A Method for Generating Messages of the Interactive Software Based on the Individual User Model

Abstract

AbstractStudies have been made on computer systems based on the user model reflecting the behavior of the users, aiming at the human interface which is easy to use. Recently, it has been proposed that individual models be constructed for the users, rather than a model where the only one “typical” human model represents the user in general. A case has not been observed, however, where the individual model is utilized fully in the interactive computer system which actually requires such an approach. From such a viewpoint, this paper proposes a generation of suitable messages utilizing the individual user model, by restricting the problem to the generation of the messages from the computer side in the construction of a program in the interactive programming environment. The features of the user model which will be useful in such a problem, are pointed out. The points in this study are that the skill of the user concerning the system is separated into the general understanding level and the knowledge of the individual functions; utilization of the information obtained by the operating system and for the language processor; and object‐oriented user model whose contents are always updated. A human interface was implemented experimentally which indicates the individual user, the error message from Lisp interpreter according to each situation. We have conducted an experiment by using the interface. The usefulness of our method was demonstrated by the result of experiment.
