Description

VR glove {VIRTUAL REALITY GLOVE}

The present invention relates to a VR glove.

In the conventional general game, the user enjoys the game according to the game situation displayed on the screen by using a simple manipulator such as a joystick or a keyboard while viewing the monitor, so that the user can not experience the same situation as actually experiencing the game situation. However, when the virtual reality (VR) is applied to the game, the user can experience the five senses like the actual situation, thereby increasing the immersion of the game.

Virtual reality is created by interacting with a sensory system in a virtual environment built using a computer to indirectly experience situations that are difficult to experience directly in the real world due to physical and spatial constraints It is information activity field. When systems implementing virtual reality provide a virtual environment in which the user's viewpoint and operation are realized, it is generally assumed that the user changes the viewpoint or operation of the user in a virtual space or acts on behalf of the human body in the virtual reality space Through the presence of performing the environment.

In a virtual reality environment, interaction devices have been used to recognize various information of a user based on input sensor devices. For example, as soon as the ball lands on the golf club on the virtual screen, the space sensor or motion sensor attached to the golf club immediately analyzes the user's swing angle and putting posture, and the analyzed user information is immediately transmitted to the smart phone. We can make use of information and correct posture.

However, the output device, which is implemented in the form of a virtual reality glove for generating feedback signals such as reaction force, tactile sense, and stimulation information and transmitting the information to the user in reverse, is now in its infancy stage. The technology development that applies it is likely to grow.

Conventional general VR gloves have various sensors and gloves integrated into one body. Therefore, there is a problem in that the size of hand is different for each user, or the entire glove is changed when washing or repairing.

In this case, although the upper cover 200 is firmly attached to the base glove 100, It may be troublesome to repetitively attach and detach many times to make a mistake in selecting the attachment position in the process of attachment, and therefore, it is preferable that a plurality of pieces are provided for each specific position. For example, it can be formed evenly distributed on nails, bone nodes, and the back of a hand.

The lower portion of the lower cover 300 and the upper surface of the base glove 100 may be detached from the upper surface of the lower cover 300. [ And a second engagement claw surface 720 formed on a lower surface of the base glove 100. [

Although the lower cover detachable part 700 may be formed entirely between the upper surface of the lower cover 300 and the lower surface of the base glove 100, the lower cover 300 is firmly attached to the base glove 100, It may be troublesome to repetitively attach and detach many times to make a mistake in selecting the attachment position in the process of attachment, and therefore, it is preferable that a plurality of pieces are provided for each specific position. For example, it can be formed evenly distributed on nails, bone nodes, and the back of a hand.
