Description

Electronic device that communicates with a wheelchair treadmill

[0001] Embodiments of the present disclosure relate to an electronic device communicating with a treadmill for a wheelchair, and more particularly, to an electronic device communicating with a treadmill for a wheelchair to provide information regarding a user's exercise.

[0002] Wheelchairs are used as devices to assist people with physical disabilities. Long-term wheelchair use can lead to a decline in physical fitness due to lack of exercise. To address this issue, interest in wheelchair treadmills, which allow wheelchair users to exercise while on a treadmill, is growing.

[0003] However, unlike conventional treadmills, these wheelchair treadmills can present a problem: since the user exercises while seated in a wheelchair, they cannot measure the user's exercise volume. The inability to measure the user's exercise volume results in a lack of content that motivates the user to continue exercising, which can result in poor exercise outcomes for users using wheelchair treadmills.

[0004] Embodiments of the present disclosure address various issues, including the aforementioned ones, by providing an electronic device that communicates with a wheelchair treadmill that provides information about the user's exercise. However, these tasks are exemplary and are not intended to limit the scope of the present disclosure.

[0005] According to one aspect of the present disclosure, in an electronic device, the electronic device includes a communication module for transmitting and receiving data communicating with a treadmill for a wheelchair, a display for outputting an application screen, and a processor, wherein the processor obtains first data representing rotation of a first roller structure and second data representing rotation of a second roller structure from the treadmill for a wheelchair through the communication module in an input mode, analyzes the first data and the second data, and converts them into data related to rotation of a first main wheel of a wheelchair placed on top of the treadmill for a wheelchair and data related to rotation of a second main wheel, and matches an input command based on the data related to rotation of the first main wheel and the data related to rotation of the second main wheel, and controls the application according to the input command.

[0009] According to the present embodiment, the processor can collect the user's exercise analysis data in the training mode, evaluate the user's exercise ability based on the user's exercise analysis data, and generate a personalized training mode using an artificial intelligence model based on the evaluated user's exercise ability data.

[0010] According to the present embodiment, when the numerical value of the user's specified exercise ability data is lower than the average data, the processor can generate the personalized training mode as training to strengthen the exercise ability lower than the average data from the user's exercise ability data.

[0011] According to the present embodiment, the processor may generate the personalized training mode as training to enhance the overall exercise ability of the user based on the history of the exercise ability data of the user when the numerical value of the exercise ability data of the user is equal to or higher than the average data.

[0036] The present disclosure is capable of various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present disclosure, as well as methods for achieving them, will become clearer with reference to the embodiments described in detail below, along with the drawings. However, the present disclosure is not limited to the embodiments disclosed below and may be implemented in various forms.

[0037] In the examples below, the terms first, second, etc. are not used in a limiting sense, but are used for the purpose of distinguishing one component from another.

[0038] In the examples below, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0039] In the following examples, terms such as “include” or “have” mean that a feature or component described in the specification is present, and do not preclude the possibility that one or more other features or components may be added.

[0040] In the following examples, when a part such as a layer, region, component, etc. is said to be on or above another part, it includes not only the case where it is directly above the other part, but also the case where another region, component, etc. is interposed in between.

[0041] For convenience of explanation, the sizes of components in the drawings may be exaggerated or reduced. For example, the sizes and thicknesses of each component shown in the drawings are arbitrarily indicated for convenience of explanation, and thus the present disclosure is not necessarily limited to the figures shown.

[0042] In some embodiments, where implementations are otherwise feasible, specific sequences of operations may be performed in a different order than described. For example, two steps described in succession may be performed substantially simultaneously, or in a reverse order from the described order.

[0043] In this specification, “A and / or B” refers to the case where it is A, or B, or both A and B. And, “at least one of A and B” refers to the case where it is A, or B, or both A and B.

[0044] In the following examples, when it is said that layers, regions, components, etc. are connected, it includes cases where the layers, regions, components, etc. are directly connected, and / or cases where other layers, regions, components, etc. are interposed between the layers, regions, and components and are indirectly connected. For example, when it is said in this specification that layers, regions, components, etc. are electrically connected, it refers to cases where the layers, regions, components, etc. are directly electrically connected, and / or cases where other layers, regions, components, etc. are interposed between them and are indirectly electrically connected.

