FIG. 1 shows mobile terminals 100A to 100N (hereinafter collectively referred to as "mobile terminals 100"), a server device 200, an advertising terminal 300, and a network 400, which will be described below.

The mobile terminal 100 is a general term for, for example, a smartphone, a personal computer, a tablet device, a PDA, a mobile phone, etc., which are operated by a user. The mobile terminal 100 is not limited to these functions as long as it has a calculation function and a communication function. Hereinafter, in this embodiment, a case where the mobile terminal 100 is a smartphone 100 will be described as an example.

The server device 200 is managed by a service provider of the mobile terminal system of this embodiment. The server device 200 mainly registers various information including contact information of the user who operates the mobile terminal 100, his family, etc., and provides the mobile terminal service of this embodiment to the user.

The advertising terminal 300 displays the notification application during foreground processing on the smartphone 100 in which a mobile terminal notification program (hereinafter simply referred to as "notification application") for receiving the mobile terminal service of the present embodiment is installed. This is a device that distributes advertisements displayed on . The type of advertisement distributed by advertising terminal 300 does not matter. For example, impression type, where advertising fees are charged depending on the number of times the ad is displayed, click type, where advertising fees are charged depending on the number of times the ad is clicked, and when an app is downloaded from an ad. Examples include success-based advertising that incurs advertising fees.

The network 400 is a general term for various networks such as the Internet and a mobile phone network. Note that the network 400 in a broad sense includes wireless networks such as Wi-Fi and Bluetooth, and local area networks installed in offices, homes, and the like.

FIG. 2 is a schematic internal configuration diagram of the mobile terminal (smartphone) 100A shown in FIG. 1. The mobile terminal 100A shown in FIG. 2 includes a communication means 110A, a display means 120A, a reception means 130A, a storage medium 140A, an acceleration sensor 150A, a comparison means 160A, a notification means 170A, and a control means, which will be described below. 180A. Similarly, for example, the smartphone 100B includes means 110B to 180B corresponding to each of the above-mentioned means 110A to 180A.

Here, if a certain user A owns a smartphone 100A and user A has left the smartphone 100A somewhere, user B (for example, user A's parent, child, spouse, etc.) The explanation will be based on the assumption that a person (typically) owns a smartphone 100B, a notification app is installed on both smartphones 100A and 100B, and the notification app is running in the background on the smartphone 100A. .

The notification app may be downloaded and installed on the smartphone 100A by user A through an app download service such as the App Store provided by Apple or Google Play provided by Google, or it may be installed on the smartphone 100A etc. before the smartphone 100A etc. is sold. The software may be pre-installed by the smartphone manufacturer or communication carrier.

Note that this assumption is just an example, and includes, for example, a case where one user A owns the smartphones 100A and 100B. In other words, it should be noted that if user A owns smartphones 100A and 100B and forgets smartphone 100A somewhere, it is not excluded that the user A may send a notification to his own smartphone 100B.

The communication means 110A typically performs communications normally performed in the smartphone 100A, such as phone calls and Internet communications. Furthermore, the communication means 110A transmits the aforementioned various information inputted by the user A to the server device 200, and receives information regarding the misplacement of the smartphone 100B transmitted from the server device 200. .

The notification application can also be provided with a chat function using voice information or text information that can be performed between the smartphones 100A and 100B, a so-called monitoring function. When provided with these functions, the communication means 110A communicates chat audio information between the smartphones 100A and 100B, and transmits information such as the number of steps taken by user B using the acceleration sensor 150B to the smartphone 100A. Communication such as sending can also be performed.

Furthermore, the communication means 110A can receive an advertisement transmitted from the advertising terminal 300 when the notification application icon is tapped on the smartphone 100A to perform foreground processing, and as a result, the smartphone 100A can receive an advertisement transmitted from the advertising terminal 300 through the display image of the notification application. It can also be displayed on the display.

Although the various information mentioned above is not limited to these, typically the names of users A and B, each address, each phone number, each email address, and the information required at the time of starting the foreground processing of the notification application. Examples include user A's user ID and password.

The display means 120A displays an input screen or a confirmation screen for the above-mentioned various information received by the communication means 110A on the display of the main body of the smartphone 100A. Furthermore, the display means 120A receives advertisements distributed from the advertising terminal 300 as appropriate and displays them on the display. An example of a display image displayed by the display means 120A will be described later using FIG. 3.

