[0008] The embodiments for implementing this disclosure will be described below with reference to the drawings. Note that the embodiments described below are just one example of what this disclosure provides, and the contents of this disclosure should not be interpreted as being limited based on the following description.

[0009] A walker is known as one of devices that assist a user in walking. There are multiple types of walkers, and among them, a pickup-type walker (fixed walker) of the type in which the user lifts the walker body by themselves to move forward is known. Hereinafter, the pickup-type walker is simply referred to as a walker.

[0010] Descriptions of methods for a user to walk using a walker have generally often been premised on the user stepping straight forward with their foot. However, when such a walker is used by, for example, a user with hemiplegia, the user cannot simply step straight forward. Similarly, when such a walker is used by an elderly user with stiff joints or a user with some disease, the user similarly cannot step straight forward.

[0011] Accordingly, when a user with hemiplegia or the like uses the walker, the user often supports their body with the walker and steps forward by rotating the paralyzed side using their body. In this case, the user moves their foot so as to rotate it outward from the body, but in a walker designed for an ordinary walking pattern, there has been a problem that the rotating foot easily collides with the leg (rear leg) supporting the walker.

[0012] Generally, walkers are designed with consideration to secure as much space around the user's feet as possible on the premise of ordinary walking. However, pickup-type walkers are often used especially indoors. Accordingly, a smaller outer dimension provides better maneuverability, so such walkers are designed not to have an unnecessarily large width.

[0013] Therefore, as described above, in the case of a user with hemiplegia, the foot on the walking side, which is moved by rotating outward from the body, easily collides with the leg of the walker, making the walker difficult to use.

[0014] As described above, the following embodiment describes a walker based on an unprecedented concept of proposing an easy-to-use walker even for users with hemiplegia.

[0015] In the following explanation, the front of a user of a walker will be referred to as "front," the back as "back," the right side as "right," and the left side as "left."

[0016] Furthermore, the users are those who use a walker. Users are not limited to sick people or those requiring care, but also include healthy individuals. In addition, users include not only adults and the elderly, but also children, etc. The walker in this embodiment is most effective when used by users who walk by rotating their leg outward, such as those with hemiplegia. It is also effective when the user has injured one leg.

[0017] Furthermore, staff members include medical professionals at the hospital where the user is hospitalized, and staff at the facility where the user resides. In the case of a user at home, staff members also include family members who provide care and nursing.

[0018] [1. First Embodiment] [1.1 Overall Structure] Figure 1 is a perspective view showing the entire walker 1. Figure 2 is a side view of the walker 1 viewed from the left, showing the left side frame 10.

[0019] The side frames 10 are arranged in pairs on the left and right sides and support the user's body. The side frames 10 are connected on the front side of the walker 1 by one or more connecting members. In this embodiment, they are connected by a foldable first connecting member 32 and a second connecting member 34.

[0020] The side frame 10 includes a front frame 12 that extends vertically and forms the front legs of the walker 1, a rear frame 14 that forms the rear legs of the walker 1, and an upper frame 16 that connects the upper end of the front frame 12 and the upper end of the rear frame 14.

[0021] Furthermore, the side frame 10 may have one or more frames arranged substantially parallel to the upper frame 16 in order to reinforce the side frame 10. In this embodiment, the side frame 10 has a first horizontal frame 22 and a second horizontal frame 24 at an intermediate position in the vertical direction.

[0022] The front frame 12 and the rear frame 14 are connected at their upper ends by the upper frame 16. In this embodiment, the front frame 12, the upper frame 16, and the rear frame 14 may also be integrally formed by bending a pipe with a substantially circular cross-section. The material of the pipe may be a metal such as aluminum, iron, stainless steel, or titanium, or a synthetic resin such as reinforced plastic, or wood, etc.

[0023] Furthermore, the connection between the front frame 12 and the upper frame 16 may be bent in an arc shape, as shown in Figures 1 and 2. Alternatively, the connection between the front frame 12 and the upper frame 16 may be at an angle, or straight members may be connected.

[0024] The upper frame 16 may have a gripping portion 20. The gripping portion 20 may be made of, for example, synthetic resin such as plastic, rubber, cushion, etc. The gripping portion 20 is the part that the user grips when walking with the walker 1. Preferably, the gripping portion 20 is shaped to make it easy for the user to grip the upper frame 16. The gripping portion 20 may be provided so as to wrap around the upper frame 16. Alternatively, instead of the gripping portion 20, the upper frame 16 may be shaped to be easy for the user to grip.

[0025] The first transverse frame 22 is fixed to the front frame 12 and the rear frame 14. The first transverse frame 22 may be connected to the front frame 12 and the rear frame 14 by welding, for example, or it may be fixed by fastening members such as screws. Alternatively, the first transverse frame 22 may be formed integrally with the front frame 12 and the rear frame 14.

[0026] Furthermore, it is preferable that the first horizontal frame 22 is connected to the front frame 12 and the rear frame 14 at approximately a right angle. For this reason, the first horizontal frame 22 may be gently bent in a V-shape near the center to match the inclination with the front frame 12 and the rear frame 14. The first horizontal frame 22 may be provided towards the upper side in the vertical direction of the side frame 10.

[0027] Furthermore, the second horizontal frame 24 is provided between the front frame 12 and the rear frame 14, which are lower than the first horizontal frame 22, in order to reinforce the side frame 10.

[0028] The second horizontal frame 24 can be fixed to the front frame 12 and the rear frame 14 by either method. In this embodiment, for example, the end of the second horizontal frame 24 is curved to make it parallel to the front frame 12 and the rear frame 14. For example, the second horizontal frame 24 has a roughly U-shape when viewed from the side.

[0029] The second horizontal frame 24 may be fixed to the front frame 12 and the rear frame 14 using fastening members such as screws. Alternatively, the second horizontal frame 24 may be fixed to the front frame 12 and the rear frame 14 by welding, or it may be integrally formed.

[0030] The first connecting member 32 and the second connecting member 34 are members for connecting the left and right side frames 10. For example, the first connecting member 32 and the second connecting member 34 may be made of pipes, just like the side frames 10. Alternatively, the first connecting member 32 and the second connecting member 34 may be made of materials different from those of the side frames 10.

[0031] The first connecting member 32 and the second connecting member 34 may be foldable. For example, the first connecting member 32 and the second connecting member 34 may be foldable near their centers, allowing the user to fold the walker 1.

[0032] Furthermore, the first connecting member 32 may have a locking mechanism. For example, when in use, the user locks the first connecting member 32 in an unfolded state (straightened state). When folding, the user releases the locking mechanism, making the first connecting member 32 foldable.

