time, the middle finger touches the magnetic sensor 28a, the forefinger touches the magnetic sensor 28b, and the thumb touches the magnetic sensor 28c.

In this state, the pen grip 22 is naturally gripped (hereinafter, referred to as "holding state"), and therefore the finger pressure applied to the magnetic sensors 28a, 28b, 28c is weak. Therefore, the cursor 52 on the screen 50 of the CRT 48 does not move.

Next, the input person intentionally applies a strong pressure to draw a line in the moving direction of the cursor 52 while holding the writing instrument with the pen grip 22 in his hand. In addition,
It is not necessary to actually move the writing instrument, just adjust the pressure applied to the three fingers as if drawing a line in that direction.

For example, when the cursor 52 is moved to the right (the direction of arrow X), a relatively strong force is applied to the thumb, and when the cursor 52 is moved to the left, it is relatively moved to the index finger. Apply strong force. Downward (direction of arrow Y)
When it is moved to, the relatively strong force is applied to the thumb and forefinger, and the force of the middle finger becomes relatively weak. When moving upward, it is almost opposite to when moving downward.

Since this state is a state in which the magnetic sensors 28a, 28b, 28c are intentionally applied with pressure to perform pointing (hereinafter referred to as "pointing state"),
A strong finger pressure is applied to the magnetic sensors 28a, 28b, 28c.
Therefore, the cursor 52 moves in the direction according to the pressure of the three fingers.

The finger pressure detected by the magnetic sensor is converted into a voltage value as follows. Magnetic sensor 28a, 28
The b and 28c first detect the finger pressure as an electric signal.
The electric signals output from the magnetic sensors 28a, 28b, 28c are
It is digitally processed using the adapter 60 shown in FIG. 6 and converted into a voltage. The adapter 60 includes amplifiers 61a, 61b, 61c,
Analog multiplexer 62, clock control circuit 64, A /
It is composed of a D conversion circuit 66 and a parallel / serial conversion circuit 68.

The amplifiers 61a, 61b, 61c perform analog processing such as offset and gain adjustment, and the magnetic sensor 28
The outputs of a, 28b and 28c are converted into voltage changes. Analog multiplexer based on clock signal from clock control circuit 64
The magnetic sensors 28a, 28b, 28c entering 62 are sequentially selected, and the output voltages of the amplifiers 61a, 61b, 61c are applied to the A / D conversion circuit 66.

The A / D conversion circuit 66 holds the voltage for a fixed time by the clock (sampling pulse) and outputs the input voltage value as a digital signal. The parallel / serial conversion circuit 68 is the magnetic sensor selected at that time.
28a, 28b, 28c and voltage value are converted to serial data and C
Send to PU40. The CPU 40 stores the received data in the RAM 44 for each of the magnetic sensors 28a, 28b, 28c.

An analysis method by the CPU 40 will be described with reference to FIGS. 7 and 8. 7 and 8 are a series of flowcharts showing the procedure for calculating the moving direction and moving distance of the cursor. → in FIG. 7 continues to → in FIG.
The → in FIG. 8 follows the → in FIG. 7.

In the initial state, the cursor 52 is positioned and displayed in the center of the screen (step S
1). The cursor position on the screen is represented by coordinates (G _X , G _Y ), where the upper left corner is (0, 0) and the lower right corner is (639, 39).
9). The number in parentheses corresponds to the number of dots on screen 50. The movement from (0,0) to (1,1) is one dot to the right and one dot below.

The CPU 40 reads the data stored in the RAM 44 and reproduces the outputs (voltage values) of the magnetic sensors 28a, 28b, 28c. Reproduced magnetic sensor 28a, 28b, 28c
Output (voltage value) is classified into a holding state and a pointing state.

This distinction is made by setting the voltage value to a predetermined threshold value Vth.
It is performed by comparing with (step S2). When the voltage value exceeds the threshold value Vth, it is determined that the voltage value represents the pointing state. On the other hand, when the voltage value is below the threshold value Vth, it is determined that the voltage value represents the holding state.

In this embodiment, the threshold value Vth is set to 1.2 volts. Therefore, if the voltage value is less than 1.2 volts, it is classified into the holding state. The pointing condition is detected as a voltage change between 1.2 and 6 volts.

When the voltage value of one magnetic sensor exceeds the threshold value Vth, the pen grip 22 is in the pointing state even if the voltage values of the other magnetic sensors are below the threshold value Vth. To be judged.

In the analysis by the CPU 40, the following processing is performed on the voltage value indicating the pointing state. As for the movement of the cursor 52, the movement in the left-right direction and the movement in the up-down direction are basic movement units, and by combining these, the movement in the oblique direction is processed. Therefore, first, an analysis is performed on the horizontal movement and the vertical movement.

