Computer Keyboard

A computer keyboard is a device used to communicate with a computer. It is set up in the same format as a typewriter. Keys on the keyboard can be used to give the computer commands or to produce letters, numbers or symbols. Computer keyboards may be connected to a computer through either a PS2 connection or USB. Wireless computer keyboards give the user flexibility to move around without having to mess with wires connected to the computer. Generally these types of keyboards communicate with the computer via an IR receiver that is connected to the computer.

Non-traditional Computer Keyboards

A number of non-traditional computer keyboards have been created.

1. With the higher usage of computers, a higher number of cases of repetitive stress injuries has greatly increased. A common solution, which assists in keeping the users hands in a more natural position, is an ergonomic keyboard. This type of keyboard looks much like a normal keyboard, but the key pad is split in the middle, leaving a large space between the two.
2. The roll-up keyboard has been created to allow users to take their keyboard with them. It consists of a keyboard placed in a rubber material, allowing for it to bend easily.
3. A virtual laser keyboard is projected onto a tabletop, allowing the user to type on the virtual keyboard. As the fingers pass through an inferred beam, the computer processes it as a normal keystroke.
