The above and other objects and advantages of the present invention will become more apparent from the following description of the preferred embodiments of the present invention with reference to the accompanying drawings, by persons skilled in the art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The digital sensor structure shown in FIG. 2 (B) includes a reference voltage supply layer 200 to which a Vcc reference voltage is supplied to the uppermost layer, a nonconductive layer 20 which contacts the outer surface of the glove, And a conductor layer 201 serving as an input / output port (I / O port) for providing '0' and '1' digital data between the reference voltage supply layer 200 and the nonconductor layer 202 . The layers may be arranged side by side at regular intervals. In the case of the nonconductor layer 202, the layer may be formed to protrude slightly toward the glove side. Each joint digital sensor having such a structure has a path for each layer and each path as shown in FIG. 2A.

FIG. 3 is a schematic block diagram of a virtual reality system capable of accommodating the glove shown in FIG. 2, and includes first to 14 digital sensors 301 to 305 attached to each joint as shown in FIG. 2 A reference voltage supplier 330 for providing Vcc of 5V to the glove 300 and the glove 300, a processor 310 for detecting the contents of the digital data output from the glove 300 by a predetermined calculation method, And a host computer 320 for applying the data to the virtual reality world when data is transmitted from the processor 310. [

In the virtual reality system configured as described above, when the digital sensor as shown in FIG. 2 is applied, the operation of the glove 300 is performed as follows.

That is, when the wearer wears the glove and the reference voltage is applied from the reference voltage supplier 330 and the user bends the finger as shown in FIG. 2 (B), the elastic conductive layer 202 The fingers are deformed into the same shape as the bent shape and directly press the conductor layer 201 existing in the upper layer. When the conductive layer 201 is pressed by the nonconductor layer 202, the conductor layer 201 is bent in the direction of the reference voltage supply layer 200 because the conductive layer 201 is provided to have a slight elasticity. When the conductive layer 201 is brought into contact with the reference voltage supply layer 200 by such a bending operation, a digital value of high (or low) level is output, and the output value is transmitted to the processor 310.

The processor 310 is composed of a processor such as a microcomputer and tracks the current user's hand movement state by a signal transmitted from the digital sensors 301 to 305 attached to the respective joints operated as described above. The tracked result is transmitted to the host computer 320 and applied to the virtual reality world.

As can be seen from the side view, the arrangement of the reference voltage supply layer 400, the conductor layer 401 and the non-conductor layer 402 provided in the digital sensor is in the order as shown in FIG. 2, The structure of the nonconductive material is different.

That is, in the side view, the nonconductor layer 402 having an elastic property protrudes in a right angle from the joint to the globe side, and the conductor layer 401 is in the form of a plate in which the center pin is fixed to the center of the protruded region of the non- (Or in the form of a tweezer with a center pin inserted in the center). As shown in FIG. 4, the digital filter has a reference voltage supply layer on one side and an I / O port layer on the other side of the non-conductive layer. The non-conductive material existing between the reference voltage supply layer and the I / O port layer is separated from the reference voltage supply layer and the I / O port layer when the linear or S-shaped curved shape or other fingers are not being flexed Or any other suitable structure.

As described above, according to the present invention, a digital sensor, which is attached to a glove for digital data input used in a virtual reality system and used for tracking a hand movement, is composed of a reference voltage supply layer, a conductor layer, and a flexible insulating layer, Is configured to be protruded toward the glove side so as to be sensitive to the flexing motion of the finger, so that it is possible to transmit the sensing result in a digital form without an analog / digital converter, simplify the sensing structure, and improve the price competitiveness of the glove There is also an effect.
