[0001] The present disclosure relates to a motion detection device and an operation system.

[0002] A system for transmitting and processing motion output signals from an agnostic tactile wearable device to a host system that executes, manages, and changes application types is known (JP 2020-504883 A). This system detects one or more hand manipulations of a user via one or more tactile devices, preferably one or more tactile gloves, and provides one or more motion output signals related to the hand manipulations to a processing unit of the one or more tactile devices.

[0003] The above-mentioned Japanese Patent Application Laid-Open No. 2020-504883 does not describe a specific method for detecting manual operations, and there is room for improvement in intuitively converting detected manual operations into operation commands.

[0004] Therefore, an object of the technique of the present disclosure is to provide a motion detection device and an operation system that can intuitively convert motion information of a user's body part into an operation command corresponding to a device to be operated.

[0005] The motion detection device disclosed herein includes a motion detection unit that uses a motion detection member attached to a part of the user's body that can bend and stretch to detect motion information of the part and convert it into an operation command corresponding to the device to be operated.

[0006] The operation system of the present disclosure includes the above-mentioned motion detection device, a command conversion unit that converts the motion information of the part into an operation command corresponding to the device to be operated, and a communication unit that transmits the operation command to the device to be operated.

[0007] According to the present disclosure, it is possible to provide a motion detection device and an operation system that can intuitively convert motion information of a user's body part into an operation command corresponding to a device to be operated.

[0009] <Configuration of an operation system according to an embodiment of the present disclosure> Examples of embodiments of the disclosed technology will be described below with reference to the drawings. Note that the same reference numerals are used to designate identical or equivalent components and parts in each drawing. Also, the dimensional proportions in the drawings are exaggerated for the sake of explanation and may differ from the actual proportions.

[0010] FIG. 1 is a diagram showing the configuration of a manipulation system 1000 according to this embodiment. As shown in FIG. 1, the manipulation system 1000 includes a motion detection device 150, a control device 300, and a manipulation target device 400. The motion detection device 150 and the control device 300, and the control device 300 and the manipulation target device 400 are connected via wireless communication. The manipulation target device 400 is, for example, a drone. <Motion Detection Device> An overview of the motion detection device will be described below. The motion detection device includes a motion detection unit that detects motion information of a part of the user's body that can bend and stretch, using a motion detection member attached to the part, in order to convert the motion information into a manipulation command corresponding to the manipulation target device.

[0011] <Motion Detection Member> An overview of the motion detection member will be described below. In this disclosure, a numerical range using "to" means a numerical range that includes the numerical values ​​before and after "to" as the minimum and maximum values, respectively.

[0012] The motion detection member is a member for detecting the motion of a user of the device to be operated. Examples of the motion detection member include an extension sensor that detects motion by bending and straightening the finger joints (hereinafter also referred to as "extension"), and a time-axis detection sensor such as an acceleration sensor, angular velocity sensor, or magnetic sensor that detects motion by the tilt or position of the hand. In this embodiment, a case where the motion detection member is an extension sensor and an acceleration sensor will be described as an example.

[0013] The motion detection member according to this embodiment is a mounting unit that is attached to a user's body part that can bend and stretch, and includes a mounting unit having an expandable portion that expands and contracts in response to movement of the body part. The motion detection member includes a wiring unit provided on at least a portion of the expandable portion of the mounting unit, the wiring unit having a first wiring unit including a conductive linear member and a second wiring unit including a conductive linear member. The motion detection member includes an electrode unit having a first electrode unit electrically connected to the first wiring unit and a second electrode unit electrically connected to the second wiring unit. The motion detection member includes a wiring electrode unit in which, when the expandable portion of the mounting unit on which the wiring unit is provided expands and contracts in response to movement of the body part, the contact state between the first wiring unit and the second wiring unit changes, thereby changing the resistance value between the first electrode unit and the second electrode unit.

[0014] In the motion detection member according to this embodiment, when the expandable portion expands and contracts (i.e., extends and contracts) due to the movement of the body part, the contact state between the first wiring portion and the second wiring portion changes, causing a change in the resistance value between the first electrode portion and the second electrode portion. By detecting this change in resistance value, the motion of the body part can be detected.

[0015] In the motion detection member according to this embodiment, the wiring electrode portion for detecting motion is configured with a conductive linear body, which provides excellent flexibility and reduces cracks due to expansion and contraction, resulting in high durability.

[0016] In addition, the wiring section made of conductive linear bodies is provided at the stretchable part of the attachment section made of stretchable fabric material. Because it is stretchable, it is less likely to cause discomfort when attached to the body part, and it also has an excellent wearing comfort.

[0017] Japanese Patent Application Laid-Open Publication No. 2016-130940 also describes a glove-type input device, a glove with a strain sensor, and the like. These devices require calibration when the hand is open and closed, but continued use of the glove can cause the sensor position to shift, potentially reducing detection accuracy. On the other hand, the motion detection member according to this embodiment does not require calibration, can be used immediately after wearing, and has a wide tolerance for positional shifts.

[0018] In the present disclosure, "the resistance value between the first electrode portion and the second electrode portion changes" refers to an increase or decrease in the resistance value when the first electrode portion and the second electrode portion are electrically connected. Alternatively, "the resistance value between the first electrode portion and the second electrode portion changes" refers to a change from electrically connected to electrically disconnected or from electrically disconnected to electrically connected between the first electrode portion and the second electrode portion. Note that this change in resistance value does not include a change in resistance value due to damage to the electrode portion, the wiring portion, or the joint between the electrode portion and the wiring portion.

[0019] The phrase "at least a portion of the first wiring portion and the second wiring portion are in contact" also includes a case where there is another wiring portion (e.g., a third wiring portion) other than the first wiring portion and the second wiring portion, in which at least a portion of the first wiring portion and the second wiring portion are in contact with each other via the other wiring portion.

[0020] "The wiring portion is provided in the stretchable portion" means that "the wiring portion is provided on the surface of the stretchable material" or "the wiring portion is provided inside the stretchable fabric material."

[0021] The phrase "the wiring portion is provided on the surface of the stretchable fabric material" means that the wiring portion (i.e., the conductive linear member) is provided on the fabric layer (including the fabric layer that partially forms the front and back surfaces) that constitutes the front and back surfaces of the stretchable fabric material. In other words, the phrase "the wiring portion is provided on the surface of the stretchable fabric material" means that the electrode portion or wiring portion (i.e., the conductive linear member) is provided in a state where at least a part of the conductive linear member that constitutes the wiring portion is exposed from the stretchable fabric material.

[0022] On the other hand, "the wiring portion is provided inside the stretchable fabric material" means that the wiring portion (i.e., the conductive linear body) is provided in the inner layer of the stretchable fabric material, for example, in or between the fabric material layers that form the inner layer of the stretchable fabric material.

[0023] "The attachment part has a stretchable part made of a stretchable fabric material" includes both the first and second embodiments below. The first embodiment is an embodiment in which the position of the attachment part corresponding to the stretchable part is made of a stretchable fabric material, and a wiring part is provided on the stretchable fabric material. The second embodiment is an embodiment in which a separate stretchable fabric material having a wiring part is attached to the surface of the attachment part at the position corresponding to the stretchable part. Note that examples of methods for providing the stretchable part include bonding with an adhesive or attaching by sewing.

[0024] (Configuration of Motion Detection Member) An example of a motion detection member according to this embodiment will be described below with reference to the drawings. The motion detection member according to this embodiment is a fabric material with electrode wiring. In this embodiment, the motion detection member will be described as a glove-shaped member as shown in FIG. 2 . Specifically, the motion detection device 150 has, for example, a glove-shaped wearing part 10 (an example of a wearing part), a wiring electrode part 100, and a communication module 202.

[0025] (Glove-like Wearing Part) The glove-like wearing part 10 is a glove-like wearing part to be worn on the hand of a human body.

[0026] The glove-like wearing part 10 has a wrist part 1 to be worn on the wrist of a human body, finger parts 2 to be worn on the fingers of the human body, and a body part 3 connecting the wrist part 1 and the finger parts 2.

[0027] The wrist 1, the connecting portion of the finger 2 and the torso 3 (the portion corresponding to the metacarpophalangeal joint), and the finger 2 (the portion corresponding to the distal interphalangeal joint and the proximal interphalangeal joint) correspond to an example of an "expandable portion that expands and contracts due to the movement of the portion."

[0028] Furthermore, the part of the finger part 2 facing the back side of the proximal interphalangeal joint corresponds to an example of the "extendable part of the attachment part provided with the wiring part."

[0029] Here, the glove-like wearing part 10 has, for example, five finger parts 2 corresponding to the respective fingers. Specifically, the glove-like wearing part 10 has, as the finger parts 2, for example, a thumb part 2A worn on the thumb, an index finger part 2B worn on the index finger, a middle finger part 2C worn on the middle finger, a ring finger part 2D worn on the ring finger, and a little finger part 2E worn on the little finger.

[0030] However, the configuration of the finger portion 2 is not limited to the above configuration. The glove-like wearing portion 10 may have, as the finger portion 2, two portions, for example, a thumb portion to be worn on the thumb, and finger portions to be worn on the index finger, middle finger, ring finger, and little finger.

[0031] The glove-like wearing part 10 is composed of three (three-layer) fabric layers, for example, a surface fabric layer 10A constituting the surface, a back fabric layer 10B constituting the back surface, and an intermediate fabric layer 10C between the surface fabric layer 10A and the back fabric layer 10B.

[0032] The glove-like wearing part 10 may be configured with, for example, one (single layer), two (two layers), or four (four layers) or more fabric layers other than three fabric layers.

