  First, the controller 10 determines whether the screen is being displayed as step S12. That is, it is determined whether an image is being displayed on the display 2A. When it is determined that the screen is not being displayed (No in step S12), the controller 10 returns to the process in step S12. When it is determined that the screen is being displayed (Yes in step S12), the controller 10 acquires the detection result of the sensor as step S14. Specifically, the controller 10 acquires at least one detection result of the acceleration sensor 15, the magnetic sensor 18, and the gyroscope 17 and at least one detection result of the communication unit 6 and the GPS receiver 24. At least one detection result of the acceleration sensor 15, the magnetic sensor 18, and the gyroscope 17 is used for determination of the movement state and for determination of whether or not the user is walking. At least one detection result of the communication unit 6 and the GPS receiver 24 is used to determine whether or not the user carrying the smartphone 1 is in a predetermined area.

  After acquiring the detection result of the sensor, the controller 10 determines whether the user is walking as step S16. Specifically, the controller 10 compares the detection result (first information) of the acceleration sensor 15, the magnetic sensor 18, and the gyroscope 17 with the moving state data 9C, and based on the comparison result, is the user walking? Determine. Here, the state where the user is not walking is a state where the user is stopped and other moving means, for example, a state where the user is moving on a bicycle, motorcycle, automobile, train, amphibious vehicle, ship and airplane. including. The state in which the user is walking includes various cases where the movement method is movement by the user's foot.

The movement by the user's feet includes at least one of walking, that is, walking and running, that is, running. Further, the movement by the user's foot includes a state where the user's foot is stopped without moving. The movement by the user's foot includes that the user walks using a cane or a wheelbarrow.

  If the controller 10 determines that the user is not walking (No in step S16), the controller 10 returns to step S12. When it is determined that the user is walking (Yes in Step S16), the controller 10 determines whether the user is in the intersection area as Step S18. The controller 10 of an embodiment determines whether communication with the roadside device 104 has been established based on the information (second information) acquired from the communication unit 6 and the situation determination data 9B. If the controller 10 determines that communication with the roadside device 104 has been established, the controller 10 determines that the user is in the intersection area. That is, the controller 10 uses the predetermined area 120 as an intersection area, and the user is in the predetermined area 120 that is an area around the intersection 109 including the intersection 109 based on a state of communication with the roadside device 104. judge.

  An example of the process will be described more specifically with reference to FIG. In step S32, the controller 10 detects a device capable of short-range wireless communication based on the detection result of the sensor. A communicable device is a communication device in a range where a signal capable of transmitting and receiving data arrives. When the controller 10 detects a communicable device, the controller 10 determines whether communication with the roadside device 104 is possible in step S34. When it determines with the controller 10 being communicable with a roadside machine (it is Yes at step S34), it determines with it being in an intersection area | region as step S36. When it is determined that the controller 10 cannot communicate with the roadside machine (No in Step S34), the controller 10 determines that the vehicle is not in the intersection area as Step S38. With the above processing, the controller 10 uses the communication unit 6 as a sensor, specifies the positional relationship with the roadside unit 104 based on the communication result of the communication unit 6, and determines whether the vehicle is in the intersection area.

  When it is determined that the controller 10 is not in the intersection area (No in step S18), the controller 10 displays the first screen as step S19. The first screen is a screen that is layered on a screen that displays an image with a transparent background including the message “Walking smartphone”. When it is determined that the controller 10 is in the intersection area (Yes in Step S18), the second screen is displayed as Step S20, and the housing 20 is vibrated by the vibrator 22 as Step S22. The second screen is a screen that is layered on a screen that displays an image with a transparent background including a message “Please pay attention to the surroundings”.

  As described above, when the smartphone 1 detects a walk, the smartphone 1 changes the notification method depending on whether or not it is in an intersection area (predetermined area). Notification can be performed in a manner that is easy to communicate to the user. Thereby, since the notification method can be changed corresponding to the necessity of notification, it is possible to notify the user with a more appropriate load. Thereby, the user can make it easy to use the function of paying attention to the use of the smartphone 1 while walking, and can appropriately know the state that requires more attention.

  Moreover, when the user is in the intersection area, the smartphone 1 according to an embodiment can make the smartphone 1 difficult to use by vibrating the housing with a vibrator. Use of the screen display can be suppressed.

  In addition, when the user is in the intersection area and the user is walking, the smartphone 1 may notify the user by a method other than the vibration of the vibrator 22. As a notification method, a warning sound and a warning message may be output from the speaker 11, or the light emitting unit 23 may emit light and be notified by light. By notifying with sound or light, it can be notified that the smartphone 1 is being used in the vicinity, and an environment in which the user can easily stop using the smartphone 1 can be created.

