Abstract: The present invention relates to a method for user image data matching in a metaverse-based office environment and, more particularly, to a method for user image data matching in a metaverse-based office environment, the method comprising: a chat group identification step of identifying a camera viewpoint of a target user in a virtual space, and identifying whether a chat group for users included in a virtual image of the camera viewpoint is included; and a user image matching step of matching user images to avatars of respective group users included in the chat group, the user images being obtained by image-capturing the group users in real time.

Abstract: The present invention relates to a method for user grouping in a metaverse-based office environment and, more particularly, to a method for user grouping in a metaverse-based office environment, the method comprising: a target user identification step of identifying a camera viewpoint of a local user in a virtual space, and identifying target users included in a virtual image of the camera viewpoint; and a user grouping step of grouping target users satisfying a configured grouping condition from among the target users, on the basis of avatar positions and gaze directions of the local user.

Abstract: To prevent lateral slip of core metals and vertical vibration of track rollers and improve bendability of a crawler main body between core metals.

Abstract: An elastic crawler capable of effectively preventing an occurrence of vibration, noise and cracks during driving while improving durability is provided. The elastic crawler includes a coupling portion arranged at equal intervals in a circumferential direction at a center in a left and right direction of a crawler body, a steel core arranged in the left and right direction between adjacent coupling portions in the circumferential direction of the crawler body, and two rows of left and right lugs installed on an outer periphery of the crawler body, wherein each of the rows of the lugs includes driving lugs arranged in an oblique direction with respect to the steel core, and each of the driving lugs overlaps with two adjacent steel cores in the circumferential direction.

Abstract: An ultrasonic linear motor according to one embodiment is disclosed. The vibrating body includes an elastic body and a first piezoelectric element and a second piezoelectric element which are attached to two surfaces of the elastic body, a first weight and a second weight which are disposed on two side end portions of the vibrating body, a moving shaft which is coupled to a central portion of the vibrating body and moves according to a displacement of each of the piezoelectric elements, and a moving body which is fitted to the moving shaft and moves on the moving shaft.

Abstract: To prevent vertical vibration of track rollers as much as possible when transferring between overhanging portions of each core metal while securing the flexibility of a crawler main body. The present invention includes core metals 10 embedded in a crawler main body 9 at substantially equal intervals, and rolling paths 12, 13 for track rollers arranged on both sides in a crawler width direction of an anti-tread side of the crawler main body 9, and includes overhanging portions 24 to 27 on both sides in a crawler rotation direction of each core metal 10, overhanging from each core metal 10 toward both sides in the crawler rotation direction to support each of the rolling paths 12, 13. The respective overhanging portions 24 to 27 corresponding to the respective rolling paths 12, 13 of each core metal 10 are arranged such that at least tip portions are arranged so as to shift in the crawler width direction within a width of each rolling path 12, 13.

Abstract: According to an embodiment, a mousepad comprises a cover layer and an integrated keypad. The cover layer has a lateral extension and an upper surface which is usable for placement (placing, putting down) of a computer mouse. The keypad covers a part of said lateral extension. In an area not covered by the keypad there is a mouse parking area. The mousepad comprises a mouse detector associated with the mouse parking area and a corresponding control unit. The control unit is configured such that the keyboard gets activated when the mouse is inside the mouse parking area and gets deactivated when the mouse is outside the mouse parking area.
