Referring to FIG. A display unit 3 is provided on the main surface portion, and an operation key 4 is provided on the right side surface portion of the housing 2, and in the housing 2, referring to FIG. 2, an inclination angle detection unit 6 and an AD conversion unit. 7, a coordinate conversion unit 8, an operation detection unit 9, a screen storage unit 10, a cell information storage unit 11, a conversion table storage unit 12, a display control unit 14, a cursor control unit 15, and a central control unit 16, a database 17, and an audio output unit 18.

  The display unit 3 is a display means such as a liquid crystal display (LCD) and displays various title information such as the title name of the music data to be played back, bibliographic data such as the artist name, playback time, etc. Various instruction keys such as adjustment, music data search, and music data reproduction instruction are displayed. In the present embodiment, the guide information and the instruction key are displayed on the same screen on the display unit 3, but other display means such as a liquid crystal display (LCD) is provided on the main surface of the operation device 1. The guidance information and the instruction key may be displayed on separate display means.

  The operation key 4 functions as a power key for instructing power on / off and an execution key for instructing execution of a function (instruction key) selected by the user. The operation key 4 is a right side surface portion of the housing 2. 3, i.e., as shown in FIG. 3, the main surface portion on which the display unit 3 is provided is located on the upper side, and the controller device 1 is disposed at a position where it can be operated with the thumb with the right hand held.

  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 portion 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 posture signal output from the tilt angle detection unit 6 into a digital signal and outputs the digital signal to the coordinate conversion unit 8. The coordinate conversion unit 8 uses the X-axis and Y-axis based on the input posture signal. The respective rotation angles θ _x and θ _y of the controller device 1 centered on the axes are calculated. 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. The coordinate transformation unit 8, the calculated rotation angle theta _x, to synthesize the theta _y, as shown in FIG. 5, the angle theta _a indicating whether the operation device 1 is tilted in any direction, the operation device 1 A posture vector R represented by a length r indicating the magnitude of the tilt angle is calculated and output to the cursor control unit 15.

  The motion detection unit 9 detects “slap” and “shake” motions performed on the controller device 1 and performs a predetermined number of “slap” or “shake” at a predetermined time interval. When the operation “is detected, an operation switching signal is output to the cursor control unit 15.

  FIG. 6A 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. 6B, 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 that becomes an instantaneous large inclination shown by A in FIG. 6B 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.

  FIG. 7A shows an example of a posture signal output from the tilt angle detection unit 6 when a “shake” operation is performed on the controller device 1. The X axis, the Y axis, and the Z axis are shown in FIG. 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. 7 (b), the motion detection unit 9 corrects the displacement amount indicated by β in FIG. 7 (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. In this embodiment, the “swing” operation is detected based on the output of the X axis. However, the “slap” operation is detected based on the outputs of the Y axis and the Z axis. Also good.

  When power is turned on by pressing the operation key 4, the display control unit 14 reads out the designated operation screen 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 3). A1), the operation screen specifying information for specifying the operation screen displayed on the display unit 3 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), by combining the calculated rotation angles θ _x and θ _y , an angle θ _a indicating which direction the controller device 1 is tilted and a length indicating the magnitude of the tilt angle of the controller device 1 A posture vector R represented by “r” is calculated (step A4), and the calculated posture vector R is output to the cursor control unit 15.

  Next, the cursor control unit 15 specifies the current cell corresponding to the posture vector R input from the coordinate conversion unit 8 based on the cell information stored in the cell information storage unit 11 (step A5), The conversion table 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 is converted into an instruction key associated with the specified current cell using the specified conversion table.

  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).

  The display control unit 14 determines whether or not the operation notified from the cursor control unit 15 involves switching of the operation screen, that is, whether or not a new operation screen is displayed (step A10). Returning to step A1, a new operation screen is read from the screen storage unit 10 and displayed on the display unit 3.

Also, when the operation key 4 is not pressed in step A8 and when the operation screen is not switched in step A10, the process returns to step A3, and the coordinate conversion unit 8 is output from the tilt angle detection unit 6 and AD Based on the attitude signal converted into a digital signal by the conversion unit 7, rotation angles θ _x and θ _y of the X axis and the Y axis are calculated.

  The operation device 1 according to the present embodiment is configured such that various operations are performed based on the attitude signal from the tilt angle detection unit 6, and a predetermined operation that is determined in advance by the operation detection unit 9 is detected. When an operation based on the posture signal is invalidated and the operation based on the posture signal is invalidated and a predetermined motion is detected in advance by the motion detection unit 9, the operation based on the posture signal is validated. The

The operation invalidation operation for invalidating the operation based on the attitude signal by a predetermined operation will be described in detail with reference to FIG.
FIG. 12 is a flowchart for explaining the operation invalidation operation in the embodiment of the operating device according to the present invention.

  When the power is turned on by pressing the operation key 4, the operation detection unit 9 sets the variable n to “0” (step B 1) and detects a predetermined operation performed on the operation device 1. Is monitored (step B2), and when a predetermined operation is detected, a time measurement is started (step B3) and the variable n is incremented (step B4). In the present embodiment, the “tapping” or “shaking” operation performed on the controller device 1 is set as a predetermined operation.

  Next, the motion detector 9 determines whether or not a predetermined time (predetermined time + α) has elapsed since the start of counting in step B3 (step B5), and the predetermined time + α has elapsed since the start of counting. If so, the process returns to step B1. In the present embodiment, the time width when the predetermined operation is received at predetermined time intervals is (2α), and the predetermined operation is performed between (predetermined time−α) and (predetermined time + α). A predetermined operation is accepted as a predetermined time interval.

