[Overview of information terminal control system]
FIG. 1 is a schematic diagram of an information terminal control system according to the present embodiment. The information terminal control system includes a user terminal 1. The number of user terminals 1 included in the information terminal control system is not limited. The information terminal control system may include other devices such as servers and terminals.

The user terminal 1 is an information terminal used by the user, for example, a smartphone, a tablet terminal, or the like. The user is a person who uses the user terminal 1. The user terminal 1 has a display unit such as a liquid crystal display for displaying information.

The outline of the process executed by the user terminal 1 will be described below with reference to FIG. The user terminal 1 acquires the inclination of the user terminal 1 while displaying information on the display unit in response to an operation by the user. The user terminal 1 calculates the angle of the display unit corresponding to the acquired inclination of the user terminal 1.

The user terminal 1 displays the visibility of the information displayed on the display unit when the angle of the display unit is not included in the predetermined range on the display unit when the angle of the display unit is included in the range. Display control is performed so that the visibility of the information to be displayed is lower than the visibility. The range of the angle of the display unit is a range in which it is difficult to cause an abnormality in the user's neck. For example, the display unit is close to vertical, that is, the normal angle of the display unit is close to 0 degrees with respect to the horizontal plane. It is a range showing. The user terminal 1 reduces the visibility of the information displayed on the display unit by, for example, reducing the brightness of the display unit.

As described above, when the angle of the display unit is not within the predetermined range, the user terminal 1 lowers the visibility of the information displayed on the display unit as compared with the case where the angle of the display unit is within the predetermined range. As a result, the user naturally adjusts the inclination of the user terminal 1 so that the angle of the display unit falls within a predetermined range in order to make the display unit easy to see. Therefore, the user terminal 1 can improve the abnormality of the user's neck that may occur due to the use of the user terminal 1 while allowing the user to continue using the user terminal 1.

[Configuration of user terminal 1]
FIG. 2 is a block diagram of the user terminal 1 according to the present embodiment. In FIG. 2, the arrows indicate the main data flows, and there may be data flows other than those shown in FIG. In FIG. 2, each block shows not a hardware (device) unit configuration but a functional unit configuration. Therefore, the block shown in FIG. 2 may be mounted in a single device, or may be mounted in a plurality of devices separately. Data can be exchanged between blocks via any means such as a data bus, a network, and a portable storage medium.

The user terminal 1 has a storage unit 11, a display unit 12, and a control unit 13. The user terminal 1 is not limited to the specific configuration shown in FIG. The user terminal 1 is not limited to one device, and may be configured by connecting two or more physically separated devices by wire or wirelessly.

The storage unit 11 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, and the like. The storage unit 11 stores in advance the program executed by the control unit 13. The storage unit 11 may be provided outside the user terminal 1, and in that case, data may be exchanged with the control unit 13 via a network. The display unit 12 is a display device such as a liquid crystal display capable of displaying information. The display unit 12 may be a touch screen capable of detecting the position of contact by a human.

The control unit 13 includes an acquisition unit 131, an estimation unit 132, a determination unit 133, a notification unit 134, and an output control unit 135. The control unit 13 is, for example, a processor such as a CPU (Central Processing Unit), and by executing a program stored in the storage unit 11, the acquisition unit 131, the estimation unit 132, the determination unit 133, the notification unit 134, and the output control Functions as part 135. At least some of the functions of the control unit 13 may be performed by an electric circuit. Further, at least a part of the functions of the control unit 13 may be executed by a program executed via the network.

The acquisition unit 131 acquires input information input by the user for estimating the degree of abnormality occurring in the neck of the user using the user terminal 1. The user terminal 1 causes the display unit 12 to display a setting screen for inputting input information.

FIG. 3 is a front view of the user terminal 1 displaying the setting screen. The setting screen includes an input area 121 for inputting input information for estimating the degree of abnormality occurring in the user's neck. The input area 121 accepts inputs such as the presence / absence of stiff shoulders, the degree of stiff shoulders, and the usage time of the user terminal 1. As other information, input of information such as the presence or absence of eye strain and the degree of eye strain may be accepted.

The acquisition unit 131 acquires the content input to the input area 121 as input information. The acquisition unit 131 stores the acquired input information in the storage unit 11 in association with the identification information for identifying the user. When the user terminal 1 is used by a specific user such as a smartphone, the input information may be stored without being associated with the identification information for identifying the user. The input information is not limited to the specific information shown here, and may include other information used for estimating the degree of abnormality occurring in the user's neck, such as a test result by a medical institution.

