DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Note that the embodiment described below is one embodiment of the present disclosure, and the contents of the present disclosure should not be interpreted as being limited based on the following description.

[0009] Walkers are known as one of the devices that assist users in walking. There are several types of walkers, and among them, pick-up type walkers (fixed type walkers) in which the user lifts the walker body and moves forward are known. In the following, pick-up type walkers will be simply referred to as walkers.

[0010] The method of walking using a walker is generally explained on the assumption that the user will step forward with a straight foot. However, when such a walker is used by a user with hemiplegia, for example, the user is simply unable to step forward with a straight foot. Similarly, when such a walker is used by an elderly user with stiff joints or a user with some kind of illness, the user is also unable to step forward with a straight foot.

[0011] Therefore, when a user with hemiplegia uses a walker, the user often supports the walker and uses the body to rotate the paralyzed side and step forward. When doing so, the user moves the foot in a rotating motion outward from the body, but with a walker designed for normal walking, there is a problem in that the rotating foot is likely to hit the leg (rear leg) that supports the walker.

[0012] This is because walkers are generally designed to provide as much space as possible around the user's legs, assuming normal walking patterns. However, pick-up walkers are often used indoors, and therefore are designed not to be wider than necessary, as smaller external dimensions are easier to handle.

[0013] Therefore, as mentioned above, in the case of a user with hemiplegia, the foot that is moved outward from the body when walking is likely to hit the leg of the walker, making the walker difficult to use.

[0014] In this manner, in the following embodiment, a walking device based on the unprecedented idea of ​​proposing a walking device that is easy to use even for hemiplegic users will be described.

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

[0016] The user is a person who uses a walker. The user is not limited to sick people or people requiring care, but includes healthy people. The user is not limited to adults and elderly people, but also includes children. The walker in this embodiment is most effective when used by a user who walks with his or her feet turned outward, such as a user with hemiplegia. The walker is also effective when the user has an injury to one foot.

[0017] In addition, the term "staff" includes medical staff at the hospital where the user is hospitalized and staff at the facility where the user resides. In addition, in the case of a user's home, the term "staff" includes family members who take care of the user.

[0018] [1. First embodiment] [1.1 Overall structure] Fig. 1 is a perspective external view showing the entire walker 1. Fig. 2 is a side external view of the walker 1 as seen from the left, showing the left side frame 10.

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

[0020] The side frame 10 has a front frame 12 which extends vertically and constitutes the front legs of the walker 1, a rear frame 14 which constitutes the rear legs of the walker 1, and an upper frame 16 which connects the upper end of the front frame 12 with the upper end of the rear frame 14.

[0021] Furthermore, in order to reinforce the side frame 10, one or more frames may be disposed approximately parallel to the upper frame 16. In this embodiment, the side frame 10 has a first horizontal frame 22 and a second horizontal frame 24 at the middle position in the up-down direction.

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

[0023] In addition, the connection portion between the front frame 12 and the upper frame 16 may be bent to draw an arc as shown in Figures 1 and 2. In addition, the connection portion between the front frame 12 and the upper frame 16 may be connected to form a corner, or straight members may be connected to each other.

[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, a cushion, or the like. The gripping portion 20 is a portion that the user grips when walking using the walker 1. The gripping portion 20 is preferably shaped to make it easy for the user to grip the upper frame 16. The gripping portion 20 may be provided so as to be wrapped around the upper frame 16. Also, instead of the gripping portion 20, the upper frame 16 may be shaped to be easy for the user to grip.

[0025] The first horizontal frame 22 is fixed to the front frame 12 and the rear frame 14. The first horizontal frame 22 may be connected to the front frame 12 and the rear frame 14 by welding, or may be fixed by a fixing member such as a screw. Furthermore, the first horizontal frame 22 may be formed integrally with the front frame 12 and the rear frame 14.

[0026] Moreover, it is preferable that the first horizontal frame 22 is connected to the front frame 12 and the rear frame 14 at a substantially right angle. Therefore, the first horizontal frame 22 may be gently bent in a dogleg shape near the center to match the inclination of the front frame 12 and the rear frame 14. The first horizontal frame 22 may be provided near the upper side of the side frame 10 in the up-down direction.

[0027] In addition, the second horizontal frame 24 is provided between the front frame 12 and the rear frame 14 below the first horizontal frame 22 in order to reinforce the side frame 10 .

[0028] The second horizontal frame 24 may be fixed to the front frame 12 and the rear frame 14 by any method. In this embodiment, for example, the end portion of the second horizontal frame 24 is curved to have a shape parallel to the front frame 12 and the rear frame 14. For example, the second horizontal frame 24 has a substantially U-shape in side view.

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

[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 a pipe like the side frame 10. Also, the first connecting member 32 and the second connecting member 34 may be made of a material different from that of the side frame 10.

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

[0032] The first connecting member 32 may have a locking mechanism. For example, the user locks the first connecting member 32 in an unfolded state (straight state) during use. When folding, the user releases the locking mechanism, so that the first connecting member 32 becomes foldable.

[0033] The second connecting member 34 is foldable, but may not have a locking mechanism. For example, when the first connecting member 32 is locked by the locking mechanism of the first connecting member 32, the second connecting member 34 is maintained in an unfolded state (straight state). When the locking mechanism of the first connecting member 32 is released, the second connecting member 34 and the first connecting member 32 are also foldable together.

