[0046] (Structure of the motion detection system according to the embodiments of this disclosure)

[0047] Examples of embodiments of the disclosed technology will be described below with reference to the accompanying drawings. Furthermore, identical or equivalent structural elements and parts are labeled with the same reference numerals in each drawing. Additionally, the scale of the drawings may be exaggerated for ease of explanation, differing from the actual scale.

[0048] Figure 1 This is a diagram illustrating the structure of the motion detection system 1000 according to this embodiment. (See diagram for details.) Figure 1 As shown, the motion detection system 1000 includes a motion detection component 150 and a server 300. The motion detection component 150 and the server 300 perform wireless communication.

[0049] (Motion detection component)

[0050] The following is an overview of the motion detection component. Furthermore, in this disclosure, the use of “~” for a numerical range refers to a range that includes the minimum and maximum values ​​shown before and after the “~”, respectively.

[0051] A motion detection component is a component used to detect the motion of a mounted object. As a motion detection component, it can employ sensors that detect motion based on hand extension or retraction, such as extension sensors, accelerometers, angular velocity sensors, and magnetic sensors, or time-axis detection sensors that detect motion based on hand tilt or position. In this embodiment, the case where the motion detection component is an extension sensor will be described as an example.

[0052] The motion detection component of this embodiment includes: a mounting portion mounted on a mounted body, having a telescopic portion that extends and retracts due to the movement of the mounted body; and a wiring electrode portion, having: a wiring portion disposed on at least a portion of the telescopic portion of the mounting portion, having a first wiring portion including a conductive wire and a second wiring portion including a conductive wire; and an electrode portion having a first electrode portion electrically connected to the first wiring portion and a second electrode portion electrically connected to the second wiring portion. When the telescopic portion of the mounting portion on which the wiring portion is disposed extends and retracts due to the movement of the mounted body, the contact state of the first wiring portion and the second wiring portion changes, thereby changing the resistance value between the first electrode portion and the second electrode portion.

[0053] Regarding the motion detection component of this embodiment, when the telescopic portion extends or retracts (i.e., elongates and contracts) due to the movement of the mounted body, the contact state of the first wiring portion and the second wiring portion changes, thereby changing the resistance value between the first electrode portion and the second electrode portion. By detecting this change in resistance value, the movement of the mounted body can be detected.

[0054] Furthermore, regarding the motion detection component of this embodiment, the wiring electrode portion used for detecting motion is composed of conductive wires. Therefore, its durability is also high.

[0055] Furthermore, a wiring section made of conductive wires is provided at the stretchable portion of the mounting part, which is made of stretchable fabric. Therefore, when installed on the object being mounted, it does not easily feel out of place and has an excellent installation feel.

[0056] Furthermore, for the glove-type input device and the glove with deformation sensor in Patent Document 1, calibration is required when the hand is open and closed. If the glove is used continuously, the sensor position will gradually shift, potentially reducing detection accuracy. On the other hand, the motion detection component of this embodiment does not require calibration, can be used immediately after installation, and has a wider tolerance range for positional shift.

[0057] In this disclosure, "a change in resistance between the first electrode and the second electrode" means: 1) the resistance increases or decreases while the first electrode and the second electrode are in a conductive state; or 2) the first electrode and the second electrode change from a conductive state to a non-conductive state or from a non-conductive state to a conductive state. Furthermore, this change in resistance does not include changes in resistance caused by damage to the electrode, the wiring portion, or the joint between the electrode and the wiring portion.

[0058] The phrase "at least a portion of the first wiring section and the second wiring section are in contact" also includes: in the case of having other wiring sections (such as a third wiring section) besides the first wiring section and the second wiring section, the first wiring section and the second wiring section are in contact with at least a portion of the other wiring section sandwiched between them.

[0059] "The wiring part is located in the telescopic part" means that "the wiring part is located on the surface of the telescopic component" or "the wiring part is located inside the telescopic fabric".

[0060] Furthermore, "the wiring portion is provided on the surface of the stretchable fabric" means that the wiring portion (i.e., conductive wire-like body) is provided in the fabric layers constituting the front and back sides of the stretchable fabric (including fabric layers that partially constitute the front and back sides). In other words, "the wiring portion is provided on the surface of the stretchable fabric" means that the electrode portion or the wiring portion (i.e., conductive wire-like body) is provided with at least a portion of the conductive wire-like body constituting the wiring portion exposed from the stretchable fabric.

[0061] On the other hand, "the wiring part is provided inside the stretchable fabric" means that a wiring part (i.e. a conductive wire) is provided in the inner layer of the stretchable fabric, for example, in the fabric layer that is the inner layer of the stretchable fabric or between fabric layers.

[0062] The term "the mounting part having a telescopic portion made of a stretchable fabric" includes: a position of the mounting part corresponding to the telescopic portion being made of a stretchable fabric, and a wiring portion being provided on the stretchable fabric; and a position of attaching a stretchable fabric having a wiring portion to the surface of the mounting part corresponding to the telescopic portion. Furthermore, examples of methods for providing the telescopic portion include: attaching it using adhesive, or installing it by sewing.

[0063] (Structure of the motion detection component)

[0064] An example of a motion detection component according to this embodiment will be described below with reference to the accompanying drawings. The motion detection component 150 of this embodiment is a fabric with electrode wiring. In this embodiment, the motion detection component 150 is as follows: Figure 2 The following explanation will be based on an example of a glove-shaped component as shown. Specifically, the motion detection component 150 includes, for example, a glove-shaped mounting section 10 (an example of a mounting section), a wiring electrode section 100, and a communication module 202.

[0065] (Glove-shaped mounting section)

[0066] The glove-shaped fitting 10 is a glove-shaped fitting that is fitted onto the hand of a human body that is the object being fitted.

[0067] The glove-shaped fitting 10 has: a wrist part 1, which is fitted to the wrist of a human body; a finger part 2, which is fitted to the fingers of a human body; and a main body part 3, which connects the wrist part 1 and the finger part 2.

[0068] Furthermore, the connection between the wrist part 1, the finger part 2 and the main body part 3 (the part corresponding to the metacarpophalangeal joint), and the finger part 2 (the part corresponding to the distal interphalangeal joint and the proximal interphalangeal joint) are equivalent to an example of "the retractable part that extends and retracts due to the movement of the installed body".

[0069] In addition, the part of finger 2 that faces the back of the hand opposite the interphalangeal joint is equivalent to an example of "the telescopic part of the mounting part with wiring provided".

[0070] Here, the glove-like fitting 10 has, for example, five finger portions 2 corresponding to each finger. Specifically, the glove-like fitting 10 has, for example, the following portions as finger portions 2: a thumb portion 2A fitted to the thumb, an index finger portion 2B fitted to the index finger, a middle finger portion 2C fitted to the middle finger, a ring finger portion 2D fitted to the ring finger, and a little finger portion 2E fitted to the little finger.

[0071] However, the structure of the finger portion 2 is not limited to the structure described above. Alternatively, the glove-shaped mounting portion 10 may have, for example, two parts that serve as the finger portion 2: a thumb portion mounted on the thumb; and finger portions mounted on the index, middle, ring, and little fingers.

[0072] The glove-shaped fitting part 10 is composed of, for example, three layers of fabric: a surface fabric layer 10A forming the surface, an inner fabric layer 10B forming the inside, and an intermediate fabric layer 10C located between the surface fabric layer 10A and the inner fabric layer 10B.

[0073] In addition to the triple fabric layer, the glove-shaped fitting part 10 may also be composed of a single (one-layer), double (two-layer), or quadruple (four-layer) or more fabric layers.

[0074] Furthermore, for multiple fitting parts consisting of two or more layers of fabric, for example, a method of sewing together after each layer of fabric is made can be used, or a knitting machine can be used to make multiple glove-shaped fitting parts 10 at the same time.

[0075] The glove-shaped fitting part 10 is made of, for example, a stretchable fabric. However, the glove-shaped fitting part 10 may be made of a soft fabric, and at least the part of the finger 2 facing the back of the hand near the interphalangeal joint (an example of the stretchable part of the fitting part with the wiring part) may be made of a stretchable fabric.

[0076] As a stretchable fabric, woven fabrics are a typical example. The glove-shaped fitting 10 can also be made of non-woven fabric.

[0077] Examples of woven fabrics include: plain weave, twill weave, satin weave, and other commonly used weaves; weft knitting, warp knitting, lace knitting, and other commonly used knitting.

[0078] The threads (linear structures) that make up stretchable fabrics are insulating. Insulating threads are defined as those with a resistance of 1.0 × 10⁻⁶. 6 Wires with resistance greater than Ω / cm. The wire resistance of insulated wires is measured using the same method as that used for the wire resistance of conductive wires, as described later.

[0079] The stretchable fabric is preferably a woven fabric using elastic threads.

[0080] Examples of elastic yarns include: a covered yarn (single-layer or double-layer covered yarn) in which a non-elastic yarn is coiled around the periphery of the elastic yarn; a core-spun yarn in which the elastic and non-elastic yarns are twisted together; an air-wrapped covered yarn in which a non-elastic yarn is wound around the periphery of the elastic yarn using a compressed air nozzle; and a ply yarn made by twisting elastic and non-elastic yarns.

[0081] Examples of elastic fibers include polyurethane elastic fibers, polyester elastic fibers, and polyamide elastic fibers, which exhibit a so-called rubber-like elasticity.

[0082] Examples of non-elastic yarns include those made of synthetic fibers (polyester, polyamide, acrylic, polypropylene, rayon) and natural fibers (cotton, silk, linen, wool, etc.).

[0083] (Wire connection electrode section)

[0084] The wiring electrode section 100 includes an electrode section 20, a wiring section 30, and a wiring section 50.

[0085] The electrode section 20 has a first electrode section 20A and a second electrode section 20B, and is electrically connected to the communication module 202.

[0086] The wiring section 30 has a first wiring section 30A and a second wiring section 30B. When the part of the finger 2 opposite to the back of the hand of the proximal interphalangeal joint of the finger is extended or retracted due to the bending of the proximal interphalangeal joint of the finger (an example of the action of the device), the contact state of the first wiring section 30A and the second wiring section 30B changes (hereinafter referred to as "when the extension part of the finger 2 extends or retracts").

