The current multimedia industry places high priority on making life easier for humans. In order to enhance human convenience, it can be achieved through miniaturization and complexation, which is possible when the efficiency of the device is maximized through organic and effective grafting of various functions.

Today's multimedia industry, represented by computers, tablets, mobile devices, handheld devices, and the like, is accelerating the pace of development due to the development of radio communication technology.

However, despite the speed of development of such a multimedia industry, a conventional multimedia device must operate together with a conventional input device including a keyboard, a scanner, a tablet table and a pen, and the like;

Such conventional input devices are bulky and inconvenient to carry;

In addition, independent processing and storage of information cannot be performed without a host device;

In particular, the thickness or adjustment of lines is not possible with the input device alone. When performing graphics, CAD, pictures, etc. that require them, the thickness of the lines must be specified through a computer program. As you work, it becomes a barrier to repeating unnecessary actions.

In order to solve the conventional problem, a research on a pen type, which is a new type of input device that can be input only by a pen, has been actively conducted. Such a pen-type input device uses optical (US Patent 5227622, US Patent 5166,668, etc.), a method of detecting the rotation of the ball by friction by mounting a small ball on the pen tip (US Patent 5371516, US) Patent 5210405, U.S. Patent 5,931, U.S. Patent 5027115, etc.), a method of using mechanical characteristics such as writing pressure, acceleration, writing direction, etc. when writing letters (U.S. , Etc.), and a three-dimensional mouse method (US Pat. No. 5,329,276, US Pat. No. 4,518,201, etc.) capable of inputting data without spatial limitations using angular velocity and acceleration sensors.

For generating electromotive force, the electromotive force can be generated by pressing the vertical pressure which is an essential element generated when the user uses it, the resulting rise of the circular electrode plate, and pressing the positive pole installed inside the button when pressing the second button. Due to the phenomenon of falling, there is no separate solution to the problem that the contact with the circular electrode plate installed in the lower part may cause a large error in sensing;

Whichever method you turn on or off, the pen tip is always located outside, and there is a problem that it is difficult to use in the existing tablet table due to the structure in which ink comes out when pressure is applied to the pen tip that protrudes out, but there is a separate solution for this. Not presented;

The present invention relates to a USB brush-pen drive that can be used as a device for inputting information such as characters, symbols, patterns, etc. in a general computer, tablet, mobile communication device, handheld device, etc .;

In order to generate such data by measuring the movement or displacement of an object using speed, angle, etc., it can be implemented in a host device and can be transmitted and stored as needed. It is possible to generate data through an acceleration sensor based on the Coriolis Effect, which is widely used in general;

Equation for generating such data is as follows.

The basic formula for defining the Coriolis Effect is: 2m (Angular Velocity) Velocity in a Rotating Frame

A lamina is applied to the movement of Particle P along the path of the Lamina. Therefore, the total acceleration ap that also moves the path is obtained from the following equation.

Where ap / path = acceleration of P that correlates to a Path that is considered fixed,

aM = acceleration of point M, where M is on Path and instantaneously coincides with P

Vp / path = velocity of P correlated to point M, on path, instantaneously coincides with P.

This speed can only work along the tangent to the path that P is moving in the body.

ω = Angular velocity of the path or lamina

2ω x Vp / path = Component of Coriolis: The direction of the Coriolis component is taken by visualizing the rotation in the plate of the Vp / path layer through a right angle with the same meaning as ω. The velocity V can be calculated | required using the acceleration (a) obtained by this.

The velocity can be used to find the displacement S, which is the distance the real object has moved.

The present invention uses a separate angular velocity sensor as shown in FIG. 8 to measure the positional displacement of the object using the acceleration as described above, and to correct the uncertain constants c1 and c2 inevitably generated during such measurement. The error can be corrected by measuring the angle.

The present invention may be represented by an example as shown in FIG. 8 as a method of correcting such an error.

When the angular velocity sensor is arranged in three directions of the X, Y, and Z axes, the three-dimensional angle of the object can be measured, and using this, the error generated by the acceleration sensor can be corrected;

The real object exists in the A2 position through the movement path, but it is recognized that the real object exists in the A2 position due to the error of the acceleration sensor, and this error is corrected to be A2 when the angle of movement is measured by using the angular velocity sensor. It is possible to do;

The present invention relates to a USB brush-pen drive that can generate more accurate position displacement data through such measurement and correction, thereby making it easier to input characters, symbols, drawings, and the like.
