At this time, in FIG. 2, the same member numbers as the respective constituent members of the terminal device S are used for each constituent member of the embodiment corresponding to each constituent member of the terminal device S according to the embodiment shown in FIG. .

As shown in FIG. 2, the smartphone SP according to the embodiment is configured to be fixable, for example, on a dashboard in a vehicle (not shown), and includes an interface 10, a CPU, a RAM (Random Access Memory), and a ROM (Read Only Memory) etc., memory 12 such as SSD (Solid State Drive), display 13 such as liquid crystal display, speaker 14, operation buttons or touch panel etc. provided on the surface of display 13 and the acceleration sensor 1 . Further, the processing unit 11 is composed of the state management/information processing module 2 , the display control unit 16 connected to the display 13 , and the audio reproduction unit 17 connected to the speaker 14 . At this time, each of the state management/information processing module 2, the display control unit 16, and the audio reproduction unit 17 may be configured by a hardware logic circuit such as the above-described CPU that configures the processing unit 11, or may be implemented as described later. A program corresponding to the communication processing according to the example may be implemented in software by the CPU of the processing unit 11 reading and executing the program. The acceleration sensor 1 corresponds to an example of the detection means 1 according to the embodiment, the state management/information processing module 2 corresponds to an example of the notification means 2 according to the embodiment, an example of the determination means 3 and an example of the prohibition means 4, correspond respectively.

In the configuration of the smartphone SP described above, the interface 10 controls transmission/reception of data to/from a network (not shown) related to the external notification under the control of the state management/information processing module 2 . Further, the display control unit 16 controls display contents on the display 13 under the control of the state management/information processing module 2 . Thereby, the display 13 displays necessary information under the control of the display control section 16 . On the other hand, under the control of the state management/information processing module 2, the audio reproduction unit 17 executes processing for synthesizing sounds or voices to be emitted from the speaker 14, and the like. Thereby, the speaker 14 emits sound corresponding to the sound data generated by the sound reproduction unit 17 or sound corresponding to the generated sound data. On the other hand, the acceleration sensor 1 detects acceleration corresponding to the impact applied to the smartphone SP, generates acceleration data indicating the magnitude and direction of the acceleration, and outputs the generated acceleration data to the state management/information processing module 2 . Thereby, the state management/information processing module 2 analyzes the content of the acceleration data from the acceleration sensor 1 and generates impact data indicating the magnitude and direction of the impact corresponding to the acceleration. Further, when the operation unit 15 is operated by the user to specify the operation of the smartphone SP, the operation unit 15 generates an operation signal corresponding to the operation and outputs the operation signal to the state management/information processing module 2. do. Based on the operation signal from the operation unit 15, the state management/information processing module 2 controls the interface 10, the display control unit 16, and the audio reproduction unit 17, respectively, while performing communication processing according to the embodiment. mainly run. In addition, the state management/information processing module 2 is the smartphone S
It centrally controls processing other than communication processing according to the embodiment as P. Data required for processing in the state management/information processing module 2 are recorded in the memory 12 as necessary, and further read out from the memory 12 as necessary.

Next, communication processing according to an embodiment by the smartphone SP having the above-described configuration will be specifically described with reference to FIGS. 2 to 4. FIG.

As shown in the flowchart of FIG. 3, the communication process according to the embodiment is started at the timing when the power switch (not shown) of the smartphone SP is turned on, for example. Further, at this time, the smartphone SP according to the embodiment is sandwiched vertically by the gripping portion 21 and the gripping portion 22 on a dashboard of a vehicle (not shown), for example, as illustrated in FIG. It is fixed to the fixed part 20 . The position of the smartphone SP when it is fixed to the fixing portion 20 corresponds to an example of the "first position" according to the present application. As a method for fixing the smartphone SP according to the embodiment, in addition to fixing by the gripping portion 21 and the gripping portion 22, for example, it may be fixed by placing it on a stand fixed on a dashboard or the like. .

