  The cellular phone 1 according to the present embodiment includes an application for detecting the occurrence of an accident to the user of the cellular phone 1 or the surroundings of the user and promptly notifying the occurrence of the accident. The control unit 11 executes a control process related to the application of this function (hereinafter referred to as “accident notification control process”). As illustrated in FIG. 2, the control unit 11 includes an accident notification control unit 31 for executing an accident notification control process. The accident notification control unit 31 is realized as a function of a program executed by the control unit 11.

  In the accident notification control process, the accident notification control unit 31 compares the dynamic acceleration detected by the acceleration detection unit 22 with the reference acceleration information in the accident reference information table 12a. In addition, the accident notification control unit 31 compares the sound detected by the voice input unit 15 with the reference sound information in the accident reference information table 12a in the accident notification control process. Based on the comparison result between the detected dynamic acceleration and the reference acceleration information and / or the comparison result between the detected sound and the reference sound information, the presence / absence of an accident is detected. When the occurrence of the accident is detected, the accident notification control unit 31 executes a control process for notifying the occurrence of the accident to the contact indicated by the contact information held in the emergency contact table 12b.

  Hereinafter, a specific example of the accident notification control process will be described.

<Example 1>
As an example of the accident, a case where the user of the mobile phone 1 falls due to a sudden illness or the like can be cited. When the user of the mobile phone 1 falls due to a sudden illness or the like, the accident notification control unit 31 according to the first embodiment detects the user's fall and transmits an e-mail to the emergency contact.

  FIG. 4A is a conceptual diagram illustrating an example assuming transition of the dynamic acceleration Gr generated in the mobile phone 1 when the user falls due to a sudden illness or the like. In FIG. 4A, the horizontal axis represents elapsed time (milliseconds), and the vertical axis represents dynamic acceleration (G).

  Referring to FIG. 4A, until the elapsed time t1, the dynamic acceleration Gr generated in the mobile phone 1 changes with a very small value. At the elapsed time t1, the user wearing the mobile phone 1 falls. Then, the mobile phone 1 moves violently due to a large impact caused by the fall, and the dynamic acceleration Gr generated in the mobile phone 1 increases rapidly. After that, the dynamic acceleration Gr applied to the mobile phone 1 reaches a maximum at the elapsed time t2, and then rapidly decreases and transitions at a very small value similar to that before the increase.

As described above, generally, when a user who wears the mobile phone 1 falls, the mobile phone 1 generates a dynamic acceleration that is extremely larger than the dynamic acceleration that occurs during normal use. Note that “normal use” of the mobile phone 1 is a general use of the mobile phone 1 such as when a user makes a call, creates an e-mail, or the like in situations that may occur on a daily basis, such as walking or riding. To perform an operation that can be assumed when using the function. “Normal use” includes the case where the user stores the mobile phone 1 in a pocket or bag without operating the mobile phone 1 in a situation that may occur on a daily basis.

  Therefore, in the first embodiment, as shown in FIG. 4A, a predetermined value that does not exceed the case of the dynamic acceleration that can occur during normal use and that exceeds the case of the dynamic acceleration that can occur when the user falls. The acceleration threshold value Gsh1 is set. The accident notification control unit 31 monitors the value of the dynamic acceleration (detection signal corresponding to the dynamic acceleration) output from the acceleration detection unit 22, and is not assumed when the mobile phone 1 is normally used, and is a predetermined acceleration threshold value Gsh1. When the above large dynamic acceleration occurs in the mobile phone 1, it is considered that the user of the mobile phone 1 has fallen, and an e-mail is transmitted to the emergency contact.

  For example, if the dynamic acceleration generated in the mobile phone 1 during normal use is about 0 to 0.03 G, and the dynamic acceleration generated in the mobile phone 1 when the user falls is about 0.15 G, the acceleration threshold Gsh1 is Set to 0.12G. Thus, by setting the acceleration threshold value Gsh1, it is possible to detect a user's fall.

  FIG. 4B is an example of the accident reference information table 12a according to the first embodiment. FIG. 4C is an example of the emergency contact address table 12b according to the first embodiment.

  As shown in FIG. 4B, the acceleration threshold value Gsh1 is stored in advance in the accident reference information table 12a. Further, as shown in FIG. 4C, the emergency contact table 12b stores contact information A1 of a partner who immediately reports that the user has fallen and a notification message which reports that the user has fallen. . The contact information A1 is an e-mail address of a hospital or relative, for example. The notification message is, for example, character string information for informing the emergency contact of the user's fall. The notification message is not limited to the example shown in FIG. 4C, but may also include the time when the user's fall was detected, the current position information P1, the detected dynamic acceleration Gr, that is, the magnitude of the impact force, and the like. good.

  FIG. 5A is a flowchart illustrating the accident notification control process according to the first embodiment.

  The control process in FIG. 5A is started by starting the mobile phone 1. This control processing is executed in parallel with other control processing such as control processing of each application.

  Referring to FIG. 5A, the accident notification control unit 31 compares the acceleration threshold value Gsh1 with the detection signal (dynamic acceleration) from the acceleration detection unit 22, and the mobile phone 1 has a dynamic acceleration equal to or higher than the acceleration threshold value Gsh1. It is determined whether or not Gr has occurred (S101).

  When the mobile phone 1 has no dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh1 (S101: NO), the accident notification control unit 31 determines whether or not the mobile phone 1 has generated a dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh1. Repeat the process.

