ABSTRACT

Despite the availability of usability, accessibility and acceptance guidelines designers and developers do not user-test or adhere to the guidelines often enough to ensure usable, accessible and pleasurable products for all users. By identifying the synergy and/or autonomy of accessibility, usability and acceptance issues and the most relevant aspects for quality design, more effective and efficient evaluation methods are possible, encouraging greater user guideline compliance. Usability and accessibility are becoming an expectation rather than an exception, partly because of greater consumer awareness and legislation such as the Disability Discrimination Act in the UK and similar legislation in other countries. Many guidelines focus specifically on either accessibility or usability rather than evaluating both simultaneously, making them less efficient. In addition, the focus in evaluation is often placed on particular group of users, potentially excluding other groups. Order of evaluation was counter balanced and each site was assessed by two participants who had little or no previous exposure to that particular site.