[0034] Further, the side frame 10 may be provided with a non-slip member made of rubber, etc., at the lower end. For example, the front frame 12 may be provided with a non-slip member 12A at the lower end, and the rear frame 14 may be provided with a non-slip member 14A at the lower end.

[0035] The side frame 10 may also have an adjustment mechanism for adjusting it so that it can expand and contract 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 may be changed by using the adjustment mechanisms 12B and 14B.

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

[0037] 3(a) explains the position of the rear frame 14 of this embodiment. The walker 1 of this embodiment is characterized in that the lower end of the rear frame 14 is located further forward than in conventional walkers.

[0038] The dashed imaginary line 18 in Fig. 3(a) is an imaginary line showing the position of the conventional rear frame. In contrast, the rear frame 14 of the walker 1 in this embodiment is characterized in that the lower end is located forward compared to the conventional position.

[0039] As a result, when comparing angle R1, which is the first angle formed between the front frame 12 and the upper frame 16, and angle R2, which is the second angle formed between 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 a horizontal plane FL, the angle R3 formed by the front frame 12 and the horizontal plane FL is compared with the angle R4 formed by the rear frame 14 and the horizontal plane FL, and R4 is larger.

[0041] In the conventional walker 1, the position of the rear frame 14 is the position of the imaginary line 18. For example, the conventional walker 1 has an isosceles trapezoidal shape in a side view, and the angle formed between the upper frame 16 and the front frame 12 is the same as the angle formed between the upper frame 16 and the rear frame 14. Therefore, the angle formed between the horizontal plane FL and the front frame 12, and the angle formed between the horizontal plane FL and the rear frame 14 are also the same.

[0042] This causes a problem that the user's feet may hit the rear frame when walking using the walker 1. In the walker 1 of the present embodiment, position P1 of the bottom end of the rear frame 14 is moved forward from position P2 of the bottom end of the imaginary line 18 of the conventional rear frame. By moving P1 forward from P2, it becomes possible to prevent the user's feet from hitting the rear frame 14 even when walking using the walker 1.

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

[0044] As an example of explanation, the walker 1 in FIG. 3(b) will be explained using specific numerical values. For example, in FIG. 3(b), the angle R4 is set to 90 degrees, whereas the angle in the conventional product was 84 degrees. Also, for example, the angle R2 is set to 92.5 degrees, whereas the angle in the conventional product was 96 degrees. As a result, the distance W1 between P1, where the lower end of the rear frame 14 of this embodiment is located, and the position P2 of the lower end of the virtual line 18 indicating the conventional rear frame, is approximately 6 cm. That is, in the walker 1 of this embodiment, the lower end of the rear frame 14 is positioned closer to the front by the distance W1 than in the conventional walker.

[0045] In this case, R1 may be left at the angle (96 degrees) of the conventional product, and an inclination may be provided to the upper frame 16. For example, the upper frame of the conventional product is parallel to the horizontal plane FL, but the upper frame 16 of this embodiment is inclined upward by 2.5 degrees (angle R5 in FIG. 3(b)) from the rear to the front.

[0046] Note that these numerical values ​​are merely examples and are not limited to these numerical values. For example, the angle R4 may be set to any value as long as it satisfies the following relationship. R3 < R4 ≦ 90 degrees

[0047] Moreover, angle R2 may be any angle smaller than angle R1. For example, the difference between angle R1 and angle R2 is preferably 3 degrees or more and 6 degrees or less. Moreover, the difference between angle R1 and angle R2 is preferably in the range from the predetermined angle to angle R1-90 degrees. For example, if the predetermined angle is 3 degrees, the difference between angle R1 and angle R2 is preferably 3 degrees or more and angle R1-90 degrees or less. That is, if the predetermined angle is 3 degrees, angles R1 and R2 have the following relational expression. 3 degrees≦R1-R2≦R1-90 degrees

[0048] In this way, the minimum angle of the angle R2 may be set so that the rear frame 14 is perpendicular to the installation surface (for example, approximately 90 degrees). For example, some specific angles are as follows: · When angle R1 is 96 degrees, the angle difference between angle R1 and angle R2 is 3 to 6 degrees, and angle R2 is 90 to 93 degrees. · When angle R1 is 100 degrees, the angle difference between angle R1 and angle R2 is 3 degrees to 10 degrees, and angle R2 is 90 degrees to 97 degrees. · When angle R1 is 105 degrees, the angle difference between angle R1 and angle R2 is 3 degrees to 15 degrees, and angle R2 is 90 degrees to 102 degrees.

[0049] Furthermore, 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 (for example, approximately 90 degrees) to the installation surface.

[0050] Furthermore, position P1 of the lower end of the rear frame 14 may be located forward of conventional position P2. In other words, P1 may be located between a position from the rear end of the upper frame 16 that is approximately perpendicular to the horizontal plane FL, which is the installation surface, and P2, which is the conventional position of the lower end of the 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 ranges of manufacturing errors, assembly errors, etc.

[0051] In this embodiment, the distance W1 is set to 6 cm, but it is preferable that the distance W1 be within a range of 2 cm to 6 cm so that the position of the lower end of the rear frame 14 is positioned closer to the front.

[0052] In addition, in this embodiment, the inclination of the upper frame 16 has been described as increasing at angle R5 of 2.5 degrees from the rear to the front, but angle R5 may preferably be within the range of 1.5 degrees to 6 degrees.

[0053] In the above example, the rear frame 14 is positioned forward by providing a difference between the angles R1 and R2, but this may be achieved by other methods. Fig. 3(c) is a diagram showing a state in which the length of the front frame 12 is extended.