[0087] The wiring section 50 has a first wiring section 50A and a second wiring section 50B. The wiring section is used for connecting the electrode section 20 and the wiring section 30 (hereinafter, the wiring section 50 is referred to as the "connecting wiring section 50").

[0088] Furthermore, the wiring section 50 for connection is a wiring section provided as needed, or it can be a wiring section where the electrode section 20 is directly connected to the detection wiring section 30.

[0089] -Electrode Section-

[0090] In the electrode section 20, the first electrode section 20A and the second electrode section 20B are respectively provided on the back of the hand side of the wrist section 1 of the glove-shaped device section 10. However, the position of the electrodes is not particularly limited, and for example, it can be the palm side of the wrist section 1 of the glove-shaped device section 10 or the palm side of the main body section 3 of the glove-shaped device section 10.

[0091] Furthermore, the electrode section 20 may be configured with three or more depending on the purpose. For example, one electrode section may be made into a common electrode, and two or more wiring sections 50 may be connected to one electrode section. As an example, one may connect one of the two wiring sections 50 connected to the detection wiring section 30 disposed on the ring finger section 2D, and one of the two wiring sections 50 connected to the detection wiring section 30 disposed on the little finger section 2E, to one electrode section that serves as a common electrode.

[0092] like Figure 3 As shown, the electrode portion 20 is provided, for example, on the surface fabric layer 10A of the glove-shaped device portion 10. That is, the electrode portion 20 is provided on the surface of the glove-shaped device portion 10.

[0093] Furthermore, the electrode portion 20 can also be provided in the middle fabric layer 10C of the glove-shaped fitting portion 10. That is, the electrode portion 20 can be provided inside the glove-shaped fitting portion 10. This is because even if the electrode portion 20 is provided inside the glove-shaped fitting portion 10, it can be connected using pin-shaped electrodes or the like.

[0094] -Test wiring section-

[0095] The detection wiring section 30 is provided on the back of the hand of the finger section 2 opposite to the proximal interphalangeal joint of the finger (thumb section 2A, index finger section 2B, middle finger section 2C, ring finger section 2D, and little finger section 2E).

[0096] However, the configuration of the detection wiring section 30 is not limited to the above method, and may also be in the following manner depending on the purpose.

[0097] • The detection wiring section 30 is provided in a position on the back of the hand opposite to at least one of the proximal interphalangeal joint of the finger and the back of the hand opposite to the metacarpophalangeal joint of the finger.

[0098] • The detection wiring portion 30 is provided in a position on the finger portion 2 opposite to at least one of the palmar side of the proximal interphalangeal joint of the finger and the palmar side of the metacarpophalangeal joint.

[0099] • A portion of the multiple detection wiring portions 30 are positioned opposite the portion of the finger on the back side of the hand, while the remaining portion are positioned opposite the portion of the finger on the palm side. For example, the detection wiring portion 30 is positioned opposite the portion of the thumb 2A on the palm side of the thumb, and the detection wiring portion 30 is positioned opposite the portions of the index finger 2B, middle finger 2C, ring finger 2D, and little finger 2E on the back side of the hand, which are the portions of the index finger, middle finger, ring finger, and little finger.

[0100] • The detection wiring portion 30 is provided in at least one of the thumb portion 2A, index finger portion 2B, middle finger portion 2C, ring finger portion 2D, and little finger portion 2E.

[0101] In the detection wiring section 30, the first detection wiring section 30A is electrically connected to the first electrode section 20A. Additionally, the second detection wiring section 30B is electrically connected to the second electrode section 20B.

[0102] The first detection wiring section 30A and the second detection wiring section 30B are not integrated, and are configured to make at least a portion of them in contact before the extension portion of the finger 2 is extended.

[0103] However, when a portion of the detection wiring section 30 is positioned opposite the portion of the thumb 2A located on the palm side of the finger (for example, when the detection wiring section 30 is positioned opposite the portion of the thumb 2A located on the palm side of the thumb, or when the detection wiring section 30 is positioned opposite the portions of the index finger 2B, middle finger 2C, ring finger 2D, and little finger 2E located on the back side of the index finger, middle finger, ring finger, and little finger), in the position opposite the portion of the thumb 2A located on the palm side of the thumb, the first detection wiring section 30A and the second detection wiring section 30B are not integral and are set to be separated before the extension portion of the finger 2 is extended.

[0104] Furthermore, in the first modified example, it is explained that the first detection wiring section 30A and the second detection wiring section 30B are not integral and are configured to be separated in the state before the extension portion of the finger 2 is extended.

[0105] The first detection wiring section 30A extends, for example, along the length direction of the finger section 2. The first detection wiring section 30A has a wavy section 32A on which a conductive wire 40A2 is provided in a wavy manner.

[0106] The second detection wiring section 30B extends, for example, along the length direction of the finger section 2. The second detection wiring section 30B also has a wavy section 32B in which a conductive wire 40B2 is provided in a wavy manner.

[0107] Furthermore, before the extension portion of the finger 2 is extended, the corrugated portion 32A of the first detection wiring portion 30A and the corrugated portion 32B of the second detection wiring portion 30B are in point contact or line contact.

[0108] Furthermore, both the first detection wiring section 30A and the second detection wiring section 30B can have a structure that only has straight sections without the wavy sections of the conductive wires 40A2 and 40B2. Additionally, both the first detection wiring section 30A and the second detection wiring section 30B can have folded sections formed by bending the conductive wires 40A2 and 40B2.

[0109] The testing wiring section 30 is disposed inside the glove-shaped mounting section 10. Specifically, as follows: Figure 3 As shown, for example, by providing a detection wiring section 30 on the inner fabric layer (including fabric layers partially serving as the inner layer) of the glove-shaped device 10 composed of three fabric layers, i.e., the middle fabric layer 10C, the detection wiring section 30 can be provided inside the glove-shaped device 10. Alternatively, for example, the detection wiring section 30 can be provided between the fabric layers of the glove-shaped device 10 composed of two fabric layers.

[0110] Furthermore, the detection wiring portion 30 may also be provided on the surface of the glove-shaped device portion 10. For example, the detection wiring portion 30 may also be provided on the surface fabric layer 10A or the inner fabric layer 10B of the glove-shaped device portion 10, which is composed of three fabric layers. However, from the viewpoint of achieving insulation from the outside using the glove-shaped device portion 10, the detection wiring portion 30 is preferably provided inside the glove-shaped device portion 10.

[0111] -Connection wiring section 50-

[0112] In the connection wiring section 50, the first connection wiring section 50A electrically connects the first electrode section 20A and the first wiring section 30A. The second connection wiring section 50B electrically connects the second electrode section 20B and the second wiring section 30B.

[0113] The connecting wiring part 50 is provided on the main body 3 of the glove-shaped device part 10, which is opposite to the back of the hand.

[0114] However, the arrangement of the connection wiring section 50 is not limited to the above method, and can also be set according to the arrangement of the electrode section 20 and the detection wiring section 30.

[0115] The connecting wiring portion 50 is disposed inside the glove-shaped device portion 10. Specifically, for example, by providing the connecting wiring portion 50 on the inner fabric layer (including fabric layers partially serving as the inner layer) of the glove-shaped device portion 10, which is composed of three fabric layers, the connecting wiring portion 50 can be disposed inside the glove-shaped device portion 10. Alternatively, for example, the connecting wiring portion 50 can be disposed between the fabric layers of the glove-shaped device portion 10, which is composed of two fabric layers.

[0116] Furthermore, the connecting wiring portion 50 may also be provided on the surface of the glove-shaped device portion 10. For example, the connecting wiring portion 50 may also be provided on the surface fabric layer 10A or the inner fabric layer 10B of the glove-shaped device portion 10, which is composed of three fabric layers. However, from the viewpoint of achieving insulation from the outside using the glove-shaped device portion 10, the connecting wiring portion 50 is preferably provided inside the glove-shaped device portion 10.

[0117] -Conductive filament-

[0118] The electrode section 20, the detection wiring section 30, and the connection wiring section 50 each include a conductive wire 40. In other words, the areas where the conductive wires 40 are disposed are designated as the electrode section 20, the detection wiring section 30, and the connection wiring section 50.

[0119] Specifically, for example, the first electrode portion 20A includes a conductive linear body 40A1.

[0120] The first connection wiring section 50A includes a conductive wire 40A3 extending from the conductive wire 40A1 of the first electrode section 20A.

[0121] The first detection wiring section 30A includes a conductive wire 40A2 extending from the conductive wire 40A3 of the first connection wiring section 50A.

[0122] In other words, the first electrode section 20A and the first detection wiring section 30A are composed of at least the same conductive wire 40.

[0123] Additionally, for example, the second electrode portion 20B includes a conductive linear body 40B1.

[0124] The second connection wiring portion 50B includes a conductive wire 40B3 extending from the conductive wire 40B1 of the second electrode portion 20B.

[0125] The second detection wiring section 30B includes a conductive wire 40B2 extending from the conductive wire 40B3 of the second connection wiring section 50B.

[0126] In other words, the second electrode section 20B and the second detection wiring section 30B are each composed of at least one identical conductive wire 40.

[0127] The first electrode section 20A and the first detection wiring section 30A, the second electrode section 20B and the second detection wiring section 30B are each composed of the same conductive wire 40, thereby suppressing poor connection between the electrode section 20 and the detection wiring section 30.

[0128] Furthermore, the so-called identical conductive wire 40 also includes wires formed by joining the ends of the conductive wire 40 together by knotting or splicing without using other connecting materials (solder, conductive paste, etc.) or connecting components (riveting, connectors, etc.) other than wires.

[0129] However, the electrode section 20, the detection wiring section 30, and the connection wiring section 50 may each include multiple conductive wires 40. Furthermore, the first electrode section 20A, the first detection wiring section 30A, the first connection wiring section 50A, the second electrode section 20B, the second detection wiring section 30B, and the second connection wiring section 50B may not each be composed of the same single conductive wire 40.

[0130] For example, the ends of the conductive wires 40 of the first electrode section 20A, the first detection wiring section 30A, the first connection wiring section 50A, the second electrode section 20B, the second detection wiring section 30B, and the second connection wiring section 50B can also be connected to each other by other connecting materials (solder, conductive paste, etc.) or connecting components (riveting, connector, etc.) other than wires.

