Interaction Design professionals are constantly seeking to ensure that software and software-enabled products are developed with the end-user's goals in mind, that is, to make them more powerful and enjoyable for people who use them. "About Face 3" ensures that these objectives are met with the utmost ease and efficiency. Alan Cooper (Palo Alto, CA) has spent a decade making high-tech products easier to use and less expensive to build - a practice known as "Interaction Design." Cooper is now the leader in this growing field.
