ABSTRACT:
An ergonomically developed, dome-shaped, alphanumeric interface apparatus for use with a electronic system, such as a computer or electric typewriter is described. The apparatus is configured in accordance with ergonomic principles and uses chording of both hands to type the characters of any user-defined alphabet. The device includes a set of domes that are shaped and contoured to conform to the shape of hands in a relaxed state and to distribute pressures across the splayed underside of the user's hand. Each dome is capable of movement in a plurality of discrete lateral sectors. The domes used together, utilizing a chording principle, can generate up to 144 characters depending on how many discrete movements are defined by the user. In a nonchording mode of operation, each dome is capable of producing up to 12 characters independently of the other dome. The two-handed implementation disclosed utilizes input movements that enable keystroke actuation via only slight arm or hand movement, no finger movement being required. In addition, cursor control is possible via either dome.
