This paper reports a human factors assessment validation (HFAV) study of the Citarasa analysis system involving the use of scenarios. The scenarios were use descriptions of the system, with embedded Citarasa descriptors, and involved a sequence of actions and events by actors. It is a web-based tool for elicitation and analysis of affective needs developed. Task oriented scenarios were created for two groups of actors: car designers and truck designers. Thirteen OEM vehicle designers validated the system. Each was given two scenarios to perform. To measure usability they completed a 40-item questionnaire. The factor analysis confirmed several important aspects of usability: usefulness, aesthetics satisfaction, perceived control, and task appropriateness. Content validity of items was confirmed with Pearson correlation coefficients. The planners preferred utility of the tool over aesthetics. The scenarios facilitated effective user interaction through enactment of the scenarios during use.
