Designing Pleasurable Products [PDF ebook] 
An Introduction to the New Human Factors

Written by Patrick W. Jordan, a leader in cognitive ergonomics, this landmark resource not only explores usability, but takes the reader beyond it. The author explains how good designs can appeal to the user holistically, leading to products that are a joy to own and use. He examines how human factors are being used more and more in the product design process within commercial manufacturing organizations. The book delineates a practical framework, providing a structured approach to the creation of product design concepts, describes new design and evaluation techniques and established methodologies, such as Kansei Engineering, and includes a pre-validated questionnaire for evaluating designs.
