Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a data input device for inputting coordinate data for moving or rotating an image on a screen on a computer.

[0002]

2. Description of the Related Art FIG. 6 is a plan view showing a conventional data input device using a so-called trackball.

[0003] A spherical operating body 1 called a trackball
Numeral 0 is rotatably supported in the three-dimensional direction, and the spherical encoder 10 drives the X encoder 12 and the Y encoder 13.

The X encoder 12 includes a roller 12a that rotates about an axis extending in the Y direction,
And a disk 12b that rotates together with the disk. Disk 12b
A notch is formed in the outer peripheral portion of the device, and the notched portion and a portion where the notch is not formed are alternately formed at a constant pitch in the circumferential direction. A photocoupler 12c faces the outer periphery of the disk 12b. In the photocoupler 12c, a light emitting element and a light receiving element are provided to face each other.
The outer periphery of the disk 12b is interposed between the light emitting element and the light receiving element. When the roller 12a and the disk 12b rotate, a pulse output having a frequency corresponding to the rotation speed of the disk 12b is obtained from the photocoupler 12c.

Similarly, the Y encoder 13 includes a roller 13a that rotates about an axis extending in the X direction, a disk 13b that rotates with the roller 13a, and a photocoupler 13c that faces the outer periphery of the disk 13b. Have been. On the outer periphery of the disc 13b, a notch and a portion where no notch is formed are formed repeatedly at a constant pitch in the circumferential direction, and the roller 13a and the disc 13b are formed from the photocoupler 13c. A pulse output having a frequency corresponding to the rotation speed of the motor is obtained.

A general input operation when the data input device is connected to a computer will be described.

When the spherical operation body 10 is rotated in the X direction, the roller 12a of the X encoder 12 and the disk 12 are rotated.
As b rotates, a pulse output is obtained from the photocoupler 12c, which is converted into coordinate data. When the coordinate data is input to the computer, for example, on a screen connected to the computer, a cursor or a character or object on the screen moves in the X direction. Also, if the operating tool 10 is Y
When rotated in the direction, the roller 1 of the Y encoder 13
3a and the disc 13b rotate, the pulse output from the photocoupler 13c is converted into coordinate data and input, and a cursor or the like moves in the Y direction on the screen.

When the operating body 10 is rotated, for example, in the direction α having angles on both the X axis and the Y axis, the roller 1
Both the roller 2a and the roller 13a are rotated, the pulses from both the photocoupler 12c and the photocoupler 13c are converted into coordinate data, and the cursor or the like moves on the screen in the α direction.

Further, for example, by rotating the operating tool 10 while pressing a predetermined key on the keyboard, it is possible to input rotation mode data as coordinate data. For example, when the operating body 10 is rotated in the X direction while pressing the key, and a pulse output is obtained from the photocoupler 12c of the X encoder 12, this is converted into rotation data on coordinates and input to the computer. As a result, for example, a character or an object projected on the screen rotates around the Y axis (the θy direction). Similarly, when the operating tool 10 is rotated in the Y direction while pressing the key, the character or the like is rotated around the X axis (θx direction) on the screen, for example.

That is, a character or the like on the screen rotates in the same direction as the spherical operation body 10. Therefore, when the operating tool 10 is rotated in the α direction, the character or the like rotates about an axis orthogonal to the α direction.

[0011]

