  The connection unit 5 is a connection terminal for connecting to the personal computer 30 when placed on the cradle 20, and also functions as a power input terminal for charging a battery (not shown) of the operation device 1.

  The inclination angle detection unit 6 is an inclination sensor using an acceleration sensor such as a capacitance type, a piezoresistive type, or a heat distribution detection type. For example, referring to FIG. 1, the main surface portion, that is, the display surface of the display portion 3. Attitude signals corresponding to the inclinations of the X axis and the Y axis that are parallel to each other and orthogonal to each other, and the Z axis that is perpendicular to the main surface portion are output to the AD converter 7. In the present embodiment, the X axis is set in the vertical direction of the display unit 3, and the Y axis is set in the horizontal direction of the display unit 3.

  As the tilt angle detector 6, a fixed beam and a movable beam (beam) are regarded as electrode plates of capacitors, respectively, and variation in the distance between the beams is set as an electrostatic capacitance value in the X axis, Y axis, When a capacitance type triaxial acceleration sensor that detects the inclination of the Z axis (the axis perpendicular to the main surface as shown in FIG. 1 is used as the Z axis) is used, as shown in FIG. , An output voltage corresponding to the tilt angle of the Y axis and the Z axis is obtained as an attitude signal.

  The AD conversion unit 7 converts the attitude signal output from the tilt angle detection unit 6 into a digital signal and outputs the digital signal to the motion detection unit 9, the reference angle setting unit 41, and the coordinate conversion unit 8.

When the operation key 4 is pressed for a predetermined time or longer in the power-on state, that is, when the setting of the first reference angle A is instructed, the reference angle setting unit 41 is configured to select the X axis and the X axis based on the attitude signal input from the AD conversion unit 7. The respective rotation angles θ _x and θ _y of the controller device 1 each centered on the Y axis are calculated, and the calculated rotation angles θ _x and θ _y are used as the first reference angle A (rotation angles θ _x1 , θ _y1 ). It is stored in the reference angle storage unit 42. The rotation angle θ _x can be obtained from the inclination angles of the Y axis and the Z axis, and the rotation angle θ _y can be obtained from the inclination angles of the X axis and the Z axis. Hereinafter, the rotation of the controller device 1 around the X axis is referred to as rotation in the pitch direction, and the rotation of the controller device 1 around the Y axis is referred to as rotation in the roll direction. Further, the rotation angles θ _x and θ _y in the case where the main surface portion of the housing 2 is orthogonal to the direction of gravity are set to 0 degrees, and the rotation in the pitch direction for moving the display unit 3 upward is added to the plus. Rotation in the pitch direction for moving the lower part of the display unit to the lower side is negative, rotation in the roll direction for moving the right side of the display unit 3 to the lower side is positive, and rotation in the roll direction to move the left side of the display unit to the lower side Rotation is negative. In the present embodiment, the operation key 4 is pressed for a predetermined time or more in the power-on state to instruct the setting of the first reference angle A. However, the instruction to set the first reference angle A is given. A key to be performed may be newly provided, and an instruction to set the first reference angle A may be given from an operation screen displayed on the display unit 3.

The reference angle storage unit 42 includes a first reference angle A (rotation angles θ _x1 , θ _y1 ) set by the reference angle setting unit 41 as a reference for the tilt of the operation device 1 when the operation device 1 is held by a hand. Is stored, and second reference angles (rotation angles θ _x2 , θ _y2 ) that serve as a reference for the tilt in the operating device 1 when used by being placed on the cradle 20 shown in FIG. 3 are stored. In the present embodiment, as shown in FIG. 2, when used by grasping with a hand, the display surface of the display unit 3 is initially set to be horizontal, and the first reference angle A is The rotation angles θ _x1 = 0 ° and θ _y1 = 0 ° are initially set, and when the operating device 1 is placed on the cradle 20 and used as shown in FIG. Therefore, the second reference angle B is set to θ _x2 = −90 ° and θ _y2 = 0 °. The reference angle storage unit 42 stores in advance a design posture signal (hereinafter referred to as a reference posture signal) output from the tilt angle detection unit 6 in a state where the controller device 1 is placed on the cradle 20. In addition to being stored, the drift correction value calculated by the drift correction operation by the coordinate conversion unit 8 is stored.

The coordinate conversion unit 8 calculates the respective rotation angles θ _x and θ _y of the controller device 1 centered on the X axis and the Y axis based on the attitude signal input from the AD conversion unit 7, and the reference angle By referring to the first reference angle A (rotation angles θ _x1 , θ _y1 ) stored in the storage unit 42, a posture vector R indicating the inclination of the controller device 1 from the first reference angle A is calculated and the cursor is calculated. Output to the control unit 15. The posture vector R is calculated as a vector from the first reference angle A (rotation angles θ _x1 , θ _y1 ) to the calculated (rotation angles θ _x , θ _y ), as shown in FIG. It is represented by an angle θ _a indicating in which direction the first reference angle A is tilted and a length r indicating the magnitude of the tilt angle from the first reference angle A of the controller device 1. Note that the calculation of the orientation vector R in the coordinate conversion unit 8 is performed every sampling time in the AD conversion unit 7.

