Abstract: | This paper addresses user modelling for “Design for All” in a model-based approach to Human-Computer Interaction, paying particular
attention to placing user models within organisational role- and task-related contexts. After reviewing a variety of user
modelling approaches, and deriving requirements for user modelling related to Design for All, the paper proposes a role-driven
individualised approach. Such an approach is based on a model-based representation schema and a unifying notation that keeps
the user’s models and the contextual information transparent and consistent. Individualisation is achieved by coupling symbolic
model specifications with neural networking on synchronisation links between symbolic representation elements. As a result,
user modelling for Design for All is achieved not by stereotypical user properties and functional roles, but by accommodating
the actual users’ behaviour.
