[0001]
BACKGROUND OF THE INVENTION
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]
[Prior art]
FIG. 6 is a plan view showing a conventional data input device using a so-called trackball.
[0003]
A spherical operation body 10 called a trackball is supported to be rotatable in a three-dimensional direction, and the X encoder 12 and the Y encoder 13 are driven by the spherical operation body 10.
[0004]
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 roller 12a. Notches are formed in the outer peripheral portion of the disc 12b, and the notches and portions where no notches are formed are alternately formed at a constant pitch in the circumferential direction. A photocoupler 12c is opposed to the outer periphery of the disc 12b. The photocoupler 12c is provided with a light emitting element and a light receiving element facing each other, and an outer peripheral portion of a disc 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 rotational speed of the disk 12b is obtained from the photocoupler 12c.
[0005]
Similarly, the Y encoder 13 includes a roller 13a that rotates about an axis extending in the X direction, a disk 13b that rotates together with the roller 13a, and a photocoupler 13c that faces the outer periphery of the disk 13b. . On the outer peripheral portion of the disc 13b, a notch and a portion where no notch is formed are repeatedly formed at a constant pitch in the circumferential direction. From the photocoupler 13c, a roller 13a and a disc 13b are formed. A pulse output having a frequency corresponding to the rotation speed of the motor is obtained.
[0006]
A general input operation when the data input device is connected to a computer will be described.
[0007]
When the spherical operating body 10 is rotated in the X direction, the roller 12a and the disc 12b of the X encoder 12 rotate, and a pulse output is obtained from the photocoupler 12c, which is converted into coordinate data. When this 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. When the operation body 10 is rotated in the Y direction, the roller 13a and the disk 13b of the Y encoder 13 rotate, and the pulse output from the photocoupler 13c is converted into coordinate data and input. Move in the Y direction.
[0008]
Further, when the operating body 10 is rotated, for example, in the α direction having an angle with respect to both the X axis and the Y axis, both the roller 12a and the roller 13a are rotated, and the pulses from both the photocoupler 12c and the photocoupler 13c It is converted to data and the cursor moves in the α direction on the screen.
[0009]
For example, rotation mode data can be input as coordinate data by rotating the operating tool 10 while pressing a predetermined key on the keyboard. 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 object projected on the screen rotates around the Y axis (θy direction). Similarly, when the operating body 10 is rotated in the Y direction while pressing the key, the character or the like rotates around the X axis (θx direction), for example, on the screen.
[0010]
That is, the character on the screen rotates in the same direction as the spherical operation body 10. Therefore, when the operating body 10 is rotated in the α direction, the character or the like rotates around an axis orthogonal to the α direction.
[0011]
[Problems to be solved by the invention]
As described above, in the data input device including the spherical operation body 10 and the X encoder 12 and the Y encoder 13, the coordinate data of the moving direction, moving amount, and moving speed in two dimensions on the XY coordinates. In the rotation coordinate input mode, it is possible to input rotation data about the Y axis and rotation data about the X axis. However, the input coordinate data is limited to the above-mentioned one, and has a drawback that the following input cannot be performed, for example.
(1) When inputting rotation data on coordinates, rotation data about the Z axis orthogonal to the X axis and the Y axis cannot be input. That is, as described above, when the operating body 10 is rotated in the X direction or rotated in the Y direction in the rotation mode in which a predetermined key is pressed, the character on the screen is rotated in the same direction as the operating body 10. It is possible to input data so as to rotate it. However, for example, even if the operating body 10 is rotated in the θz direction (direction around the Z axis) in FIG. 6, rotation data about the Z axis cannot be input. That is, even if the operating body 10 rotates in the θz direction, the X encoder 12 and the Y encoder 13 rotate due to the Y-axis component and the X-axis component of the operating body 10 during this rotation, and according to the output pulse. Thus, the character only tries to rotate around the X axis and the Y axis.
(2) In addition, 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 object appearing on the screen in the Z direction (the back direction and the near side of the screen).
