Therefore, these descriptions will not be repeated.

First Embodiment
<Device configuration>
FIG. 1 is a schematic diagram illustrating an example of an appearance of a mobile phone device 100 as an example of a terminal device having a call function according to the present embodiment. Referring to FIG. 1, a mobile phone device 100 includes a display device and a touch panel 13 as an example of an operation device on one side. The surface on which the touch panel 13 is disposed is taken as the front of the mobile phone device 100.

  Further, a microphone 14 as an example of a voice input device and a speaker 15 as an example of a voice output device are arranged on the front surface of the mobile phone device 100. The audio output device is not limited to a speaker, and may be an audio output by vibration of the touch panel 13, for example.

  FIG. 2 is a block diagram showing an example of the hardware configuration of mobile telephone apparatus 100. Referring to FIG. Referring to FIG. 2, mobile phone device 100 includes a central processing unit (CPU) 10 for controlling the entire device, a read only memory (ROM) 11 for storing a program executed by CPU 10, and a CPU 10. And a RAM (Random Access Memory) 12 for storing various data as a work area when executing the program.

  Furthermore, as shown in FIG. 1, the mobile phone device 100 includes a touch panel 13, a microphone 14, and a speaker 15.

  As an example of the operation device, the touch panel 13 includes a start button 131 that is a touch-type button for instructing the start of a call and an end button 132 that is a touch-type button for instructing the end of the call. . The touch type button is not a physical press but a button that accepts an operation by touch.

  The start button 131 and the end button 132 may not always be displayed on the touch panel 13. That is, the start button 131 may be displayed on the touch panel 13 when there is an incoming call. The end button 132 may be displayed on the touch panel 13 when the call starts.

  Furthermore, the mobile telephone device 100 includes a sensor 16 and a communication unit 17. The communication unit 17 controls telephone communication with the mobile phone device 100. The sensor 16 detects a posture taken by the user of the mobile phone device 100 using the mobile phone device 100.

<Operation summary>
When making a call using the mobile phone device 100 according to the present embodiment, the user brings the speaker 15 disposed on the front of the mobile phone device 100 into contact with or near the ear or near the ear. Since the touch panel 13 is arranged on the front surface of the mobile phone device 100, an ear, a cheek, or a hand may touch the touch panel 13 during a call. In particular, when the touch panel 13 itself functions as the speaker 15, the touch panel 13 touches the user's ear or cheek during a call.

  Since the end button 132 for instructing the end of the call is arranged on the touch panel 13, if the user's ear, cheek or hand touches the touch panel 13 during the call, the end button 132 may be erroneously operated. . In particular, when the touch panel 13 itself functions as the speaker 15, the possibility of such an erroneous operation is increased.

  Therefore, when the user starts a call on the mobile telephone device 100, the mobile telephone device 100 according to the present embodiment invalidates (locks) the operation of the end button 132 to prevent an erroneous operation during the call.

  FIGS. 3A and 3B are diagrams showing an example of the transition of the screen display when the mobile telephone device 100 receives a call. When a call arrives at the mobile phone device 100, the touch panel 13 displays a screen shown in FIG. The screen in FIG. 3A includes a start button 131 that is a touch button for the user to instruct the start of a call.

  When a user starts a call by operating the start button 131 on the screen of FIG. 3A, a diagram for informing the touch panel 13 that the operation of the end button 132 is invalidated (locked). The screen 3 (B) is displayed. The screen in FIG. 3B indicates that the operation of the end button 132 is invalidated (locked) by, for example, the end button 132 being grayed out. Preferably, the screen in FIG. 3B may include a button for instructing unlocking.

  FIG. 4 is a diagram for explaining an operation outline of the mobile telephone device 100 according to the present embodiment. Referring to FIG. 4, when an incoming call is received, mobile phone apparatus 100 displays start button 131 on touch panel 13, and receives a call start instruction from the user (step S1). When an instruction to start a call is issued and it is detected that the user has performed an operation to take a posture for call start as the first operation, the mobile phone device 100 invalidates the operation of the end button 132 ( Lock) (step S2). The action of taking a posture to start a call is, as an example, an action of taking the mobile telephone device 100 in a bag, in a pocket or on a desk and twisting it to the ear. The portable telephone device 100 locks the end button 132 when it detects that this operation has been performed.

  In other words, the cellular phone device 100 does not lock the end button 132 from when the start button 131 is operated until it is detected that the user has taken the posture for starting a call. As a result, when the user has instructed to start a call, but wants to end the call before starting the call, for example, by confirming the call destination, the end button 132 can be operated.

