ABSTRACT:
A keyboard arrangement for reducing stress and tension experienced by a human operator during communication with an information processing machine. The keyboard, which may have the actuators thereon arranged in a conventional keyboard distribution, such as a QWERTY keyboard system, is splitable into first and second sections, each such section containing respective portions of the actuators. When joined, the two keyboard sections form a unitary keyboard which is conventional in appearance and operation. When separated, a display screen may be interposed between the keyboard sections, and the keyboard sections may be arranged in selectable spatial positions and orientations selected for the comfort of the operator. An adjustable mechanical mounting arrangement is provided for ensuring positional stability of the keyboard sections. In a further embodiment, an information processing system is arranged to be portable in a housing which permits the screen to assume a sloped position. When not in use, the keyboard sections may be stored in a compartment beneath the display screen.
