The evaluation of interactive adaptive systems is considered as a difficult endeavour due to the complex nature of these systems. Issues arise in the need to identify, for a given evaluation situation the set of suitable usability evaluation methods to be used by the evaluators. This paper describes a framework for supporting the choice of appropriate methods for the usability evaluation of interactive adaptive systems. It is based on the comparison of usability evaluation methods using relevant criteria. This framework is then validated through a case study; it concerns an adaptive hypermedia system in transportation field.