(3) In order to input rotation data around the Z axis or movement data in the Z axis direction, a Z encoder that rotates around the Z axis may be added. However, it is difficult to rotate the Z encoder with the operating body 10 with high accuracy. That is, the roller 12a of the X encoder 12 and the roller 13a of the Y encoder 13 are positioned below the spherical operation body 10, and when the operation body 10 is rotated by a finger, the operation body 10 moves in the Z-axis direction. Therefore, the rollers 12a and 13a can be reliably rotated by the operating body 10. 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) Also, when rotating an object or the like 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 body 10 must be continuously rotated in order to perform the rotation continuously. The operability was complicated. As a countermeasure, a switch for continuously operating the input device can be added, but this causes a problem that the operability is further complicated.
(5) As described above, in the conventional data input device, for example, coordinate data other than data based on the X axis cannot be input using the X encoder, and the Y axis is similarly used using the 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 based on the XY coordinates, but three-dimensional data. Can not enter.
[0012]
The present invention solves the above-mentioned conventional problems, and without using a device having a complicated structure and operability, moves an image such as a character on the screen in the back direction and the near side with respect to the screen, and An object of the present invention is to provide a data input device that can be rotated around a direction.
[0013]
It is another object of the present invention to provide a data input device that can easily control the rotation speed and rotation direction of an image.
[0014]
[Means for Solving the Problems]
  A data input device according to the present invention includes an operating body operated by a hand, an angle detection unit operated by the operating body, and movement of output data from the angle detection unit on an XY coordinate on the surface of the screen. A control unit for converting data into rotation data, and a switching unit for converting data from the angle detection unit into Z-axis data perpendicular to the screen in the control unit;Have
  The operating body includes start means for starting output to an image, switching means for switching between rotation and movement of the image, and continuous operation means for continuously operating the image.Is provided.
[0015]
  In this case, the operating body can be held and rotated by the hand, the angle detection unit detects the inclination of the operating body itself, and the switching unit is tilted in a predetermined direction at a predetermined angle. In this case, the control unit can switch the conversion to Z-axis data.By providing the three switches as described above, for example, when the operation is started, the start switch is pressed, and the mode is changed to a mode in which the moving operation is performed by pressing the changeover switch while the start switch is pressed. Is done.
[0016]
In the above means, the rotation data detected by the rotation when the operating body is rotated by a predetermined amount, for example, 90 degrees, is converted into data for moving the image. That is, the image on the screen can move from the back direction of the screen with the near side as the axis. As a result, when the image moves to the back side, the image is reduced and displayed from the initial state, and when the image moves to the near side of the screen, the image is enlarged and displayed from the initial state.
[0017]
Further, the angle detection unit is arranged with an angle sensor for detecting rotation of the operating body on the X, Y, and Z axes in the operating body, respectively, and when switched by the switching unit, from any of the angle sensors. The data is preferably converted to Z-axis data.
[0018]
As described above, the structure of the device itself can be easily and inexpensively formed by using an angle sensor, specifically a vibrating gyroscope, on the X, Y, and Z axes in the operating body. it can. Note that the angle sensor in this case is not limited to detecting angular velocities and integrating them into angle data, such as a vibrating gyroscope, and can detect gyroscopes using light or other angles (tilts). It may be.
[0019]
In this case, the angle sensor formed on the X-axis can control the movement on the Y-axis or the rotation on the X-axis by detecting the rotation on the X-axis of the operating body. Further, the angle sensor formed on the Y axis can control the rotation on the Y axis and the movement on the X axis by detecting the rotation of the operating body on the Y axis. Further, the angle sensor formed on the Z axis can control the rotation of the operating body on the Z axis.
[0022]
In this case, the image on the screen moves in the same direction as the direction rotated by rotating the operating body on the X axis, that is, the Y-axis direction, and when the operating body is rotated on the Y axis, the rotation is performed. The image moves in the same direction as that of the direction, that is, the X-axis direction.
[0023]
Further, when the start switch is pressed and the changeover switch is not pressed, the mode is converted to a mode in which the rotation operation is performed.
[0024]
In this case, when the operating body is rotated on the X axis, the image can be rotated around the X axis, and when the operating body is rotated on the Y axis, the image can be rotated around the Y axis.
[0025]
  In the present invention, the continuous operationmeansWhen the continuous mode is activated, the rotation speed of rotating the image on the screen or the moving speed of moving is changed and output according to the rotation angle of the operating body while this operation state continues. Can do.
