ABSTRACT:
A work station for a computer terminal, or the like, comprises a display screen, a work document viewing area, and a keyboard which comply with five physiological functions (a quintad) to reduce the operator's strain. The keyboard and viewing area are angled with respect to the horizontal, and the keyboard comprises two sections angled with respect to each other. The angular excursions in horizontal and vertical directions are thus limited to be within physiological comfort limits. The keyboard is mounted for movement along the face of the screen to minimize the angular difference between the screen and keyboard and to allow the upper limit of the keyboard to become an underscore for any particular portion of the screen. The keyboard provides transverse surfaces for the keys and the space bar, respectively, to reduce strain on an operator's hands by providing for a natural "grasping" motion of the thumb toward the fingers. The two keyboard sections are angled to provide a relatively straight hand-wrist working orientation to reduce strain further. The keyboard is centerpeaked to lessen the amount of hand pronation into the horizontal plane and provides a generally vertical surface facing the operator into which may be incorporated a cursor control unit, other keys, or control devices which similarly allow for operation by the user's thumb in a grasping motion toward the fingers. Each end of the keyboard and the cursor control unit are designed as mnemonic ikons to lessen visual dependence upon these areas. The work document may be viewed directly, with optical magnification, or by electronic projection on the video display screen.
