(Embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 and 2 are external views showing an example of a terminal device 100 according to an embodiment of the present invention.
A terminal device 100 shown in FIGS. 1 and 2 is a terminal device having a configuration in which a mobile phone and an information processing terminal are combined, which is called a smartphone (high-function mobile phone terminal device). FIG. 1 is a front view of the main body of the terminal device 100 as viewed from the front. FIG. 2 is a right side view of the main body of the terminal device 100 as viewed from the right side.

As shown in FIGS. 1 and 2, a display unit 120 and a touch panel 108 are provided on the front surface of the terminal device 100.
The touch panel 108 is a member having a function for inputting information from the user.
In the present embodiment, the method adopted for the touch panel 108 may respond to the contact of a part of the user's body (operation body), for example, a finger, ear, face, etc. Alternatively, a known type touch panel such as a resistive film type may be used.

An audio output unit 104 and a press sensor unit 107 are provided on the upper part of the touch panel 108.
The voice output unit 104 is a member that outputs voice such as received voice and notification sound. For example, a speaker is used as the audio output unit 104, but a known audio output device can be used in the present embodiment, and is not limited to a specific audio output device.

  The press sensor unit 107 is a member that detects a force (hereinafter, referred to as “pressing force”) generated when the touch panel 108 is pressed and outputs a press detection value corresponding to the magnitude of the detected pressing force.

  As shown in FIGS. 1 and 2, the press sensor unit 107 is provided in the vicinity of the audio output unit 104, for example. That is, when making a call, the user presses the touch panel 108 with the ear or face in contact with the touch panel 108 in order to hear the received voice output from the voice output unit 104. The press sensor unit 107 detects a pressing force generated when the user touches the touch panel 108 with his / her ear or face and presses the touch panel 108, and outputs a pressing detection value of the pressing force.

  The press sensor unit 107 is preferably provided in the vicinity of the audio output unit 104, but in the present embodiment, the position of the press sensor unit 107 is not limited as long as it is on the terminal device 100. Here, the vicinity is, for example, a range corresponding to the size of a human ear. Specifically, the vicinity may be a range corresponding to the average value of the size of the human ear, or a range corresponding to the maximum value or the minimum value of the size of the human ear. Moreover, since the size of a person's ear differs for each country, each region, and each user's age, the neighborhood may be set for each country, each region, and each user's age.

  A voice input unit 105 is provided below the touch panel 108. The voice input unit 105 is a member for inputting voice (transmission voice). For the voice input unit 105, for example, a microphone is used. Although a microphone is used in the present embodiment, a known voice input device can be used and is not limited to a specific voice input device.

  The display unit 120 is a member having a function for presenting information to the user. The display unit 120 includes a display device such as a liquid crystal device or an organic EL device, for example.

FIG. 3 is a schematic block diagram illustrating an example of the configuration of the terminal device 100 according to the present embodiment.
The terminal device 100 includes a transmission / reception antenna 101, a communication unit 102, an output audio processing unit 103, an audio output unit 104, an audio input unit 105, an input audio processing unit 106, a press sensor unit 107, and a touch panel 108. And a control unit C1. In addition, the terminal device 100 includes a general known function of a smartphone.

  The communication unit 102 performs various processes of mobile phone communication such as outgoing call, incoming call, voice signal transmission, voice signal reception, and transmission / reception processing via the transmission / reception antenna 101. The communication unit 102 generates an encoded audio signal by demodulating the received signal that has been subjected to various types of processing. The communication unit 102 outputs the generated encoded audio signal to the output audio processing unit 103. The communication unit 102 modulates the encoded audio signal input from the input audio processing unit 106 to generate a transmission signal. The communication unit 102 transmits the generated transmission signal to, for example, a base station apparatus (not shown) of the mobile phone communication system via the transmission / reception antenna 101.

  The output audio processing unit 103 generates an audio signal by decoding the encoded audio signal input from the communication unit 102. The output audio processing unit 103 outputs the generated audio signal to the audio output unit 104.