[0026]
For example, when both the start switch and the changeover switch are pressed and the continuous operation switch is pressed and the operating body is rotated on the X axis, the image continuously moves on the Y axis (the vertical direction of the screen) When rotated on the Y axis, the image continuously moves on the X axis (horizontal direction of the screen).
[0027]
When the operation switch is rotated on the X axis by pressing the continuous operation switch while the start switch is pressed, the image on the screen is continuously rotated around the X axis. When the operating body is rotated on the Y axis while the start switch is pressed and the continuous operation switch is pressed, the image on the screen is continuously rotated around the Y axis.
[0028]
In the present invention, when the operation body is rotated and the image is rotated or moved at a rotation speed corresponding to the rotation angle, the operation body is further rotated to rotate the operation body according to the rotation angle or the movement speed. Can be output by rotating or moving the image.
[0029]
For example, it is assumed that the image is rotated at the rotation speed V1 when the operation body is operated in the rotation mode without pressing the changeover switch and the operation body is held at an angle θ. By further tilting the angle to 2θ from this state, the rotational speed is accumulated, and the image is rotated at twice the rotational speed V1.
[0030]
In addition, it is assumed that the changeover switch is operated in the movement mode and the operation body is tilted by an angle θ to move the moving speed of the image by V2. By further tilting the angle to 2θ from this state, the moving speed is accumulated, and the image moves at twice the moving speed V2.
[0031]
Further, the image speed can be controlled by the amount and direction of the rotation angle of the operating body.
[0032]
For example, when the image is stopped from the rotation state, the operation body can be stopped by rotating the operation body in the opposite direction to the rotation direction at that time to give a reverse rotation speed. By rotating it, it can be rotated in the opposite direction. Also, when moving an image, the operating body can be stopped by rotating the operating body in the opposite direction to the moving direction and giving a moving speed in the opposite direction. It can be moved in the reverse direction.
[0033]
DETAILED DESCRIPTION OF THE INVENTION
The data input device of the present invention will be described below with reference to FIGS.
[0034]
FIG. 1 is a perspective view showing an arrangement relationship when an operation on a screen 2 on a computer side is performed using an operating tool 1 which is a data input device main body. 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 depth direction perpendicular to the screen 2 is the Z axis.
[0035]
As shown in FIG. 1, the operation 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 project from the operation 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 a change-over switch for switching between rotation and movement of the image M. When the switch B is on, the switch B is in the movement mode, and when it is off, the switch B is in the rotation mode. The switch C is a continuous operation switch for continuously operating the image M, and these switches A, B, and C are arranged in front of the operation body 1 in the vertical direction.
[0036]
Further, a switch D is formed inside the operation body 1. This switch D is an inclination detection switch, and operates (switch ON) when the operating body 1 is inclined by 90 degrees, and has a coordinate axis conversion function that enables the image M to move in the Z-axis direction.
[0037]
In addition, 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 easy to operate.
[0038]
Further, as shown in FIG. 3, sensors using vibration-type gyros 4 a, 4 b, and 4 c are formed inside the operation body 1. The gyros 4a, 4b and 4c are formed on the X axis, the Y axis and the Z axis, respectively.
[0039]
The gyros 4a, 4b, and 4c can detect rotational angular velocities on the respective axes, and can detect a rotational angle (tilt) by integrating the angular velocities, and rotate the image M at a speed corresponding to the rotational angle. Or can be 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. It can be moved upward) or rotated about the X axis. Further, by rotating the operating body 1 and rotating the gyro 4b in the arrow direction (+ direction) on the Y axis, the image M can be moved leftward on the X axis on the screen or rotated around the Y axis. it can. Further, by rotating the operating body 1 and rotating the gyro 4c on the Z axis in the arrow direction (+ direction), the image M is rotated counterclockwise (clockwise in the case of the-direction) on the Z axis. Can do.
FIG. 4 shows an internal circuit diagram of the operating tool 1.
[0040]
As shown in FIG. 4, the gyros 4 a, 4 b, 4 c are connected to the analog switch 5, and analog data having angular velocity data sent from the sensors of the gyros 4 a, 4 b, 4 c is digitally transmitted via the A / D converter 6. It is converted into data and sent to the control unit 3 for processing. In addition, when the operating body 1 is tilted to operate the switch D, switching of the gyro to be used can be controlled by switching the analog switch 5 from the control unit 3 side.