[0131] In at least one of the electrode section 20, the detection wiring section 30, and the connection wiring section 50, for example, at least a portion of the conductive wire 40 is constrained by the glove-shaped device section 10.

[0132] This method is preferred from the viewpoint that it can also be used as a means to fix the conductive wire 40, which functions as a conductive material, as an electrode part 20, a detection wiring part 30, and a connection wiring part 50 to the glove-shaped device part 10.

[0133] The conductive wire 40 constrained by the glove-shaped device 10 can be the same conductive wire 40 included in the electrode part 20, the detection wiring part 30 and the connection wiring part 50, or it can be a different conductive wire 40 included in any one of the electrode part 20, the detection wiring part 30 and the connection wiring part 50.

[0134] Furthermore, in at least one of the electrode section 20, the detection wiring section 30, and the connection wiring section 50, the conductive wire 40 may be exempt from the wire constraint of the glove-shaped mounting section 10.

[0135] For example, when at least one of the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 is fixed to the glove-shaped device portion 10 by adhesive, when at least one of the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 is sewn to the glove-shaped device portion 10 by insulating thread, even if the conductive wire body 40 is not constrained by the thread of the glove-shaped device portion 10, at least one of the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 can be fixed to the glove-shaped device portion 10.

[0136] For example, a rectangular region is formed in which the conductive linear body 40 is repeatedly folded or bent 180°. This rectangular region is formed by constraining a portion of the conductive linear body 40 to the thread of the surface fabric layer 10A of the glove-shaped mounting portion 10. Furthermore, this rectangular region is configured as a planar electrode portion 20.

[0137] Alternatively, the area where the conductive wires 40 are arranged in a spiral shape can be designated as the electrode section 20. Furthermore, any surface shape (polygon, circle, etc.) in which the conductive wires 40 are arranged in a bent or folded manner can be designated as the electrode section 20.

[0138] On the other hand, a region is formed in which the conductive wire 40 extends from the electrode portion 20 in a straight line, a wavy bend, or a combination thereof. This region is formed by constraining a portion of the conductive wire 40 to the thread of the intermediate fabric layer 10C of the glove-shaped fitting portion 10. Furthermore, this region serves as the detection wiring portion 30 and the connection wiring portion 50.

[0139] Specifically, when the glove-shaped fitting part 10 is made of fabric, such as Figure 7 As shown, in the weaving structure of a fabric woven with warp and weft threads, conductive linear bodies 40 are woven in to form an electrode section 20, a detection wiring section 30, and a connection wiring section 50. This method is preferred from the viewpoint that the glove-shaped device section 10, the electrode section 20, the detection wiring section 30, and the connection wiring section 50 can be formed simultaneously when the glove-shaped device section 10 is formed by weaving; and from the viewpoint of improving the integration of the glove-shaped device section 10, the electrode section 20, the detection wiring section 30, and the connection wiring section 50.

[0140] When the glove-shaped fitting part 10 is made of fabric, such as Figure 7As shown, in the braided structure of the fabric incorporating looped threads, conductive thread-like bodies 40 are woven in the above-described shape to form the electrode section 20, the detection wiring section 30, and the connection wiring section 50. This method is preferred from the viewpoint that the glove-shaped device section 10, the electrode section 20, the detection wiring section 30, and the connection wiring section 50 can be formed simultaneously when the glove-shaped device section 10 is formed by braiding; and from the viewpoint of improving the integration of the glove-shaped device section 10, the electrode section 20, the detection wiring section 30, and the connection wiring section 50.

[0141] When incorporating conductive linear bodies 40 into the web structure of a woven fabric, for example, straight weave, padded weave, intarsia weave, etc., can be used. Figure 7 This example illustrates the use of inlay weaving to incorporate conductive linear elements 40.

[0142] In addition, such as Figure 8 As shown, conductive wires 40 are embroidered on the glove-shaped device 10 in the above shape to form the electrode part 20, the detection wiring part 30, and the connection wiring part 50. This method is preferred from the viewpoint that when forming the electrode part 20, the detection wiring part 30, and the connection wiring part 50, the electrode part 20, the detection wiring part 30, and the connection wiring part 50 can also be fixed to the glove-shaped device 10 at the same time.

[0143] Embroidery methods include well-known stitches such as flat stitch, twill stitch, backstitch, chain stitch, and raised / relief stitch. Figure 8 This example illustrates the use of chain stitch to embroider conductive linear bodies 40.

[0144] Furthermore, the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 are fixed to the glove-shaped mounting portion 10 by sewing conductive wires 40. This method is preferred from the viewpoint that the conductive wires 40 constituting the electrode portion 20, the conductive wires 40 fixing the detection wiring portion 30, and the conductive wires 40 fixing the connection wiring portion 50 can be common components.

[0145] For example, as a method of fixing the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 by sewing the conductive thread 40, one example is to continuously form the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 from the fabric in which the conductive thread 40 is woven or knitted, and then sew the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 to the glove-shaped device portion 10 using the conductive thread 40.

[0146] exist Figure 6In the diagram, 12 represents the warp threads constituting the glove-shaped fitting part 10 (fabric), and 14 represents the weft threads constituting the glove-shaped fitting part 10 (fabric). Figure 7 In the text, 16 represents the thread that constitutes the glove-shaped fitting part 10 (fabric).

[0147] Furthermore, when an elastic thread is used as the thread constituting the glove-shaped device 10, it is preferable to form a braided fabric with the elastic thread stretched out, and to weave or knit the conductive thread 40 into the glove-shaped device 10.

[0148] (Conductive linear material)

[0149] The conductive wire that constitutes the electrode section 20, the detection wiring section 30, and the connection wiring section 50 is not particularly limited as long as it is conductive, and examples include wires containing metal wires and wires containing conductive wires. The conductive wire 40 may also be a wire containing both metal wires and conductive wires (such as a wire formed by twisting metal wires and conductive wires together).

[0150] Both wires containing metal wires and wires containing conductive wires have high conductivity. Therefore, when used as conductive wires 40, the resistance of the electrode section 20, the detection wiring section 30, and the connection wiring section 50 can be easily reduced.

[0151] Examples of metal wires include those containing metals such as copper, aluminum, tungsten, iron, molybdenum, nickel, titanium, silver, and gold, or alloys containing two or more metals (e.g., stainless steel, carbon steel, brass, phosphor bronze, zirconium copper alloy, beryllium copper, iron-nickel, nickel-chromium heat-resistant alloy, nickel-titanium, Cantal alloy, Hastelloy corrosion-resistant and heat-resistant nickel-based alloy, rhenium-tungsten, etc.). Furthermore, metal wires can be plated with tin, zinc, silver, nickel, chromium, nickel-chromium alloys, solder, etc., or their surface can be coated with carbon materials or polymers, as described later.

[0152] Examples of metal wires include those coated with carbon materials. Coating metal wires with carbon materials can inhibit metal corrosion.

[0153] Examples of carbon materials used to coat metal wires include amorphous carbon such as carbon black, activated carbon, hard carbon, soft carbon, mesoporous carbon, and carbon fiber; graphite; fullerene; graphene; and carbon nanotubes.

[0154] On the other hand, the linear body containing conductive wires can be a linear body composed of a single conductive wire, or a linear body composed of multiple conductive wires twisted together. Alternatively, it can be a linear body composed of conductive wires and insulating wires twisted together. Compared to linear bodies containing metal wires, linear bodies containing conductive wires are more flexible and have the advantage of being less prone to thread breakage caused by weaving, knitting, embroidering, or sewing into the glove-shaped fitting part 10.

[0155] Examples of conductive wires include wires containing conductive fibers (metal fibers, carbon fibers, fibers of ionically conductive polymers, etc.), wires containing conductive particles (carbon nanoparticles, etc.) (hereinafter referred to as carbon nanotube yarns), wires with metals (copper, silver, nickel, etc.) plated or vapor-deposited on their surface, and wires impregnated with metal oxides.

[0156] As a linear body containing conductive wires, a linear body containing carbon nanotube yarns (hereinafter also referred to as "carbon nanotube linear body") is particularly preferred.

[0157] Carbon nanotube filaments can be obtained, for example, by the following steps: drawing carbon nanotubes in sheet form from the ends of carbon nanotube clusters (multiple growths of carbon nanotubes on a substrate, oriented perpendicular to the substrate, also known as "arrays"), bundling the drawn carbon nanotube sheets, and then twisting the bundle of carbon nanotubes together. In this manufacturing method, a ribbon-like carbon nanotube filament is obtained without twisting during twisting, while a yarn-like filament is obtained with twisting. The ribbon-like carbon nanotube filament is a filament without a structure formed by twisting an assembly of multiple carbon nanotubes. Alternatively, carbon nanotube filaments can also be obtained from a dispersion of carbon nanotubes by spinning. The manufacture of carbon nanotube filaments using spinning can be performed by, for example, the method disclosed in US Publication No. US2013 / 0251619 (Japanese Patent Application Laid-Open No. 2011-253140). From the viewpoint of obtaining uniform diameter of carbon nanotube linear bodies, yarn-like carbon nanotube linear bodies are preferred. From the viewpoint of obtaining carbon nanotube linear bodies with high purity, yarn-like carbon nanotube linear bodies are preferred obtained by twisting carbon nanotube sheets. Carbon nanotube linear bodies can also be linear bodies formed by twisting two or more carbon nanotube linear bodies together.

[0158] Carbon nanotube linear bodies can also be linear bodies containing conductive materials other than carbon nanotubes, such as carbon nanotubes and metals, conductive polymers, and graphene (hereinafter also referred to as "composite linear bodies"). Composite linear bodies maintain the above-mentioned characteristics of carbon nanotube linear bodies and easily improve the conductivity of the linear bodies.

