ABSTRACT:
In a user-interactive display-based telephone system, the present invention permits an automatic display of a repertoire of telephone command items most likely to be utilized by a user, thus providing one-touch access to such item without requiring either explicit programming of a command repertoire or a search by the user through the history of previous commands. This is accomplished through the use of three heuristics which consider frequency of command use, recency of command use, and previously failed commands. These heuristics may be implemented either separately or together in the system.