[0033] The second connecting member 34 is foldable, but does not necessarily have a locking mechanism. For example, when the first connecting member 32 is locked by its locking mechanism, the second connecting member 34 remains unfolded (in a straight line). When the locking mechanism of the first connecting member 32 is released, the second connecting member 34 also becomes foldable together with the first connecting member 32.

[0034] Furthermore, the side frame 10 may be provided with a non-slip surface made of rubber or the like at its lower end. For example, the front frame 12 may be provided with a non-slip surface 12A at its lower end, and the rear frame 14 may be provided with a non-slip surface 14A at its lower end.

[0035] Furthermore, the side frame 10 may have an adjustment mechanism for adjusting its length and width in the vertical direction. For example, the front frame 12 may have an adjustment mechanism 12B, and the rear frame 14 may have an adjustment mechanism 14B. For example, the lengths of the front frame 12 and the rear frame 14 can be changed by using the adjustment mechanisms 12B and 14B.

[0036] [1.2 Positional Relationships] Here, the positional relationship between the front frame 12, the rear frame 14, and the upper frame 16 will be explained with reference to Figure 3.

[0037] Figure 3(a) illustrates the position of the rear frame 14 in this embodiment. A characteristic of the walker 1 in this embodiment is that the lower end of the rear frame 14 is located further forward compared to conventional walkers.

[0038] The dashed line 18 in Figure 3(a) represents the position of the conventional rear frame. In contrast, the rear frame 14 of the walker 1 in this embodiment is characterized by having its lower end located further forward than in the conventional position.

[0039] As a result, when comparing the first angle R1 formed by the front frame 12 and the upper frame 16 with the second angle R2 formed by the rear frame 14 and the upper frame 16, angle R1 is larger than angle R2.

[0040] Furthermore, when the walker 1 is placed on the horizontal plane FL, comparing the angle R3 formed by the front frame 12 and the horizontal plane FL with the angle R4 formed by the rear frame 14 and the horizontal plane FL, R4 is larger.

[0041] In the conventional walker 1, the position of the rear frame 14 is at the position of the imaginary line 18. For example, the conventional walker 1 has an isosceles trapezoidal shape when viewed from the side, and the angle formed by the upper frame 16 and the front frame 12 is the same as the angle formed by the upper frame 16 and the rear frame 14. Therefore, the angle formed by the horizontal plane FL and the front frame 12 is the same as the angle formed by the horizontal plane FL and the rear frame 14.

[0042] As a result, a problem arose where the user's feet would hit the rear frame when walking with the walker 1. In this embodiment of the walker 1, the position P1 of the lower end of the rear frame 14 is moved forward compared to the position P2 of the lower end of the imaginary line 18 of the conventional rear frame. By moving P1 forward from P2, it is possible to prevent the user's feet from hitting the rear frame 14 when walking with the walker 1.

[0043] As shown in Figure 3(b), the rear frame 14 may be configured to be approximately perpendicular to the horizontal plane FL.

[0044] As an example of explanation, we will use specific numerical values ​​to describe the walker 1 in Figure 3(b). For example, in Figure 3(b), angle R4 is set to 90 degrees, whereas it was 84 degrees in the conventional product. Also, for example, angle R2 is set to 92.5 degrees, compared to 96 degrees in the conventional product. As a result, the distance W1 between P1, where the lower end of the rear frame 14 of this embodiment is located, and P2, where the lower end of the imaginary line 18 representing the conventional rear frame is located, is approximately 6 cm. In other words, in the walker 1 of this embodiment, the lower end of the rear frame 14 is positioned further forward by a distance W1 compared to the conventional walker.

[0045] Alternatively, R1 may remain at the same angle as the conventional product (96 degrees), and the upper frame 16 may be given a slope. For example, the upper frame of the conventional product was parallel to the horizontal plane FL, but the upper frame 16 of this embodiment has a slope that rises 2.5 degrees (angle R5 in Figure 3(b)) from the rear to the front.

[0046] Note that these values ​​are just examples and are not the only values ​​that can be used. For example, the angle R4 only needs to satisfy the following relationship. R3 < R4 ≦ 90 degrees

[0047] Furthermore, angle R2 should be smaller than angle R1. For example, the difference between angle R1 and angle R2 is preferably between 3 degrees and 6 degrees. Also, the difference between angle R1 and angle R2 is preferably within the range of a predetermined angle to angle R1 - 90 degrees. For example, if the predetermined angle is 3 degrees, then the difference between angle R1 and angle R2 is preferably between 3 degrees and 90 degrees. In other words, if the predetermined angle is 3 degrees, the relationship between angles R1 and R2 is as follows. 3 degrees≦R1-R2≦R1-90 degrees

[0048] Thus, the minimum angle of angle R2 may be such that the rear frame 14 is perpendicular to the mounting surface (for example, approximately 90 degrees). For example, some specific angles are listed below. If angle R1 is 96 degrees, the angle difference between angle R1 and angle R2 will be 3 to 6 degrees, and angle R2 will be 90 to 93 degrees. If angle R1 is 100 degrees, the angle difference between angle R1 and angle R2 will be between 3 and 10 degrees, and angle R2 will be between 90 and 97 degrees. If angle R1 is 105 degrees, the angle difference between angle R1 and angle R2 will be between 3 and 15 degrees, and angle R2 will be between 90 and 102 degrees.

[0049] Alternatively, when the upper frame 16 is horizontal, regardless of the angle of R1, the minimum angle of R2 may be such that the rear frame 14 is perpendicular to the mounting surface (for example, approximately 90 degrees).

[0050] Furthermore, the position P1 of the lower end of the rear frame 14 should be forward of the conventional position P2. That is, P1 should be between a position that is approximately perpendicular to the horizontal plane FL, which is the installation surface, from the position of the rear end of the upper frame 16, and P2, which is the position of the lower end of the conventional rear frame. Note that perpendicular to the installation surface, where the walker 1 is installed, is preferably 90 degrees, but is not limited to exactly 90 degrees and may include a range of manufacturing tolerances, assembly tolerances, etc.

[0051] In this embodiment, the distance W1 is set to 6 cm, but preferably the lower end of the rear frame 14 should be positioned closer to the front within the range of 2 cm to 6 cm.

[0052] Furthermore, although the inclination of the upper frame 16 was described as rising by 2.5 degrees from rear to front as an angle R5, it is preferable that the angle R5 falls within the range of 1.5 to 6 degrees.

[0053] Furthermore, in the example described above, the position of the rear frame 14 was moved forward by creating a difference between angles R1 and R2, but this can be achieved by other methods. Figure 3(c) shows the state in which the length of the front frame 12 has been extended.