[0054] For example, as shown in Fig. 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 in advance, or an attachment 12E may be provided as shown in Fig. 3(c).

[0055] As a result, the lower end of the rear frame 14 of the walker 1 is located further forward than in conventional walkers. Also, the upper frame 16 is inclined upward from the rear to the front.

[0056] [1.3 Example of operation] 4 is a schematic diagram illustrating the position of the feet and the position of the walker 1. Positions PF1, PF2, PR1, and PR2 are shown as locations where the walker 1 of this embodiment is located. 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, as the positions of the rear frames of a conventional walker 1, the left side is shown as position PR3, and the right side is shown as position PR4.

[0057] Here, the user's left foot is at position F10 and the right foot is at position F12. The user puts one foot forward after supporting the weight of the user on the walker 1. In Fig. 4, the user moves from position F12 to position F14 by putting the right foot forward.

[0058] Here, the user's right foot moves along the path indicated by the dashed line V10. At this time, in a conventional walker, the rear frame is at position PR4, so the user's right foot hits it. In contrast, in this embodiment, the rear frame 14 is at position PR2, so the user's right foot can move without hitting it.

[0059] [1.4 Effects] Thus, according to the walker 1 of this embodiment, the lower end position of the rear frame is located further forward than in conventional walkers. This allows the user to move comfortably even when walking using the walker 1, without the feet hitting the rear frame 14. Furthermore, when the user transfers from the walker 1 to another device (e.g., a bed, a chair, a toilet seat, a lift, etc.), the user can transfer without the feet hitting the rear frame 14. Similarly, when the user transfers from another device to the walker 1, the user can transfer without the feet hitting the rear frame 14.

[0060] Furthermore, according to the walking aid 1 of this embodiment, the upper frame 16 has a gentle incline that rises from the rear to the front. The incline makes it easier for the user to support the user's body.

[0061] [2. Second embodiment] In the second embodiment, a system S that utilizes the walking aid 1 described in the first embodiment will be described.

[0062] Walkers have been used to move users, but their function was simply to assist with movement. Now, since walkers are used every day, there is a demand for them to go beyond being a simple tool for moving around and function as a device for acquiring information about the user's condition.

[0063] It is also known that users who use walkers are at higher risk of falling than those who do not. Therefore, it is desirable to reduce the risk of users falling and to promptly notify staff etc. if a user does fall.

[0064] In order to solve such problems, a system S that uses a walker 1 and a terminal device 2 that can communicate with the walker 1 will be described in the following embodiment.

[0065] [2.1 Overall structure] 5 is a diagram showing an overview of a system S including a walking unit 1 and a terminal device 2. The walking unit 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 a user, and may be, for example, an information processing device such as a smartphone, a tablet, or a computer.

[0066] [2.2 Hardware configuration] Fig. 6 is a diagram for explaining 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 Fig. 6. The control device is a device that is built into the walker 1 or is externally attached. Below, the control device in Fig. 6 will be explained as a function of the walker 1.

[0067] [2.2.1 Common Configuration] Of the individual devices, the control unit, storage, ROM, RAM, and communication unit will be described below.

[0068] The control unit (e.g., control unit 100, control unit 200) is a functional unit for controlling each device as a whole. 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 (e.g., storage 110, storage 210) is a non-volatile storage device capable of storing programs and data. For example, it may be configured as a storage device using an HDD (Hard Disk Drive) or a semiconductor memory. Furthermore, the storage may be an externally connectable storage device or storage medium, and may be configured as a USB memory, a CD-ROM drive, or a BD-drive. Furthermore, the storage may be, for example, a storage area on the cloud.

[0070] The ROM (for example, the ROM 120 and the ROM 220) is a non-volatile memory that can retain programs and data even when the power is turned off. The ROM may store, for example, firmware for each device, initial applications, and the like.

[0071] RAM (e.g., RAM 130, RAM 230) is a main memory that is used mainly by the control unit of each device when executing processing. RAM is a rewritable memory that temporarily holds data including the storage of each device, programs read from the ROM of each device, and execution results.

[0072] The communication unit (e.g., communication unit 170, communication unit 270) is a communication interface that communicates with other devices. For example, it may be a network interface that can provide a wired connection or a wireless connection. In this embodiment, communication with other devices is possible via a network NW. The communication unit may also provide a function that allows connection to a mobile network (LTE (Long Term Evolution) / 4G / 5G / 6G).

[0073] [2.2.2 Walkers] As shown in FIG. 6, the walking unit 1 has a control unit 100, a storage 110 as a memory unit, 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 state and action of the user. For example, the sensor unit 160 can detect a load using a load sensor, detect a potential using a potential sensor, and detect a blood flow using an optical sensor.

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

[0076] When using the walker 1, the user grips the grip unit 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 based on the type of sensor device.

[0077] The value (sensor value) detected by the sensor unit 160 is output to the control unit 100. The control unit 100 can obtain the user's motion and biological information based on the sensor value.

[0078] The sensor unit 160 may also be provided elsewhere. For example, the side frame 10 may have an acceleration sensor or impact sensor built in at any position. For example, an acceleration sensor (impact sensor) is built in the rear frame 14. If the user's foot hits the rear frame 14, the hit can be detected.

[0079] Sensor unit 160 may also be configured with other devices. For example, a sensor device may be connected as an option to walker 1. For example, walker 1 may be provided with a separate heart rate sensor.

