Abstract

A mouse with an analog signal speed-changing key and a speed changing method of the speed-changing key are disclosed. The mouse includes a speed-changing key arranged on the surface of the mouse shell for the user's finger to perform downward pressing or reverse release, and a speed-changing key circuit. The drop generated by vertically pressing down the speed-changing key from the original position to the deepest position is divided into equidistant N segment strokes such that each stroke is defined as a stroke gear with the deepest position being the Nth stroke gear. The speed-changing key circuit is electrically connected with the mouse circuit for sequentially generating corresponding N voltage change values according to the N stroke gears of the speed-changing key, such that the existing circuit of the mouse can detect the N voltage change values and then correspondingly convert the values to generate N characteristic gears from low to high, such as the mouse CPI gear, the volume gear, the game racing throttle gear, the game shooting speed gear, the game running speed gear and so on. When the user is pressing down vertically on the speed-changing key to switch from the nth stroke gear to the (n+1)th stroke gear, the characteristic gear is raised from a lower characteristic gear to a higher characteristic gear by one gear. When the user reversely releases the shift button from the (n+1)th stroke gear to the nth stroke gear, the characteristic gear is reduced from a higher characteristic gear to a lower characteristic gear by one gear, allowing the mouse to achieve the usage effect of instantly adjusting the characteristic gear.

Description

Mouse with analog signal shifting key and shifting method thereof

The invention relates to a mouse, in particular to a mouse with an analog signal shifting key and a shifting method thereof, which is provided with a shifting button on the mouse for the user to press forward or reverse. Loosen, so that the mouse can achieve the effect of instantly changing the characteristics such as the mouse CPI value, volume, game throttle speed, game shooting speed, game running speed and other characteristic gears.

The mouse is used to perform functions such as input coordinates, point selection, up and down (front and rear) or left and right scroll animation surfaces. The common roller type mouse 10 is illustrated in Figure 1 but not used. To limit the invention, it has a top surface 11, a left button 12 is disposed in the left front section of the top surface 11, a right button 13 is disposed in the right front section of the top surface 11, and the left and right buttons 12 are A central roller 14 is disposed between the 13 and the 13th.

When using a computer, sometimes you have to switch or open the window, sometimes you have to switch to open the main screen or other screens, and sometimes you need to perform other operations such as restarting, searching the Internet, etc. In general, to achieve these operations, the operator It is necessary to simultaneously press a plurality of keys on the keyboard to be combined, so that the convenience for the operator (user) is relatively insufficient, which is disadvantageous for the operator to perform long-term operations. In order to overcome the above disadvantages, there has been a prior art in the art to add at least one hot key to the mouse, which is provided with at least one hot key on the outer surface of the mouse. These hotkeys define their function or characteristics as needed. However, the hot keys set by the prior art, regardless of the functions or characteristics defined by the hot keys, belong to only one switch type button, that is, the key circuits of the hot keys are electrically connected to the original mouse circuit. Connection, but the functions or characteristics of the hot keys are set in the mouse circuit (such as the integrated circuit provided on the mouse circuit board) by software or firmware design technology, and the mouse is on the mouse. The hotkey is only used to operate its on/off action, and can not be further used to instantly modify the use function or characteristic defined by the hotkey to different degrees of use. The function of use is the characteristic gear as described later in this case.

This case relates to a mouse with analog signal shifting key. Although the shifting key can be regarded as a hot key, the shifting key of this case is not a switch (on/off) type button, and it has the characteristics of instantaneous modulation. The function of the gear, the characteristic gear referred to in this case refers to the function of the corresponding performance when a certain characteristic or function (such as the CPI/Counts Per Inch characteristic of the mouse described later) is adjusted to different degrees. Such as: mouse CPI gear, volume and size gear, game racing throttle speed gear, game shooting speed gear, game running speed gear, etc. but not limited. Here, the CPI characteristics of the mouse are taken as an example: CPI (Counts Per Inch) represents the resolution of the sensor sampling every 1 inch (about 25.4 mm) of the mouse. Whether it is an optical mouse or a laser mouse, while moving the mouse, the sensor inside the mouse will continue to record and record, and after analyzing and processing, determine the direction and distance of the mouse's displacement, thereby changing the computer screen. The location of the upstream target. In other words, it is the number of coordinates that the mouse can recognize when it moves 1 inch. Each coordinate represents a point, so the higher the CPI value of the mouse, the more points can be identified within the same distance, and the closer the player can operate the mouse's real movement. According to the principle of mouse CPI, at the same distance, high CPI can store more information, and it can slide more. The detailed trajectory of the mouse movement is completely recognized. In this case, the higher the CPI value of the mouse, the faster the movement speed of the cursor.

In the mouse field, although the mouse with the CPI value selection key exists, the known CPI value selection key or its modulation mechanism is set by the manufacturing end before using the mouse, such as the CPI value. The preset is divided into 4 segments such as 600, 800, 1000, 1200, and a multi-stage control button or a cycle button is arranged on the mouse for the user (player) to adjust or cycle the selection, that is, During the use or operation of the mouse, the conventional mouse can't make the instantaneous adjustment of the moving speed of the upstream screen of the computer screen with the needs of the user (or the player), for example, in the design drawing or the esport game. At this time, the user cannot instantaneously change the CPI value to achieve low-speed accurate point selection or aiming and fast moving efficiency.

As can be seen from the above, it is known that a mouse having various types of hot keys defining functions, such as the above-mentioned mouse having a CPI value multi-segment control key or a cyclic type button, not only belongs to the simple three. Switch (on/off) buttons, and in actual use it is more difficult to meet the needs of users, especially when designing drawings or computer games or games (such as game operations). This case is to solve the shortcomings or problems that the conventional mouse can not instantly adjust the various characteristic gears of the computer (such as the moving speed of the cursor), and propose a solution. In this case, a analog signal shifting key is set on the mouse (such as The cursor moves the shift key), so that the mouse can use the analog signal shifting button to change the gear of the characteristic at any time during the use (such as the cursor moving speed gear), when the analog signal shifting key (such as a cursor) When the moving shift key is slowly pressed forward, its corresponding characteristic gear (such as the moving speed gear of the cursor) will increase linearly. When the analog shifting key (such as the cursor shifting key) is slowly reversed When the release is released, the corresponding characteristic gear (such as the vernier moving speed gear) will be linearly reduced, thereby improving the efficiency of the mouse, for example, in design drawing, In the esport game, the analog signal shifting button (such as the cursor shifting key) can be used to achieve low-speed accurate point selection, aiming, and fast moving.