[0054] For example, as shown in Figure 3(c), the front frame 12 may be configured to be longer than the rear frame 14. The front frame 12 may be made longer than the rear frame 14 from the start, or an attachment 12E may be provided as shown in Figure 3(c).

[0055] As a result, the lower end of the rear frame 14 of the walker 1 is positioned further forward compared to conventional walkers. In addition, the upper frame 16 is in an upward sloping position from rear to front.

[0056] [1.3 Example of Operation] Figure 4 is a schematic diagram illustrating the position of the feet and the position of the walker 1. In this embodiment, the walker 1 is positioned at positions PF1, PF2, PR1, and PR2. Here, position PF1 is the position of the left front frame 12, position PF2 is the position of the right front frame 12, position PR1 is the position of the left rear frame 14, and position PR2 is the position of the right rear frame 14. In addition, the positions of the rear frames of a conventional walker 1 are shown as PR3 on the left and PR4 on the right.

[0057] Here, the user's left foot is at position F10 and their right foot is at position F12. After supporting their weight with the walker 1, the user moves one foot forward. In Figure 4, by moving the right foot forward, the user moves from position F12 to position F14.

[0058] Here, the user's right foot moves along the trajectory shown by the dashed line V10. In conventional walkers, the rear frame is at position PR4, causing the user's right foot to hit it. In contrast, in this embodiment, the rear frame 14 is at position PR2, allowing the user's right foot to move without hitting it.

[0059] [1.4 Effects] Thus, with the walker 1 of this embodiment, the lower end of the rear frame is positioned further forward compared to conventional walkers. As a result, when the user walks using the walker 1, their feet do not come into contact with the rear frame 14, allowing for comfortable movement. Furthermore, when the user moves from the walker 1 to other devices (e.g., a bed, chair, toilet seat, lift, etc.), their feet do not come into contact with the rear frame 14. Similarly, when the user moves from other devices to the walker 1, their feet do not come into contact with the rear frame 14.

[0060] Furthermore, according to the walker 1 of this embodiment, the upper frame 16 has a gentle slope that rises from rear to front. This slope makes it easier for the user to support their body.

[0061] [2. Second Embodiment] The second embodiment describes a system S that utilizes the walker 1 described in the first embodiment.

[0062] Walkers were used to assist users with mobility, but their function was merely to aid in movement. However, given that walkers are used daily, there is a need for them to go beyond simply being a means of transportation and function as a device for acquiring information about the user's condition.

[0063] Furthermore, it is known that people who use walkers have a higher risk of falling than those who do not. Therefore, it is desirable to reduce the risk of falls for users and to promptly notify staff if a user does fall.

[0064] To solve these problems, a system S utilizing a walker 1 and a terminal device 2 capable of communicating with the walker 1 will be described in the following embodiment.

[0065] [2.1 Overall Structure] Figure 5 is a diagram showing an overview of system S, which includes a walker 1 and a terminal device 2. The walker 1 and the terminal device 2 may communicate with each other, for example, by wireless communication. The terminal device 2 is, for example, a terminal device used by the user, and may be an information processing device such as a smartphone, tablet, or computer.

[0066] [2.2 Hardware Configuration] Figure 6 is a diagram illustrating the functional configuration of the walker 1 and the terminal device 2. The walker 1 may have a control device having the functions shown in Figure 6. The control device is a device that is built into the walker 1 or attached externally. Hereafter, the control device in Figure 6 will be described as a function of the walker 1.

[0067] [2.2.1 Common Configuration] The control unit, storage, ROM, RAM, and communication unit of each component are described below.

[0068] The control unit (for example, control unit 100, control unit 200) is a functional unit for controlling the entire device. The control unit realizes various functions by reading and executing various programs stored in storage or ROM. The control unit may be realized by one or more control devices / arithmetic units (CPU (Central Processing Unit), SoC (System on a Chip)).

[0069] Storage (for example, storage 110, storage 210) is a non-volatile storage device capable of storing programs and data. For example, it may consist of a hard disk drive (HDD) or a storage device using semiconductor memory. Storage may also be an externally connectable storage device or storage medium, such as a USB memory stick, CD-ROM drive, or BD drive. Furthermore, storage may be, for example, a storage area located in the cloud.

[0070] ROM (for example, ROM120, ROM220) is a non-volatile memory that can retain programs and data even when the power is turned off. ROM may store, for example, the firmware of each device or initial applications.

[0071] RAM (for example, RAM130, RAM230) is the main memory primarily used by the control unit of each device during execution. RAM is a rewritable memory that temporarily holds data including programs read from the storage or ROM of each device, as well as execution results.

[0072] The communication unit (for example, communication unit 170, communication unit 270) is a communication interface for communicating with other devices. For example, it may be a network interface capable of providing wired or wireless connections. In this embodiment, it is possible to communicate with other devices via a network NW. The communication unit may also provide a function to connect to a mobile network (LTE (Long Term Evolution) / 4G / 5G / 6G).

[0073] [2.2.2 Walkers] As shown in Figure 6, the walker 1 includes a control unit 100, a storage unit consisting of a storage 110, a ROM 120, and a RAM 130, a notification unit 150, a sensor unit 160, and a communication unit 170.

[0074] The sensor unit 160 is a sensor capable of acquiring the user's state and movements. For example, the sensor unit 160 can detect load using a load sensor, detect electrical potential using a potential sensor, or detect blood flow using an optical sensor.

[0075] The sensor unit 160 may be a device built into the walker 1 or an external device. For example, as shown in Figure 7, the sensor unit 160 may be attached to the gripping part 20 provided on the upper frame 16.

[0076] When using the walker 1, the user grips the handle 20 so as to cover the sensor unit 160. This allows the sensor unit 160 to detect vibrations, potential differences, and moisture (sweat) from the user, depending on the type of sensor device.

[0077] The value detected by the sensor unit 160 (sensor value) is output to the control unit 100. Based on the sensor value, the control unit 100 can acquire the user's movements and biometric information.

[0078] Furthermore, the sensor unit 160 may be provided elsewhere. For example, the side frame 10 may have an acceleration sensor and an impact sensor built into it at any position. For example, an acceleration sensor (impact sensor) may be built into the rear frame 14. If the user's foot hits the rear frame 14, the impact can be detected.

[0079] Furthermore, the sensor unit 160 may be composed of other devices. For example, a sensor device may be connected to the walker 1 as an option. For example, a heart rate sensor may be provided separately on the walker 1.

[0080] Furthermore, the sensor unit 160 may detect the state of the walker 1. For example, the walker 1 may have one or more acceleration sensors built in. The control unit 100 outputs sensor values ​​output from the acceleration sensors to the control unit 100. Based on the received sensor values, the control unit 100 may determine the user's walking style, the number of falls, etc.

