Practical approaches and examples that incorporate the requirements of older adults into the development lifecycle are particularly useful for web design practice. In this paper, we present a case study of the redesign of a touristic Web portal that presents holiday destinations and supports online hotel booking for older adults. The redesign process involved (a) the identification of a set of 7 principles and 45 guidelines for Web design for older adults; (b) the validation of the identified set with heuristic evaluation; (c) the redesign of the website in a working prototype. The evaluation process compared the existing and the redesigned Web sites through a summative usability test that involved 12 older users and post-hoc interviews and questionnaires. The results showed that the redesigned web site was significantly more usable than the existing one. Finally, we discuss a number of practical issues on the basis of our reflection and experience.