[0033] In addition, a multiple wearing part made of two or more layers of fabric material may be produced, for example, by producing each fabric material layer and then sewing them together, or multiple glove-like wearing parts 10 may be produced all at once using a weaving / knitting machine.

[0034] The glove-like wearing part 10 is made of, for example, a stretchable cloth material. However, it is sufficient that the glove-like wearing part 10 is made of a flexible cloth material and that at least the part of the finger part 2 facing the back side of the proximal interphalangeal joint (an example of a stretchable part of the wearing part where the wiring part is provided) is made of a stretchable cloth material.

[0035] Typical examples of stretchable fabric materials include woven and knitted fabrics. The glove-like application part 10 may be made of nonwoven fabric.

[0036] Examples of woven and knitted fabrics include plain weave, twill weave, satin weave, and known applied weave fabrics; and weft knitting, warp knitting, lace knitting, and known applied knitting fabrics.

[0037] The yarn (linear body) constituting the stretchable fabric material is an insulating yarn. The insulating yarn has a linear resistance of 1.0×10 ６ The insulating yarn has a linear resistance of Ω / cm or more. The linear resistance of the insulating yarn is measured in the same manner as the linear resistance of the conductive linear body described below.

[0038] The stretchable fabric material is preferably a woven or knitted fabric using elastic yarn.

[0039] Examples of elastic yarns include covered yarns (single covered yarns or double covered yarns) in which a non-elastic yarn is wound in a coil shape around the outer periphery of an elastic yarn, core spun yarns in which an elastic yarn and a non-elastic yarn are spin-twisted, air-entangled covered yarns in which a non-elastic yarn is wound around the outer periphery of an elastic yarn using a compressed air nozzle, and twisted yarns in which an elastic yarn and a non-elastic yarn are twisted together.

[0040] Examples of elastic yarns include yarns of fibers exhibiting rubber-like elasticity, such as polyurethane elastic fibers, polyester elastic fibers, and polyamide elastic fibers.

[0041] Examples of inelastic yarns include yarns made of synthetic fibers (polyester fibers, polyamide fibers, acrylic fibers, polypropylene fibers, rayon fibers) and natural fibers (cotton, silk, hemp, wool, and the like).

[0042] (Wiring Electrode Portion) The wiring electrode portion 100 has an electrode portion 20 , a wiring portion 30 , and a wiring portion 50 .

[0043] The electrode unit 20 has a first electrode unit 20A and a second electrode unit 20B, and is electrically connected to the communication module 202.

[0044] The wiring unit 30 has a first detection wiring unit 30A and a second detection wiring unit 30B, and when the part of the finger unit 2 facing the back side of the proximal interphalangeal joint of the finger expands or contracts due to bending of the proximal interphalangeal joint of the finger (an example of a part movement) (hereinafter also referred to as "when the expandable part of the finger unit 2 expands or contracts"), the contact state between the first detection wiring unit 30A and the second detection wiring unit 30B changes in the wiring unit 30 (hereinafter referred to as "detection wiring unit 30").

[0045] The wiring portion 50 has a first connection wiring portion 50A and a second connection wiring portion 50B, and is a connection wiring portion (hereinafter referred to as the "connection wiring portion 50") for electrically connecting the electrode portion 20 and the wiring portion 30.

[0046] The connection wiring section 50 is a wiring section that is provided as needed, and may be configured such that the electrode section 20 and the detection wiring section 30 are directly connected to each other.

[0047] - Electrode Unit - In the electrode unit 20, the first electrode unit 20A and the second electrode unit 20B are each provided, for example, on the back side of the wrist portion 1 of the glove-like wearing unit 10. However, there are no particular limitations on the placement positions of the electrodes, and they may be, for example, on the palm side of the wrist portion 1 of the glove-like wearing unit 10 or the palm side of the torso portion 3 of the glove-like wearing unit 10.

[0048] Depending on the purpose, three or more electrode units 20 may be provided. For example, one electrode unit may be a common electrode, and two or more wiring units 50 may be connected to one electrode unit. An example of this configuration is one in which one of the two wiring units 50 connected to the detection wiring unit 30 arranged on the ring finger 2D and one of the two wiring units 50 connected to the detection wiring unit 30 arranged on the little finger 2E are connected to one electrode unit as a common electrode.

[0049] 3, the electrode portion 20 is provided on the surface fabric layer 10A of the glove-like wearing part 10. In other words, the electrode portion 20 is provided on the surface of the glove-like wearing part 10.

[0050] The electrode unit 20 may be provided on the intermediate fabric layer 10C of the glove-like wearing part 10. In other words, the electrode unit 20 may be provided inside the glove-like wearing part 10. This is because even if the electrode unit 20 is provided inside the glove-like wearing part 10, connection is possible using a pin-shaped electrode or the like.

[0051] -Detection wiring section- The detection wiring section 30 is provided on the part of the finger section 2 facing the back side of the proximal interphalangeal joint of the finger (all parts of the thumb section 2A, index finger section 2B, middle finger section 2C, ring finger section 2D, and little finger section 2E).

[0052] However, the arrangement position of the detection wiring unit 30 is not limited to the above embodiment, and may be the following embodiment depending on the purpose. An embodiment in which the detection wiring unit 30 is provided in a portion of the finger portion 2 facing at least one of the back side of the proximal interphalangeal joint and the back side of the metacarpophalangeal joint. An embodiment in which the detection wiring unit 30 is provided in a portion of the finger portion 2 facing at least one of the palm side of the proximal interphalangeal joint and the palm side of the metacarpophalangeal joint. An embodiment in which some of the multiple detection wiring units 30 are provided in a position facing the portion of the finger portion 2 facing the back side of the finger, and the remaining portions are provided in a position facing the portion of the finger portion 2 facing the palm side of the finger. In this embodiment, for example, the detection wiring unit 30 is provided in a position facing the portion of the thumb portion 2A facing the palm side of the thumb. In this embodiment, the detection wiring unit 30 is further provided at a position facing the index finger portion 2B, the middle finger portion 2C, the ring finger portion 2D, and the little finger portion 2E that face the back of the index finger portion, the middle finger portion 2C, the ring finger portion 2D, and the little finger portion 2E.

[0053] In the detection wiring section 30, the first detection wiring section 30A is electrically connected to the first electrode section 20A. Furthermore, the second detection wiring section 30B is electrically connected to the second electrode section 20B.

[0054] The first detection wiring portion 30A and the second detection wiring portion 30B are separate members, and are provided so that at least a portion of them is in contact with each other when the expandable portion of the finger portion 2 is in a state before extension.

[0055] However, when a part of the detection wiring unit 30 is provided at a position facing the part of the thumb portion 2A facing the palm side of the finger (for example, when the detection wiring unit 30 is provided at a position facing the part of the thumb portion 2A facing the palm side of the thumb, and the detection wiring unit 30 is provided at a position facing the parts of the index finger portion 2B, middle finger portion 2C, ring finger portion 2D, and little finger portion 2E facing the back side of the index finger portion, middle finger portion, ring finger portion, and little finger portion), in the detection wiring unit 30 at a position facing the part of the thumb portion 2A facing the palm side of the thumb, the first detection wiring unit 30A and the second detection wiring unit 30B are separate and are provided apart from each other in a state before the extensible portion of the finger portion 2 is extended.

[0056] In addition, an embodiment in which the first detection wiring portion 30A and the second detection wiring portion 30B are separate and spaced apart before the extension portion of the finger portion 2 is extended will be described in the first modified example.

[0057] The first detection wiring portion 30A extends, for example, along the longitudinal direction of the finger portion 2. The first detection wiring portion 30A has a wavy portion 32A in which the conductive linear body 40A2 is provided in a wavy shape.

[0058] The second detection wiring portion 30B extends, for example, along the longitudinal direction of the finger portion 2. The second detection wiring portion 30B also has a wavy portion 32B in which the conductive linear body 40B2 is provided in a wavy shape.

[0059] Before the expandable portion of the finger 2 is extended, the wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B are in point contact or line contact.

[0060] Note that both the first detection wiring unit 30A and the second detection wiring unit 30B may have only straight portions where the conductive linear members 40A2 and 40B2 are arranged in a straight line, without having a wavy portion where the conductive linear members 40A2 and 40B2 are arranged in a wavy line. Also, both the first detection wiring unit 30A and the second detection wiring unit 30B may have bent portions where the conductive linear members 40A2 and 40B2 are bent.

[0061] The detection wiring unit 30 is provided inside the glove-like wearing part 10. Specifically, for example, as shown in Fig. 3, the detection wiring unit 30 is provided in a middle fabric layer 10C, which is an inner fabric layer (including a fabric layer that is a partial inner layer) of the glove-like wearing part 10 made up of three fabric layers, so that the detection wiring unit 30 can be provided inside the glove-like wearing part 10. Alternatively, for example, the detection wiring unit 30 may be provided between the fabric layers of the glove-like wearing part 10 made up of two fabric layers.

[0062] The detection wiring unit 30 may be provided on the surface of the glove-like wearing part 10. For example, the detection wiring unit 30 may be provided on the front fabric layer 10A or the back fabric layer 10B of the glove-like wearing part 10 which is made up of three fabric layers. However, from the viewpoint of insulating the glove-like wearing part 10 from the outside, it is preferable to provide the detection wiring unit 30 inside the glove-like wearing part 10.

[0063] -Connection wiring portion 50- In the connection wiring portion 50, the first connection wiring portion 50A electrically connects the first electrode portion 20A and the first detection wiring portion 30A. The second connection wiring portion 50B electrically connects the second electrode portion 20B and the second detection wiring portion 30B.

[0064] The connecting wiring portion 50 is provided on the trunk portion 3 of the glove-like wearing portion 10 facing the back of the hand.