Therefore, the pressures (voltage values) applied to the magnetic sensors 28a, 28b and 28c are designated as P ₀ , P ₁ and P ₂ , respectively. That is, P ₀ is the pressure of the middle finger, P ₁ is the pressure of the index finger, and P ₂ is the pressure of the thumb. Further, the pressure difference between the middle finger and the index finger is D ₀₁ , the pressure difference between the index finger and the thumb is D ₁₂ , and the pressure difference between the middle finger and the thumb is D _02, and D ₀₁ = P ₀ −P ₁ D ₁₂ = P ₁ −P ₂ D ₀₂ = P ₀ −P ₂ . These values are calculated (step S3).

A method of analyzing the lateral movement will be described. The lateral movement is obtained from the relative force relationship between the pressure P _{1 of} the index finger and the pressure P ₂ of the thumb.

D ₁₂ is a value obtained by subtracting the pressure (voltage value) of the thumb from the pressure (voltage value) of the index finger. If this value is a positive number (D ₁₂ > 0), it is determined that a relatively strong force is applied to the index finger and a signal for moving the cursor 52 to the left is given. On the other hand, if D ₁₂ <0, it is determined that a relatively strong force is applied to the thumb and a signal for moving the cursor 52 to the right is given. Furthermore, D ₁₂
= 0, the forefinger and thumb are even, and the cursor
It is determined that 52 is not moved in the left and right directions (step S4).

Further, the moving distance in the left-right direction is obtained as follows. RABS (D ₁₂ ) is the absolute value of D ₁₂ rounded to the nearest whole number and expressed as an integer.
For example, if P ₁ is 2.8 volts and P ₂ is 3.6 volts, then D ₁₂ is -0.8 volts (minus 0.8 volts).
become. This absolute value is 0.8, and RABS (D ₁₂ ) obtained by rounding off the decimal point is 1.

When the moving distance of the cursor 52 is represented by the number of moving dots on the screen 50, RABS (D ₁₂ ) is the number of moving dots in the horizontal direction. In the above example, D ₁₂ is -0.
If it is 8 volts, RABS (D ₁₂ ) will be 1, so
The number of moving dots becomes 1. Also, in this example, D ₁₂ <0, so the cursor 52 moves one dot to the right (step S5).

Number of dots moved in the left-right direction RABS (D ₁₂ )
Is added to or subtracted from the X coordinate at that time. If the cursor is moved to the right, RABS (D ₁₂ ) is added (step S7). If the cursor is moved to the left, RABS (D ₁₂ ) is added.
₁₂ ) is subtracted (step S8).

Next, a method for obtaining the vertical movement distance will be described. The vertical movement is obtained based on the relative force relationship between the pressure P ₀ of the middle finger and the pressure P ₁ or P ₂ of the index finger or thumb.

D ₀₁ is a value obtained by subtracting the pressure (voltage value) of the index finger from the pressure (voltage value) of the middle finger. D ₀₂ is a value obtained by subtracting the pressure (voltage value) of the thumb from the pressure (voltage value) of the middle finger. When the sum of D ₀₁ and D ₀₂ is greater than 0 (D ₀₁ + D
₀₂ > 0), it is determined that a signal for moving the cursor 52 upward is given. On the other hand, D ₀₁ + D ₀₂ <0
If so, it is determined that a signal for moving the cursor 52 downward is given. Further, if D ₀₁ + D ₀₂ = 0, it is determined that the cursor 52 is not moved in the vertical direction (step S9).

Further, the moving distance in the vertical direction is obtained as follows. After obtaining the average value (D ₀₁ + D ₀₂ ) / 2 of D ₀₁ and D ₀₂ , the absolute value of this average value is rounded to the nearest whole number and expressed as an integer RABS ((D ₀₁ + D 02
₀₂ ) / 2). For example, if P ₀ is 1.3 volts, P ₁ is 2.8 volts, P ₂ is 3.6 volts, and D ₀₁ and D ₀₂ are -1.5 volts and -2.3 volts, respectively. , And the average value is {−1.5 + (− 2.3)} / 2 = −1.
The absolute value of the average value is 1.9. RABS obtained by rounding off below the decimal point of this absolute value
((D ₀₁ + D ₀₂ ) / 2) is 2.

RABS ((D ₀₁ + D ₀₂ ) / 2) is the number of vertically moving dots. In the example above, RABS ((D
_{Since 01} + D ₀₂ ) / 2) becomes 2, the number of moving dots becomes 2. Further, in this example, (D ₀₁ + D ₀₂ ) / 2 <0, so the cursor 52 moves downward by 2 dots (step S10).

Number of vertically moving dots RABS ((D ₀₁
+ D ₀₂ ) / 2) is added to or subtracted from the Y coordinate at that time. If the cursor moves up, RABS ((D ₀₁ +
D ₀₂ ) / 2) is subtracted (step S12), and if the cursor moves downward, RABS ((D ₀₁ + D ₀₂ ) /
2) is added (step S13).