As described above, the spherical operating body 10, the X encoder 12, and the Y encoder 1
3 can input coordinate data of a moving direction, a moving amount and a moving speed in two dimensions on XY coordinates, and in a rotation coordinate input mode, rotation data about the Y axis can be input. And rotation data about the X axis can be input. However, the input coordinate data is limited to the above, and has a drawback that, for example, the following input cannot be performed. (1) When inputting rotation data on coordinates, rotation data about a Z-axis orthogonal to the X-axis and the Y-axis cannot be input. That is, as described above, in the rotation mode in which a predetermined key is pressed, when the operating tool 10 is rotated in the X direction or in the Y direction, the character on the screen is moved in the same direction as the operating tool 10. It is possible to input data so as to rotate to. However, even if the operating tool 10 is rotated in the θz direction (direction around the Z axis) in FIG. 6, for example, rotation data about the Z axis cannot be input. In other words, even when the operating body 10 rotates in the θz direction, the X encoder 12 and the Y encoder 13 rotate according to the Y-axis component and the X-axis component of the operating body 10 at the time of this rotation. Thus, the character or the like only tries to rotate around the X axis and the Y axis. (2) The input device shown in FIG. 6 cannot input movement data in the Z-axis direction. Therefore, for example, it is impossible to input data for moving a character or an object appearing on the screen in the Z direction (the depth direction of the screen and the front direction). (3) In order to input rotation data about the Z axis or movement data in the Z axis direction, a Z encoder that rotates about the Z axis may be added. However, it is difficult to rotate the Z encoder with high precision using the operating body 10. That is, the roller 12a of the X encoder 12 and the roller 13a of the Y encoder 13 are located below the spherical operating body 10, and when the operating body 10 is rotated with a finger, the operating body 10 is moved in the Z-axis direction. Since the operation body 10 is pushed
Thus, the rollers 12a and 13a can be surely rotated. However, when the operating body 10 is rotated with a finger, it is difficult to reliably rotate the encoder having the axial direction in the Z-axis direction. (4) When rotating an object on the screen in a rotation mode in which a predetermined key is pressed, in the conventional input device shown in FIG. 6, the operating tool 10 must be kept rotating in order to continuously rotate. The operability was complicated. As a countermeasure, a switch for continuously operating the input device can be added, but this causes a problem that operability is further complicated. (5) As described above, in the conventional data input device, coordinate data other than data based on the X axis cannot be input using, for example, an X encoder, and similarly, the Y axis is input using a Y encoder. Coordinate data other than the reference data cannot be input. Therefore, as shown in FIG. 6, in the case of having only the X encoder 12 and the Y encoder 13, it is possible to input two-dimensional data on the basis of the XY coordinates, but to input three-dimensional data. Cannot be entered.

The present invention solves the above-mentioned conventional problems, and moves an image such as a character on a screen in a depth direction and a front direction with respect to the screen without using a device having a complicated structure and operability. It is an object of the present invention to provide a data input device capable of causing the data input device to rotate about the direction.

It is another object of the present invention to provide a data input device capable of easily controlling a rotation speed and a rotation direction of an image.

[0014]

According to the present invention, there is provided a data input device comprising: an operating body operated by hand; an angle detecting section operated by the operating body; and output data from the angle detecting section are displayed on a screen surface. And a switching unit for converting the data from the angle detection unit into Z-axis data perpendicular to the screen in the control unit. It is characterized by having.

In this case, the operating body can be held and rotated by hand, and the angle detecting section detects the inclination of the operating body itself, and the switching section controls the operating body by a predetermined angle in a predetermined direction. When it is tilted, the control unit can switch the conversion to the Z-axis data.

In the above means, when the operating body is rotated by a predetermined amount, for example, 90 degrees, the rotation data detected by the rotation is converted into data for moving an image. That is, the image on the screen can be moved around the screen from the back to the front. Thereby, when the image moves to the back side, it is displayed smaller than the initial state, and when the image moves to the near side of the screen, it is displayed larger than the initial state.

Further, the angle detecting section has an angle sensor for detecting the rotation of the operating body on each of the X, Y, and Z axes in the operating body. Preferably, data from the sensor is converted to Z-axis data.

As described above, X, Y, Z
By forming each of the three axes using an angle sensor, specifically, a vibration type gyro, the structure of the device itself can be formed simply and inexpensively. Note that the angle sensor in this case is not limited to one that detects angular velocity like a vibration type gyro and integrates this into angular data, but also one that can detect a gyro using light or other angles (tilts). It may be.

In this case, the angle sensor formed on the X-axis detects the rotation of the operating body on the X-axis.
Movement on the Y axis or rotation on the X axis can be controlled. Also Y
By detecting the rotation of the operating body on the Y axis, the angle sensor formed on the axis can control the rotation on the Y axis and the movement on the X axis. In addition, the rotation of the operating body on the Z axis can be controlled by the angle sensor formed on the Z axis.

In the data input device according to the present invention, the operation tool may include a start switch for starting output to an image, a changeover switch for switching between rotation and movement of the image, and a continuous operation switch for continuously operating the image. Can be provided.

By providing the three switches as described above, for example, when the operation is started, the start switch is pressed, and by pressing the changeover switch while the start switch is pressed, a mode in which the moving operation is performed is provided. Is converted.

In this case, when the image on the screen is moved in the same direction as the direction in which the operating tool is rotated on the X axis, that is, in the Y axis direction, and when the operating tool is rotated on the Y axis, Is the same direction as the rotated direction, that is, X
The image moves in the axial direction.

If the changeover switch is not depressed while the start switch is depressed, the mode is changed to a mode for performing a rotation operation.