[0065] However, the arrangement position of the connection wiring section 50 is not limited to the above embodiment, and is set in accordance with the arrangement positions of the electrode section 20 and the detection wiring section 30.

[0066] The connecting wiring 50 is provided inside the glove-like wearing part 10. Specifically, for example, the connecting wiring 50 is provided in the middle fabric layer 10C, which is the inner fabric layer (including a fabric layer that is a partial inner layer) of the glove-like wearing part 10 made up of three fabric layers, so that the connecting wiring 50 can be provided inside the glove-like wearing part 10. Alternatively, for example, the connecting wiring 50 may be provided between the fabric layers of the glove-like wearing part 10 made up of two fabric layers.

[0067] The connecting wiring 50 may be provided on the surface of the glove-like wearing part 10. For example, the connecting wiring 50 may be provided on the front fabric layer 10A or the back fabric layer 10B of the glove-like wearing part 10 which is made up of three fabric layers. However, from the viewpoint of insulating the glove-like wearing part 10 from the outside, it is preferable to provide the connecting wiring 50 inside the glove-like wearing part 10.

[0068] -Conductive Linear Body- The electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 each include a conductive linear body 40. In other words, the regions in which the conductive linear body 40 is arranged are defined as the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50.

[0069] Specifically, for example, the first electrode portion 20A includes a conductive linear member 40A1.

[0070] The first connection wiring portion 50A includes a conductive linear body 40A3 that is an extension of the conductive linear body 40A1 of the first electrode portion 20A.

[0071] The first detection wiring portion 30A includes a conductive linear member 40A2 that is an extension of the conductive linear member 40A3 of the first connection wiring portion 50A.

[0072] In other words, the first electrode unit 20A and the first detection wiring unit 30A are configured from at least one identical conductive linear body 40 .

[0073] Moreover, for example, the second electrode portion 20B includes a conductive linear member 40B1.

[0074] The second connection wiring portion 50B includes a conductive linear body 40B3 that is an extension of the conductive linear body 40B1 of the second electrode portion 20B.

[0075] The second detection wiring portion 30B includes a conductive linear member 40B2 that is an extension of the conductive linear member 40B3 of the second connection wiring portion 50B.

[0076] In other words, the second electrode portion 20B and the second detection wiring portion 30B are configured from at least one identical conductive linear member 40 .

[0077] The first electrode portion 20A and the first detection wiring portion 30A, and the second electrode portion 20B and the second detection wiring portion 30B are each composed of the same single conductive linear body 40, thereby suppressing poor connection between the electrode portion 20 and the detection wiring portion 30.

[0078] In addition, the same single conductive linear body 40 also includes a linear body in which the ends of the conductive linear body 40 are connected by tying or twisting, etc., without using any connecting material (solder, conductive paste, etc.) or connecting member (crimping, connector, etc.) other than the linear body.

[0079] However, the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 may each include a plurality of conductive linear members 40. Furthermore, the first electrode unit 20A, the first detection wiring unit 30A, and the first connection wiring unit 50A, and the second electrode unit 20B, the second detection wiring unit 30B, and the second connection wiring unit 50B do not each have to be configured with the same single conductive linear member 40.

[0080] For example, the first electrode unit 20A, the first detection wiring unit 30A, and the first connection wiring unit 50A, and the second electrode unit 20B, the second detection wiring unit 30B, and the second connection wiring unit 50B may each have the ends of their respective conductive linear bodies 40 connected to each other by a connecting material (solder, conductive paste, etc.) or a connecting member (crimping, connector, etc.) other than the linear bodies.

[0081] 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 part of the conductive linear member 40 is restrained by the thread of the glove-like wearing part 10 .

[0082] Such a configuration is preferable from the viewpoint that the conductive linear body 40, which functions as a conductive material, can also be used as a means for fixing the electrode portion 20, the detection wiring portion 30, and the connection wiring portion 50 to the glove-like wearing portion 10.

[0083] The conductive linear body 40 restrained by the glove-like wearing part 10 may be the same conductive linear body 40 included in the electrode part 20, the detection wiring part 30, and the connection wiring part 50. Alternatively, the conductive linear body 40 restrained by the glove-like wearing part 10 may be a different conductive linear body 40 included in only one of the electrode part 20, the detection wiring part 30, and the connection wiring part 50.

[0084] In at least one of the electrode section 20 , the detection wiring section 30 and the connection wiring section 50 , the conductive linear member 40 does not have to be restrained by the thread of the glove-like wearing part 10 .

[0085] For example, when at least one of the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 is fixed to the glove-like wearing part 10 with an adhesive, the following aspect occurs: In this aspect, when at least one of the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 is sewn to the glove-like wearing part 10 with insulating thread, the following aspect occurs: In other words, even if the conductive linear body 40 is not restrained by the thread of the glove-like wearing part 10, at least one of the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 can be fixed to the glove-like wearing part 10.

[0086] For example, a rectangular region is formed by repeatedly bending or curving the conductive linear member 40 through 180°. This rectangular region is formed by constraining a part of the conductive linear member 40 to the threads of the surface fabric layer 10A of the glove-like application part 10. This rectangular region then becomes the planar electrode part 20.

[0087] The region in which the conductive linear body 40 is arranged in a spiral shape may be the electrode portion 20. Also, the conductive linear body 40 may be arranged in a bent or curved shape to have any surface shape (polygonal, circular, etc.) as the electrode portion 20.

[0088] On the other hand, a region is formed in which the conductive linear body 40 extends from the electrode portion 20 in a straight, wavy, bent, or combination thereof. This region is formed by constraining a part of the conductive linear body 40 to the thread of the intermediate fabric material layer 10C of the glove-like wearing portion 10. This region then becomes the detection wiring portion 30 and the connection wiring portion 50.

[0089] Specifically, when the glove-like wearing part 10 is a woven fabric, it is preferable to weave the conductive linear members 40 into the weave of a fabric woven with warp and weft threads to form the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50, as shown in Fig. 7, from the following viewpoints: The first viewpoint is that when forming the glove-like wearing part 10 by weaving, the glove-like wearing part 10, the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 can be formed simultaneously. The second viewpoint is that the glove-like wearing part 10, the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 can be formed in a uniform manner.

[0090] When the glove-like wearing part 10 is a knitted fabric, it is preferable to form the electrode part 20, the detection wiring part 30, and the connection wiring part 50 by knitting the conductive linear body 40 in the above-described shape into a knitted structure of the knitted fabric into which loop-shaped yarns are knitted, as shown in Fig. 7, from the following viewpoints. The first viewpoint is that when forming the glove-like wearing part 10 by knitting, the glove-like wearing part 10, the electrode part 20, the detection wiring part 30, and the connection wiring part 50 can be formed simultaneously. The second viewpoint is that the glove-like wearing part 10, the electrode part 20, the detection wiring part 30, and the connection wiring part 50 can be formed in a uniform manner.

[0091] When the conductive linear body 40 is woven into the knitted structure of the knitted fabric, for example, a paired knitting, a plating knitting, an inlay knitting, etc. can be used. Fig. 7 shows an example in which the conductive linear body 40 is woven using an inlay knitting.

[0092] 8, it is preferable to embroider the conductive linear body 40 in the above-described shape onto the glove-like wearing part 10 to form the electrode part 20, the detection wiring part 30, and the connection wiring part 50 from the following viewpoint: When forming the electrode part 20, the detection wiring part 30, and the connection wiring part 50, it is possible to simultaneously fix the electrode part 20, the detection wiring part 30, and the connection wiring part 50 to the glove-like wearing part 10.

[0093] The embroidery method may employ well-known stitches such as a running stitch, a coating stitch, a back stitch, a chain stitch, an outline stitch, etc. Fig. 8 shows an example in which the conductive linear body 40 is embroidered using a chain stitch.

[0094] Furthermore, it is preferable from the following viewpoint to sew and fix the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 to the glove-like wearing unit 10 with the conductive linear body 40. This viewpoint is preferable from the viewpoint that the conductive linear body 40 constituting the electrode unit 20, the conductive linear body 40 fixing the detection wiring unit 30, and the conductive linear body 40 fixing the connection wiring unit 50 can be made to be a common body.

[0095] For example, the following embodiment can be given as an example of the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 being fixed by sewing with the conductive linear members 40. In this embodiment, the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 are continuously formed from a woven fabric into which the conductive linear members 40 are woven or a knitted fabric into which the conductive linear members 40 are knitted. Furthermore, the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 are sewn to the glove-like wear part 10 with the conductive linear members 40.

[0096] In Fig. 6, 12 denotes warp yarns constituting the glove-like wearing part 10 (woven fabric), and 14 denotes weft yarns constituting the glove-like wearing part 10 (woven fabric). In Fig. 7, 16 denotes yarns constituting the glove-like wearing part 10 (woven fabric).

[0097] In addition, when elastic yarn is used as the yarn constituting the glove-like wearing part 10, it is preferable to weave or knit the conductive linear body 40 into the glove-like wearing part 10 while forming a woven or knitted fabric with the elastic yarn in a stretched state.

[0098] (Conductive Linear Body) The conductive linear bodies constituting the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 are not particularly limited as long as they are conductive, and examples thereof include linear bodies including metal wires and linear bodies including conductive threads. The conductive linear body 40 may be a linear body including metal wires and conductive threads (e.g., a linear body in which metal wires and conductive threads are twisted together). In this embodiment, the conductive linear bodies included in the electrode unit 20, the detection wiring unit 30, and the connection wiring unit 50 are made of the same material.

