Unlike previous publications in usability, which have predominantly concentrated on how to present information, this book focuses on what information should be presented and on information appliances for different cultures. It provides operational tools to effectively prepare the content in a manner that allows users to make good decisions regarding the purchase of goods and services and to obtain information on items of interest. A cross-cultural comparison and fundamental review of the theory, the book not only answers the question of what information needs to be presented for effective decision making, but also addresses the impact of culture on content usability.