[0045] The x-axis, y-axis, and z-axis are not limited to the three axes in the Cartesian coordinate system, but can be interpreted in a broader sense that includes them. For example, the x-axis, y-axis, and z-axis may be orthogonal to each other, but they can also refer to different directions that are not orthogonal to each other.

[0046] The advantages and features of the present disclosure, and methods for achieving them, will become clearer with reference to the embodiments described below in detail with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided solely to ensure that the disclosure is complete and to fully inform those skilled in the art of the scope of the present disclosure, and the present disclosure is defined solely by the scope of the claims.

[0047] The terminology used in this disclosure is for the purpose of describing embodiments only and is not intended to limit the present disclosure. In this disclosure, the singular may also include the plural unless specifically stated otherwise. The terms "comprises" and / or "comprising" as used herein do not exclude the presence or addition of one or more other components in addition to the mentioned components. Like reference numerals refer to like components throughout the disclosure, and "and / or" may include each and any combination of one or more of the mentioned components. Although "first", "second", etc. are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from another. Therefore, it should be understood that a first component mentioned below may also be a second component within the technical spirit of the present disclosure.

[0048] The word "exemplary" is used herein to mean "serving as an example or illustration." Any embodiment described herein as "exemplary" should not necessarily be construed as preferred or advantageous over other embodiments.

[0049] Embodiments of the present disclosure may be described in terms of a function or a block that performs a function. A block, which may be referred to as a "unit" or a "module" in the present disclosure, may be physically implemented by analog or digital circuits such as logic gates, integrated circuits, microprocessors, microcontrollers, memories, passive electronic components, active electronic components, optical components, hardwired circuits, etc., and may optionally be driven by firmware and software. Furthermore, the term "unit" as used in the disclosure refers to software, hardware elements such as FPGAs or ASICs, and the "unit" may perform certain roles. However, the "unit" is not limited to software or hardware. The "unit" may be configured to reside on an addressable storage medium and may be configured to execute one or more processors. Thus, as an example, a "part" may include elements such as software elements, object-oriented software elements, class elements, and task elements, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables. The functionality provided within the elements and "parts" may be combined into a smaller number of elements and "parts" or further separated into additional elements and "parts."

[0050] Embodiments of the present disclosure can be implemented using at least one software program running on at least one hardware device and capable of performing network management functions to control elements.

[0051] Spatially relative terms such as "below," "beneath," "lower," "above," and "upper" may be used to readily describe the relationship between one component and other components as depicted in the drawings. Spatially relative terms may be understood to encompass different orientations of components during use or operation in addition to the orientations depicted in the drawings. For example, if a component depicted in the drawings were flipped over, a component described as "below" or "beneath" another component may end up "above" the other component. Thus, the exemplary term "below" may encompass both the above and below orientations. Components may also be oriented in other directions, and thus spatially relative terms may be interpreted accordingly.

[0052] Unless otherwise defined, all terms (including technical and scientific terms) used in this disclosure may be used with the meaning commonly understood by those skilled in the art to which this disclosure pertains. Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0053] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals and redundant descriptions thereof will be omitted.

[0054] FIG. 1 is a perspective view schematically illustrating a treadmill for a wheelchair according to an exemplary embodiment of the present disclosure, FIG. 2 is a perspective view schematically illustrating an example of a state in which a wheelchair is positioned on a treadmill for a wheelchair according to an exemplary embodiment of the present disclosure, and FIG. 3 is a cross-sectional view schematically illustrating a structure of a first roller structure according to an exemplary embodiment of the present disclosure.

[0055] Referring to FIGS. 1, 2, and 3, a treadmill (100) for a wheelchair may include a first frame (110), a first roller structure (120), a second roller structure (130), a communication module (140), and a second frame (150).

[0056] The first frame (110) can support at least a portion of the load applied to the wheelchair treadmill (100). The first frame (110) can support the main wheels (210) of the wheelchair (200) positioned on the wheelchair treadmill (100). The first frame (110) can be placed on the ground. For example, the first frame (110) can be formed of a relatively heavy material (e.g., metal) so that the position of the wheelchair treadmill (100) does not change fluidly while the user is exercising.