[0080] Furthermore, the sensor unit 160 may detect the state of the walker 1. For example, one or more acceleration sensors are built into the walker 1. The control unit 100 outputs a sensor value output from the acceleration sensor to the control unit 100. The control unit 100 may determine the walking style, number of falls, etc. of the user based on the received sensor value.

[0081] Furthermore, the sensor unit 160 may obtain a sensor value from the terminal device 2 connected via the communication unit 170. Furthermore, the walker 1 may obtain a sleep state from another device (for example, a sleep determination device).

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

[0083] The notification unit 150 may also notify by light, vibration, or the like other than sound. The notification unit 150 may also notify other devices. For example, when a problem occurs with the user, the notification unit 150 may notify the terminal device 2. The notification unit 150 may also notify, for example, the state of the walker 1 (for example, the power state or a state indicating whether the user is using the walker 1 correctly).

[0084] 2.2.3 Terminal Equipment As shown in FIG. 6, the terminal device 2 includes a control unit 200, a storage 210 as a memory unit, 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 with which a user operates the terminal device 2. The operation unit 240 may be realized by a hardware switch or a software switch. For example, a touch panel integrated with a display device may be used to realize software keys as the operation unit. The operation unit 240 may also be configured by an external device. For example, the terminal device 2 may use an operation device (e.g., a keyboard, etc.) connected to an interface such as a USB.

[0086] The display unit 250 is a device capable of displaying various information and an execution screen. The display unit 250 may be a device capable of displaying information such as a liquid crystal display or an organic EL display, or may use a light-emitting element such as an LED. For example, the display unit 250 may display the power state or an error state of the terminal device 2 depending on the lighting state of the LED. The display unit 250 may also be configured by an external device. For example, the terminal device 2 may use a display device connected to a terminal capable of outputting video such as HDMI (registered trademark) or DVI.

[0087] The above-mentioned functional configuration is an example, and functions not shown in the figure may be provided or omitted as necessary. For example, the walker 1 may have an operation unit and a display unit. In addition, the walker 1 may be operated and notified of necessary information via the terminal device 2.

[0088] Furthermore, the terminal device 2 may notify or display other devices. For example, the terminal device 2 may transmit necessary information to other devices via the communication unit 270 by email or the like.

[0089] [2.3 Software configuration] Next, the software configuration will be described with reference to Fig. 8. In the walking device 1, a sensor value acquisition unit 102, a biological information calculation unit 104, and a state determination unit 106 are realized by the control unit 100 executing a program stored in the storage unit.

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

[0091] The bioinformation calculation unit 104 calculates a bioinformation value as a value related to the bioinformation of the user based on the sensor value acquired by the sensor value acquisition unit 102. Here, the bioinformation calculated by the bioinformation calculation unit 104 is, for example, a value related to the user's heart rate, body temperature, amount of sweat, SpO2, blood pressure, blood sugar, etc. The bioinformation calculation unit 104 uses a sensor value acquired from a sensor unit 160 capable of calculating bioinformation. For example, when the bioinformation calculation unit 104 calculates the heart rate of the user, the sensor unit 160 is a sensor that operates as a potential sensor. Also, when the bioinformation calculation unit 104 calculates the sweat of the user, the sensor unit 160 is a sensor that can detect the amount of moisture.

[0092] The mechanism by which the biometric information calculation unit 104 calculates the biometric information based on the sensor value output by the sensor unit 160 may utilize any known technology available at the time of filing of any of the applications, and detailed description thereof will be omitted.

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

[0094] The state determination unit 106 determines the state of the user other than the biological information from the sensor value 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 use of the walker 1 is started or the time when the use is ended. The state determination unit 106 may also determine, for example, that the user has fallen based on a change in the load value output from the sensor unit 160.

[0095] The user's status determined by the status determination unit 106 is transmitted to the terminal device 2 via the communication unit 170.

[0096] In the terminal device 2, an information acquisition unit 202, an event determination unit 204, a recommendation unit 206, and a notification unit 208 are realized by the control unit 200 executing a program stored in the storage unit.

[0097] The information acquisition unit 202 acquires information from the walker 1 via the communication unit 270. The information acquisition unit 202 determines the state of the user based on the acquired information and stores the acquired information. For example, the information acquisition unit 202 can acquire bio-information, bio-information values, sensor values ​​output by the sensor unit 160, and the state of the user from the walker 1 via the communication unit 270.

[0098] The information acquiring unit 202 may also acquire other information. For example, information about the user using the walker 1 (e.g., a user ID, a user name, disease information, etc.) may be acquired from the walker 1, or the position of the walker 1 may be acquired.

[0099] Then, the information acquiring unit 202 stores the acquired sensor values ​​in chronological order in the sensor value storage area 212. The information acquiring unit 202 also stores the received biometric information in the biometric information storage area 214.

[0100] 9(a) is an example of biometric information stored in the user's biometric information storage area 214. Referring to FIG. 9(a), the biometric information storage area 214 stores, for each user, a 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, the biological information can be calculated or acquired at a predetermined time interval. The timing of calculating the biological information may vary depending on the type of biological information. For example, in FIG. 9(a), the heart rate is calculated every 20 seconds, while the body temperature and SpO2 are calculated every minute.

[0102] The timing for calculating these pieces of biometric information may be configurable or may be determined in advance.

[0103] The event determination unit 204 determines an event that has occurred to a user, and stores the event in the event storage area 218 .