The reception means 130A receives various information input by the user A according to the input image of the various information displayed by the display means 120A. The various information received by the reception means 130A is transmitted to the server device 200 by the communication means 110A, but may also be stored in the storage medium 140A.

The storage medium 140A stores, for example, various information received by the reception means 130A and a measurement log of the acceleration sensor 150A together with date and time information. In addition, the storage medium 140A may contain, for example, the destination information of the chat partner (user B's user ID of the notification application, etc.) and/or a chat log when the above-mentioned chat function is provided, and, for example, when the above-mentioned monitoring function is provided. It stores the number of steps taken by user B using the acceleration sensor 150B, the walking route taken by the user B using the GPS function of the smartphone 100B, and communication logs such as the usage history of the smartphone 100B.

The acceleration sensor 150A measures the acceleration of the main body of the smartphone 100A in three axial directions, such as the X-axis direction, the Y-axis direction, and the Z-axis direction, for example. Acceleration sensor 150A is used to measure the number of steps of user A who is carrying smartphone 100A. In this embodiment, the amount of change in the measurement result of the vertically downward acceleration by the acceleration sensor 150 is used to detect falling of the smartphone 100A and furthermore, detecting whether the smartphone 100A is left behind.

The comparison means 160A compares the amount of change in vertical downward acceleration measured by the acceleration sensor 150A over a predetermined time with a first threshold value and/or a second threshold value (first threshold>second threshold). It is something to do. What the comparing means 160A is intended to accomplish is as follows.

For example, assume that user A drops the smartphone 100A that was in his pants pocket or bag somewhere. In this case, the downward vertical acceleration of the smartphone 100A, which was approximately 1G, suddenly becomes approximately 0G, collides with the ground and the G momentarily increases depending on the hardness of the surface, and then comes to rest. Since it returns to approximately 1G, the measurement result of the acceleration sensor 150A changes accordingly. Therefore, in such a case, it is assumed that the smartphone 100A has been dropped, and the user A is notified of this fact.

Specifically, for example, it is considered that the user A is likely to drop the smartphone 100A in many cases when sitting on a chair or standing up from a chair. The seat height of fixed chairs is often set between 40cm and 42cm, while movable chairs are often adjustable between 37cm and 43cm.

Therefore, in this embodiment, in order to reliably detect that the smartphone 100A has fallen, for example, the approximate time required for the smartphone 100A to freely fall from a height of about 20 cm and reach the floor etc. is 0.00. For a period of 2 seconds or more, the vertical downward acceleration, which had been approximately 1G, became approximately 0G, and in addition, if there was a large instantaneous change in acceleration after that, then it became approximately 1G. If this is detected, it is assumed that the smartphone 100A has fallen, and this is notified to a person around the smartphone 100A or to the user B via the server device 200, for example.

Further, for example, assume that user A has forgotten the smartphone 100A somewhere. In this case, the measurement results of the acceleration sensor 150A do not change for a certain period of time. Therefore, in this embodiment, if there is no change in the vertically downward measurement result by the acceleration sensor 150A for 10 minutes, for example, it is assumed that the smartphone 100A may have been left behind, and User B is notified via a person nearby or the server device 200.

In order to realize this, the comparison means 160A calculates (1) the amount of change in the downward direction in the vertical direction over a predetermined period of time (for example, 0.2 seconds) among the accelerations in the three axial directions measured by the acceleration sensor 150A; and a first threshold value (for example, 0.9G), and/or (2) the amount of change in the downward direction in the vertical direction over a predetermined period of time (for example, 10 minutes) and the second threshold value (for example, 0.1G). Contrast.

Note that the amount of change in the acceleration measured by the acceleration sensor 150A that is compared by the comparing means 160A is not limited to these, but may be, for example, the amount of change in any one of the accelerations in the three axial directions. However, it may be the total amount of change in acceleration in the three axial directions, or it may be other than these.

