BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input device for a computer, and more particularly to a device that enables input of three-dimensional data.

[0002]

2. Description of the Related Art As a data input device for a computer,
In addition to keyboards, pointing devices such as mice and digitizers are widely used. FIG. 15 is an explanatory diagram of a usage state of the mouse C, which is an example of a pointing device. As shown, mouse C is computer B
Is connected to the data input section of the mouse via a predetermined mouse interface. Then, by the software on the computer B side, the pointer displacement amounts in the horizontal (X-axis) direction and the vertical (Z-axis) direction on the screen are respectively measured on the desk in the front-back (Z-axis) left-right (X-axis) direction. It corresponds to the movement amount of. At the time of use, the operator moves the mouse body in a desired direction. In response to this, the pointer on the screen of the computer B is displaced. As described above, currently, the screen operation by the mouse C is limited to two-dimensional operation. This is also the case when other similar data input devices such as digitizers are used.

[0003]

By the way, in the screen operation of the computer B, in a plurality of simultaneous processes such as a multitask process and a multiwindow process, as shown in FIG. 16, the display screens a and b to be processed are displayed. , C are assumed to be sequentially stacked. In this case, in order to open the target display screen, it is necessary to open sequentially from the higher order display screen. Therefore, when managing many display screens, not only the operation becomes complicated, but also an operation error easily occurs. This is because the conventional data input device can only input two-dimensional data, and the software provided has to correspond to it.

On the other hand, three-dimensional data input is generally used in CAD (image forming support system by computer) used in construction machine design and the like. However, since the conventional data input device can only support two-dimensional data input, the functions provided by CAD cannot be fully exerted, which is inconvenient in operation.

In view of the above background, an object of the present invention is to solve the above problems.
It is to provide a data input device having a simple structure that enables three-dimensional data input to a computer.

[0006]

A three-dimensional data input device of the present invention for solving the above problems detects a ball body rotatably arranged in the apparatus body and the amount of rotation given to this ball body. A rotation detecting sensor, a displacement amount data generating means for generating displacement amount data of a pointer in one plane from the rotation amount detected by the rotation detecting sensor, and an angular velocity around an axis having a predetermined angle with respect to the plane. An gyro that detects it and converts it into an angular velocity signal,
At least a rotation amount data generating means for generating rotation amount data of a pointer around the axis or around another axis having a constant inclination angle with respect to the axis based on the angular velocity signal, the displacement amount data and the rotation amount. It is configured to output at least one of the data in a predetermined data format.

The rotation amount data generating means has a temperature correction means for deriving a temperature coefficient value corresponding to the ambient temperature of the angular velocity meter and correcting the converted angular velocity signal based on the temperature count value. And

Another three-dimensional data input device for solving the above-mentioned problems is arranged on a plurality of axes having predetermined angles,

And a rotation amount data generating unit for generating the rotation amount data, and is configured to output the rotation amount data in a predetermined data format. In this case, since the number of axes is three-dimensional, it is preferable that the number of axes is three orthogonal to each other. However, the number can be arbitrarily set because coefficient calculation correction is possible.

As a preferred mode of this configuration, the rotation amount data generating means is provided with means for converting each of the angular velocity signals into a digital signal whose amplitude value is averaged within a prescribed time. More preferably, further, a coordinate conversion unit that converts the converted digital signal into a coordinate value signal, a signal branch unit that branches the coordinate value signal converted by the coordinate conversion unit into at least two, and this signal branch unit. A filter unit that removes different frequency components from each of the branched signals branched by, a signal combining unit that combines the branched signals that have passed through this filter unit, and the signals combined by the signal combining unit are integrated by angle integration. And means for generating angle data corresponding to the angular velocity signal, and each of the generated angle data is guided to the coordinate conversion unit as a conversion parameter of the coordinate value signal.

In order to make the angle data more accurate, the rotation amount data generating means is configured such that when the change in the angular component contained in the angular velocity signal is within the area preset as the dead zone, the amplitude of the low frequency component is increased. A correction means for correcting the value, that is, the offset component is provided so that the harmful offset component can be sequentially canceled.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a three-dimensional data input device of the present invention will be described in detail below with reference to the drawings.

(First Embodiment) FIGS. 1A and 1B are explanatory views when the present invention is applied to a three-dimensional mouse. FIG. 1A is a front sectional view showing the internal arrangement, and FIG. 1B is a side sectional view. Is. The three-dimensional mouse A is composed of a sensor unit 1 and a calculation unit 2. The sensor unit 1 includes a rotatable ball body 4, two rotary encoders 5 used as rotation detection sensors, inside a mouse body 3 that is small enough to be held by a hand.
6, a gyro 7 used as an angular velocity meter, and two switches 8 and 9 are arranged.

