Missionor safety-critical domains (e.g. crisis management, healthcare, transportation) are increasingly characterized by interactive and multimedia systems. Therefore, safe and efficient human-computer interaction and cooperation more and more becomes a crucial factor for overall performance, satisfied users and satisfying outcomes. For more than 30 years, usability has been the major criterion for evaluating interactive systems in this regard.
