Abstract This article describes one of the first documented participatory design (PD) efforts specifically aimed at older users. The goal of the project was to make an existing World Wide Web (WWW) site more user-friendly for older users, specifically in terms of display format issues. A PD team was assembled from a group of community-dwelling older adults and developers from a university research lab. After the developers established the trust and confidence of the participants and developed a conceptual user model (based on a survey and previous literature), the PD team evaluated the original design. Prototypes were iteratively developed and tested by the PD team to improve problems found in the original design. Specific design improvements and general design guidelines for older WWW users are discussed.