In this case, when the operating tool is rotated on the X axis, the image can be rotated around the X axis.
When rotated on the axis, the image can be rotated about the Y axis.

Further, in the present invention, when the continuous mode is operated by the continuous operation switch, the rotation speed for rotating the image on the screen according to the rotation angle of the operating tool while the operation state is continued. Alternatively, the output can be output with the moving speed changed.

For example, when the operation body is rotated on the X axis by pressing the continuous operation switch while both the start switch and the changeover switch are pressed, the image is continuously displayed on the Y axis (vertical direction of the screen). When the image is moved and rotated on the Y axis, the image continuously moves on the X axis (in the horizontal direction of the screen).

When the operation body is rotated on the X axis by pressing the continuous operation switch while the start switch is pressed, the image on the screen rotates continuously around the X axis. When the operating tool is rotated on the Y axis while the start switch is pressed and the continuous operation switch is pressed, the image on the screen rotates continuously around the Y axis.

In the present invention, when the operating body is rotated to rotate or move an image at a rotation speed corresponding to the rotation angle, the operating body is further rotated to further rotate the operating body according to the rotation angle. Alternatively, the image can be output such that the moving speed is accumulated and the image is rotated or moved.

For example, it is assumed that the image is rotating at the rotation speed V1 when the operation body is operated in the rotation mode without pressing the changeover switch and the state where the operating body is inclined at the angle θ is maintained. By further tilting the angle to 2θ twice from this state, the rotation speed is accumulated and the image rotates at twice the rotation speed V1.

It is also assumed that the changeover switch is operated in the movement mode and the operating body is tilted at the angle θ to move the image at the moving speed of V2. By tilting the angle twice to 2θ from this state, the moving speed is accumulated, and the image moves at twice the moving speed V2.

Further, the speed of the image can be controlled by the amount and direction of the rotation angle of the operating body.

For example, when stopping the image from the rotating state, the operating body can be stopped by rotating the operating body in a direction opposite to the rotation direction at that time and giving a rotation speed in the opposite direction. By rotating the operation body, the operation body can be rotated in the opposite direction. Also, when moving the image, the operating tool can be stopped by rotating the operating tool in the opposite direction to the moving direction and giving a moving speed in the opposite direction. Can be moved in the opposite direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A data input device according to the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view showing a positional relationship when an operation is performed on a screen 2 on the computer side by using an operating tool 1 which is a main body of the data input device. In this case, the plane of the screen 2 is the X axis in the horizontal direction, the Y axis in the vertical direction, and the Z axis is the depth direction perpendicular to the screen 2.

As shown in FIG. 1, the operating body 1 is formed in a spherical shape or a shape that can be easily held by hand, and three switches A, B, and C are protruded outside the operating body 1. The switch A is a start switch for starting the operation of the image M displayed on the screen 2. The switch B is an image M
Is a changeover switch for switching between rotation and movement of the camera. When the switch is on, it is in the movement mode, and when it is off, it is in the rotation mode. The switch C is a continuous operation switch for continuously operating the image M, and these switches A, B, C
Are arranged in front of the operating body 1 in the vertical direction.

Further, a switch D is formed inside the operation body 1. The switch D is a tilt detection switch, and operates when the operating body 1 is tilted by 90 degrees (switch O).
N) and has a coordinate axis conversion function that enables the image M to move in the Z-axis direction.

The shape of the operating body 1 and the arrangement of the switches A, B, and C can be appropriately changed so as to be easily operated.

As shown in FIG. 3, sensors of vibration type gyros 4a, 4b, 4c are formed inside the operating body 1. The gyros 4a, 4b, 4c are formed on the X, Y, and Z axes, respectively.

The gyros 4a, 4b, and 4c can detect a rotational angular velocity on each axis, and can detect a rotational angle (inclination) by integrating the angular velocities. M can be rotated or moved. That is, by rotating the operating body 1 and rotating the gyro 4a on the X axis in the direction of the arrow (+ direction) in FIG. Upwards) or rotated about the X axis. Further, by rotating the operating body 1 and rotating the gyro 4b in the direction of the arrow (+ direction) on the Y axis, the image M can be moved leftward on the X axis on the screen or rotated about the Y axis. it can. Further, the image M is rotated counterclockwise on the Z axis (clockwise in the case of the negative direction) by rotating the gyro 4 c on the Z axis in the direction of the arrow (+ direction) by rotating the operating body 1. Can be. FIG. 4 shows an internal circuit diagram of the operating body 1.