[0057] The first roller structure (120) may be rotatably coupled to the first frame (110). For example, the first roller structure (120) may be disposed inside the first frame (110) so as to be surrounded by the first frame (110). The first roller structure (120) may be rotatable by the rotation of one of the main wheels (210) of the wheelchair (200). For example, the first roller structure (120) may have a circular cross-section so as to be smoothly rotatable with respect to the first frame (110). The first roller structure (120) may extend in a first direction (e.g., +x direction) and thus may have a cylinder shape having a length in the first direction (e.g., +x direction). According to one embodiment, the first roller structure (120) may include a plurality of rollers. The plurality of rollers may be spaced apart from each other along a second direction (e.g., +y direction) that is transverse to the first direction (e.g., +x direction). While the wheelchair (200) is positioned on the wheelchair treadmill (100), one of the main wheels (210) of the wheelchair (200) may be positioned (or accommodated) within a space between the plurality of rollers.

[0058] The second roller structure (130) may be rotatably coupled to the first frame (110). For example, the second roller structure (130) may be disposed inside the first frame (110) so as to be surrounded by the first frame (110). The second roller structure (130) may be rotatable by the rotation of another one of the main wheels (210) of the wheelchair (200). For example, the second roller structure (130) may have a circular cross-section so as to be smoothly rotatable with respect to the first frame (110). The second roller structure (130) may have a cylinder shape having a length in the first direction (e.g., the +x direction) by extending in the first direction (e.g., the +x direction). According to one embodiment, the second roller structure (130) may include a plurality of rollers. The plurality of rollers may be spaced apart from each other along a second direction (e.g., +y direction) that is transverse to the first direction (e.g., +x direction). While the wheelchair (200) is positioned on the wheelchair treadmill (100), another one of the main wheels (210) of the wheelchair (200) may be positioned (or accommodated) within a space between the plurality of rollers. The second roller structure (130) may be spaced apart from the first roller structure (120) along the first direction (e.g., +x direction).

[0059] The communication module (140) can establish a communication connection between the wheelchair treadmill (100) and an external electronic device (e.g., the electronic device (300) of FIG. 8). For example, the communication module (140) can transmit data acquired by the wheelchair treadmill (100) to the electronic device (300) or receive data from the electronic device (300). According to one embodiment, the communication module (140) can perform wireless communication with the electronic device (300). For example, the communication module (140) can perform wireless communication with the electronic device (300) through various communication techniques, such as a cellular communication technique, a Wi-Fi communication technique, an NFC technique, or a Bluetooth communication technique. The communication module (140) can be disposed between the first roller structure (120) and the second roller structure (130).

[0060] The second frame (150) can support the auxiliary wheels (220) of the wheelchair (200). The second frame (150) can be in contact with the auxiliary wheels (220) of the wheelchair (200). The second frame (150) can be coupled to the first frame (110). For example, the second frame (150) can extend from the first frame (110) in a second direction (e.g., +y direction). For example, the second frame (150) can include, but is not limited to, a plurality of plates that are disconnected from each other at a specified interval. In one embodiment, the second frame (150) can include a plurality of guides (151). The second frame (150) can be referred to (or otherwise named) as a footrest.

[0061] A plurality of guides (151) can prevent (or limit) the rotation of the wheelchair (200) while the user is exercising on the wheelchair treadmill (100). The plurality of guides (151) can be arranged between the auxiliary wheels (220) of the wheelchair (200) while the wheelchair (200) is positioned on the wheelchair treadmill (100). As the plurality of guides (151) limit the rotation of the wheelchair (200), the user of the wheelchair treadmill (100) can exercise safely. The plurality of guides (151) can be spaced apart from each other. For example, the plurality of guides (151) can be spaced apart from each other along a first direction (e.g., +x direction). For example, the distance between the plurality of guides (151) can be smaller than the distance between the auxiliary wheels (220). A plurality of guides (151) may be arranged (or formed) on the second frame (150). For example, the plurality of guides (151) may protrude from one side of the second frame (150) that contacts the auxiliary wheels (220). For example, the plurality of guides (151) may protrude from one side of the second frame (150) along a third direction (e.g., +z direction) that is perpendicular to both the first direction (e.g., +x direction) and the second direction (e.g., +y direction).

