Description
Effectively measuring the usability of any product requires choosing the right metric, applying it, and effectively using the information
it reveals. Measuring the User Experience provides the first single source of practical information to enable usability professionals
and product developers to do just that. Authors Tullis and Albert organize dozens of metrics into six categories: performance, issues-based,
self-reported, web navigation, derived, and behavioral/physiological. They explore each metric, considering best methods for collecting,
analyzing, and presenting the data. They provide step-by-step guidance for measuring the usability of any type of product using any type
of technology.
Audience
Usability professionals, developers, programmers, information architects, interaction designers, market researchers, and students in an HCI or HFE program.