[0041]
The switches A, B, C, and D provided on the operating body 1 are connected to the control unit 3, and information on the ON / OFF operation of each switch A, B, C, D is sent to the control unit 3. And a predetermined process is performed.
[0042]
In the operating body 1 formed as described above, the control unit 3 integrates the angular velocity data to obtain angle data, and the screen 2 on the host computer side is controlled.
[0043]
In addition, by operating the switch A formed on the operation body 1, a signal to start sending data is transmitted to the control unit 3. At this time, the operation body 1 is operated by turning the switch B to ON. In this case, by rotating on the X axis, the image can be moved in the Y axis direction, and by rotating on the Y axis. The image can be moved in the X-axis direction.
[0044]
By turning off the switch B while the switch A is pressed, 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 body 1 on the X axis, and the image M can be rotated about the Y axis by rotating on the Y axis. Further, the image M can be rotated around the Z axis by rotating on the Z axis.
[0045]
In addition, when the switch A is pressed and the switch C is turned ON and this state is maintained, the continuous rotation mode is entered, whereby the image M can be continuously rotated on the screen 2. In this case, the image M can be rotated continuously around the X axis by rotating the operating tool 1 on the X axis, and the image M can be rotated around 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.
[0046]
In addition, 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 set, and the image M can be continuously moved on the screen 2. . In this case, the image M can be moved continuously in the Y-axis direction (vertical direction of the screen) by rotating the operating tool 1 on the X axis, and the image can be obtained by rotating the operating tool 1 on the Y axis. M can be moved continuously in the X-axis direction (screen horizontal direction).
Further, if the image M is rotated on the Z axis, the image M can be rotated around the Z axis.
[0047]
Further, by tilting the operating tool 1 by 90 degrees (the operating tool 1 shown in FIG. 1 is moved 90 degrees backward), the switch D is turned on, and an input for moving the image M in the Z-axis direction is possible. As an operation method at this time, the operation body 1 shown in FIG. 1 is grasped with a hand and the arm is tilted so that the arm is rotated backward 90 degrees or more (front side) with the elbow as a fulcrum. This can be done by rotating.
[0048]
That is, when the switch D is turned on, the control unit 3 detects the state of the switch D, and a signal is sent from the control unit 3 so that only the gyro 4a of the gyro 4a, 4b, 4c functions.
[0049]
In this case, the image M moves in the depth direction (front-rear direction) with respect to the screen 2 by maintaining the state in which the operating body 1 is inclined by 90 degrees and performing the rotation operation on the X axis.
[0050]
Further, the image M can be continuously moved in the depth direction (front-rear direction) with respect to the screen 2 by holding the state, that is, the state in which the operation body 1 is inclined and turning on the switch C.
[0051]
In the apparatus of the present invention, the moving speed and rotating speed of the image M can be controlled by the amount and the direction of the angle at which the operating body 1 is rotated (tilted).
[0052]
That is, since the angular velocities are actually detected in the gyros 4a, 4b, and 4c, the angular data is calculated by integrating the angular velocities with time in the control unit 3. Using this angle data, the image M is output in correspondence with the moving speed and rotational speed.
[0053]
For example, in the state where the switch A and the switch C are operating, when the operating body 1 is rotated at the rotation angle θ on the Y axis and the rotational speed at that time is operating at V1, the operating body 1 is moved from the above state. By rotating the angle θ in the reverse direction, 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 a speed twice that of V1 by further rotating the angle θ in the same direction from the state of the rotation angle θ and rotating the rotation angle 2θ.
[0054]
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 body 1 and the direction of the rotation angle. The angular velocity data obtained by the gyro may be used as the moving velocity of the image M as it is.
[0055]
FIG. 5 shows a flowchart of a circuit used in the data input device described above.
