Description

  The present invention relates to a portable device that is an information processing device carried by a user, a control method for the portable device, and a control program, and more particularly, to an emergency data recording function of the portable device.

  Some portable devices such as cellular phones have a function of acquiring information (for example, image information, position information, audio information, and the like) in the event of an emergency and transmitting it to a predetermined receiving device as a crime prevention function. (For example, see Patent Documents 1 and 2).

  For example, in Patent Document 1, when an emergency button is pressed, a control unit that detects the activation activates a camera unit, a position information recognition unit, and a clock unit to acquire information (crime scene information) and store the storage unit. And a mobile terminal with a crime prevention function that transmits the crime scene information stored in the storage unit and information related to the owner of the terminal to a pre-stored mail address.

  In addition, for example, in Patent Document 2, when the emergency is detected by the detection unit that detects an emergency, the location information and the surrounding information of the user are acquired when the emergency is detected. In addition, a portable terminal that transmits the acquired position information and surrounding information to a predetermined server is described.

JP 2004-289364 A JP 2005-39700 A

  In the portable terminal described in Patent Document 1, the emergency button is triggered, and the acquisition of the crime scene information and the transmission of the e-mail are continuously executed as a series of operations. It also makes it possible to send crime scene information to emergency contacts. However, the user of the mobile terminal may not always be able to press the emergency button in an emergency. For example, when the emergency button cannot be pressed such as a situation where it is difficult to touch the mobile terminal, information indicating the situation at that time is displayed. It cannot be acquired and stored or transmitted. Moreover, since the crime scene information acquired after pressing the emergency button does not include surrounding information up to the situation, it may be insufficient as information. When an emergency occurs, information (especially the latest information) that indicates the situation up to the emergency can be valuable information in the event of an unexpected incident or accident. In the case of a portable terminal, the latest information cannot be retained in an emergency.

  In addition, in the portable terminal described in Patent Document 2, for example, when a help key is operated, it is detected that there is an emergency, and self-location is acquired, surrounding scenery is photographed, and ambient sounds are collected. , Stored in RAM. Note that if the mobile terminal described in Patent Document 2 is used, depending on the detection method that indicates an emergency, even if the user cannot press the button, information indicating the situation at that time is acquired. Might be able to send. However, Patent Literature 2 does not disclose any method other than detecting that an emergency has occurred when a help key is operated. Further, in the method of acquiring surrounding information when it is detected that there is an emergency, there is a problem that the latest information until the emergency is detected cannot be acquired, as in Patent Document 1.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a mobile phone which is an embodiment of the mobile device of the present invention. The mobile phone 1 according to the present invention includes, in addition to a function unit for realizing a communication service as a mobile phone, a function unit for recording surrounding sounds, a function unit for acquiring a current position, A function unit for acquiring date and time information and a function unit for inputting a password from the user are provided. More specifically, as shown in FIG. 1, the control unit 11, the memory 12, the communication unit 13, the display unit 14, the microphone (microphone) 15, the speaker 16, the key 17, and the vibrator 18 , A camera 19, a GPS receiver 20, and a timer 21.

  The control unit 11 is a processor unit that controls the operation of each functional unit included in the mobile phone 1 and operates according to a program such as a CPU. The memory 12 is a storage device that stores programs executed by the control unit 11 and various data.

  The communication unit 13 performs communication (data transmission / reception) with a base station in a communication system that provides a communication service subscribed to by an external device or the mobile phone 1. For example, in the case of the communication unit 13 that performs communication with a base station, the communication unit 13 is realized by a radio unit that transmits and receives radio signals and a device that processes radio signals.

  The display unit 14 displays information. The display unit 14 is realized by, for example, an output device such as a monitor and a device for driving the output device.

  The microphone 15 collects surrounding sounds (including voices of users or people nearby) and outputs the collected voice data. The speaker 16 outputs the input audio data as an analog sound.

  The key 17 inputs key information assigned in advance according to a user operation. In addition to the key 17, an input device for inputting information for user authentication (such as fingerprint information) may be provided. The vibrator 18 generates vibration in accordance with control from the control unit 11.

  The camera 19 captures the surrounding situation and outputs image data. The camera 19 is realized by, for example, an imaging module that captures an image such as a CCD or CMOD, and a device that encodes and processes the image captured by the imaging module.

  The GPS receiving unit 20 receives a GPS signal output by GPS (Global Positioning System), and acquires position information (latitude and longitude) of the mobile phone 1.

  The timer unit 21 measures time and outputs clock information. The timer unit 21 is realized by, for example, RTC (Real Time Clock).

