<Structure example of a communication system including a mobile terminal according to an embodiment of the present invention>
FIG. 1 shows a configuration example of a communication system including a mobile terminal according to an embodiment of the present invention.

The communication system includes a mobile terminal 10, a content server 20, and a communication control server 30.

An application program (hereinafter, referred to as a walking smartphone deterrent application) for deterring a user's movement operation, that is, a so-called “walking smartphone”, is pre-installed on the mobile terminal 10. The walking smartphone deterrence application is started when the mobile terminal 10 is activated, and is continuously executed while the mobile terminal 10 is turned on. The walking smartphone deterrent application corresponds to the program of the present invention.

However, the movement operation in the present embodiment includes not only viewing and operating the screen while walking, but also viewing and operating the screen while driving a car, motorcycle, bicycle, or the like. ..

As the mobile terminal 10, not only smartphones but also electronic devices such as mobile phones, tablet computers, and portable game machines that can be carried by users are assumed.

The mobile terminal 10 is connected to the content server 20 and the communication control server 30 via the network N. Network N is a mutual wireless communication network such as a mobile phone communication network, a wireless LAN, and the Internet.

The content server 20 is managed by, for example, a distributor of a walking smartphone deterrent application. The content server 20 transmits the question-type content reproduced on the mobile terminal 10 to the mobile terminal 10 via the network N.

The communication control server 30 is managed by, for example, a telecommunications carrier. The communication control server 30 controls a call by the mobile terminal 10 via the network N. Further, the communication control server 30 controls the data communication of the mobile terminal 10 via the network N. Specifically, for example, the communication band is limited or the limited communication band is released according to the amount of data communication.

Next, FIG. 2 shows a configuration example of a functional block of the mobile terminal 10.

The mobile terminal 10 includes a processing unit 11, a storage unit 12, an imaging unit 13, a sensor unit 14, a communication unit 15, an input unit 16, and a display unit 17.

The processing unit 11 includes, for example, a CPU (Central Processing Unit) included in a smartphone or the like, and controls the entire mobile terminal 10 in an integrated manner. Further, the processing unit 11 realizes the movement operation detection unit 111, the condition setting unit 112, the restriction unit 113, and the content reproduction unit 114 by executing the walking smartphone suppression application pre-installed in the mobile terminal 10.

The movement operation detection unit 111 detects the movement operation and movement stop of the user based on the outputs of the imaging unit 13, the sensor unit 14, and the input unit 16, and measures the movement operation time and the movement stop time. As for the method of detecting the movement operation and the movement stop of the user by the movement operation detection unit 111, the existing technology can be appropriately adopted.

The condition setting unit 112 sets the first threshold value, the second threshold value, and the number of questions, which will be described later, based on the condition information 121 and the history information 122 recorded in the storage unit 12.

When the movement operation of the user is detected by the movement operation detection unit 111, the restriction unit 113 alerts the user to stop the movement operation. Specifically, for example, the message "Walking smartphone is dangerous!" Is superimposed on the current display screen (for example, the screen of e-mail, message, game, SNS (Social Network System), etc.) to call attention. indicate.

Further, the limiting unit 113 limits the user's use of the mobile terminal 10 when the duration of the moving operation exceeds the first threshold value. Specifically, for example, the current display screen is erased or another image is superimposed and displayed so that the user cannot visually recognize and operate the current display screen. However, even while the user's use is restricted, it is desirable not to restrict the telephone function in consideration of the occurrence of an emergency.

Further, the restriction unit 113 generates and updates the history information 122 representing the history of restricting the use of the user with respect to the mobile terminal 10. The history information 122 is recorded in the storage unit 12. Further, the restriction unit 113 releases the user's usage restriction.

When the use of the content playback unit 114 is restricted and the movement stop of the user is detected by the movement operation detection unit 111, the question is transmitted from the content server 20 in advance and recorded in the storage unit 12. The type content 124 is reproduced and superimposed on the display screen.

In the reproduced question-type content 124, the questions for which the user is requested to answer are displayed as many times as the number of questions set according to the past limit number of times. The question to the user may be randomly determined, or may be determined according to the usage environment such as the date and time, the season, and the area. Further, the determination may be made based on the user attributes recorded in the user information 123 of the storage unit 12, or may be determined based on the user's past answers.

Further, the content reproduction unit 114 ends the question-type content when the user completes the answers to all the questions of the question-type content 124 and the movement stop time exceeds the second threshold value.