[0099] Both the linear body including a metal wire and the linear body including a conductive thread have high electrical conductivity, so when used as the conductive linear body 40, it becomes easy to reduce the resistance of the electrode section 20, the detection wiring section 30, and the connection wiring section 50.

[0100] Examples of metal wires include wires containing metals such as copper, aluminum, tungsten, iron, molybdenum, nickel, titanium, silver, and gold, or alloys containing two or more metals (for example, steels such as stainless steel and carbon steel, brass, phosphor bronze, zirconium-copper alloys, beryllium copper, iron-nickel, nichrome, nickel-titanium, Kanthal, Hastelloy, and rhenium-tungsten). The metal wire may be plated with tin, zinc, silver, nickel, chromium, nickel-chromium alloys, solder, or the like, or may be surface-coated with a carbon material or polymer, as described below.

[0101] The metal wire may be coated with a carbon material, which inhibits metal corrosion.

[0102] Examples of carbon materials that can be used to coat the metal wire include amorphous carbon such as carbon black, activated carbon, hard carbon, soft carbon, mesoporous carbon, and carbon fiber; graphite; fullerene; graphene; and carbon nanotubes.

[0103] On the other hand, the linear body including the conductive thread may be a linear body consisting of a single conductive thread, or may be a linear body formed by twisting multiple conductive threads. It may also be a linear body formed by twisting a conductive thread and an insulating thread. The linear body including the conductive thread has the advantage of being more flexible than a linear body including a metal wire, and is less likely to break when woven, knitted, or embroidered into the glove-like wearing part 10, or when sewn to the glove-like wearing part 10.

[0104] Examples of conductive yarns include yarns containing conductive fibers (metal fibers, carbon fibers, ion-conductive polymer fibers, etc.), yarns containing conductive microparticles (carbon nanoparticles, etc.) (hereinafter referred to as carbon nanotube yarns), yarns whose surfaces are plated or vapor-deposited with metals (copper, silver, nickel, etc.), and yarns impregnated with metal oxides.

[0105] A particularly suitable example of a linear body containing a conductive thread is a linear body containing a carbon nanotube thread (hereinafter also referred to as a "carbon nanotube linear body").

[0106] Carbon nanotube linear bodies can be obtained, for example, by drawing carbon nanotubes into a sheet from the end of a carbon nanotube forest (a growth structure in which multiple carbon nanotubes are grown on a substrate so as to be aligned perpendicular to the substrate; sometimes referred to as an "array"), bundling the drawn carbon nanotube sheets, and then twisting the bundles of carbon nanotubes. In this production method, if no twist is applied during twisting, ribbon-shaped carbon nanotube linear bodies are obtained, while if twist is applied, thread-shaped carbon nanotube linear bodies are obtained. Ribbon-shaped carbon nanotube linear bodies are linear bodies that do not have a structure in which a collection of multiple carbon nanotubes is twisted. Alternatively, carbon nanotube linear bodies can be obtained by spinning a carbon nanotube dispersion. Carbon nanotube linear bodies can be produced by spinning, for example, using the method disclosed in U.S. Patent Publication US 2013 / 0251619 (Japanese Patent Laid-Open Publication No. 2011-253140). From the viewpoint of obtaining uniformity in the diameter of the carbon nanotube linear bodies, it is desirable to use thread-like carbon nanotube linear bodies, and from the viewpoint of obtaining high-purity carbon nanotube linear bodies, it is preferable to obtain thread-like carbon nanotube linear bodies by twisting a carbon nanotube sheet. The carbon nanotube linear bodies may be linear bodies formed by twisting two or more carbon nanotube linear bodies together.

[0107] The carbon nanotube linear body may be a linear body (hereinafter also referred to as a "composite linear body") that includes carbon nanotubes and a conductive material other than carbon nanotubes, such as a metal, a conductive polymer, graphene, etc. The composite linear body tends to improve the conductivity of the linear body while maintaining the above-described characteristics of the carbon nanotube linear body.

[0108] Examples of composite linear bodies include linear bodies containing carbon nanotubes and metals, such as: (1) a composite linear body in which a metal or a metal alloy is supported on the surface of a forest, sheet, or bundle of carbon nanotubes, or twisted linear body, by vapor deposition, ion plating, sputtering, wet plating, or the like, in a process of obtaining a carbon nanotube linear body by drawing carbon nanotubes from the end of a carbon nanotube forest into a sheet, bundling the drawn carbon nanotube sheets, and then twisting the carbon nanotube bundles; (2) a composite linear body in which bundles of carbon nanotubes are twisted together with linear bodies of a metal or a metal alloy, or a composite linear body; and (3) a composite linear body in which linear bodies of a metal or a metal alloy, or a composite linear body, are twisted together with carbon nanotube linear bodies or composite linear bodies. Note that in the composite linear body of (2), a metal may be supported on the carbon nanotubes when twisting the bundles of carbon nanotubes, as in the composite linear body of (1). Furthermore, the composite linear body of (3) is a composite linear body in which two linear bodies are braided together, but as long as it contains at least one linear body of a simple metal or a metal alloy, or a composite linear body, it may be a composite linear body in which three or more carbon nanotube linear bodies, or linear bodies of a simple metal or a metal alloy, or a composite linear body are braided together.

[0109] Examples of the metal for the composite linear body include simple metals such as gold, silver, copper, iron, aluminum, nickel, chromium, tin, and zinc, and alloys containing at least one of these simple metals (such as copper-nickel-phosphorus alloys and copper-iron-phosphorus-zinc alloys).

[0110] Among these conductive linear bodies 40, conductive linear bodies containing carbon nanotube yarns (particularly, conductive linear bodies containing only carbon nanotube yarns, or conductive linear bodies containing carbon nanotube yarns and non-metallic conductive materials) are preferred.

[0111] For example, threads whose surfaces are plated or vapor-deposited with metal (copper, silver, nickel, etc.) or threads impregnated with metal oxides are prone to cracking in the metal or metal oxide when stretched repeatedly, resulting in low durability. In contrast, carbon nanotube linear bodies are highly resistant to bending, and the resistance value of the wiring portion is less likely to change even when the stretchable portion of the finger portion 2 is stretched repeatedly. Carbon nanotube linear bodies also have the advantage of being highly corrosion-resistant.

[0112] Here, the line resistance of the conductive linear body 40 is 5.0×10 －３ Ω / cm ~ 1.0×10 ３ Ω / cm is preferred, and 1.0×10 －２ Ω / cm ~ 5.0×10 ２ Ω / cm is more preferred.

[0113] The linear resistance of the conductive linear body 40 is measured as follows: First, silver paste is applied to both ends of the conductive linear body 40, and the resistance of the portion between the silver pastes is measured to determine the resistance value (unit: Ω) of the conductive linear body 40. The obtained resistance value is then divided by the distance (cm) between the silver pastes to calculate the linear resistance of the conductive linear body 40.

[0114] (Acceleration Sensor) The motion detection device 150 further includes an acceleration sensor 152 as a motion detection member. As shown in FIG. 2 above, the acceleration sensor 152 is provided at a portion that corresponds to the user's wrist. Therefore, this motion detection device 150 can detect the direction of the user's hand. However, this is not the only possible configuration, and the acceleration sensor 152 may be provided at a portion that corresponds to each of the user's fingertips. This configuration makes it possible to detect the movement of each of the user's fingertips.

[0115] (Communication Module) The communication module 202 is provided, for example, on the back side of the wrist portion 1 of the glove-like wearing part 10. However, the location of the communication module 202 is not particularly limited, and it may be, for example, on the palm side of the wrist portion 1 of the glove-like wearing part 10 or the palm side of the torso of the glove-like wearing part 10.

[0116] The communication module is electrically connected to the electrode section 20 via a connection terminal (not shown).

[0117] The communication module 202 is detachably attached to the glove-like wearing part 10 by means of, for example, a hook-and-loop fastener. By removing the communication module 202 from the glove-like wearing part 10, the motion detection member can be selected without waterproofing the communication module.

[0118] The communication module 202 includes a resistance detection unit 204 and a communication unit 206 (FIG. 5). The communication module 202 also includes a power supply unit (not shown).

[0119] The resistance detection unit 204 is a sensor for detecting a resistance value. Functionally, the resistance detection unit 204 detects the resistance value between the first electrode unit 20A and the second electrode unit 20B. The resistance detection unit 204 then passes the detected resistance value to the communication unit 206. In this way, the resistance detection unit 204 detects information about the movement of the part using a movement detection member attached to the part.

[0120] The communication unit 206 is a communication device for wireless communication with the control device 300. When communicating directly with the control device 300, the communication unit 206 complies with standards such as IEEE802.15.1 and IEEE802.15.4. When communicating with the control device 300 via a wireless base station or a wireless router, the communication unit 206 complies with standards such as Wi-Fi (registered trademark) and LTE, and communicates directly with the wireless base station or wireless router. The communication unit 206 may also be configured to transmit data on detected resistance values ​​to the control device 300 via a wired connection. Functionally, the communication unit 206 transmits data on the resistance values ​​detected by the resistance detection unit 204 and data on acceleration detected by the acceleration sensor 152 to the control device 300.

[0121] (Function of Motion Detecting Member) In the motion detecting member according to this embodiment, at least a portion (in this embodiment, the wavy portions 32A, 32B) of the first detection wiring portion 30A and the second detection wiring portion 30B are in contact with each other before the stretchable portion of the finger portion 2 of the glove-like wearing portion 10 is stretched (see FIG. 4A ). Specifically, at least a portion of the conductive linear body 40A2 constituting the first detection wiring portion 30A is in contact with the conductive linear body 40B2 constituting the second detection wiring portion 30B.

