2 is a view showing a combined state and a disassembled state of the finger motion detection sensor and the sensor movement unit according to the present invention.
3 is a view illustrating a battery unit according to the present invention.
FIG. 4 is a cross-sectional view illustrating a back part and a wrist part of a motion recognition glove for an augmented reality according to the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings, and the same reference numerals are given to the background art and the constituent elements of the constitution which have already been described.

The description of the motion-sensing glove for an augmented reality of the present invention described below is a preferred embodiment of the present invention and is not limited to the embodiment, but may be implemented in various forms.

In addition, the shape, size, and the like of each constitution described below are representative examples and are not fixed, and can be variously changed if the same effect can be realized.

The overall shape of the motion recognition glove 1 for an augmented reality according to the present invention is substantially similar to that of a general glove and includes a finger portion 10, a wrist portion 30, and a back portion 20 The finger unit 10 is divided into a thumb unit 11, a detection unit 12, a stop unit 13, a weak unit 14, and a grip unit 15.

1 and 4, a motion recognition glove 1 for augmented reality according to an exemplary embodiment of the present invention includes a finger motion detection sensor 100, a hand motion detection sensor 200, a sensor movement unit 300 A main enclosure 500 and a battery unit 400 and is divided into an upper enclosure 40 and a lower enclosure 50 and an inner skin 60 located between the upper enclosure 40 and the lower enclosure 50 do.

The general glove is made up of only the outer skin forming a space into which a human hand can be inserted. However, the augmented reality motion recognition glove 1 according to the present invention has the upper skin 40, the lower skin 50 and the inner skin 60 And an insertion space 70 and an installation space 80 are formed by an inner skin 60 positioned between the upper and lower outer shells 40 and 50. [

A human hand is inserted into the insertion space 70 formed between the inner skin 60 and the lower outer skin 50. An installation space 80 formed between the inner skin 60 and the upper skin 40 is provided with a finger A motion detection sensor 100, a hand motion motion detection sensor 200, a wiring (not shown), a sensor movement unit 300, a main circuit unit 500, and a battery unit 400 are provided.

The finger motion detection sensor 100 is provided in the thumb 11, the detection unit 12, the stop 13, the weak portion 14 and the finger 15 of each finger 10 of the glove 1 , And detects the finger movement of the person wearing the glove 1.

The human hand has two joints on the thumb and three joints on the other finger, and each node of the finger moves in the vertical direction (z-axis direction) or the lateral direction (y-axis direction) around the joint.

Therefore, in order to precisely detect and analyze the movement of each finger, it is preferable that the finger motion sensor 100 is positioned at a position corresponding to the position between the joints of the person and the joint. In the case of the thumb and small finger, A separate finger motion sensor 100 is provided on the lower side of the thumb 11 and the finger 15 so as to detect the movement of the finger more precisely .

In the embodiment of the present invention, an IMU sensor (Inertial Measurement Unit Sensor) is used to detect the movement of the finger, and a bending sensor (Flex Sensor) may be applied.

However, the bending sensor senses the movement by measuring the resistance value which changes according to the degree of bending of the sensor. In the case of the bending movement toward the lower side, the change in the resistance value is insignificant The detection effect is reduced.

In addition, since the bending sensor must be provided to have a predetermined length, it is positioned on both sides of the joint of the finger, and the sensing error is increased because the size of the hand and the position of the joint are slightly different for each person.

On the other hand, the IMU sensor senses the gravity to determine the height, and senses the dynamic acceleration such as shaking, rotation, directional motion, and inertia, so it can detect movement in the direction of 360 °.

In addition, the tilt, motion, and vibration of the object can be grasped, and the function of the digital compass can be realized by measuring the magnetic field of the earth in various directions, and it can be manufactured in a very small size.

Therefore, it is desirable to apply the IMU sensor as an optimal sensor for more precisely sensing the movement of the finger, and such an IMU sensor includes the sensor unit 110 and the circuit unit 120. [

The hand motion detecting sensor 200 is provided in the handgrip 20 of the glove 1 to detect movement of the hand of the person wearing the glove 1. There is a joint between the back of the hand and the wrist. The wrist moves around the joint in the vertical direction (z-axis direction) or the left-right direction (y-axis direction) and rotates in the 360 ° direction.

That is, the movement of the back of the hand is much wider than that of the finger, and the hand-operated motion detection sensor 200 must accurately detect the movement of the back of the hand.

The motion recognition glove 1 for augmented reality according to the present invention includes the finger 10, the handgrip 20 and the wrist 30, but the position of the human's hand changes as the person moves . Accordingly, in order to be applied to the augmented reality, the position of the glove 1 itself must be detectable, and in the embodiment of the present invention, such a function is implemented in the handgrip motion sensor 200. [

Accordingly, the hand-operated motion detection sensor 200 is preferably an IMU sensor capable of implementing all of the functions described above.

The size of the hand and the position of the joint are different for each person who wears gloves. Since gloves are manufactured and sold at certain sizes in the factory, if the joints are not positioned even if the gloves are purchased according to the size of the hand, The accuracy of the sensor 100 is reduced.