The notification means 170A determines that, as a result of the comparison by the comparison means 160A, the amount of change in the acceleration of the smartphone 100A is greater than or equal to a first threshold value or less than a second threshold value, and that the smartphone 100A is determined to have been dropped or left behind. This notification is sent from the smartphone 100B to the user B and the like via the server device 200. Furthermore, the notification means 170A receives, via the server device 200, a notification that the smartphone 100B is determined to have been left behind when the amount of change in the acceleration of the smartphone 100B is less than or equal to the second threshold as a result of the comparison by the comparison means 160B. This notification is sent from the smartphone 100A to the user A and the like.

The notification means 170A may, for example, output a notification sound from the speaker of the smartphone 100A, and/or output a notification sound from the display of the smartphone 100A or from a light source such as a light for illumination mainly when capturing an image, but is not limited thereto. It is sufficient to notify that the smartphone 100A has been dropped by outputting light.

As an example, in the present embodiment, when the amount of change in the acceleration of the smartphone 100A over a predetermined period of time becomes less than or equal to the second threshold, the notification means 170A may ask, "Have you left your smartphone behind?" The notification is made by asking the user A a question by outputting audio from the speaker of the smartphone 100A.

Note that the notification means 170A prepares a plurality of notification patterns, and selects the pattern for the first notification (for example, outputting an alert sound at a low volume and/or lighting the display with a low amount of light); The pattern for the second notification (for example, outputting an alert sound at a medium volume and/or lighting the display at a medium brightness), ..., the pattern for the Nth notification (for example, outputting an alert sound at a medium volume and/or lighting the display with a medium brightness), etc. (such as outputting a sound of about 2000Hz to 5000Hz, flashing the display with a large amount of light, and notifying the smartphone 100B) can also be made different.

In this case, even if user A is seated and has left the smartphone 100A on the table for, say, 10 minutes, but has not left it behind, the "first notification" will be made. What is necessary is to operate the smartphone 100A to stop outputting the alert sound, etc. Note that when there is a response from user A in this way, the next notification will be the "first notification."

On the other hand, if user A had actually left the smartphone 100A behind, there would be no response from user A to the "first notification", so this should be communicated to the people around user A and the smartphone 100A. It is possible to make a "second notification" in a manner that makes it easier for the person who is present to notice the situation, and thereafter, unless there is a response from user A etc., the "Nth notification" will be made, and after that, for example, the "first notification" will be made. You can return to "Notification".

In addition, in the above example, the n-th notification and the n+1-th notification are different in a manner that makes it easier for user A and other people around the smartphone 100A to notice that the smartphone 100A has been left behind. There's no need to do that. Typically, for example, when the battery level is low, a power-saving notification may be sufficient, such as the n+1th notification at a lower volume than the nth notification.

Moreover, when the above-mentioned monitoring function is provided, it may be possible to notify not only that the smartphone 100A has been dropped, but also that the user A has fallen, using the same method. In other words, for example, when user A falls down with the smartphone 100A in his pants pocket or bag, the acceleration sensor 150A of the smartphone 100A detects that the vertical downward acceleration is approximately 0 G for 0.2 seconds or more. Detected. In that case, for example, if user A is an elderly person, this is preferable because it will trigger help from those around him, and furthermore, it is possible to notify user B that user A has dropped or fallen the smartphone 100A.

The control means 180A controls execution of notification by the notification means 170A based on the measurement log of the acceleration sensor stored together with date and time information in the storage medium 140A. What is intended to be achieved by the control means 180A is as follows.

For example, if user A is watching a TV program, reading, or working while placing the smartphone 100A on a table etc., even though the smartphone 100A has not been left behind. First, the amount of change in the acceleration of the smartphone 100A over a predetermined period of time becomes less than or equal to the second threshold. In this case, it is not desirable to make unnecessary notifications, so the purpose is to avoid this.

For this purpose, the user A is made to input basic lifestyle patterns as the various information described above in advance and stored in the storage medium 140A. Alternatively, or in addition to this, as a result of the notification as in the above notification example, a response from user A indicating that "I have not left anything behind" or, going a step further, a response indicating that "I am at work" may be received. If there is, the smartphone 100A accepts the response and stores it in the storage medium 140A.

In this way, in the smartphone 100A, even if the amount of change in the acceleration of the smartphone 100A in a predetermined time becomes equal to or less than the second threshold, the control means 180A refers to the storage medium 140A and prevents the notification means 170A from executing the notification. It becomes possible to decide whether or not to do so. As a result, the smartphone 100A does not ask user A any unnecessary questions.

