“Usability is an approved quality when designing interactive products. Another factor becomes more and more important: the hedonic quality, which includes the aesthetic of a product. The long-time experiences in user-friendly design convinced the initiators of Beauty matters that the combination of usability and aesthetics ensures the success of a product. Usability alone ist not enough. Most people associate the aesthetics of a product with its beauty. The beauty is also decisive whether a product represents a special value for us.” (Michael Burmester, Marc Hassenzahl and Franz Koller)