  When dynamic acceleration Gr equal to or greater than the acceleration threshold Gsh1 occurs in the mobile phone 1 (S101: YES), the accident notification control unit 31 reads out the contact information A1 and the notification message stored in the emergency contact table 12b in advance (S102). , S103). The accident notification control unit 31 displays a mail transmission confirmation screen S1 on the display 3 based on the read information (S104).

  FIG. 5B is a diagram showing a display example of the mail transmission confirmation screen S1.

  The mail transmission confirmation screen S1 includes a pop-up window area PW1 superimposed on the window area RW. The pop-up window area PW1 includes a message for detecting whether the user has fallen, but confirming to the user whether or not to send a notification message to the contact information A1 by e-mail, and a CANCEL icon 201.

  By viewing the mail transmission confirmation screen S1, the user can recognize that the mobile phone 1 is about to send a notification message to the emergency contact because the user's fall has been detected.

  Returning to FIG. 5A, the accident notification control unit 31 determines whether or not a tap operation has been performed on the CANCEL icon 201 (S105). When the tap operation is not performed on the CANCEL icon 201 (S105: NO), the accident notification control unit 31 determines whether or not a predetermined time Tsh1 has elapsed since the mail transmission confirmation screen S1 was displayed ( S106). The time Tsh1 is set to a time during which it can be determined whether or not there is a problem with the user's own health after the user falls.

  If the time Tsh1 has not elapsed since the mail transmission confirmation screen S1 was displayed (S106: NO), the accident notification control unit 31 returns the process to S105, and taps the CANCEL icon 201 until the time Tsh1 has elapsed. Repeat the situation determination process. When the CANCEL icon 201 is tapped after the e-mail transmission confirmation screen S1 is displayed until the time Tsh1 elapses (S105: YES), the accident notification control unit 31 sends an e-mail to the emergency contact. Without transmitting, the process returns to S101 to determine again whether the user has fallen.

  If the tap operation is not performed on the CANCEL icon 201 (S105: NO) and the time Tsh1 has elapsed since the mail transmission confirmation screen S1 is displayed (S106: YES), the accident notification control unit 31 displays the emergency contact table. An e-mail containing a notification message informing that the user of the mobile phone 1 has fallen down is sent to the contact information A1 read from 12b (S107).

  Thus, when the user's fall is detected and an e-mail is transmitted to the contact information A1 stored in the emergency contact table 12b, the accident notification control unit 31 ends the accident notification control process. If the mobile phone 1 is not shut down, the accident notification control process is executed again to determine whether the user has fallen.

  As described above, according to the first embodiment, based on the detection signal (dynamic acceleration) from the acceleration detection unit 22, it is determined whether the user, who is one of the accidents, has fallen. When a user's fall is detected, a notification message is created to inform the user that a fall due to a sudden illness or the like has been detected. Therefore, when the user falls due to a sudden illness or the like, the user can send the notification message to the emergency contact by e-mail without creating a notification message by himself / herself to inform the emergency contact such as relatives of the fall.

  Further, according to the first embodiment, after the e-mail transmission confirmation screen S1 is displayed, an e-mail is automatically transmitted if there is no tap operation on the CANCEL icon 201 even after the time Tsh1 has elapsed. Therefore, even if the user loses consciousness when he / she falls, the occurrence of an accident (falling) to the user can be notified to an emergency contact such as a relative.

Further, according to the first embodiment, the mail transmission confirmation screen S1 is displayed before the e-mail is transmitted, and the tap operation status for the CANCEL icon 201 from the user is determined. Therefore, after the fall, if there is no problem with his / her health condition and there is no need to send a notification message to the emergency contact, the user cancels the transmission of the notification message by performing a tap operation on the CANCEL icon 201. can do. In addition, when a strong impact is applied to the mobile phone 1 due to a cause other than a fall, the user performs a tap operation on the CANCEL icon 201 so that an erroneous notification message is transmitted to the emergency contact. Can be prevented.

  In the mobile phone 1, the control process for changing the display direction of the screen displayed on the display 3 based on the detection signal corresponding to the orientation of the mobile phone 1 from the acceleration detection unit 22 including the acceleration sensor is performed by the control unit. 11 is executed. In the first embodiment, the presence / absence of a user's fall (accident) is detected using an acceleration sensor that is also used for changing the display direction of the screen, that is, for other functions. Therefore, the presence or absence of an accident can be detected with a simple configuration without mounting a special sensor on the mobile phone 1.

  In the first embodiment, when a dynamic acceleration equal to or greater than the predetermined acceleration threshold Gsh1 occurs in the mobile phone 1, it is considered that the user of the mobile phone 1 has fallen, and an e-mail is transmitted to the emergency contact. Similar control processing may be executed when another accident occurs. For example, when a traffic accident occurs on the user himself / herself, for example, when the user wearing the mobile phone 1 collides with a car, the mobile phone 1 cannot be assumed during normal use in the same manner as when the user falls. An impact is applied to the mobile phone 1. Accordingly, the dynamic acceleration generated when an impact force that can be determined as a traffic accident is applied is set as the acceleration threshold Gsh1, and the detection signal (dynamic acceleration) from the acceleration detection unit 22 is compared with the acceleration threshold Gsh1, thereby causing an accident. The notification control unit 31 can detect a traffic accident for the user himself / herself. In this case, the mail transmission confirmation screen S1 includes a message for detecting whether or not a traffic accident has been detected for the user, but confirming to the user whether or not to send a notification message to the emergency contact address by e-mail. Thereby, the user can quickly notify the emergency contact of a traffic accident for the user himself / herself.