Further, in order to avoid bothering user A, for example, the response from user A and the measurement log are transmitted to the server device 200 through the communication means 110A, and the server device 200 transfers these to user A's learning data. One method is to perform learning using an artificial intelligence device, send the learning results back to the smartphone 100A, and store them in the storage medium 140A.

Note that the response by the user A may be, for example, by pressing a button provided on the smartphone 100A, or by pressing a predetermined position displayed on the display (for example, "I did not leave it behind" or "I am at work", etc.) This can be accepted by tapping the display part (displayed part showing "I have not left anything behind") or by turning on the microphone and capturing the utterances uttered by the user A such as "I have not left anything behind" and analyzing the voice.

FIG. 3 is a diagram showing an example of an image when inputting various information displayed on the display of the smartphone 100A by the display means 120A of FIG. 2. FIG. 3 shows an example of an input image after setting login information for using the notification application.

FIG. 3(a) shows a screen example of input columns for various information of user A himself. Here, for example, user A's name, address, telephone number, and e-mail address are input. Various information input by the user is accepted by the receiving means 130A.

FIG. 3B is a diagram illustrating an example of a screen for inputting various information about user B who wants to contact the user when the user A has left behind the smartphone 100A. The screen example shown in FIG. 3(b) transitions after inputting various information into the input fields shown in FIG. 3(a).

In this example, in addition to user B's name, address, telephone number, and e-mail address, user B's user ID for the notification application is input. Various information input by the user is accepted by the receiving means 130A.

Thereafter, various information input into the input fields shown in FIGS. 3(a) and 3(b) are transmitted to the server device 200 by the communication means 110A, as described above. In the server device 200, when various information transmitted from the smartphone 100A is input, the information is registered in a database (not shown).

Thereby, even if user A forgets smartphone 100A somewhere, it is possible to notify user B using server device 200.

FIG. 4 is a diagram showing an example of storage of basic lifestyle pattern information of each user stored in a database attached to the server device 200 of FIG. In this embodiment, the lifestyle pattern information of each user is also stored in the storage medium 140A, but the storage location may be only the database or only the storage medium 140A.

Figure 4 shows a state in which the user name, wake-up time, departure time, work/class time, break time, return time, and bedtime of each user are stored as a set. There is. For example, user A's wake-up time is "6:00," departure time is "7:00," work/class time is "8:30-15:30," and break time is "11:45-12." :45'', return time is ``16:00'', and bedtime is ``22:00''.

Therefore, for user A, for example, the change in acceleration of the smartphone 100A over a predetermined period of time, excluding the time period "11:45-12:45" from the time period "8:30-15:30" Even if the amount is less than the second threshold value, the control means 180A can refer to the storage medium 140A and not execute the notification by the notification means 170A.

FIG. 5 is a diagram showing an example screen of a message notifying user B that user A has left behind smartphone 100A. For example, on the smartphone 100B, there is a message saying, ``User A seems to have left the device at the following location 10 minutes ago,'' and the location of the left-behind location is, for example, ``Near 3-4-3 Kasumigaseki, Chiyoda-ku, Tokyo.'' ” text information and a map corresponding to the location are displayed. Further, in FIG. 5, an advertisement publication area 510 in which an advertisement distributed from the advertisement terminal 300 is posted is also provided.

According to this notification mode, if it is reported that the location is user A's home, it also has a function to watch over user A, since user A may have fallen down. It turns out that.

Note that the message shown in FIG. 5 can be sent through the email address of user B accepted by the reception means 130A, but in addition to or in place of this, the message can be sent through the URL assigned to the web page of user A's own SNS. It is also possible to accept this information by the receiving means 130A and notify the user A's acquaintances through the SNS.

Further, the service provider of the mobile terminal system of this embodiment may prepare a notification web page so that the user A can log in and specify the location where the user A has left his/her smartphone 100A.

As explained above, according to the mobile terminal system of this embodiment, when user A drops the smartphone 100A, it is possible to immediately notify the user A of this, and the user A can drop the smartphone 100A. If the user A forgets the item somewhere, or if the user A collapses at home or the like, the user B can be notified of this fact.
