Abstract
A keyboard to be used on an operators lap that separates to relieve stress in an operators neck and wrists. The keyboard has a flat surface between the keyboard sides, so while being held on a persons lap, will hold reference material and a second party pointing device that can be used with either hand to keep the neck straight. A separable keyboard that is only electrically connected, so each side of the keyboard can be operated on completely different surfaces. A notebook computer with keyboards that open up on each side so the operators hands are separated. The keyboards can slide closed or fold closed, and when folded, interleave so full size keys can be used and facilitate a more compact design, and can be unfolded so the keyboards slant down below the computer to centralize the computer on a persons lap, and reduce the twist between the hand and wrist. The keyboard includes a means to turn all visual indication of computer operation off to be used in a secure no light area with a speaker to give verbal enunciated messages in response to the keyboard and from a computer.
