Abstract
A communication terminal for processing voice and graphical information having a telephone set including a handset supported by a housing with an input device mounted within the housing for establishing communication with a distant terminal. The input device includes a flat display screen having a presentation portion and a switching field portion. A transparent resistive coating which conducts electrical signals and which is mounted over the presentation portion is manually contacted by a pen which extracts a signal for identifying the point of contact. The pen is used to touch the portion of the screen representing a dial keypad and various switching functions. The extracted signals are digitized and transmitted to distant terminals via a control circuit which processes both voice and graphical information.
