Abstract: The keys operated by the Middle Fingers in the Second Nearest Row and the Fourth Nearest Row of the Alpha-Numeric Core, i.e. QWERTY D K 3 and 8, and the center key on the Number Pad are provided with hand positioning structures.Hand positioning with the Middle Fingers is based on the anatomical structure and bio-mechanical functioning of the arms, wrists, hands and fingers, and the hand positioning structures function by the neuro-sensory process of 2-point discrimination.With minimal practice, use of the hand positioning structures quickly functions at a subconscious reflex level.The hand positioning structures enable the operator to maintain visual focus and concentration on the text or display screen, and thereby eliminates unnecessary eye movement and text-reading errors due to eye movement.The structures and methods enable eliminating Home Row, and thereby eliminates awkward movements and contortions and eliminates the errors resulting from awkward movements and contortions.

Abstract: An improved keyboard for computer terminals, computer input devices, word processors, typewriters and any other operating or simulator keyboard is disclosed in which selected keys of the keyboard are selectively positioned and aligned to enable a proper alignment of the left forearm and left hand from elbow to fingertips for the keys that are operated by the left hand, and to enable fast, accurate, unobstructed and comfortable movement of the fingers of the left hand; and in which selected keys of the keyboard are selectively positioned and aligned to enable a proper alignment of the right forearm and right hand from elbow to fingertips for the keys that are operated by the right hand and to enable fast, accurate, unobstructed and comfortable movement of the fingers of the right hand. The improved keyboard also provides a tactile and visual means for placing the hands in proper positions on the keyboard.
