Problems solved by technology

[0005] The principle of using the optical mouse is to scan the sliding surface through the infrared sensor, and calculate the displacement by its refraction. Therefore, when the optical mouse touches the desktop with repetitive textures, such as wood grain, the infrared sensor is easy to misjudge its movement distance, causing the optical mouse cursor to jump when moving, making it impossible to precisely position the mouse cursor
[0006] In addition, when the auto-scroll function of the traditional mouse is activated, although the window can be automatically scrolled according to the direction the mouse cursor moves, it cannot precisely control the speed and direction of the scroll bar, resulting in trouble in use. many inconveniences

no. 1 example

[0018] The mouse with precise positioning function according to the first embodiment of the present invention includes a left button 100 , a scroll wheel 110 , a right button 120 and a microcontroller 200 .

[0019] Press the left button 100 and the right button 120 at the same time to make the mouse enter the precise positioning mode, and press the left button 100 and the right button 120 again to cancel the precise positioning mode. The functions of the cursor and the scroll wheel will be invalid. Even if you move the mouse at this time, the mouse cursor on the screen will not have any moving effect.

[0020] After the mouse enters the precise positioning mode, press the left button 100 once to send a signal to control the mouse cursor to move to the left to the microcontroller 200; press the right button 120 once to send a signal to control the mouse cursor to move to the right 200; the scroll wheel 110 scrolls up once, and sends a signal to control the mouse cursor to move...

[0024] FIG. 3 shows a schematic diagram of a mouse with a precise positioning function according to a second embodiment of the present invention. With reference to FIG. 3 , the mouse with a precise positioning function according to the second embodiment of the present invention will be described as follows.

[0025] The mouse with precise positioning function according to the second embodiment of the present invention includes an up button 300 , a down button 350 , a left button 400 , a right button 450 and a switch button 800 .

[0026] Press the switch key 800 to make the mouse enter the precise positioning mode, and press the switch key 800 again to cancel the precise positioning mode. Wherein, when the mouse enters the precise positioning mode, the functions of the original button click, cursor and scroll wheel will be invalid. Even if you move the mouse at this time, the mouse cursor on the screen will not have any effect of moving.

Abstract

The mouse with precise locating function includes several keys and one micro controller. The keys are used for the mouse to enter precise locating mode and to transfer cursor shifting signal. The micro controller connected to the keys receives the cursor shifting signal and controls the location of the cursor with one mouse cursor control software based on the signal for controlling the shift of the cursor.

Description

technical field [0001] The invention relates to a mouse, in particular to a mouse for precisely positioning a mouse cursor on a point or position. Background technique [0002] Faced with more and more ICs and surface mount components, a circuit board can also include hundreds, thousands, even tens of thousands, hundreds of thousands of tiny lines. Therefore, when using a traditional mouse to draw complex circuit diagrams, the surface For high-complexity designs, it is often impossible to easily click and drag to complete the drawing of the circuit diagram. For example, in the cumbersome steps of drawing a circuit diagram, it is often necessary to use the mouse to precisely position the mouse cursor. Move the mouse cursor exactly where you want it, so there's no quick and easy way to draw a diagram. [0003] In addition, the ball of the mouse is often caused by dirt and grease, causing the problem of insufficient mouse sensing accuracy. Therefore, the mouse will not move s...