[0104] 9(b) shows an example of the data configuration of an event stored in the event storage area 218. The event is stored in association with the event occurrence date and time and the event type (contents).

[0105] For example, the following events are considered as examples of events that the event determination unit 204 determines.

[0106] Collision. This is an event that 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 is on the "right" or "left" side. The event determination unit 204 may also store a more precise position on the rear frame 14 and the strength of the impact when the foot hits.

[0107] Load bias: This is an event that occurs when the load of the user is biased to a predetermined threshold or more. For example, when the difference in the load values ​​of the left and right gripping parts 20 becomes a predetermined value or more, this is stored as an event.

[0108] Abnormality in bioinformation value. A first threshold value, which is the upper limit, and a second threshold value, which is the lower limit, are set in advance for each bioinformation value. Then, when the bioinformation value becomes equal to or greater than (or less than) the predetermined threshold value, it is stored as an event. For example, a user sets the first threshold value for heart rate to "130" and the second threshold value to "50". When the heart rate becomes equal to or greater than 130, the event determination unit 204 determines that it is an event and stores it.

[0109] The types of these events may be stored together with their levels and values. For example, the event determination unit 204 may store the level based on the magnitude of the collision or the magnitude of the load imbalance. For example, when the heart rate is high, the event determination unit 204 may store the heart rate together with "heart rate (high)."

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

[0111] The notification unit 208 issues a notification based on the information acquired by the information acquisition unit 202 or the event determined by the event determination unit 204. The notification unit 208 may, for example, display a notification equivalent to the notification on the display unit 250 of the terminal device 2 (for example, displaying an event screen or a pop-up screen). The notification unit 208 may also transmit a notification to a wearable terminal device worn by the user. The notification unit 208 may also issue a notification to a medical institution, a school, a workplace, a public service, or the like, as necessary.

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

[0113] The status storage area 216 can store, for example, the following information as the user's status:

[0114] Changes in the load of the user on the walker 1. The changes in the load may be stored as a change in the load value as is, or, for example, a change in the center of gravity of the load may be stored.

[0115] The user's sleep state and wakefulness state. For example, it may be stored whether the user is in a drowsy state while using the walker 1. Also, information regarding the user's sleep when he or she falls asleep and wakes up may be acquired. Information regarding the user's sleep, such as when he or she falls asleep and wakes up, may be acquired, for example, from a sleep determination device other than the walker 1.

[0116] The above-mentioned processes may be executed by any device or may be executed by a server device. For example, the walking device 1 may be executed by the sensor value acquisition unit 102. For example, the control unit 100 transmits the sensor value acquired by the sensor value acquisition unit 102 to the terminal device 2. The bioinformation calculation unit 104 and the state determination unit 106 may be executed by the terminal device 2.

[0117] Also, the event determination unit 204, recommendation unit 206, and notification unit 208 may be realized by the walker 1. In this case, the walker 1 alone can execute the functions shown in Fig. 8. When the walker 1 alone realizes Fig. 8, the information and data stored in storage 210 may be stored in storage 110 of the walker 1.

[0118] Also, the bioinformation calculation unit 104, the state determination unit 106, the event determination unit 204, the recommendation unit 206, and the notification unit 208 may be realized by a server device. For example, the walker 1 transmits a sensor value to the server device. The server device executes each process based on the received sensor value. Then, the terminal device 2 can receive, for example, recommendations or notifications by communicating with the server device using, for example, a web browser or a dedicated application.

[0119] [2.4 Processing example] Below, some examples of the processing of this embodiment will be described.

[0120] [2.4.1 First processing example] As a first processing example, a process in which the terminal device 2 acquires information will be described. The control unit 200 detects an impact from the walker 1 (step S102; Yes). For example, the walker 1 may notify the occurrence of an impact each time it detects a predetermined impact (for example, an acceleration sensor provided on the rear frame 14 detects acceleration equal to or greater than a predetermined threshold). The control unit 200 may also analyze a sensor value acquired from the walker 1 to detect the occurrence of an impact.

[0121] When the control unit 200 detects a predetermined impact, it stores the detection of the impact 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 the load (step S106; Yes), it stores the change in the load (step S108). A change in the load means that the user is using the walker 1. The control unit 200 stores the movement and change in the load when the user is using the walker 1 in the state memory area 216. The control unit 200 may also detect a shift in the center of gravity of the load as a change in the load, and store this in the state memory area 216.

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

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

[0125] Furthermore, when the biological information becomes equal to or greater than the first threshold value, or becomes equal to or less than the second threshold value, the control unit 200 may store in the event storage area 218 an event based on the biological information value.

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

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

[0128] In this way, according to the first processing example, the terminal device 2 can obtain necessary information from the walking unit 1 and store it as necessary.

[0129] [2.4.2 Second processing example] A second processing example will be described. In the second processing example, a process of making recommendations as necessary will be described.

[0130] First, when a large impact is detected, the control unit 200 may send a notification to an emergency notification destination (step S202; Yes → S204). For example, the terminal device 2 stores a notification destination in advance in the event of an emergency. The notification destination in the event of an emergency is, for example, contact information for family members (telephone number, email address, etc.), contact information for a doctor, a hospital, a fire department, a police department, etc. Furthermore, when the walker 1 is used in a facility or hospital, the notification destination may be a terminal device of a staff member such as a nurse, a doctor, or an assistant, or a management device provided in a nurse's station (waiting area).