While the user is using the user terminal 1, that is, while the user terminal 1 is displaying information to the user, the acquisition unit 131 acquires the inclination of the user terminal 1. The acquisition unit 131 acquires the inclination of the user terminal 1 in the three-dimensional space by using, for example, the gyro sensor included in the user terminal 1. The inclination of the user terminal 1 is, for example, a rotation angle with respect to each of three axes orthogonal to each other in a three-dimensional space.

The estimation unit 132 estimates the degree of abnormality occurring in the user's neck based on the input information stored in the storage unit 11 by the user. The estimation unit 132 calculates a score corresponding to the degree of abnormality according to a predetermined rule from, for example, the presence / absence of stiff shoulders indicated by the input information, the degree of stiff shoulders, and the usage time of the user terminal 1. The score may be a numerical value or may be classified into "high", "medium", and "low".

Further, the estimation unit 132 may estimate the degree of abnormality occurring in the user's neck based on the image captured by the user, such as a camera included in the user terminal 1. The estimation unit 132 performs known image recognition processing on the captured image, for example, and identifies whether or not the user's head is in the forward leaning posture. Then, the estimation unit 132 measures the time when the user's head is in the forward leaning posture, and estimates that the longer the cumulative time is, the larger the degree of abnormality is, and the shorter the cumulative time is, the smaller the degree of abnormality is. The estimation unit 132 is not limited to the specific method shown here, and may estimate the degree of abnormality occurring in the user's neck by other methods.

When the determination unit 133 and the output control unit 135, which will be described later, do not use the degree of abnormality, the acquisition unit 131 may not acquire the input information, and the estimation unit 132 may not estimate the degree of abnormality. ..

The determination unit 133 calculates the angle of the display unit 12 corresponding to the inclination of the user terminal 1 by analyzing the inclination of the user terminal 1 acquired by the acquisition unit 131. The determination unit 133 calculates the angle of the normal of the display unit 12 with respect to the horizontal plane by using, for example, the rotation angle of each of the three axes of the user terminal 1 and the information regarding the shape of the user terminal 1.

The determination unit 133 determines a reference range of the angle of the display unit 12 as a reference for display control. The reference range is a range in which it is difficult for an abnormality to occur in the user's neck. The reference range is a predetermined range including 0 degrees with respect to the horizontal plane, and is, for example, a range of −30 degrees or more and +30 degrees or less. If the angle of the normal line of the display unit 12 is within such a reference range, the user is looking at the display unit 12 in a state close to vertical, so that the user's neck is less likely to be burdened and abnormalities are less likely to occur.

Further, the determination unit 133 may determine a different reference range depending on the degree of abnormality estimated by the estimation unit 132. In this case, the determination unit 133 determines a narrower reference range as the degree of abnormality is higher, and determines a wider reference range as the degree of abnormality is lower. As a result, when the degree of abnormality in the user's neck is large, the user terminal 1 urges the user to adjust the inclination of the user terminal 1 at an early stage by narrowing the reference range, and the user's neck 1 is used. It is possible to easily improve the abnormality of.

Further, the determination unit 133 may determine a different reference range according to at least one of the function executed by the user terminal 1, the position of the user terminal 1, and the time. The function executed by the user terminal 1 includes, for example, an application executed by the processor of the user terminal 1. The determination unit 133 determines, for example, a reference range narrower when the user terminal 1 is performing a specific function than when it is not. As a result, when the user terminal 1 is using a function that leads to long-term use such as SNS (Social Networking Service) or a game, the reference range is narrowed so that the user can use the user terminal 1 at an early stage. It can be encouraged to adjust the tilt, and it can be easier to improve the abnormality of the user's neck.

The determination unit 133 determines, for example, a reference range narrower when the position of the user terminal 1 is within a predetermined area or when the time is within a predetermined range. The user terminal 1 does not reduce the visibility of the display unit 12 because it is assumed that the posture of the user terminal 1 is limited when the position or time of the user terminal 1 indicates that the user is commuting to work. On the other hand, the user terminal 1 reduces the visibility of the display unit 12 because it is assumed that there is no restriction on the posture when the position or time of the user terminal 1 indicates that the user is at home. .. As a result, the user terminal 1 can improve the convenience of the function according to the present embodiment to the user.

The determination unit 133 determines whether or not the angle of the display unit 12 corresponding to the inclination of the user terminal 1 acquired by the acquisition unit 131 is included in the reference range. Based on the determination result by the determination unit 133, the notification unit 134 and the output control unit 135 perform the subsequent processing.