<Example 2>
As an example of the accident, a person other than the user of the mobile phone 1, that is, a case where a traffic accident of a third party occurs can be cited. The accident notification control unit 31 according to the second embodiment detects that a traffic accident has occurred in a third party around the user of the mobile phone 1 and sends a call to the emergency contact.

  FIG. 6A is a conceptual diagram illustrating an example assuming transition of sound D input by the mobile phone 1 when a third-party traffic accident occurs. In FIG. 6A, the horizontal axis represents elapsed time (milliseconds), and the vertical axis represents sound volume (dB).

  With reference to Fig.6 (a), until the elapsed time t3, the sound D which the mobile telephone 1 inputs changes with a slightly small value. At an elapsed time t3, a third party traffic accident occurs around the user wearing the mobile phone 1. Then, the user or a third party screams, and the sound D input by the mobile phone 1 increases rapidly. The sound D input by the mobile phone 1 may increase due to the sound of a horn immediately before a car or the like collides with a third party, the sound of a sudden brake, or the sound when a car or the like collides with a third party. Thereafter, the sound D input by the mobile phone 1 reaches a maximum at the elapsed time t4, then decreases rapidly, and changes at a slightly larger value than before the increase.

  Thus, generally, when a traffic accident of a third party occurs, the mobile phone 1 generates a sound that is extremely louder than the sound input by the mobile phone 1 during normal use.

Therefore, in the second embodiment, as shown in FIG. 6 (a), it is not exceeded in the case of sound that can be generated during normal use, but is exceeded in the case of sound that can be generated during a traffic accident of a third party. A predetermined sound threshold Dsh1 is set. The accident notification control unit 31 monitors the magnitude of the sound (detection signal corresponding to the sound) output from the voice input unit 15 and is greater than or equal to a predetermined sound threshold Dsh1 that cannot be assumed during normal use of the mobile phone 1. When the mobile phone 1 inputs a loud sound, it is considered that a traffic accident of a third party has occurred, and a call is made to the emergency contact.

  For example, if the sound input by the mobile phone 1 during normal use is approximately 20 to 60 dB, and the sound input by the mobile phone 1 when a person screams is approximately 110 dB or more, the sound threshold Dsh1 Is set to 100 dB. Thus, a third party traffic accident can be detected by setting the sound threshold Dsh1.

  FIG. 6B is an example of the accident reference information table 12a according to the second embodiment. FIG. 6C is an example of the emergency contact address table 12b according to the second embodiment.

  As shown in FIG. 6B, the sound threshold Dsh1 is stored in advance in the accident reference information table 12a. Further, as shown in FIG. 6C, the emergency contact table 12b stores partner information A2 of the partner who immediately reports that a third party traffic accident has occurred. The contact information A2 is, for example, a telephone number such as the police.

  FIG. 7A is a flowchart illustrating the accident notification control process according to the second embodiment.

  The control process in FIG. 7A is started by starting the mobile phone 1. This control processing is executed in parallel with other control processing such as control processing of each application.

  Referring to FIG. 7A, the accident notification control unit 31 compares the sound threshold Dsh1 with the sound input signal (sound) from the sound input unit 15, and has input a sound D that is equal to or higher than the sound threshold Dsh1. It is determined whether or not (S201).

  When the sound D that is equal to or higher than the sound threshold Dsh1 is not input (S201: NO), the accident notification control unit 31 repeats the process of determining whether or not the sound D that is equal to or higher than the sound threshold Dsh1 is input.

  When a sound D that is equal to or higher than the sound threshold Dsh1 is input (S201: YES), the accident notification control unit 31 reads out contact information A2 stored in the emergency contact table 12b in advance (S202). The accident notification control unit 31 displays a telephone call confirmation screen S2 on the display 3 based on the read information (S203).

  FIG. 7B is a diagram showing a display example of the telephone call confirmation screen S2.

  The call origination confirmation screen S2 includes a pop-up window area PW2 superimposed on the window area RW. The pop-up window area PW2 includes a message for detecting a traffic accident of a third party but confirming to the user whether to make a call to the contact information A2, and a CANCEL icon 201.

  The user can recognize that the mobile phone 1 is about to make a call to the emergency contact because the mobile phone 1 detects the occurrence of a traffic accident of a third party by looking at the call confirmation screen S2.

Returning to FIG. 7A, the accident notification control unit 31 determines whether or not a tap operation has been performed on the CANCEL icon 201 (S204). When the tap operation is not performed on the CANCEL icon 201 (S204: NO), the accident notification control unit 31 determines whether or not a predetermined time Tsh1 has elapsed since the telephone call confirmation screen S2 was displayed ( S205). The time Tsh1 is set to a time at which the user can determine whether or not it is necessary to make a call to the emergency contact after a third party traffic accident occurs.

  When the time Tsh1 has not elapsed since the telephone call confirmation screen S2 is displayed (S205: NO), the accident notification control unit 31 returns the process to S204 and performs a tap operation on the CANCEL icon 201 until the time Tsh1 has elapsed. Repeat the situation determination process. If a tap operation is performed on the CANCEL icon 201 after the time Tsh1 has elapsed since the telephone call confirmation screen S2 is displayed (S204: YES), the accident notification control unit 31 makes a call to the emergency contact. In step S202, the process returns to step S202 to determine again whether or not a third-party traffic accident has occurred.

