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 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 or keyboard to centralize the computer on a persons lap, and reduce the twist between the hand and wrist. The keyboard includes a device 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.

Abstract: A keyboard where no finger pressure is needed to input data, that uses rows of emitters opposed by rows of detectors to detect a finger position, that is environmentally sealed, and inherently intrinsic safe. The keyboard has a mouse function so an operators finger can be tracked to position a cursor on a host display, and input normal keyboard functions. A sleep mode for a display or keyboard that slows down the scan rate and emitter intensity to increase emitter life. A split keyboard for each hand with an arm rest with an arm strap to attach the keyboard to an operators arm and a strap to attach the keyboard to the arm of a chair. A learning keyboard with a mode for QWERTY or other key pattern keyboards that the position of the operators fingers are tracked and supper imposed on a display, so the operator can see when their finger is over the correct keyboard indicia so correct data entry can be made without looking at the keyboard.