  Then, the mobile phone device 100 locks the end button 132 when it is detected that the user before the start of the call, which is the input / output of voice, takes a posture for the start of the call. Thus, it is possible to prevent the user from touching the end button 132 when the user places the portable telephone apparatus 100 on his / her ear and touching the end button 132 for erroneous operation.

  Note that the operation of taking a posture for starting a call may be set for each user. This is because the normal usage and frequency of use of the mobile phone device 100 are different for each user, and the attitude for starting a call and the operation for taking the attitude are different. For example, when the user puts the portable telephone apparatus 100 in the side pocket normally, when the portable telephone apparatus 100 is put on the ear as the posture for the start of a call, the operation of taking the posture for the start of the communication is It takes out of the pocket and twists it in only one direction or two directions to hit the ear. Also, for example, when the user is viewing the output of content such as music from the mobile phone device 100 with the earphone, the user takes out the mobile phone device 100 from the pocket or bag and touches the start button 131 as a posture for call start. In the case of returning the cellular phone device 100 again, the operation of taking a posture for call start is an operation of taking out from the pocket or the bag, making it horizontal once (or almost horizontal), and then restoring it. Therefore, preferably, after performing a predetermined operation on the mobile phone device 100, the mobile phone device 100 takes the attitude that is desired by the user, by performing an operation for taking an attitude for starting a call. A calculated value (threshold value) for detecting an action may be set.

  The cellular phone device 100 invalidates the operation to the end button 132 by detecting that the operation for taking the posture for starting the call, which is the first operation, is performed after the start button 131 is operated. By doing so, it is possible to prevent the end button 132 from being erroneously operated during an operation such as carrying the cellular phone device 100 to the ear or touching it to the ear after the user performs a button operation to start a call.

  The cellular phone device 100 uses the sensor 16 to detect an operation in which the user takes a posture for starting a call. As the sensor 16, for example, a gyro sensor which is an example of a sensor for detecting angular velocity can be used. In the following description, it is assumed that the sensor 16 is a gyro sensor.

  FIG. 5 shows the x-, y-, and z-directions of the mobile phone device 100 in the x-, y-, and z-directions by the sensor 16 mounted on the mobile phone device 100 when the mobile phone device 100 in the posture used in front view is lifted by twisting 90 °. It is a figure showing the time passage of output. Referring to FIG. 5, the output of sensor 16 that is a gyro sensor shows a significant peak at time P in each of the x, y, and z directions. The detection result of FIG. 5 indicates that a twisting operation in each direction is applied to the mobile phone device 100 at time P. In other words, the detection result in FIG. 5 indicates that at time P, an operation of bringing the lifted portable telephone device 100 closer to the ear is added, that is, the user of the portable telephone device 100 takes a posture for call initiation. Indicates that the operation has been performed.

  Therefore, as shown in FIG. 5, threshold values T1 and T2 [rad / s] of output values in each direction are set in advance, and an output exceeding the threshold values T1 and T2 is detected. Thus, the mobile phone device 100 can detect that the user has performed an action to take a posture for starting a call. The threshold values T1 and T2 may be determined experimentally and stored in advance in the mobile phone device 100. Alternatively, the user of the mobile telephone device 100 operates to take a posture for speech start using the actual mobile telephone device 100, and the mobile telephone device 100 generates a threshold based on the output of the sensor 16 obtained from the operation. T1 and T2 may be set and stored.

  Preferably, after the start button 131 is operated, the mobile telephone device 100 detects an operation of taking a posture for call start based on a sensor signal from the sensor 16 and invalidates the operation on the end button 132. Later, when it is detected that the user has performed an operation of taking a posture for call termination as the second operation, the invalidation is released. The action of taking the attitude for ending the call is, as an example, a reverse operation of the action of taking the attitude for starting the call, which is the first action. When the second operation is the above operation, the mobile telephone device 100 detects that the second operation has been performed based on the sensor signal from the sensor 16 using the threshold values T1 and T2. Can do. Alternatively, as in the first operation, the operation desired by the user is set as the second operation, and the mobile phone device 100 performs the second operation using the threshold set based on the operation. It may be detected.

  The end button 132 is detected by the mobile telephone device 100 detecting that the operation to take the attitude for ending the call, which is the above-mentioned second operation, is performed in the state where the operation to the end button 132 is invalidated. By canceling the invalidation of the operation to the user, since the operation on the end button 132 is validated when the user takes a posture to end the call, the convenience of the user is not impaired.

