Usability of web sites, whatever their type is (e.g., internet, intranet, extranet, supranet) is today widely recognized as a major dimension required for user acceptance and use of web sites. This dimension even becomes more critical for electronic commerce web sites: a customer unsatisfied by poor usability is likely to become a competitor’s customer. Moreover, the user population is expanding in age (ranging from young users to elderly people), in expectations (ranging from private use for leisure to professional use), in information needs (ranging from simple information to compound multimedia resources), in task types (ranging from basic text searches to complex problem-solving methods), and in user abilities (ranging from the able-bodied person to any person with special needs, such as for motor , auditory- or visually-impaired persons). Therefore, web sites should be usable enough to accommodate all these variations over time.