  The audio output unit 104 converts the audio signal input from the output audio processing unit 103 into audio. When the audio signal indicating cancellation of the mute mode (resumption of call interruption) is input from the mute release notification unit C11 of the control unit C1, the audio output unit 104 notifies the user with, for example, a notification sound.

  In the present embodiment, the audio output unit 104 is notified by a notification sound as a method of notifying the user of the cancellation of the mute mode. However, the audio output unit 104 is notified by vibration using a vibration unit (not shown). Or they may be combined and notified. Since the cancellation of the mute mode is notified by at least one of sound and vibration, the user can know the cancellation of the mute mode, for example, with the terminal device 100 placed on the ear (attitude to talk). Further, in the function block (not shown) having the voice output unit 104 or other functions, other methods, for example, a display unit (not shown) is provided, and the user can cancel the mute mode by using an icon or the like. May be notified to the user.

  The voice input unit 105 converts voice input by the user into a voice signal. The voice input unit 105 outputs the converted voice signal to the input voice processing unit 106.

  The input voice processing unit 106 controls a function for interrupting a call and a function for resuming the interrupted call. Specifically, when the user sets the mute mode (call interruption), the mute setting unit C10 included in the control unit C1 causes the input audio processing unit 106 to interrupt the output of the audio signal (call). In addition, when the mute mode is canceled (resumption of call) in the mute setting unit C10, the input voice processing unit 106 resumes the call. When an audio signal is input from the audio input unit 105, the input audio processing unit 106 generates an encoded audio signal by encoding the audio signal. The input speech processing unit 106 outputs the generated encoded speech signal to the communication unit 102.

  The pressure sensor unit 107 detects the magnitude of the pressure applied to the touch panel 108. The pressure sensor unit 107 outputs a pressure detection value corresponding to the detected magnitude of the pressing force to the determination unit C14 included in the control unit C1. For example, the pressing sensor unit 107 is a piezoresistive sensor whose resistance value changes according to the magnitude of the pressing force.

  Thereby, the press sensor part 107 can obtain a press detection value. That is, the pressure sensor unit 107 detects a pressure detection value equal to or greater than a value when a part of the user's body is not in contact with the touch panel 108 (when not in contact). In the present embodiment, a known type of pressure sensor such as a capacitance type may be used for the pressure sensor unit 107.

  The touch panel 108 calculates, as an operation input device, position coordinates of a position where a part of the user's body is in contact. The touch panel 108 outputs the calculated position coordinates to the contact detection unit C12 included in the control unit C1.

  The control unit C1 is realized, for example, by a CPU (Central Processing Unit) (not shown) executing a program. For example, the control unit C1 determines whether or not the pressure detection value is equal to or greater than a threshold value based on the pressure detection value input from the pressure sensor unit 107 and information on the pressure read from the storage unit C13 included in the control unit C1. To do. Here, the information on the pressing force is information on the threshold value of the pressing force, information on the threshold value of the pressing transition time, and information on the threshold value of the pressing duration.

  Based on the position coordinates of the position where a part of the user's body is in contact with the touch panel 108 and the determination result of the pressed detection value, the control unit C1 sends the mute setting unit C10 to the input audio processing unit 106, for example, mute mode. Instruct to cancel. The detailed operation of the control unit C1 will be described later.

  The control unit C1 includes a mute setting unit C10, a mute release notification unit C11, a determination unit C14, a contact detection unit C12, and a storage unit C13. In addition, the control unit C1 includes a known functional member.

  The mute setting unit C10 performs the function of setting the mute mode (call interruption) and canceling the mute mode (resuming the call). When the mute setting unit C10 releases the mute mode, the mute release notification unit C11 generates an audio signal for notifying the user of the release of the mute mode. The mute release notifying unit C11 outputs the generated audio signal to the audio output unit 104. The contact detection unit C12 is an area in which a part of the user's body contacts the touch panel 108 based on the position coordinates of the position where the part of the user's body contacts the touch panel 108 (hereinafter referred to as “contact area”). Is calculated.

  The contact detection unit C12 outputs the calculated contact area to the determination unit C14. The storage unit C13 stores information related to the pressing force and information related to contact. Here, the information related to contact is information related to a threshold of a contact area where a part of the user's body contacts the touch panel 108. The determination unit C14 reads information on the pressing force and information on contact from the storage unit C13.

