Abstract

Due to the overlapping requirements with people with disabilities, elders can benefit from accessible web design and the use of assistive technologies. But elderlies face also semantic problems that are derived from different perception models or the mere anxiety of using new technologies, which can’t be evaluated by accessibility guideline conformance only. Tackling those semantic issues calls for more user-centered evaluation. The Global Public Inclusive Infrastructure (GPII) provides user interface adaptation based on peoples individual needs and preferences. These preferences are stored in so-called preference sets and can also contain sematic settings. In this paper, we propose an accessibility evaluation method, using the preference sets of the GPII to derive authentic accessibility requirements. Hereby, we’re able to carry out tests according to guideline conformance and semantic requirements. In this context, we propose a personalized accessibility evaluation approach based on original user preferences that addresses the need for a user-centered evaluation.