Further, the determination unit 133 may determine whether or not the gaze state of the user terminal 1 by the user satisfies a predetermined condition, in addition to whether or not the angle of the display unit 12 is included in the reference range. In this case, the determination unit 133 performs known image recognition processing on the image captured by the user, such as a camera included in the user terminal 1, and is the user gazing at the display unit 12 for a predetermined time or longer? Judge whether or not. Then, the determination unit 133 determines whether or not the angle of the display unit 12 is included in the reference range, provided that the user is gazing at the display unit 12 for a predetermined time or longer, for example. Further, the determination unit 133 may determine whether or not the user is gazing at the display unit based on the distance between the user's eyes and the display unit 12. As a result, when the user is not gazing at the display unit 12, the user terminal 1 can prevent the display unit 12 from performing display control, assuming that the influence on the user's neck is small.

Further, the determination unit 133 may change the reference range according to the gaze state of the user terminal 1 by the user, and may determine whether or not the angle of the display unit 12 is included in the changed reference range. As a result, the user terminal 1 urges the user to adjust the inclination of the user terminal 1 at an early stage by narrowing the reference range when the user is gazing at the display unit 12 for a predetermined time or longer. It can be easy to improve the abnormality of the neck.

When the determination unit 133 determines that the angle of the display unit 12 is not included in the reference range according to the determination result by the determination unit 133, the notification unit 134 includes the angle of the display unit 12 in the reference range. Notify the user that there is no such thing. The notification unit 134 causes the display unit 12 to display, for example, a notification indicating that the angle of the display unit 12 is not included in the reference range.

FIG. 4 is a front view of the user terminal 1 displaying the notification by the notification unit 134. The user terminal 1 displays the display information 122 generated by a function such as an SNS or a game on the display unit 12. The notification unit 134 superimposes on the display information 122 and displays the notification information 123 on the display unit 12, which indicates that the angle of the display unit 12 is not included in the reference range, that is, the posture of the user is bad. ..

The notification unit 134 includes the angle of the display unit 12 in the reference range by outputting sound from the user terminal 1 or vibrating the user terminal 1 in place of or in addition to the display on the display unit 12. The user may be notified that the notification has not been made.

After the notification unit 134 gives the notification, the output control unit 135 controls the display of the visibility of the information displayed on the display unit 12 according to the determination result by the determination unit 133. The output control unit 135 performs display control, for example, after a predetermined time (for example, 10 seconds) has elapsed from the notification unit 134 giving a notification.

Further, depending on the degree of abnormality estimated by the estimation unit 132, either the notification by the notification unit 134 or the display control by the output control unit 135 may be performed. For example, the output control unit 135 performs display control when the degree of abnormality satisfies a predetermined condition, and the notification unit 134 notifies when the degree of abnormality does not satisfy the predetermined condition. As a result, the user terminal 1 gives a notification by the notification unit 134 when the degree of abnormality in the user's neck is low, and displays control by the output control unit 135 when the degree of abnormality in the user's neck is high. Controls can be flexibly switched by doing so.

FIG. 5 is a schematic diagram for explaining display control performed by the output control unit 135 according to the determination result by the determination unit 133. The output control unit 135 sets the visibility of the information displayed on the display unit 12 when the determination unit 133 determines that the angle of the display unit 12 is not included in the reference range, and the angle of the display unit 12 sets the reference range. When the determination unit 133 determines that the information is included, the display control is performed so that the visibility of the information displayed on the display unit 12 is lower than the visibility.

The output control unit 135 controls the display by, for example, changing the brightness of the display unit 12, that is, making the display unit 12 darker or brighter. In the upper figure of FIG. 5, since the determination unit 133 determines that the angle of the display unit 12 is not included in the reference range, the output control unit 135 reduces the visibility of the display information 122 by reducing the brightness. .. On the other hand, in the lower figure of FIG. 5, since the determination unit 133 determines that the angle of the display unit 12 is included in the reference range, the output control unit 135 improves the visibility of the display information 122 by increasing the brightness. There is. The output control unit 135 repeatedly controls the visibility of the display information 122 every time the angle determination result of the display unit 12 is updated.

As a result, the user naturally adjusts the inclination of the user terminal 1 so that the display unit 12 is close to vertical in order to make the display unit 12 easier to see. Therefore, the user terminal 1 can improve the abnormality of the user's neck that may occur due to the use of the user terminal 1 while allowing the user to continue using the user terminal 1.

The output control unit 135 controls the display of the visibility of the display information 122, and causes the display unit 12 to display the angle information 124 indicating the angle of the display unit 12 and the reference range. The angle information 124 represents, for example, the reference range by a white area in a black circle, and the angle of the display unit 12 by a rectangle that rotates with respect to the center of the circle. In the example of FIG. 5, in the angle information 124, the angle of the display unit 12 is within the reference range when the rectangle is close to vertical, and the angle of the display unit 12 is out of the reference range when the rectangle is close to horizontal. It represents that. By referring to the angle information 124, the user can grasp the relationship between the angle of the display unit 12 and the reference range, and can easily adjust the inclination of the user terminal 1.