  The determination unit C14 performs a mute release determination process based on the detected pressure value, the contact area, the information regarding the pressing force, and the information regarding the contact, and outputs the determination result to the mute setting unit C10. A description of specific functional blocks related to the control unit C1 and a description of mute release determination processing will be described later.

  The mute setting unit C10 switches the input audio processing unit 106 from the normal mode in which the call is valid to the mute mode in which the call is interrupted during the call. Specifically, when the mute setting unit C10 is set to the mute mode, the call is interrupted and transmission of the input voice is interrupted. Here, the normal mode is, for example, a mode in which voice is output to the voice output unit 104 and voice is input from the voice input unit 105, that is, a mode in which a call is performed.

  After the call is interrupted, the mute setting unit C10 cancels the mute mode and switches to the normal mode using the determination result of the mute release determination process of the determination unit C14. That is, when the determination unit C14 determines to resume the call, the mute setting unit C10 cancels the mute mode and causes the input voice processing unit 106 to resume the call.

  When the determination unit C14 determines to resume the call, the mute release notification unit C11 notifies the user of the resumption of the call. Specifically, when the determination unit C14 determines to resume the call, the mute setting unit C10 cancels the mute mode. When canceling the mute mode, the mute setting unit C10 causes the mute release notification unit C11 to generate an audio signal for notifying the user of the release of the mute mode. The mute release notifying unit C11 outputs the generated audio signal to the audio output unit 104.

  The contact detection unit C12 includes a contact area S where a part of the user's body is in contact with the touch panel 108, a position coordinate of a position where the part of the user's body is in contact with the touch panel 108, and the position of the user's body in contact with the touch panel 108. Calculate some contact shapes. The contact detection unit C12 detects, from the touch panel 108, position coordinates indicating a position where a part of the user's body is in contact with the touch panel 108.

  At this time, the touch panel 108 changes the number of position coordinates to be simultaneously output according to the contact area S of the region on the touch panel 108 with which a part of the user's body is in contact. The contact detection unit C12 calculates the contact area S based on the number of position coordinates output simultaneously from the touch panel 108, for example. The contact detection unit C12 outputs the calculated contact area S to the determination unit C14.

The contact detection unit C12 detects a contact area S where a part of the user's body contacts the touch panel 108. The contact detection unit C12 is used to increase the determination accuracy that the determination unit C14 determines to resume the call using information related to contact.
The storage unit C13 includes a pressing information storage unit C131 and a contact information storage unit C132.

  The pressing information storage unit C131 stores information regarding the pressing force. The contact information storage unit C132 stores information related to contact. In the present embodiment, it is described that the information regarding the pressing force and the information regarding the contact are stored in advance in the storage unit C13. However, each information may be determined and stored by the user. Alternatively, other conditions such as each region and each age may be provided and stored. In addition, although it is described that information on pressing force and information on contact are stored, at least one of them may be stored. Thereby, the determination unit C14 can increase the determination accuracy for determining to resume the call.

  When the pressure detection value detected by the pressure sensor unit 107 is input, the determination unit C14 reads information related to the pressing force from the storage unit C13. Here, the information on the pressing force is information on the threshold value of the pressure detection value, information on the threshold value of the time during which the pressure detection value continues to exceed the threshold value of the pressure detection value, and the pressure sensor unit 107 starts to detect the pressure detection value. Information about the threshold value of the time from when the detected pressure value reaches the threshold value of the detected pressure value.

In the present embodiment, the information on the pressing force is stored in the storage unit C13 in advance, but may be determined by the user and stored in the storage unit C13.
The determination unit C14 measures a time T ₁ (press transition time) from the time when the pressure detection value is detected until the threshold value of the pressure detection value stored in the storage unit C13 is reached. Determining unit C14 is press detection value from the time the threshold is reached the press detection value, the threshold or more pressure detection value measures the duration T ₂ which continues to be detected _(pressing duration).

