Senior-centered design of health information architecture

A series of senior-centered design experiments were used to define the best-fitting web hierarchy for health information for seniors are reported.Three experiments were performed, namely card sorting, category identification and category labeling. The card sorting experiment's results show that senior participants grouped items conceptually on the higher categorization level but were influenced by literal words found in the link names when grouping items at a finer categorizations deeper down the hierarchy. The category identification and category labeling experiments' results suggests the importance of involving users to properly label the link and group names.