Further, the coordinate conversion unit 8 is configured so that the X-axis and the Y-axis are centered on the X-axis and the Y-axis based on the attitude signal input from the AD conversion unit 7 in a state where the operation device 1 is placed on the cradle 20. Each rotation angle θ _x , θ _y is calculated, and the second reference angle (rotation angle θ _x2 , θ _y2 ) stored in the reference angle storage unit 42 is referred to, so that the second of the controller device 1 is obtained. A posture vector R indicating an inclination from the reference angle B is calculated and output to the cursor control unit 15.

Further, when the drift correction value is stored in the reference angle storage unit 42, the coordinate conversion unit 8 outputs the attitude signal output from the tilt angle detection unit 6 and input from the AD conversion unit 7 to the drift correction value. The X-axis and Y-axis rotation angles θ _x and θ _y and the attitude vector R are calculated based on the corrected attitude signal.

  The motion detection unit 9 detects “slap” and “shake” motions performed on the controller device 1 and outputs a motion detection signal indicating the detected motion to the cursor control unit 15.

  FIG. 7A shows an example of a posture signal output from the tilt angle detection unit 6 when the “tap” operation is performed on the main surface portion of the controller device 1. It can be seen that the change per hour is large. Therefore, the motion detection unit 9 calculates the Z-axis output at each sampling time in the AD conversion unit 7 as one sample, and calculates (difference from the sample after one sample * 100) as the displacement. When the displacement amount calculated by the motion detection unit 9 is plotted in time series as “0” when the displacement amount is less than 5, the result is as shown in FIG. 7B, and the motion detection unit 9 determines the displacement amount in advance. It is detected that the “tapping” operation has been performed based on a value having an instantaneous large slope indicated by A in FIG. 7B exceeding the threshold value ± α. Note that the displacement amount becomes a large value several times until it is attenuated after detection of the “tap” motion. Therefore, the motion detection unit 9 is a time set in advance as the decay time after detection of the “tap” motion. During Ta, control is performed so that the “tapping” operation is not detected. In the present embodiment, the “tap” operation is detected based on the output of the Z axis. However, depending on the location where the operation device 1 is “tapped”, the output of the X axis and the Y axis is remarkable. There may be a change, and the “tapping” operation may be detected based on the outputs of the X axis and the Y axis. Further, it is possible to detect the number of “tapping” operations from the number of detections. That is, the posture signal in the “tapping” motion is generated only when an impact is applied to the housing, so that it is difficult to distinguish it from an unintended impact. A method of determining “tap” only when a posture signal is detected can be considered.

  FIG. 8A shows an example of an attitude signal output from the tilt angle detection unit 6 when a “shaking” operation is performed on the controller device 1, and includes an X axis, a Y axis, and a Z axis. It can be seen that all of the axes change up and down at predetermined intervals. Therefore, the motion detection unit 9 calculates the X-axis output for each sampling time in the AD conversion unit 7 as one sample, and calculates (difference from the sample after 4 samples * 100) as the displacement amount. When the displacement amount calculated by the motion detection unit 9 is “0” when the displacement amount is less than 5 and when a value other than “0” is not consecutive for 5 samples or more, it is plotted as “0” in time series, As shown in FIG. 8 (b), the motion detection unit 9 corrects the displacement amount indicated by β in FIG. 8 (b) within a time Tb necessary for detecting a predetermined “shake” motion. By detecting a change from negative to positive and from negative to positive a plurality of times, it is detected that the “shake” operation has been performed. It is possible to detect the number of “shaking” movements from the number of detections and the direction of the “shaking” movements from the posture signal at the detection point. In this embodiment, the “swing” operation is detected based on the X-axis output. However, the “slap” operation is detected based on the Y-axis and Z-axis outputs. Also good.

Further, when the operation key 4 is pressed, the cursor control unit 15 notifies the central control unit 16 of the operation assigned to the instruction key Km where the cursor is located on the third key layout screen 35.

  When the fourth key arrangement screen 36 is displayed on the display unit 3, the cursor control unit 15 is based on the key arrangement information from the display control unit 14 and the posture vector R input from the coordinate conversion unit 8. The component in the cursor movement direction is extracted from the time, and the extracted component in the cursor movement direction is the time required to detect at least the action performed on the controller device 1 (the time Tb required to detect the “shake” action). Remember the above. In addition, when an input signal is input from the motion detection unit 9, the cursor control unit 15 receives a predetermined time before the input of the motion detection signal (when a motion detection signal indicating a “tap” operation is input, If a motion detection signal indicating a “shake” motion is input before the sample time, the component in the cursor movement direction in the posture vector R before the time Tb necessary to detect the “shake” motion is stored as threshold information. By determining whether or not the threshold value T <b> 0 stored in the unit 13 is less than the threshold value T <b> 0, the inclination of the operation device 1 in the cursor movement direction before the operation is performed on the operation device 1 is determined. Furthermore, when the cursor moving direction component in the posture vector R before the operation is performed on the controller device 1 is less than the threshold value T0, the cursor control unit 15 performs the first key arrangement screen 31 and the second key. In the arrangement screen 34 and the third key arrangement screen 35, the operation assigned to the instruction key Km where the cursor is located is notified to the central control unit 16, and the posture vector before the operation is performed on the controller device 1 is performed. When the component of the cursor movement direction in R is equal to or greater than the threshold value T0, the cursor is moved by one in the direction of the component of the posture vector R in the cursor movement direction.

