It is a flowchart which shows the procedure of the control method of the portable device which concerns on an Example.

  The embodiment of the present invention is easy to operate when a user of a mobile device such as a mobile phone terminal or a smartphone is driving a vehicle, and at least some of the functions provided by the mobile device are limited. We propose a technology that improves both the safety and the convenience of the user when using a portable device by providing a user interface for the driver. The portable device determines whether or not the user is driving the vehicle based on a plurality of determination criteria. In particular, it is determined whether or not the user is a driver of the vehicle and whether or not the user is using the portable device by holding it. As a result, it is possible to more accurately determine whether or not it is a dangerous use situation, so it is possible to reduce the situation where the function is restricted until it is not necessary to restrict the function. Convenience can be improved. In addition, since the user interface can be switched appropriately and the use of mobile devices can be restricted while driving the vehicle, safety when using the mobile device is improved, and traffic accidents and traffic caused by the use of the mobile device are improved. The frequency of legal violations can be reduced.

  FIG. 1 is a diagram for explaining the relationship between the state of a mobile device and usage restrictions. The portable device of the present embodiment can switch the operation mode between the operation mode and the normal mode. In the driving mode, a simple user interface for the driver of the vehicle is provided, and use of at least some of the functions provided by the portable device is restricted. In the normal mode, a normal user interface is provided and functions are not limited. The portable device has a display device of the portable device turned on, the portable device is moving, the current position of the portable device is on the road, and the user of the portable device is a vehicle driver. If determined, the operation mode of the portable device is switched from the normal mode to the operation mode.

  When the display device of the portable device is turned off, it is considered that the portable device has not been operated, and thus there is no need to limit the function. Even if the display device of the portable device is turned on, if the portable device is not moving, the user of the portable device is considered not to be driving, so the function is not limited. Even if the mobile device display device is on and the mobile device is moving, if the current position of the mobile device is not on the road, the user of the mobile device can use a means other than a vehicle, such as a train. Since it is considered moving, it does not limit the functions. In addition, even when the display device of the mobile device is on and the mobile device is moving on the road, if the mobile device is not used by the driver of the vehicle, Since passengers and passengers are thought to be using mobile devices, the functions are not limited.

  When it is determined that the mobile device is fixed to the dashboard or the like in the driving mode, the user of the mobile device is operating while watching the mobile device held by the hand. Therefore, even if operation through a simple user interface is allowed, the risk does not increase so much. However, if it is determined that the mobile device is held by the user's hand in the driving mode, the driver may be operating while gazing at the mobile device held by the hand, causing an accident. It is necessary to stop the operation of the portable device. Therefore, in this embodiment, in such a case, a warning is issued to stop the operation of the mobile device, and it is determined that the mobile device is not held by the hand, such as being placed on the seat or fixed to the dashboard. Until this is done, the display device of the portable device is turned off so that the portable device cannot be operated.

  As a result, it is possible to more accurately detect a dangerous state in which the driver of the vehicle is holding and operating the portable device, and to stop the operation, thereby improving safety when using the portable device. be able to. Moreover, since the situation which restrict | limits the function of the portable apparatus which a passenger, a passenger, etc. use can be reduced, the convenience of the user of a portable apparatus can be improved. In addition, when the mobile device is fixed to a dashboard, etc., a simple user interface for the driver is provided. For example, an application such as a game in which the user watches the display of the mobile device is executed. The application that is desired to be executed during driving, such as navigation for guiding the route to the destination, can be executed. Thereby, a user's convenience can be improved.

  The conditions for canceling the operation mode and switching to the normal mode will be described later.

  FIG. 2 shows a configuration of the portable device according to the embodiment. The portable device 10 receives a camera 11 for capturing an image around the portable device 10, a sensor 12 for detecting a situation around the portable device 10 or a state of the portable device 10, and an operation input from a user. An operation unit 13 such as a touch panel or a button for receiving, a display device 40 that displays a screen of a user interface or an application executed by the mobile device 10, and a control unit that controls the operation of each component of the mobile device 10. 50 and a storage device 41 for storing programs and data used by the control unit 50.