[0122] On the other hand, when the stretchable portion of the finger portion 2 of the glove-like wearing unit 10 is stretched by bending the fingers (bending the proximal interphalangeal joint), the first detection wiring unit 30A and the second detection wiring unit 30B, which had been in contact with each other, separate when a certain stretch rate is reached (see FIG. 4B ). Specifically, the conductive linear body 40A2 constituting the first detection wiring unit 30A and the conductive linear body 40B2 constituting the second detection wiring unit 30B separate from each other.

[0123] More specifically, when the extensible portion of the finger 2 is stretched, 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 become longer and the amplitude becomes smaller, thereby separating the first detection wiring portion 30A and the second detection wiring portion 30B.

[0124] When the expandable portion of the finger 2 is stretched by this action, the resistance between the first electrode 20A and the second electrode 20B changes. That is, the resistance increases. Specifically, the state between the first electrode 20A and the second electrode 20B changes from conductive to non-conductive.

[0125] Then, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B due to the extension, the movement of the fingers (bending of the proximal interphalangeal joints of the fingers) can be detected.

[0126] On the other hand, when the bending of the finger (bending of the proximal interphalangeal joint) is released and the extension of the extensible portion of the finger portion 2 is released (i.e., contracted), at a certain extension rate, at least a portion of the first detection wiring portion 30A and the second detection wiring portion 30B, which had been separated, come into contact (see FIG. 4A ). In other words, the resistance value decreases. Specifically, the first electrode portion 20A and the second electrode portion 20B go from being non-conductive to being conductive.

[0127] In this way, by detecting the change in resistance between the first electrode portion 20A and the second electrode portion 20B due to expansion and contraction, the movement of the fingers (releasing of the bending of the proximal interphalangeal joint of the finger) can be detected.

[0128] Here, for an extensible portion of the finger 2 (i.e., the extensible portion of the attachment portion provided with the detection wiring unit) having the maximum extensibility (=approximately 80%), the extensible portion of the finger 2 was stretched to an extensibility of 70% and then contracted, and this operation was repeated five times at an extension / contraction speed of 1 mm / s. 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 extension rate and the measurement time, is shown in Fig. 9. Furthermore, an example of the relationship between the resistance value between the first electrode 20A and the second electrode 20B and the extension rate during the first extension / contraction, based on the measurement results shown in Fig. 9, is shown in Fig. 10.

[0129] 9 and 10 , when the expandable portion of finger 2 (i.e., the expandable portion of the attachment portion on which the detection wiring portion is provided) expands or contracts, the resistance value between first electrode 20A and second electrode 20B changes at a certain expansion rate. Specifically, the resistance between first electrode 20A and second electrode 20B changes from conduction to non-conduction and then from non-conduction to conduction.

[0130] As shown in FIGS. 9 and 10 , the motion detection device 150 can detect the motion of the fingers of the hand (bending and releasing of the proximal interphalangeal joints of the fingers) by detecting a change in resistance value between the first electrode unit 20A and the second electrode unit 20B due to the expansion and contraction of the expansion and contraction portion of the finger unit 2 (i.e., the expansion and contraction portion of the attachment part on which the detection wiring unit is provided).

[0131] The measurement results of the resistance change shown in Figures 9 and 10 show that, within an average extension rate range of approximately 43.7% ± 5%, the resistance increases when the sample is extended and decreases when the sample is contracted.

[0132] <Control Device> Next, we will explain the control device 300. The control device 300 converts the resistance value data and acceleration data detected by the motion detection device 150 into an operation command corresponding to the operation target device 400, and transmits the operation command to the operation target device 400.

[0133] (Configuration of Control Device) Fig. 11 is a block diagram showing the hardware configuration of the control device 300 according to this embodiment. As shown in Fig. 11, the control device 300 includes a CPU (Central Processing Unit) 301, a ROM (Read Only Memory) 302, a RAM (Random Access Memory) 303, a storage 304, an input unit 305, a display unit 306, and an antenna 307. Each component is connected to each other via a bus 309 so as to be able to communicate with each other. As the control device 300, a computer dedicated to the operation target device 400 may be used, or various information processing devices such as a smartphone or a tablet device may be used.

[0134] The CPU 301 is a central processing unit that executes various programs and controls each part. That is, the CPU 301 reads a program from the ROM 302 or the storage 304 and executes the program using the RAM 303 as a work area. The CPU 301 controls each of the above components and performs various arithmetic processing in accordance with the program stored in the ROM 302 or the storage 304. In this embodiment, a command conversion program is stored in the ROM 302 or the storage 304.

[0135] The ROM 302 stores various programs and various data. The RAM 303 temporarily stores programs or data as a working area. The storage 304 is configured by a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various programs including an operating system and various data.

[0136] The input unit 305 is used to input various information.

[0137] The display unit 306 is, for example, a liquid crystal display, and displays various information. The display unit 306 may be a touch panel type and function as the input unit 305.

[0138] The antenna 307 is an antenna for wireless communication with the motion detection device 150 and the operation target device 400, and complies with standards such as IEEE802.15.1 and IEEE802.15.4 when communicating directly with the operation target device 400. Note that the antenna 307 can use standards such as Wi-Fi (registered trademark) and LTE when communicating with the operation target device 400 via a wireless base station or a wireless router.

[0139] Next, the functional configuration of the control device 300 will be described. Fig. 12 is a block diagram showing an example of the functional configuration of the control device 300. As shown in Fig. 12, the control device 300 has, as its functional configuration, a communication unit 311, an operation determination unit 312, and a command conversion unit 313. Each functional configuration is realized when the CPU 301 reads out a command conversion program stored in the ROM 302 or storage 304, expands it in the RAM 303, and executes it.

[0140] The communication unit 311 receives the resistance value data and acceleration data from the motion detection device 150. The communication unit 311 then passes the received resistance value data and acceleration data to the motion determination unit 312.

[0141] The movement determination unit 312 determines the movement of the user based on the resistance value data and acceleration data received from the communication unit 206 .

[0142] Specifically, the movement determination unit 312 determines that there is a bending movement of the fingers of the hand when the difference between a predetermined resistance value and the resistance value detected by the resistance detection unit 204 is equal to or greater than a predetermined threshold value.

[0143] Here, the movement determination unit 312 determines whether or not a bending movement has occurred for each finger, and which finger the movement determination unit 312 is for may be configured to receive in advance resistance value data and information indicating which finger the movement determination unit 312 is for from the movement detection device 150. The movement determination unit 312 determines whether or not a bending movement has occurred for each finger based on the resistance values ​​detected by the resistance detection units 204, which are provided for each finger.

[0144] Furthermore, the movement determination unit 312 determines the direction of the user's hand based on the acceleration data detected by the acceleration sensor 152 .

[0145] The command conversion unit 313 converts the combination of the determination results of whether or not each finger has been bent and the determination results of the direction of the user's hand into an operation command corresponding to the device to be operated 400, and transmits the operation command to the device to be operated 400 via the antenna 307.

[0146] For example, the command conversion unit 313 converts the command into an operation command that indicates the flight direction relative to the reference direction, depending on the direction of the hand relative to the reference direction. The command conversion unit 313 converts the command into an operation command that slows the flight speed as the number of fingers with bending motions increases. Furthermore, when all fingers have bending motions, the command conversion unit 313 converts the command into an operation command to hover.

[0147] (Operation of Control Device) The operation of the control device 300 will now be described. Fig. 13 is a flowchart showing the flow of a command conversion processing routine by the control device 300. The CPU 301 reads out a command conversion program from the ROM 302 or storage 304, loads it into the RAM 303, and executes it, thereby performing processing by the control device 300.

[0148] In step S101 , the CPU 301 functions as the communication unit 311 to receive resistance value data and acceleration data from the motion detection device 150 .

[0149] In step S102, the CPU 301 functions as the movement determination unit 312 and determines whether or not there is a bending movement in each finger of the hand based on the resistance value data received from the communication unit 206.

[0150] In step S103 , the CPU 301 functions as the motion determination unit 312 to determine the direction of the user's hand based on the acceleration data received from the communication unit 206 .

[0151] In step S104, the CPU 301, functioning as the command conversion unit 313, determines whether or not there is an operation command corresponding to the combination of the bending motion of each finger of the hand determined in step S102 and the hand orientation determined in step S103. If there is no operation command corresponding to the combination of the bending motion of each finger of the hand determined in step S102 and the hand orientation determined in step S103, the command conversion process ends. On the other hand, if there is an operation command corresponding to the combination of the bending motion of each finger of the hand determined in step S102 and the hand orientation determined in step S103, the process proceeds to step S105. In step S105, the CPU 301, functioning as the command conversion unit 313, transmits the operation command to the operation target device 400 via the antenna 307, and ends the command conversion process.

[0152] The routine is repeated each time resistance value data and acceleration data are received. Alternatively, the routine may be configured to determine at a predetermined interval whether resistance value data and acceleration data have been received, and to perform the processing if they have been received.

[0153] As described above, the operation system of the present disclosure includes a motion detection unit that uses a motion detection member attached to a user's bending and straightening body part to detect motion information of the body part and convert it into an operation command corresponding to the device to be operated. This makes it possible to provide an operation system that can intuitively convert motion information of the user's body part into an operation command corresponding to the device to be operated.

[0154] The motion detection member is a mounting part that is attached to a body part and includes a stretchable part that stretches and contracts in response to the movement of the body part, and a wiring electrode part that detects stretching information indicating the stretching when the stretchable part of the mounting part stretches and contracts. This provides an excellent wearing comfort, so the wearer does not feel uncomfortable when there is movement, and the motion detection member has little effect on the movement. This allows for more accurate detection of movement.