[0062] According to one embodiment, the first roller structure (120) may include a roller (121), a shaft (122), and a holder (123). The following description will be based on the first roller structure (120), but the embodiments are not limited thereto. For example, the description of the first roller structure (120) may be substantially equally applied to the second roller structure (130). The roller (121) may be rotatable with respect to the first frame (110). The roller (121) may be configured to rotate by the rotation of the main wheels (210). The shaft (122) may pass through the roller (121) and the first frame (110). The shaft (122) may be rotatable together with the roller (121), and thus may be rotatable relative to the first frame (110). The holder (123) can be coupled to the shaft (122) to impart a rotational moment of inertia to the roller (121). The holder (123) can be rotated together with the shaft (122) and the roller (121) by being penetrated by the shaft (122). The holder (123) can relatively increase the moment of inertia of the first roller structure (120) compared to a case where the holder (123) is not present. As the moment of inertia of the first roller structure (120) is relatively increased, the rotation of the first roller structure (120) can be relatively prolonged. As the rotation of the first roller structure (120) is prolonged, movement of a user with physical disabilities can be facilitated. The cross-sectional area of ​​the holder (123) can be larger than the cross-sectional areas of the shaft (122) and the roller (121) when looking at the first roller structure (120) along the extension direction of the shaft (122). For example, the shape of the cross-sectional area of ​​the holder (123) may be circular, but is not limited thereto. The shape of the cross-sectional area of ​​the holder (123) may also be elliptical and / or polygonal.

[0063] FIG. 4 is a top view schematically illustrating a portion of a treadmill for a wheelchair according to an exemplary embodiment of the present disclosure.

[0064] Referring to FIG. 4, a treadmill (100) for a wheelchair may include a first action part (160), a first sensor part (170), a second action part (180), and a second sensor part (190).

[0065] The first action part (160) can be coupled to the first roller structure (120) so as to be rotatable together with the first roller structure (120). For example, the first action part (160) can be disposed (or inserted) inside the first roller structure (120), but is not limited thereto. For example, the first action part (160) can also be exposed to the outside of the first roller structure (120). For example, the first action part (160) can be coupled to one end of the first roller structure (120) that is closer to the second roller structure (130) (or the communication module (140)) among the two ends of the first roller structure (120).

[0066] The first sensor unit (170) may be arranged on the first frame (110). The first sensor unit (170) may be configured to obtain first data indicating the rotation of the first roller structure (120) by interacting with the first action unit (160). The first sensor unit (170) may be directed toward the first action unit (160). For example, when the first action unit (160) is a magnetic body (or magnet), the first sensor unit (170) may be configured to obtain the first data by interacting with the first action unit (160) based on a magnetic field, but is not limited thereto.

[0067] The second action part (180) can be coupled to the second roller structure (130) so as to be rotatable together with the second roller structure (130). For example, the second action part (180) can be disposed (or inserted) inside the second roller structure (130), but is not limited thereto. For example, the second action part (180) can also be exposed to the outside of the second roller structure (130). For example, the second action part (180) can be coupled to one end of the second roller structure (130) that is closer to the first roller structure (120) (or the communication module (140)) among the two ends of the second roller structure (130).

[0068] The second sensor unit (190) may be arranged on the first frame (110). The second sensor unit (190) may be configured to obtain second data indicating the rotation of the second roller structure (130) by interacting with the second action unit (180). The second sensor unit (190) may be directed toward the second action unit (180). For example, when the second action unit (180) is a magnetic body (or magnet), the second sensor unit (190) may be configured to obtain the second data by interacting with the second action unit (180) based on a magnetic field, but is not limited thereto.

[0069] According to one embodiment, the communication module (140) may be configured to transmit at least one of the first data obtained from the first sensor unit (170) and the second data obtained from the second sensor unit (190) to an external electronic device (e.g., the electronic device (300) of FIG. 8) for displaying the user's exercise using the wheelchair treadmill (100). The first data and the second data may include the rotation speed and rotation direction of the first roller structure (120), and the rotation speed and rotation direction of the second roller structure (130), respectively. Hereinafter, a method of obtaining the first data based on the first action unit (160) and the first sensor unit (170) will be described, but this is for convenience of explanation. The description of the method for obtaining first data based on the first action unit (160) and the first sensor unit (170) can be substantially equally applied to the method for obtaining second data based on the second action unit (180) and the second sensor unit (190).