[0081] Furthermore, the sensor unit 160 may acquire sensor values ​​from a terminal device 2 connected via the communication unit 170. Additionally, the walker 1 may acquire sleep status from another device (for example, a sleep detection device).

[0082] The notification unit 150 notifies the user of various information. The notification unit 150 may be, for example, a sound output device (e.g., a piezoelectric buzzer) for outputting warning sounds or confirmation sounds, or it may be an audio output device such as a speaker.

[0083] Furthermore, the notification unit 150 may provide notifications using light, vibration, or other means in addition to sound. The notification unit 150 may also provide notifications to other devices. For example, if a problem occurs with the user, the notification unit 150 may notify the terminal device 2. The notification unit 150 may also provide notifications about the status of the walker 1 (for example, the power status or whether the user is using the walker 1 correctly).

[0084] [2.2.3 Terminal Devices] As shown in Figure 6, terminal device 2 includes a control unit 200, a storage unit consisting of a storage 210, a ROM 220, and a RAM 230, an operation unit 240, a display unit 250, and a communication unit 270.

[0085] The operation unit 240 is a device used by the user to operate the terminal device 2. The operation unit 240 may be implemented using hardware switches or software switches. For example, a software key may be implemented as the operation unit using a touch panel integrated with a display device. Alternatively, the operation unit 240 may be composed of an external device. For example, the terminal device 2 may use an operation device (e.g., a keyboard) connected to an interface such as USB.

[0086] The display unit 250 is a device capable of displaying various information and execution screens. The display unit 250 may be a device capable of displaying information, such as a liquid crystal display or an organic EL display, or it may utilize light-emitting elements such as LEDs. For example, the display unit 250 may display the power status or error status of the terminal device 2 based on the lighting status of the LEDs. The display unit 250 may also be composed of an external device. For example, the terminal device 2 may utilize a display device connected to a terminal capable of outputting video, such as HDMI® or DVI.

[0087] The functional configuration described above is just one example, and additional functions not shown in the diagram may be included or omitted as needed. For example, the walker 1 may have an operating unit and a display unit. Furthermore, the walker 1 may be operated via the terminal device 2, or receive notifications of necessary information via that device.

[0088] Furthermore, terminal device 2 may send notifications or displays to other devices. For example, terminal device 2 may send emails or other messages to other devices via the communication unit 270 regarding necessary information.

[0089] [2.3 Software Configuration] Next, the software configuration will be explained with reference to Figure 8. In the walker 1, the control unit 100 executes a program stored in the memory unit, which enables the sensor value acquisition unit 102, the biological information calculation unit 104, and the state determination unit 106.

[0090] The sensor value acquisition unit 102 acquires the sensor value output by the sensor unit 160. The sensor value acquisition unit 102 may also transmit the acquired sensor value to the terminal device 2 via the communication unit 170.

[0091] The biometric information calculation unit 104 calculates biometric information values ​​as values ​​related to the user's biometric information based on the sensor values ​​acquired by the sensor value acquisition unit 102. Here, the biometric information calculated by the biometric information calculation unit 104 includes values ​​related to the user's heart rate, body temperature, sweating amount, SpO2, blood pressure, blood glucose, etc. The biometric information calculation unit 104 uses sensor values ​​acquired from the sensor unit 160, which is capable of calculating biometric information. For example, when the biometric information calculation unit 104 calculates the user's heart rate, the sensor unit 160 is a sensor that operates as an electrical potential sensor. Also, when the biometric information calculation unit 104 calculates the user's sweating amount, the sensor unit 160 is a sensor capable of detecting moisture content.

[0092] The mechanism by which the biological information calculation unit 104 calculates biological information based on the sensor values ​​output by the sensor unit 160 can utilize prior art available at the time of any application, and therefore a detailed explanation is omitted.

[0093] Furthermore, the biometric information calculation unit 104 transmits the calculated biometric information and biometric information values ​​to the terminal device 2 via the communication unit 170.

[0094] The state determination unit 106 determines the state of the user, other than biometric information, from the sensor values ​​output by the sensor unit 160. For example, the state determination unit 106 can determine the movement of the user's load. The state determination unit 106 may also determine, for example, the time when the walker 1 was started to be used and the time when its use ended. Furthermore, the state determination unit 106 may determine, for example, that the user has fallen based on the change in the load value output from the sensor unit 160.

[0095] The status determination unit 106 determines the user's status and transmits it to the terminal device 2 via the communication unit 170.

[0096] In terminal device 2, the control unit 200 executes a program stored in the memory unit, thereby realizing the information acquisition unit 202, event determination unit 204, recommendation unit 206, and notification unit 208.

[0097] The information acquisition unit 202 acquires information from the walker 1 via the communication unit 270. Based on the acquired information, the information acquisition unit 202 determines the user's status and stores the acquired information. For example, the information acquisition unit 202 can acquire biometric information, biometric information values, sensor values ​​output by the sensor unit 160, and the user's status from the walker 1 via the communication unit 270.

[0098] The information acquisition unit 202 may also acquire other information. For example, it may acquire information about the user using the walker 1 (e.g., user ID, user name, disease information, etc.) or acquire the location of the walker 1.

[0099] The information acquisition unit 202 then stores the acquired sensor values ​​in chronological order in the sensor value storage area 212. The information acquisition unit 202 also stores the received biological information in the biological information storage area 214.

[0100] Figure 9(a) shows an example of biometric information stored in the user's biometric information memory area 214. Referring to Figure 9(a), the biometric information memory area 214 stores, for each user, the date and time (e.g., "2022 / 06 / 15 09:40:00"), and biometric information such as heart rate (e.g., "80" bpm), body temperature (e.g., "36.2" °C), and SpO2 (e.g., "99"%).

[0101] Here, biological information can be calculated or acquired at predetermined intervals. Furthermore, the timing of calculating biological information may differ depending on the type of biological information. For example, in Figure 9(a), heart rate is calculated every 20 seconds, while body temperature and SpO2 are calculated every minute.

[0102] The timing for calculating this biometric information may be configurable or predetermined.

[0103] The event determination unit 204 determines the events that have occurred to the user and stores them in the event storage area 218.

[0104] Figure 9(b) shows an example of the data structure of events stored in the event memory area 218. Events are stored with the date and time of occurrence and the type (content) of the event associated with them.

[0105] For example, the following events are possible as examples of events that the event determination unit 204 may determine.

[0106] • Collision. This event occurs when the user's foot hits the rear frame 14 of the walker 1. The event determination unit 204 may further store the location where the event occurred. For example, it may further store whether the rear frame 14 that the user's foot hit was on the "right" or "left" side. The event determination unit 204 may also store more precise location information on the rear frame 14 and the force of the impact of the foot collision.

