The present invention relates to a game interface device using a motion sensor, and more particularly, by detecting a user's motion using a low-cost motion sensor, not only can reduce manufacturing costs, but also maximizes the user's body. In addition to providing comfort, maximizing the realism of the game, it is possible to use to correspond to the mouse, keyboard and joystick, etc. without installing a separate application program, to improve the ease of use.

In general, a personal computer (PC) is configured with a variety of peripheral units (Peripheral Unit) for the user's convenience, the peripheral device is an output device such as a monitor (Pointer) and a printer (Printer), a keyboard (Keyboard) and And an input device such as a mouse.

The mouse, which is one of the input devices among the peripheral devices used in the PC, controls the movement of the pointer displayed on the monitor screen. (ball-mouse) is used, but when it is used for a long time, foreign matter gets stuck between the ball and the sensor, and an error occurs when the movement of the ball is detected by the sensor, which causes inconvenience of having to clean the inside of the mouse every certain period. There was a ham.

Herein, the pointer refers to a pointing cursor that visually moves in accordance with the movement of a mouse in an operating system that supports a Graphical User Interface (GUI).

In order to solve the above problems of the ball mouse, a ball is installed on the upper part of the mouse and a track ball mouse for rotating the ball by hand or an optical mouse using light is used. Infrared mouse and the like are also used.

On the other hand, in recent years, due to the popularization of the online game using the network and the activation of the game industry, a variety of games using the PC has been widely spread, especially the online game is rapidly developing.

Therefore, various peripheral devices for such online games, for example, a variety of gaming peripherals such as joysticks are used, the user by operating the keyboard, mouse and joysticks, such as online games, such as strategy games, competition games, racing games You will enjoy it.

In addition, in the case of the online game as described above, since a large number of users are connected and enjoy the game at the same time, the game is often played for a long time, as well as the mouse, keyboard or joystick continuously during the game. Must be operated.

Looking at the user's body structure, the most comfortable posture of the thumb upwards by the combined structure of the upper arm and the lower arm, the radial and ulna, the upper arm, but the mouse When used, since the back of the user's hand is facing up, if you use the mouse, keyboard and joystick as described above for a long time will be a burden on the wrist causing pain.

In addition, when the game proceeds by the operation of the racing game by the keyboard, there is a problem that the reality is lowered to inhibit the interest of the game.

Recently, in order to solve the problem of giving a burden to the body as described above, a cyber glove (Cyberglove) using an optical fiber gyroscope or a plate-shaped sensor has been used.

The optical fiber gyroscope is basically composed of a light source and a fiber coil (rotation sensing unit) wound around the optical fiber in a circular shape, and the light from the light source is divided into two lights after passing through the directional coupler and passed through the optical fiber coil to combine in the directional coupler. It is supposed to be.

When the optical fiber gyroscope rotates, the output of the photodetector is changed due to the phase difference generated between the two lights due to the Sagnac effect, and the rotation of the hand is detected by measuring the amount of rotation by measuring the change in the output intensity of the photodetector. And it can detect the movement and the like, it is also possible to detect the movement, such as bending of the finger by the sensor function of the optical fiber itself.

And in the case of the plate-shaped sensor by installing the sensor in the joint portion, by detecting the deformation of the plate-shaped sensor that occurs as the joint is bent, it is to detect the motion of the hand.

However, the cyber glove using the optical fiber gyroscope or the plate-shaped sensor as described above uses a high-precision sensor, greatly increasing the manufacturing cost, and the overall processing speed of the system is lowered due to a complicated data structure. There was a problem applied.

In addition, there is an inconvenience in that a separate application program must be installed in order to use the cyber glove, and if a software error occurs in the application program, there is a problem that the use of the cyber glove is impossible.

Therefore, an object of the present invention is to solve the above-mentioned problems, by detecting the user's movement using a low-cost motion sensor, not only can reduce the manufacturing cost, but also the maximum comfort to the user's body In addition, the present invention provides a game interface device using a motion sensor that can maximize the reality of the game.
