What is a computer mouse?

A computer mouse is a user (human) interface through which he can communicate in real time with a computer, specifically with its operating system. It is a complement to the keyboard - the basic hardware communication tool.

The popularity of computer mice emerged with the advent of graphical operating systems such as GeOS, Windows, iOS, etc. On 8, 16, 32 and 64-bit computers.

What is a computer mouse used for?

Thanks to computer mice operating a computer has become very, very easy. Instead of typing commands and shortcuts on the keyboard, you can simply move the cursor to the menu item or icon and click / double-click on it.

How to connect the mouse to the computer?

Nowadays we can distinguish between two types of devices: wired and wireless mice. We deliberately left out Bluetooth and PS/2 devices as less popular. Both require a USB port in your computer.

Wired mice are powered directly from your computer's USB port and communicate with it through a cable. Wireless mice, on the other hand, require an adapter called a "dongle" to be plugged into the USB port, and communicate with the computer via radio waves.

The computer "rodent" itself is powered by alkaline batteries, and higher and more advanced models use a built-in rechargeable battery for power.

What are the types of computer mice?

The first models of computer "rodents" were fully mechanical, that is, equipped with a ball that rotated and set in motion the rollers (vertical and horizontal), thus transferring physical movement to the movement of the cursor.

Currently, mice use optical sensors (such small scanners) that count the graphic points of the surface (mouse pad). Standard working resolution is about 1600 CPI (Count Per Inch) enabling comfortable work on Full HD (1080p) screen.

Moreover, we divide computer mice into office, gaming and ergonomic mice. The first ones are office mice with a shape and without "water features", with two buttons and a scrolling wheel. The second are mice usually with a cosmic shape, often with colored backlighting, a large number of buttons, dynamically changing resolution and even with additional accessories such as weights and wrist supports.

Computer mouse and health

The third group are mice that are ergonomic, facilitating everyday work by special (natural) positioning of the hand and wrist. Such pointing devices include vertical mice. Their main task is to enable the user to work with the hand and wrist positioned without any tension or unnatural twists, which prevents potential health problems later on.
