The present invention relates to a wireless mouse and a driving method thereof, and more particularly, by selecting a coordinate point of a specific position in space, sensing the selected coordinate point, and creating a virtual pad to perform a mouse function in the virtual pad. The present invention relates to a wireless mouse and a driving method thereof, which can conveniently control a computer without interruption of a conference and a presentation.

In general, a user uses an input device such as a keyboard and a mouse to use a computer.

The input device of the computer has been developed into a new device with the focus on the convenience of the user since the computer was developed.

A mouse is an input device that selects and clicks an icon and a menu bar displayed on a computer screen to view its data or to execute and install a program.

Conventional mice are mostly ball mice, and the ball mouse is open at the center of the lower part of the mouse, and the ball jumps out to the open area to move according to the movement of the user.

According to the movement of the ball, the round bar that is in contact with the ball is rotated, and the index attached to the round bar end is also rotated.

The pulse signal of the movement amount of the mouse is generated and transmitted to the computer as much as the number of revolutions of the index, and the computer moves the screen indicating console to the X-Y axis.

An improved mouse in this ball mouse is an optical mouse.

The optical mouse uses an infrared sensor to detect the movement of the mouse and move the on-screen console.

Computers, on the other hand, are used to conduct meetings and explain materials to the public.

At this time, the conventional computer input device as described above has the following problems.

In other words, the presenter has to come to the position of the computer during the meeting and explanation, and click the mouse and keyboard in order to turn the next page of the material, causing interruption of the meeting and explanation, and the user feels uncomfortable.

In order to solve the above problems, the user selects a coordinate point of a specific location in space, senses the selected coordinate point, and creates a virtual pad to perform a mouse function on the virtual pad, thereby providing a meeting and presentation method. An object of the present invention is to provide a wireless mouse and a driving method thereof that can conveniently control a computer without interruption.

It is another object of the present invention to provide a wireless mouse that allows a user to conduct a conference and present a conference more conveniently by adding a laser point function.

A first preferred aspect for achieving the above objects of the present invention is

A key input unit capable of selecting a specific position in space and generating a signal for the selected specific position;

A control unit which receives a signal generated from the key input unit and generates a control signal;

A gyro sensor for detecting a coordinate point by a control signal of the controller;

There is provided a wireless mouse configured to include a wireless transmitter for wirelessly transmitting a signal for a coordinate point detected by the gyro sensor.

A second preferred aspect for achieving the above objects of the present invention is

Generating, by the key input unit, a signal for a specific position selected in space;

Inputting a signal generated by the key input unit to a control unit;

Outputting a control signal from the controller to a gyro sensor;

Detecting, by the gyro sensor, a coordinate point for a specific position in the space and outputting a signal for the coordinate point;

The wireless transmitter is provided with a method of driving a wireless mouse, comprising the step of transmitting a signal for a coordinate point detected by the gyro sensor to a computer.

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

1 is a schematic side view of a wireless mouse according to the present invention, in which the first to third buttons 121, 122, and 123 protrude out of the case 110 of the wireless mouse 100.

The first and second buttons 121 and 122 are buttons for performing a normal mouse function, and the third button 123 is a coordinate point setting button for creating a virtual pad.

That is, the wireless mouse of the present invention clicks on the third button 123 every time the user moves the wireless mouse to another position in space, finds the coordinate point of the clicked position, and creates a virtual pad. The mouse functions on the pad, providing convenient computer control without interrupting meetings and presentations.

2 is a circuit block diagram of a wireless mouse according to the present invention, in which the circuit device 150 of the wireless mouse can select a specific position in space and generate a signal for the selected specific position; A control unit 152 which receives a signal generated by the key input unit 151 and generates a control signal; A gyro sensor 153 for detecting a coordinate point with a control signal of the controller 152; It comprises a wireless transmitter 154 for wirelessly transmitting a signal for the coordinate point detected by the gyro sensor 153.

The wireless transmitter 154 preferably transmits a signal through Bluetooth or an Infrared Data Association (IrDA).

The IrDa is a wireless data communication using infrared rays, and the Bluetooth is a proximity wireless data communication standard proposed for transmitting and receiving data at high speed using a radio frequency (RF) without a physical cable in various electromagnetic periods. By adopting CVSD (Continuous Variable Slope Delta Modulation), it has the advantage that it is possible to transmit not only text data but also voice in all directions without space limitation.

Referring to FIG. 1, when the third button 123 of the mouse is clicked by the user, the key input unit 151 generates a signal.

That is, when the user selects a specific position in the space, the key input unit 150 generates a signal for the specific position in the space.

The signal generated by the key input unit 151 is input to the controller 152, and the controller 152 outputs a control signal to the gyro sensor 153.

The gyro sensor 153 detects a coordinate point of the position of the wireless mouse in which the user clicks the third button 123, generates a signal for the coordinate point, and transmits the wireless transmitter 154.

Here, the gyro sensor 153 may detect the location information of the wireless mouse according to the present invention.

The wireless transmitter 154 transmits a signal for the coordinate point detected by the gyro sensor 153 to the computer 170.

At this time, the computer 170 should have software installed that creates a virtual pad with three coordinate points at different locations in space.

Here, since a plane can be made of three coordinate points at different positions in space, the software for creating a virtual pad can be simply implemented in a conventional technology level, and various software can be designed with various algorithms. As such, the description thereof will be omitted.

In addition, in the present invention, since the mouse operation can be easily implemented by conventional techniques, a detailed discussion is omitted.

In addition, the specific location of the space is at least three or more, and the computer forms a virtual pad including the at least three or more specific location coordinate points.

With the configuration as described above, the wireless mouse of the present invention creates a virtual pad in the space in front of the user so that the user can perform the mouse operation with the wireless mouse.

This surface becomes the virtual pad 200.

That is, since the first to third coordinate points 211, 212 and 213 have three coordinate points, virtual pads can be freely made in space.

Here, the virtual pad 200 is a two-dimensional virtual pad, it can also form a three-dimensional virtual pad.

At this time, the three-dimensional pad is also formed of three coordinate points.

That is, the surface perpendicular to the two-dimensional virtual pad (plane formed of three coordinate points) is defined as the Z axis, the axis increasing in the direction opposite to gravity on the virtual pad is defined as the Y axis, and perpendicular to the Z axis and the Y axis. Setting one axis to the X-axis completes a user-centric three-dimensional virtual mouse pad.
