Abstract. Although i nformation about users is vitally important in inclusive design, its use is often limited. The literature suggests that this is, at least in part, due to the ways in which the information is provided, which do not always match designers' needs. We therefore conducted a study to discover the information formats that designers do and do not like and use. In this paper, we draw implications for the presentation of design information, suggesting that it should be quick and easy to find and use, visual and stimulating, flexible and open-ended, and relate clearly and concretely to design issues. We also propose two categorisations of information formats and types and discuss the suitability of some specific examples of types of user information.