  If the tap operation is not performed on the CANCEL icon 201 (S204: NO) and the time Tsh1 has elapsed since the telephone call confirmation screen S2 is displayed (S205: YES), the accident notification control unit 31 displays the emergency contact table. A telephone call is made to the contact information A2 read from 12b (S206).

  In this way, when a third party traffic accident is detected and a call is made to the contact information A2 stored in the emergency contact table 12b, the accident notification control unit 31 ends the accident notification control process. If the mobile phone 1 is not shut down, the accident notification control process is executed again to determine whether or not a third party traffic accident has occurred.

  As described above, according to the second embodiment, it is determined based on the audio signal (sound) from the audio input unit 15 whether or not a third party traffic accident, which is one of the accidents, has occurred. When a traffic accident of a third party is detected, a call is sent to the emergency contact information such as the police. Therefore, the user can quickly report a traffic accident of a third party without calling himself.

  Further, according to the second embodiment, after the telephone call confirmation screen S2 is displayed, even if the time Tsh1 has elapsed, if there is no tap operation on the CANCEL icon 201, a telephone address to the emergency contact is automatically transmitted. Therefore, even if it is difficult for the user to perform a tap operation on the mobile phone 1, a call can be made to the emergency contact.

  Furthermore, according to the second embodiment, the telephone call confirmation screen S2 is displayed before the telephone call, and the tap operation status for the CANCEL icon 201 from the user is determined. Therefore, when the mobile phone 1 inputs some loud sound due to a cause other than a traffic accident of a third party, the user prevents the emergency contact from being called by mistake by tapping the CANCEL icon 201. be able to.

  In the mobile phone 1, control processing related to a call is executed by the control unit 11 based on an audio signal from the audio input unit 15 including the microphone 5. In the second embodiment, the presence / absence of a traffic accident (accident) by a third party is detected using the microphone 5 that is also used for other functions, that is, other functions. Therefore, the presence or absence of an accident can be detected with a simple configuration without mounting a special sensor on the mobile phone 1.

<Example 3>
As an example of the accident, a case where the user's baggage of the user of the mobile phone 1 is snatched can be cited. The accident notification control unit 31 according to the third embodiment detects the occurrence of snatching for the user of the mobile phone 1 and transmits the current position information P1 to the emergency contact.

  FIG. 8A is a conceptual diagram illustrating an example in which a transition of a dynamic acceleration Gr generated in the mobile phone 1 and a sound D input by the mobile phone 1 when snatching occurs for a user. In FIG. 8A, the horizontal axis represents elapsed time (milliseconds), and the vertical axis represents dynamic acceleration (G) and sound volume (dB).

  Referring to FIG. 8A, the dynamic acceleration Gr generated in the mobile phone 1 changes with a very small value until the elapsed time t5. At the elapsed time t5, the baggage of the user wearing the mobile phone 1 is picked up. Then, the mobile phone 1 moves violently due to a large impact caused by snatching, and the dynamic acceleration Gr generated in the mobile phone 1 increases rapidly. Thereafter, the dynamic acceleration Gr generated in the mobile phone 1 reaches a maximum at the elapsed time t6, and then rapidly decreases and transitions at a very small value similar to that before the increase.

  In addition, after a large impact occurs on the mobile phone 1, the user of the mobile phone 1 or a third party screams at an elapsed time t7. Then, the sound D input by the mobile phone 1 increases rapidly. Thereafter, the sound D input by the mobile phone 1 reaches a maximum at the elapsed time t8, then decreases rapidly, and transitions at a slightly larger value than before the increase.

  As described above, in general, when snatching to the user occurs, the mobile phone 1 generates a dynamic acceleration that is extremely larger than the dynamic acceleration that occurs during normal use. Thereafter, during a short period of time, a sound that is extremely louder than the sound input by the mobile phone 1 during normal use of the mobile phone 1 is generated.

  Thus, in the third embodiment, as shown in FIG. 8A, a predetermined value that does not exceed the case of the dynamic acceleration that can occur during normal use and that exceeds the case of the dynamic acceleration that can occur when snatching occurs for the user. The acceleration threshold value Gsh2 is set. Furthermore, a predetermined sound threshold Dsh2 is set that does not exceed the case of sounds that can be generated during normal use, and that exceeds the case of sounds that can be generated when snatching occurs for the user. The accident notification control unit 31 monitors the magnitude of the dynamic acceleration (detection signal corresponding to the dynamic acceleration) output from the acceleration detection unit 22 and the sound (detection signal corresponding to the sound) output from the voice input unit 15. In the normal use of the sample telephone 1, a large dynamic acceleration not less than a predetermined acceleration threshold value Gsh2 is generated in the mobile phone 1, and then assumed in the normal use of the mobile phone 1 within a predetermined elapsed time. When the mobile phone 1 inputs a loud sound that is not obtained and exceeds a predetermined sound threshold Dsh2, it is considered that snatching has occurred for the user, and the current position information P1 is transmitted to the emergency contact.

