Mieke Brouwer at the University of Twente is researching usability problems that arise in dynamic use situations: when products are used for varying purposes, by varying people and or in varying contexts.

Examples are a mobile phone that is used in varying environments under varying circumstances or a ticket vending machine that is used by many different people with varying skills and expectations.

Brouwer considers scenario-based design as a promising strategy to deal with dynamic use situations, as scenarios allow designers to explore a wide variety of usage situations in an early phase.