[0159] As a composite linear body, for example, a linear body containing carbon nanotubes and metal can be described as follows: (1) Carbon nanotubes are extracted from the ends of carbon nanotube clusters in sheet form, and the extracted carbon nanotube sheets are bundled together to obtain a carbon nanotube linear body formed by twisting the carbon nanotube bundles. In this process, a composite linear body is formed by bearing metal monomers or metal alloys on the surface of the carbon nanotube clusters, sheets or bundles, or the twisted linear body through evaporation, ion plating, sputtering, wet plating, etc.; (2) A composite linear body is formed by twisting carbon nanotube bundles together with a linear body of metal monomers or a linear body of metal alloys or a composite linear body; (3) A composite linear body is formed by twisting a linear body of metal monomers or a linear body of metal alloys or a composite linear body with a carbon nanotube linear body or a composite linear body, etc. Furthermore, for the composite linear body in (2), the metal can be supported on the carbon nanotubes in the same way as the composite linear body in (1) when twisting the bundle of carbon nanotubes. In addition, the composite linear body in (3) is a composite linear body with two linear bodies incorporated, but it is acceptable as long as it contains at least one metal monomer, metal alloy, or composite linear body. It is also possible to incorporate three or more carbon nanotube linear bodies, metal monomer linear bodies, metal alloy linear bodies, or composite linear bodies.

[0160] Metals that are composite linear bodies include, for example, metal monomers such as gold, silver, copper, iron, aluminum, nickel, chromium, tin, and zinc, and alloys containing at least one of these metal monomers (copper-nickel-phosphorus alloys, copper-iron-phosphorus-zinc alloys, etc.).

[0161] Among these conductive linear bodies 40, conductive linear bodies containing carbon nanotube yarns are preferred (especially conductive linear bodies containing only carbon nanotube yarns, or conductive linear bodies containing carbon nanotube yarns and non-metallic conductive materials).

[0162] For example, wires with metals (copper, silver, nickel, etc.) plated or vapor-deposited on their surface, or wires impregnated with metal oxides, are prone to cracking if repeatedly stretched or contracted, resulting in low durability. In this respect, carbon nanotube wires exhibit strong resistance to bending; even with repeated stretching and contraction of the finger portion 2, the resistance value of the wiring portion does not easily change. Furthermore, carbon nanotube wires also have the advantage of high corrosion resistance.

[0163] Here, the line resistance of the conductive wire 40 is preferably 5.0 × 10⁻⁶. -3 Ω / cm~1.0×10 3 Ω / cm, more preferably 1.0×10 Ω / cm -2 Ω / cm~5.0×10 2 Ω / cm.

[0164] The line resistance of the conductive wire 40 is measured as follows. First, silver paste is applied to both ends of the conductive wire 40, and the resistance of the portion between the silver pastes is measured to determine the resistance value of the conductive wire 40 (unit: Ω). Then, the obtained resistance value is divided by the distance (cm) between the silver pastes to calculate the line resistance of the conductive wire 40.

[0165] (Communication Module)

[0166] The communication module 202 is provided, for example, on the back of the hand side of the wrist portion 1 of the glove-shaped device 10. However, the configuration position of the communication module 202 is not particularly limited. For example, it can also be on the palm side of the wrist portion 1 of the glove-shaped device 10 or on the palm side of the main body portion of the glove-shaped device 10.

[0167] Furthermore, the communication module 202 is electrically connected to the electrode section 20 via a connection terminal not shown.

[0168] The communication module 202 is detachably mounted on the glove-shaped mounting part 10, for example, using a snap fastener. By removing the communication module 202 from the glove-shaped mounting part 10, the motion detection component 150 can be selected without waterproofing the communication module.

[0169] The communication module 202 includes a resistance detection unit 204 and a communication unit 206. Figure 5 In addition, the communication module 202 also has a power supply unit (not shown).

[0170] The resistance detection unit 204 is a sensor used to detect resistance values. The function of the resistance detection unit 204 is to detect the resistance values ​​of the first electrode 20A and the second electrode 20B. Furthermore, the resistance detection unit 204 transmits the detected resistance value to the communication unit 206. In this way, the resistance detection unit 204 detects the motion information of the device by utilizing the motion detection component 150 installed on the device.

[0171] Communication unit 206 is a communication device for wireless communication with server 300. When communicating directly with server 300, communication unit 206 follows standards such as IEEE 802.15.1 and IEEE 802.15.4. Furthermore, when communicating with server 300 via a wireless base station or wireless router, communication unit 206 follows standards such as Wi-Fi (registered trademark) and LTE, and communicates directly with the wireless base station or wireless router. Alternatively, communication unit 206 can also be configured to transmit the detected resistance value data to server 300 via a wired connection. The function of communication unit 206 is to transmit the resistance value data detected by resistance detection unit 204 to server 300.

[0172] (The function of motion detection components)

[0173] Regarding the motion detection component 150 of this embodiment, before the extension portion of the finger portion 2 in the glove-shaped mounting portion 10 is extended, at least a portion (in this embodiment, the wavy portions 32A and 32B) of the first detection wiring portion 30A and the second detection wiring portion 30B are in contact (see reference). Figure 4A Specifically, at least a portion of the conductive wire 40A2 constituting the first detection wiring portion 30A is in contact with the conductive wire 40B2 constituting the second detection wiring portion 30B.

[0174] On the other hand, when the extendable portion of the finger 2 in the glove-like device 10 is extended by bending the fingers (bending the proximal interphalangeal joint), at a certain elongation rate, the first detection wiring portion 30A and the second detection wiring portion 30B that are in contact separate (see reference). Figure 4B Specifically, the conductive wire 40A2 constituting the first detection wiring section 30A is separated from the conductive wire 40B2 constituting the second detection wiring section 30B.

[0175] More specifically, when the telescopic portion of the finger 2 extends, the period of the wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B becomes longer and the amplitude becomes smaller. As a result, the first detection wiring portion 30A and the second detection wiring portion 30B separate.

[0176] When the extension portion of finger 2 is lengthened due to this action, the resistance value between the first electrode portion 20A and the second electrode portion 20B changes. That is, the resistance value increases. Specifically, the connection between the first electrode portion 20A and the second electrode portion 20B changes from conductive to non-conductive.

[0177] Furthermore, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B as they extend, it is possible to detect finger movements (bending of the proximal interphalangeal joints of the fingers).

[0178] On the other hand, when the bending of the finger (bending of the proximal interphalangeal joint) is released and the elongation of the extension portion of the finger 2 is released (that is, when it contracts), at a certain elongation rate, at least a portion of the separated first detection wiring portion 30A and the second detection wiring portion 30B come into contact (refer to...). Figure 4A In other words, the resistance value decreases. Specifically, the connection between the first electrode portion 20A and the second electrode portion 20B changes from non-conductive to conductive.

[0179] In this way, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B that accompanies the extension and retraction, it is possible to detect the movement of the finger (the release of the bending of the proximal interphalangeal joint of the finger).

[0180] Here, regarding the telescopic portion of the finger 2 that has the maximum elongation (approximately 80%) (that is, the telescopic portion of the mounting portion where the detection wiring section is provided), in Figure 9 The image shows an example of the relationship between the resistance value between the first electrode 20A and the second electrode 20B and the measurement time, and the relationship between the elongation rate and the measurement time, when the extension portion of the finger 2 is extended to 70% at a speed of 1 mm / s five times and then retracted. Additionally, in... Figure 10 The text shows a diagram based on... Figure 9 An example of the relationship between the resistance value and elongation between the first electrode part 20A and the second electrode part 20B during the first stretching.

[0181] like Figures 9-10 As shown, regarding the telescopic portion of the finger 2 (that is, the telescopic portion of the mounting portion where the detection wiring portion is provided), when it telescopically extends or retracts, the resistance value between the first electrode portion 20A and the second electrode portion 20B changes at a certain elongation rate. Specifically, the first electrode portion 20A and the second electrode portion 20B change from being conductive to not conductive, and then from not conductive to conductive.

[0182] like Figures 9-10 As shown, the motion detection component 150 detects the movement of the finger (bending and releasing of the proximal interphalangeal joint of the finger) by detecting the change in resistance between the first electrode 20A and the second electrode 20B caused by the extension and retraction of the extension and retraction part of the finger 2 (that is, the extension and retraction part of the mounting part where the detection wiring part is provided).

[0183] In addition, according to Figures 9-10 The measurement results of the resistance value change shown indicate that, within an average elongation range of approximately 43.7% ± 5%, the resistance value increases during elongation and decreases during contraction.

[0184] (server)

[0185] Next, the server 300 will be described. The server 300 displays the state of the hand (e.g., rock, paper, scissors) based on the resistance value detected by the motion detection component 150. That is, the motion detection component 150 can detect finger movements; therefore, in the motion detection system 1000 of this embodiment, the motion detection component 150 functions as an input device for displaying the state of the hand. Furthermore, the server 300 can not only display the state of the hand but also output a sound explaining the state of the hand.

[0186] (Server structure)

[0187] Figure 11This is a block diagram illustrating the hardware structure of the server 300 in this embodiment. For example... Figure 11 As shown, server 300 includes: CPU (Central Processing Unit) 301, ROM (Read Only Memory) 302, RAM (Random Access Memory) 303, storage device 304, input unit 305, display unit 306, and antenna 307. All components are interconnected via bus 309 in a communicable manner. Server 300 can be a general-purpose computer, or various information processing devices such as smartphones and tablets.

[0188] CPU 301 is the central processing unit, which executes various programs and controls various components. Specifically, CPU 301 reads programs from ROM 302 or storage device 304 and uses RAM 303 as its working area to execute the programs. CPU 301 performs control of the aforementioned structures and various arithmetic operations according to the programs stored in ROM 302 or storage device 304. In this embodiment, an action detection program is stored in ROM 302 or storage device 304.

[0189] ROM 302 stores various programs and data. RAM 303 serves as a working area to temporarily store programs or data. Storage device 304 is composed of storage devices such as HDD (Hard Disk Drive) or SSD (Solid State Drive), storing various programs including the operating system and various data.

[0190] The input unit 305 includes a pointing device such as a mouse and a keyboard for various input operations.

[0191] Display unit 306 is, for example, an LCD display that shows various information. Display unit 306 adopts a touch panel method and can function as an input unit 305.

[0192] Antenna 307 is an antenna used for wireless communication with other devices including motion detection component 150. When communicating directly with other devices, it conforms to standards such as IEEE 802.15.1 and IEEE 802.15.4. Furthermore, when communicating with other devices via wireless base stations or wireless routers, antenna 307 can employ standards such as Wi-Fi (registered trademark) and LTE.