  For example, if the dynamic acceleration generated in the mobile phone 1 during normal use is about 0 to 0.03 G, and the dynamic acceleration generated in the mobile phone 1 when the user falls is about 0.15 G, the acceleration threshold Gsh2 is It is set to 0.125G. Further, if the sound input by the mobile phone 1 during normal use is approximately 20 to 60 dB, and the sound input by the mobile phone 1 when a person screams is approximately 100 dB or more, the sound threshold Dsh2 Is set to 90 dB. In this way, by setting the acceleration threshold Gsh2 and the sound threshold Dsh2, it is possible to detect snatching for the user.

  FIG. 8B is an example of the accident reference information table 12a according to the third embodiment. FIG. 8C illustrates an example of the emergency contact table 12b according to the third embodiment.

As shown in FIG. 8B, the acceleration reference information table 12a stores the acceleration threshold value Gsh2 and the sound threshold value Dsh2 in advance. Further, as shown in FIG. 8C, the emergency contact table 12b stores contact information A3 of the other party who quickly catches the current position information P1.

  FIG. 9A is a flowchart illustrating the accident notification control process according to the third embodiment.

  The control process in FIG. 9A is started when the mobile phone 1 is activated. This control processing is executed in parallel with other control processing such as control processing of each application.

  Referring to FIG. 9A, the accident notification control unit 31 compares the acceleration threshold value Gsh2 with a detection signal (dynamic acceleration) from the acceleration detection unit 22, and the mobile phone 1 has a dynamic acceleration equal to or higher than the acceleration threshold value Gsh2. It is determined whether or not Gr has occurred (S301).

  When the mobile phone 1 does not have a dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh2 (S301: NO), the accident notification control unit 31 determines whether or not the mobile phone 1 has a dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh2. Repeat the process.

  When dynamic acceleration Gr equal to or higher than the acceleration threshold Gsh2 occurs in the mobile phone 1 (S301: YES), the accident notification control unit 31 compares the sound threshold Dsh2 with the voice input signal (sound) from the voice input unit 15, It is determined whether or not a sound D greater than or equal to the sound threshold Dsh2 has been input (S302).

  When the sound D that is equal to or greater than the sound threshold Dsh2 is not input (S302: NO), the accident notification control unit 31 determines whether or not a predetermined time Tsh2 has elapsed since the occurrence of the dynamic acceleration Gr that is equal to or greater than the acceleration threshold Gsh2. (S303). Time Tsh2 is set to the time it takes for the user or a third party to scream after snatching occurs for the user.

  When the predetermined time Tsh2 has not elapsed since the occurrence of the dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh2, the accident notification control unit 31 returns the process to S302 and continues until the time Tsh2 has elapsed. The process of determining whether or not the sound D of Dsh2 or higher is input is repeated.

  If the sound D that is equal to or higher than the sound threshold Dsh2 is not input (S302: NO) and the predetermined time Tsh2 has elapsed since the occurrence of the dynamic acceleration Gr that is equal to or higher than the acceleration threshold Gsh2 (S303: YES), the accident notification control unit 31 Returns the process to S301, and repeats the process of determining whether or not the mobile phone 1 has generated a dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh2.

  When a sound D that is equal to or greater than the sound threshold Dsh2 is input until a predetermined time Tsh2 elapses after the dynamic acceleration Gr that is equal to or greater than the acceleration threshold Gsh2 is detected (S302: YES), the accident notification control unit 31 includes the position detection unit 23. Thus, the current position information P1 is acquired (S304). The accident notification control unit 31 reads out the contact information A3 stored in the emergency contact table 12b in advance (S305). The accident notification control unit 31 displays a position transmission confirmation screen S3 on the display 3 based on the read current position information P1 and contact information A3 (S306).

  FIG. 9B is a diagram illustrating a display example of the position transmission confirmation screen S3.

The position transmission confirmation screen S3 includes a pop-up window area PW3 superimposed on the window area RW. The pop-up window area PW3 includes a message that detects snatching for the user, but confirms to the user whether or not to send the current position information P1 to the contact information A3, and a CANCEL icon 201.

  By viewing the position transmission confirmation screen S3, the user can recognize that the mobile phone 1 is trying to transmit the current position information P1 to the emergency contact because the mobile phone 1 detects snatching to the user.

  Returning to FIG. 9A, the accident notification control unit 31 determines whether or not a tap operation has been performed on the CANCEL icon 201 (S307). When the tap operation is not performed on the CANCEL icon 201 (S307: NO), the accident notification control unit 31 determines whether or not a predetermined time Tsh1 has elapsed since the position transmission confirmation screen S3 was displayed ( S308). The time Tsh1 is set to a time during which it is possible to determine whether or not it is necessary for the user to transmit the current position information P1 to the emergency contact address after snatching to the user occurs.

  If the time Tsh1 has not elapsed since the position transmission confirmation screen S3 was displayed (S308: NO), the accident notification control unit 31 returns the process to S307, and performs a tap operation on the CANCEL icon 201 until the time Tsh1 has elapsed. Repeat the situation determination process. If a tap operation is performed on the CANCEL icon 201 before the time Tsh1 has elapsed after the position transmission confirmation screen S3 is displayed (S308: YES), the accident notification control unit 31 sends the current position information to the emergency contact information. Without transmitting P1, the process returns to S301, and it is determined again whether snatching has occurred for the user.

  If the tap operation is not performed on the CANCEL icon 201 (S307: NO) and the time Tsh1 has elapsed since the position transmission confirmation screen S3 was displayed (S308: YES), the accident notification control unit 31 displays the emergency contact table. The current position information P1 is transmitted to the contact information A3 read from 12b (S309).

