Computer mice

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

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

Thanks to computer mice, computer skills have become very, easy. Because instead of typing commands and shortcuts on the keyboard, it is enough to hover the cursor over the menu items and the icon and click / double-click on it.

Currently, two types of devices can be distinguished in this respect: wired and wireless mice. We consciously omit Bluetooth and PS / 2 devices as less popular. Both require a USB port on your computer.

Wired mice are powered directly from the computer's USB port and communicate with it via a cable. Meanwhile, wireless mice require an adapter called "dongl" to be connected to the USB port with which they communicate via radio waves.

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

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

Currently, mice use optical sensors (such as small scanners) to count the graphic points of the substrate (mouse pads). The standard working resolution is about 1600 CPI (Count Per Inch) allowing comfortable work on the Full HD screen (1080p)

In addition, we divide computer mice into office, gaming and ergonomic mice. The first are devices for office work, with no "fountains", with two buttons and a scroll wheel. The second are mice usually with a cosmic shape, often with colored backlight, a large number of buttons, dynamically changing resolution and even with additional accessories such as weights and wrist rests.

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