[0193] Next, the functional structure of server 300 will be explained. Figure 12 This is a block diagram illustrating an example of the functional structure of server 300. For example... Figure 12As shown, the server 300, as a functional structure, includes: a communication unit 311, an action determination unit 312, an image generation unit 313, and a display unit 314. Each functional structure can be implemented by the CPU 301 reading the action detection program stored in the ROM 302 or the storage device 304 and executing it in the RAM 303.

[0194] The communication unit 311 receives the resistance value from the motion detection component 150. Furthermore, the communication unit 311 transmits the received resistance value to the motion determination unit 312.

[0195] The action determination unit 312 determines whether the installed body has been activated based on the resistance value received from the communication unit 206.

[0196] Specifically, when the difference between the specified resistance value and the resistance value detected by the resistance detection unit 204 is above a specified threshold, the action determination unit 312 determines that the finger has moved.

[0197] Here, the motion determination unit 312 determines whether each finger is moving. To determine which finger is moving, the following structure is adopted: resistance value data and information indicating which finger it is are received in advance from the motion detection unit 150. The motion determination unit 312 determines whether each finger is moving based on the resistance values ​​detected by the resistance detection unit 204, which is configured for each finger, and determines the hand movement based on the combination of determination results. For example, the motion determination unit 312 determines whether there is movement at the proximal interphalangeal joint and whether there is movement at the metacarpophalangeal joint. Furthermore, the motion determination unit 312 transmits the determination results to the image generation unit 313.

[0198] The image generation unit 313 generates an image corresponding to the determined action based on the determination result of the action determination unit 312. Specifically, when the image generation unit 313 determines that there is action at the proximal interphalangeal joint, it generates an image showing the proximal interphalangeal joint bending. Alternatively, the image generation unit 313 may select a corresponding image from a predetermined set of images representing hand actions. The image generation unit 313 then transmits the generated image to the display unit 314.

[0199] Display unit 314 displays strings, images, or motion graphics corresponding to the actions generated by image generation unit 313, plays sound, or outputs control signals for controlling devices operating according to the actions. Specifically, display unit 314 displays strings, images, motion graphics, or sound corresponding to the actions, or control signals for controlling devices operating according to the actions in display unit 306. When outputting strings or sound, display unit 314 outputs the string corresponding to the action or the result of converting the string into sound. Furthermore, control signals may include, for example, input information for IoT-based control such as IFTTT, or control signals for vehicle steering wheels or robots. In this case, server 300 communicates with or directly connects to other devices.

[0200] (The role of a server)

[0201] Explain the function of server 300. Figure 13 This is a flowchart illustrating the motion detection processing flow of server 300. CPU 301 reads the motion detection program from ROM 302 or storage device 304 and executes it in RAM 303 to process the server 300.

[0202] In step S101, the CPU 301, acting as the communication unit 311, receives the resistance value from the motion detection unit 150.

[0203] In step S102, the CPU301, as the action determination unit 312, determines whether the installed body has an action based on the resistance value received from the communication unit 206.

[0204] In step S103, the CPU301, as the image generation unit 313, generates an image corresponding to the action determined by the action determination unit 312.

[0205] In step S104, the CPU 301, acting as the display unit 314, displays an image corresponding to the action generated by the image generation unit 313, and the processing ends. This process is repeated each time a resistance value is received. Alternatively, a structure can be adopted in which the process determines at predetermined intervals whether a resistance value has been received, and performs the processing if it has been received.

[0206] As described above, the motion detection system disclosed herein includes: a motion detection unit, a communication unit, and a motion determination unit. The motion detection unit detects motion information of the installed body by means of a motion detection component installed on the installed body. The communication unit sends the motion information detected by the motion detection unit to a server. The motion determination unit determines what kind of action the motion information is, thereby providing a motion detection system that can accurately detect what action the installed body has performed.

[0207] Furthermore, the motion detection component includes: a mounting part that is mounted on a device and has a telescopic portion that extends and retracts due to the movement of the device; and a wiring electrode part that detects extension and retraction information indicating that extension and retraction has occurred when the telescopic portion of the mounting part extends and retracts. Therefore, the motion detection component has excellent mounting feel, so the user will not feel any discomfort when there is movement, and the motion detection component has little impact on the movement. This allows for more accurate motion detection.

[0208] Furthermore, the server determines whether the device is moving based on the resistance value received from the communication unit, thus enabling the detection of any range of motion. By preparing multiple thresholds, multi-stage motion detection is also possible.

[0209] Furthermore, by displaying images or dynamic images corresponding to the movements, the state of the device can be monitored in real time. This allows for applications such as rehabilitation training and motion confirmation of robotic arms.

[0210] Furthermore, because it can display strings, images, or animated images corresponding to actions, play sounds, or output control signals for controlling devices that operate based on actions, it can also convert sign language into text or sound for recognition. It can also be applied to training sign language, etc.

[0211] Furthermore, by using the aforementioned telescopic sensor, motion detection components with high durability and excellent fit can be used for motion detection. In other words, a motion detection system can be provided that has excellent fit and can accurately detect hand movements.

[0212] (Modified example of the wiring electrode section)

[0213] In the motion detection component 150 of this embodiment, the wiring electrode section is not limited to the structure of the wiring electrode section 100 shown in FIG4, and can be modified or improved.

[0214] Hereinafter, a modified example of the wiring electrode section in the motion detection component of this embodiment will be described.

[0215] Furthermore, in the following description, if the wiring electrode section is the same as the component described above, the same reference numerals will be used in the figures and its description will be omitted or simplified.

[0216] In addition, the wiring section for connection will be omitted in the following description.

[0217] -First Variation-

[0218] For example, the wiring electrode section can be Figure 14A The wiring electrode section 101 shown.

[0219] Specifically, such as Figure 14A As shown, regarding the wiring electrode section 101, before the extension portion of the mounting section of the detection wiring section 30 (hereinafter referred to as the "extension portion of the mounting section") is extended, the first detection wiring section 30A and the second detection wiring section 30B are separately disposed. Furthermore, the corrugated portion 32A of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B are substantially parallel to each other and separately disposed.

[0220] When the telescopic portion of the mounting part extends due to the movement of the mounted body, at a certain elongation rate, at least a portion of the separated first detection wiring portion 30A and second detection wiring portion 30B come into contact (refer to...). Figure 14B Specifically, at least a portion of the conductive wire 40A2 constituting the first detection wiring portion 30A is in contact with the conductive wire 40B2 constituting the second detection wiring portion 30B.

[0221] More specifically, when the telescopic part of the mounting section extends, the period of the corrugated part 32A of the first detection wiring section 30A and the corrugated part 32B of the second detection wiring section 30B becomes longer and the amplitude becomes smaller, and they approach and contact each other.

[0222] When the telescopic portion of the mounting unit extends due to this action, the resistance value between the first electrode portion 20A and the second electrode portion 20B changes. That is, the resistance value decreases. Specifically, the connection between the first electrode portion 20A and the second electrode portion 20B changes from non-conductive to conductive.

[0223] Furthermore, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B as they extend, the movement of the installed body can be detected.

[0224] On the other hand, when the extension portion of the mounting part is released due to the movement of the mounted body (that is, when it retracts), at a certain elongation rate, the first detection wiring portion 30A and the second detection wiring portion 30B that were in contact separate (see reference). Figure 14A In other words, the resistance value increases. Specifically, the connection between the first electrode 20A and the second electrode 20B changes from conductive to non-conductive.

[0225] In this way, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B that accompanies contraction, the movement of the installed body can be detected.

[0226] -Second Variation-

[0227] For example, the wiring electrode section can be Figure 15A The wiring electrode section 102 shown.

[0228] Specifically, such as Figure 15A As shown, the wiring electrode section 102 has a first corrugated section 32A1 and a second corrugated section 32A2 as the corrugated section 32A of the first detection wiring section 30A. The second corrugated section 32A2 has a different contact length than the first corrugated section 32A1 and the corrugated section 32B of the second detection wiring section 30B.

[0229] Furthermore, the wiring electrode section 102 serves as the wavy section 32A of the first detection wiring section 30A, and has a first wavy section 32A1 and a second wavy section 32A2, the second wavy section 32A2 having a different period and / or amplitude than the first wavy section 32A1.

[0230] Furthermore, in this example, an example is shown where the contact length between the second corrugated portion 32A2 and the corrugated portion 32B of the second detection wiring portion 30B is shorter than that of the first corrugated portion 32A1. Also, an example is shown where the second corrugated portion 32A2 has a shorter period and smaller amplitude than the first corrugated portion 32A1.

[0231] When the telescopic portion (hereinafter referred to as "telescopic portion of the device") of the mounting part equipped with the detection wiring section 30 is extended due to the movement of the mounted body, at a certain elongation rate, a portion of the first detection wiring section 30A and the second detection wiring section 30B that are in contact separate (see reference). Figure 15B Specifically, the second corrugated portion 32A2 of the first detection wiring section 30A is separated from the corrugated portion 32B of the second detection wiring section 30B.

[0232] When further elongated, at a certain elongation rate, the second corrugated portion 32A2 of the first detection wiring portion 30A separates from the corrugated portion 32B of the second detection wiring portion 30B (see reference). Figure 15C ).

[0233] In other words, the second corrugated portion 32A2 of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B separate first, and the first corrugated portion 32A1 of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B separate later.

[0234] When the telescopic portion of the mounting section extends due to this action, the resistance value between the first electrode portion 20A and the second electrode portion 20B changes in stages. That is, the resistance value increases in stages by the amount corresponding to the increase in contact resistance caused by the partial separation of the first detection wiring portion 30A and the second detection wiring portion 30B. Specifically, when the first electrode portion 20A and the second electrode portion 20B are in a conductive state, after the resistance value increases by a certain value, the conductive state changes to a non-conductive state.

[0235] Furthermore, by detecting the phased changes in the resistance value between the first electrode portion 20A and the second electrode portion 20B as they elongate, it is possible to detect the phased movement of the installed body.

[0236] On the other hand, when the extension of the telescopic part of the mounting section is released due to the movement of the mounted body (that is, when it contracts), at a certain elongation rate, the first corrugated portion 32A1 of the separated first detection wiring section 30A comes into contact with the corrugated portion 32B of the second detection wiring section 30B (see reference). Figure 15B ).

