ABSTRACT:
A personal communicating device comprising both a base unit and a remote unit. The base unit is comprised of an alpha-numeric keyboard with recessed keys, a cradle, a super-twist screen, a printer, and an infrared transmitter. The remote unit is comprised of an infrared receiver and a display screen. A user types information on the base unit which is displayed on the base unit's screen. The same information is simultaneously transmitted and displayed by infrared transmission link to the remote unit and displayed on the remote unit's screen. The recessed keys make it physically impossible for the user to strike more than one key at a time while typing with one finger. The cradle allows the base unit to be removably attached to a variety of surfaces including the user's arm or an arm of a wheelchair.
