Computer mouse - what is it?

A computer mouse is a very necessary data input device; it is convenient to work with. Not All They fully understand what it is, how to work with it, and most importantly, what varieties can be seen on store shelves. Let's look at these questions. 

What is this is that?

A computer mouse is a manipulator that transforms movements into a control signal. In simple words, movements, which you carry out the mouse are converted into signals, which perceives and recognizes PC. For the modern user, this manipulator is an integral part of the computer. If you need to copy documents, highlight a section of text, or move documents from one folder to another, the mouse will be your best assistant. 

Of what consists of 

The manipulator consists from: 

• Wheels scroll. With its help, the user has the ability to move information on the screen by scrolling the sheet up or down.  
• Keys Their purpose: activation or opening of objects, their capture and movement. 

REFERENCE. This device is provided in most models of computer mice.

• There is a special sensor on the back side. It is necessary in order to read movement on the surface. Depending on the type of manipulator, this May be Many people are familiar with a ball or a laser scanner.It depends on what mouse you are using do you use .
• Also Wired mice have a cord by means of which connection to a PC is carried out. Wireless models have a compartment Where batteries are installed. 

Types of computer mice

Given The device has been modified and improved over the course of its existence. Today it is an easy-to-use mouse that instantly responds to human actions. For various purposes, experts recommend choosing different types of computer mice, because your choice will ultimately determine the ease of use, as well as your work result. Some of them are suitable for games, others for work, creating drawings and more. On store shelves you can find the following types of computer mice: 

• Mechanical. They are now practically no longer used, as options with better characteristics have appeared. The tracking sensor is represented by a steel ball, which is rubberized, as well as other elements necessary for correct operation. During the movement, the ball rotates, as a result of which the rollers are pressed against it, the movement is recorded, and then the information transmitted corresponding sensors that are responsible for recognition turn signals. This is how the mouse works with the computer. 
• Optical. This option uses a small camera that takes over a hundred frames per second to read the surface on which the mouse is moving. In order to improve the quality of detection, a powerful LED is used; it is mounted at the bottom of the device at a slight angle. You can see its glow. 

• Laser. The operating principle is very similar to optical devices. An infrared laser diode is used for illumination. This solution allows you to increase the accuracy of movement detection. Can work on almost any surface. 

• Sensory. There are no buttons or scroll wheel. Control is carried out using gestures. This is a new type of mouse that is very simple and easy to use. 

• Induction. Their operation is ensured by the use of inductive energy. When working, be sure to have a mat, which is something like a working tablet. 

• Trackball. There are no buttons on them, but for control they use flipped over the ball from which the mouse got its interesting name. This is an unusual model that is found on the shelves infrequently. You can purchase them either in specialized stores or in online stores. 

• Gyroscopic. In this model, cursor positioning Maybe thanks to the gyroscope. Information is read both from the surface and from the surrounding space. 

In addition, computer manipulators are divided according to the connection method: 

• Wired. They are connected to a PC using a USB or PS/2 cable. 
• Wireless. Connection Maybe thanks to Bluetooth. 

First computer mouse 

Over the years of improvement, the computer mouse has changed and in its modern design it has acquired a form that is very convenient for use. The first model was made of wood. Under the body there was a pair of disk-wheels. There was only one button, and the wire was located under the wrist of the person who used the manipulator. 

REFERENCE.By tilting and swinging the manipulator, it was possible to draw straight lines in a vertical and horizontal position.

Basic characteristics

Focusing on the main selection parameters, you will be able to understand which The mouse suits you, therefore, you should not have any difficulties when choosing a new model. You can access the main selection options attribute the following: 

• Type. The quality of the mouse, as well as its convenience and practicality, primarily depend on this parameter. her use. Each person selects an item of use individually for himself and it depends on the purpose. Those users who most often play on a PC will prefer to choose a gaming mouse, because it has additional keys for ease of navigation. For an office user, it will be enough to purchase a laser model, with which it is quite possible to perform a large number of operations. 
• Size and shape. These parameters primarily determine practicality during operation. When choosing, be guided by the size of your palm. Girls for the most part like more compact models, while men are more comfortable working with massive models that are easy to control. 
• Sensitivity. The The parameter determines the accuracy of cursor movement on the monitor. Those users who have work experience, as a rule, attach great importance to this parameter. Besides standard settings, when performing some work, maximum precision may be required, as this may affect the quality of the result obtained. 

REFERENCE. If we consider high-quality branded mice, it is worth noting that their user can adjust their weight.To do this, you need to select a weight, which is ultimately located inside the body. After all, some users like lungs models, others, on the contrary, are more impressed heavy.

• Connection method. Speech coming about wired and wireless models. Here, first of all, it is necessary to focus on for which goals you her choose. If you like to game, it is better to give preference to wired models, they have a faster signal transmission speed. In outbred manipulators, the cursor may lag a little and this can cause various interference. But at the same time they are more convenient and mobile to use. 

REFERENCE. When you use the mouse intensively, as often happens in games, the energy consumption in the batteries increases, and therefore, you will need to replace them more often.