The ball body 4 is arranged so that a part thereof is exposed from an opening 3a formed in the bottom of the mouse body 3, and the exposed portion contacts the mouse pad 18, whereby the mouse body 3 is moved. It is designed to rotate in conjunction with. The rotary encoders 5 and 6 are arranged so as to be in constant contact with the surface of the ball body 4 in two horizontal axis directions (front and rear, left and right) orthogonal to each other, and output signals corresponding to the rotation amount of the ball body 4 on each axis. It is supposed to do. The gyro 7 is arranged on a third axis (vertical direction) orthogonal to the two axes and outputs a signal corresponding to the rotation amount of the mouse body 3. The two switches 8 and 9 are interlocked with the operation buttons 10 and 11 arranged on the upper surface of the mouse body 3, and when a corresponding operation button is pressed, a selection signal indicating that is output.

In the rotary encoders 5 and 6, the rotary slit provided on the same rotary shaft as the roller in contact with the ball body 4 rotates in conjunction with the rotation of the ball body 4 and turns the state when the light is blocked. The rotation amount of the ball 4 is detected by a photo sensor, converted into a rotation signal (pulse signal), and output.

The gyro 7 is not particularly limited as long as it can detect the angular velocity with high accuracy.
For example, it is more preferable to use a piezoelectric vibrating gyro (for example, a piezoelectric vibrating gyro manufactured by Murata Manufacturing Co., Ltd. (ENC-05D)). Since this piezoelectric vibration gyro is small and lightweight and can be mounted in the mouse body 3 and has high mass productivity, it is expected that the manufacturing cost will be significantly reduced.

The sensor unit 1 detects the amount of forward and backward movement of the mouse body 3 (the amount of rotation of the ball body 4) by the first rotary encoder 5 and outputs it as a rotation signal P1. The amount of movement (the amount of rotation of the ball body 4) is detected by the second rotary encoder 6 and output as a rotation signal P2. When the mouse body 3 rotates, this is detected by the gyro 7 and output as an angular velocity signal R. Then, these signals P1, P2, R are sent to the arithmetic unit 2 together with the selection signals S1, S2 corresponding to the switches 8, 9.

The arithmetic unit 2 is an analog interface 1.
2, a pulse interface 13, an output interface 14, a CPU 15, and a memory 16, and the driving power for the driving is supplied from the computer side through a power line integrated with the signal cable 17.

The analog interface 12 is an A / D converter for converting the angular velocity signal R detected by the gyro 7 into a digital signal, and a noise filter (bandpass filter) for removing DC components and high frequency noise components contained in the digital signal. Filter) and the output of the noise filter to the CPU
An amplifier for amplifying 15 input levels is provided.

The pulse interface 13 is a waveform shaping circuit for shaping the pulse signals P1 and P2 detected by the rotary encoders 5 and 6, and a CP for the shaped pulse signal.
An amplifier for amplifying the input level of U15.

The CPU 15 is, for example, a one-chip microprocessor, and exchanges information with the memory 16 to form a required function in the arithmetic unit 2. Memory 1
Reference numeral 6 includes a ROM that stores a processing program that the CPU 15 reads and executes, and a RAM that stores the processing result of the CPU 15. FIG. 2 shows an example of functional blocks formed in the calculation unit 2 by the cooperation of the processing program in the memory 16 and the CPU 15. In addition, in FIG.
The / D converter 1 and the noise filter 122 are blocks included in the analog interface 12 described above,
Further, details of other interfaces and amplifiers in the preceding stage of the CPU 1 are not shown.

Referring to FIG. 2, the pulse signal P input through the pulse interface 13 is input to the arithmetic unit 2.
Pulse counter 151 for counting 1 and P2
And a distance data generation unit 152 that generates displacement amount of the pointer on the screen, that is, distance data based on the counted number of pulse signals. This corresponds to the two-dimensional data input similar to the conventional one. The calculation unit 2 also detects a rotation amount of the pointer on the screen, that is, a dead zone for obtaining the angle data from the angular velocity signal R detected by the gyro 7 and processed through the A / D conversion unit 121 and the noise filter 122. A processing unit 153, an integration circuit 154, and an angle data generation unit 155 are formed.