The determination unit C14 determines whether or not the pressure detection value is equal to or greater than the threshold value P of the pressure detection value based on the information regarding the pressing force read from the storage unit C13 and the input pressure detection value (first determination). . If the detected pressing force value is equal to or higher than the threshold P of the pressing detection value, the determination unit C14 includes a determination is made as to push the transition time T ₁ (second determination). Determining unit C14, when press detection value input is equal to or more than the threshold value P of the pressure detection value, and the time to reach the threshold P of the pressing detection value is within the threshold for pressing the transition time T _1, It is determined that the call is resumed.

Further, the determination unit C14 continues the pressing for a continuation time during which the pressure detection value equal to or greater than the pressure detection value threshold P is detected from the time when the pressure detection value reaches the pressure detection value threshold P based on the second determination result. determines whether the time T ₂ or more (third determination). On the other hand, the determination unit C14 does not resume the call (cancel the mute mode) when the detected pressure value is less than the threshold value P of the detected pressure value or when the detected pressure value is not detected.

  If the determination unit C14 determines that the call is to be resumed in the first determination, the second determination, and the third determination, the determination unit C14 causes the mute setting unit C10 to resume the call (release the mute mode). . When the contact area S where a part of the user's body is in contact with the touch panel 108 is input from the contact detection unit C12 to the determination unit C14, the determination unit C14 reads out information related to contact stored in the storage unit C13.

  The determination unit C14 determines the contact area S of the part of the user's body based on the read contact information and the contact area S where the part of the user's body contacts the touch panel 108 input from the contact detection unit C12. Is determined to be in contact with a part of the body of a specific user, for example, an ear, when the condition satisfies the condition that the contact area S is equal to or greater than the lower limit Smin of the information threshold related to contact and the upper limit Smax of the threshold value related to contact. The mute setting unit C10 is made to resume the call. On the other hand, when the contact area S where a part of the user's body touches the touch panel 108 does not satisfy the condition of the threshold lower limit Smin or more and the threshold upper limit Smax or less, the call interruption is continued.

  In the present embodiment, the contact detection unit C12 detects the contact area. However, the contact detection unit C12 may detect a contact shape of a part of the user's body that is in contact with the touch panel 108 or the touch panel 108 The position coordinates of the position where a part of the body contacts may be detected as it is. One or more of at least one of the contact area, the contact shape, and the position coordinates may be detected.

  In this case, the information related to contact further includes information related to a shape in which a part of the user's body comes into contact with the touch panel 108, information related to position coordinates of a position where the part of the user's body comes into contact with the touch panel 108, and the like.

  Here, the contact detection unit C12 receives position coordinates indicating a position where a part of the user's body is in contact with the touch panel 108 from the touch panel 108. At this time, the number of position coordinates that are output simultaneously on the touch panel 108 changes according to the contact shape of the part of the user's body in the area where the part of the user's body is in contact with the touch panel 108.

  Therefore, the contact detection unit C12 calculates, for example, a contact shape of a part of the user's body that makes contact based on the number of position coordinates simultaneously output from the touch panel 108, and calculates the calculated contact shape of the part of the user's body. Is output to the determination unit C14.

  In addition, the determination unit C14 determines a part of the user's body based on the read information related to the contact and the position coordinates of the position where the part of the user's body contacts the touch panel 108 input from the contact detection unit C12. Specified when the position coordinates of the position where the touching touches the condition of the information on the touch, for example, the position coordinates of the position where a part of the user's body touches the touch panel 108 satisfies the condition of the position on the touch panel 108 indicated by the information related to the touch It is determined that a part of the user's body, for example, the ear is touching, and the mute setting unit C10 is caused to resume the call. On the other hand, when the position coordinates of the position where a part of the user's body touches the touch panel 108 does not satisfy the condition, the call is interrupted.

  In addition, the determination unit C14 determines a part of the user's body to be contacted based on the read-out information on the contact and a contact shape in which the part of the user's body contacts the touch panel 108 input from the contact detection unit C12. When the contact shape is similar to the shape of the information related to contact, it is determined that a part of a specific user's body, for example, an ear is touching, and the mute setting unit C10 restarts the call. On the other hand, when the contact shape in which a part of the user's body comes into contact with the touch panel 108 is different from the shape of the information related to the contact, the call is interrupted.

