The invention of widely used modern keyboards can be traced to the invention of the typewriter machine. Most of us have already aware of this mechanical machine which was being used to write any document. Whereas some places of the world are still using typewriter machines as per their preference.
The invention of modern computer keyboards has not happened in one day. It was a gradual process of its evolution. The first computer keyboards were adapted from the punch card and also from the teletype machine. Punch cards, also known as Hollerith cards or IBM cards, are paper cards where multiple holes may be punched by using a hand or machine to represent computer instructions and its data. This keypunch or punch card soon evolved to include keys for text and numeric values similar to a normal typewriter by the 1930s.
In 1948, the Binac Computer was developed by John Presper Eckert, Jr. and John William Mauchly under a contract with the Northrop Aircraft Corporation. The Binac computer had a typewriter-keyboard unit. This keyboard unit had eight keys representing the octal numbers and was used to input either the program or data into the computer and memory.
In 1954 at “Massachusetts Institute of Technology” (MIT), researchers begin experimenting with direct keyboard input to computers. And in 1955 MITs Whirlwind becomes the world’s first computer that was using a keyboard where users can feed commands directly to the computer to perform their functions. This was the brief journey of modern keyboards. But as we know human beings are always trying to improve the running technique. At present time a new kind of keyboard had been introduced in the market a few years ago. And it is Virtual Laser Keyboard. Sounds good! So let us find more about this gadget.