The dead zone processing section 153 determines that the mouse body 3 is not rotating, that is, is stopped within the area preset as the dead zone. If it is stopped, drift correction and origin correction are performed, and processing for forcibly returning the relative angle to the origin (zero value) is performed. The integration circuit 154 integrates the signal that has passed through the dead zone processing unit 153 for a prescribed time and outputs it as angle information. The angle data generation unit 155 corresponds the angle information output from the integration circuit 154 to the angular velocity signal. It is converted into angle data.

The arithmetic unit 2 further synthesizes the selection signals from the switches 8 and 9, distance data based on the pulse signals P1 and P2, and angle data based on the angular velocity signal R together with the output interface to be used, A data output unit 157 that outputs as three-dimensional data is formed. This three-dimensional data is input to the computer B via the signal cable 17 shown in FIG.

Since the gyro 7 is sensitive to temperature, temperature correction means is provided so as not to affect the calculation result even if the angular velocity signal R fluctuates due to temperature change. The temperature correction means obtains actual data for temperature changes in advance and creates a correction table in the processing program, and detects when a temperature detection sensor (not shown) detects the temperature around the gyro 7. The necessary correction is added to the angular velocity signal based on the temperature and the correction table. The temperature detection sensor can be easily realized by incorporating a thermistor or the like in the calculation unit 2 so that the processing program can read the detected temperature of the thermistor at any time.

Since the three-dimensional mouse A is constructed as described above, when two-dimensional data input is desired for the computer B, the mouse body 3 is moved back and forth as shown in FIG. 3 (a). This can be done simply by moving to the left and right (Y axis) (Z axis). When the user wants to input three-dimensional data, the mouse body 3 is rotated by a required amount. Thereby, as shown in FIG. 3B, the gyro 7 detects the angular velocity and outputs the angular velocity signal R to the calculation unit 2. The calculation unit 2 generates the amount of rotation of the pointer on the screen, that is, angle data based on the angular velocity signal R, and inputs this to the computer B.

Next, another example of the operation mode of the three-dimensional mouse A will be described with reference to FIGS. 4 and 5. Figure 5 (a) shows
This is an example of a case where the amount of rotation about the screen Z axis is obtained by rotating the mouse body 3 while pressing the left operation button 10 in a stopped state. In this case, the selection signal S1 from the left switch 8 and the gyro 7 are sent from the mouse body 3.
And the angular velocity signal R are transmitted to the calculation unit 2.
The calculation unit 2 generates angle data from the angular velocity signal R and sends it to the computer B together with the selection signal S1 of the left switch 8. Computer B, as shown in FIG.
The display data on the screen is rotated by a predetermined amount based on this angle data.

FIG. 5B shows an example in which the amount of rotation around the Y-axis of the screen is obtained by rotating the mouse body 3 while pressing the right operation button 11 while the mouse body 3 is stopped. In this case, from the mouse body 3, the right switch 9
The selection signal S2 and the angular velocity signal R from the gyro 7 are sent to the calculation unit 2. The calculation unit 2 generates angle data corresponding to the angular velocity signal R and sends it to the computer B together with the selection signal S2 of the right switch 9.

FIG. 5C shows a case where the mouse body 3 is stopped and the left operation button 10 and the right operation button 11 are rotated while being pressed. At this time, the selection signal S1 for the left switch 8 and the selection signal S2 for the right switch 9 and the angular velocity signal R for the gyro 7 are sent from the mouse body 3 to the computing unit 2. The calculation unit 2 generates angle data corresponding to the angular velocity signal R, and sends the angle data together with the selection signals S1 and S2 of the left switch 8 and the right switch 9 to the computer BI. The computer B processes the received angle data around the X axis of the screen.

Further, the movement of the cursor on the screen (the X and Z directions of the screen) is controlled by operating the front, rear, left and right like the conventional mouse, and the Y axis direction, that is, the depth direction of the screen corresponds to the push button. You may let me. For example, as shown in FIG. 5D, when the mouse body 3 is moved back and forth while pressing the left operation button 10, the sensor unit 1 outputs the selection signal S1 of the left switch 8 and the pulses of the rotary encoders 5 and 6. The signals P1 and P2 and the angular velocity signal R of the gyro 7 are sent to the arithmetic unit 2. The calculation unit 2 calculates the angle data (0 degree) corresponding to the angular velocity signal R.
And distance data corresponding to the pulse signals P1 and P2 are generated, and these are sent to the computer B together with the selection signal S1 of the left switch 8. From the received data, the computer B determines that the mouse body 3 is moving forward and backward without rotating, and performs processing for enlarging and reducing the figure according to the movement amount of the mouse body 3 without performing rotation processing. I do.