  Furthermore, the contact shape in which a part of the user's body is in contact with the touch panel 108 stored in the storage unit C13 may be stored, for example, in the case of an ear, by taking an average value of the size of the human ear, However, the ear shape may be stored in the storage unit C13 in advance. In addition, the maximum or minimum value of the size of the human ear, or both of them may be stored as shapes, and each country, each region, and each user's age. It may be stored for each age.

Figure 4 is a press detection value according to the present embodiment, the pressing transition time T _1, a conceptual diagram showing an example of the relationship between the pressing duration T _2.
4, the horizontal axis represents time, taking the pressure detection value on the vertical axis, against the pressing detection value, and pressing the transition time T _1, is a diagram showing the relationship between the pressing duration T _2. P of the pressure detection value shown in FIG. 4 represents a threshold value. In press detection characteristics G1 as shown in FIG. 4, the pressing detection value has reached the threshold value P of the pressure detected value at time t _1. In the present embodiment, in order to prevent a call from being resumed due to a temporary contact with a part of the user's body on the touch panel 108, a condition for a threshold lower limit T ₁ min and a threshold upper limit T ₁ max for the press transition time T _1. Is provided.

The difference in time between the lower limit T ₁ min of the threshold and the upper limit T ₁ max of the threshold is, for example, about 0.5 seconds. In the pressure detection characteristic G1, time A1 is required until the pressure detection value reaches the threshold value P of the pressure detection value, but the time A1 does not reach the lower limit T ₁ min of the pressure transition time T ₁ . It is assumed that a part of the user's body is temporarily in contact with the touch panel 108 and the call is not resumed.

In press detection characteristic G2 as shown in FIG. 4, the pressing detection value has reached the threshold value P of the pressure detected value at time t _2. In this case, the time from time 0 to time _{t 2, the} time between a lower limit _T 1 min and the upper limit _T 1 max threshold threshold, i.e., in the range of pressing the transition time _{T 1.} That is, the determination unit C14 performs a second determination as to pressing the transition time T _1, determines that the result, performs a resume call. The pressing detection value the time t ₂ after having reached the threshold value P of the pressure detection value, until time t _5, the pressing detection value equal to or more than the threshold value P of the pressure detection value is continuously detected in the pressing detection characteristics G2 shown Has been.

As a result, the time A3 from the time _{t 2} to time _{t 5} becomes the pressing duration _{T 2.} That is, the determination unit C14 performs the third determination for the time A3, and as a result, determines to resume the call. Accordingly, the determination unit C14 includes a first and a determination based on the press detection value, the second and the determination based on a press transition time T _1, the third determination and based on a press duration T _2, the call resumption conditions The call is resumed.

In press detection characteristic G3 as shown in FIG. 4, the pressing detection value at time t ₃ has reached the threshold value P of the pressure detection value. In this case, the time from time 0 to time _{t 3,} the time between a lower limit _T 1 min and the upper limit _T 1 max threshold threshold, i.e., in the range of pressing the transition time _{T 1.} Accordingly, the determination unit C14 performs a second determination as to pressing the transition time T _1, is determined to perform the resumption of the call. However, the pressing detection value, the time t ₃ after having reached the threshold value P of the pressure detection value is below the threshold value P of the pressure detected value at time t _4.

In press detection characteristic G3, time A2 between the time t ₃ to time t ₄ does not satisfy the conditions of the pressing duration T _2. That is, the determination unit C14 performs the third determination with respect to the pressing duration T _2, determines that the result, and continues interruption of the call. Accordingly, the determination unit C14, in the second determination based on a press transition time T _1, and determines to perform the resume call, in the third determination based on a press duration T _2, and continues interruption of the call determined To do. That is, the call is not resumed.