[0237] Furthermore, during contraction, at the moment a certain elongation is reached, the second corrugated portion 32A2 of the separated first detection wiring portion 30A contacts the corrugated portion 32B of the second detection wiring portion 30B (see reference). Figure 15A In other words, the resistance value decreases in stages.

[0238] Specifically, when the first electrode portion 20A and the second electrode portion 20B change from non-conductive to conductive, the resistance value decreases in the conductive state.

[0239] In this way, by detecting the phased changes in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompany contraction, it is possible to detect the phased movement of the installed body.

[0240] Regarding the second modification, based on the phased change in resistance value between the first electrode portion 20A and the second electrode portion 20B for the purpose of detection, multiple regions with different contact lengths may be formed at the contact portion between the corrugated portion 32A of the first detection wiring portion 30A and the corrugated portion 32B of the second detection wiring portion 30B. Furthermore, at least one of the first detection wiring portion 30A and the second detection wiring portion 30B may have multiple corrugated portions with different periods and / or amplitudes.

[0241] Furthermore, the so-called phased change in resistance value (that is, phased increase or decrease) refers to the change in resistance value during the extension of the telescopic part of the mounting section, and the change in resistance value again once the change in resistance value ends.

[0242] -Third Variation-

[0243] For example, the wiring electrode section can be Figure 16A The wiring electrode section 103 is shown. Specifically, as... Figure 16A As shown, the wiring electrode section 103, as an electrode section 20, also has a third electrode section 20C, and the wiring section 30, as a detection wiring section, also has a third detection wiring section 30C.

[0244] The third electrode section 20C includes a conductive wire 40C1. The third detection wiring section 30C includes a conductive wire 40C2 extending from the conductive wire 40C1 of the third electrode section 20C. That is, the third electrode section 20C and the third detection wiring section 30C are both composed of at least one identical conductive wire 40.

[0245] The third detection wiring section 30C is electrically connected to the third electrode section 20C.

[0246] The third detection wiring section 30C is configured to be non-integrated with the first detection wiring section 30A and the second detection wiring section 30B, and in the state before the extension portion of the mounting section where the detection wiring section 30 is provided (hereinafter referred to as the "extension portion of the mounting section") is extended, it is sandwiched between the first detection wiring section 30A and the second detection wiring section 30B, and is in contact with at least a portion of the first detection wiring section 30A and the second detection wiring section 30B.

[0247] The third detection wiring section 30C, for example, has a wavy section 32C in which a conductive wire 40C2 is provided in a wavy manner.

[0248] Furthermore, before the telescopic portion of the mounting section extends, the corrugated portion 32C of the third detection wiring section 30C makes point contact or line contact with the corrugated portion 32A of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B.

[0249] However, the contact lengths of the corrugated portion 32C of the third detection wiring section 30C and the corrugated portion 32A of the first detection wiring section 30A are different from the contact lengths of the corrugated portion 32C of the third detection wiring section 30C and the corrugated portion 32B of the second detection wiring section 30B. Furthermore, the periods and / or amplitudes of the corrugated portion 32C of the third detection wiring section 30C, the corrugated portion 32A of the first detection wiring section 30A, and the corrugated portion 32B of the second detection wiring section 30B are different.

[0250] Furthermore, this example shows an instance where the contact length between the corrugated portion 32C of the third detection wiring section 30C and the corrugated portion 32A of the first detection wiring section 30A is shorter than the contact length between the corrugated portion 32C of the third detection wiring section 30C and the corrugated portion 32B of the second detection wiring section 30B. Also, an example is shown where the amplitude of the corrugated portion 32C of the third detection wiring section 30C is smaller than that of the corrugated portion 32A of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B.

[0251] When the telescopic part of the mounting section extends, at a certain elongation rate, the first detection wiring section 30A and the third detection wiring section 30C that were in contact separate (see reference). Figure 16BSpecifically, the corrugated portion 32A of the first detection wiring section 30A is separated from the corrugated portion 32C of the third detection wiring section 30C.

[0252] As it elongates further, at a certain elongation rate, the second detection wiring section 30B and the third detection wiring section 30C separate (see reference). Figure 16C Specifically, the corrugated portion 32B of the second detection wiring section 30B is separated from the corrugated portion 32C of the third detection wiring section 30C.

[0253] In other words, the first detection wiring section 30A and the third detection wiring section 30C separate first, and the second detection wiring section 30B and the third detection wiring section 30C separate later.

[0254] When the telescopic portion of the mounting unit extends due to this action, the resistance value between the first electrode portion 20A and the third electrode portion 20C changes. That is, the resistance value increases. Specifically, the connection between the first electrode portion 20A and the third electrode portion 20C changes from conductive to non-conductive.

[0255] As it stretches further, the resistance between the second electrode portion 20B and the third electrode portion 20C changes. That is, the resistance increases. Specifically, the connection between the second electrode portion 20B and the third electrode portion 20C changes from conductive to non-conductive.

[0256] Furthermore, by detecting the change in resistance between the first electrode portion 20A and the third electrode portion 20C, and the change in resistance between the second electrode portion 20B and the third electrode portion 20C, which occur during elongation, the movement of the installed body can be detected.

[0257] On the other hand, when the extension of the telescopic part of the device is released due to the movement of the device (that is, when it retracts), at a certain elongation rate, the separated second detection wiring part 30B and the third detection wiring part 30C come into contact (see reference). Figure 16B Specifically, the corrugated portion 32B of the second detection wiring section 30B contacts the corrugated portion 32C of the third detection wiring section 30C.

[0258] When further contraction occurs, at a certain elongation, the separated first detection wiring section 30A and the third detection wiring section 30C come into contact (refer to...). Figure 16A Specifically, the corrugated portion 32A of the first detection wiring section 30A contacts the corrugated portion 32C of the third detection wiring section 30C.

[0259] In other words, the second detection wiring section 30B and the third detection wiring section 30C make contact first, and the first detection wiring section 30A and the third detection wiring section 30C make contact later.

[0260] In this way, by detecting the change in resistance between the first electrode portion 20A and the third electrode portion 20C, and the change in resistance between the second electrode portion 20B and the third electrode portion 20C, which are accompanied by contraction, it is possible to detect the phased movement of the installed body.

[0261] In addition, the third variation can also be as follows: the second detection wiring section 30B and the third detection wiring section 30C are separated first, and the first detection wiring section 30A and the third detection wiring section 30C are separated later.

[0262] -Fourth Variation-

[0263] For example, the wiring electrode section can be Figure 17A The wiring electrode section 104 shown.

[0264] Specifically, such as Figure 17A As shown, regarding the wiring electrode section 104, before the extension portion of the mounting section (hereinafter referred to as the "extension portion of the mounting section") where the detection wiring section 30 is provided is extended, the first detection wiring section 30A and the second detection wiring section 30B are separately provided. Furthermore, the corrugated portion 32A of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B are facing each other at an angle (for example, the angle formed by the extension directions of each corrugated portion is 3° to 30°) and are separately provided.

[0265] When the telescopic portion of the mounting part extends due to the movement of the mounted body, at a certain elongation rate, at least a portion of the separated first detection wiring portion 30A and second detection wiring portion 30B come into contact (refer to...). Figure 17B Specifically, at least a portion of the conductive wire 40A2 constituting the first detection wiring portion 30A is in contact with the conductive wire 40B2 constituting the second detection wiring portion 30B.

[0266] More specifically, when the telescopic portion of the mounting section extends, the period of the corrugated portion 32A of the first detection wiring section 30A and the period of the corrugated portion 32B of the second detection wiring section 30B become longer and the amplitude becomes smaller, and the corrugated portion 32B of the second detection wiring section 30B approaches and contacts the corrugated portion 32A of the first detection wiring section 30A from the front end side (the front end side of the one not connected to the second electrode section 20B).

[0267] As it extends further, the contact area between the first detection wiring section 30A and the second detection wiring section 30B increases (see reference). Figure 17C Specifically, the contact area between the conductive wire 40A2 constituting the first detection wiring section 30A and the conductive wire 40B2 constituting the second detection wiring section 30B is increased.

[0268] More specifically, when the telescopic part of the mounting section extends, the period of the corrugated portion 32A of the first detection wiring section 30A and the corrugated portion 32B of the second detection wiring section 30B becomes longer and the amplitude becomes smaller, and they become closer together, thus increasing the contact area.

[0269] When the telescopic portion of the mounting section extends due to this action, the resistance value between the first electrode portion 20A and the second electrode portion 20B changes in stages. That is, when the first detection wiring portion 30A and the second detection wiring portion 30B first come into contact, the first electrode portion 20A and the second electrode portion 20B change from a non-conductive state to a conductive state. Then, as the contact area between the first detection wiring portion 30A and the second detection wiring portion 30B increases, the contact resistance decreases, and the resistance value between the first electrode portion 20A and the second electrode portion 20B decreases in stages.

[0270] Furthermore, by detecting the phased changes in the resistance value between the first electrode portion 20A and the second electrode portion 20B as they elongate, it is possible to detect the phased movement of the installed body.

[0271] On the other hand, when the extension of the telescopic part of the device is released due to the movement of the device (that is, when it retracts), the contact area between the first detection wiring part 30A and the second detection wiring part 30B is reduced. Figure 17B Furthermore, during contraction, at the moment a certain elongation is reached, the first corrugated portion 32A1 of the first detection wiring portion 30A and the corrugated portion 32B of the second detection wiring portion 30B separate (see reference). Figure 17A In other words, the resistance value increases in stages.

[0272] Specifically, when the first electrode 20A and the second electrode 20B are in a conductive state, the resistance value decreases, and then the state becomes non-conductive.

[0273] In this way, by detecting the phased changes in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompany the contraction, the phased movement of the installed body can also be detected.

[0274] - Fifth variation -

[0275] For example, the wiring electrode section can be Figure 18A The wiring electrode section 105 is shown. Specifically, as shown... Figure 18AAs shown, in the wiring electrode section 105, a first detection wiring section 30A and a second detection wiring section 30B are integrally provided as a detection wiring section 30. Specifically, for example, the first detection wiring section 30A and the second detection wiring section 30B, which are detection wiring sections 30, are composed of a single conductive wire 40, which extends from the conductive wire 40 constituting the first electrode section 20A and the second electrode section 20B.

