Premium laptops still use keys that offer resistance while pressing them. In most laptops, the number keys (found on the right side of the desktop keyboard) are not included, and multiple combinations of keys are used to type individual symbols or perform certain tasks. Unlike desktop keyboards, they condense multiple characters into fewer buttons to save space and make for a smaller product. Laptop keyboards take on a flat layout attached to the bottom of the monitor and feature various configurations of alphanumeric characters and symbols. The premium models allow users to customize the binds of keys or even use macros to perform tasks quickly. The number pad at the right of the letter keys is helpful in ten-key and data entry operations.Įxtra keys translate to more functionality, especially when referring to brands like Razer, SteelSeries, and Logitech. Most of these keyboards are at least 16 inches wide and about 6 inches (or more) deep. ![]() They are quite similar to electric-typewriter keyboards but feature some additional keys like Windows key or command keys. Full-sized / Desktop Keyboardįull-sized keyboards include alphabetic characters (usually arranged in the QWERTY configuration), numbers, punctuation marks, typographical symbols, currency symbols, function keys, and special characters. Chorded keyboards have now been completely replaced by more advanced multi-functional keyboards. However, in the last four decades, the trend has shifted from task-specific to more general applications. Yields fewer errors than QWERTY keyboards.Their popularity reached a peak in the 1970s when IBM launched two- and three-chord keying devices to rival the typewriter. This type of keyboard became popular as a data entry input device in the mid-1950s. For instance, a keyboard with only 6 keys allows you to enter a total of 63 (2 6 – 1) different chord combinations. It’s quite similar to playing a “chord” on a piano.Ī large number of combinations allows you to enter text or commands with one hand. Chorded KeyboardĪ small chorded keyboard about the size of a numeric keypadĬhorded keyboards contain only a few keys that generate a letter or word based on the combination of keys pressed at the same time. Modern keyboard designs utilize hybrids of various technologies to achieve better ergonomics and higher cost savings.īelow, we have presented several different types of computer keyboards that have been designed over the past few decades to make human-computer interaction more effective. In order to simulate the experience of physical switches, virtual keyboards (on touchscreen screens) provide audio and haptic feedback. These devices have adapted optional, touchscreen-based means of data entry. Even with the advent of mobile personal computing devices, such as smartphones and tablets, keyboards remain central to human-computer interaction. Keyboards have been the primary input method for computers since the 1970s, supplemented by a handled-pointing device (mouse) since the 1980s. They also contain special keys like Tab, Alt, Shift keys that perform unique functions. Alphanumeric keyboards, for instance, have 80 to 100 durable switches, generally one for each key. It allows users to give commands via multiple buttons. A keyboard is the most basic way for users to communicate with computers or other electronic machines. ![]()