[0131] For example, if a large impact is detected, it is possible that the user has fallen, and therefore the control unit 200 promptly notifies staff or the like so that they can respond promptly.

[0132] Furthermore, the control unit 200 may execute step S204 when the user cannot be detected by the sensor unit 160 after a large impact is detected. For example, when the weight of the user is no longer detected by the sensor unit 160 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 destination.

[0133] Furthermore, the control unit 200 may execute step S204 when the sensor unit 160 detects no change in the load of the user for a predetermined period of time or when the walker 1 does not move for a predetermined period of time after a large impact is detected. For example, since there is a possibility that the user has bumped into something and is unable to move, the control unit 200 sends a notification to the emergency notification destination.

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

[0135] Furthermore, the control unit 200 may change the notification destination in two stages of detection. For example, when the control unit 200 detects a large impact, the notification may be made from the notification unit 150 of the walker 1. Furthermore, when the load of the user is not detected or there is no change in the load of the user after the large impact is detected, the control unit 200 may notify another device (for example, a terminal device of a staff member, a terminal device of a family member, a device of a nurse's station, etc.).

[0136] The notifications in steps S202 and S204 may be executed by the walker 1. For example, when a large impact is detected based on a sensor value acquired by the sensor unit 160 of the walker 1, a notification may be issued from the notification unit 150, or a notification may be sent to another device via the communication unit 170. For example, the walker 1 can issue the notification in step S204 even when the power of the terminal device 2 is not turned on or the walker 1 cannot communicate with the terminal device 2.

[0137] Next, it is determined whether or not impacts have been detected a predetermined number of times or more within a predetermined period of time (step S206). For example, in FIG. 11, the control unit 200 determines whether an abnormal number of impacts have been detected five times within three days, as an example. That is, it detects whether the user is in contact with the rear frame 14 of the walker 1 within a short period of time. Note that detecting five or more impacts within three days is an example, and a different number of days may be used. The control unit 200 determines that impacts have been detected a number of times equal to or greater than a first threshold value within a first number of days.

[0138] When five or more impacts are detected within three days, the control unit 200 judges whether the user is losing balance when using the walker 1. For example, in FIG. 11, when the load transfer is unstable (for example, the load center moves by a predetermined amount or more, or the load amount displacement is a predetermined amount or more), the control unit 200 judges that the user is losing balance and that there is a problem with the walking style. Therefore, the control unit 200 selects the point "Walking Style" (step S208; Yes→step S210).

[0139] Next, the control unit 200 judges whether there is an abnormality in the biological information (step S212). Here, when the control unit 200 judges that there is an abnormality in the biological information (for example, the heart rate, blood pressure, blood sugar level, etc. are abnormally higher than a predetermined threshold, or the SpO2 is lower than a predetermined threshold), it judges that the cause is a disease. Therefore, the control unit 200 selects the point of "examination" (step S212; Yes → step S214).

[0140] Next, the control unit 200 judges whether the cumulative impacts are equal to or greater than a second threshold value (step S216). When the control unit 200 judges that the user has been bumped into at least a certain number of times, even if not in 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 points for "product" (step S216; Yes→step S218).

[0141] Then, the control unit 200 (recommendation unit 206) displays a recommendation 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 a recommendation such that a site is displayed according to need.

[0142] Here, possible recommendations made by the recommendation unit 206 at points include the following.

[0143] (1) Walking Style The control unit 200 recommends the correct walking style to the user. For example, the control unit 200 may instruct the user on how to tilt his / her posture, on the direction of force, or on the walking speed. The control unit 200 may also explain the user's walking style with a video or introduce a web page that describes the correct walking style.

[0144] (2) Medical examination The control unit 200 gives advice to the user to encourage the user to have a medical examination. For example, the control unit 200 may display hospital information or a hospital reservation page to the user. The control unit 200 may also recommend an appropriate medical department based on the determined information. The control unit 200 may also recommend the use of other devices or supplements.

[0145] (3) Product The control unit 200 advises the user on an appropriate walking unit 1. For example, the control unit 200 may recommend a walking unit of a different size (e.g., a larger size walking unit) than the walking unit 1 currently being used, or a different type of walking unit.

[0146] (4) Habits The control unit 200 may provide advice to the user regarding habits. For example, the control unit 200 may recommend appropriate times for the user to fall asleep and wake up. The control unit 200 may also provide recommendations regarding the user's living environment. For example, the control unit 200 may provide advice on using an air conditioner or on opening and closing curtains. Although the habits are described in steps S244 and S246 of FIG. 13, they may be executed before S220 of FIG. 11. That is, the control unit 200 may provide recommendations based on the user's habits.

[0147] Next, an operation example will be described using a display screen displayed on the terminal device 2. Fig. 12(a) is an example of a display screen W100 that displays recommendations when "Walking Method" and "Product" are selected as points. The control unit 200 displays a message in an area R100 on the display screen W100 as a recommendation display. In addition, the control unit 200 displays, for example, a button B100 that shows a video of how to walk and a button B102 that moves to a site that introduces recommended walking devices as a recommendation for "Walking Method".

[0148] The user can check the message displayed in area R100 and take appropriate action based on the recommendation.

[0149] 12(b) is an example of a display screen W110 that displays recommendations when "Walking Method" and "Examination" are selected as points. The control unit 200 displays a message in an area R110 on the display screen W110 as a recommendation display. The control unit 200 also displays a button B110 that displays recommendations corresponding to "Walking Method", and a button B112 that moves to a site where a doctor's appointment can be made and medical information is provided.

