User experience is conceptualized as a phenomenon consisting of instrumental and non-instrumental quality perceptions as well as emotional user reactions. Visual aesthetics is defined as one non-instrumental quality and available methods are applied to measure the perception of visual aesthetics of interactive systems.

The results show that usability and visual aesthetics can be perceived independently.