[0070] FIG. 5 is a drawing schematically illustrating the relationship between a first action part and a first sensor part of a treadmill for a wheelchair according to an exemplary embodiment of the present disclosure.

[0071] Referring to FIG. 5, the first action part (160) may include a plurality of magnets (161, 162). The magnetism of the plurality of magnets (161, 162) may be different from each other. For example, the magnetism of the first magnet (161) may be stronger than the magnetism of the second magnet (162). The plurality of magnets (161, 162) may be arranged asymmetrically with respect to the center of the first roller structure (120). For example, the plurality of magnets (161, 162) may all be arranged within one quadrant of the first roller structure (120) with respect to the center of the first roller structure (120), but are not limited thereto.

[0072] The first sensor unit (170) may include at least one magnetic field sensor (171, 172). The at least one magnetic field sensor (171, 172) may be referred to as a Hall sensor. For example, the at least one magnetic field sensor (171, 172) may include a first magnetic field sensor (171) and a second magnetic field sensor (172). The first magnetic field sensor (171) and the second magnetic field sensor (172) may be spaced apart from each other with respect to a second direction (e.g., +y direction).

[0073] At least one magnetic field sensor (171, 172) can obtain first data for identifying the rotational direction of the first roller structure (120) based on the time interval between sections in which a magnetic field is detected by a plurality of magnets (161, 162).

[0074] At least one magnetic field sensor (171, 172) can obtain first data for identifying the rotation direction of the first roller structure (120) based on the order in which the plurality of magnets (161, 162) are detected. For example, when the first magnet (161) and the second magnet (162) are arranged in a clockwise direction, and when the first roller structure (120) rotates in a clockwise direction, the first magnetic field sensor (171) can obtain first data having a section in which the magnitude of the magnetic field increases. For example, when the first magnet (161) and the second magnet (162) are arranged in a clockwise direction, and when the first roller structure (120) rotates in a counterclockwise direction, the first magnetic field sensor (171) can obtain first data having a section in which the magnitude of the magnetic field decreases.

[0076] Referring to FIG. 6, the first action part (160) may include a plurality of magnets (161, 162). The magnetism of the plurality of magnets (161, 162) may be different from each other. For example, the magnetism of the first magnet (161) may be stronger than the magnetism of the second magnet (162). The plurality of magnets (161, 162) may be arranged symmetrically with respect to the center of the first roller structure (120).

[0079] At least one magnetic field sensor (171, 172) can obtain first data for identifying the rotational direction of the first roller structure (120) based on the order in which the plurality of magnets (161, 162) are detected. For example, when the first roller structure (120) rotates clockwise, the first magnet (161) can be detected by the first magnetic field sensor (171) before the second magnet (162). The rotational direction of the first roller structure (120) can be identified depending on the type of the plurality of magnets (161, 162) that are preferentially identified by the at least one magnetic field sensor (171, 172).

The plurality of magnets (161, 162, 163, 164) may be arranged symmetrically with respect to the center of the first roller structure (120). For example, the first magnet (161) and the third magnet (163) may face each other with respect to the center of the first roller structure (120), and the second magnet (162) and the fourth magnet (164) may face each other with respect to the center of the first roller structure (120).

For example, the at least one magnetic field sensor (171, 172) may include a first magnetic field sensor (171) and a second magnetic field sensor (172). The first magnetic field sensor (171) and the second magnetic field sensor (172) may be spaced apart from each other with respect to a second direction (e.g., +y direction).

[0083] At least one magnetic field sensor (171, 172) can obtain first data for identifying the rotational direction of the first roller structure (120) based on the time interval between sections in which a magnetic field is detected by a plurality of magnets (161, 162, 163, 164).

For example, when the first roller structure (120) rotates clockwise, the first magnetic field sensor (171) can obtain first data having a section in which the magnitude of the magnetic field increases. For example, when the first roller structure (120) rotates counterclockwise, the first magnetic field sensor (171) can obtain first data having a section in which the magnitude of the magnetic field decreases.

[0085] As described above, the treadmill (100) for a wheelchair according to one embodiment can easily obtain data regarding the rotation speed and rotation direction of the first roller structure (120) through the arrangement of the first action part (160) and the first sensor part (170). Hereinafter, a method for providing content to a user through first data indicating the rotation of the first roller structure (120) and second data indicating the rotation of the second roller structure (130) will be described.