[0155] Furthermore, the control device can detect any range of motion by determining whether or not a part is moving based on the resistance value received from the communication unit. By providing multiple thresholds, it is also possible to detect multi-stage motion.

[0156] Furthermore, instead of operating a conventional physical controller, the user's hand movements themselves become the controller, allowing the user to intuitively operate the device to be operated.

[0157] Furthermore, by using the stretch sensor, it is possible to perform motion detection using a motion detection member that is highly durable and comfortable to wear, which means it is possible to provide an operation system that is comfortable to wear and can accurately detect hand motions.

[0158] (Modification of Wiring Electrode Section) In the motion detection device 150 according to this embodiment, the wiring electrode section is not limited to the configuration of the wiring electrode section 100 shown in FIG. 4, and may be modified or improved.

[0159] Hereinafter, modified examples of the wiring electrode portion in the motion detecting member according to this embodiment will be described.

[0160] In the following description, if the wiring electrode portion is the same as the member described in the above embodiment, the same reference numeral will be used in the drawings and the description thereof will be omitted or simplified.

[0161] In the following description, the connection wiring portion will be omitted.

[0162] -First Modification- The wiring electrode portion may be, for example, the wiring electrode portion 101 shown in FIG. 14A.

[0163] 14A , in the wiring electrode portion 101, the first detection wiring portion 30A and the second detection wiring portion 30B are spaced apart from each other before the extension portion of the attachment portion on which the detection wiring portion 30 is provided (hereinafter simply referred to as the "extendable portion of the attachment portion") is extended. The wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B are arranged substantially parallel to each other and opposed to each other, with a space between them.

[0164] When the expandable portion of the attachment part is expanded by the movement of the part, at least a portion of the first detection wiring part 30A and the second detection wiring part 30B, which were separated, come into contact when a certain expansion rate is reached (see FIG. 14B ). Specifically, at least a portion of the conductive linear body 40A2 constituting the first detection wiring part 30A and the conductive linear body 40B2 constituting the second detection wiring part 30B come into contact.

[0165] More specifically, when the elastic portion of the attachment part is stretched, the wavy portion 32A of the first detection wiring part 30A and the wavy portion 32B of the second detection wiring part 30B approach and come into contact, with their period becoming longer and their amplitude becoming smaller.

[0166] When the expandable portion of the attachment part is expanded by this action, the resistance value between the first electrode part 20A and the second electrode part 20B changes. In other words, the resistance value decreases. Specifically, the first electrode part 20A and the second electrode part 20B go from being non-conductive to being conductive.

[0167] Then, by detecting a change in resistance between the first electrode portion 20A and the second electrode portion 20B that accompanies extension, the movement of the part can be detected.

[0168] On the other hand, when the extension of the expandable portion of the attachment part is released (i.e., contracted) by the movement of the part, the first detection wiring part 30A and the second detection wiring part 30B, which had been in contact, separate when a certain extension rate is reached (see FIG. 14A ). In other words, the resistance value increases. Specifically, the first electrode part 20A and the second electrode part 20B go from being electrically connected to being electrically disconnected.

[0169] 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 part can be detected.

[0170] --Second Modification-- The wiring electrode portion may be, for example, the wiring electrode portion 102 shown in FIG. 15A.

[0171] Specifically, as shown in FIG. 15A, the wiring electrode portion 102 has, as the wavy portion 32A of the first detection wiring portion 30A, a first wavy portion 32A1 and a second wavy portion 32A2 that has a different contact length with the wavy portion 32B of the second detection wiring portion 30B than the first wavy portion 32A1.

[0172] The wiring electrode portion 102 has, as the wavy portion 32A of the first detection wiring portion 30A, a first wavy portion 32A1 and a second wavy portion 32A2 that has a different period and / or amplitude from the first wavy portion 32A1.

[0173] In this example, the second wavy portion 32A2 has a shorter contact length with the wavy portion 32B of the second detection wiring portion 30B than the first wavy portion 32A1, and the second wavy portion 32A2 has a shorter period and smaller amplitude than the first wavy portion 32A1.

[0174] When the extension portion of the attachment portion on which the detection wiring portion 30 is provided (hereinafter simply referred to as the "extendable portion of the attachment portion") is extended by the movement of the attachment portion, the first detection wiring portion 30A and the second detection wiring portion 30B, which had been in contact, are partially separated when a certain extension rate is reached (see FIG. 15B). Specifically, the second wavy portion 32A2 of the first detection wiring portion 30A is separated from the wavy portion 32B of the second detection wiring portion 30B.

[0175] When the wire is further stretched and reaches a certain stretch rate, the second wavy portion 32A2 of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B separate from each other (see FIG. 15C).

[0176] In other words, the second wavy portion 32A2 of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B separate first, and the first wavy portion 32A1 of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B separate later.

[0177] When the expandable portion of the attachment part is stretched by this action, the resistance value between the first electrode unit 20A and the second electrode unit 20B changes stepwise. That is, the resistance value increases stepwise by the amount of increase in contact resistance caused by partial separation between the first detection wiring unit 30A and the second detection wiring unit 30B. Specifically, when the first electrode unit 20A and the second electrode unit 20B are in a conductive state, the resistance value increases by a certain amount, and then the connection changes to non-conduction.

[0178] Then, by detecting the gradual change in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompanies extension, the gradual movement of the body part can be detected.

[0179] On the other hand, when the extension of the elastic part of the attachment part is released (i.e., contracts) due to the movement of the part, the first wavy part 32A1 of the first detection wiring part 30A and the wavy part 32B of the second detection wiring part 30B, which were separated, come into contact when a certain extension rate is reached (see Figure 15B).

[0180] Furthermore, when the wire contracts and reaches a certain elongation rate, the second wavy portion 32A2 of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B, which had been separated from each other, come into contact with each other (see FIG. 15A ). That is, the resistance value decreases stepwise.

[0181] Specifically, after the first electrode portion 20A and the second electrode portion 20B are changed from non-conductive to conductive, the resistance value decreases in the conductive state.

[0182] In this way, by detecting the gradual change in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompanies contraction, it is possible to detect the gradual movement of the part.

[0183] In the second modification, the contact portion between the wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B may have a plurality of regions with different contact lengths in accordance with the intended gradual change in the resistance value between the first electrode portion 20A and the second electrode portion 20B. At least one of the first detection wiring portion 30A and the second detection wiring portion 30B may have a plurality of wavy portions with different periods and / or amplitudes.

[0184] Note that a gradual change in resistance value (i.e., a gradual increase or decrease) means that the resistance value changes as the telescopic portion of the attachment part stretches, and after that change in resistance value has stopped, the resistance value changes again.

[0185] -Third Modification- The wiring electrode unit may be, for example, the wiring electrode unit 103 shown in Fig. 16A. Specifically, as shown in Fig. 16A, the wiring electrode unit 103 further includes a third electrode unit 20C as the electrode unit 20, and a third detection wiring unit 30C as the detection wiring unit 30.

[0186] The third electrode unit 20C includes a conductive linear member 40C1. The third detection wiring unit 30C includes a conductive linear member 40C2 that is an extension of the conductive linear member 40C1 of the third electrode unit 20C. In other words, the third electrode unit 20C and the third detection wiring unit 30C are configured from at least one identical conductive linear member 40.

[0187] The third detection wiring portion 30C is electrically connected to the third electrode portion 20C.

[0188] The third detection wiring portion 30C is separate from the first detection wiring portion 30A and the second detection wiring portion 30B, and is interposed between the first detection wiring portion 30A and the second detection wiring portion 30B and is in contact with at least a portion of the first detection wiring portion 30A and the second detection wiring portion 30B before the extension of the expansion / contraction portion of the mounting portion on which the detection wiring portion 30 is provided (hereinafter simply referred to as the "expandable portion of the mounting portion").

[0189] The third detection wiring portion 30C has, for example, a wavy portion 32C in which the conductive linear member 40C2 is provided in a wavy shape.

[0190] Furthermore, before the extension portion of the attachment portion is extended, the wavy portion 32C of the third detection wiring portion 30C is in point contact or line contact with the wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B.

[0191] However, the contact length between the wavy portion 32C of the third detection wiring portion 30C and the wavy portion 32A of the first detection wiring portion 30A is different from the contact length between the wavy portion 32C of the third detection wiring portion 30C and the wavy portion 32B of the second detection wiring portion 30B. The periods and / or amplitudes of the wavy portion 32C of the third detection wiring portion 30C, the wavy portion 32A of the first detection wiring portion 30A, and the wavy portion 32B of the second detection wiring portion 30B are different.

[0192] In this example, the contact length between the wavy portion 32C of the third detection wiring portion 30C and the wavy portion 32A of the first detection wiring portion 30A is shorter than the contact length between the wavy portion 32C of the third detection wiring portion 30C and the wavy portion 32B of the second detection wiring portion 30B. The wavy portion 32C of the third detection wiring portion 30C has a smaller amplitude than the wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B.

[0193] When the expandable portion of the attachment part expands, the first and third detection wiring parts 30A and 30C, which had been in contact with each other, separate when the expansion rate reaches a certain level (see FIG. 14B ). Specifically, the wavy portion 32A of the first detection wiring part 30A separates from the wavy portion 32C of the third detection wiring part 30C.

[0194] As the wiring portion 30B is further stretched, the second and third detection wiring portions 30B and 30C, which had been in contact with each other, separate when a certain stretch rate is reached (see FIG. 16C ). Specifically, the wavy portion 32B of the second detection wiring portion 30B separates from the wavy portion 32C of the third detection wiring portion 30C.

[0195] That is, the first detection wiring portion 30A and the third detection wiring portion 30C separate first, and the second detection wiring portion 30B and the third detection wiring portion 30C separate last.