[0107] • Load imbalance. This event occurs when the user's load is imbalanced beyond a predetermined threshold. For example, if the difference in load values ​​between the left and right gripping parts 20 exceeds a predetermined value, this is recorded as an event.

[0108] • Abnormal biometric values. A first threshold, which is the upper limit, and a second threshold, which is the lower limit, are set in advance for each biometric value. When the biometric value exceeds (or falls below) the predetermined threshold, it is recorded as an event. For example, if a user sets "130" as the first threshold and "50" as the second threshold for heart rate, the event determination unit 204 determines and records it as an event when the heart rate exceeds 130.

[0109] Furthermore, these event types may be stored along with levels and numerical values. For example, the event determination unit 204 may store levels based on the magnitude of the collision and the magnitude of the load imbalance. Also, for example, the event determination unit 204 may store the heart rate in addition to storing "heart rate (high)" when the heart rate is high.

[0110] The recommendation unit 206 makes recommendations based on the information acquired by the information acquisition unit 202 and the events determined by the event determination unit 204. For example, the recommendation unit 206 can recommend an appropriate walker (product) or recommend visiting a medical institution.

[0111] The notification unit 208 provides notifications based on information acquired by the information acquisition unit 202 and events determined by the event determination unit 204. The notification unit 208 may, for example, display a notification on the display unit 250 of the terminal device 2 (for example, display an event screen or a pop-up screen). The notification unit 208 may also send notifications to wearable terminal devices worn by the user. Furthermore, the notification unit 208 may, if necessary, send notifications to medical institutions, schools, workplaces, public services, etc.

[0112] The information acquisition unit 202 may also acquire the status of other users and store it in the status storage area 216.

[0113] The state memory area 216 can store information such as the following as the user's state:

[0114] • Changes in the user's load on walker 1. The change in load may be recorded as a change in the load value, or, for example, as a change in the center of gravity of the load.

[0115] • The user's sleep and wakefulness states. For example, it may be possible to record whether the user is drowsy while using walker 1. It may also be possible to obtain information about the user's sleep when they fall asleep and wake up. Information about the user's sleep, such as when they fall asleep and wake up, may be obtained from a sleep detection device other than walker 1, for example.

[0116] The above-described processes may be executed on any device or on a server device. For example, the walker 1 only needs to be able to execute the sensor value acquisition unit 102. For example, the control unit 100 transmits the sensor values ​​acquired by the sensor value acquisition unit 102 to the terminal device 2. The biometric information calculation unit 104 and the state determination unit 106 may then be executed on the terminal device 2.

[0117] Alternatively, the event determination unit 204, recommendation unit 206, and notification unit 208 may be implemented in the walker 1. In this case, the walker 1 alone can perform the functions shown in Figure 8. When implementing Figure 8 with the walker 1 alone, the information and data stored in the storage 210 can be stored in the walker 1's storage 110.

[0118] Furthermore, the biometric information calculation unit 104, state determination unit 106, event determination unit 204, recommendation unit 206, and notification unit 208 may be implemented by a server device. For example, the walker 1 transmits sensor values ​​to the server device. The server device executes each process based on the received sensor values. The terminal device 2 can then communicate with the server device, for example, using a web browser or a dedicated application, to receive recommendations or notifications.

[0119] [2.4 Example of processing] Below, we will describe some examples of the processing in this embodiment.

[0120] [2.4.1 First Processing Example] As a first example of processing, the process by which the terminal device 2 acquires information will be described. The control unit 200 detects an impact from the walker 1 (step S102; Yes). The impact may be detected by the walker 1 each time it detects a predetermined impact (for example, when an acceleration sensor provided on the rear frame 14 detects an acceleration above a predetermined threshold). Alternatively, the control unit 200 may analyze the sensor values ​​acquired from the walker 1 and detect that an impact has occurred.

[0121] When the control unit 200 detects a predetermined impact, it stores the fact that an impact has been detected as an event in the event storage area 218 (step S102; Yes → step S104).

[0122] Next, when the control unit 200 detects that there has been a change in load (step S106; Yes), it stores the change in load (step S108). A change in load indicates that the user is using the walker 1. The control unit 200 stores the movement and load changes when the user is using the walker 1 in the state storage area 216. The control unit 200 may also detect a movement of the center of gravity of the load as a change in load and store it in the state storage area 216.

[0123] Furthermore, if the load change is uneven or the load change is greater than a predetermined threshold, the control unit 200 may store the load change as an event in the event storage area 218.

[0124] Next, when the control unit 200 acquires biological information, it stores the biological information (step S110; Yes → step S112). The control unit 200 acquires and stores biological information from the walker 1, but it may also acquire biological information from other devices. For example, it may store biological information from a wearable terminal device worn by the user in the biological information storage area 214.

[0125] Furthermore, the control unit 200 may store the biological information in the event storage area 218 as an event based on the biological information value when the biological information exceeds a first threshold or falls below a second threshold.

[0126] Furthermore, when the control unit 200 acquires the status of another user, it stores it as the user's status in the status storage area 216 (step S114; Yes → step S116).

[0127] Furthermore, the control unit 200 may repeatedly execute the process from step S102 until the process is completed (step S118; No → step S102).

[0128] Thus, according to the first processing example, the terminal device 2 can acquire the necessary information from the walker 1 and store it as needed.

[0129] [2.4.2 Second Processing Example] The second processing example will be explained. The second processing example describes a process that provides recommendations as needed.

[0130] First, the control unit 200 may notify emergency contacts when a large impact is detected (step S202; Yes → S204). For example, terminal device 2 stores emergency contacts in advance. Emergency contacts include, for example, family contacts (telephone number, email address, etc.), doctors' contacts, hospitals, fire departments, police, etc. Also, when the walker 1 is used in a facility or hospital, the terminal devices of staff such as nurses, doctors, and caregivers may be designated as contacts, or the management device installed in the nurse station (waiting area) may be designated as a contact.

[0131] For example, if a large impact is detected, it may indicate that the user has fallen, so the control unit 200 will promptly notify staff so that they can respond quickly.

[0132] Furthermore, the control unit 200 may execute step S204 if, after a large impact is detected, the sensor unit 160 can no longer detect the user. For example, if, after a large impact is detected, the control unit 200 may determine that the user's hands have left the walker or that the user has fallen, and may notify the emergency notification recipient.

[0133] Furthermore, the control unit 200 may execute step S204 if, after a large impact is detected, the sensor unit 160 shows no change in the user's load for a predetermined time or the walker 1 does not move for a predetermined time. For example, if the user may have bumped into something and become unable to move, the control unit 200 will send a notification to the emergency notification recipient.

