Meanwhile, the strap unit 200 may have a circular strap shape in which the size of an inner space surrounding the wearer's head is adjusted by the length adjusting unit 400 . Here, the circular strap may correspond to the main strap 210 .

The gesture sensor unit 300 is provided on the side of the augmented reality glasses device 10 to receive an input signal by a gesture of a nearby hand, and transmits a gesture in which the hand moves in a first direction within a sensing distance as a first input signal. , each gesture of moving the hand in the second direction may be received as the second input signal.

Here, the gesture sensor unit 300 may be implemented as a ToF camera. A ToF camera is a sensor capable of detecting a distance to an object and recognizing an object in three dimensions by irradiating light and measuring an arrival time of light reflected from an object. As shown in FIGS. 2 and 3 , the gesture sensor unit 300 is located on the side of the augmented reality glass device 10 and recognizes a hand moving at a distance within 20 mm (ie, sensing distance) from the sensor. to receive an input signal.

More specifically, the gesture sensor unit 300 recognizes an adjacent palm, and uses a gesture in which the palm moves in a first direction from the side of the wearer's face to the back of the head as a first input signal, and uses the gesture from the back of the wearer's head to the face. A gesture of moving the palm in the second direction may be received as a second input signal. That is, the gesture sensor unit 300 registers in advance to recognize the shape and movement direction of the palm, and the wearer opens the hand so that the palm is adjacent to the gesture sensor unit 300 and moves in the horizontal direction. Depending on whether it is from the back (first direction) or from the front (second direction), a wearing signal or a taking off signal may be respectively input.

The length adjusting unit 400 is connected to the strap unit 200 to adjust the length of the strap unit 200 by the operation of the motor 410 . As shown in FIGS. 2 and 3 , the length adjustment unit 400 is located on the back of the wearer's head when worn by the wearer, and the length of the strap unit 200 can be adjusted by the operation of the ultra-precision motor 410. . More specifically, the length adjusting unit 400 may adjust the length of the strap unit 200 using a rack and pinion method, including a pinion engaged with a rack implemented on the back of the head of the strap unit 200 and teeth. At this time, as the pinion rotates by the operation of the ultra-precision motor 410, both bands move in different directions, so that the lengths of the strap parts 200 on both sides can be reduced or increased.

The cushion part 500 is connected to the inner surface of the strap part 200 facing the back of the wearer's head, adheres closely to the back of the wearer's head, and may include a pressure sensor 600 therein. More specifically, as shown in FIGS. 2 and 3 , the cushion part 500 has a curved shape curved inward according to the back of the head, and the degree of curvature of the curved surface is deformed according to the length adjustment of the strap part 200. It may be a deformable structure that closely adheres to the back of the wearer's head. Here, the cushion part 500 is made of a polycarbonate or polypropylene material, and can be deformed according to the shape of the back of the wearer's head through the flexible nature of the material and adhered to it.
