Beyond Usability – Appeal of interactive Products

Usability describes a quality aspect of interactive systems and appliances – so-called interactive products. Usability is broadly accepted as an important and beneficial quality. The user-centered design process as described in ISO 13407 (1999) is more and more applied as a way to achieve usability in product development. So far, various attempts were made to enrich the concept of usability by emphasizing "joy of use" or emotions. In this article a two-component model of perceived product qualities is presented: The first component is of pragmatic quality and refers to task/goal fulfilment, i.e., the usability and utility of a product. The second component is of hedonistic quality and addresses quality attributes with no obvious relation to task/goal-fulfilment, such as "original", "innovative", "exciting", or "exclusive". Both qualities contribute to an overall judgement of the product: its appeal. is the paper discusses how these qualities can be measured, which methods may support the design process and presents various case studies were the consideration of hedonic quality was crucial to the project´s success.