Then, when the communication process according to the embodiment is started, the state management/information processing module 2 of the smartphone SP waits for changes in the state, posture, etc. of the smartphone SP itself, and while it is being fixed to the fixing unit 20, the acceleration The magnitude and direction of the gravitational acceleration detected by the sensor 1 are non-volatilely recorded in the memory 12 as the initial value of the gravitational acceleration (step S1). When the smartphone SP is tilted and fixed from the viewpoint of use, the initial value of the gravitational acceleration is the force component of the gravitational acceleration corresponding to the tilt. Next, the state management/information processing module 2 determines whether or not the magnitude of acceleration indicated by the acceleration data output from the acceleration sensor 1 exceeds a preset acceleration threshold value recorded in the memory 12 . Determine (step S2). Here, the acceleration threshold is, for example, an acceleration threshold corresponding to acceleration (impact) to the extent that the smartphone SP according to the embodiment falls off from being fixed by the fixing unit 20, and more specifically, the smartphone SP. is preset empirically or experimentally according to the fixing method or mode (see FIG. 4(a)). In the determination in step S2, if the magnitude of the acceleration indicated by the output acceleration data is not equal to or greater than the acceleration threshold (step S2: NO), the smartphone SP is regarded as not out of the fixed position by the fixing unit 20, and state management is performed. - The information processing module 2 returns to step S1. On the other hand, if it is determined in step S2 that the magnitude of the acceleration indicated by the output acceleration data is equal to or greater than the acceleration threshold (step S2: YES), the state management/information processing module 2 next causes the display control unit 16 to 4(b) is displayed on the display 13. As shown in FIG. In addition, the state management/information processing module 2 uses a timer (not shown) to start timing a preset threshold time as the time from the application of an acceleration equal to or greater than the acceleration threshold until the external notification is made. do. As a result, the state management/information processing module 2 and the display control unit 16, as exemplified in FIG. The display 13 displays "message transmission" to notify the outside that the acceleration of the above magnitude is applied, together with the cancel button 31 operated by the user when the external notification is not performed (to cancel). (step S3).

Next, the state management/information processing module 2 determines that the value of the gravitational acceleration at the present time after the acceleration having a magnitude equal to or greater than the acceleration threshold is applied to the smartphone SP is the initial value recorded in the memory 12 in step S1. It is determined whether or not they are substantially equal (step S4). If the current value of the gravitational acceleration is substantially equal to the initial value in step S4 (step S4: YES), the state management/information processing module 2 determines that the smartphone SP remains fixed to the fixing unit 20. Then, it is determined whether or not the threshold time has passed (step S10). If the threshold time has not elapsed since the acceleration equal to or greater than the acceleration threshold was detected (step S2: YES) in the determination of step S10 (step S10: NO), then the state management/information processing module 2 It is determined whether or not the cancel button 31 illustrated in 4(b) has been operated (step S11). If the cancel button 31 has not been operated in step S11 (step S11: NO), the state management/information processing module 2 returns to step S10 to continue timekeeping. On the other hand, if the cancel button 31 has been operated in the determination of step S11 (step S11: YES), the state management/information processing module 2 displays the report cancellation screen illustrated in FIG. 4(c) on the display 13 (step S12), and then waits until a predetermined time elapses (step S13, step S13: NO). Then, when the certain period of time has passed (step S13: YES), the state management/information processing module 2 stops displaying the notification cancellation screen and, for some reason, turns off the power switch of the smartphone SP. It is determined whether or not to end the communication process according to the example (step S16). If the process is terminated in the determination of step S16 (step S16: YES), the state management/information processing module 4 terminates the process. On the other hand, if the determination in step S16 is to continue the process (step S16: NO), the state management/information processing module 4 returns to step S1 and repeats the series of processes described above.

On the other hand, when the threshold time has elapsed since the acceleration equal to or greater than the acceleration threshold was detected (step S2: YES) in the determination of step S10 (step S10: YES), then the state management/information processing module 2 and the display The control unit 16 makes the external report and displays an external report screen to the effect that the external report has been made on the display 13 (step S14), and then waits for the passage of a predetermined time (step S15, Step S15: NO). When the predetermined time has passed (step S15: YES), the state management/information processing module 2 stops displaying the external report screen and proceeds to step S16. Note that the external notification in step S14 is executed by one or more of the following methods, for example.
i) Sending emails to preset destinations
ii) Phone calls to preset parties
iii) Report via VICS (registered trademark) (Vehicle Information Communication System) capable of communication
iv) Report by so-called vehicle-to-vehicle communication or vehicle-to-walk communication On the other hand, if the current value of the gravitational acceleration is different from the initial value in the determination in step S4 (step S4: NO), the state management/information processing module 2 Assuming that the smartphone SP is detached from the fixing portion 20 and is falling, for example, it is next determined whether or not the threshold time has elapsed (step S5). If the threshold time has elapsed since the acceleration equal to or greater than the acceleration threshold was detected (step S2: YES) in the judgment of step S5 (step S5: YES), then the state management/information processing module 2 and display control The unit 16 proceeds to step S14. Next, when the threshold time has not elapsed in the determination of step S5 (step S5: NO), the state management/information processing module 2 determines that the value of the gravitational acceleration currently applied to the smartphone SP is the step It is determined again whether or not it is approximately equal to the initial value recorded in the memory 12 in S1 (step S6). Here, if the smartphone SP, which once fell off the fixing portion 20 (see step S4: NO), is fixed to its original position, the determination in step S6 should be "YES". Therefore, when the value of the gravitational acceleration currently applied to the smartphone SP is substantially equal to the initial value in the determination of step S6 (step S6: YES), the state management/information processing module 2 performs the external notification. Instead, the notification cancel screen shown in FIG. 4C is displayed on the display 13 (step S8), and then the system waits for a predetermined period of time to elapse (step S9, step S9: NO). Note that the position of the smartphone SP when it is fixed again corresponds to an example of the "second position" according to the present application. When the predetermined time has passed (step S9: YES), the state management/information processing module 2 stops displaying the notification cancel screen and proceeds to step S16.