As shown in FIG. 4, the gyros 4a, 4b,
4c is connected to an analog switch 5, and analog data having angular velocity data sent from the sensors of the gyros 4a, 4b, 4c is converted into digital data via an A / D converter 6, and sent to the control unit 3. It is processed. Further, when the operating body 1 is tilted to operate the switch D, the switching of the gyro to be used can be controlled by switching the analog switch 5 from the control unit 3 side.

The switches A provided on the operating body 1
The switch B, the switch C and the switch D are connected to the control unit 3, and information on ON / OFF operation of each of the switches A, B, C and D is sent to the control unit 3 and a predetermined process is performed.

In the operating tool 1 formed as described above, the control section 3 integrates the angular velocity data to obtain angle data, and controls the screen 2 on the host computer side.

By operating the switch A formed on the operating body 1, a signal to start sending data is transmitted to the control unit 3. At this time, the switch B is turned on and the operating body 1 is rotated to operate. In this case, the image can be moved in the Y-axis direction by rotating on the X-axis, and by rotating on the Y-axis. The image can be moved in the X-axis direction.

With the switch A pressed, the switch B
Is turned off, the image M can be converted from a moving operation to a rotating operation. In this case, the image M can be rotated about the X axis by rotating the operating tool 1 on the X axis, and the image M can be rotated about the Y axis by rotating on the Y axis. Further, by rotating on the Z axis, the image M can be rotated around the Z axis.

When the switch C is turned on while the switch A is pressed and the state is maintained, the continuous rotation mode is set, whereby the image M can be continuously rotated on the screen 2. In this case, the image M can be continuously rotated about the X axis by rotating the operating tool 1 on the X axis, and the image M can be rotated about the Y axis by rotating the operating tool 1 on the Y axis. The image M can be continuously rotated around the Z axis by rotating the operating body 1 on the Z axis.

When the switch A and the switch B are pressed and the continuous operation switch C is turned on and the state is maintained, the continuous movement mode is established, whereby the image M is continuously moved on the screen 2. be able to. In this case, the image M can be continuously moved in the Y-axis direction (the vertical direction of the screen) by rotating the operating tool 1 on the X-axis, and the image can be moved by rotating the operating tool 1 on the Y-axis. M can be continuously moved in the X-axis direction (screen horizontal direction). Further, when rotated on the Z axis, the image M can be rotated around the Z axis.

Further, when the operating tool 1 is tilted by 90 degrees (the operating tool 1 shown in FIG. 1 is turned backward by 90 degrees), the switch D is turned ON, and an input for moving the image M in the Z-axis direction becomes possible. The operating method at this time is as follows. The operating body 1 shown in FIG. 1 is gripped by hand, and the arm is rotated by 90 degrees or more (front side) with the elbow as a fulcrum. Can be performed by rotating.

That is, when the switch D is turned on, the control unit 3 detects the state of the switch D, and sends a signal from the control unit 3 so that only the gyro 4a among the gyros 4a, 4b, and 4c functions. Can be

In this case, the image M moves in the depth direction (front-back direction) with respect to the screen 2 by maintaining the state where the operating body 1 is tilted by 90 degrees and performing a rotation operation on the X axis. Become.

The image M can be continuously moved in the depth direction (front-back direction) with respect to the screen 2 by holding the above-mentioned state, that is, the state where the operating body 1 is tilted, and turning on the switch C. .

In the apparatus according to the present invention, the image M is determined by the amount and direction of the angle at which the operating body 1 is rotated (tilted).
Can control the moving speed and the rotating speed.

That is, since the gyros 4a, 4b and 4c actually detect the angular velocity, the control section 3 integrates the angular velocity with respect to time to calculate the angle data. Using the angle data, the image M is output in accordance with the moving speed and the rotating speed of the image M.

For example, when the operating body 1 is rotated at the rotation angle θ on the Y axis while the switches A and C are operating, and the rotating speed at that time is operating at V1,
By rotating the operating tool 1 in the reverse direction by the angle θ from the above state, the rotation speed (−V1) generated by the rotation is added, the speed becomes zero, and the image M stops on the screen 2. Further, the image M operates at twice the speed of V1 by further rotating the angle θ in the same direction from the state of the rotation angle θ described above and rotating the image M at the rotation angle 2θ.

As described above, the rotation speed and the movement speed of the image M displayed on the screen 2 can be controlled by the amount of the rotation angle of the operating tool 1 and the direction of the rotation angle. Note that the angular velocity data obtained by the gyro may be directly used as the moving speed of the image M.

