Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, FIG. 1 is an exemplary view of a glove having a digital sensor as an input / output port (hereinafter referred to as an I / O port) of each finger except the thumb according to the present invention. The digital sensors 101 to 105 are attached to the portion, and a reference voltage (hereinafter, referred to as Vcc) is applied to the end of the thumb.

A digital sensor that can be mounted in a position as shown in FIG. 1 is a plate made of a digital sensor and a conductor which performs a function corresponding to a general small on / off switch or an on / off switch. (Plane) can be implemented.

FIG. 3 is a block diagram of a glove interface device for digital data input according to the present invention. As shown in FIG. 1, Vcc 301 hanging on the bottom end of the thumb and the bottom end of the index finger are shown in FIG. 1. Digital sensor 302 attached to serve as the I / O port of the index finger, digital sensor 303 attached to the bottom end of the middle finger to serve as the I / O port of the middle finger, ring finger Digital sensor 304 attached to the bottom end of the finger to serve as the I / O port of the ring finger, digital to serve as the I / O port of the little finger attached to the bottom end of the pinky finger A sensor 305, a glove 300 with a three-dimensional sensor 306 attached to the back of the hand as shown in FIG. 2, a Vcc 301 and digital sensors 302 attached to the bottom side of each fingertip. 305) and the three-dimensional sensor ( A processor 310 for detecting interaction with the 306 and a host computer 320 operated to provide a virtual reality corresponding to a user according to a signal transmitted from the processor 310.

The glove interface device for digital data input according to the present invention configured as described above is operated as follows.

That is, when any one of the digital sensors 302 to 305 attached to the end of the little finger comes into contact with the Vcc 301 hanging on the end of the thumb, the finger makes contact. A loop in which electricity flows between the thumb and the thumb is formed so that the processor 310 can detect a finger that has made contact.

For example, when a contact is made between the thumb and the index finger, the Vcc 301 caught on the thumb turns on the digital sensor 102 serving as an I / O port on the index finger, thereby causing the processor 310 to thumbs up. Make sure that you are in contact with the index finger. In this way, the processor 310 detects the interaction between the fingers by the contact state between the thumb and index finger, the thumb and middle finger, the thumb and ring finger, the thumb and the little finger.

X, Y, and Z-axis values applied from the 3D sensor 201 and yaw (moving (or rotating) in both directions in the horizontal direction), pinch (sliding state in the vertical direction), and roll (tilting to one side) The current hand position and rotation state are detected. In order to perform such detection, the processor 310 is composed of a circuit such as a microcomputer.

The contact state between the fingers and the position and rotation state of the hand detected by the processor 310 are transmitted to the host computer 320. The host computer 320 controls the operation of the hand on the object in virtual reality by the data transmitted from the processor 310. For example, when information on the contact between the thumb and the index finger is transmitted from the processor 310, the host computer 320 performs a task of picking up an object in the virtual reality world, and state information about the contact between the thumb and the middle finger is displayed. When the transmission is performed, the object is enlarged, and when the state information of contact of the thumb and the ring finger is transmitted, the reduction of the object is performed, and the state information of the contact of the thumb and the little finger is transmitted. Rotate the.

4 is another embodiment of the digital sensor and the reference voltage (Vcc) attached to the glove for the interaction as described above between each finger, covering a certain area of each finger end with a conductor, the constant of the thumb end The area is set as an area capable of providing Vcc, and the Vcc supply area assigned to the thumb is an example provided to be equal to the conductor area provided at the end of each finger.

When the glove is configured as described above, the processor 310 may cover not only the interaction between the thumb and each finger but also the interaction between two or more fingers as described above. That is, when the thumb and the end of the middle finger is in contact with the thumb, a loop through which electricity flows is formed in both fingers, so that the processor 310 may detect that the thumb, the index finger and the middle finger are in contact with each other. In addition, it is possible to detect a state where all four fingers are in contact with the thumb.

As described above, according to the present invention, Vcc is applied to the thumb of a data glove applied to a virtual reality system, a digital sensor or a conductor is attached to the bottom or front of the end of the remaining fingers, and a three-dimensional filter is attached to the hand. By doing so, it is possible to more naturally reproduce the interaction between the fingers and the position of the hand on the object in the virtual reality system. In addition, the glove implemented as described above has an effect of detecting an electrical relationship between fingers by forming an electrical loop even when a metal object is held in a worn state.