  The control unit 50 limits an application execution unit 51 that executes an application for providing various functions to the user, and at least a part of the functions provided by the application execution unit 51 under a predetermined condition. And a function control unit 20. The function control unit 20 includes a display ON / OFF determination unit 21, a movement state determination unit 22, a position determination unit 23, a driver determination unit 24, a gripping state determination unit 25, an operation mode UI control unit 26, an application activation unit 27, and an operation. A mode UI start determination unit 28, an operation mode UI end determination unit 29, and a driver determination release determination unit 30 are provided. These functions are realized by a CPU, a memory, a program loaded in the memory, and the like, and here, a configuration realized by their cooperation is illustrated. The program may be built in the mobile device 10 or may be supplied from the outside in a form stored in a recording medium. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The display ON / OFF determination unit 21 determines ON / OFF of the display device 40. The display device 40 is automatically turned off when the operation unit 13 does not accept an operation input by the user for a predetermined time or more, and is automatically turned on when the operation unit 13 accepts an operation input by the user. Is done. The display ON / OFF determination unit 21 determines whether the display device 40 is currently ON or OFF.

  The movement state determination unit 22 determines the movement state of the mobile device 10. The movement state of the mobile device 10 may be determined based on a current position estimated based on a signal received by a GNSS (Global Navigation Satellite System (s)) receiver mounted on the mobile device 10, or mobile The determination may be made based on a detection result by a sensor 12 such as a camera, an acceleration sensor, or a gyro sensor mounted on the device 10. The movement state determination unit 22 determines that the mobile device 10 is moving when it continues to move for a predetermined time (T1) or longer. The movement state determination unit 22 determines that the mobile device 10 is moving when the mobile device 10 is moving at a speed greater than or equal to a predetermined speed, or when the mobile device 10 has moved a distance greater than or equal to a predetermined distance. Also good.

  The position determination unit 23 determines the current position of the mobile device 10. As described above, the current position of the mobile device is estimated based on signals received by the GNSS receiver, sensor values of various sensors, and the like. The position determination unit 23 refers to the estimated current position and the map information stored in the storage device 41 to determine whether or not the current position of the mobile device 10 is on the road. The position determination unit 23 may determine that the mobile device 10 is on the road when the current position of the mobile device 10 is determined to be on the road for a predetermined distance or a predetermined time or more.

  The driver determination unit 24 determines whether the user of the mobile device 10 is a vehicle driver. The driver determination unit 24 determines whether or not the user of the portable device 10 is a vehicle driver by analyzing an image captured by the camera 11.

  FIG. 3 shows an example of a user image taken by the camera 11. FIG. 3A shows a camera provided on the same side as the display device 40 of the portable device 10, that is, the side facing the user when used when the portable device 10 is fixed to the dashboard of the vehicle. 11 shows an example of an image picked up by No. 11. The captured image shows a driver who is a user and a passenger who is in the rear seat. FIG. 3B shows an example of an image captured by the camera 11 provided on the same side as the display device 40 of the mobile device 10 when the mobile device 10 is held by the user's hand. The captured image shows the driver who is the user. In the case of FIG. 3B, since the distance between the camera 11 and the user's head is closer than in the case of FIG. 3A, the user's head is shown larger. FIG.3 (c) shows the example of direction of a user's eyes | visual_axis. When the user is gazing at the display device 40, the user's line of sight is almost directed toward the camera 11, but when the user is looking at the front or rearview mirror instead of the display device 40, The person's line of sight deviates from the direction of the camera 11.