FIG. 5 shows a flow chart of the circuit used in the above-mentioned data input device.

When operating the operating body 1, first, in step 1 (ST1), the control section 3 monitors whether or not the switch A which is the operation start switch has been operated, and detects the operation of the switch A. Waiting for you.
After the operation (switch-on state) of the switch A is confirmed, the gyro 4a, 4
b, 4c, sensor read data (angular velocity data) GyroX, GyroY, and GyroZ are arithmetic buffers DATAX, DAT dedicated to the X, Y, and Z axes, respectively.
AY and DATAZ are stored (ST2 to ST4). For example, at this time, when the rotation is performed about another axis formed by the X axis and the Y axis, the sensor read data GyroX and GyroY by the gyros 4a and 4b are stored in the respective calculation buffers.

Next, it is monitored whether or not the switch C for continuous operation has been operated (ST5). At this time, the switch C is turned on.
In step ST6, zero is stored in the continuous mode operation buffer for continuous operation in ST6. That is, since zero is stored in the continuous mode calculation buffer, only the sensor read data read from the gyros 4a, 4b, 4c by operating the operating tool 1 is stored in the calculation buffer,
It is possible to continuously move at a speed calculated based on the read data.

If the switch C is OFF in ST5, the operation of the switch B for switching between movement and rotation and the switch D for detecting inclination are monitored (ST7).
When both switches B and D are ON, S
The process proceeds to T6, and similarly, zero is stored in the continuous mode operation buffer.

If it is not detected in the step ST7 that the switches B and D are ON, that is, if only the switch A is ON, a simple movement mode is set. At this time, the operating body 1 is operated and the gyro 4
The sensor read data sent from a, 4b, and 4c is stored in the calculation buffer. By further operating the operating body 1 to rotate the gyros 4a, 4b, and 4c, the gyro 4a, 4b, and 4c are rotated according to the amount and direction of the rotation angle. The sensor read data relating to the angle is added to the calculation buffer (ST
8, ST9).

Further, the operation of the switch B is confirmed in ST10. When the operation of the switch B is detected to be ON, the sensor read data by the gyro 4b formed on the Y axis is transferred to the X axis movement output buffer (D
outX) (ST11).

Next, the operation state of the switch D is monitored, and when the switch D is OFF, the sensor read data around the X axis by the gyro 4a is reversed in sign (see the rotation sign in FIG. 3) in the Y axis direction. Is stored in the movement output buffer for controlling (ST13), and zero is stored in the movement output buffer in the Z-axis direction at that time. As a result, the data stored in the movement output buffer is processed by the control unit 3, and the image M is controlled to move in the Y-axis direction.

When the switch D is operated in ST12, the sensor read data around the X-axis by the gyro 4a is stored in a movement output buffer for controlling the Z-axis direction (ST18), and the Y-axis direction is stored. Zero is stored in the movement output buffer to be controlled. The data stored in the movement output buffer in this way is processed by the control unit 3, and the image M can be moved in the Z-axis direction, that is, in the depth direction of the screen.

In ST10, switch B is turned off.
In the case of F, when sensor reading data on the X-axis is detected by the gyro 4a, the data is stored in a rotation output buffer for rotation, that is, pitch (PITCH) (ST15). When the gyro 4b detects sensor read data on the Y-axis, the data is stored in a rotation output buffer for rotation, that is, yaw (YAW) (ST16). When the gyro 4c detects sensor read data on the Z axis, the data is stored in a rotation output buffer for rotation, that is, roll (ROLL) (ST17).

By storing data in the rotation output buffer as described above, the image M rotates in the state shown in FIG. That is, in the case of PITCH, a rotational movement occurs on a plane formed by the Y axis and the Z axis,
In the case of AW, rotational movement occurs on a plane formed by the X axis and the Z axis, and in the case of ROLL, rotational movement occurs on a plane formed by the X axis and the Y axis.

As described above, the image M on the screen 2 is
Movement in the axial and Y-axis directions, rotation on the X-axis, rotation on the Y-axis, and rotation on the Z-axis, as well as movement in the Z-axis direction can be controlled.

When it is desired to return the image M to the initial state, for example, to the center of the screen 2, it is possible to perform setting by pressing an arbitrarily set key of a keyboard connected to the host computer. .

The data exchange between the operating tool 1 and the host computer may be of a wired type using a cable, or of a wireless type in which a device capable of transmitting / receiving data to / from the operating tool 1 and the host computer is formed. May be.