[0196] When the expandable portion of the attachment part is expanded by this action, the resistance value between the first electrode part 20A and the third electrode part 20C changes. In other words, the resistance value increases. Specifically, the first electrode part 20A and the third electrode part 20C go from being electrically connected to being electrically disconnected.

[0197] Further extension changes the resistance between the second electrode portion 20B and the third electrode portion 20C. That is, the resistance increases. Specifically, the state between the second electrode portion 20B and the third electrode portion 20C changes from conductive to non-conductive.

[0198] The movement of the part can be detected 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 occurs as the part is stretched.

[0199] On the other hand, when the extension of the expandable portion of the attachment part is released (i.e., contracts) due to the movement of the part, the second and third detection wiring parts 30B and 30C, which had been separated, come into contact at a certain extension rate (see FIG. 16B ). Specifically, the wavy portion 32B of the second detection wiring part 30B comes into contact with the wavy portion 32C of the third detection wiring part 30C.

[0200] As the detection wiring portion 30A further contracts, the first and third detection wiring portions 30A and 30C, which were previously separated, come into contact with each other at a certain elongation rate (see FIG. 16A ). Specifically, the wavy portion 32A of the first detection wiring portion 30A comes into contact with the wavy portion 32C of the third detection wiring portion 30C.

[0201] That is, the second detection wiring portion 30B and the third detection wiring portion 30C come into contact first, and the first detection wiring portion 30A and the third detection wiring portion 30C come into contact last.

[0202] In this way, by detecting the change in resistance value between the first electrode portion 20A and the third electrode portion 20C, and the change in resistance value between the second electrode portion 20B and the third electrode portion 20C that accompanies contraction, the gradual movement of the part can be detected.

[0203] In addition, the third modified example may be such that the second detection wiring portion 30B and the third detection wiring portion 30C separate first, and the first detection wiring portion 30A and the third detection wiring portion 30C separate later.

[0204] --Fourth Modification-- The wiring electrode portion may be, for example, the wiring electrode portion 104 shown in FIG. 17A.

[0205] 17A , in the wiring electrode portion 104, the first detection wiring portion 30A and the second detection wiring portion 30B are spaced apart from each other before the extension portion of the attachment portion on which the detection wiring portion 30 is provided (hereinafter simply referred to as the "extendable portion of the attachment portion") is extended. The wavy portion 32A of the first detection wiring portion 30A and the wavy portion 32B of the second detection wiring portion 30B are opposed to each other and spaced apart from each other at an angle (for example, an angle of 3° to 30° formed by the extension directions of the respective wavy portions).

[0206] When the expandable portion of the attachment part is expanded by the movement of the part, at least a portion of the first detection wiring part 30A and the second detection wiring part 30B, which were separated, come into contact when a certain expansion rate is reached (see FIG. 17B ). Specifically, at least a portion of the conductive linear body 40A2 constituting the first detection wiring part 30A and the conductive linear body 40B2 constituting the second detection wiring part 30B come into contact.

[0207] More specifically, when the elastic portion of the attachment part is stretched, the period of the wavy portion 32A of the first detection wiring part 30A and the wavy portion 32B of the second detection wiring part 30B become longer and the amplitude becomes smaller, and the tip side (the tip side not connected to the second electrode part 20B) of the wavy portion 32B of the second detection wiring part 30B approaches and comes into contact with the wavy portion 32A of the first detection wiring part 30A.

[0208] Further extension increases the contact area between the first detection wiring portion 30A and the second detection wiring portion 30B (see FIG. 17C ). Specifically, the contact area between the conductive linear body 40A2 constituting the first detection wiring portion 30A and the conductive linear body 40B2 constituting the second detection wiring portion 30B increases.

[0209] More specifically, when the elastic portion of the attachment part is stretched, the wavy portion 32A of the first detection wiring part 30A and the wavy portion 32B of the second detection wiring part 30B come closer together, with the period becoming longer and the amplitude becoming smaller, and the contact area increasing.

[0210] This action causes the resistance value between the first electrode unit 20A and the second electrode unit 20B to change stepwise when the expandable portion of the attachment unit is extended. That is, when the first detection wiring unit 30A and the second detection wiring unit 30B first come into contact, the first electrode unit 20A and the second electrode unit 20B go from a non-conductive state to a conductive state. Next, as the contact area between the first detection wiring unit 30A and the second detection wiring unit 30B increases, the contact resistance decreases, and the resistance value between the first electrode unit 20A and the second electrode unit 20B decreases stepwise.

[0211] Then, by detecting the gradual change in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompanies extension, the gradual movement of the body part can be detected.

[0212] On the other hand, when the extension of the expandable portion of the attachment part is released (i.e., contracted) by the movement of the part, the contact area between the first detection wiring part 30A and the second detection wiring part 30B decreases ( FIG. 17B ). Furthermore, when the extension rate is reached, the first wavy portion 32A1 of the first detection wiring part 30A and the wavy portion 32B of the second detection wiring part 30B, which had been in contact, separate (see FIG. 17A ). In other words, the resistance value increases stepwise.

[0213] Specifically, the resistance value decreases when the first electrode portion 20A and the second electrode portion 20B are in a conductive state, and then the first electrode portion 20A and the second electrode portion 20B are in a non-conductive state.

[0214] In this way, stepwise movement of a part can also be detected by detecting stepwise changes in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompany contraction.

[0215] -Fifth Modification- The wiring electrode unit may be, for example, the wiring electrode unit 105 shown in FIG. 18A . Specifically, as shown in FIG. 18A , the wiring electrode unit 105 has a first detection wiring unit 30A and a second detection wiring unit 30B integrally provided as the detection wiring unit 30. Specifically, for example, the first detection wiring unit 30A and the second detection wiring unit 30B as the detection wiring unit 30 are configured from a single conductive linear body 40 that is an extension of the conductive linear bodies 40 that configure the first electrode unit 20A and the second electrode unit 20B. In other words, in the wiring electrode unit 105, the first electrode unit 20A and the second electrode unit 20B are electrically connected by a single detection wiring unit 30. Note that the detection wiring unit 30 may be configured from a plurality of conductive linear bodies 40.

[0216] In the middle of the detection wiring section 30, before the extension portion of the mounting section on which the detection wiring section 30 is provided (hereinafter simply referred to as the "extension portion of the mounting section") is extended, the detection wiring section 30 is repeatedly bent or curved by 180°, and has a contact section 34 where at least a portion of the detection wiring section 30 between the bent or curved sections comes into contact with each other.

[0217] In other words, in the middle of the detection wiring section 30, before the extension portion of the attachment section is extended, the conductive linear bodies 40 are repeatedly bent or curved through 180°, and there is a contact section 34 where at least a portion of the conductive linear bodies 40 between the bent or curved sections are in contact with each other.

[0218] When the expandable portion of the attachment part expands along the extension direction of the detection wiring parts 30, the detection wiring parts 30 that are in contact between the bent or curved parts at the contact parts 34 of the detection wiring parts 30 move apart (see FIG. 18B ), thereby lengthening the conduction path between the first electrode part 20A and the second electrode part 20B.

[0219] When the expandable portion of the attachment part is expanded by this action, the resistance value between the first electrode portion 20A and the second electrode portion 20B changes. That is, the resistance value increases by the amount corresponding to the increase in the conductive path.

[0220] Then, by detecting a change in resistance between the first electrode portion 20A and the second electrode portion 20B that accompanies extension, the movement of the part can be detected.

[0221] On the other hand, when the extension of the expandable portion of the attachment part is released (i.e., contracted) due to the movement of the part, the detection wiring part 30 repeatedly bends or curves 180° in the middle of the detection wiring part 30, and a contact part 34 is formed where at least a part of the detection wiring part 30 between the bent or curved parts comes into contact with each other (see Figure 18A).

[0222] When the expandable portion of the attachment part contracts 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 by the amount corresponding to the reduction in the conductive path.

[0223] Furthermore, the movement of the part can also be detected by detecting a change in the resistance value between the first electrode portion 20A and the second electrode portion 20B that accompanies contraction.

[0224] In addition, in the fifth variant, the amount of change in resistance value between the first electrode portion 20A and the second electrode portion 20B can be controlled by increasing or decreasing the contact area between the detection wiring portions 30 at the contact portions of the detection wiring portions 30.

[0225] -Sixth Modification- The wiring electrode portion may be, for example, the wiring electrode portion 106 shown in Fig. 19. In other words, an extension portion of the glove-like wearing part on which the detection wiring portion is provided may be arranged on the surface of the glove-like wearing part at the corresponding position.

[0226] Specifically, as shown in FIG. 19 , the wiring electrode unit 106 (the electrode unit 20 , the detection wiring unit 30 and the connection wiring unit 50 ) is provided on a stretchable fabric material 60 .

[0227] The stretchable fabric material 60 is composed of three fabric layers: a surface fabric layer 60A that forms the surface, a back fabric layer 60B that forms the back surface, and an intermediate fabric layer 10C that is located between the surface fabric layer 60A and the back fabric layer 60B. The structure of the stretchable fabric material 60 is the same as the fabric that forms the glove-like wearing part 10.

[0228] The electrode unit 20 is provided, for example, on the surface fabric layer 60A of the stretchable fabric material 60. The detection wiring unit 30 is provided, for example, on the intermediate fabric layer 10C of the stretchable fabric material 60. The connection wiring unit 50 is provided, for example, on the intermediate fabric layer 10C of the stretchable fabric material 60.

[0229] The stretchable fabric material 60 provided with the wiring electrode portion 106 is then placed on the surface of the glove-like wearing part 10 at the corresponding position by well-known fixing means such as sewing or adhesive.