  The central control unit 16 controls the audio output unit 18 to perform reproduction of the music data notified from the cursor control unit 15, and performs an operation notified from the cursor control unit 15 with respect to the display control unit 14 and the audio. This is executed by controlling the output unit 18. Further, when the operation key 4 is pressed in the power-off state, power-on control is performed, and when the operation key 4 is pressed for a predetermined time or more in the power-on state, the power-off control is performed. The power-off control may be executed by providing an instruction key to which a power-off operation is assigned on any of the operation screens.

An evaluation score obtained by evaluating the music data for each item is recorded.

  The audio output unit 18 is an audio player that reproduces music data recorded in the database 17 based on an instruction from the central control unit 16, and outputs an audio signal from an audio output terminal (not shown) such as a headphone that is not shown. Output to the device.

  The communication unit 43 has a function of transmitting and receiving information to and from the personal computer 30 via the connection unit 5. The communication unit 43 transmits information such as operations performed on the operation device 1 to the personal computer 30 and transmits information such as music data to the personal computer 30. Receive from. Further, the communication unit 43 monitors whether or not the connection unit 5 and the pin 23 of the cradle 20 are connected, that is, whether or not the operating device 1 is placed on the cradle 20. Is connected, that is, when the operating device 1 is placed on the cradle 20, a connection signal is output to the central control unit 16.

Next, the movement operation of the cursor on the first key layout screens 31 and 32 will be described in detail with reference to FIG.
FIG. 18 is a flowchart for explaining the cursor moving operation on the first key layout screen in the embodiment of the operating device according to the present invention.

  The display control unit 14 reads out the first key layout screens 31 and 32 from the screen storage unit 10 and displays them on the display unit 3 based on the control of the central control unit 16 (step A1). Operation screen specifying information for specifying the first key layout screens 31 and 32 is notified to the cursor control unit 15 (step A2).

Next, the coordinate conversion unit 8 calculates X-axis and Y-axis rotation angles θ _x and θ _y based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. (Step A3), the inclination of the controller device 1 from the first reference angle A is shown by referring to the first reference angle A (rotation angles θ _x1 , θ _y1 ) stored in the reference angle storage unit 42. Attitude vector R, that is, an angle θ _a indicating in which direction the controller device 1 is tilted from the first reference angle A, and a length r indicating the magnitude of the tilt angle of the controller device 1 from the first reference angle A, Is calculated (step A4).

  Next, the cursor control unit 15 specifies a current cell corresponding to the attitude vector R input from the coordinate conversion unit 8 based on the first cell information stored in the cell information storage unit 11 (step S1). A5) One of the first conversion tables stored in the conversion table storage unit 12 is specified based on the operation screen specifying information notified from the display control unit 14, and the specified first conversion table is used. The instruction key Km associated with the specified current cell is specified (step A6), and the cursor is moved to the specified instruction key Km (step A7). FIG. 15A shows a state in which the cells S1 and S2 of the first cell information are specified as the current cell by the attitude vector R calculated by the coordinate conversion unit 8, and the first key is shown in FIG. In the case of the array screen 31, the cells S1 and S2, which are current cells, are converted into the instruction key K1 by the first conversion table shown in FIG. 16A, and the instruction key K1 is displayed as shown in FIG. In the case of the first key layout screen 32 when the cursor is moved, the cells S1 and S2, which are current cells, are converted into the instruction key K1 by the first conversion table shown in FIG. ), The cursor is moved to the instruction key K1.

  Next, the cursor control unit 15 determines whether or not the operation key 4 has been pressed (step A8). If the operation key 4 has been pressed, the operation assigned to the instruction key where the cursor is located is centered. The central control unit 16 notifies the control unit 16 and executes the operation notified from the cursor control unit 15 by controlling the display control unit 14 and the audio output unit 18 (step A9), and the first key arrangement The cursor movement operation on the screens 31 and 32 is terminated.

If the operation key 4 is not pressed in step A8, the process returns to step A3, and the coordinate conversion unit 8 is output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7 based on the attitude signal. Then, rotation angles θ _x and θ _y of the X axis and Y axis are calculated.

Next, another example of the first cell information stored in the cell information storage unit 11 will be described in detail with reference to FIG.
19 is a diagram showing another example of cell information stored in the cell information storage unit shown in FIG.

The cell information to be stored in the cell information storage unit 11, as shown in FIG. 19 may also be composed of a plurality of cells divided based on the X-axis rotational angle theta _x and Y-axis rotation angle theta _y In this case, since the rotation angles θ _x and θ _y calculated by the coordinate conversion unit 8 may be output to the cursor control unit 15, it is not necessary to calculate the posture vector R by the coordinate conversion unit 8. In the example shown in FIG. 19, the eight cells S (m, n: m = 1, in which the Y-axis rotation angle θ _y is divided into m = 4 and the X-axis rotation angle θ _x is divided into m = 2. 2, 3, 4, n = 1, 2).

Next, an example in which a hysteresis characteristic is given to the movement of the cursor between the instruction keys on the first key layout screen 31 will be described in detail with reference to FIG.
FIG. 20 is a diagram showing a state of the current cell enlarged by the cursor control unit shown in FIG.

