Experiments with Teleterminals

In the fall of 1976, a series of experiments to explore the uses of a telephone with both voice and data capability was started. This paper describes the evolution, through five different models, ending with an integrated combination of a six button keyset with speakerphone, a full ASCII keyboard, and a 24 line by 80 character CRT display. There are 25 relabelable buttons around the display. Reasons are given for the various arbitrary choices which were made.

SEER, A SEquence Extrapolating Robot

The success of computers in doing routine work formerly done by people suggests that a computer capable of adjusting itself to a changing environment might be desirable. Such a characteristic might be especially valuable to the telephone industry which must service large numbers of people having changing needs and desires. As a step in this direction a relay machine which plays a penny-matching game with human opponents has been built. The machine is described and its behavior against people and other machines discussed.

Computer assisted communication system

This paper describes a continuing series of experiments aimed at providing improved communications for non-vocal, motion-impaired people. Special keyboards, coupled with a computer which permits one or two keystrokes to call out a complete phrase, have been enthusiastically used by children at the United Cerebral Palsy Association in Edison, New Jersey. After a brief review of previous systems, the current one, which uses a stand-alone microcomputer, is described.