[0056]
When operating the operating body 1, first, in step 1 (ST1), whether or not the switch A which is the operation start switch has been operated is monitored by the control unit 3, and waits until the operation of the switch A is detected. is doing. By operating the operating body 1 after confirming the operation of the switch A (switch-on state), sensor read data (angular velocity data) GyroX, GyroY, and GyroZ read from the gyros 4a, 4b, and 4c are respectively X, It is stored in the operation buffers DATAX, DATAY, and DATAZ dedicated to the Y and Z axes (ST2 to ST4). For example, when rotating around another axis formed by the X axis and the Y axis at this time, sensor read data GyroX and GyroY by the gyros 4a and 4b are stored in the respective calculation buffers.
[0057]
Next, it is monitored whether or not the switch C for continuous operation is operated (ST5). If the switch C is ON at this time, zero is stored in the continuous mode calculation buffer for continuous operation in ST6. . That is, when zero is stored in the continuous mode calculation buffer, only the sensor read data read from the gyros 4a, 4b, and 4c is stored in the calculation buffer by operating the operating body 1, and the read data is stored in the calculation buffer. It can be continuously moved at the speed calculated based on the original.
[0058]
When the switch C is OFF in ST5, the operation of the switch B for switching between movement and rotation and the operation of the switch D for tilt detection are monitored (ST7), and when both switches B and D are ON. In the same manner as described above, the process proceeds to ST6, and similarly, zero is stored in the continuous mode calculation buffer.
[0059]
Further, when it is not detected in ST7 that the switch B and the switch D are ON, that is, when only the switch A is ON, the mode is a simple movement mode. At this time, the sensor reading data sent from the gyros 4a, 4b, 4c is stored in the calculation buffer by operating the operating tool 1, but by further operating the operating tool 1 to rotate the gyros 4a, 4b, 4c. Then, sensor read data relating to the amount and direction of the rotation angle is added to the calculation buffer (ST8, ST9).
[0060]
In ST10, the operation of the switch B is confirmed. When it is detected that the operation of the switch B is ON, the sensor read data by the gyro 4b formed on the Y axis is stored in the X axis movement output buffer (DoutX) (ST11).
[0061]
Next, the operating state of the switch D is monitored. If the switch D is OFF, the sensor read data around the X axis by the gyro 4a is reversed (see the rotation code in FIG. 3) to control the Y axis direction. It is stored in the movement output buffer (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 as movement in the Y-axis direction.
[0062]
When the switch D is operating in ST12, the sensor reading data around the X axis by the gyro 4a is stored in the movement output buffer for controlling the Z axis direction (ST18), and the movement for controlling the Y axis direction is stored. Zero is stored in the output buffer. In this way, the data stored in the movement output buffer is processed by the control unit 3, and the image M can be moved in the Z-axis direction, that is, the depth direction of the screen.
[0063]
In ST10, when the switch B is OFF, when the sensor read 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 sensor reading data on the Y axis is detected by the gyro 4b, the data is stored in a rotation output buffer for rotation, that is, yaw (ST) (ST16). When the sensor read data on the Z axis is detected by the gyro 4c, the data is stored in a rotation output buffer for rotation, that is, roll (ST17).
[0064]
By storing the data in the rotation output buffer as described above, the image M rotates in a state as shown in FIG. That is, in the case of PITCH, rotational movement occurs on the surface formed by the Y axis and the Z axis, and in the case of YAW, rotational movement occurs on the surface formed by the X axis and the Z axis. In some cases, rotational movement occurs on the surface formed by the X and Y axes.
[0065]
As described above, the movement of the image M on the screen 2 in the X-axis direction and the Y-axis direction, the rotation on the X-axis, the rotation on the Y-axis, and the rotation on the Z-axis is further controlled. It becomes possible.
[0066]
When the image M is desired to be returned to the initial state, for example, the center of the screen 2, it can be set so as to be performed by pressing an arbitrarily set key on a keyboard connected to the host computer.
[0067]
Further, the data exchange between the operating tool 1 and the host computer may be a wired type using a cable, or a wireless type in which devices capable of transmitting and receiving between the operating tool 1 and the host computer are formed.
[0068]
【The invention's effect】
As described above, the data input device of the present invention can move the image on the screen in the depth direction of the screen with a simple device and operation, and the magnitude of the rotation speed can be determined by the amount of the angle by which the operation tool is rotated. Further, the rotation speed can be controlled by the direction of the rotation angle.