On the other hand, if the value of the gravitational acceleration currently applied to the smartphone SP is different from the initial value in the determination of step S6 (step S6: NO), the state management/information processing module 2 next determines that the currently displayed (See step S3) It is determined whether or not the cancel button 31 has been operated (step S7). If the cancel button 31 has not been operated in step S7 (step S7: NO), the state management/information processing module 2 returns to step S5 and repeats the series of processes described above. Next, when the cancel button 31 is operated in the determination of step S7 (step S7: YES), the state management/information processing module 2 proceeds to step S8.

As described above, according to the communication processing according to the embodiment by the smartphone SP, in the case where an external report is made in response to the application of acceleration equal to or greater than the predetermined threshold, the position of the smartphone SP after detecting the application is Since the external report is prohibited when the position corresponding to the position after the smartphone SP moves from the position before the application detection (see step S6 in FIG. 3: YES), the operation when the report is unnecessary is simplified. can be customized to improve its usability.

Further, the smartphone SP is provided with the acceleration sensor 1, and when the gravitational acceleration detected by the acceleration sensor can be considered to be the same before and after application of the acceleration equal to or greater than the threshold acceleration, it is determined that the smartphone SP has been returned to its original position. Therefore, the determination can be made with a simple configuration (see step S6 in FIG. 3: YES).

In addition to determining the change in the position of the smartphone SP based on the gravitational acceleration in the above-described embodiment (that is, whether it has fallen from the fixed part 20), the following method is used to determine the change in the position. can do.
i) Smartphone SP when wireless communication is established between a communication unit that is provided at the original fixed position and complies with the NFC (Near Field Communication) standard and a communication unit that is provided in the smartphone SP and complies with the NFC standard. is not changed (that is, it is returned to the position of the fixed part 20 (the same applies hereinafter)).
ii) When the imaging result by the camera of the smart phone SP can be considered to be the same before and after application of acceleration equal to or greater than the acceleration threshold, it is determined that there is no change in the position of the smart phone SP. In this case, the camera corresponds to an example of the "imaging means" according to the present application.
iii) If the smartphone SP is provided with an air pressure sensor and the detection result of the air pressure by the air pressure sensor can be regarded as the same before and after application of acceleration equal to or greater than the acceleration threshold, there is no change in the position (especially height) of the smartphone SP. I judge. In this case, the atmospheric pressure sensor corresponds to an example of the "air pressure detecting means" according to the present application.
iv) The fixing unit 20 (see FIG. 4) is provided with a button or the like that is pressed when the smartphone SP is held, and when the button or the like is pressed after application of acceleration equal to or greater than the acceleration threshold, the position of the smartphone SP It is determined that there is no change in In this case, the button or the like corresponds to an example of the "pressing means" according to the present application.
v) If the gripping portion 21 and the gripping portion 22 of the fixed portion 20 are expanded (opened) after the application of the acceleration equal to or greater than the acceleration threshold, it is determined that the position of the smartphone SP has not changed. In this case, the gripping portion 21 and the gripping portion 22 correspond to an example of the "gripping means" according to the present application.
vi) When the fixed unit 20 and the smartphone SP can communicate wirelessly with each other, if the communication distance can be considered to be the same before and after applying an acceleration equal to or greater than the acceleration threshold, it is determined that the position of the smartphone SP has not changed. do. In this case, the wireless communication means corresponds to an example of the "communication means" according to the present application.
vii) When the smartphone SP is connected to another device by a connection line having a connection end on the fixed part 20, the smartphone SP detects that the connection line has been connected after the acceleration equal to or greater than the acceleration threshold is applied. Sometimes, it is determined that there is no change in the position of the smartphone SP.

The method using gravitational acceleration according to the embodiment and the methods described in i) to vii) above may be used alone, or two or more of the methods may be used in combination.

Further, the acceleration thresholds according to the embodiment are a front acceleration threshold for acceleration due to impact from the front, a rear acceleration threshold for acceleration due to rear impact, and a side acceleration threshold for acceleration due to side impact. may be different values. Furthermore, although the threshold time is normally 10 seconds, the larger the acceleration threshold, the shorter it may be so that the external notification can be executed quickly.

Also, a program corresponding to the flowchart shown in FIG. 3 is recorded on a recording medium such as an optical disk or hard disk, or obtained via a network such as the Internet, and is read by a general-purpose microcomputer or the like. By executing this, it is also possible to cause the microcomputer or the like to function as the processing unit 11 according to the embodiment.
