Universal Usability: Designing Computer Interfaces for Diverse Users

Abstract

Jonathan Lazar makes the point, in the preface of this book, that universal usability helps all users. Computer interfaces that include usability features come with a solid business case to support e-commerce spend, as they improve hit rates and support access across a variety of technologies including mobile devices. Universal Usability is a collection of essays covering various aspects of inclusive computing, including a variety of case studies, screenshots, diagrams and photos illustrating good and bad design. After the scene is set in Chapter 1, Chapters 2, 7, 8 and 9 discuss the needs of children, focusing on children with and without learning difficulties. Chapters 3, 10 and 12 cover usability principles for the ageing population. Chapters 4, 5 and 6 present research and projects relating to navigation for blind users. The needs of other user groups, those with amnesia and spinal cord injuries, are discussed in Chapters 11, 13 and 14. Chapters 15 and 16 cover the digital divide and ensuring low-income users have equal access to community and health information. The final two chapters cover case studies relating to ensuring accessibility of US Census information and online texts as part of a digital library. The book concludes with a useful chapter on future usability trends and issues.