The storage unit 12 is composed of, for example, a semiconductor memory included in a smartphone or the like, and is used as a work area of the processing unit 11 or a storage area for various information. The storage unit 12 stores condition information 121, history information 122, user information 123, and question-type content 124.

FIG. 3 shows an example of condition information 121. In the condition information 121, the first threshold value, the second threshold value, the number of questions, and the reset cycle are recorded in association with the usage limit number count value obtained by counting the past usage limit number according to a predetermined rule.

The first threshold value is a value for comparison with the movement operation time of the user. The second threshold value is a value for comparison with the movement stop time of the user. The number of questions is the number of questions to the user in the reproduced question-type content 124. The reset cycle is a value representing a cycle for resetting the usage limit number of times count value recorded in the history information 122 to 0.

The first threshold value is recorded as a smaller value as the usage limit count value is larger, the second threshold value is recorded as a larger value as the usage limit count value is larger, and the question count is recorded as a larger value as the usage limit count value is larger. There is. As for the reset cycle, one day is recorded when the usage limit count value is 0 to 2 times, and ∞ (meaning that the reset is not performed) is recorded when the usage limit count value is 3 times or more.

In the example of the figure, for example, when the usage limit count value is 0, the first threshold is 10 seconds, the second threshold is 5 seconds, the number of questions is 1, and the reset cycle is 1 day. Further, for example, when the usage limit count value is 1, the first threshold is 9 seconds, the second threshold is 10 seconds, the number of questions is 2, and the reset cycle is 1 day.

FIG. 4 shows an example of the history information 122. The history information 122 is generated and updated by the restriction unit 113. The history information 122 includes a usage limit count value, a reset date and time, a date and time of the usage restriction performed in the past, a question ID representing a question in the question-type content 124 played at the time of the usage restriction, and a user for the question. The answer is recorded. The usage limit count value is a value obtained by counting the number of data recorded in the history information 122, that is, the number of usage restrictions performed in the past according to a predetermined rule. The reset date and time is the date and time when the usage limit count value was last reset.

Return to FIG. The user information 123 records user attribute information (age, gender, residential area, language used, occupation, etc.). The user information 123 is referred to when determining a question in the reproduced question-type content 124. The question-type content 124 is transmitted by the content server 20 in advance and received by the communication unit 15.

The image pickup unit 13 includes, for example, a camera unit included in a smartphone or the like, captures the user's face when the user's movement operation is detected, and outputs the captured image to the movement operation detection unit 111. The image of the user's face is used for detecting the line of sight of the user, which is one of the criteria for detecting the movement operation.

The sensor unit 14 is composed of various sensor units such as a proximity sensor, an acceleration sensor, a gyro sensor, and a GPS (Global Positioning System) sensor included in a smartphone or the like, and when a user's movement operation is detected, each sensing result is transmitted to the movement operation detection unit. Output to 111.

The communication unit 15 includes, for example, a communication module included in a smartphone or the like, and communicates with the content server 20 or the like via the network N. The input unit 16 is composed of, for example, a touch panel or the like laminated on a display of a smartphone or the like, and receives a user's operation and outputs it to the processing unit 11. The display unit 17 is composed of a display provided on, for example, a smartphone or the like, and displays various screens.

<Restrict history reset processing by mobile terminal 10>
Next, the restriction history reset process by the mobile terminal 10 will be described.

FIG. 5 is a flowchart illustrating an example of the restriction history reset process. The restriction history reset process is continuously executed while the power of the mobile terminal 10 is turned on.

First, the limiting unit 113 acquires the current time and determines whether or not the predetermined time (for example, 0:00:00 AM) has been reached (step S1). When the limiting unit 113 determines that the current time has not reached the predetermined time (NO in step S1), the limiting unit 113 continues to acquire the current time until the current time reaches the predetermined time.

After that, when the limiting unit 113 determines that the current time has reached a predetermined time (YES in step S1), the reset cycle is specified by referring to the condition information 121 and the history information 122 recorded in the storage unit 12 (YES in step S1). Step S2).

Specifically, the limiting unit 113 reads out the usage limit count value recorded in the history information 122, refers to the condition information 121, and specifies the reset cycle corresponding to the usage limit count value. For example, when the usage limit count value is 2, one day is specified as the reset cycle corresponding to the usage limit of 2 from the condition information 121.