  In the process shown in FIG. 6, when the screen is being displayed, the detection result of the sensor is acquired. However, acquisition of data used for determining whether or not walking and data used for determining the surrounding situation are However, it may always be performed, or may be executed by a process different from the process shown in FIG. In addition, if the controller 10 can switch the process to be executed based on the situation when the user is walking, the order of determining whether the user is walking and whether the user is in the intersection area may be reversed. Good.

  Moreover, in the said embodiment, when the user is walking, the message displayed is changed depending on whether the user is in the intersection area or not, but the message may be the same.

  Moreover, the smart phone 1 may alert | report by the method transmitted by a user, when the situation where danger level is still higher is detected according to the surrounding situation when a user exists in an intersection area | region. FIG. 8 is a flowchart illustrating an example of control performed by the smartphone according to one embodiment. The process of FIG. 8 may be applied to the process of FIG. Hereinafter, points peculiar to the processing of FIG. 8 will be described.

  The controller 10 determines that the user is walking in step S16, and determines that the user is in the intersection area in step S18. And the controller 10 displays a 2nd screen, and after vibrating with a vibrator, it determines whether there exists a vehicle which approaches a user as step S42. When the controller 10 acquires information (third information) from the roadside device 104 via the communication unit 6 and acquires information indicating that the vehicle 102 with which the roadside device 104 can communicate exists, the vehicle approaching the user Judge that there is. When it is determined that there is no vehicle approaching the user (No in step S42), the controller 10 ends this process. When it is determined that there is a vehicle approaching the user (Yes in step S42), the controller 10 outputs a sound from the speaker 11 as step S44. The sound output from the speaker 11 may be a warning sound or a warning message.

  The controller 10 determines that the user is walking, determines that the user is in the intersection area, and, when there is a vehicle approaching the user, performs notification by three means of sound in addition to display and vibration Thus, the user can be notified that the state needs attention. Thereby, the smart phone 1 can perform more appropriately according to a condition, when displaying a screen, while a user walks.

  In addition, when the smartphone 1 determines that the user is walking, determines that the user is in the intersection area, and there is a vehicle approaching the user, the smartphone 1 is different from the first screen and the second screen, respectively. A screen may be displayed. As the third screen, for example, there is a message “Danger of collision”.

  In addition, the smartphone 1 determines that the user is walking, determines that the user is in the intersection area, and restricts the operation on the screen when there is a vehicle approaching the user. Or the smart phone 1 restrict | limits operation with respect to a screen, when it determines with the user walking and it determines with the user being in an intersection area | region. If the smartphone 1 determines that the user is walking and determines that the user is not in the intersection area, the smartphone 1 may validate the operation on the screen. Alternatively, the smartphone 1 may determine that the user is walking and validate the operation on the screen when there is no vehicle approaching the user. Thereby, the user can concentrate on operation of the smart phone 1 by restrict | limiting operation with respect to a screen, and can suppress delaying to the response | compatibility to the surrounding condition change.

  In addition, the smart phone 1 of an embodiment uses the notification unit when it is determined that the user is walking, the user is determined to be in the intersection area, and whether there is a vehicle approaching the user. Although the notification is executed, the notification using the notification unit may be executed when it is determined that the user is walking and it is determined whether there is a vehicle approaching the user. As described above, even when the user is not in the predetermined area, it is possible to appropriately notify the user of necessary information by notifying the notification unit when there is a vehicle approaching the user. In addition, the smartphone 1 and the communication unit may directly communicate with the vehicle 102 to detect whether the vehicle is approaching according to the result of the direct communication.

  In the said embodiment, although the object with which the smart phone 1 communicates was made into the roadside machine 104, and made the area | region of object into the intersection, it is not limited to this. The smartphone 1 receives a GPS satellite information by the GPS receiver 24 as a situation detection unit that acquires surrounding information in addition to or in place of the communication unit 6, specifies the current position information, In this case, a road with a high degree of risk is set in advance as a predetermined area, and it is possible to determine that the road is in the predetermined area when walking on a road with a high degree of risk. The smartphone 1 may specify current position information by using a receiver of radio signals from positioning artificial satellites other than GPS satellites as a situation detection unit that acquires surrounding information.

  Moreover, in the said embodiment, although the predetermined area | region was made into the intersection area | region, it is not limited to this.