  Thus, when snatching is detected for the user and the current position information P1 is transmitted to the contact information A3 held in the emergency contact table 12b, the accident notification control unit 31 ends the accident notification control process. If the cellular phone 1 is not shut down, the accident notification control process is executed again, and it is determined whether snatching has occurred for the user.

  As described above, according to the third embodiment, based on the detection signal (dynamic acceleration) from the acceleration detection unit 22 and the audio signal (sound) from the audio input unit 15, whether or not snatching has occurred for the user who is one of the accidents. Determined. When snatching is detected, the current position information P1 is transmitted to the emergency contact address. Therefore, the user can promptly notify the emergency contact information of the current position information P1 where the snatching has occurred without performing an operation by himself / herself.

  Further, according to the third embodiment, detection signals of two types of sensors, that is, a detection signal (dynamic acceleration) from the acceleration detection unit 22 including the acceleration sensor and a detection signal (sound) from the voice input unit 15 including the microphone 5 are detected. The presence or absence of occurrence of an accident is determined by the combination. Therefore, complicated accident reference information can be set, and the detection accuracy of the accident can be further improved.

  Furthermore, according to the third embodiment, the current position information P1 is automatically transmitted if there is no tap operation on the CANCEL icon 201 even after the time Tsh1 has elapsed after the position transmission confirmation screen S3 is displayed. Therefore, even if the mobile phone 1 itself is stolen and it is difficult for the user to perform a tap operation on the mobile phone 1, the current location information P1 can be transmitted to the emergency contact.

  Further, according to the third embodiment, the position transmission confirmation screen S3 is displayed before the current position information P1 is transmitted, and the tap operation status for the CANCEL icon 201 from the user is determined. Therefore, when the mobile phone 1 inputs a loud sound after a strong impact is applied due to a cause other than snatching, the user accidentally sends the current location information P1 to the emergency contact by tapping the CANCEL icon 201. Can be prevented.

  Further, in the third embodiment, the presence or absence of snatching (accident) with respect to the user is detected using the acceleration sensor and the microphone 5 that are also used for other functions. Therefore, the presence or absence of an accident can be detected with a simple configuration without mounting a special sensor on the mobile phone 1.

  As in the third embodiment, when snatching is detected as an accident, the mobile phone 1 may be stolen. Therefore, after the CANCEL icon 201 is tapped, an authentication process is performed. Also good. For example, various authentication techniques such as fingerprint authentication and password input can be used for the authentication process. When the authentication process is performed, the notification to the emergency contact is stopped. On the other hand, if the authentication fails because the correct password is not entered, the notification of the emergency contact is not canceled, and a notification that the emergency contact has been caught is notified. If it is set as such an aspect, it can prevent that the notification to an emergency contact address is stopped by the snatcher.

  Further, in the case of snatching, since the position of the mobile phone 1 can change over time, the current position information P1 may be transmitted at regular intervals. According to such an aspect, the receiver can know the change in the current position information P1 of the mobile phone 1 over time.

<Example of change>
In the first embodiment, the control process when the user falls, the second embodiment performs the control process when a traffic accident of a third party occurs, and the third embodiment executes the control process when the snatching occurs for the user. However, the types of these accidents may be determined, and control processing according to the determined types of accidents may be executed.

  FIG. 10A is an example of the accident reference information table 12a according to the modified example. FIG. 10B is an example of the emergency contact address table 12b according to the modified example.

  As shown in FIG. 10A, in the accident reference information table 12a, the combination of the acceleration threshold value and the sound threshold value shown in the first to third embodiments is stored in association with the type of the accident. When the accident type is a user's fall, the acceleration threshold Gsh1 is associated with the fall and stored. When the type of the accident is a third party traffic accident, the sound threshold Dsh1 is stored in association with the third party traffic accident. When the type of accident is snatching for the user, acceleration threshold value Gsh2 and sound threshold value Dsh2 are stored in association with snatching. In the modified example, the acceleration threshold Gsh2 is set larger than the acceleration threshold Gsh1. The sound threshold Dsh2 is set smaller than the sound threshold Dsh1.

  Further, as shown in FIG. 10B, the emergency contact table 12b stores contact information A1, A2, A3 corresponding to each type of accident and a notification message notifying that an accident has occurred. .

FIG. 11 is a flowchart illustrating the accident notification control process according to the modification. In FIG. 11, for the sake of convenience, only control processes different from those in the first to third embodiments are shown, and the control processes common to the first to third embodiments are omitted.

  The control process of FIG. 11 is started by activation of the mobile phone 1. This control process is executed in parallel with other control processes such as a control process for each application.

  Referring to FIG. 11, accident notification control unit 31 compares acceleration threshold value Gsh1 with a detection signal (dynamic acceleration) from acceleration detection unit 22, and dynamic acceleration Gr greater than acceleration threshold value Gsh1 is generated in mobile phone 1. It is determined whether or not (S401).

  When the mobile phone 1 has no dynamic acceleration Gr greater than or equal to the acceleration threshold value Gsh1 (S401: NO), the accident notification control unit 31 compares the sound threshold value Dsh1 with the voice input signal (sound) from the voice input unit 15. It is then determined whether or not a sound D that is equal to or higher than the sound threshold Dsh1 is input (S402).