[0230] In the sixth variant, the stretchable cloth material 60 provided with the wiring electrode portion 106 is placed on the surface of the glove-like wearing part 10 at the corresponding position, so that the glove-like wearing part 10 can be made of well-known materials such as resin, paper, leather, etc. in addition to cloth material.

[0231] -Seventh Modification- The wiring electrode portion may be, for example, the wiring electrode portion 107 shown in Fig. 20. In other words, an extension portion of the glove-like wearing part on which the detection wiring portion is provided may be arranged on the surface of the glove-like wearing part at the corresponding position.

[0232] Specifically, as shown in FIG. 20, a button electrode (such as a snap button) is arranged as the electrode portion 20 on the surface of the glove-like wearing portion 10 at a corresponding position by a known fixing means such as sewing or adhesive.

[0233] The detection wiring unit 30 is provided on a stretchable fabric material 70. The stretchable fabric material 70 is made up of three fabric layers: a surface fabric material layer 70A that forms the surface, a back fabric material layer 70B that forms the back surface, and an intermediate fabric material layer 70C that is located between the surface fabric material layer 70A and the back fabric material layer 70B. The structure of the stretchable fabric material 70 is the same as the fabric material that forms the glove-like wearing part 10.

[0234] The stretchable fabric material 70 on which the detection wiring section 30 is provided is provided on the surface of the glove-like wearing part 10 .

[0235] The connecting wiring section 50 is provided on the surface of the glove-like wearing part 10, connecting the electrode section 20 and the detection wiring section 30. The connecting wiring section 50 is covered with a well-known insulating sheet 72 made of a cloth material, a resin material, or the like.

[0236] In the seventh variant, the wiring electrode portion 107 is also arranged on the surface of the corresponding position of the glove-like wearing part 10, so the glove-like wearing part 10 can be made of well-known materials such as resin, paper, leather, etc. in addition to cloth material.

[0237] (Characteristics) In order to detect the movement of the part, the stretchable portion of the attachment portion provided with the detection wiring unit 30 (hereinafter simply referred to as the "stretchable portion of the attachment portion") preferably has an elongation rate range in which the resistance value between the first electrode unit 20A and the second electrode unit 20B changes by more than two times or less than one-half (preferably more than ten times or less than one-tenth, and more preferably more than one hundred times or less than one-hundredth) within a range of ±5% change in elongation rate. In other words, it is preferable that the resistance value between the first electrode unit 20A and the second electrode unit 20B changes by more than two times or less than one-half per 10% change in elongation rate during the elongation process of the stretchable portion of the attachment portion.

[0238] Specifically, when the maximum elongation rate of the elastic part of the attachment part is X (where 10≦X), and the elongation rate at a certain point when the elastic part of the attachment part is elongated is Y (where 5≦Y≦(X−5)), it is preferable that the elastic part has a region in which the maximum resistance value changes to 2 times or more or 1 / 2 or less (preferably 10 times or more or 1 / 10, more preferably 100 times or more or 1 / 100) of the minimum resistance value within the range of Y−5% to Y+5%.

[0239] As an example, the stretchable portion of the attachment portion has a region where the resistance between the first electrode portion 20A and the second electrode portion 20B changes by more than two times as the extension rate changes by 10% during the extension process. The stretchable portion of the attachment portion further has a region where the resistance between the first electrode portion 20A and the second electrode portion 20B changes by one-tenth or less as the extension rate changes by 10%. This change in resistance is calculated as the ratio of the resistance at the target extension rate to the resistance at the point when the extension rate has changed by 10% from that point.

[0240] In addition, there may be two or more ranges of elongation rates in which the resistance value between the first electrode portion 20A and the second electrode portion 20B changes by more than two times or by less than half within a range of ±5% change in elongation rate.

[0241] Furthermore, the ratio of the elongation rate to the maximum elongation rate (elongation rate / maximum elongation rate), at which the resistance value between the first electrode portion 20A and the second electrode portion 20B changes by more than two times or by half or less within a range of ±5% change in elongation rate, is preferably in the range of 0.1 to 0.9 (preferably 0.2 to 0.8). When this ratio is in the above range, the movement of the part can be detected efficiently while preventing malfunction.

[0242] Furthermore, there may be a range in which the resistance value changes significantly in response to changes in the elongation rate, and a range in which the resistance value changes very little in response to changes in the elongation rate.

[0243] The change in resistance value between the first electrode portion 20A and the second electrode portion 20B accompanying the expansion and contraction of the expansion and contraction portion of the attachment portion is measured as follows.

[0244] While measuring the resistance between the first electrode 20A and the second electrode 20B, the expandable portion of the attachment part is expanded to its maximum extension at a speed of 1 mm / s, and then contracted at the same speed until it returns to its original state. The resistance value is plotted every second to measure the change in resistance. The direction of expansion of the expandable portion of the attachment part is the direction in which the change in resistance due to expansion and contraction is to be detected.

[0245] Here, the stretch rate of the stretchable portion of the attachment part is calculated by the formula: ((length in the stretching direction when stretched) - (length in the stretching direction before stretching)) / (length in the stretching direction before stretching) x 100.

[0246] On the other hand, the maximum elongation rate of the stretchable portion of the attachment part is calculated by the formula: ((length in the stretching direction at maximum stretch) - (length in the stretching direction before stretching)) / (length in the stretching direction before stretching) x 100.

[0247] The maximum extension of the elastic part of the attachment part is the length at which the elastic part of the attachment part cannot be extended any further when extended with an appropriate tension. In other words, the maximum extension of the elastic part of the attachment part is the length at which the elastic part of the attachment part is extended with a tension at which extension stops.

[0248] (Shape of the Motion Detection Member (its Wearing Portion) and the like) In the above embodiment, the shape of the wearing portion of the motion detection device 150 is described as a glove-like shape, but this is not limited to this. Depending on the purpose of motion detection, the shape of the wearing portion may be various shapes such as a cylinder, a sheet, or a belt.

[0249] The cylindrical attachment part may be in the shape of a supporter, wristband, or the like. The sheet-like attachment part may be in the shape of a supporter, wristband, or the like, which has fasteners on both ends and is wrapped around the area. In the case of a sheet-like attachment part, the sheet-like attachment part may be attached to the area with an adhesive. The belt-like attachment part may be in the shape of suspenders, or the like. The shape of the attachment part is selected depending on the area where it is to be attached.

[0250] Here, examples of the places where the device is attached include, but are not limited to, movable parts of the human body (neck, wrist, elbow, shoulder, knee, waist, ankle, foot, etc.).

[0251] In this way, the motion detecting member according to this embodiment can be attached to various parts of the body depending on the shape of the attachment part.

[0252] This makes it possible to detect, for example, the movement of a moving part of a body part (such as the movement of a moving part such as an elbow or knee at a predetermined angle) and the number of times it moves. Furthermore, it is also possible to measure the size of the arm or waist. It is also possible to detect movement through multiple measurements (for example, it is possible to predict and detect a person's movement by measuring the neck, wrist, elbow, shoulder, knee, waist, ankle, foot, etc. in combination).

[0253] (Modifications of Sensors) The motion detection member according to this embodiment may be provided with a well-known sensor other than an acceleration sensor (e.g., an angular velocity sensor, a magnetic sensor, etc.). Furthermore, the motion detection member may be provided with a contact detection sensor. For example, a contact detection sensor provided on the palm side can detect contact between fingers, between a finger and an object, between a finger and a knee, or between a finger and an elbow.

[0254] (Variations of Device to be Operated) The device to be operated according to this embodiment may be a well-known device other than a drone (for example, a headset-type terminal such as VR (Virtual Reality) goggles capable of displaying three-dimensional images).

[0255] In the above embodiment, the case where the motion determination unit 312 is configured in the control device 300 has been described as an example, but the present invention is not limited to this. The motion determination unit 312 may be configured to be included in the motion detection device 150. In this case, the communication unit 206 may be configured to transmit the determination result by the motion determination unit 312 to the control device 300. Then, the communication unit 311 may be configured to pass the received determination result to the command conversion 313.

[0256] The motion determination unit 312 and the command conversion unit 313 may be configured to be included in the motion detection device 150. In this case, the communication unit 206 may be configured to transmit the conversion result by the command conversion unit 313 to the operation target device 400.

[0257] Furthermore, in the above embodiment, the resistance detection unit 204 functions as a motion detection unit that detects motion information of a part using the motion detection device 150 attached to the part, but this is not limited to this. Instead of the resistance detection unit 204, the motion detection unit may be configured to use the electrical signal as motion information and pass it directly to the communication unit 206. In this case, the motion detection unit detects the presence or absence of motion of the part using a motion detection member, i.e., the presence or absence of an electrical signal, as motion information. The motion detection unit may be configured as each of the above sensors.

[0258] Furthermore, the functional configurations shown in the embodiment and each modification can be combined.

[0259] Furthermore, although the example has been described in which the bendable and stretchable part is the hand, this is not a limitation. Gloves can be worn on any part that can be bent and stretched, not just the hand. For example, they can be worn on any part that bends, folds, expands, or contracts.

[0260] Although the example has been described in which the body part is a human hand, the present invention is not limited to this. For example, other objects such as animals and machine tools such as robot arms can also be used as motion detection targets.

[0261] Furthermore, in the above application examples, the glove-shaped motion detection device 150 and motion detection member 160 capable of detecting relatively complex motions are mainly used as the motion detection unit, but the present invention is not limited to this. For example, when a relatively simple-shaped object such as a supporter or wristband is used and a relatively simple motion detection member having only one sensor is used as the motion detection unit, only on / off detection is possible.