The operation of the graphic data by the computer B is determined by how the input data from the three-dimensional mouse A is processed by the application, and the operation method of the three-dimensional mouse A is not always required. The operation method is not limited to the above. Further, in the above-mentioned three-dimensional mouse A, the mouse body 3 having two operation buttons is provided.
However, the number of operations is not limited to two, and for example, two operations can be performed by arranging a third operation button (not shown) on the left side surface of the mouse body 3 and arranging it on the upper portion of the mouse body 3. The buttons may be operated with the index finger and the middle finger, and the third operation button may be operated with the thumb. As a result, more information can be sent from the three-dimensional mouse A to the computer B.

As described above, according to the present embodiment, the three-dimensional mouse A simultaneously outputs three-dimensional data based on the movement amount and the rotation amount of the mouse body 3 and the signal based on the operation button. Compared with a conventional mouse that performs screen operations while being used together, more information can be sent to the computer B simply by operating the mouse body 3, and advanced screen operations can be performed with simple operations.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 shows the first
It is a block diagram which shows the example at the time of applying this invention to a three-dimensional mouse like the case of embodiment. The three-dimensional mouse 20 of this embodiment is configured by integrating a gyro unit 21, a mouse unit 22, and a main control unit 23.

The gyro unit 21 is formed by arranging the same gyros 22a, 22b and 22c as those used in the first embodiment on three axes, for example, X, Y and Z axes orthogonal to each other. The first gyro 22a corresponds to the roll angle (angle around the X axis), the second gyro 22b corresponds to the pitch angle (angle around the Y axis), and the third gyro 22c corresponds to the yaw angle (angle around the Z axis). It is a thing. Each gyro 22
The angular velocity signals output from a, 22b, and 22c are amplified by amplifiers (AMP) 23a, 23b, and 23c to signal levels that can be processed by the main control unit 23, respectively. The gyro unit 21 also includes a click button 24 for selecting three-dimensional data input and two-dimensional data input described later.

The mouse portion 22 is for allowing conventional two-dimensional data input, and is a rotatable ball body 2.
5, rotary encoders 26a and 26b that detect the amount of rotation of the ball 25, switches 27a and 27b that output a selection signal in conjunction with the left and right operation buttons described above, and a sub-control unit 28. The functions of the respective units except the sub control unit 28 are the same as the corresponding portions described in the first embodiment. The sub-control unit 28 is composed of a control IC and includes rotary encoders 26a and 26b and a switch 27.
The displacement amount data of the pointer in one plane is generated based on the output data of a and 27b. The operation of the mouse portion 22 is basically the same as that in the case of the first embodiment, and therefore a duplicate description will be omitted.

The main control section 23 comprises a one-chip CPU that operates at a predetermined clock and a memory section that stores a predetermined processing program, etc., and inputs it to a computer based on output data from the gyro section 21 and the mouse section 22. Generate two-dimensional data or three-dimensional data to be used. FIG. 7 shows a configuration example of functional blocks formed by the processing program and the CPU.

Referring to FIG. 7, the main controller 23 includes an A / D converter 231 for converting the angular velocity signals output from the gyros 22a, 22b, 22c into digital signals.
a, 231b, 231c are formed. Each A / D converter performs averaging processing when digitizing the input signal.

The outline of this averaging process is as shown in FIG. 8. First, when an angular velocity signal is input from the corresponding gyro (S101), it is read at high speed in a short division time period and numerical value addition is performed. Is performed (S102). Next, the number of times of reading is counted (S104), and when the count value reaches the specified value (S104: Yes), the numerical values in the specified time are averaged (S105). The specified time is
In this embodiment, it is 20 ms, and the division time for high-speed reading at this time is 17 μs. By this averaging process, the angular velocity signals having the envelope waveform as shown in FIG. 9A are averaged as shown in FIG. 9B, and when the angle integration is performed by the trapezoidal method described later, the accuracy as the angle data is obtained. However, it increases dramatically. The outputs of the A / D conversion units 231a, 231b, 231c are guided to the coordinate conversion unit 232.

The coordinate conversion unit 232 converts each digitized angular velocity component into, for example, a value in the Euler coordinate system. At that time, other angular velocity components or angle data fed back are used as conversion parameters. To use.
That is, the signal components on other axes are added. this is,
In the case of three-dimensional data, when the plane is rotated 360 with the plane having a constant inclination angle,
This is because the rotated data never returns to its original position, so it needs to be corrected. The coordinate conversion unit 232 outputs a roll angle component (which is referred to as a component because the error is included, the same applies hereinafter) Δα, a pitch angle component Δβ, and a yaw angle component Δφ. Since the functions thereafter are common to the other angle components, the roll angle component Δα will be described.

