Keyboards as Input Devices: A Brief History
The Evolution of Keyboards
The evolution of keyboards can be traced back to the early typewriters, which were developed in the 18th and 19th centuries. The first typewriters were large, clunky machines that were operated by pressing keys that were connected to metal arms called typebars. These typebars struck an ink ribbon to print the characters on the page.
Early Typewriters
The Sholes and Glidden Typewriter, invented by Christopher Sholes and Samuel W. Glidden in 1872, was one of the first practical typewriters. It had 72 keys and used a QWERTY layout, which was designed to slow down the typist to prevent the keys from jamming together as the hammers inside the machine struck the ink ribbon.
The Remington Typewriter, introduced in 1873, was another early typewriter that used a QWERTY layout. It was a popular machine that was used by many writers and businesses.
The First Keyboard
The first keyboard was the keyboard on the Sholes and Glidden Typewriter. It had 72 keys, including letters, numbers, and symbols. The QWERTY layout was used to place commonly used letters far enough apart on the keyboard so that the keys would not collide and jam together as the typebars struck the ink ribbon.
QWERTY Layout
The QWERTY layout is still used on most keyboards today. It places the letters QWERTYUIOP on the top row of the keyboard, and the letters ASDFGHJKL on the bottom row. This layout was designed to slow down the typist to prevent the keys from jamming together as the hammers inside the machine struck the ink ribbon.
Key Legends
The keys on the first keyboards were not labeled with letters or symbols. Instead, they were called “typebars” or “typewheels.” It wasn’t until later that the keys were labeled with letters and symbols, and the term “keyboard” was used to describe the layout of these keys.