A method of obtaining the movement distance in the oblique direction will be described. The diagonal movement is obtained by combining the horizontal movement and the vertical movement. For example, P ₀
Is 1.3 volts, P ₁ is 2.8 volts, and P ₂ is 3.6 volts. The direction of movement and the distance traveled in the left-right direction are the sign of D ₁₂ (+, −, 0) and RABS (D ₁₂ ), respectively.
Since it is given by, the movement is 1 dot to the right.
On the other hand, the vertical movement direction and movement distance are D
₀₁ + D ₀₂ sign (+,-, 0) and RABS ((D 0 ₁ + D
_Since it is given by ₀₂ ) / 2), it will be moved by 2 dots in the downward direction.

A combination of these movements is an oblique movement. Therefore, the cursor 52 moves one dot to the right and two dots to the right. Therefore, by maintaining this state, the result is a straight line in the right slanting downward direction (the number of moving dots in the X direction). ² + (number of moving dots in Y direction) ² will be moved by the square root.

The above calculation is performed at a speed according to the processing capacity of the CPU 40 and the like. In this embodiment, it is performed at a rate of 50 times per second. Therefore, the position of the cursor 52 is also determined 50 times per second, and the cursor 52 on the screen 50 moves accordingly (step S14). Magnetic sensor 28
While the pressure is continuously applied to a, 28b, and 28c, the above calculation and the movement of the cursor 52 are continued. When the cursor 52 reaches the desired position, the pressure applied to the magnetic sensors 28a, 28b, 28c is lowered to the level of the holding state.

Next, a method of determining the cursor position of the cursor 52 that has reached the desired position will be described. The cursor position is determined by using the input confirmation function of the function switch 29.

The input confirmation function is a function for confirming the cursor position of the cursor 52 displayed on the screen 50 of the CRT 48 at that time. Press the function switch 29 with your index finger for a long time to apply pressure. By this operation, the function switch 29 outputs an electric signal which is the confirmation signal 16 (step S16). This electrical signal is digitally processed by the adapter 60 and converted into a voltage value, as in the case of the electrical signal output from the magnetic sensors 28a, 28b, 28c. This allows the CPU 40 to go from 1.2 volts to 2
A voltage of about 1 volt can be applied within a predetermined time (for example, 1 second).
When only the number of times of detection is detected, the cursor position is determined (step S17).

When designating the cursor position, normally,
The above signals alone are sufficient. However, different situations may require different types of deterministic signals. For example, in general software, double-clicking may be required to specify a desired option. The function switch 29 has the same function as this. That is, when the function switch 29 is momentarily pressed twice with the index finger and the CPU 40 detects a voltage of 1.2 V or more twice within a predetermined time (for example, one second), the double-click function works. It is like this.

Although the magnetic sensors 28a, 28b, 28c are used as the sensors for detecting the finger pressure in the above-mentioned embodiment, they are static like a piezoelectric body such as a piezoelectric ceramic, a pressure conductive rubber, or a condenser microphone. A sensor that uses capacitance or electromagnetic induction may be used. Furthermore, a different sensor may be used for each finger.

In the above embodiment, the pen grip 22
Although three magnetic sensors 28a, 28b, 28c are provided in the above, four or more magnetic sensors may be provided. Shape of pen grip 22 and magnetic sensor 28
The installation positions of a, 28b, and 28c are not limited to those in the above embodiment.

Further, in the above embodiment, the pen grip
Although 22 is attached to the writing instrument, the pen grip 22 may be integrated with the writing instrument.

In the above embodiment, the function switch 29 has the input confirmation function, but the function provided in the function switch 29 is not limited to this function. For example, the following cursor movement function may be used. That is, the function switch 29
When the CPU 40 momentarily and weakly presses with the index finger and the CPU 40 detects a voltage of about 1.2 to 2 V for about 0.5 seconds, the cursor 52 moves to the left end of the line and the function switch 29 is turned on. When the CPU 40 momentarily strongly presses it and the CPU 40 detects a voltage of 3 V or more for about 0.5 seconds, the cursor 52 moves to the right end of the line.

In the above embodiment, the input confirmation function is selected and executed by operating the function switch 29. However, the input confirmation is performed by operating the function switch 29 and arbitrary magnetic sensors 28a, 28b, 28c at the same time. The function may be selected and executed. For example, by pressing the function switch 29 with the index finger, the CPU 40
Magnetic sensor of thumb while giving a voltage value of 2 volts or more
When a voltage value of 5 V or more is applied continuously from 28c for 0.5 seconds or more, the double click function may be activated.

Therefore, since it is not necessary to provide a special operation space, the space for office work such as document processing is not restricted, and the work space can be effectively used.

Further, the cursor can be moved to a distant position only by increasing the pressure of the finger applied to the pen grip. Therefore, the cursor can be moved to all the cursor positions with one operation.