[0276] In other words, in the wiring electrode section 105, the first electrode section 20A and the second electrode section 20B are electrically connected by a detection wiring section 30.

[0277] Furthermore, the detection wiring section 30 can be composed of multiple conductive wires 40.

[0278] The detection wiring section 30 has a contact section 34 in the middle, which is formed when the extension portion of the mounting portion of the detection wiring section 30 (hereinafter referred to as "the extension portion of the mounting portion") is extended, and the detection wiring section 30 is repeatedly bent or bent 180° and at least a portion of the detection wiring sections 30 between the bent or bent portions come into contact with each other.

[0279] In other words, the detection wiring section 30 has a contact section 34 such that, in the state before the extension portion of the mounting section is extended, the conductive wire 40 is repeatedly bent or bent 180° and at least a portion of the conductive wire 40 between the bent or bent portions comes into contact with each other to form the contact section 34.

[0280] When the telescopic portion of the mounting section extends along the extending direction of the detection wiring section 30, the detection wiring sections 30 that are in contact between the bent or curved portions separate from each other (see reference). Figure 18B As a result, the conduction path between the first electrode section 20A and the second electrode section 20B becomes longer.

[0281] When the telescopic portion of the mounting section extends due to this action, the resistance between the first electrode portion 20A and the second electrode portion 20B changes. In other words, the resistance increases by an amount corresponding to the increase in the conduction path.

[0282] Furthermore, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B as they extend, the movement of the installed body can be detected.

[0283] On the other hand, when the extension of the telescopic portion of the mounting part is released due to the movement of the mounted body (that is, when it retracts), a contact portion 34 is formed along the path of the detection wiring portion 30. For this contact portion 34, the detection wiring portion 30 is repeatedly bent or folded 180°, and at least a portion of the bent or folded detection wiring portions 30 contacts each other to form the contact portion 34 (see reference). Figure 18A ).

[0284] When the telescopic part of the mounting section retracts due to this action, the resistance value between the first electrode part 20A and the second electrode part 20B changes. That is, the resistance value decreases by the amount corresponding to the reduction in the conduction path.

[0285] Furthermore, the movement of the installed body can also be detected by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B as they contract.

[0286] Furthermore, in the fifth modification, by increasing or decreasing the contact area between the detection wiring portions 30 and the contact portions of the detection wiring portions 30, the amount of change in the resistance value between the first electrode portion 20A and the second electrode portion 20B can be controlled.

[0287] -Sixth variation-

[0288] The electrode wiring section can be, for example, Figure 19 The wiring electrode section 106 shown. That is, it can be arranged in the following manner: the telescopic part of the glove-shaped device section on which the detection wiring section is provided is disposed on the surface of the glove-shaped device section at the corresponding position.

[0289] Specifically, such as Figure 19 As shown, the wiring electrode section 106 (electrode section 20, detection wiring section 30, and connection wiring section 50) is provided on the elastic fabric 60.

[0290] The stretchable fabric 60 is composed of three layers: a surface fabric layer 60A forming the surface, an inner fabric layer 60B forming the inner surface, and an intermediate fabric layer 60C located between the surface fabric layer 60A and the inner fabric layer 60B. Furthermore, the structure of the stretchable fabric 60 is the same as that of the fabric constituting the glove-shaped fitting part 10.

[0291] Electrode portion 20 is provided, for example, on the surface fabric layer 60A of elastic fabric 60.

[0292] The detection wiring section 30 is provided, for example, in the middle fabric layer 60C of the elastic fabric 60.

[0293] Wiring section 50 is provided, for example, in the middle fabric layer 60C of elastic fabric 60.

[0294] Furthermore, the elastic fabric 60, which is provided with the wiring electrode section 106, is disposed on the surface of the glove-shaped device section 10 at the corresponding position by known fixing methods such as sewing and bonding.

[0295] In the sixth variation, since the elastic fabric 60 on which the wiring electrode part 106 is provided is disposed on the surface of the glove-shaped device part 10 at the corresponding position, the glove-shaped device part 10 can be made of known materials such as resin, paper, and leather in addition to fabric.

[0296] -Seventh Variation-

[0297] The electrode wiring section can be, for example, Figure 20 The wiring electrode section 107 shown. That is, it can be arranged in the following manner: the telescopic part of the glove-shaped device section on which the detection wiring section is provided is disposed on the surface of the glove-shaped device section at the corresponding position.

[0298] Specifically, such as Figure 20 As shown, as the electrode part 20, the button electrode (button, etc.) is disposed on the surface of the glove-shaped mounting part 10 at the corresponding position by known fixing methods such as sewing and bonding.

[0299] The testing wiring section 30 is provided on the elastic fabric 70.

[0300] The stretchable fabric 70 is composed of three layers: a surface fabric layer 70A forming the surface, an inner fabric layer 70B forming the inside, and an intermediate fabric layer 70C located between the surface fabric layer 70A and the inner fabric layer 70B. Furthermore, the structure of the stretchable fabric 70 is the same as that of the fabric constituting the glove-shaped fitting part 10.

[0301] Furthermore, a stretchable fabric 70 with a detection wiring section 30 is provided on the surface of the glove-shaped device section 10.

[0302] A connection wiring section 50 is provided on the surface of the glove-shaped mounting section 10, and connects the electrode section 20 to the detection wiring section 30. In addition, the connection wiring section 50 is covered with an insulating sheet 72 made of a known material such as cloth or resin.

[0303] In the seventh variation, since the wire electrode portion 107 is disposed on the surface of the glove-shaped device portion 10 at the corresponding position, the glove-shaped device portion 10 can be made of known materials such as resin, paper, and leather, in addition to cloth.

[0304] (characteristic)

[0305] Furthermore, in order to detect the movement of the installed body, for the telescopic portion of the installation part (hereinafter referred to as "telescopic portion of the installation part") where the detection wiring part 30 is provided, it is preferable to have an elongation range as follows: within a range of ±5% change in elongation, the resistance value between the first electrode part 20A and the second electrode part 20B becomes more than twice or less than half (preferably more than ten times or less than one-tenth, more preferably more than one hundred times or less than one-hundredth) (refer to...). Figures 7-8 In other words, for the telescopic part of the mounting section, preferably, during the elongation process, during the period when the elongation rate changes by 10%, the resistance value between the first electrode part 20A and the second electrode part 20B becomes more than twice or less than half.

[0306] Specifically, when the maximum elongation rate of the telescopic part of the mounting part is set to X (where 10≦X) and the elongation rate at a certain position when the telescopic part of the mounting part is elongated is set to Y (where 5≦Y≦(X-5)), there is a region in the range of Y-5% to Y+5% where the maximum resistance value is more than twice or less than half of the minimum resistance value (preferably more than 10 times or less than 1 / 10, more preferably more than 100 times or less than 1 / 100).

[0307] The resistance change is calculated by the ratio of the resistance value at the moment when the elongation reaches the target to the resistance value at the moment when the elongation changes by 10%.

[0308] Furthermore, within a range of ±5% elongation variation, there may be two or more locations where the resistance value between the first electrode portion 20A and the second electrode portion 20B changes to more than twice or less than half of the elongation.

[0309] Furthermore, within a range of ±5% in the elongation rate variation, the ratio of the elongation rate to the maximum elongation rate (elongation rate / maximum elongation rate) where the resistance value between the first electrode portion 20A and the second electrode portion 20B becomes more than twice or less than half can be in the range of 0.1 to 0.9 (preferably 0.2 to 0.8). If this ratio is within the above range, malfunctions can be prevented, and the movement of the installed body can be detected efficiently.

[0310] The change in resistance between the first electrode 20A and the second electrode 20B as the extension and retraction of the mounting section is performed as follows.

[0311] While measuring the resistance between the first electrode 20A and the second electrode 20B, the telescopic part of the mounting part is extended to its maximum extension at a speed of 1 mm / s, and then retracted at the same speed. During this process, the resistance value is calibrated every 1 second, and the change in resistance value is measured. Furthermore, the extension direction of the telescopic part of the mounting part is the direction in which the change in resistance value caused by the extension and retraction is to be detected.

[0312] Here, the elongation rate of the telescopic part of the mounting section can be calculated by the following formula: ((length in the elongation direction during elongation) - (length in the elongation direction before elongation)) / (length in the elongation direction before elongation) × 100.

[0313] On the other hand, the maximum elongation rate of the telescopic part of the mounting section can be calculated by the following formula: ((length in the elongation direction at maximum elongation) - (length in the elongation direction before elongation)) / (length in the elongation direction before elongation) × 100.

[0314] Furthermore, the maximum elongation of the telescopic part of the mounting unit refers to the length at which it no longer elongates when the telescopic part of the mounting unit is stretched with appropriate tension. In other words, the maximum elongation of the telescopic part of the mounting unit is set as the length at which the telescopic part of the mounting unit extends using the tension at which elongation stops.

[0315] (The shape of the motion detection component (its mounting part), etc.)

[0316] In the above embodiment, the example described is that the mounting part of the motion detection component 150 is glove-shaped, but it is not limited to this. Depending on the purpose of motion detection, the shape of the mounting part can be various, such as cylindrical, sheet-like, or strip-like.

[0317] As a cylindrical mounting part, it can take the shape of a knee pad, wristband, etc. As a sheet-like mounting part, it can take the shape of a knee pad, wristband, etc., with buckles at both ends and wrapped around the body to be mounted. Furthermore, in the case of a sheet-like mounting part, it can be glued to the body using adhesive. As a strip-like mounting part, it can take the shape of a sling, etc. Moreover, the shape of the mounting part can be selected according to its mounting position on the body to be mounted.

[0318] Here, the location on the object to be installed can be, for example, the movable parts of a human body (neck, wrist, elbow, shoulder, knee, waist, ankle, foot, etc.). However, it is not limited to these. If it is not a human body, it can be the arm of an industrial robot, a humanoid robot, etc.

[0319] Thus, the motion detection component of this embodiment can be installed at various positions on the mounted body according to the shape of the mounting part.