  In addition, cancellation | release of invalidation of operation to the completion | finish button 132 by detection of said 2nd operation | movement is not essential. For example, after invalidating the operation on the end button 132, the mobile phone device 100 may release the invalidation when a predetermined period has elapsed. Also by doing this, it is possible to prevent the erroneous operation when the mobile phone device 100 is put on the ear as described above.

  Furthermore, the mobile telephone device 100 may release the invalidation by accepting a predetermined operation. By doing in this way, a user's convenience can be ensured more.

<Functional configuration>
FIG. 6 is a block diagram showing an example of a functional configuration of the mobile telephone device 100 for performing the above operation. Each function of FIG. 6 is mainly realized by the CPU 10 when the CPU 10 of the mobile phone device 100 reads the program stored in the ROM 11 onto the RAM 12 and executes it. However, at least a part of the functions may be realized by other hardware shown in FIG. 2 or other hardware such as an electric circuit (not shown).

  Referring to FIG. 6, CPU 10 of portable telephone apparatus 100 includes an operation input unit 101 and a signal input unit 102. The operation input unit 101 receives a user operation input by receiving an input of an operation signal from the touch panel 13. The signal input unit 102 receives an input of a sensor signal from the sensor 16 which is a gyro sensor.

  CPU 10 further includes a call detection unit 103, a control unit 104, a call execution unit 105, and a notification unit 106.

  The call detection unit 103 is notified from the operation input unit 101 that the start button 131 has been operated, and then starts a call to the mobile phone device 100 based on the sensor signal received by the signal input unit 102. It is detected that the mobile phone device 100 has transitioned to a call state by detecting that an action for taking a posture for the mobile phone has been performed. Specifically, the call detection unit 103 stores the threshold values T1 and T2 in advance, and the sensor signal from the sensor 16 as a gyro sensor simultaneously exceeds the threshold value T1 or the threshold value T2 in each direction. When it is detected that the mobile phone device 100 has been operated, the mobile phone device 100 is determined to have taken an attitude for starting a call.

  When the call detection unit 103 detects that the call state has shifted to the call state, the control unit 104 invalidates the operation on the end button 132 in the call state. The invalidation of the operation to the end button 132 may be realized, for example, by not displaying the end button 132 on the touch panel 13, or when the operation input unit 101 receives an operation signal indicating a touch on the end button 132. The operation defined in advance with respect to the operation signal may be realized by the CPU 10 not performing it, or by the operation input unit 101 not receiving an input of the operation signal indicating a touch on the end button 132. Also good.

  The call execution unit 105 controls the communication unit 17 to start a call when notified by the operation input unit 101 that the operation on the start button 131 has been performed.

  When the notification unit 106 displays the call screen as shown in FIG. 3B on the touch panel 13 during a call, when the operation on the end button 132 is invalidated by the control unit 104, The invalidation is notified on the call screen.

  Preferably, CPU 10 further includes a setting unit 107. The setting unit 107 sets the threshold values T and T2. That is, the setting unit 107 sets an operation of taking a posture for starting a call.

<Operation flow>
FIG. 7 is a flowchart showing the flow of the operation of the mobile phone device 100. The operation shown in the flowchart of FIG. 7 is realized by the CPU 10 of the mobile phone device 100 reading out the program stored in the ROM 11 onto the RAM 12 and executing the program to exhibit the functions of FIG. The operation illustrated in the flowchart of FIG. 7 is started when a call arrives at the mobile telephone device 100.

  Referring to FIG. 7, when it is detected that start button 131 is touched (YES in step S101), CPU 10 starts control of a call (step S103). If start button 131 is not touched for a predetermined period of time from an incoming call (NO in step S101), CPU 10 is a so-called missed call, which is defined in advance for terminating an incoming call without starting a call. The processed process is executed (step S105).

  After the call is started in step S103, when an operation for taking a posture for call start, which is the first operation, is detected (YES in step S107), CPU 10 invalidates the operation on end button 132 (lock (Step S109). Preferably, the CPU 10 notifies the user by displaying on the call screen that the operation on the end button 132 is invalidated (step S111).

  Preferably, in a state where the operation on end button 132 is invalidated, when an operation for taking a posture for call termination which is the second operation is detected (YES in step S113), CPU 10 selects end button 132. The invalidation of the operation is canceled (step S115). When the user is notified of the invalidation of the operation on the end button 132 in step S111, the CPU 10 ends the notification (step S117).

  Thereafter, when it is detected that the end button 132 is touched (YES in step S119), the CPU 10 ends the control of the call (step S121). Then, the CPU 10 ends a series of operations.