  In the cursor movement operation on the first key arrangement screen 31 described above, since the instruction key for moving (positioning) the cursor is determined by the current cell specified by the posture vector R, the first cell In the information, when the posture vector R is positioned on the substantially boundary line between the current cell and the adjacent cell, the cell specified as the current cell is changed by slight blurring, and the cursor moves between the adjacent instruction keys. There is a risk of going back and forth. Therefore, it is conceivable to provide a hysteresis characteristic for the movement of the cursor between the adjacent instruction keys to prevent the cursor from moving back and forth between the adjacent instruction keys due to slight tilting.

  In order to give a hysteresis characteristic to the movement of the cursor between the adjacent instruction keys, the cursor control unit 15 uses the posture vector R in the first cell information as shown in FIGS. 20 (a) and 20 (b). The specified current cell is expanded in the direction of the adjacent cell. In FIG. 20A, the cells S1 and S2, which are the current cells specified by the cursor control unit 15 by the posture vector R, are expanded in the direction of the adjacent cells 1, 1, cells 2, 2, and cells 4, 2. The state is shown. When the posture vector R is displaced from the state shown in FIG. 20A to the state shown in FIG. 20B, the cells 4 and 2 are specified as current cells by the cursor control unit 15, and the state shown in FIG. As shown, cell S4,2 which is the current cell is expanded in the direction of adjacent cells 1,2, cells 3,2, cells 4,1. Therefore, the boundary where the current cell transitions from the state shown in FIG. 20C (the state where the cells 4 and 2 are specified as the current cell) to the cells S1 and S2 is the current cell from the cells 1 and 2 to the cells 4 and 2. Is set to a position that is different from the boundary where the transition has occurred (a position that makes transition difficult), and the adjacent cell is not identified as the current cell by a slight tilt blur, so the cursor is adjacent by a slight tilt blur It is possible to prevent back and forth between the instruction keys.

Next, the movement operation of the music selection cursor on the music map screen 33 will be described in detail with reference to FIG.
FIG. 21 is a flowchart for explaining the movement operation of the music selection cursor on the music map screen in the embodiment of the operating device according to the present invention.

  When the display control unit 14 reads the music map screen 33 from the screen storage unit 10 and displays it on the display unit 3 based on the control of the central control unit 16 (step B1), the music map screen 33 displayed on the display unit 3 is displayed. The cursor control unit 15 is notified of the operation screen specifying information to be specified (step B2).

Next, the coordinate conversion unit 8 calculates X-axis and Y-axis rotation angles θ _x and θ _y based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. (Step B3), the inclination of the controller device 1 from the first reference angle A is shown by referring to the first reference angle A (rotation angles θ _x1 , θ _y1 ) stored in the reference angle storage unit 42. Attitude vector R, that is, an angle θ _a indicating in which direction the controller device 1 is tilted from the first reference angle A, and a length r indicating the magnitude of the tilt angle of the controller device 1 from the first reference angle A, Is calculated (step B4).

  Next, the cursor control unit 15 specifies a current cell corresponding to the posture vector R input from the coordinate conversion unit 8 based on the second cell information stored in the cell information storage unit 11 (step S1). B5), the movement amount and speed associated with the current cell specified using the second conversion table stored in the conversion table storage unit 12 are specified (step B6), and the movement specified in the direction of the attitude vector R The music selection cursor 37 is moved by the amount and speed (step B7). FIG. 14B shows a state in which the cell S2 of the second cell information is specified as the current cell by the attitude vector R calculated by the coordinate conversion unit 8. In this case, FIG. The movement amount and speed of the music selection cursor 37 are specified as L2 and A2 by the second conversion table shown in FIG.

  Next, the cursor control unit 15 determines whether or not the operation key 4 is pressed (step B8). When the operation key 4 is pressed, the music data included in the music selection cursor 37 is centrally controlled. The central control unit 16 controls the audio output unit 18 to reproduce the music data notified from the cursor control unit 15 (step B9), and the music selection cursor on the music map screen 33 is notified. The movement operation of 37 is finished.

If the operation key 4 is not pressed in step B8, the process returns to step B3, and the coordinate conversion unit 8 is output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7 based on the attitude signal. Then, rotation angles θ _x and θ _y of the X axis and Y axis are calculated.

Next, the movement operation of the key selection cursor on the second key layout screen 34 will be described in detail with reference to FIG.
FIG. 22 is a flowchart for explaining the movement operation of the key selection cursor on the second key layout screen in the embodiment of the operating device according to the present invention.

  When the display control unit 14 reads out the second key layout screen 34 from the screen storage unit 10 and displays it on the display unit 3 based on the control of the central control unit 16 (step C1), the display control unit 14 displays the second key layout screen 34 displayed on the display unit 3. The operation screen specifying information for specifying the key arrangement screen 34 is notified to the cursor control unit 15 (step C2).

Next, the coordinate conversion unit 8 calculates X-axis and Y-axis rotation angles θ _x and θ _y based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. (Step C3), the inclination of the controller device 1 from the first reference angle A is shown by referring to the first reference angle A (rotation angles θ _x1 , θ _y1 ) stored in the reference angle storage unit 42. Attitude vector R, that is, an angle θ _a indicating in which direction the controller device 1 is tilted from the first reference angle A, and a length r indicating the magnitude of the tilt angle of the controller device 1 from the first reference angle A, Is calculated (step C4).