[0134] In this way, the control unit 200 can provide more accurate notifications to staff and others by issuing notifications in two stages. For example, if a user simply bumps the walker 1 while moving, the control unit 200 will not issue a notification. This allows the control unit 200 to suppress excessive notifications.

[0135] Furthermore, the control unit 200 may change the recipient of the notification based on the two-stage detection. For example, when the control unit 200 detects a large impact, it may send a notification from the notification unit 150 of the walker 1. Also, if the user's load is not detected or there is no change in the user's load after a large impact has been detected, the control unit 200 may send a notification to other devices (for example, terminal devices for staff, terminal devices for family members, devices at the nurse station, etc.).

[0136] Furthermore, the notifications in steps S202 and S204 may be performed by the walker 1. For example, if the sensor unit 160 of the walker 1 detects a large impact based on the sensor values ​​it has acquired, it may issue a notification from the notification unit 150 or notify other devices via the communication unit 170. For example, the walker 1 can perform the notification in step S204 even if the terminal device 2 is not powered on or if the walker 1 is unable to communicate with the terminal device 2.

[0137] Next, it is determined whether an impact has been detected more than a predetermined number of times within a predetermined period (step S206). For example, in Figure 11, the control unit 200 determines, as an example, whether an impact of five or more times has been detected within three days. That is, it detects whether the user has come into contact with the rear frame 14 of the walker 1 in a short period of time. Note that detecting five or more impacts within three days is just an example, and the number of days may differ. The control unit 200 determines that an impact has been detected more than or equal to a first threshold number of times within a first number of days.

[0138] The control unit 200 determines whether the user is losing balance while using the walker 1 if it detects five or more impacts within three days. For example, in Figure 11, the control unit 200 determines that the user is losing balance and there is a problem with their walking style if the load transfer is unstable (for example, the center of load moves by more than a predetermined amount, or the displacement of the load exceeds a predetermined amount). Therefore, the control unit 200 selects a point related to "walking style" (step S208; Yes → step S210).

[0139] Next, the control unit 200 determines whether there is an abnormality in the biological information (step S212). If the control unit 200 determines that there is an abnormality in the biological information (for example, heart rate, blood pressure, blood glucose level, etc. are abnormally high above a predetermined threshold, SpO2 is below a predetermined threshold, etc.), it determines that there is a disease as the cause. Therefore, the control unit 200 selects the "examination" point (step S212; Yes → step S214).

[0140] Next, the control unit 200 determines whether the cumulative number of impacts exceeds a second threshold (step S216). If the control unit 200 determines that the user has bumped into the walker 1 more than a certain number of times, even if not over a short period of time, it determines that the walker 1 may not be suitable for the user. Therefore, the control unit 200 selects the "product" point (step S216; Yes → step S218).

[0141] Then, the control unit 200 (recommendation unit 206) displays recommendations based on the selected points (step S220). The recommendation unit 206 may, for example, obtain and present information deemed appropriate from a server device. The recommendation unit 206 may also make recommendations such as displaying sites as needed.

[0142] Here, the recommendation section 206 could consider the following as recommendations for points.

[0143] (1) How to walk The control unit 200 recommends the correct way to walk to the user. For example, the control unit 200 may instruct the user on the tilt of their posture, the direction in which to apply force, or the walking speed. The control unit 200 may also explain the user's walking style with a video or introduce a webpage that describes the correct way to walk.

[0144] (2) Medical examination The control unit 200 provides advice to the user to encourage them to seek medical attention. For example, the control unit 200 may display hospital information or a hospital appointment page to the user. The control unit 200 may also recommend an appropriate medical department based on the information it has determined. Furthermore, the control unit 200 may recommend the use of other devices or supplements.

[0145] (3) Products The control unit 200 provides the user with advice regarding an appropriate walker 1. For example, the control unit 200 may recommend a walker of a different size than the one currently being used (e.g., a larger walker) or a different type of walker.

[0146] (4) Habits The control unit 200 may provide the user with advice regarding habits. For example, the control unit 200 may recommend appropriate times for the user to go to sleep and wake up. The control unit 200 may also provide recommendations regarding the user's living environment. For example, the control unit 200 may advise the user to use the air conditioner or to open and close the curtains. Although the advice regarding habits is explained in steps S244 and S246 of Figure 13, it may also be performed before step S220 in Figure 11. In other words, the control unit 200 may make recommendations based on the user's habits.

[0147] Next, we will explain an example of operation using the display screen shown on terminal device 2. Figure 12(a) is an example of display screen W100 showing recommendations when "Walking Style" and "Products" are selected as points. The control unit 200 displays a message in area R100 as a recommendation on display screen W100. The control unit 200 also displays, as a recommendation for "Walking Style," a button B100 that shows a video on how to walk, and a button B102 that moves to a site introducing recommended walkers.

[0148] Users can view the message displayed in area R100 and take appropriate action according to the recommendations.

[0149] Figure 12(b) is an example of the display screen W110 showing recommendations when "Walking Style" and "Medical Examination" are selected as points. The control unit 200 displays a message in area R110 as a recommendation on the display screen W110. The control unit 200 also displays a button B110 that displays recommendations corresponding to "Walking Style" and a button B112 that moves to a site where you can make a hospital appointment or access medical information.

[0150] Thus, this process makes it possible to provide appropriate recommendations when the user bumps into the walker 1.

[0151] [2.4.3 Third Processing Example] Next, we will explain the third processing example. The third processing example in Figure 13 is a replacement for the second processing example in Figure 11, and the same processes are denoted by the same reference numerals.

[0152] In the second processing example, the trigger was the user bumping into the walker 1, but in the third processing example, the information acquired by the walker 1 is used as the trigger. In other words, in the third processing example, the control unit 200 performs a process of making recommendations based on event information.

[0153] The control unit 200 selects a "walking style" point when it determines that the user's weight shift has not been detected (step S208; Yes → step S210). For example, the control unit 200 selects "walking style" when it finds events such as "weight value imbalance" or "center of gravity imbalance" from the event information included in a predetermined period.

[0154] Here, the control unit 200 may select "walking style" when there are a predetermined number of events related to load or center of gravity within a predetermined period. Alternatively, the control unit 200 may select "walking style" when, for example, there is at least one event related to load or center of gravity on the previous day.

[0155] Similarly, if the control unit 200 detects an abnormality in the user's biological information, it selects the "Examination" point (Step S212; Yes → Step S214). The control unit 200 also determines whether there is another product suitable for the user based on the user's weight shift (shift in center of gravity), etc. Then, if the control unit 200 determines that there is another product suitable based on the user's condition information, biological information, etc., it selects the "Product" point (Step S242; Yes → Step S218).