2, it is preferable to include a sensor movement unit 300 that moves the position of the finger motion detection sensor 100, and the sensor movement unit 300 according to the present invention includes an upper enclosure 40 ) And the endothelium (60).

The sensor moving unit 300 includes a moving shaft 310, a body 320, a stopper 340, and an elastic member 350. The moving shaft 310 protrudes from the sensor moving unit 300,

The moving shaft 310 is provided between the upper shell 40 and the inner shell 60 at a position where the body 320 described later moves according to the operation of the wearer. The plurality of moving shafts 310 may be spaced apart from each other by a predetermined distance, and each moving shaft 310 may be formed long by one for each finger 10.

A stopping protrusion 311 protruding from the surface of the moving shaft 310 at a predetermined interval in contact with a stopper 340 described later is formed on the surface of the moving shaft 310. The moving shaft 310 may have various shapes such as a circular shape and a square shape.

The body 320 is coupled with the finger motion sensor 100 and moves on the moving shaft 310. The body 320 is formed with a component insertion area 330 and protrudes outside the upper shell 40.

That is, it is possible to form a predetermined region of the upper enclosure 40 in an open state so that the body 320 can be easily manipulated and moved, and if necessary, the finger motion sensor 100 may be coated with a special purpose coating such as a waterproof coating .

A stopper 340 is provided in the component insertion area 330 formed on the body 320 so as to make contact with the stopping protrusion 311 in accordance with an external force applied by the wearer. So as to prevent the stopper 340 from coming off.

An elastic member 350 such as a spring is coupled to the stopper 340 and the stopper 340 is brought into close contact with the moving shaft 310 through an elastic action of compressing / expanding according to an external force applied to the stopper 340, When the external force is applied to the stopper 340, the body 320 can move, and when the external force is removed, the body 320 can not move.

The main circuit unit 500 is connected to the above-described finger motion sensor 100 and the hand motion motion sensor 200 via wires (not shown) to transmit power supplied from a battery unit 400 described later, And analyzes the motion and transmits the analyzed result to an external device such as a computer and is provided in the handgrip 20 or the wrist 30.

The main circuit unit 500 includes a main PCB 510 having a Bluetooth module, a CPU and the like for transmitting and analyzing data from the finger motion sensor 100 and the hand motion motion sensor 200, And all of the motions sensed through the finger motion sensor 100 and the hand motion motion sensor 200 are transmitted to an external computer via Bluetooth, USB, or the like.

Since the main circuit unit 500 is connected to each sensor by wiring (not shown) and has a component such as a CPU, the size of the main circuit unit 500 is larger than that of the finger motion detection sensor 100.

Therefore, it is preferable that the hand unit 20 or the wrist unit 30 is provided so as not to inconvenience the movement of the wearer. In an embodiment of the present invention, as shown in FIG. 3, The hand-operated motion detection sensor 200 described above is disposed in the main circuit unit 500. [

The battery unit 400 supplies power to the above-described finger motion sensor 100, the hand motion sensor 200, and the main circuit unit 500. In order to prevent the wearer from feeling inconvenience due to the weight of the battery, (30) of the wrist (1).

The battery unit 400 is provided with a charging terminal 410 for charging and a power unit 420 for turning on and off the power, and it is also possible to install a residential battery, which is generally sold, as well as a rechargeable battery.

4, the motion-sensing glove 1 for augmented reality according to the present invention is constructed by using a zipper, a magnet, an adhesive member, or the like on the outer surface between the back 20 and the wrist 30, And a space securing member 600 that can be opened /

The present invention is applied to only the upper shell 40 so that a part of the upper shell 40 can be opened and closed. However, the present invention is also applicable to the lower shell 50, ) May be formed in a detachable shape.

The space securing member 600 includes the finger motion detecting sensor 100, the hand motion detecting sensor 200, the sensor moving unit 300, the main circuit unit 500, the battery unit 400, and the wiring (not shown) And facilitates maintenance in the event of a failure.

In other words, if there is no space securing member 600, all the above-described structures must be installed before sewing the upper jacket 40 and the lower jacket 50 of the glove 1, There is a problem in that the user needs to remove all of the sewn upper cover 40 and repair it, and sew the upper cover 40 again when the repair is completed.

Therefore, after the upper enclosure 40 is opened using the space securing member 600, the glove 1 is turned upside down so that the inside of the upper enclosure 40 is exposed to the outside, When the operation is completed, the space-saving member 600 is turned upside down, restored to the original state, and thus the manufacturing process and maintenance are facilitated.

The motion recognition glove 1 for augmented reality according to the present invention can be applied to various fields, but it is preferable to open the end portion of the finger 10 when it is applied to a training using a finger directly, such as a machine assembly.

That is, when the end of the finger 10 is covered with the upper shell 40 and the lower shell 50, not only the feeling touching the hand is insufficient, but also when the glove 1 does not fit accurately in the hand, It is impossible to grasp the minute parts correctly and the correct motion detection and analysis can not be performed.

Therefore, in order to maximize the training effect, it is desirable to move the fingers accurately by opening the end portion of the finger portion 10, and to sense and analyze the movement accordingly.