  Next, the cursor control unit 15 specifies a current cell corresponding to the posture vector R input from the coordinate conversion unit 8 based on the second cell information stored in the cell information storage unit 11 (step S1). C5), the movement amount and the speed associated with the current cell specified using the second conversion table stored in the conversion table storage unit 12 are specified (step C6), and the movement specified in the direction of the posture vector R The key selection cursor 38 is moved by the amount and the speed (step C7), and the instruction key Km where the key selection cursor 38 is located is selected (step C8). In the second key layout screen 34, an instruction key area 39 corresponding to each instruction key Km is set, and the instruction key areas 39 are set to be adjacent to each other. The key selection cursor 38 is located in any one of the instruction key areas 39 corresponding to the instruction keys Km, and the instruction key Km corresponding to the instruction key area 39 where the key selection cursor 38 is located is selected. Become. Accordingly, as shown in FIG. 11, when it is desired to shift from the state in which the instruction key K23 is selected by the key selection cursor 38 to the state in which the instruction key K5 is selected, the instruction key K23 indicated by the arrow in FIG. By tilting the controller device 1 in the direction of the instruction key K5, the key selection cursor 38 can be moved on the straight line from the instruction key K23 toward the instruction key K5 with the shortest distance, and the instruction key K5 is selected in a short time. It becomes possible.

  Next, the cursor control unit 15 determines whether or not the operation key 4 has been pressed (step C9). If the operation key 4 has been pressed, it is assigned to the instruction key Km selected by the key selection cursor 38. The central control unit 16 notifies the central control unit 16 of the performed operation, and executes the operation notified from the cursor control unit 15 by controlling the display control unit 14 and the audio output unit 18 (step C10). The movement operation of the key selection cursor 38 on the second key layout screen 34 is terminated.

When the operation key 4 is not pressed in step C9, the process returns to step C3, and the coordinate conversion unit 8 is output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7 based on the attitude signal. Then, rotation angles θ _x and θ _y of the X axis and Y axis are calculated.

Next, the cursor movement operation on the third key layout screen 35 will be described in detail with reference to FIG.
FIG. 23 is a flowchart for explaining the cursor movement operation on the third key layout screen in the embodiment of the operating device according to the present invention.

  The display control unit 14 reads out the third key layout screen 35 from the screen storage unit 10 and displays it on the display unit 3 based on the control of the central control unit 16 (step D1). The key arrangement information of the key arrangement screen 35 is notified to the cursor control unit 15 (step D2).

Next, the coordinate conversion unit 8 calculates X-axis and Y-axis rotation angles θ _x and θ _y based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. (Step D3), the inclination of the controller device 1 from the first reference angle A is shown by referring to the first reference angle A (rotation angles θ _x1 , θ _y1 ) stored in the reference angle storage unit 42. Attitude vector R, that is, an angle θ _a indicating in which direction the controller device 1 is tilted from the first reference angle A, and a length r indicating the magnitude of the tilt angle of the controller device 1 from the first reference angle A, Is calculated (step D4).

  Next, the cursor control unit 15 extracts a component in the cursor movement direction from the posture vector R input from the coordinate conversion unit 8 based on the key arrangement information from the display control unit 14 (step D5). In the third key arrangement screen 35 shown in FIG. 12, since the instruction keys Km are arranged along the X axis, the display control unit 14 outputs key arrangement information indicating the X axis direction to the cursor control unit 15. .

  Next, the cursor control unit 15 determines whether or not the posture vector R component in the cursor movement direction is less than the threshold value T0 stored in the threshold value information storage unit 13 (step D6). As a result of steps D3 to D6, as shown in FIG. 17A, the posture vector R component in the cursor movement direction is less than the threshold T0, that is, the controller device 1 is set to the first reference angle A in the cursor movement direction. On the other hand, it is determined whether or not the inclination angle is less than the threshold value T0 (hereinafter referred to as the home position) while being kept almost horizontal.

  If the component of the posture vector R in the cursor movement direction is not less than the threshold T0 stored in the threshold information storage unit 13 in step D6, that is, if the controller device 1 is not kept at the home position, the cursor control unit 15 Then, it is determined whether or not the operation key 4 is pressed (step D7). If the operation key 4 is not pressed, the process returns to step D3. If the operation key 4 is pressed, the instruction selected by the cursor is selected. An operation assigned to the key Km is notified to the central control unit 16, and the central control unit 16 executes an operation notified from the cursor control unit 15 by controlling the display control unit 14 and the audio output unit 18 ( Step D8), the movement operation of the cursor is terminated.

When the component of the posture vector R in the cursor movement direction is less than the threshold T0 stored in the threshold information storage unit 13 in step D6, that is, when the controller device 1 is kept at the home position, the coordinate conversion unit 8 Calculates the rotation angles θ _x and θ _y of the X axis and the Y axis based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7 (step D9). By combining the rotation angles θ _x and θ _y , the angle θ _a indicating the direction in which the controller device 1 is tilted and the length r indicating the magnitude of the tilt angle of the controller device 1 are represented. Attitude vector R is calculated (step D10).

  Next, the cursor control unit 15 extracts a component in the cursor movement direction from the posture vector R input from the coordinate conversion unit 8 based on the key arrangement information from the display control unit 14 (step D11), and the cursor movement direction. It is determined whether or not the component of the posture vector R is equal to or greater than a threshold T0 stored in the threshold information storage unit 13 (step D12). As a result of steps D9 to D12, as shown in FIG. 17B, when the component of the posture vector R in the cursor movement direction is equal to or greater than the threshold value T0, the controller device 1 is tilted in the cursor movement direction and the tilt angle is the threshold value T0. It is determined whether or not this is the state.