[0320] Therefore, it is possible to detect, for example, the movements of movable parts of the installed body (such as the movement of movable parts like elbows and knees at specified angles) and the number of such movements. Furthermore, it is also possible to measure the size of the wrist and waist. In addition, movement detection can be performed through multiple measurements (for example, it is possible to predict and detect human movements by comprehensively measuring the neck, wrist, elbow, shoulder, knee, waist, ankle, and foot).

[0321] (Modified example of the wiring section for testing)

[0322] For the motion detection component of this embodiment, a known sensor other than the detection wiring section 30 (e.g., a pressure sensor, an acceleration sensor, an angular velocity sensor, a magnetic sensor, etc.) can be used. By using other sensors, a higher degree of motion detection can be achieved.

[0323] For example, a pressure sensor can be used to measure the pressure on a telescopic component and determine whether the measured pressure exceeds a predetermined threshold. Additionally, a pressure sensor can be used to detect: pressure when touching an object, contact such as fingers touching each other, or other contact events.

[0324] In addition, time-axis detection sensors such as accelerometers, angular velocity sensors, and magnetic sensors can be used to measure the current shape of the installed object. Time-axis detection sensors can also be combined with the aforementioned telescopic sensors.

[0325] (Server Variation 1)

[0326] The motion detection component 150 of this embodiment can detect finger movements, and therefore can be used in input devices for games, etc. Hereinafter, as a variation, we will describe the application of the motion detection system in a game where it determines whether the hand position is the same as the one displayed on the screen. Furthermore, for the same processing as the server 300 of the above embodiment, the same reference numerals are used and descriptions are omitted.

[0327] like Figure 21 As shown, the modified server 310 is configured to include: a communication unit 311, an action determination unit 312, an image generation unit 313, a display unit 314, a processing unit 315, and a correctness determination unit 316.

[0328] Display unit 314 displays a sample image of a human hand movement transmitted from processing unit 315 on display unit 306. Additionally, display unit 314 displays an image transmitted from processing unit 315 corresponding to the judgment result of error determination unit 316.

[0329] The processing unit 315 performs game processing, namely, determining whether the hand state is the same as the one displayed on the screen. Specifically, first, the processing unit 315 randomly selects a pair from multiple pre-prepared pairs consisting of sample images of human hand movements and correct movements. Next, the processing unit 315 transmits the sample image of the selected pair to the display unit 314. The processing unit 315 then transmits the correct movement of the selected pair to the correctness determination unit 316.

[0330] In addition, when the processing unit 315 receives the judgment result from the correctness judgment unit 316, it transmits the pre-prepared image corresponding to the judgment result to the display unit 314.

[0331] The error determination unit 316 determines whether the action determined by the action determination unit 312 is consistent with the action of the sample image displayed on the display unit 314, i.e., the correct action. Specifically, the error determination unit 316 determines whether the determination result of the action determination unit 312 is consistent with the correct action transmitted from the processing unit 315. That is, when the bending state of a person's fingers is completely consistent for each finger, the error determination unit 316 determines that the action is consistent with the correct action and is therefore correct. If they are inconsistent, the error determination unit 316 determines that the action is incorrect. Furthermore, the error determination unit 316 transmits the determination result to the processing unit 315.

[0332] (The role of the server in Variation Example 1)

[0333] Next, the function of server 310 in variant example 1 will be explained. Figure 22 This is a flowchart illustrating the motion detection processing flow of server 310. CPU 301 reads the motion detection program from ROM 302 or storage device 304 and executes it in RAM 303 to perform the motion detection processing flow. Furthermore, for processes identical to those in server 300, the same reference numerals are used, and descriptions are omitted.

[0334] In step S201, the CPU 301, as a processing unit 315, randomly selects a pair from a plurality of pairs consisting of sample images of human hand movements and correct movements prepared in advance.

[0335] In step S200, the CPU 301, acting as a display unit 314, displays a sample image of the human hand movement selected in step S201 on the display unit 306.

[0336] In step S203, CPU 301, as the correctness determination unit 316, determines whether the action determined by step S102 is consistent with the action of the sample image displayed by step S200, i.e., the correct action.

[0337] In step S204, the CPU 301, acting as a display unit 314, displays an image corresponding to the determination result of step S203 and ends the processing. This process is repeated each time a resistance value is received. Alternatively, a structure can be adopted in which the determination of whether a resistance value has been received is performed at predetermined intervals, and if so, the processing is carried out. Furthermore, a structure can be adopted in which the server 310 displays sample images, etc., on other external terminals.

[0338] Furthermore, although this variation is illustrated using an image, it is also possible to use a moving image instead of an image.

[0339] Thus, for the motion detection system of this modified example, it displays sample images or sample dynamic images of human hand movements, determines whether the action determined by the motion determination unit is consistent with the action in the displayed sample image or sample dynamic image, and displays the determination result, thereby enabling its application to games. Furthermore, by preparing multiple motion detection systems and having them cooperate, it can be applied to games such as rock-paper-scissors, where the motion detection results correspond to those of multiple players.

[0340] (Server Variation Example 2)

[0341] Variation Example 2 illustrates the scenario where action information is pre-associated with and stored, and action determination is performed based on this association. For example... Figure 23 As shown, the server 320 in Modification 2 is configured to include: a communication unit 311, an action determination unit 312, an image generation unit 313, a display unit 314, a processing unit 315, a correctness determination unit 316, a registration unit 317, and a storage unit 318. Furthermore, for processing methods similar to those in the server 300 of the above embodiment and Modification 1, the same reference numerals are used, and descriptions are omitted.

[0342] The registration unit 317 registers the motion information corresponding to each motion in the storage unit 318. For example, for the "motion of making a scissor shape in rock-paper-scissors", among the motion information detected by the motion detection component 150 for each of the five fingers, the registration unit 317 registers the motion information such as "the motion information of the index finger and middle finger exceeds a predetermined threshold and the motion information of the other fingers is below the predetermined threshold" in the storage unit 318.

[0343] The storage unit 318 pre-stores action information corresponding to each action. Specifically, the storage unit 318 registers actions corresponding to the action information.

[0344] The motion determination unit 312 determines what kind of hand movement is being performed based on the motion information. Specifically, when the motion information detected by the motion detection component 150 matches the motion information stored in the storage unit 318, the motion determination unit 312 determines that it is the motion corresponding to the motion information.

[0345] The error determination unit 316 determines whether the action determined by the action determination unit 312 is consistent with the action of the sample image displayed by the display unit 314, i.e., the correct action. Specifically, the error determination unit 316 determines whether the determination result of the action determination unit 312 is consistent with the correct action transmitted from the processing unit 315. That is, the error determination unit 316 determines that the action represented by the determination result of the action determination unit 312 is consistent with the correct action as correct. If they are inconsistent, the error determination unit 316 determines that it is incorrect. Furthermore, the error determination unit 316 transmits the determination result to the processing unit 315.

[0346] As described above, in the motion detection system of this modified example, motion information corresponding to each motion is pre-registered. When the detected motion information is consistent with the registered motion information, it is determined to be the motion corresponding to the motion information, thereby enabling more accurate motion detection.

[0347] (Server variation 3)

[0348] Modification 3 illustrates the case where a time-axis detection sensor, such as an accelerometer, angular velocity sensor, or magnetic sensor, is used. Furthermore, for the same treatments as those in the server 300 of the above-described embodiment, Modification 1, and Modification 2, the same reference numerals are used, and descriptions are omitted.

[0349] In this variation, we will take the case where the motion information is obtained from acceleration information obtained by an acceleration sensor as an example.

[0350] The registration unit 317 stores the action determination model in the storage unit 318. The action determination model takes action information as input and outputs the action corresponding to the action information.

[0351] Specifically, the action determination model is an arbitrary model that can employ a machine learning model that has pre-learned action information and the corresponding actions as teacher data.

[0352] For example, when the action determination model is a neural network, the registration unit 317 pre-learns the action information and the corresponding actions as teacher data, for example, using the inverse error propagation method. In this case, the action information can be represented as a series of vectors corresponding to the time from the initial position to the position after the movement due to the action, and used as input. Furthermore, the registration unit 317 stores the learned action determination model in the storage unit 318.

[0353] The action determination model is stored in the storage unit 318.

[0354] The motion determination unit 312 uses the motion obtained based on the motion information detected by the motion detection component 150 and the motion determination model as the determination result.

[0355] As described above, in the motion detection system of this modified example, motion information detected by the motion detection component 150 and the motion determination model are used to determine motion, thereby enabling more accurate motion detection. The determination model takes the motion information as input and outputs the motion corresponding to the motion information.

[0356] Furthermore, in the above embodiment, the case where the motion determination unit 312 is configured in the server 300 was described as an example, but it is not limited to this. The motion determination unit 312 may also be configured in the motion detection component 150. In this case, the communication unit 206 can send the determination result of the motion determination unit 312 to the server 300. And the communication unit 311 can transmit the received determination result to the image generation unit 313.

[0357] Furthermore, in the above embodiment, the resistance detection unit 204 functions as an action detection unit that detects the action information of the device by utilizing the action detection component 150 installed on the device, but it is not limited to this. Alternatively, it can be structured such that, instead of the resistance detection unit 204, it directly uses an electrical signal as action information and transmits it to the communication unit 206. In this case, the action detection unit uses the action detection component to detect whether the device is moving, i.e., whether there is an electrical signal, as action information. The action detection unit can also be configured as any of the sensors described above.

[0358] Alternatively, it can be configured as a combination of functional structures shown in the embodiments and various modifications.

[0359] Furthermore, the actions and output objects can be freely set, not limited to the examples of the above embodiments. For example, for the action of simply extending the index finger, it can be set as the number 1 and output as a string, or it can be set as the action of turning on the TV and output as a control signal.

[0360] Furthermore, although the example given is a hand, it is not limited to this. It is not limited to gloves or hands; it can be installed on any part of the body that can detect movement. For example, it can be installed on any part that bends, is flexible, or expands and contracts.

[0361] Furthermore, although the example given is a human hand, it is not limited to this. For example, other objects such as animal arms, robot arms, or other working devices can also be used as motion detection objects.

[0362] Furthermore, the entire disclosure of Japanese Patent Application No. 2020-053263 is incorporated herein by reference. Additionally, the inclusion of each document, patent application, and technical standard described herein by reference is to the same extent as its separate and specific description.