In the present embodiment, the time and press detection value of the pressure detection characteristic shown in FIG. 4, the time to press detection value reaches the threshold value P of the pressure detection value, pressing the transition time T ₁ and its condition, the pressing duration T ₂ and its conditions are shown, and the present invention is not limited to this relationship. In the present embodiment, the pressing transition time T ₁ has a condition of a time T ₁ between the lower limit T ₁ min of the threshold and the upper limit T ₁ max of the threshold, but only the condition of the lower limit T ₁ min of the threshold is set. It may be determined using.

FIG. 5 is a flowchart illustrating an example of the operation of the determination unit C14 according to the present embodiment.
The user sets the mute mode (call interruption) during a call as necessary (S101).
When the mute mode is not set (S101-NO), the mute setting unit C10 does not cause the determination unit C14 to perform the operations after S102.
When the user sets the mute mode (S101-YES), the pressure sensor unit 107 detects a pressure detection value (S102).

  The determination unit C14 determines whether or not the pressure detection value detected by the pressure sensor unit 107 is a non-contact value, for example, 0 or more (S103). When the pressure detection value is less than the non-contact value (S102—NO), the pressure sensor unit 107 detects the pressure detection value (S102). On the other hand, when the detected pressure value is greater than or equal to the non-contact value, the determination unit C14 determines whether or not the detected pressure value is equal to or greater than the threshold value P of the detected pressure value (S104).

When the pressure detection value is less than the threshold value P of the pressure detection value (S104-NO), the determination unit C14 determines whether or not the pressure detection value is less than the non-contact value (S105). When the pressure detection value is less than the non-contact value (S105-YES), the determination unit C14 causes the pressure sensor unit 107 to detect the pressure detection value again (S102). On the other hand, if the pressing detection value is greater than or equal to the value at the time of non-contact (S105-NO), the determination unit C14 is to measure the pressing transition time _{T 1} (S106). The determination unit C14 determines whether or not the pressure detection value is equal to or greater than the threshold value P of the pressure detection value (S104).

  When the pressure detection value is equal to or greater than the threshold value P of the pressure detection value (S104-YES), the determination unit C14 causes the contact detection unit C12 to calculate the contact area S where a part of the user's body contacts the touch panel 108. The determination unit C14 determines whether or not the contact area S calculated by the contact detection unit C12 is within the range between the lower limit Smin and the upper limit Smax (S107).

When the contact area S calculated by the contact detection unit C12 is outside the range between the lower limit Smin and the upper limit Smax (S107—NO), the determination unit C14 causes the press sensor unit 107 to detect the detected pressure value ( S102).
On the other hand, the contact area S which is calculated on the contact detection unit C12 is when (107-YES) is within the range between the lower limit Smin and the upper limit Smax, determination unit C14 includes pressing the transition time _{T 1} is lower _T 1 min and the upper limit T _It is determined whether it is within the range of ₁ max (S108).

When pressing the transition time _{T 1} is not within the range between the lower limit _T 1 min and the upper limit _{T 1 max (S108-NO)} , the determination unit C14 resets the timer pressing the transition time _{T 1} (S109).
On the other hand, if the pressing transition time _{T 1} is in the range of a lower limit _T 1 min and the upper limit _{T 1 max (S108-YES)} , the determination unit C14 starts measurement of pressed time duration _{T 2} (S110).
The determination unit C14 determines whether or not the pressure detection value maintains a threshold value P or more of the pressure detection value (S111).

When the pressure detection value does not maintain the pressure detection value threshold P or more (S111-NO), the determination unit C14 causes the pressure sensor unit 107 to detect the pressure detection value (S102). On the other hand, when the pressing detection value is maintained above the threshold P of the pressing detection value (S111-YES), the determination unit C14 determines whether the measurement value of the pressing duration _{T 2} is equal to or larger than the threshold (S113) .

If the measured value of the pressing duration _{T 2} is less than the threshold value (S113-NO), the determination unit C14 resets the timer pressing duration _{T 2} (S112), starts measuring the pressing duration _{T 2} again (S110).
On the other hand, when the measured value of the pressing duration _{T 2} is equal to or greater than the threshold (S113-YES), the determination unit C14 is mute setting unit C10, causes the release of the Mute mode (S114).