  If the component of the posture vector R in the cursor movement direction is not equal to or greater than the threshold T0 stored in the threshold information storage unit 13 in step D12, that is, if the controller device 1 is maintained at the home position, the cursor control unit 15 Then, it is determined whether or not the operation key 4 is pressed (step D13). If the operation key 4 is not pressed, the process returns to step D9. If the operation key 4 is pressed, the instruction selected by the cursor is selected. An operation assigned to the key Km is notified to the central control unit 16, and the central control unit 16 executes an operation notified from the cursor control unit 15 by controlling the display control unit 14 and the audio output unit 18 ( Step D14), the movement operation of the cursor is terminated.

  When the component of the posture vector R in the cursor movement direction is greater than or equal to the threshold T0 stored in the threshold information storage unit 13 in step D12, that is, when the controller device 1 is tilted by a predetermined amount or more in the cursor movement direction. The cursor control unit 15 moves one cursor in the direction of the component of the posture vector R in the cursor movement direction (step D15), and returns to step D3.

  As a result, on the third key layout screen 35 in which the cursor is positioned on the instruction key K7 as shown in FIG. 12, the operating device 1 is moved in the direction in which the cursor is to be moved from the home position (any of the X-axis directions). By tilting the threshold T0 or more, the cursor is moved by one to either the instruction key K6 or the instruction key K8 adjacent to the left and right. After the cursor is moved to the instruction key K6 or the instruction key K8, the cursor is not moved further unless the operating device 1 is returned to the home position. Therefore, the instruction key K6 or the instruction key adjacent to the left and right from the instruction key K7. It becomes possible to reliably move the cursor to K8.

Next, another embodiment for controlling the cursor movement on the third key layout screen 35 using two threshold values will be described in detail with reference to FIG.
FIG. 24 is a diagram illustrating another example of threshold information stored in the threshold information storage unit illustrated in FIG.

  In another embodiment in which the cursor movement is controlled using two threshold values, referring to FIG. 24, the length r of the posture vector R calculated by the AD conversion unit 7 in the threshold information storage unit 13, that is, the controller device 1. The threshold value T0 of the inclination angle and the threshold value T1 (threshold value T0> threshold value T1) are stored, and in step D6 described above, the cursor control unit 15 determines that the component of the posture vector R in the cursor movement direction is the threshold value information storage unit. 13 is configured to determine whether or not the threshold value is less than the threshold value T1 stored.

  As a result, as shown in FIG. 24A, the cursor is moved to the instruction key Km adjacent to the home position when the controller device 1 is held below the threshold T1, as shown in FIG. Thus, the cursor is moved when the controller device 1 is tilted from the home position in the cursor movement direction by a threshold T0 or more. Accordingly, the vibration in a state where the controller device 1 is tilted by about the threshold value T0 in the cursor movement direction causes the controller device to change many times between the home position and the state where the controller device 1 is tilted by the threshold value T0 or more, and the cursor is not intended. It is possible to prevent going forward.

Next, the cursor movement operation on the fourth key layout screen 36 will be described in detail with reference to FIG.
FIG. 25 is a flowchart for explaining the cursor moving operation on the fourth key layout screen in the embodiment of the operating device according to the present invention.

  When the display control unit 14 reads out the fourth key layout screen 36 from the screen storage unit 10 and displays it on the display unit 3 based on the control of the central control unit 16 (step E1), the display control unit 14 displays the fourth key display screen displayed on the display unit 3. The key arrangement information on the key arrangement screen 36 is notified to the cursor control unit 15 (step E2).

Next, the coordinate conversion unit 8 calculates X-axis and Y-axis rotation angles θ _x and θ _y based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. (Step E3), the inclination of the controller device 1 from the first reference angle A is shown by referring to the first reference angle A (rotation angles θ _x1 , θ _y1 ) stored in the reference angle storage unit 42. Attitude vector R, that is, an angle θ _a indicating in which direction the controller device 1 is tilted from the first reference angle A, and a length r indicating the magnitude of the tilt angle of the controller device 1 from the first reference angle A, Is calculated (step E4).

  Next, the cursor control unit 15 extracts a component in the cursor movement direction from the posture vector R input from the coordinate conversion unit 8 based on the key arrangement information from the display control unit 14 (step E5). In the case of the fourth key arrangement screen 36 shown in FIG. 13, since the instruction keys Km are arranged along the Y axis, the display control unit 14 displays the key arrangement information indicating the Y axis direction as the cursor control unit 15. The cursor control unit 15 extracts a component Ry of the posture vector R in the Y-axis direction as shown in FIG.

  Next, the cursor control unit 15 determines whether or not an operation detection signal is input from the operation detection unit 9 (step E6). If no operation detection signal is input from the operation detection unit 9, step E3 is performed. Return to.

  When the motion detection signal is input from the motion detection unit 9 in step E6, the cursor control unit 15 indicates that the component in the cursor movement direction in the posture vector R a predetermined time before the input of the motion detection signal is the threshold information storage unit. It is determined whether or not the threshold value T0 is less than 13 (step E7). That is, in step E7, when the operation device 1 performs a “tap” or “shake” operation, the operation device 1 moves in the cursor movement direction in the posture vector R as shown in FIG. A state in which the component is less than the threshold value T0, that is, a state in which the controller device 1 is kept horizontal with respect to the first reference angle A in the cursor movement direction and the inclination angle is less than the threshold value T0 (hereinafter referred to as a home position). ) Or not.

