Description

Wireless mouse with multi function

The present invention relates to a multi-function wireless mouse for conference and presentation, and more particularly, to operate without friction with the bottom surface, and a separate dedicated reflector pad provides an unnecessary mouse, and at the same time to prevent wear and malfunction of parts, The present invention relates to a multifunctional wireless mouse that has a laser pointer function that improves the convenience of time and allows a user to select a content displayed on a common large monitor in a conference and presentation session using a mouse and simultaneously indicate a distance.

In general, in order to select the data displayed on the screen of the computer, an input device called a mouse must be provided. Such a mouse moves a screen instruction console to the XY axis and clicks a corresponding execution program location to execute a desired program. will be.

The conventional mouse is mostly a ball mouse, and the ball mouse has a 2 centimeter sphere, which is in contact with the floor at the center of the mouse, and performs a cloud movement by the user's movement. Rotate the round bar. The index attached to the end of the round bar rotates to generate pulses as many as the number of rotations of the index, and transfers the movement amount to the computer so that the screen's instruction console moves to the X-Y axis.

In addition, the ball mouse and the ball are located on the upper part, and there is a track ball similar to the principle of operation. The pad is composed of the points of the reflector and the non-reflector and the infrared sense to receive the infrared light. Recognizes this and generates pulse as much as the moving distance, and moves the screen console to the XY axis. The optical mouse, which is to select the execution program, the method using the electric field and the magnetic field, the method of detecting the temperature of the finger, etc. Mouse for console control.

Most of these methods cover the palms and arms to control the movement of the letters and pictures so that it is not easy to draw the letters and pictures. In addition, it is not easy to perform precise position control for inputting pictures or texts, as well as generating signals that are incompletely transmitted by the contact of a mechanical device (especially when the bottom surface of the mouse is uneven). ) And short life.

In consideration of such a problem, recently, a pad reflecting light similar to the resolution of a user's computer screen, a dedicated pad composed of dots and lines of a non-reflective object, and an image reflecting light composed of dots and lines of a dedicated pad Provides a pen-shaped mouse with a built-in one-dimensional image recognition sensor that can recognize images, and can control the console for controlling the screen so that users who are skilled at drawing or drawing with a pen can draw letters or pictures easily. Techniques have been introduced to enable this.

However, such a pen-shaped mouse has to have a separate dedicated mouse pad, which is a problem that the incomplete signal is transmitted when the pad is not evenly flat.

As described above, when conducting a conference or various presentations using a computer operated by a mouse, there is a problem in that additional equipment or additional auxiliary personnel must be mobilized.

Therefore, the mouse function allows the descriptor or moderator to select and output the content to be described on the large common screen separate from the computer monitor, and the pointer function to take a part of the monitored content on the spot and explain it. It is required to be able to serve.

The present invention made in consideration of the above problems and requirements is to operate without friction with the bottom surface and to provide a mouse unnecessary extra dedicated reflector pad to prevent the wear and malfunction of parts, and at the same time improve the convenience of use On the other hand, the technical task of the present invention is to provide a multi-function wireless mouse that has a laser pointer function that allows the user to select the contents displayed on the common large monitor at the same time from the computer during conferences and presentations.

And, it is composed of a receiving unit 200 consisting of a USB input terminal 230 to be connected by the PC 300 and the USB port.

The present invention configured as described above generates an angular velocity or acceleration signal when the gyro sensor or the accelerometer sensor constituting the sensor unit 110 detects movement (movement), both of which are mathematically related physical quantities.

As described above, the physical quantity signal related to the position generated in the sensor unit 110 includes a unique frequency characteristic, and the low pass filter circuit of the filter unit 120 limits the range to an appropriate frequency for an optimal moving position. To ensure.

Thereafter, the amplifying unit 130 amplifies the fine frequency signal so that the output level is increased, that is, amplifies and amplifies a signal having an appropriate size in the optimum frequency range that the arithmetic and control unit 150 can process, and proportionally to the moving direction. Modulation method of increasing / decreasing the width of a pulse of a certain period is applied, that is, the pulse width is increased when the moving direction is in the forward direction, and the pulse width is decreased when the A / D converter 140 is in the negative direction. The resultant value is modulated so as to estimate how much the input device has moved in which direction by counting the pulse widths increased and decreased in the operation control unit 150, converting the resultant signal into a digital signal, and transmitting the result to the operation control unit 150.

The transmitted digital signal has a one-to-one correspondence with a moving position. When the arithmetic processing is performed by a processor programmed in advance in the operation controller 150, a position amount proportional to an exercise amount, that is, a position value (moved distance value) appears. As such, the calculated positional information is represented by two-dimensional signals of up, down, left, and right when used with a mouse.

Subsequently, when the 2D signal is amplified and transmitted from the high frequency transmitter 160 as a high frequency signal, the high frequency receiver 210 of the receiver 200 is received and transferred to the calculator 220. The processor converts the mouse movement signal (coordinate value) into a wired connection between the USB port of the USB input terminal 230 and the USB port of the PC 300 by wire. Reference)

The high frequency signal received by the receiver 200 undergoes the same process as the signal conversion of the mouse 100 so that the calculator 220 can perform arithmetic processing, which is the same as described above, and thus is omitted.

In addition, the present invention as shown in Figure 4, when operating the laser pointer button 175 of the switch unit 170, the operation control unit 150 sends the operation signal to the laser generating unit 180 and the laser generating unit 180 generates a laser beam to indicate a predetermined point (position) at a certain distance.

That is, the contents displayed on the common large monitor can be selected by a mouse in a computer conference and presentation, and the contents of the large monitor or the screen can be indicated from a distance.

The battery 190 used in the present invention is applicable to any small battery, and its model varies depending on the manufacturer and specifications.

In the present invention, reference numeral 176 is a channel button, and when the first operation, pressing the channel button 240 of the receiving unit 200 to match the receiving unit 200 and the channel (ID), which is the operation of another mouse It does not cause interference, which is a general frequency matching scheme.
