How to choose computer mice

The mouse is one of the most popular computer manipulators, which is explained by its simplicity and ease of use. If you want to purchase such a device, it is quite simple to do this: study the range offered by a specialized mouse store, and then order the goods with delivery. Note, however, that these devices not only differ in size and sensitivity, but they can also have a certain directionality and even have a vertical form factor.

Types of computer mice

If you are interested in a mouse for a PC (personal computer), most models are presented in the following categories:

  • Classic. Devices that do not have a pronounced directionality are meant. They can vary in size and shape, as well as have additional buttons, but in most cases they are suitable for almost any task.
  • Game. This category includes models intended for games. They often have a characteristic “aggressive” design, unusual patterns and colored backlighting. As a rule, certain buttons in such mice are programmable - they can be assigned one or a sequence of certain actions, which is an advantage for most gamers.
  • Vertical. Such a computer mouse has not a traditional horizontal, but a vertical layout. It is believed that such an arrangement of the hand is more comfortable and natural: the load on the joints and ligaments is reduced, which presumably reduces the likelihood of developing specific diseases, in particular, tunnel syndrome.

Mouse to PC connection type

When choosing which mouse to buy for your PC, please note that each type of connection has its own pros and cons:

  • The wireless mouse is more convenient due to the absence of unnecessary wires, but their battery life is limited by the charge of the built-in battery.
  • Wired mice are a versatile option for any situation, but in some cases, a wire can restrict freedom of movement, as well as create some inconvenience, getting confused under your hands.

What else is worth paying attention to

Any mouse has a certain sensitivity, which is referred to as DPI. This parameter reflects the distance the cursor moves depending on the movement of the device itself on the surface. As a rule, it is enough to adjust the optimal sensitivity once at the software level.

If you constantly have to change the DPI value, it is recommended to buy a mouse with a special button for adjusting this parameter. You can find these, for example, in the ITbox online store, where a wide range of products is presented for any requirement.

Safety precautions when working with a computer - the requirements of GOSTs, instructions on labor protection and other documents approved by government agencies. At the enterprise (in the offices), this is monitored by a responsible employee. At home, it is more difficult to organize the safety of using a personal PC: the user either does not know the rules or does not want to follow them.

Let us briefly write down the main factors that negatively affect human health when working with a personal computer:

  • radiation - infrared, electromagnetic, in some cases X-ray;
  • negative effects of screen radiation on vision;
  • damage to posture, fatigue in back (especially in the cervical spine);
  • risk of an emergency.

In our review, we will rely on instructions and rules designed for "industrial" (office) work with a PC. They are informatively comprehensive, so they are suitable for home use.

Using a PC involves three things: start, work itself, and end. Let's talk separately about actions in emergency situations.

Getting Started

Before you start, you should prepare your workplace: the room is ventilated, furniture is adjusted (chair height, backrest tilt, footrests), light is adjusted. It is important to check the integrity of the PC so that there are no visible damage to the monitor, system unit. Damage to cables must not be allowed. Be sure to wipe dust from the monitor, system unit, desktop, additional devices.

The computer turns on in the following sequence: voltage stabilizer (if available), uninterruptible power supply, auxiliary equipment (printer, scanner, etc.), the computer itself (system unit).

You cannot work at the computer if:

  • the monitor is defective (flickering, smudges, image jitter);
  • the wires, sockets or other parts of the PC are damaged.

A responsible employee is called in the office, at home - a master in diagnostics and repair of personal computers. There is no need to “solder the wires” or climb inside the system unit with a screwdriver.