[0156] Furthermore, the control unit 200 refers to the user's status and, if it determines that there is a problem with the user's lifestyle habits, selects the "habit" point (step S244; Yes → step S246). Then, the control unit 200 displays a recommendation based on the selected point (step S220).

[0157] Here, the first condition below is one example of a condition under which the control unit 200 determines that there is a problem with lifestyle habits, etc. Based on the first condition, the control unit 200 may display a recommendation in step S220.

[0158] (1) The control unit 200 makes a determination based on the user's sleep time as the first condition. For example, if the user's sleep time is short (for example, less than 5 hours of sleep the previous day), the control unit 200 may display a recommendation such as "Let's go to sleep a little earlier." (2) The control unit 200 makes a determination based on the user's daily rhythm, such as the time the user goes to sleep and wakes up, as the first condition. For example, if the user goes to sleep late or wakes up late, the control unit 200 may display a recommendation such as "Try going to sleep a little earlier." Also, if there is variation in the user's time the user goes to sleep and wakes up, the control unit 200 may display a recommendation such as "Try going to sleep at a set time" and "Try waking up at a set time." (3) The first condition is determined based on the number of times the user gets out of bed during sleep (number of times they wake up in the middle of the night). For example, if the user gets out of bed (number of times they wake up in the middle of the night) three or more times in one night, the control unit 200 may display a recommendation such as "Reduce fluid intake before going to bed." The control unit 200 may also display recommendations such as "Adjust the temperature to a suitable level" or "Use bedding that is easy to sleep on" based on the environment of the user's room. (4) The first condition is determined based on the usage status of the walker 1. For example, if the user uses the walker 1 for a short time (for example, less than 10 minutes a day), the control unit 200 may display a recommendation such as "Let's move around a bit more."

[0159] In this way, the control unit 200 can determine whether there are problems with the user's lifestyle habits and daily rhythm based on the first condition and display recommendations.

[0160] The control unit 200 may perform recommendation display by combining multiple conditions. For example, the control unit 200 may perform recommendation display by combining a first condition and a second condition.

[0161] Furthermore, the control unit 200 may combine multiple conditions to make recommendations to the user. For example, the control unit 200 may display recommendations based on sleep duration as the first condition and the usage status of the walker 1 as the second condition.

[0162] For example, if the first condition is that the user's sleep time is shorter than the prescribed time, and the second condition is that the distance traveled with the walker 1 is long or the time spent using the walker 1 is long, the control unit 200 may display a warning recommendation such as "Take frequent breaks." This is because the control unit 200 determines that the user's risk of falling increases under these conditions.

[0163] Furthermore, the control unit 200 may also display a similar warning recommendation when, as a first condition, the user's medication status, or as a second condition, when the distance traveled by the walker 1 is long or the time spent using the walker 1 is long. For example, if the user is taking medication that causes drowsiness or dizziness, the control unit 200 will determine that the risk of falling increases when using the walker 1.

[0164] Thus, the third processing example can make recommendations based on event information, regardless of whether the user initially collided with walker 1 or not.

[0165] Figure 14(a) shows an example of a display screen W200 on the display unit 250 of the terminal device 2, where the control unit 200 (recommendation unit 206) displays recommendations. The control unit 200 displays a message in area R200 of the display screen W200. The display screen W200 also displays a button B200 for transitioning to a page displaying information for improving lifestyle habits, and a button B202 that allows transitioning to a page providing appointment scheduling or medical information to encourage medical consultation.

[0166] Figure 14(b) is a diagram showing an example of a display screen W210 on the display unit 250 of the terminal device 2, where the control unit 200 has made recommendations based on biometric information. The control unit 200 displays a message in area R210 of the display screen W210. The control unit 200 also displays a graph showing the transition of biometric information (e.g., heart rate) in area R220 of the display screen W210. The graph shows, for example, the transition over the past day. The graph may also show, for example, the past average, or it may overlay other biometric information.

[0167] Figure 15 shows an example of a display screen W220 that displays a notification when the walker 1 detects a strong impact. The display screen W220 may be a terminal device 2 used by the user, or it may be a terminal device used by a family member, such as a staff member.

[0168] A pop-up display is shown in area R220 at the forefront of the display screen W220. In this way, the control unit 200 can notify users, staff, etc., that a strong impact has been detected via the pop-up display, even when the terminal device 2 is in use or on standby. The pop-up display may also show, for example, a call button B222. The call button B222 may have the phone number of the walker 1 user registered. This allows staff, etc., to immediately check the user's status by selecting the call button B222.

[0169] [2.5 Effects] Thus, according to this embodiment, by using the walker 1, it is possible to suggest an appropriate walker to the user. Furthermore, according to this embodiment, the user's condition can be appropriately understood by obtaining information through the walker 1.

[0170] For example, by placing sensor units (e.g., piezoelectric sensors) on both sides of the gripping part 20, which is the grip of the walker 1, and having the terminal device 2 analyze the acquired data using software, it is possible to obtain biometric information such as heart rate, blood pressure, and blood glucose levels.

[0171] This allows, for example, when a user walks using walker 1, feedback on changes in heart rate and blood pressure can be provided to determine whether their walking style is strenuous or appropriate and not strenuous.

[0172] Furthermore, because the user of the walker 1 uses it continuously every day, it is possible to understand changes in biometric information over a longer period of time. For example, by comparing the biometric information acquired continuously every day with the biometric information values ​​from health checkups, it becomes possible to encourage the user to maintain their health.

[0173] [3. Third Embodiment] A third embodiment will now be described. The system T of the third embodiment is shown in Figure 16. System T is an embodiment in which multiple walkers 1 and / or terminal devices 2 are connected to a server device 3 via a network NW, compared to the system S of the second embodiment.

[0174] Server device 3 acquires various information from the communication-enabled terminal device 2 and the walker 1. Server device 3 is, for example, a server device like the one shown below.

[0175] • A server device that manages medical information connected to medical institutions such as hospitals, clinics, and pharmacies. • Server devices used by local governments and other organizations to manage citizen information.

[0176] Server device 3 acquires user information via walker 1 or terminal device 2. User information includes information that can be stored as shown in Figure 8, such as the user's sensor values, biometric information, and other information indicating the user's state (e.g., information related to sleep, information related to daily rhythm, etc.), which is received and managed.

[0177] Furthermore, the server device 3 may acquire information from devices other than the walker 1. For example, the server device may receive biometric information and the user's status from various devices such as thermometers, scales, blood pressure monitors, and sleep monitors, either on its own or via the terminal device 2.

