2 - The usability of digital information environments: planning, design and assessment

Abstract

The proliferation of Internet-based digital resources has increased the need for well designed digital information environments. Competition is fierce as users rapidly ‘surf the web’ in search of information, entertainment and social connection. Twenty-first-century information-seekers have little patience for confusing interfaces, poor use of media, or sites that are difficult to navigate and understand. This chapter explores and defines the concept of usability and establishes its place and value in designing digital environments for use with the technology devices used to access them. It examines the body of research on information and information-seeking behaviour followed by a set of guidelines for designing digital information spaces for both adults and youth. Lastly, assessment and evaluation are discussed as essential aspects of the design and continuous improvement foundation for any highly usable system. Readers will be provided with a set of applicable guidelines in which to design, implement and evaluate highly usable digital environments within the context of a sound theoretical framework.