Further, the output control unit 135 may perform different display control depending on the degree of abnormality estimated by the estimation unit 132. For example, the output control unit 135 increases the amount of decrease in visibility when the angle of the display unit 12 is not included in the reference range as the degree of abnormality increases, and the angle of the display unit 12 increases as the degree of abnormality decreases. Reduce the amount of decrease in visibility when it is not included in the reference range. Further, the output control unit 135 may set the brightness of the display unit 12 to zero when the degree of abnormality satisfies a predetermined condition and the angle of the display unit 12 is not included in the reference range. As a result, when the degree of abnormality in the user's neck is large, the user terminal 1 significantly reduces the visibility of the information displayed on the display unit 12, thereby tilting the user terminal 1 to the user at an early stage. It can be encouraged to adjust, and it can be easier to improve the abnormality of the user's neck.

Further, the output control unit 135 may perform different display control in consideration of the distance between the user's eyes and the display unit 12 in addition to the angle of the display unit 12. For example, even if the angle of the display unit 12 is included in the reference range, the output control unit 135 reduces the visibility when the distance between the user's eyes and the display unit 12 is less than a predetermined threshold value. The display may be performed so as not to reduce the visibility only when the angle of the display unit 12 is included in the reference range and the distance between the eyes and the display unit 12 is equal to or larger than a predetermined threshold value. Further, the output control unit 135 may increase the amount of decrease in visibility as the distance between the user's eyes and the display unit 12 decreases. As a result, the user terminal 1 can prevent the user from bringing his / her eyes too close to the display unit 12, and can suppress eye strain, deterioration of eyesight, etc. in addition to improvement of abnormalities in the neck.

The output control unit 135 controls the visibility of the information displayed on the display unit 12 according to at least one of the function executed by the user terminal 1, the position of the user terminal 1, and the time. You may switch the presence or absence. The output control unit 135 performs display control, for example, on condition that the user terminal 1 is executing a specific function. As a result, the user terminal 1 can easily improve the abnormality of the user's neck by applying the display control only to the functions that lead to long-term use such as SNS and games.

The output control unit 135 performs display control, for example, on the condition that the position of the user terminal 1 is within a predetermined area or on the condition that the time is within a predetermined range. As a result, for example, when the user is commuting, it is assumed that the posture is restricted. Therefore, the user terminal 1 does not apply the display control if the position or time corresponds to the user's commuting. .. On the other hand, since it is assumed that there is no restriction on the posture when the user is at home, the user terminal 1 applies display control at a corresponding position or time while the user is at home. As a result, the user terminal 1 can improve the convenience of the function according to the present embodiment to the user.

Further, in addition to the display control of the visibility of the information displayed on the display unit 12, the output control unit 135 outputs the sound output by the sound output unit such as the speaker provided in the user terminal 1 according to the angle of the display unit 12. Voice control may be performed to change the volume. For example, when the determination unit 133 determines that the angle of the display unit 12 is not included in the reference range, the output control unit 135 sets the volume of the sound output by the audio output unit to the reference range of the angle of the display unit 12. When the determination unit 133 determines that it is included, the voice control is performed so that the volume of the voice is lower than the volume of the voice output by the voice output unit. As a result, the user naturally adjusts the inclination of the user terminal 1 in order to make it easier to hear the voice. Therefore, the user terminal 1 can improve the abnormality of the user's neck that may occur due to the use of the user terminal 1 while allowing the user to continue using the user terminal 1.

[Explanation of information terminal control method]
FIG. 6 is a diagram showing an example of a flowchart of an information terminal control method executed by the user terminal 1 according to the present embodiment. The acquisition unit 131 acquires input information input by the user for estimating the degree of abnormality occurring in the neck of the user using the user terminal 1 (S11).

When the determination unit 133 determines that the angle of the display unit 12 is not included in the reference range, the notification unit 134 notifies the user that the angle of the display unit 12 is not included in the reference range. Do (S17). Notification by the notification unit 134 may not be performed.

The output control unit 135 controls the display of the visibility of the information displayed on the display unit 12 according to the determination result by the determination unit 133 (S18). That is, the output control unit 135 uses the angle of the display unit 12 as a reference for the visibility of the information displayed on the display unit 12 when the determination unit 133 determines that the angle of the display unit 12 is not included in the reference range. Display control is performed so that the visibility of the information displayed on the display unit 12 is lower than the visibility of the information displayed on the display unit 12 when the determination unit 133 determines that the range is included.

When the predetermined end condition (for example, that the predetermined end operation has been performed in the user terminal 1) is not satisfied (NO in S19), the user terminal 1 repeats steps S12 to S17. When the predetermined end condition is satisfied (YES in S19), the user terminal 1 ends the process.

[Effect of this embodiment]