  Based on the above considerations, the driver determination unit 24 detects the direction of the user's line of sight captured by the camera 11 while the mobile device 10 is in a moving state, using face recognition technology or the like, and based on the line of sight direction. Thus, it is determined whether or not the user of the mobile device 10 is a vehicle driver. Based on the result of detection of the line-of-sight direction for a predetermined period, the driver determination unit 24 takes a long time to direct the line of sight toward the front as viewed from the user, for example, the direction of the camera 11 continuously for a predetermined time or more. If the user does not turn the line of sight, the user is determined to be a driver. If the line of sight does not deviate in a specific direction and continues for a predetermined time or more, the user is directed toward the camera 11. Is determined not to be a driver. Thereby, since it can determine more accurately whether a user is a driver | operator, the convenience of a user can be improved. If the driver determination unit 24 cannot determine whether or not the user is a driver based on the detection result of the gaze direction for a predetermined period, the driver determination unit 24 obtains the detection result of the gaze direction for a predetermined period and then repeats the acquisition. You may judge. Thereby, erroneous determination can be reduced.

  The gripping state determination unit 25 determines the gripping state of the mobile device 10. The gripping state determination unit 25 grips the mobile device 10 by the user's hand based on the image captured by the camera 11 of the mobile device 10, the information detected by the sensor 12, the operation status of the operation unit 13, and the like. It is determined whether or not.

  FIG. 4 shows a correspondence relationship between the gripping state of the mobile device, the information detected by the sensor 12, the image captured by the camera 11, and the operation status of the operation unit 13. When the mobile device 10 is gripped by the user's hand, the mobile device 10 is greatly affected by camera shake, so the angle fluctuation range of the mobile device 10 detected by the gyro sensor is large, and the angle fluctuation cycle is long. Thus, the variation in the position of the user in the image captured by the camera 11 becomes large. Further, when the mobile device 10 is held by the user's hand, since the user often operates the mobile device 10 with the other hand, the frequency of operation on the operation unit 13 increases.

  On the other hand, when the mobile device 10 is fixed to a dashboard or the like, the mobile device 10 is not affected by camera shake, but is affected by the vibration of the vehicle, so the angle of the mobile device 10 detected by the gyro sensor. The fluctuation range is small, the angle fluctuation period is short, and the fluctuation in the position of the user in the image captured by the camera 11 is small. Further, when the mobile device 10 is fixed to a dashboard or the like, since the user rarely operates the mobile device 10 by reaching out, the frequency of operation on the operation unit 13 is reduced.

  Even when the mobile device 10 is placed on a seat or the like, the mobile device 10 is not affected by camera shake and is affected by the vibration of the vehicle. Since the influence is small, the angle fluctuation range of the portable device 10 detected by the gyro sensor is small, and the angle fluctuation period is long or medium. Usually, the user is not shown in the image captured by the camera 11. Further, since the user does not normally operate the portable device 10, the operation unit 13 is not operated.

  Based on the above considerations, the gripping state determination unit 25 has a predetermined variation range of the angle of the mobile device 10 based on an image captured by the camera 11 for a predetermined period, a detection result of the sensor 12, or an operation state with respect to the operation unit 13. Larger than the value, the angle fluctuation period is longer than the predetermined value, the change in the position of the user shown in the captured image is larger than the predetermined value, and the frequency of operation with respect to the operation unit 13 is higher than the predetermined value. It is determined that the person holds the hand. If at least one of the above criteria is satisfied, it may be determined that the mobile device 10 is being held by the hand, and if a plurality of conditions are satisfied, the mobile device 10 may be It may be determined that it is gripped. According to the former, it is possible to reduce erroneous determinations that are not determined as being held by the hand but being held by the hand, and the portable device 10 can be used more safely. According to the latter, it is possible to reduce misjudgment that determines that the hand is held but not held by the hand, and the convenience of the user can be improved. A score may be calculated by weighting each determination criterion, and it may be determined whether or not the hand is held by comparing the calculated score with a threshold value.

  The operation mode UI control unit 26 provides an operation mode interface. The user interface in the operation mode provides a launcher that can easily start only a predetermined part of functions or applications among a plurality of functions or applications that can be executed by the mobile device 10. The operation mode UI control unit 26 may display a user interface screen having higher visibility than the screen displayed on the display device 40 in the normal mode on the display device 40, or display a screen with high visibility on the display device 40. You may control an application, an operating system, etc. to display. For example, the amount of information to be displayed may be reduced, the display size of character information and the like may be increased, the saturation and contrast of display colors may be increased, and the screen of the display device 40 may be brightened. The driving mode UI control unit 26 can be performed in the driving mode, such as voice or gesture, without the driver driving the vehicle gazing at the portable device 10 or using the hand. Input may be accepted.

