ABSTRACT
In recent years the concept of usability has been broadened from its original concerns with comfort, convenience and ease of use to include notions of pleasure and delight. Specifically these notions of pleasure and delight have been applied to the experience of actual use rather than to that attributed to the ownership or outcome of the use of a product, e.g. the pleasure of listening to music produced by an operated audio system. There is now interest among ergonomists and human factors practitioners concerned with evaluating the usability of products in including criteria which relate to pleasure and its opposite ‘displeasure’ in the experience of using a product.