[0087] Referring to FIG. 8, according to one embodiment, a system including a treadmill for a wheelchair may include a treadmill for a wheelchair (100), an electronic device (300), and a server (400). However, the present invention is not limited thereto. For example, in a system including a treadmill for a wheelchair, one of the electronic device (300) and the server (400) may be omitted.

[0088] According to one embodiment, the electronic device (300) may include a processor, a display, and / or a communication module.

[0089] The operations described as operations of the electronic device (300) can be performed by the processor of the electronic device (300).

[0090] The communication module of the electronic device (300) is communicatively connected to the wheelchair treadmill (100) via Bluetooth communication, and can transmit and receive information.

[0091] According to one embodiment, a treadmill (100) for a wheelchair can transmit at least one of first data and second data to an electronic device (300). The first data and the second data can be expressed based on binary code. For example, at least one of the first data and the second data can be expressed as shown in Table 1 below.

[0092]

[0093] [Table 1]

[0094]

[0095]

[0096] In Table 1 above, the Header can be used as a criterion for determining the start of data when transmitting binary code. Battery Volt can represent battery voltage (mV), and Measure Time can represent measurement time. The measurement time can be 250 ms. Wheel Pos can represent the position of the wheel. Wheel Pos can represent the position of the wheel through the number of times the action parts (160, 180) are detected by each of the sensor parts (170, 180). The first data and the second data, which are exemplarily expressed as in Table 1 above, can be transmitted to the electronic device (300) at a cycle of 250 ms, that is, four times per second. The electronic device (300) can obtain information about the movement of the user of the wheelchair treadmill (100) based on receiving the first data and the second data. The electronic device (300) can perform operations on first data and second data through an application processor within the electronic device (300). For example, the electronic device (300) can obtain information about the user's movement through the following mathematical equations.

[0097] [Mathematical Formula 1]

[0098] Movement distance = 2πr(current Wheel Pos - previous Wheel Pos) / (number of magnets in the roller structure)

[0099] In mathematical expression 1, r may represent the radius of one of the first roller structure (120) or the second roller structure (130).

[0100]

[0101] [Equation 2]

[0102] Exercise time = (Current Measure Time - Previous Measure Time) * (Data transmission cycle)

[0103]

[0104] For example, if the data transmission cycle in Equation 2 is 250 ms, a value of 0.25 can be entered into Equation 2.

[0105]

[0106] [Equation 3]

[0107] Speed ​​(km / h) = (distance / time)*3.6

[0108]

[0109] Meanwhile, the operation using the first data and the second data may be performed by a server (400) that receives the first data and the second data through an electronic device (300).

[0114] According to various embodiments, the electronic device (300) may obtain first data and second data from a treadmill for a wheelchair (200) through a communication module in operation 920.

[0115] According to one embodiment, the first data may be data indicating the rotation of the first roller structure (120) as a result of the first sensor portion of the treadmill interacting with the first action portion. For example, if the first action portion is a magnetic body (or magnet), the first data may be data generated as the first action portion and the first sensor portion interact based on a magnetic field.

[0116] In one embodiment, the second data may be data indicating the rotation of the second roller structure (130) as a result of the second sensor portion of the treadmill interacting with the second action portion.

For example, in response to the rotation angle of the second main wheel (210-2) being c degrees and the value obtained by dividing the c angle by the first angle being greater than 2 and less than or equal to 3, the cursor (1) can be moved three times in the third direction. For example, in response to the rotation angle of the second main wheel (210-2) being d degrees and the value obtained by dividing the d angle by the first angle being greater than 3 and less than or equal to 4, the cursor (1) can be moved four times in the third direction.

[0168] According to one embodiment, the electronic device (300) can move the cursor (1) by matching the eighth input command in response to the second main wheel (210-2) rotating backward. For example, the electronic device (300) can move the cursor (1) once in the fourth direction (e.g., -y direction) in response to the rotation angle of the second main wheel (210-2) being -a degrees and the value obtained by dividing the -a angle by the second angle (e.g., -45 degrees) being greater than 0 and less than or equal to 1.

[0178] FIG. 10A is a flowchart schematically illustrating an example of the operation of an electronic device according to an exemplary embodiment of the present disclosure.