  Hereinafter, the operation of this embodiment will be described. In the present invention, an ambient situation recording mode is implemented in which information indicating the ambient situation (hereinafter, ambient situation data) is continuously recorded at regular intervals, and the end of the ambient situation recording mode (that is, continuous ambient situation data) By detecting that the user has not entered a password for continuation of recording, the ambient state data acquired and stored up to that point is not overwritten and erased. This ensures that the latest ambient status data is retained in the memory 12 when the user is unable to operate due to an accident or accident.

  FIG. 2 is a flowchart showing an example of the operation of the present embodiment. In the present embodiment, as ambient condition data, audio data recording ambient audio, position information indicating the current position at that time, and date / time information indicating the date and time when these pieces of information are acquired are associated with each other in the memory. An example of storing will be described. In the example shown in FIG. 2, when a recording start operation is performed from the user via the key 17 as an operation for instructing the start of the ambient state recording mode (step S <b> 101), the control unit that has accepted the fact (recording start operation) 11 shifts to the ambient condition recording mode, starts the recording process, and resets (starts up) the recording continuation timer (steps S102 and S103).

  For example, as a recording operation start operation, the control unit 11 may instruct the microphone 15 to start collecting sound and start outputting audio data for a predetermined time. In addition, after starting the recording process, the control unit 11 intermittently causes the microphone 15 to collect sound and output sound data. For example, after receiving the voice data output notification and collecting the voice data, the voice data may be intermittently output by instructing the start of sound collection again. If the recording process is continuing, the control unit 11 stores the audio data taken from the microphone 15 in the memory 12 each time.

  The recording continuation timer is a timer for measuring a recording continuation time, which is a time during which the recording process can be continued without a user's continuation instruction, and until the recording continuation timer expires, that is, the recording continuation time has elapsed. Until this is done, audio data (more specifically, ambient condition data including audio data) can be stored in the memory intermittently. As long as the recording duration (that is, the set value of the recording duration timer) is within the range allowed by the memory capacity and device performance, the interval is arbitrary. Specifically, any interval may be used as long as the surrounding state data corresponding to the recording duration, which is the set value of the recording continuation timer, can be held in the memory as the latest data in an emergency, but frequently continues to the user. It is preferable that the interval is long enough not to make the operator feel complicated.

  When the control unit 11 detects that the preset recording duration has elapsed by the timing process of the recording duration timer (Yes in step S104), the control unit 11 generates a sound from the speaker 16 or a vibration by the vibrator 18 to the user. The end of the recording duration is notified (step S108). At that time, the control unit 11 uses the display unit 14 to prompt the user to input a password, and if a regular password is input within a predetermined time (Yes in step S109), the control unit 11 remains in the ambient state recording mode. If there is, the recording continuation timer is reset again to continue the recording process (return to step S103). For example, the control unit 11 may compare the input password with a user password registered in advance and determine whether or not a regular password has been input when the two match.

  On the other hand, when the user is requested to input a password, but the password is not input within a predetermined time (No in step S109), the ambient state recording mode is terminated. In the present embodiment, the recording process is stopped as a process for ending the ambient condition recording mode (step S107). The control unit 11 may instruct the microphone 15 to end the sound collection and stop the output of the audio data as the recording process stop operation. Note that the control unit 11 may collect the audio data collected from the microphone 15 before storing the recording process and store it in the memory 12 as the latest audio data.

  In addition, when the control unit 11 detects that a preset current position positioning time interval has elapsed during the continuation of the recording process (Yes in step 105), the control unit 11 uses the GPS receiving unit 20 to measure the current position ( Step S110). For example, when the recording process is started, the control unit 11 may start the time measurement of the positioning interval timer. The positioning interval timer is a timer for intermittently measuring a current position positioning time interval, which is an interval for performing processing for acquiring the current position, and acquires the current position every time the positioning interval timer expires. The current position positioning time interval (that is, the setting value of the positioning interval timer) can be set as long as the memory capacity and device performance allow, but it can detect changes in position more precisely. If it is desired, a small value is preferable. In this embodiment, the recording continuation timer and the positioning interval timer are provided separately so that the current position can be measured a plurality of times during the set recording continuation time.

  Information on the current position acquired each time the positioning interval timer expires is stored in the memory 12 as a part of the surrounding state data. For example, the control unit 11 separately stores information on the current position acquired from the GPS receiving unit 20 as current position information, and reflects the information in the surrounding situation data by referring to the timing of storing the voice data in the memory. 12 may be stored. Further, for example, when the positioning interval timer expires, the voice data for one time may be taken from the microphone 15, and the positioning of the current position and the acquisition of the voice data may be performed by a series of processes.

  In addition, when storing the surrounding state data in the memory 12, the control unit 11 repeatedly uses a pre-sized memory area, so that the latest data is always held in the memory 12. Control the writing position to overwrite.