  When the operation to take the attitude for call start which is the first operation is not detected after the start button 131 is touched (NO in step S107), the CPU 10 performs the operation in the steps S109 to S117, that is, The operation for disabling the operation on the end button 132 may be skipped. In this case, the call on the mobile phone device 100 is started, but the operation on the end button 132 is not invalidated. However, when the first operation is not detected after the start button 131 is touched, for example, the touch panel 13 or a remote controller (not shown) with the cellular phone device 100 placed in a pocket, bag or desk This is a case where the start button 131 is operated and the call is started without touching the ear. Specifically, when the user connects an earphone to the mobile phone device 100 and makes a call using the earphone, or when the output volume of the speaker 15 is increased and the call is not made to the ear, or the like. In such a case, since the possibility of an erroneous operation on the end button 132 is low, even if the CPU 10 skips the operation of invalidating the operation on the end button 132, the erroneous operation can be suppressed.

<Effect of the embodiment>
By performing the above-described operation in mobile telephone apparatus 100 according to the present embodiment, erroneous operation during a call can be effectively performed without the user performing special settings and operations, and without impairing the convenience of the user. Can be prevented.

Second Embodiment
The mobile telephone device 100 uses the sensor 16 different from the gyro sensor, an operation of taking a posture for call start which is the first operation and an operation of taking a posture for call termination which is the second operation. May be detected. The mobile phone device 100 according to the second embodiment includes an acceleration sensor as the sensor 16. The appearance, the other hardware, and the functional configuration of the mobile phone device 100 according to the second embodiment are the same as those of the mobile phone device 100 according to the first embodiment, and therefore the description will not be repeated.

  FIG. 8 shows x, y, x, y, and x by the sensor 16, which is an acceleration sensor mounted on the mobile telephone device 100, when the mobile telephone device 100 in a posture used in front view is lifted while being twisted by 90 °. It is a figure showing the time passage of the output of each z direction. Referring to FIG. 8, the output of sensor 16 shows a significant change in time P ′ in the x, y, and z directions, respectively. The detection result of FIG. 8 represents that a rapid speed change in each direction has occurred with respect to the mobile phone device 100 at time P ′. In other words, the detection result in FIG. 8 indicates that at time P ′, an operation of causing the lifted portable telephone device 100 to approach the ear is added, that is, the user of the portable telephone device 100 has an attitude for call initiation. Indicates that an action has been taken.

  Therefore, the threshold value of the slope of the output value in each direction is set in advance, and the change of the output value exceeding the threshold value is detected, so that the mobile telephone device 100 causes the user to have an attitude for the call start. It is possible to detect that the operation of taking The threshold may also be determined experimentally and stored in advance in the mobile phone device 100. Alternatively, the user of the mobile telephone device 100 operates to take a posture for speech start using the actual mobile telephone device 100, and the mobile telephone device 100 generates a threshold based on the output of the sensor 16 obtained from the operation. May be set and stored.

  As shown in FIG. 8, the mobile telephone device 100 according to the second embodiment performs the same operation as that of the mobile telephone device 100 according to the first embodiment to obtain the sensor 16 as an acceleration sensor. The operation on the end button 132 can be appropriately invalidated by using. That is, by performing the above operation also in the mobile telephone device 100 according to the second embodiment, the user does not make special settings or operations, and the convenience of the user is not impaired. Incorrect operation can be effectively prevented.

Third Embodiment
The sensor 16 may not be only one type of sensor as shown in the first embodiment and the second embodiment. That is, the sensor 16 may be a combination of multiple types of sensors. For example, the mobile phone device 100 takes an attitude for starting a call, which is a first operation, using both a gyro sensor and an acceleration sensor, and takes an attitude for ending a call, which is the second operation. Motion may be detected. In this case, the mobile phone device 100 that detects the above operation using a plurality of types of sensors as the mobile phone device 100 according to the third embodiment stores a threshold value for each sensor. Then, in the mobile phone device 100 according to the third embodiment, the above operation is performed when the value obtained from the output value or the output value of all the sensors (for example, the change amount of the output value) exceeds the threshold value. It may be detected that it has been done. Alternatively, in the mobile telephone device 100 according to the third embodiment, the value (for example, the amount of change of the output value) obtained from the output value or the output value of at least one of the plurality of types of sensors is a threshold. If the value is exceeded, it may be detected that the above operation has been performed.

  With such a configuration as well, in the mobile telephone device 100 according to the third embodiment, the user does not make any special settings or operations, nor does the user's convenience deteriorate. Can be effectively prevented.
