Mechanical typewriters have sunk into oblivion, the crackling of which personified high technology and the possibility of obtaining a high-quality readable text.
The keyboard, or keyboard, has replaced bulky devices with hammers. However, it has undergone significant changes over the past 15 years.
The gadget is used with:

Ergonomics is the science of the interaction of a person with his working environment, the ability to make conditions as comfortable as possible, using the disciplines of psychology, physiology and technology.
For the convenience of working with two hands, preventing muscle fatigue of the hands and the ability to spend a long time at the keyboard, the developers of the world's leading brands have introduced a number of innovations in the design of the keyboard.
Simultaneous work with both hands imposes a certain load not only on the user's attention, but also on his wrist joints and muscles. With long work, tense hands begin to get tired, fingers can make erroneous clicks, become numb.
To eliminate discomfort, the panel was divided into 2 parts with a certain set of keys, which significantly increased comfort and ease of manipulation. The angle of the parts relative to each other is 120°.
A model divided into two separate blocks is called a composite model and allows the user to place the parts in any position:
This design has a high price and is especially revered by gamers.
A certain part of the keys intentionally has a larger size than the rest. This is due to the frequency of their use. An experienced user does not look at the keyboard field, works on "muscle memory", so the increased size of "popular surfaces" significantly speeds up the overall process and guarantees protection from fatigue.
It is this anatomical part of the hand, like the wrist, that is subject to greater stress during work, as it is, as a rule, in a hanging state. A special stand relaxes the area of the hand and transfers the saved resources to finger activity.
The keystroke principle used in the device divides the entire range of gadgets into several types.
The most common mechanism, which is quite cheap to implement.
The contacts of the internal printed circuit board are closed by pressing through the membrane, which, due to its convexity, subsequently returns to its original state.
The main disadvantage with strong temporary loads is the wear of the membranes, which entails fuzzy pressing and subsidence.
The advantages of this type can be safely attributed to the silence of work and compactness.
Membrane circuitry enhanced with two scissor-like cross loops under the button. The task of the loops is to return the button to the status quo after pressing the dome of the membrane. A light touch on the key provides quick contact and uniform typing, which increases the speed of the process. The principle is most often used for a laptop, has a long warranty, high cost and silent operation.
The principle of operation is based on:
Models are more adapted for fast printing and require less effort.
The switch, in turn, also has several subclasses:
The mechanical type is easy to clean from dust and debris, you can replace the keys, they will last much longer than their counterparts. Their price is higher and is not always associated with light weight and compactness, but rather the opposite - the model can be heavy, bulky, noisy.
Having decided on the mechanism of the device and its design, it is necessary to take into account a number of additional requirements.
The method of connecting the device to the device can be divided into:
Wired connection schemes mostly work via USB. A well-known connector that is a thing of the past is PS / 2, which is relevant for models with a limited number of USB ports. In this case, an adapter can come to the rescue.
Advantage of wired connection:
Wireless circuits are versatile in their many ways of connecting to many devices. A Bluetooth adapter is used to connect to a PC. The cost of wireless models is higher, but some of the problems in the form of an abundance of wires are automatically removed.
Connecting via a radio channel provides a wide range that exceeds the Bluetooth zone. Such a circuit requires a separate slot, and may be subject to noise and interference from home appliances.
The best option is a combined connection channel with different connectors.
With a serious approach to the choice, you should pay attention to the backlight, tightness and brush stand.
For lovers of round-the-clock operation, this feature is necessary.
The backlight function is also appreciated by visually impaired users.
Illumination is divided into:
In some models, it is possible to change colors and options for highlighting the keys. The most common feature for gaming devices.
The gadget is equipped with a built-in sound card or has a connection to the sound outputs of a PC.
Several USB inputs, combined into one, for working with a flash drive, mouse and a number of other devices.
An integrated touch pad is installed to replace the use of a mouse.
Prudent developers took into account cases of liquid getting on the keyboard.
For such protection, both drainage holes and sealed enclosures are used.
Additional keys have a specific purpose and are used when the desktop is inaccessible, for example, in a game or when watching a video. Keys can be customized and assigned a purpose.
The audio player buttons adjust the volume, work to restart and stop, and also allow you to select a track.
Application launch keys are implemented as convenient activations of the calculator, player, Excel, Word, Explorer.
You can use the button to start sleep mode or turn off the computer.
Experts are of the opinion that there should be no more than 5 additional buttons. Otherwise, there is a clutter of the area and, as a result, inconvenience.
The software and memory make it possible to program the keys for the necessary commands, as well as save the specified backlight characteristics.
Profile editing and saving is provided by the software. More than one profile is reserved for multiple games. Quantity plays a positive role in this case.It's good if the software comes on a disk upon purchase, or is freely available on the company's website.
Muscle memory develops habituation to a certain layout - ANSI or ISO.
It is easy to distinguish the model by the appearance of the Enter button. Its vertical arrangement and the reverse arrangement of the Russian letter Г refers to ANSI, the horizontal Enter has ISO. It is advisable not to change the layout and use the one to which the habit has already been developed.
The most common case when buying a multifunctional keyboard is not using some of the features due to uselessness or ignorance.
An ergonomic keyboard is a complex device, it would be wise to learn the devices step by step and not spend money on unlearned features.
The ergonomics of the keyboard in all its manifestations finds its fans according to different principles. Some require backlighting, others focus on the wrist rest, and others need the number of additional features.
You can conditionally divide all devices into general-purpose and gaming devices.
The device belongs to the membrane type and has a Bluetooth connection.
Recognized as the flagship among ergonomic keyboards, it features a curved base and a split palm rest.
The gadget is sold complete with a mouse and is marked by special attention of buyers as the owner of a unique design and low noise level.
The membrane-type wireless device has 16 additional keys.
The curved shape of the keyboard with a convenient arrangement of keys brought the device to a leading position among ergonomic devices.

Gamers value devices for such advantages as:
In mechanical devices, the most common are:
The design provides an indicator of response time, sound, tactility. Experts opt for the German brand Cherry MX, and recommend boldly purchasing keyboards with such switches.
The wired popular model from the gaming series belongs to the membrane type.
The gaming device of the budget class is made on the Outemu Blue mechanical solution.

Thanks to high technologies and bold decisions of developers, the keyboard has turned into an independent multifunctional gadget with many possibilities.Having useful information and clearly realizing the purpose of the device, you can make a worthy choice and save money.
The market is dominated by wired models, benefiting from cost, weight, lack of batteries and good reception and transmission.
For gaming keyboards, it is important to programmatically reconfigure the assignment of keys, bind macros to them and block unnecessary buttons.
