The input devices are those devices and components that allow you to enter information to the processing unit; some known examples of all are the keyboard , the mouse (also called mouse ), the scanner , the webcam ( webcam ), the stylus and microphone ; the way in which the user interacts with them is very varied and has, in each case, a different purpose, which can be the digitization of a text or an image, the capture of a video sequence or the recording of a song , among many other possibilities.

What is Mechanical Mouse: Definition

In general, mice are made of plastic and have a mechanism that allows them to detect the movement that the user makes in two dimensions: the X axis and the Z axis, which can be translated as lateral translation (from right to left) and forward or backward. When you move the mouse on a flat surface, this movement is reflected on the screen through a pointer , arrow or cursor .

It should be mentioned that there is a particular learning curve when using a mouse for the first time. Young children, as in many other fields, seem to find it very easy and it is common that in a short time they surpass their elders in dexterity. However, for a person of a certain age, who has never approached technology , it is necessary to cross certain barriers.

The main difficulty lies in understanding that the movement carried out on a horizontal surface is translated into a screen, generally in a vertical position. On the other hand, the user must get used to lifting the mouse and repositioning it every time it reaches the limit of the desktop and wants to continue in the same direction .

Functions of  Mechanical Mouse

In addition to transmitting movement to the screen, the mouse has a minimum of two buttons , which allow the user to select different options, which are specific to each operating system and the program being used. The actions that a person can perform with these keys and with the mouse are cataloged and the computer analyzes them at all times to know how to respond; some possibilities are:

• click : press any of the buttons and release it immediately, although the time it can be held down is configurable;
• double click : the same as the previous case, but repeated in an adjustable time interval ;
• hold down ; release : the system must know the exact moment in which a button is released, since there are applications that rely on this event to execute a certain function;
• drag : indicates that the mouse is moving while one of the buttons is being pressed;

According to the technology on which they base their operation, there are different types of mouse. The mechanical mice have a plastic ball in their lower part, which moves two wheels according to the displacement on the flat surface, and this is immediately translated into information of movement through the X and Z axes, mentioned above.

Types of Mouse

Optical- type mice , on the other hand, have a sensor at the bottom, which photographs the surface on which it is located and detects variations in the position of the device.

The laser mouse, on the other hand, is the most sensitive and precise, since it has a high resolution laser instead of the beam of light of optical technology, and works on a greater variety of surfaces, regardless of its uniformity as well as in the two previous cases.
