Computer mouse - what is it?

Computer mouse is a very necessary input device, it is convenient to work with it. Not everyone fully understands what it is, how to work with it, and most importantly, what types can be seen on store shelves. Let's deal with these questions.

What it is?

A computer mouse is a manipulator with the help of which the transformation of movements into a control signal occurs. In simple words, the movements that you make with the mouse are converted into signals that the PC perceives and recognizes. For the modern user, this manipulator is an integral part of the computer. If you need to copy documents, select some part of the text, transfer documents from one folder to another, the mouse will become the best assistant.

What it consists of

The manipulator consists of:

• Scroll wheels. With his help, the user has the ability to move information on the screen, scrolling the sheet up or down.
• Keystroke Their purpose: to activate or open objects, their capture and movement.

REFERENCE. Such a device is provided in most models of computer mice.

• On the back is a special sensor. It is necessary in order to read the movement on the surface. Depending on the type of the manipulator, this may be a familiar ball or a laser scanner. It depends on which mouse you use.
• Also, wired mice have a cord with which you connect to a PC. In wireless models there is a compartment where batteries are installed.

Types of computer mice

This device has been modified and improved during its existence. Today it is an easy-to-use mouse that responds instantly to a person’s actions.For various purposes, experts recommend selecting different types of computer mice, because your choice will ultimately depend on ease of use, as well as your result. Some of them are suitable for games, others for work, creating drawings and more. On the shelves of stores you can find these types of computer mice:

• Mechanical. They are now almost no longer used, since there were options with better performance. The tracking sensor is represented by a steel ball, which is rubberized, as well as other elements necessary for correct operation. In the process of moving, the ball scrolls as a result of this, the rollers are pressed to it, the movement is recorded, and then the information is transmitted to the corresponding sensors, which are responsible for the recognition of turn signals. This is how the mouse works with the computer.
• Optical. In this embodiment, a small camera is used, carrying more than a hundred frames in one second in order to read the surface on which the mouse moves. In order to improve the definition quality, a powerful LED is used; it is mounted on the bottom of the device at a small angle. You can see its glow.

• Laser. The principle of operation is very similar to optical devices. An infrared laser diode is used for illumination. This solution improves the accuracy of movement. Work practically on any surfaces is possible.

• Sensory. There are no buttons or scroll wheel. Management is carried out using gestures. This is a new kind of mice, which is very simple and easy to use.

• Induction. Their work is provided by the use of induction energy. When working, you must have a rug, which is something like a worktable.

• Trackball. There are no buttons on them, and for control, an inverted ball is used, from the name of which the mouse has received such an interesting name. This is an unusual model that is rarely found on the shelves. You can buy them either in specialized stores or online stores.

• Gyroscopic. In this model, cursor positioning is possible due to the gyroscope. Reading information occurs both from the surface and from the surrounding space.

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

• Wired. Connect to a PC using USB or PS / 2 wire.
• Wireless. Connection is possible thanks to Bluetooth.

First computer mouse

For many years of improvement, the computer mouse has changed and in its modern version it has acquired a form very convenient for work. The first model was made of wood. Under the case there was a pair of wheels. The button was only one, and the wire was located under the wrist of the person who used the manipulator.

REFERENCE. When tilting and swinging the manipulator, it was possible to draw smooth lines in vertical and horizontal position.

Main characteristics

Focusing on the main parameters of the choice, you can understand which mouse suits you, therefore, you should not have any difficulties when choosing a new model. The main parameters of the selection include the following:

• Type of. Quality of work of a mouse, also convenience and a practicality of its use first of all depends on this parameter. Each person selects the subject of use individually for himself and it depends on the destination. Those users who most often play on the PC will prefer to choose the gaming mouse, because it provides additional keys for easy 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 the practicality of operation. When choosing guided by the size of the palm. Girls for the most part like more compact models, while men are more comfortable to work with massive models that are convenient to manage.
• Sensitivity. This parameter determines the accuracy of the cursor movement on the monitor. Those users who have experience, as a rule, pay great attention to this parameter. In addition to the standard settings in the performance of some work may require maximum accuracy, because it may affect the quality of the result.

REFERENCE. If we consider high-quality branded mice, it is worth noting that their user can adjust by weight. To do this, you need to pick up a sinker, which eventually is located inside the case. After all, some users like light models, others, on the contrary, like heavier ones.

• Connection method. These are wired and wireless models. Here, first of all, you need to be guided by the purpose for which you choose it. If you like to play, it is better to give preference to wired models, they have a faster transmission rate. In mongrel manipulators, the cursor may be slightly delayed and this may cause various interferences. But at the same time they are more convenient and more mobile in operation.

REFERENCE. With intensive work with a mouse, as is often the case in games, energy consumption in batteries or batteries increases, and therefore you will need to replace them more often.