[0150] In this way, according to this process, it is possible to provide an appropriate recommendation when the user bumps into the walker 1 as a trigger.

[0151] [2.4.3 Third Processing Example] Next, a third processing example will be described. The third processing example in Fig. 13 replaces the second processing example in Fig. 11, and the same processes are denoted by the same reference numerals.

[0152] Here, the second processing example is triggered by the user bumping into the walker 1, but the third processing example is an embodiment in which the trigger is information acquired by the walker 1. That is, in the third processing example, the control unit 200 makes a recommendation based on event information.

[0153] The control unit 200 selects the "Walking Style" point when the shift of the user's load is not determined as a trigger (step S208; Yes -> step S210). For example, the control unit 200 selects the "Walking Style" when there is an event such as "Load Value Imbalance" or "Center of Gravity Imbalance" from the event information included in the predetermined period.

[0154] Here, the control unit 200 may select "walking style" when there is an event related to load or center of gravity a predetermined number of times or more in a period that is previously determined as a predetermined period. Also, the control unit 200 may select "walking style" when there is at least one event related to load or center of gravity on the previous day, for example.

[0155] Similarly, when there is an abnormality in the user's biometric information, the control unit 200 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 shift in the user's weight (shift in the center of gravity) and the like. Then, when the control unit 200 determines that there is another suitable product based on the information on the user's condition, biometric information, and the like, it selects the "Product" point (step S242; Yes → step S218).

[0156] Furthermore, the control unit 200 refers to the user's condition, and when it is determined that the user has a problem with the lifestyle habits, etc., the control unit 200 selects the "Habits" point (step S244; Yes→step S246). Then, the control unit 200 performs a recommendation display based on the selected points (step S220).

[0157] Here, the condition for the control unit 200 to determine that there is a problem with the lifestyle or the like may be, for example, the following first condition: Then, the control unit 200 may display a recommendation in step S220 based on the first condition.

[0158] (1) The control unit 200 determines the first condition based on the user's sleep time. For example, when the user's sleep time is short (for example, the user's sleep time on the previous day is less than 5 hours), the control unit 200 may display a recommendation such as "Go to sleep a little earlier." (2) The control unit 200 determines the first condition based on the life rhythm such as the time of falling asleep and the time of waking up. For example, when the user falls asleep late and wakes up late, the control unit 200 may display a recommendation such as "Go to bed a little earlier." In addition, when there is variation in the time of falling asleep and the time of waking up of the user, the control unit 200 may display a recommendation such as "Go to sleep at a fixed time" and "Wake up at a fixed time." (3) The first condition is determined based on the number of times the user gets out of bed during sleep (the number of times the user wakes up during sleep). For example, when the user gets out of bed (the number of times the user wakes up during sleep) three or more times per night, the control unit 200 may display a recommendation such as "Avoid drinking water before going to bed." In addition, the control unit 200 may display a recommendation such as "Make sure the temperature is appropriate" or "Use a futon 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 state of the walker 1. For example, when the user uses the walker 1 for a short time (for example, for less than 10 minutes a day), the control unit 200 may display a recommendation such as "move a little more."

[0159] In this way, the control unit 200 can determine whether there is a problem with the user's lifestyle habits and life rhythm based on the first condition and display a recommendation.

[0160] The control unit 200 may combine a plurality of conditions to display a recommendation. For example, the control unit 200 may combine a first condition and a second condition to display a recommendation.

[0161] Furthermore, the control unit 200 may combine a plurality of conditions to provide a recommendation to the user. For example, the control unit 200 may display a recommendation based on the sleep time as a first condition and the usage status of the walker 1 as a second condition.

[0162] For example, when the first condition is that the user's sleep time is shorter than a predetermined time, and the second condition is that the distance traveled by the walker 1 is long or the time spent using the walker 1 is long, the control unit 200 may display a recommendation to call attention to "take frequent breaks." This is because the control unit 200 determines that the risk of the user falling increases under these conditions.

[0163] The control unit 200 may also display a recommendation to call attention in a similar manner when the first condition is the medication status of the user, and when the second condition is when the distance traveled by the walker 1 is long or the time spent using the walker 1 is long. For example, when the user is taking medicine that makes the user feel drowsy or dizzy, the control unit 200 determines that the use of the walker 1 increases the risk of falling.

[0164] In this way, the third processing example is capable of making a recommendation based on the event information, regardless of whether or not the user has collided with the walker 1 first.

[0165] 14(a) is an example of a display screen W200 on which the control unit 200 (recommendation unit 206) has displayed a recommendation on the display unit 250 of the terminal device 2. The control unit 200 displays a message in an 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 for moving to a page for making an appointment for a medical examination or providing medical information to prompt a medical examination.

[0166] 14(b) is a diagram showing an example of a display screen W210 on which the control unit 200 has made a recommendation based on the biometric information on the display unit 250 of the terminal device 2. The control unit 200 displays a message in an area R210 of the display screen W210. The control unit 200 also displays a graph showing the transition of the biometric information (e.g., heart rate) in an 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, a past average, or may be displayed with other biometric information superimposed.

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

[0168] A pop-up display is displayed in region R220 at the foreground of display screen W220. In this way, even when terminal device 2 is being used or on standby, control unit 200 can notify the user, staff, etc. that a strong impact has been detected through the pop-up display. In addition, the pop-up display may display, for example, a call button B222. The call button B222 may register the telephone number of the user of walker 1. This allows staff, etc. to immediately check the condition of the user by selecting the call button B222.