  The control unit 11 terminates the ambient situation recording mode by not inputting the password when the recording duration time has elapsed, and in addition, when the user performs a recording termination operation as an operation for instructing the termination of the ambient situation recording mode. Also (Yes in step S106), the ambient condition recording mode is terminated. That is, the recording process is stopped (step S107).

  FIG. 3 is an explanatory diagram illustrating an example of storing the ambient state data in the memory. FIG. 3 shows an example in which the memory 12 is sized so that n pieces of ambient condition data can be stored. FIG. 3 shows an example in which the storage data 0 area is an area storing the oldest ambient state data. In such a case, the control part 11 should just overwrite newly acquired surrounding condition data on the storage data 0 area | region which is an area | region where the oldest surrounding condition data are stored. At the next timing, the stored data 1 area, which is the area in which the oldest surrounding situation data is stored at that time, may be overwritten. In the example shown in FIG. 3, date / time information, position information, and audio data are stored as the surrounding state data.

  It should be noted that the acquisition / recording process of the periodic situation data in the ambient situation recording mode is preferably executed independently of the normal operation by using, for example, an interrupt process from the device.

  In the above example, the audio data, the position information, and the date / time information are stored as the surrounding state data. However, for example, the surrounding image data is acquired using the camera function unit 19 at the timing of storing in the memory 12 However, it can also be included in ambient situation data.

  As described above, according to the present embodiment, by detecting that there is no user operation and stopping the recording process, it is possible to prevent the ambient condition data that has been intermittently stored so far from being overwritten. Therefore, even if the user encounters an unexpected incident or accident and becomes unable to operate, if the ambient status recording mode is in effect, the latest data up to that point is retained in the memory. I can keep it. That is, by using the user operation for continuation of recording (that is, overwriting permission), the method of stopping the recording process upon receiving the user operation or the method of automatically stopping the recording after a predetermined time has surely been retained. It makes it possible to save the latest data that could not be kept.

  Also, in the above example, an example is shown in which a password input is requested in order to confirm to the user whether or not to continue recording. However, not only the password input but also information that can be confirmed by the user's own operation Any method may be used as long as it is an input and user authentication method. For example, it is possible to input fingerprint information and compare the fingerprint information of the user registered in advance to determine whether or not the operation is performed by the user himself / herself.

  In the present embodiment, the case where the mobile device is a mobile phone has been described as an example. However, the mobile device may be a portable information processing device such as an IC recorder or a music playback device.

  When the mobile device has a communication function, when the user does not perform a password input operation, the communication function may be used to notify the occurrence of an abnormality. At that time, the stored ambient condition data may be transmitted. For example, in the above example, when the user does not perform a password input operation, the control unit 11 further controls the communication unit 13 to transmit a preset message to a preset destination. You may make it notify generation | occurrence | production of abnormality. The means for transmitting the message may be voice communication, data communication, or electronic mail. When notification by data communication or e-mail is performed, ambient state data held in the memory 12 may be transmitted at that time.

  Further, when the current position information can be obtained from the base station, it can also be obtained by the communication unit 13.

  Next, the outline of the present invention will be described. FIG. 4 is an explanatory diagram showing an outline of the present invention. The mobile device 100 of the present invention includes a user operation accepting unit 101, an ambient condition data acquiring unit 102, a storage unit 103, and a control unit 104.

The ambient condition data acquisition unit 102 (for example, the microphone 15, the camera 19, and the GPS receiver 20) acquires ambient condition data that is data indicating the ambient condition of the mobile device 100. The storage unit 103 (for example, the memory 12) is a storage device having a memory area for storing at least one record data of a predetermined format including ambient condition data. The control unit 104 stores recording data including the latest ambient condition data in a memory area of a predetermined size in the storage unit 103. When a plurality of recording data can be stored in the memory area, the control unit 104 always overwrites the latest recording data by overwriting the data from the oldest time when the latest recording data is stored. Is stored.

  When a predetermined operation for continuation by the user is performed via the user operation reception unit 101, the control unit 104 continues the storage process of the recording data including the latest ambient state data in the memory area. This means that when a predetermined operation for continuation by the user is not performed via the user operation receiving unit 101, the storage process of at least the recording data including the latest ambient state data in the memory area is stopped. means.

  With such a configuration, it is possible to store information indicating the surrounding situation at the time immediately before the emergency.

  In addition, as a predetermined operation for continuation by the user, the control unit 104 performs an input operation of authentication information that is information that can be authenticated using information registered in advance that the operator is a regular user. It may be determined whether or not it has been received. The authentication information may be a password, for example.
