The mouse belongs to an external input device of the computer, and it is also an indicator of the vertical and horizontal coordinates of the computer display system. It is named after its resemblance to a mouse. The mouse is not only an essential peripheral for operating computers, but also an indispensable weapon in the hands of game players.

Especially for game players, the importance of the mouse is undoubtedly greater than that of the keyboard, and mouse precision and response speed are critical for traditional FPS games or MOBA games.

However, due to different usage habits and palm sizes, everyone has different definitions of mouse usability standards. Comfortable appearance design, mouse size, cool RGB light effect, multi-functional buttons, connection methods, etc. should be paid attention to when purchasing.

Mouse size and mouse grasping method

If you want to select a mouse that is suitable for you in all directions, you can generally analyze it from the aspects of hand length, grip habits, mouse weight, mouse internal composition, mouse brand, etc.

The length of the palm determines whether you should use a big hand mouse or a small hand mouse. It is generally stipulated as follows. If the distance from the tip of the middle finger to the wrinkle at the end of the palm is more than 19cm, it is suitable for a 120mm-130mm long mouse. If the length of the palm is less than 19cm, it is better to choose a 115mm-120mm long mouse.

In addition, to obtain a comfortable hand feel, the user's grip on the mouse is also very important, and it can be roughly divided into three types.

The first is prone grip, that is, the palm will fully contact with the mouse. Its advantage is that it will not be tired after holding it for a long time, and it is suitable for small partners who work for a long time.

The second is grasping. It can be generally understood that only the fingers and some palms have contact with the mouse. Those who can use this grip are generally playing games. The third type is pinching, that is, only the fingertip of the finger contacts the mouse, and a long grip will cause fatigue.

Among them, prone grip is more suitable for right-handed engineering mouse, while grasping and pinching are suitable for left-handed and right-handed symmetrical mouse.

The internal structure of mouse

As for the composition of the mouse, generally speaking, the mouse is composed of shell+inching+wheel+sensor+motherboard+RGB lamp, and the core components are inching, wheel and sensor.

The inching is similar to the shaft of the keyboard, which is the process of pressing to generate an electrical signal and releasing it to reset. You will be familiar with the scroll wheel. The sensor is also called the engine. Its function is simple, but it is also very important.

It mainly converts the physical signal of mouse movement into a digital signal and sends it to the host to realize the movement of the cursor on the corresponding screen. It also has two most important parameters: sampling rate and rate of return, which are the parameters that everyone must look at when buying a mouse.

Inching

Among them, the core parts are the inching, roller and sensor. Here is a little popular science mouse inching. It is similar to the shaft of the keyboard to a certain extent. It is composed of a pressure handle, a dust cap, a metal spring, a terminal and a base.

When we press, the cover plate of the mouse shell contacts the lower terminal pin (once) by squeezing the "pressure handle", and then the current will be connected to send an electrical signal (once). After loosening, the metal spring will reset and the circuit will be disconnected. The mouse failure, mouse double click and other situations we often encounter when using the mouse are generally related to inching.