The roll angle component Δα is branched into two by a signal branching unit (not shown), one branching signal is a dead zone processing unit 233a, and the other branching signal is a high pass filter 235a.
Sent to

The processing outline of the dead zone processing section 233a is shown in FIG.
First, the low-frequency drift component is removed from the branch signal (S201). Then, if the amplitude change amount of the noise component is detected and it is within the region set as the dead zone in advance, the three-dimensional mouse 20 is not rotating,
That is, it is determined that the angular velocity is not generated (S20
2). Then, it is selected whether or not the offset cancellation processing is performed, that is, whether or not the amplitude value of the low frequency component is reset (S203). If the offset cancellation processing is not necessary (S203: No), the output is sent to the low pass filter 234a as it is. On the other hand, when the offset cancel process is necessary (S203: Yes), the offset process is executed (S204).

In the offset canceling process, as shown in FIG. 11, after extracting random noise (S301),
The high frequency component is removed and the offset value is extracted (S
302). A variable subtraction process is performed on this offset value (S303) to generate a correction signal for the gyro 22a (S304). By performing this offset cancellation processing, for example, the branch signal having the component shown in FIG. 12A is in a state where the offset value is canceled as shown in FIG. Are removed.

After passing through the dead zone processing section 233a, it is sent to the low-pass filter 234a, the high-frequency component thereof is removed, and then it is combined with the other branch signal from which the low-frequency component is removed via the high-pass filter 235a. By thus synthesizing the branch signals of different frequency components, the occurrence of an error due to a change in the frequency domain is suppressed as shown in FIG. 13, for example.

The combined signals are sequentially sent to the integrating circuit 236, where they are integrated and added at regular time intervals (20 ms in this example). Here, the trapezoidal method integration is adopted. this is,
This is a method of repeating the process of adding the integrated value at the time point one cycle before and the integrated value at the time point of the current cycle and dividing by 2. However, as described above, it is specified when the angular velocity signal is digitized. Since the averaging process is performed in time, the data accuracy of the integrated value obtained by this is quite high.

The angle data generator 237a includes an integrating circuit 2
The component integrated and added in 36a is converted into angle data, that is, the roll angle p. This roll angle p is bifurcated,
One is fed back to the coordinate conversion unit 232 as described above,
The other is sent to a data output unit (not shown).

The functional blocks and the processing contents thereof for the roll angle component Δα are the same for the pitch angle component Δβ and the yaw angle component Δφ, and the angle data generator 23
7b and 237c output angle data corresponding to the angular velocity signals of the respective axes, that is, pitch angle q and yaw angle r.

The main control unit 23 puts the angle data thus generated and the distance data based on the output data of the mouse unit 22 on a conventional mouse interface for transmitting two-dimensional data, and computer. To the data input section of. FIG. 14A shows a data transmission format by the above-mentioned conventional mouse interface, and shows that the X-axis movement amount and the Y-axis movement amount as distance data are alternately transmitted repeatedly. In this embodiment, as shown in FIG. 7B, following the X-axis movement amount and the Y-axis movement amount, the roll angle p, the pitch angle q, and the yaw angle r are represented by the X-axis rotation amount and the Y-axis rotation amount. Amount and Z-axis rotation amount are left as they are in the existing transmission area, and these are repeatedly transmitted as a set. On the computer side, pointer movement processing and rotation processing on the screen are performed based on these data.

The three-dimensional mouse 20 of the present embodiment configured as described above may be used on a desk or may be used while being separated from the desk. In the latter case, by changing the posture angle and yaw angle of the mouse body, the pointer on the computer screen can be displaced, and the pointer or the graphic data pointed to by the pointer can be rotated. It becomes possible to input data in the form.

Thus, the three-dimensional data input device of the present invention has been described in detail by showing two embodiments. However, the present invention is not limited to other data input devices having the same principle as a mouse, such as a ball. The above-mentioned effect can be obtained by applying it to a so-called trackball that is manually rotated to generate displacement data of a pointer or a pointing device that restricts movement of the pointer by pressurization.

[0049]

As is apparent from the above description, according to the three-dimensional data input device of the present invention, various kinds of information can be stored.
It becomes possible to input to the computer with a simple operation. Further, since the device configuration is simple, mass production is possible, and it is possible to satisfy both size reduction and cost reduction at the same time.
