Enabling Metaphor Evolution for Improving Systems' Usability‪.‬

ABSTRACT: In this paper we consider both the interface language and domain language of a software system. That system co-evolves with its user group, with its usage context, application domain, and usage conditions. We presuppose that the evolution of that system is triggered by and reflected in the use of those languages. Since human language use is essentially metaphorical we expect the metaphors employed by system users to evolve when the software system evolves. To assure maximum usability of that system we suggest using a signal interception and pattern substitution component for implementing a controlled change of the metaphors that are available in the mentioned languages. We show how our prototype of such a component can be used for implementing the evolution of the used metaphors. Our approach focuses on the maintainability of the metaphors rather than on a once-and-for-all method for optimally choosing them. Categories and Subject Descriptors