Next, the limiting unit 113 resets the usage limit number count value recorded in the history information 122 to 0 according to the reset cycle specified in step S2 (step S3). Specifically, the usage limit count value is reset to 0 only when the time from the reset date and time recorded in the history information 122 to the current date and time is equal to or longer than the reset cycle. On the contrary, if the time from the reset date and time recorded in the history information 122 to the current date and time is less than the reset cycle, the usage limit count value is not reset.

After step S3, the process returns to step S1, and the processes after step S1 are repeated.

According to the limit history reset process described above, the usage limit count count value of the history information 122 can be reset to 0. However, when the usage limit count value is 3 times or more, the usage limit count value is not reset, so that the usage restriction can be performed more strictly for the user who has become habitual in walking operation.

However, as a remedy for such a user, for example, when the average usage limit number of times per day in the past month is less than or equal to a predetermined number, the usage limit number count value is reset to 0. You may try to do it.

<Usage restriction processing by mobile terminal 10>
Next, the usage restriction processing by the mobile terminal 10 will be described.

FIG. 6 is a flowchart illustrating an example of use restriction processing. FIG. 7 shows a display example of a screen for explaining the usage restriction process.

The usage restriction process is continuously executed while the power of the mobile terminal 10 is turned on.

First, the movement operation detection unit 111 starts detecting the movement operation (including movement stop) of the user based on the outputs of the imaging unit 13, the sensor unit 14, and the input unit 16 (step S11). Next, the movement operation detection unit 111 determines whether or not the user is in the movement operation (step S12). Specifically, for example, the sensor unit 14 detects the movement of the mobile terminal 10, and the image captured by the imaging unit 13 detects that the user is looking at the screen, and the input unit 16 detects that the user is looking at the screen. If at least one of the inputs of is detected, it is determined that the user is in the process of moving.

Here, when the movement operation detection unit 111 determines that the user is not in the movement operation (NO in step S12), the movement operation detection unit 111 continues to detect the user's movement operation.

On the contrary, when the movement operation detection unit 111 determines that the user is in the movement operation (YES in step S12), the condition setting unit 112 then determines the condition information 121 and the history recorded in the storage unit 12. Various conditions are set based on the information 122 (step S13).

Specifically, the usage limit count value is read from the history information 122, and the first threshold value, the second threshold value, and the question count corresponding to the usage limit count value are read from the condition information 121, and the first threshold value and the question count are read. The second threshold value is set in the limiting unit 113, and the number of questions is set in the content reproduction unit 114.

Next, the limiting unit 113 calls attention to the user who is in the process of moving (step S14). Specifically, for example, on the current display screen (game screen in the example of the figure) 161 as shown in FIG. 7 (A), as shown in FIG. 7 (B), a warning message (example of the figure). Then, "Walking smartphone is dangerous!") 162 is displayed transparently. In addition, instead of or in addition to the alert message 162, the alert may be issued by voice or vibration.

Next, the movement operation detection unit 111 resets the movement operation time to 0 and then starts the time counting (step S15), and determines whether or not the movement operation time exceeds the first threshold value (step S16). Here, when the movement operation detection unit 111 determines that the movement operation time does not exceed the first threshold value (NO in step S16), the movement operation detection unit 111 then determines that the user's movement operation is continuing. It is determined whether or not there is (step S17).

Here, when the movement operation detection unit 111 determines that the movement operation of the user is continuing (YES in step S17), the process is returned to step S16, and steps S16 and S17 are repeated. On the contrary, when the movement operation detection unit 111 determines that the movement operation of the user is not continuing (the user has stopped the movement operation) (NO in step S17), the process is returned to step S12.

When the user continues the movement operation and the movement operation detection unit 111 determines that the movement operation time exceeds the first threshold value (YES in step S16), the restriction unit 113 then limits the use of the user. , Update the history information 122 (step S18).

Specifically, the restriction unit 113 erases the warning message 162, and for example, as shown in FIG. 7 (C), a warning message indicating that the use is being restricted (in the example of the figure, "use is restricted". ”) 163 is superimposed and displayed so as to cover the entire display screen 161 and the user's operation input is invalidated. In addition to the warning message 163, it may be notified by voice or vibration that the use is being restricted.

Further, the restriction unit 113 updates the history information 122 by adding the current date and time when the usage restriction is applied to the history information 122 and adding 1 to the usage restriction number count value.

Next, the movement operation detection unit 111 determines whether or not the movement of the user has stopped (step S19). Here, when the movement operation detection unit 111 determines that the movement of the user has not stopped (NO in step S19), the process is returned to step S18. That is, the usage restriction for the user is continued.

