Every day, HCI professionals work on projects with brand-new requirements and challenges. Now at last is a single source of user-centered design methods that can provide targeted guidance to anyone engaged in designing interactive products and services. Chauncey Wilson has gathered over 100 user-centered design methods, including methods for generating ideas, developing online questionnaires, identifying requirements, developing user interface specifications, inspecting user interfaces, analyzing data, testing products for usability, and more. Each method has been thoroughly researched and tested over the course of the authors 25+ year career in which he has led design teams, taught seminars and workshops, and mentored dozens of students and professionals. The perfect "go to" online reference, the work is highly formatted: each section defines the method, identifies alternative names used in the literature, identifies related methods, provides an overview of the method, outlines the basic procedure, identifies strengths and weaknesses of the method, describes how to implement it, presents variations and extensions of the method, recommends readings and references, and highlights hints and tips in sidebars.