[0179] According to various embodiments, the electronic device (300) may execute a training mode in operation 1010.

[0195] According to various embodiments, the electronic device (300) may, in operation 1110, collect exercise analysis data of the user in training mode.

[0196] For example, in operation 1040 of 10a, the electronic device (300) may collect at least one of the user's movement analysis data from among the time taken for the user to complete a specified movement, the average rotational speed while performing the specified movement, the change in rotational speed while performing the specified movement, the change in rotational force while performing the specified movement, the rotational inertia when starting or stopping the movement, and the movement consistency with the training movement.

[0197] According to various embodiments, the electronic device (300) may, in operation 1120, evaluate the user's motor ability based on the user's motor analysis data.

[0198] For example, the electronic device (300) can evaluate the user's manipulation ability, which evaluates whether the user can precisely control the rotation direction, rotation angle, rotation speed, etc. For example, the electronic device (300) can evaluate the user's upper body muscle strength required to push or pull the wheelchair (200) based on the rotational force data. For example, the electronic device (300) can evaluate the reaction speed, which is related to how quickly the user can react and manipulate the wheelchair (200) based on the rotational speed and time. For example, the electronic device (300) can evaluate the user's endurance, which is related to the ability to perform continuous exercise and operate the wheelchair (200) for a long period of time through long-distance wheelchair (200) training. For example, the electronic device (300) can evaluate the user's skill proficiency, which is related to how precisely the user can operate the wheelchair (200) based on the rotational angle data. For example, the electronic device (300) can evaluate the user's mobility, which is related to how freely the user can move in various environments.

[0199] According to various embodiments, the electronic device (300) may, in operation 1130, generate a personalized training mode using an AI model based on the user's exercise ability data.

[0200] According to one embodiment, the electronic device (300) may input the user's motor ability data evaluated in operation 1120 into the learned AI model. For example, the electronic device (300) may input at least one of the user's operating ability, the user's upper body muscle strength, reaction speed, endurance, skill proficiency, and mobility into the learned AI model.

[0201] For example, the learned AI model may be an AI model trained with the user's athletic ability data, such as the user's manipulation ability, the user's upper body strength, reaction speed, endurance, skill proficiency, and mobility, and may be a model trained to output a personalized training mode when the user's athletic ability data is input. The AI ​​model may be an artificial neural network model written in a specified language and including multiple layers and / or operations. The AI ​​model may be at least one of various types of networks, such as a convolution neural network (CNN), a region with convolution neural network (R-CNN), a region proposal network (RPN), a recurrent neural network (RNN), a stacking-based deep neural network (S-DNN), a state-space dynamic neural network (S-SDNN), a deconvolution network, a deep belief network (DBN), a restricted boltzman machine (RBM), a fully convolutional network, a long short-term memory (LSTM) network, and a classification network.

[0202] According to one embodiment, the electronic device (300) can generate a personalized training mode from a learned AI model.

[0203] The electronic device (300) can create a personalized training mode according to the user's exercise ability.

[0204] If the user's athletic ability data is lower than the average, the personalized training mode may be designed to strengthen the lower-than-average athletic ability data. For example, an electronic device may create a personalized training mode centered on repeating specified movements to strengthen a specified athletic ability.

[0205] For example, if a user's athletic ability is above or similar to average, a personalized training mode may be a training mode that increases the difficulty of exercises to enhance the user's overall athletic ability based on the user's athletic ability history when the user executes the training mode. For example, an electronic device may create a personalized training mode that alternates between multiple movements at a higher intensity than the previous training mode to enhance overall athletic ability.

[0206] According to various embodiments, the electronic device (300) may execute and provide feedback in a personalized training mode at operation 1140.

[0207] According to one embodiment, the electronic device (300) may execute the personalized training mode generated in operation 1130 and collect user exercise analysis data in the personalized training mode to evaluate the user's exercise ability.

[0208] In one embodiment, the electronic device (300) may update the AI ​​model based on the user's exercise ability data evaluated in the personalized training mode. For example, the electronic device (300) may modify the weights of the AI ​​model based on the user's exercise ability data.

[0211] According to one embodiment, the electronic device (300) can input left and right upper body muscle strength data in training mode into a learned AI model to create a personalized training mode to balance left and right.