  The determination unit C14 causes the mute release notification unit C11 to generate an audio signal for notifying the user of the release of the mute mode. The determination unit C14 causes the mute release notification unit C11 to output the generated audio signal to the audio output unit 104 and notifies the user of the release of the mute mode (S115).

  In the present embodiment, the call is resumed for the mute mode, but the call may be resumed by switching from the hold (call interruption) to the normal mode. In this case, it can be executed in the same procedure as the resumption of the call from the mute mode. In addition, switching from the standby mode (during a non-call) to a call mode (call start), that is, switching to a call can be performed in the same procedure.

  Furthermore, in the present embodiment, the call is resumed using the pressure sensor unit 107 and the contact detection unit C12. However, the user may resume the call by inputting voice to the voice input unit 105. The voice may be resumed by combining any of the voice, the pressure sensor unit 107, and the contact detection unit C12. In this case, the mute setting unit C10 detects the audio signal for the audio input from the audio input unit 105, and cancels the mute mode.

  Thus, in this embodiment, the voice input unit 105 receives a voice. The audio processing unit (output audio processing unit 103, input audio processing unit 106) processes an audio signal based on the input audio. The communication unit 102 transmits and receives audio signals processed by the audio processing unit (the output audio processing unit 103 and the input audio processing unit 106). The pressing sensor unit 107 detects the magnitude of the pressing force. Based on the pressing force detected by the pressing sensor unit 107, the control unit C1 controls a call function by switching a plurality of modes in which the voice communication state of the voice signal is different.

  In the conventional mode switching using the proximity detection unit, when the user does not intend to switch between the normal mode and the mute mode, the thing may switch from the mute mode to the normal mode due to the proximity of the proximity detection unit. there were. For this reason, the function of the telephone call cannot be controlled appropriately. However, by using the press sensor unit 107, the mode that is not intended by the user due to the proximity of an object is not switched, and the call can be controlled appropriately.

  The control unit C1 controls a function for starting or resuming a call. The storage unit C13 stores information related to the pressing force. The determination unit C14 reads information related to the pressing force stored in the storage unit C13. The determination unit C14 determines whether or not to start the call of the own device or to resume the call based on the read information regarding the pressing force and the pressing force detected by the pressing sensor unit 107. As a result, it is possible to increase the determination accuracy with which the determination unit C14 determines that the call is to be resumed using the information related to the pressing force, and the call can be appropriately controlled.

  The information regarding the pressing force includes information regarding the threshold of pressing force, information regarding the threshold of the pressing transition time during which the pressing force continues to exceed the pressing force threshold, and the time at which the pressing sensor unit 107 starts detecting the pressing force. It is the information regarding the threshold value of the duration until the pressure reaches the threshold value of the pressing force. As a result, the convenience of the user during a call can be improved, the cancellation of the mute mode due to an erroneous operation can be prevented, and the call can be controlled appropriately.

  The touch panel 108 detects the position coordinates of the position where the operating body contacts. The contact detection unit C12 detects a contact area where the operating body touches the touch panel 108 or a contact shape of the operating body touching the touch panel 108. As a result, the determination unit C14 can increase the determination accuracy for determining that the call is to be resumed using the information related to the contact detected by the contact detection unit C12. In addition, it is possible to prevent the mute mode from being canceled due to an erroneous operation, and it is possible to improve user convenience during a call. Furthermore, it is possible to appropriately control the call.

  The terminal device 100 further includes a sound output unit 104 that outputs sound based on a sound signal received from another terminal device. The press sensor unit 107 is located in the vicinity of the audio output unit 104. Thereby, the detection accuracy of the pressure detection value of the pressure sensor unit 107 can be increased, and the start of a call or the resumption of a call when the user does not intend can be prevented. Furthermore, it is possible to appropriately control the call.

  When the determination unit C14 determines to resume the call, the notification unit (mute release notification unit C11) notifies the user of the resumption of the call. This eliminates the need for the user to resume the call by manual operation, and allows the user to resume the call in a posture in which the call is made, for example, with the terminal device 100 placed on the ear. Further, the user can know that the call has been resumed from the attitude of making a call.