  The operation mode UI control unit 26 activates an application by the application activation unit 27 when requested by the user to activate an application that can be executed even in the operation mode, while the operation mode UI control unit 26 restricts execution of the application. The application is not started when the start is requested by the user. As a result, it is possible to appropriately limit the execution of an application that should be restricted during execution of the vehicle while allowing the execution of an application that can be executed even while the vehicle is operating. Safety at the time of using 10 can be improved.

  The operation mode UI start determination unit 28 determines whether or not to start the operation mode and switch from the normal mode when the normal mode user interface is provided. The operation mode UI start determination unit 28 determines that the display device 40 is ON by the display ON / OFF determination unit 21, determines that the mobile device 10 is moving by the movement state determination unit 22, and determines the position determination unit 23. When the mobile device 10 is determined to be on the road by the driver, and the driver determination unit 24 determines that the user of the mobile device 10 is the driver of the vehicle, the user interface is changed from the normal mode to the user interface in the driving mode. To the operation mode UI control unit 26. Thereby, the situation which should restrict | limit the use of the portable apparatus 10 can be determined more correctly.

  The operation mode UI end determination unit 29 determines whether to end the operation mode and return to the normal mode when the user interface for the operation mode is provided. When the movement state determination unit 22 determines that the mobile device 10 has not moved for a predetermined time (T2) or longer, the driving mode UI end determination unit 29 stops the vehicle on a road shoulder or a parking lot, and the mobile device 10 Therefore, the operation mode UI control unit 26 is instructed to end the operation mode and return to the normal mode. Thereafter, the restriction on the function of the mobile device 10 is released, and the user can use the mobile device 10 as usual. When the operation mode UI end determination unit 29 receives an operation input requesting the end of the operation mode UI from the user of the mobile device 10, the operation mode UI end determination unit 29 ends the operation mode and switches to the normal mode. As a result, after the driver of the vehicle stops the vehicle, if the user wants to use the portable device 10 in the normal mode before the time T2 has elapsed and automatically switched to the normal mode, the operation mode is manually ended. Therefore, it is possible to improve the convenience for the user.

  The driver determination cancellation determination unit 30 determines whether or not to cancel the determination result after the driver determination unit 24 determines that the user of the mobile device 10 is a driver of the vehicle. The driver determination cancellation determination unit 30 determines that the moving state determination unit 22 has not moved for a predetermined time (T3) or more, or the position determination unit 23 causes the mobile device 10 to remain on the road for a predetermined time or more. If it is determined that the user is away, the determination result that the user of the mobile device 10 is the driver of the vehicle is canceled. The driver determination cancellation determination unit 30 cancels the determination result when an operation input requesting cancellation of determination that the driver is a driver is received from the user. Thereby, for example, when the driver of the vehicle wants to use the mobile device 10 in the normal mode after the time T3 has elapsed and before the function restriction is automatically released after the vehicle gets off the vehicle, it is manually released. be able to. In order to allow the user to manually cancel the determination result, the time T3 until the driver determination cancellation determination unit 30 automatically cancels the determination result may be longer than T1 and T2.

  As described above, when the driver determination unit 24 determines that the user of the mobile device 10 is the driver of the vehicle, the determination result is maintained until a condition for canceling the determination result is satisfied. Is done. Therefore, even if the user interface that has been switched to the operation mode is terminated by an instruction from the operation mode UI end determination unit 29 and returned to the user interface in the normal mode, the mobile state 10 is subsequently moved by the movement state determination unit 22. If it is determined that the vehicle has moved for a predetermined time (T1) or longer, the operation mode UI start determination unit 28 instructs the operation mode UI control unit 26 to switch to the operation mode again. In this case, the determination by the driver determination unit 24 is omitted.