On the contrary, when it is determined that the movement of the user has stopped (YES in step S19), the movement operation detection unit 111 resets the movement stop time to 0 and then starts the timing (step S20). ..

Next, the content reproduction unit 114 reads out the question-type content 124 recorded in the storage unit 12 and starts reproduction (step S21). In the reproduced question-type content 124, questions 164 in the form of presenting options to the user are sequentially displayed as many times as the number of questions set in step S13, for example, as shown in FIG. 7 (D). The user's operation input to the reproduced question-type content 124 is valid, and the user can answer each question by selecting an option. The question ID representing the question in the reproduced question-type content 124 and the user's answer to the question are output from the content reproduction unit 114 to the restriction unit 113, and are added to the history information 122 of the storage unit 12 by the restriction unit 113. Will be done.

Next, the content reproduction unit 114 determines whether or not the user has already answered all the questions to be displayed in sequence (step S22). Here, when the content reproduction unit 114 determines that the user has not answered all the questions, that is, there are still unanswered questions (NO in step S22), then the movement operation detection unit 111 determines whether or not the user's movement stop is continuing (step S23).

Here, when the movement operation detection unit 111 determines that the movement stop of the user is not ongoing, that is, the user has resumed the movement (NO in step S23), the content reproduction unit 114 then asks the question type. Playback of the content 124 is finished (step S26). After this, the process returns to step S18. That is, the user's use is restricted again.

On the contrary, when the movement operation detection unit 111 determines that the movement stop of the user is continuing (YES in step S23), the process is returned to step S22, and steps S22 and subsequent steps are repeated. After that, when the content reproduction unit 114 determines that the user has answered all the questions (YES in step S22), the movement operation detection unit 111 then exceeds the second threshold value for the movement stop time. It is determined whether or not the content is present (step S24). Here, when the movement operation detection unit 111 determines that the movement stop time does not exceed the second threshold value (NO in step S24), the process proceeds to step S23 again.

On the contrary, when the movement operation detection unit 111 determines that the movement stop time exceeds the second threshold value (YES in step S24), the content reproduction unit 114 then ends the reproduction of the question-type content 124. , The restriction unit 113 releases the usage restriction on the user (step S25). After that, the process is returned to step S12, and steps S12 and subsequent steps are repeated.

According to the usage restriction process described above, when a movement operation by the user is detected, the user can be alerted. Further, when the user continues the movement operation and the movement operation time exceeds the first threshold value despite the alert being issued, the use of the user can be restricted. Then, when the user stops moving, the question-type content is played, and when the user answers all the questions and the movement stop time exceeds the second threshold value, the user's usage restriction is released. Can be done. If there are unanswered questions or if the user's movement resumes, the usage restrictions can be continued. As a result, the user's movement operation can be suppressed.

<Modification example>
In the above-mentioned usage restriction processing, when the user answers all the questions and the movement stop time exceeds the second threshold value, the user's usage restriction is released. If the user accepts donations or charges for disasters, the usage restrictions may be lifted.

As a usage restriction for the user, for example, the communication band of data via the network N may be limited. The communication band may be limited by the limiting unit 113 controlling the communication unit 15 or by coordinating with the communication control server 30 and causing the communication control server 30 to limit the communication band.

<About question-type content>
Question-type content that is played while the usage is restricted can be used as, for example, a public service announcement or a corporate advertisement. Specifically, for example, a telecommunications carrier that sells smartphones pre-installed with a walking smartphone deterrence application solicits advertisers (administration, companies, etc.) and discounts or points a part of the collected advertising fees. It may be returned to the user as such. As a result, all advertisers such as users and telecommunications carriers can obtain merits.

The following examples are assumed as public service announcements.
・ Advertisement that warns of walking smartphones For example, "1000 walking smartphone accidents this year, who is the next perpetrator?"
For example, "If you injure a passerby with a walking smartphone, you will be guilty of negligent injury, a fine of 300,000 yen or a fine. Did you know?"
・ Advertisement for information on wanted criminals and fugitives For example, if you get an answer of "YES" to this advertisement, "Do you remember this face?", Call the police 110 by telephone function. You may do so.
・ Advertisement that promotes election voting For example, if you get a "NO" answer to this advertisement, such as "Did you go to vote?", You can start the map application and display the location of the polling place. Good.