  If the dynamic acceleration Gr greater than the acceleration threshold Gsh1 has not occurred (S401: NO) and the sound D greater than the sound threshold Dsh1 has not been input (S402: NO), the accident notification control unit 31 returns the process to S401. The process for determining whether or not the mobile phone 1 has generated a dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh1 and the process for determining whether or not the sound D greater than or equal to the sound threshold Dsh1 has been input are repeated.

  When the dynamic acceleration Gr greater than the acceleration threshold Gsh1 does not occur (S401: NO) and the sound D greater than the sound threshold Dsh1 is input (S402: YES), the accident notification control unit 31 detects from the acceleration detection unit 22 Since the signal (dynamic acceleration) and the voice input signal (sound) from the voice input unit 15 match the accident reference information shown in FIG. 6A, it is determined that a third-party traffic accident has occurred. As a result, the accident notification control unit 31 executes a control process (S202 to S206) related to a telephone call for reporting a third party traffic accident shown in FIG. In the present modification, if YES is determined in the process of S204 in FIG. 7A, the process returns to S401 in FIG.

  When the dynamic acceleration Gr equal to or greater than the acceleration threshold Gsh1 occurs (S401: YES), the accident notification control unit 31 determines whether or not the dynamic acceleration Gr is equal to or greater than the acceleration threshold Gsh2 (S403).

  When the mobile phone 1 has no dynamic acceleration Gr equal to or greater than the acceleration threshold Gsh2 (S403: NO), the accident notification control unit 31 detects the detection signal (dynamic acceleration) from the acceleration detection unit 22 and the audio from the audio input unit 15. Since the input signal (sound) matches the accident reference information shown in FIG. 4A, it is determined that the user has fallen. Thereby, the accident notification control unit 31 executes the control process (S102 to S107) related to the e-mail transmission for notifying the user's fall shown in FIG. In this modification, if YES is determined in the process of S105 in FIG. 5A, the process returns to S401 in FIG.

  When dynamic acceleration Gr equal to or higher than the acceleration threshold value Gsh2 is generated in the mobile phone 1 (S403: YES), the accident notification control unit 31 compares the sound threshold value Dsh2 with the voice input signal from the voice input unit 15, and the sound threshold value Dsh2 It is determined whether or not the above sound D has been input (S404).

  When the sound D that is equal to or higher than the sound threshold Dsh2 is not input (S404: NO), the accident notification control unit 31 determines whether or not a predetermined time Tsh2 has elapsed since the detection of the dynamic acceleration Gr that is equal to or higher than the acceleration threshold Gsh2. Determination is made (S405).

If the predetermined time Tsh2 has not elapsed since the detection of the dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh2 (S405: NO), the accident notification control unit 31 returns the process to S404 and continues until the time Tsh2 has elapsed. The process of determining whether or not a sound D that is equal to or higher than the threshold value Dsh2 is input is repeated.

  If the sound D that is equal to or greater than the sound threshold Dsh2 is not input (S404: NO), and the predetermined time Tsh2 has elapsed since the detection of the dynamic acceleration Gr that is equal to or greater than the acceleration threshold Gsh2 (S405: YES), the accident notification control unit 31 indicates that the user has fallen because the detection signal (dynamic acceleration) from the acceleration detection unit 22 and the voice input signal (sound) from the voice input unit 15 match the accident reference information shown in FIG. judge. Thereby, the accident notification control unit 31 executes the control process (S102 to S107) related to the e-mail transmission for notifying the user's fall shown in FIG.

  When a sound D greater than or equal to the sound threshold Dsh2 is input after a predetermined time Tsh2 elapses after the dynamic acceleration Gr greater than or equal to the acceleration threshold Gsh2 is detected (S404: YES), the accident notification controller 31 causes the acceleration detector 22 Since the detection signal (dynamic acceleration) from the voice and the voice input signal (sound) from the voice input unit 15 match the accident reference information shown in FIG. 8A, it is determined that snatching has occurred for the user. Thereby, the accident notification control unit 31 executes control processing (S304 to S309) related to transmission of the current position information P1 to the emergency contact shown in FIG. In the present modification, if YES is determined in the process of S307 in FIG. 9A, the process returns to S401 in FIG.

  As described above, according to this modification, the type of accident is determined according to the detection signals of the acceleration detection unit 22 and the voice input unit 15. Depending on the type of the determined accident, a process of transmitting an e-mail containing a notification message informing that the accident has been detected, a call to the emergency contact, a process of transmitting the current location information P1, etc. are executed. The Therefore, the user can notify the emergency contact address by an appropriate means corresponding to the detected type of accident.

  Further, according to the present modification example, if there is no tap operation on the CANCEL icon 201 before the predetermined time Tsh1 elapses, the emergency contact is automatically notified. Therefore, even if it is difficult to operate the mobile phone 1 for some reason, the emergency contact can be notified.

  Further, according to the present modification example, a screen for confirming the notification to the emergency contact such as the mail transmission confirmation screen S1 is displayed on the display 3 before the notification to the emergency contact. Therefore, when an erroneous accident is detected, the user can prevent the emergency contact from being notified by mistake by tapping the CANCEL icon 201.

  Furthermore, in the present modification example, the presence / absence detection of the accident and the type determination of the accident are performed using the acceleration sensor and the microphone 5 that are also used for other functions. Therefore, it is possible to detect the presence / absence of the accident and determine the type of the accident with a simple configuration without mounting a special sensor on the mobile phone 1.