  When the component in the cursor movement direction in the posture vector R is less than the threshold value T0 stored in the threshold value information storage unit 13 in step E7, that is, when the controller device 1 is maintained at the home position, the cursor control unit 15 Notifies the central control unit 16 of the operation assigned to the instruction key Km selected by the cursor, and the central control unit 16 displays the operation notified from the cursor control unit 15 by the display control unit 14 and the audio output unit 18. (Step E8), and the cursor movement operation is terminated.

  Thus, the operation assigned to the instruction key Km selected by the cursor is performed by performing the operations of “tapping” and “shaking” on the operation device 1 while the operation device 1 is maintained at the home position. Can be executed.

  When the component in the cursor movement direction in the posture vector R is not less than the threshold value T0 stored in the threshold value information storage unit 13 in step E7, as shown in FIG. 17B, that is, the controller device 1 is kept at the home position. If not, the cursor control unit 15 moves one cursor in the direction of the component in the region arrangement direction in the posture vector R (step E9), and returns to step E3.

  As a result, on the fourth key layout screen 36 where the cursor is positioned on the instruction key K3 as shown in FIG. 13, the operating device 1 is moved in the direction in which the cursor is to be moved from the home position (any of the Y-axis directions). When the controller device 1 is “tapped” or “swinged” while being tilted by the threshold T0 or more, the cursor is moved by one to the instruction key K2 or the instruction key K4 adjacent vertically. Will be. It should be noted that by using the tilt at the moment when the “shaking” action is detected, it is possible to move only one cursor in the direction in which the “shaking” action is shaken.

  In the present embodiment, the example in which the instruction key Km is arranged in the Y-axis direction as in the fourth key arrangement screen 36 has been described. However, the arrangement direction of the instruction key Km is not limited, for example, diagonally You may make it arrange in order.

  In the present embodiment, when the operation of “tapping” or “shaking” performed on the controller device 1 is detected, either the cursor is moved or the operation is executed according to the tilt of the controller device 1. However, when the first predetermined action of “tapping” or “shaking” performed on the controller device 1 is detected, the cursor is moved and the first operation performed on the controller device 1 is performed. When a second predetermined motion of “shaking” or “tapping” different from the predetermined motion of 1 is detected, the operation assigned to the instruction key Km selected by the cursor may be executed. In this case, the cursor movement order is determined in advance on the fourth key layout screen 36, and the cursor control unit 15 detects in advance a first predetermined action performed on the controller device 1. The cursor is moved in a predetermined movement order.

Next, the operation in a state where the operating device 1 is placed on the cradle 20 will be described in detail with reference to FIGS. 26 and 27. FIG.
FIG. 26 is a flowchart for explaining the reference angle switching operation when the operating device according to the present invention is placed on the cradle, and FIG. 27 is a state in which the operating device shown in FIG. 1 is placed on the cradle.

  The communication unit 43 monitors the connection between the connection unit of the controller device 1 and the pin 23 of the cradle 20, that is, the connection of the controller device 1 to the cradle 20 (step F1), and the controller device 1 connects to the cradle 20. Then, a cradle connection signal is output to the coordinate conversion unit 8 via the central control unit 16 and the cursor control unit 15.

The coordinate conversion unit 8 to which the cradle connection signal is input switches the attitude reference of the controller device 1 to the second reference angle B (rotation angles θ _x2 , θ _y2 ) stored in the reference angle storage unit 42 (step F2). ). Next, the coordinate conversion unit 8 calculates X-axis and Y-axis rotation angles θ _x and θ _y based on the attitude signal output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. (Step F3). Furthermore, the coordinate conversion unit 8 refers to the second reference angle B (rotation angles θ _x2 , θ _y2 ) stored in the reference angle storage unit 42, thereby determining the inclination of the controller device 1 from the second reference angle B. The orientation vector R shown, that is, the angle θ _a indicating in which direction the controller device 1 is tilted from the second reference angle B, and the length r indicating the magnitude of the tilt angle of the controller device 1 from the second reference angle B Is calculated (step F4), and the calculated attitude vector R via the cursor control unit 15, the central control unit 16, and the communication unit 43 is transmitted as an operation signal to the personal computer 30 (step F5). . Hereinafter, at each sampling time in the AD conversion unit 7, the coordinate conversion unit 8 repeats the operations from Step F3 to Step F5, and the controller device 1 is moved as shown in FIGS. By tilting while connected to the cradle 20, the personal computer 30 can be operated. In addition to operating the personal computer 30 with the operating device 1 connected to the cradle 20, the first key layout screens 31 and 32, the music map screen 33, the second key layout screen 34 of the operating device 1, The cursors on the third key arrangement screen 35 and the fourth key arrangement screen 36 may be moved.

Next, the drift correction operation in a state where the controller device 1 is placed on the cradle 20 will be described in detail with reference to FIGS.
FIG. 28 is a perspective view showing a state where the cradle on which the operating device shown in FIG. 1 is placed is placed on the slope, and FIG. 29 explains the drift correction operation performed in the coordinate conversion unit shown in FIG. FIG. 30 is a diagram illustrating an example of drift correction performed by the coordinate conversion unit illustrated in FIG. 4.