[0169] [2.5 Effects] In this way, according to this embodiment, it is possible to recommend an appropriate walking unit to the user by using the walking unit 1. Furthermore, according to this embodiment, it is possible to appropriately grasp the condition of the user from the information acquired via the walking unit 1.

[0170] For example, sensor units (e.g., piezoelectric sensors) can be placed on both sides of the gripping portion 20, which is the grip of the walker 1, and the terminal device 2 can analyze the acquired data using software to obtain biometric information such as heart rate, blood pressure, and blood sugar level.

[0171] This allows, for example, when walking using the walker 1, to provide the user with feedback on changes in heart rate and blood pressure, making it possible to determine whether the user is walking in a way that places a strain on the user or in an appropriate, stress-free manner.

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

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

[0174] The server device 3 acquires various information from the communicable terminal device 2 and the walking unit 1. The server device 3 is, for example, a server device as described below.

[0175] Server equipment that manages medical information connected to medical institutions such as clinics, hospitals, and pharmacies Server equipment for managing citizen information in local governments, etc.

[0176] The server device 3 acquires information about the user via the walker 1 or the terminal device 2. The user information is information that can be stored in Fig. 8, and for example, the server device 3 receives and manages the user's sensor values, biometric information, and other information indicating the user's condition (for example, information about sleep, information about life rhythm, etc.).

[0177] Furthermore, the server device 3 may acquire information from devices other than the walker 1. For example, the server device receives biological information and the user's condition from each device, such as a thermometer, a weight scale, a blood pressure monitor, and a sleep monitor, either individually or via the terminal device 2.

[0178] The server device 3 can provide the biometric information and information acquired by other devices (sensors) to the doctor via the network NW. The doctor can check information about the user from the server device 3, and can utilize the information for home medical care.

[0179] In addition, by having the server device 3 provide information to local governments and other organizations, the local governments can grasp the usage status of welfare equipment, such as how often it is used and whether it is being used in a way that places a strain on the user, thereby contributing to the appropriate use of welfare equipment.

[0180] [4. Fourth embodiment] A fourth embodiment will be described. In the fourth embodiment, the walker 1 and the terminal device 2 cooperate with optional external devices and external services to provide various notifications to the user and usage methods. In this embodiment, for example, an optional external device is connected to the walker 1 described in the second embodiment, and the walker cooperates with a communicable external service. Only the points that differ from the configurations of the first and second embodiments will be described below.

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

[0182] The control unit 200 acquires illuminance, for example, from an illuminance sensor (which may be provided in the walker 1 or in the terminal device 2, for example. Also, it may be connected to an illuminance sensor in the location where the user is present and used). Then, when the control unit 200 determines that the illuminance is equal to or lower than a predetermined threshold and the surrounding environment is dark, the control unit 200 may display a notification on the display unit 250 saying "Turn on the light." Furthermore, the control unit 100 or the control unit 200 may perform a process to turn on an LED light provided in the walker 1.

[0183] In particular, when the user gets up from the bed and uses the walker 1, the LED lights turn on according to the brightness of the room. This allows the user to safely go and turn on the lights in the entire room using the walker 1.

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

[0185] Furthermore, the walker 1 may be provided with a camera device as an external device. The camera device may, for example, capture images of the walking and movement of a user using the walker 1. The control unit 200 may analyze whether the user's walking style is appropriate or not based on the images captured by the camera device, and output advice from the notification unit 150. For example, when the user's body is leaning to the left or right, the control unit 200 may notify the user that "your body is leaning. Straighten your body."

[0186] In addition, the walker 1 may be further connected to smart home appliances. For example, when the user uses the walker 1, if the illuminance detected by the illuminance sensor provided in the walker 1 described above falls below a predetermined threshold and the control unit 200 determines that the surrounding environment is dark, a process may be performed to turn on the LED light provided in the walker 1. Furthermore, the control unit 200 may further turn on a light that illuminates the entire room after turning on the LED light of the walker 1. By linking the walker 1 with smart home appliances (e.g., lighting devices, air conditioners, toilets, etc.), it is possible to assist the user in the next action to be taken. For example, when the user uses the walker 1 to move to the tray, the walker 1 or the terminal device 2 may transmit a control signal to automatically open the lid of the toilet seat of the toilet. The user can move directly from the walker 1 to the toilet seat of the tray without having to take the trouble of opening the lid of the toilet seat, 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 the terminal device 2 communicates with an external service to acquire information. For example, the control unit 100 may acquire the time from a time server via the communication unit 170. At this time, if it is late at night, the control unit 100 may issue an announcement saying, "Isn't it about time to go to bed?" In addition, when 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] The walker 1 may also obtain information about the weather from a server that provides a weather forecast. For example, the control unit 100 may obtain a weather forecast as information about the current weather from the server based on the position and time information of the walker 1. Then, the control unit 100 may issue a warning such as "Check to see if the anti-slip rubber has worn down" if rain or the like is forecast.

[0189] These processes may be implemented by the walker 1 or by the terminal device 2. When implemented by the terminal device 2, the control unit 200 executes each process and transmits a control signal to the walker 1 as necessary.

[0190] In this way, according to the present embodiment, when an external device is connected to the walker 1, the convenience of the walker 1 can be further improved. In addition, the walker 1 or the terminal device 2 can provide appropriate recommendations to the user by acquiring information from an external service provided by a server.