  After the determination result is canceled by the driver determination cancellation determination unit 30, the mobile device 10 cannot be switched to the operation mode only by moving the mobile device 10 by T1 or more. However, when the user of the mobile device 10 resumes driving the vehicle. The driver determination unit 24 again determines that the user of the portable device 10 is the driver of the vehicle, and switches to the driving mode.

  FIG. 5 is a flowchart illustrating the procedure of the method for controlling the mobile device according to the embodiment. In the mobile device 10, the operation mode UI start determination unit 28 determines that the display device 40 is ON by the display ON / OFF determination unit 21 (S <b> 10), or the mobile state 10 is moving by the movement state determination unit 22. Whether the mobile device 10 is determined to be present (S12), whether the mobile device 10 is determined to be on the road by the position determination unit 23 (S14), or whether the user of the mobile device 10 is a driver of the vehicle by the driver determination unit 24 If it is determined (S16) and all the determination results are affirmative (Y of S10, Y of S12, Y of S14, and Y of S16), the driver determination flag is turned ON (S18). ), The operation mode UI control unit 26 is instructed to switch the user interface from the normal mode to the user interface in the operation mode (S20). If any of the determination results is negative (N in S10, N in S12, N in S14, or N in S16), the process returns to S10 and the determination is continued.

  As described above, the determination execution frequency can be reduced by applying the plurality of determination criteria in an appropriate order, so that the processing load and power consumption can be reduced. For example, when the display device 40 is OFF, the user is using the mobile device 10 regardless of whether the display device 40 is moving, on the road, or a driver. Therefore, it is possible to determine that the user of the mobile device 10 is not driving the vehicle, without performing these determinations.

  FIG. 6 is a flowchart illustrating the procedure of the method for controlling the portable device according to the embodiment. FIG. 5 shows a procedure until it is determined that the user of the mobile device 10 is a driver of the vehicle, but FIG. 6 shows that the user of the mobile device 10 is determined to be a driver of the vehicle. To the procedure until the determination result is canceled.

  When the user interface in the operation mode is activated (Y in S40), the gripping state determination unit 25 determines whether or not the user is gripping the mobile device 10 by hand (S42) and grips it by hand. If it is determined that the mobile device 10 is being operated (Y in S42), a warning is given not to operate the mobile device 10 during driving (S44), and the mobile device 10 cannot be operated until it is determined that the hand is not being held. Therefore, the display device 40 is turned off (S46). When it is not determined that the hand is held (N in S42), the operation mode UI end determination unit 29 determines whether or not to end the operation mode (S48). When it is determined that the vehicle has not moved more than T2 (Y in S48), the operation mode UI control unit 26 ends the operation mode and returns to the normal user interface (S50), and the vehicle moves more than T2. If it is not determined that it is not (N in S48), the operation mode is continued.

  In S40, when the operation mode UI is not activated (N in S40), the operation mode UI start determination unit 28 determines whether to start the operation mode (S52). When it is determined that the vehicle is moving on the road for T1 or more (Y in S52), the operation mode UI control unit 26 starts the operation mode and switches to the user interface of the operation mode (S54). When it is not determined that the vehicle is moving on the road for T1 or more (N in S52), the normal mode is continued.

  Subsequently, the driver determination cancellation determination unit 30 determines whether or not to cancel the determination result that the user of the mobile device 10 is the driver of the vehicle (S56). When it is determined that the mobile device 10 has not moved by T3 or more, or the mobile device 10 is not on the road (Y in S56), the driver determination flag is turned OFF, and the process ends. When it is not determined that the mobile device 10 has not moved more than T3 or the mobile device 10 is not on the road (N in S56), the process returns to S40 and the above procedure is performed until the driver determination flag is turned off. repeat.

It is possible to improve user convenience. In addition, since the user interface can be switched appropriately and the use of mobile devices can be restricted while driving the vehicle, safety when using the mobile device is improved, and traffic accidents and traffic caused by the use of the mobile device are improved. The frequency of legal violations can be reduced.