  As shown in FIG. 28, the cradle 20 is configured so that the mounting table 21 always has the same posture even when the support table 22 is placed on a slope. If it is placed on the head, it will always be kept in the same posture unless a force is applied from the outside.

  Therefore, in the present embodiment, drift correction of the attitude signal output from the tilt angle detection unit 6 is performed in a state where the controller device 1 is placed on the cradle 20. The drift is an attitude signal output from the tilt angle detection unit 6 for some reason, that is, an output voltage is deviated from the tilt angle detection unit 6, and output from the tilt angle detection unit 6 by the drift correction operation. A drift correction value for correcting the voltage deviation is obtained.

  First, the communication unit 43 monitors the connection between the connection unit of the controller device 1 and the pin 23 of the cradle 20, that is, the connection of the controller device 1 to the cradle 20 (step G1). Is connected to the coordinate conversion unit 8 via the central control unit 16 and the cursor control unit 15.

  The coordinate conversion unit 8 to which the cradle connection signal is input sets the variable n to “0” (step G2), and is output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. When the change in (output voltage) is monitored (step G3) and the posture signal does not change, that is, when there is no movement in the posture of the controller device 1 placed on the cradle 20, the cursor control unit 15 uses the variable n. Is incremented (step G4). Note that the change of the posture signal in step G3 is performed every sampling time in the AD conversion unit 7.

  Next, the coordinate conversion unit 8 determines whether or not the incremented variable n has reached a predetermined number (step G5). If the variable n has not reached the predetermined number, that is, When the state in which the posture of the controller device 1 does not move does not continue for a predetermined time, the process returns to step G2.

  If the variable n reaches a predetermined number in step G5, that is, if it is detected that the posture of the controller device 1 placed on the cradle 20 has not moved for a predetermined time, the coordinates are The conversion unit 8 determines whether or not there is a difference between the input posture signal and the reference posture signal stored in advance in the reference angle storage unit 42 (step G6), and the input posture signal and the reference posture If there is no deviation from the signal, the drift correction operation is terminated without performing drift correction. If there is a deviation between the input attitude signal and the reference attitude signal, the input attitude signal is used as the reference attitude signal. The value to be corrected is calculated as a drift correction value (step G7), the calculated drift correction value is stored in the reference angle storage unit 42, and the drift correction operation is terminated. For example, when the controller device 1 is placed on the cradle 20, the display surface of the display unit 3 becomes vertical. Therefore, the X-axis tilt angle is 0 °, the Y-axis tilt angle is −90 °, and the Z-axis tilt. Each angle is −90 °, and the reference attitude signals are X axis: 1.5 V, Y axis: 1.5 V, and Z axis: 2.2 V as shown in FIG. 30. However, when the posture signal input to the coordinate conversion unit 8 is X axis: 1.7 V, Y axis: 1.4 V, and Z axis: 2.1 V, the input posture signal is used as a reference posture signal. The correction values X axis: −0.2 V, Y axis: +0.1 V, and Z axis: +0.1 V are calculated as drift correction values and stored in the reference angle storage unit 42.

When the drift correction value is stored in the reference angle storage unit 42 by the above drift correction operation, the coordinate conversion unit 8 is output from the tilt angle detection unit 6 and converted into a digital signal by the AD conversion unit 7. The attitude signal is corrected based on the drift correction value, and the X-axis and Y-axis rotation angles θ _x and θ _y and the attitude vector R are calculated based on the corrected attitude signal, respectively, so that the input attitude signal drifts The inclination of the controller device 1 can be detected with high accuracy.

As described above, according to the present embodiment, based on the design attitude signal output from the tilt angle detection unit 6 in the state where the controller device 1 is placed on the cradle 20 in the reference angle storage unit 42. In this state, the posture signal output from the tilt angle detection unit 6 is compared with the reference posture signal and stored as a tilting posture signal, and the coordinate conversion unit 8 has the operating device 1 mounted on the cradle 20. When the attitude signal output from the set inclination angle detection unit 6 and the reference attitude signal are different, a drift correction value for correcting the attitude signal output from the inclination angle detection unit 6 to the reference attitude signal is calculated to obtain the reference angle When the drift correction value is stored in the storage unit 42 and stored in the reference angle storage unit 42, the posture signal output from the tilt angle detection unit 6 is corrected with the drift correction value, and based on the corrected posture signal. The tilt of the operating device 1 By configured to calculate the drift occurring in the output of the tilt angle detecting unit 6 can be corrected, there is an effect that it is possible to detect the correct inclination of the operation device 1.

  In addition, according to the present embodiment, when the operation device 1 for the cradle 20 is detected by the communication unit 43 and the posture signal output from the tilt angle detection unit 6 continues for a predetermined time, there is no change. The coordinate conversion unit 8 is configured to calculate the drift correction value, so that the drift correction can be performed after the reference posture of the controller device 1 is determined, and thus the correct drift correction value is calculated. There is an effect that can be.

  In addition, the cradle 20 on which the operating device 1 of the present embodiment is mounted is configured by a mounting table 21 on which the operating device 1 is mounted and a support table 22 that supports the mounting table 21 so as to be swingable. By configuring the mounting table 21 so as to always maintain the same posture even when the support table 22 is placed on the slope, the reference posture of the operating device 1 mounted on the cradle 20 is made constant. And the correct drift correction value can be calculated.