For example, in the configuration of the first embodiment, when a user's fall due to a sudden illness or the like is detected, a message notifying the occurrence of the user's fall is transmitted by e-mail. However, in addition to the message transmission or the message transmission Instead of this, at least one of outgoing call and transmission of current position information may be performed. Similarly, in the configuration of the second embodiment, when a traffic accident of a third party is detected, at least one of transmission of a message and transmission of current location information is performed in addition to or instead of calling. It may be done. Similarly, in the configuration of the third embodiment, when snatching is detected, at least one of transmission of a message and transmission of a phone call is performed in addition to or instead of transmission of the current position information. Also good.

  Further, in the first to third embodiments and the modified examples, predetermined functions (email transmission, telephone call, etc.) are executed after the accident detection. However, as shown in FIG. 12, the functions are executed by the user after the accident detection. An automatic notification selection screen S4 may be displayed on the display 3 so that a function can be selected.

  FIG. 12 is a diagram illustrating a display example of the automatic notification selection screen S4.

  The automatic notification selection screen S4 includes a pop-up window area PW4 superimposed on the window area RW. The pop-up window area PW4 includes a message indicating that the user has fallen, a mail transmission icon 211, a GPS notification icon 212, a telephone call icon 213, and a CANCEL icon 201.

  When a tap operation is performed on the mail transmission icon 211, the accident notification control unit 31 transmits an e-mail with a notification message informing that the user has fallen to the emergency contact information. When a tap operation is performed on the GPS notification icon 212, the accident notification control unit 31 transmits the current position information when the user falls down to the emergency contact information. When a tap operation is performed on the telephone call icon 213, a telephone call is made to the emergency contact.

  In this way, after an accident occurs, the user can select an appropriate function according to the situation. In this case, when the tap operation is not performed on the CANCEL icon 201 for a certain period of time, it is desirable that the emergency contact is notified by one predetermined function (for example, e-mail).

  In the first to third embodiments and the modified examples, when the tap operation is performed on the CANCEL icon 201, the notification to the emergency contact is stopped. However, in addition to the home key 105b and the back key 105c, When other terminal operations such as a tap operation are performed, the notification to the emergency contact may be stopped.

  In addition to the CANCEL icon 201, or instead of the CANCEL icon 201, an icon for immediately sending a message to the emergency contact may be arranged. In this case, the user can immediately notify a message to the emergency contact by performing a tap operation on the icon.

  Moreover, in the said Examples 1-3 and a modification, although the confirmation screen (S1-S4) was displayed before the notification to an emergency contact address, when a confirmation screen is not displayed and an accident is detected, Notification to the emergency contact may be automatically started.

  Moreover, the screen display in the said Examples 1-3 and a modification is an example, and is not restricted to this. For example, the confirmation screen may be displayed not on the pop-up window areas PW1 to PW4 but on the entire window area RW of the display 3.

  In the first to third embodiments and the modified example, the occurrence of the accident is notified to the emergency contact by e-mail. However, the occurrence of the accident is urgent by other means (message function) such as SMS and web access. The contact may be notified.

  In the above embodiment, the value of the dynamic acceleration detected by the acceleration detector 22 is compared with the acceleration threshold value Gsh1, whereby an accident (falling due to sudden illness, traffic accident, etc.) is detected. However, the temporal change pattern of the dynamic acceleration caused by the occurrence of an accident (falling due to sudden illness, traffic accident, etc.) is stored as the reference acceleration information in the accident reference information table 12a, and the dynamic acceleration detected by the acceleration detecting unit 22 is stored. The occurrence of an accident may be detected by the accident notification control unit 31 when the result of the comparison between the change pattern and the time change pattern of the dynamic acceleration that is the reference acceleration information indicates that the two time change patterns match. Similarly, a time change pattern of sound resulting from the occurrence of an accident (such as a third-party traffic accident) is stored in the accident reference information table 12a as reference sound information and detected by the voice input unit 15. The occurrence of an accident may be detected by the accident notification control unit 31 when the time change patterns of the sound and the time change pattern of the sound that is the reference sound information match.

  Further, in the above embodiment, it is determined that the accident has occurred when the dynamic acceleration exceeds a predetermined value regardless of the direction, but the accident is determined based on whether the dynamic acceleration in the front-rear direction exceeds the predetermined value. The presence or absence of occurrence may be determined. By adopting such an aspect, for example, it is possible to more accurately determine the presence or absence of an accident with respect to an accident that is assumed to have a greater displacement in the front-rear direction than in the left-right direction and the up-down direction, such as a fall. Can do.

  In the above embodiment, the call voice is output from the call speaker 6. However, the call voice may be output from a speakerphone having a voice input and a voice output function.

  In the above embodiment, the mail transmission confirmation screen S1 and the like are displayed on the display 3 for a predetermined time Tsh1 until a tap operation is performed on the CANCEL icon 201. However, in addition to such a mode or in place of such a mode, it may be notified that a notification to the emergency contact is awaited by sound or vibration.

  When a loud sound is detected as in the second embodiment, a recording function may be executed to store surrounding sounds. In this case, the stored recording data is transmitted to a desired contact address based on a user operation or automatically attached to an e-mail or the like. According to such an aspect, the situation around the user can be stored, and a desired contact can be notified as necessary.

  The present invention is not limited to a mobile phone, and can be applied to various mobile terminal devices such as a PDA (Personal Digital Assistant), a tablet PC (Tablet PC), and an electronic book terminal.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