[0178] Server device 3 can provide physicians with biometric information and information acquired by other devices (sensors) via the network NW. Physicians can then access information about users from server device 3, which can be used for home healthcare.

[0179] Furthermore, by providing information to local governments and other organizations, the server device 3 can help them understand the frequency of use of welfare equipment and whether it is being used in a way that puts a strain on the equipment, thereby contributing to the appropriate use of welfare equipment.

[0180] [4. Fourth Embodiment] A fourth embodiment will now be described. In the fourth embodiment, the walker 1 and the terminal device 2 work together with optional external devices and external services to provide various notifications and instructions for use to the user. This embodiment is, for example, an embodiment in which an optional external device is connected to the walker 1 described in the second embodiment, or in which communication is linked with an external service. Only the differences from the configurations of the first and second embodiments will be described below.

[0181] [4.1 First Processing Example] The first processing example describes the process when an external device is connected to the walker 1. For example, an LED light or the like may be connected to the second lateral frame 24 or the lower surface of the second connecting member 34 of the walker 1. The LED light may be added later or built in beforehand.

[0182] The control unit 200 acquires illuminance from, for example, an illuminance sensor (which may be installed on the walker 1, or on the terminal device 2, or it may be connected to and used with an illuminance sensor at the user's location). When the control unit 200 determines that the illuminance is below a predetermined threshold and the surrounding environment is dark, the control unit 200 may display a notification on the display unit 250 saying "Please turn on the light." Alternatively, the control unit 100 or the control unit 200 may perform the process of turning on the LED light installed on the walker 1.

[0183] In particular, when the user gets out of bed and uses walker 1, the LED light turns on according to the brightness of the room. This allows the user to safely use walker 1 to turn on the lights in the entire room.

[0184] Furthermore, the walker 1 may have a human presence sensor installed in front of it as an external device. When the control unit 200 determines that a person is nearby based on the human presence sensor, it may issue a warning from the notification unit 150. For example, when the human presence sensor detects a person approaching, the control unit 200 may output music or a warning sound from the notification unit 150.

[0185] Furthermore, the walker 1 may be equipped with a camera device as an external device. The camera device may, for example, photograph the walking style and movements of the user using the walker 1. The control unit 200 may analyze whether the user's walking style is appropriate based on the images captured by the camera device and output advice from the notification unit 150. For example, if the user's body is leaning to the left or right, the control unit 200 may notify the user, "Your body is leaning. Straighten it."

[0186] Furthermore, the walker 1 may be connected to smart home appliances. For example, when a user uses the walker 1, if the illuminance detected by the illuminance sensor provided on the walker 1 falls below a predetermined threshold and the control unit 200 determines that the surrounding environment is dark, the control unit 200 may turn on the LED light provided on the walker 1. In addition, after turning on the LED light on the walker 1, the control unit 200 may further turn on the lights that illuminate the entire room. By linking the walker 1 with smart home appliances (e.g., lighting devices, air conditioners, toilets, etc.), it becomes possible to assist the user in their next action. For example, when a user moves to the toilet using the walker 1, the walker 1 or terminal device 2 may send a control signal to automatically open the toilet seat lid. The user can move directly from the walker 1 to the toilet seat without having to open the toilet seat lid, which not only improves convenience but also contributes to safety by preventing the user from falling.

[0187] [4.2 Second Processing Example] The second processing example is a process in which the walker 1 or terminal device 2 communicates with an external service to obtain information. For example, the control unit 100 may obtain the time from a time server via the communication unit 170. In this case, if it is late at night, the control unit 100 may notify the user, "Isn't it time to go to bed?" Also, if the LED light described in the first processing example is provided, the control unit 100 may automatically turn on the light when it becomes nighttime.

[0188] Furthermore, the walker 1 may obtain weather information from a server that provides weather forecasts. For example, the control unit 100 may obtain a weather forecast from the server as information about the current weather based on the location and time information of the walker 1. The control unit 100 may then issue a warning, for example, if rain is forecast, such as "Please check if the anti-slip rubber is worn down."

[0189] These processes may be implemented in the walker 1 or in the terminal device 2. When implemented in the terminal device 2, the control unit 200 executes each process and sends control signals to the walker 1 as needed.

[0190] Thus, according to this embodiment, the convenience of the walker 1 can be further enhanced when an external device is connected to it. Furthermore, by having the walker 1 or terminal device 2 acquire information from an external service provided by a server, it becomes possible to provide appropriate recommendations to the user.

[0191] [5. Variant] This disclosure is not limited to the embodiments described above, and various modifications are possible. In other words, embodiments obtained by combining technical means that are appropriately modified within the scope of the gist of this disclosure are also included in the technical scope of this disclosure.

[0192] Furthermore, although the embodiments described above are explained separately for the sake of explanation, they can be combined and implemented to the extent possible. In addition, we intend to obtain rights to any of the technologies described in this specification through amendments or divisional applications.

[0193] Furthermore, in each embodiment, the program that operates in each device is a program that controls the CPU and other components (a program that makes the computer function) in order to realize the functions of the embodiments described above. The information handled by these devices is temporarily stored in a temporary storage device (for example, RAM) during processing, and then stored in various ROMs or HDDs, and read, modified, and written by the CPU as needed.

[0194] Here, the recording medium used to store the program may be any of the following: semiconductor media (e.g., ROM or non-volatile memory card), optical recording medium or magneto-optical recording medium (e.g., DVD (Digital Versatile Disc), CD (Compact Disc), BD, etc.), magnetic recording medium (e.g., magnetic tape, flexible disk, etc.).

[0195] Furthermore, when distributing the program to the market, it can be stored on a portable recording medium and distributed, or transferred to a server computer connected via a network such as the Internet. In this case, the storage device of the server device is, of course, also included in this disclosure.

[0196] Furthermore, the data mentioned above may not be stored within the device itself, but rather stored on an external device and retrieved as needed. For example, the data may be stored on a NAS (Network Attached Storage) or on the cloud.

[0197] Furthermore, the scope of this disclosure is not limited to the configurations explicitly described in the specification, but also includes combinations of the technologies disclosed herein. While the configurations for which patent protection is sought are described in the attached claims, there is no intention to exclude them from the technical scope simply because they are not described in the claims.

[0198] Furthermore, the phrases "in the case of..." and "when..." in the above-mentioned specification are explained as examples only, and do not represent a configuration limited to those described. Even for configurations other than those described, we disclose information that would be obvious to a person skilled in the art, and we intend to acquire rights to such information.

[0199] Furthermore, the descriptions of the processes and data flows described in the specification are not limited to the order in which they are described. For example, configurations in which parts of the process are deleted or the order is rearranged are also disclosed, and the company intends to acquire rights to them. [Explanation of Symbols]