  If (predetermined time + α) has not elapsed since the start of counting in step B5, the motion detector 9 determines whether or not the variable n has reached a predetermined number (step B6). If the variable n has not reached the predetermined number, the detection of the predetermined operation performed on the controller device 1 is monitored (step B7). If the predetermined operation is not detected, the process returns to step B5 to perform the predetermined operation. If it has been detected, it is determined whether or not the time at which the predetermined action is detected has passed (predetermined time-α) (step B8), and if it has elapsed, it is determined that the predetermined action has been performed at predetermined time intervals. Then, the process returns to step B3, but if it has not elapsed, it is determined that the predetermined operation is not performed at predetermined time intervals, and the process returns to step B5.

  When the variable n reaches a predetermined number in step B6, that is, when a predetermined number of predetermined motions are detected at predetermined time intervals, the motion detection unit 9 outputs an operation switching signal to the cursor control unit 15, The cursor control unit 15 to which the switching signal is input invalidates the operation based on the posture signal (step B9). As a method of invalidating the operation based on the posture signal, the operation of the coordinate conversion unit 8 may be stopped. In the cursor control unit 15, various methods based on the posture vector R input from the coordinate conversion unit 8 may be used. The operation may not be performed.

  Next, the motion detection unit 9 sets the variable n to “0” (step B10), and monitors detection of a predetermined motion performed on the controller device 1 (step B11). Is detected (step B12), and the variable n is incremented (step B13). In the present embodiment, the “tapping” or “shaking” operation performed on the controller device 1 is set as a predetermined operation.

  Next, the motion detection unit 9 determines whether or not a predetermined time (predetermined time + α) has elapsed since the start of counting in step B12 (step B14), and the predetermined time + α has elapsed since the start of counting. If so, the process returns to step B10. If (predetermined time + α) has not elapsed since the start of counting in step B14, the motion detection unit 9 determines whether or not the variable n has reached a predetermined number (step B15). When the variable n has not reached the predetermined number, the detection of the predetermined operation performed on the controller device 1 is monitored (step B16), and when the predetermined operation is not detected, the process returns to step B14 to perform the predetermined operation. If it has been detected, it is determined whether or not the time during which the predetermined action is detected has passed (predetermined time-α) (step B17). If it has elapsed, it is determined that the predetermined action has been performed at predetermined time intervals. Then, the process returns to step B12, but if it has not elapsed, it is determined that the predetermined operation is not performed at predetermined time intervals, and the process returns to step B14.

  When the variable n reaches a predetermined number in step B15, that is, when a predetermined number of predetermined motions are detected at predetermined time intervals in the state where the operation based on the posture signal is invalidated, the motion detection unit 9 When the operation switching signal is output to the cursor control unit 15 and the operation based on the posture signal is invalidated, the cursor control unit 15 to which the operation switching signal is input enables the operation based on the posture signal (step B18), returning to step B1.

  In this embodiment, when a predetermined number of predetermined motions are detected at predetermined time intervals, the operation based on the posture signal is invalidated or validated. However, the posture signal is detected by one predetermined motion. The operation based on the posture signal may be invalidated or the operation based on the posture signal may be validated. Further, the number of predetermined operations when the operation based on the posture signal is invalidated and the operation based on the posture signal is validated. The predetermined number of operations may be the same or different.

  Further, by changing the predetermined interval for each number of times, such as 1 second for the first time and 3 seconds for the second time, an input of a predetermined operation having a predetermined rhythm may be detected. This predetermined rhythm may be registered by, for example, having the user perform a predetermined action with an actual rhythm.

  Further, in the present embodiment, when a predetermined number of predetermined motions are detected at predetermined time intervals, the operation based on the posture signal is invalidated or enabled. However, the operation based on the posture signal is disabled. The predetermined operation for performing the operation based on the posture signal and the predetermined operation for validating the operation based on the posture signal may be the same operation, for example, the “tap” operation, and the predetermined operation for invalidating the operation based on the posture signal The operation based on the posture signal is enabled with the operation different from the predetermined operation when the operation based on the posture signal is enabled, for example, the predetermined operation when the operation based on the posture signal is invalidated. The predetermined operation at the time may be a “shake” operation.

  Further, in this embodiment, when a predetermined number of predetermined motions are detected at predetermined time intervals, the operation based on the attitude signal is invalidated or validated without inquiring the user. When a predetermined number of predetermined motions are detected at predetermined time intervals, the voice guidance means guides the invalidation or validation of the operation based on the posture signal, and the further predetermined motion detects the operation based on the posture signal. You may make it invalidate or validate.

  As described above, according to the present embodiment, predetermined motions performed on the controller device 1 by the motion detector 9, for example, “tap” motion and “shake” motion based on the posture signal. The cursor control unit 15 is configured to invalidate the operation based on the posture signal when the motion detection unit 9 detects the predetermined motion, thereby performing the predetermined operation on the controller device 1. The operation based on the tilt of the controller device 1 can be invalidated without requiring a physical switch, and when the controller device 1 is placed on a table or the like, the controller device 1 is placed vertically in a pocket or bag. In this case, it is possible to prevent an unintended instruction key Kp from being selected.

  Furthermore, according to the present embodiment, when the operation is invalidated or validated based on the attitude signal, a predetermined number of predetermined motions are detected at predetermined time intervals by the motion detection unit 9. By configuring so as to switch, there is an effect that it is possible to reliably identify the action of the user instructing the switching of the operation.
