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

3 is a perspective view schematically showing a three-dimensional input device according to the present invention, Figure 4 is a cross-sectional view taken along the line A-A of Figure 3, Figure 5 is a cross-sectional view taken along the line B-B of FIG.

The three-dimensional input device of the present invention, as shown in Fig. 1, the stick 100 is installed so that the two-dimensional coordinate movement of the front and rear (z-axis direction) and left and right (x-axis direction) by the universal joint, and the stick The handle 200 is installed on the upper side of the handle 100 so as to be movable up and down (y-axis direction) and rotates at a predetermined angle, and is provided on the handle 200 and the pitch and roll of the virtual reality object. It includes a trackball 300 for detecting the movement of the.

And the stick 100 is a hollow shaft 110, the handle 200 is installed to be able to move up and down (y-axis direction) and a predetermined angle rotation, and one end of the universal joint 130 in the lower portion of the hollow shaft 110 It consists of a shaft 120 which is installed to be movable in the front and rear (z-axis direction) and left and right (x-axis direction) by the.

And the lower part of the stick 100 is provided with a first means for detecting the lean of the front and rear and left and right of the stick, the first means is a pressing plate 140 which is rotatably supported back and forth and left and right on the lower end of the shaft (120) And four switches 151 to 154 selectively installed by the pressing plate 140 at predetermined intervals in the front and rear and left and right directions about the pressing plate 140.

And second means for detecting a movement in three-dimensional coordinates between the handle 200 and the hollow shaft 110 of the stick 100, and a third means for detecting a yaw of the virtual reality object. It is provided with this predetermined interval.

The second means includes two switches 161 and 162 protrudingly installed on the outer circumferential surface of the hollow shaft 110 of the stick 100 at a predetermined interval up and down, and the handle 200 to be positioned between the two switches 161 and 162. It consists of a pressing piece 210 is formed to protrude on the inner circumferential surface.

The third means includes two switches 171 and 172 protruding from the hollow side 110 and the outer peripheral surface of the stick 100 at predetermined intervals, and are disposed between the two switches 171 and 172. It consists of a pressing piece 220 protruding from the inner circumferential surface of the.

Here, the pressing pieces 210 and 220 are formed long in the horizontal and vertical directions so as to operate the respective switches 161, 162, 171, 172 regardless of the movement of the handle 20 up and down.

And the hollow shaft 110 of the stick 100 is elastically installed by the spring 400 to the handle 200, a plurality of hooks on the inner peripheral surface of the handle 200 to fix the vertical movement position of the handle 200 A groove 230 is formed, and a locking protrusion 180 selectively caught by the locking groove 230 is formed on the outer circumferential surface of the hollow shaft 110 of the stick 100 corresponding thereto.

The three-dimensional input device according to the present invention configured as described above is operated as follows.

First, when the user grabs the handle 200 and tilts the stick 100 back and forth and to the left and right, four switches arranged in front and rear and left and right while the pressing plate 140 installed at the bottom of the stick 100 is moved back and forth and left and right. As the 151 to 154 are selectively operated, movement of the front, rear, left, and right two-dimensional coordinates (z and x axes) is performed.

In addition, the pressing piece of the handle 200 operates two switches 161 and 162 installed up and down on the hollow shaft 110 of the stick 100 by raising or lowering the handle 200 upward or downward. Movement to three-dimensional coordinates (y-axis) is made.

And when the handle 200 is rotated to the left and right, the pressing piece 220 formed on the inner circumferential surface of the handle 200 is provided with two switches left and right at predetermined intervals on the hollow shaft 110 of the stick 100 corresponding thereto ( As the 171 and 172 are selectively operated, rotation about the y axis, that is, movement in the yaw direction is performed.

And while holding the handle 200 by rolling back and forth with the thumb using the track ball 300 installed on the upper portion of the handle 200 is rotated about the z-axis, that is, the movement in the roll (roll) direction, and also Rolling the track ball 300 installed on the upper part of the handle 200 to the left and right by using a thumb, the rotation about the x-axis, that is, the movement in the pitch (pitch) direction is made.

As described above, according to the three-dimensional input device of the present invention, the three-dimensional coordinates (x, y, z) by a simple operation of holding the handle and tilting the stick back and forth and left and right or moving the handle up and down with respect to the stick. Movement is possible and the movement in the yaw, roll, and pitch direction is achieved by a simple operation of rotating the handle left and right or rolling the trackball provided at the top of the handle back and forth and from side to side. Since the operation is simple, compared to the conventional method, the operation is simple, the use is convenient, and the structure is simple, so that the price can be lowered.
