web accessibility for people with cognitive disabilities
This pilot study investigated individuals with developmental cognitive disabilities (DCD) navigating W3C accessibility-compliant Web sites and the impact of four cognitive determinants: situation awareness, spatial awareness, task-set switching, and anticipated system response . Participants were placed into one of two search conditions and were asked to complete information-finding tasks. The usability evaluation demonstrated that the majority of users with DCD were able to access the Web but they were unable to successfully use the W3C accessibility-compliant Web sites / . The use of navigation aids was examined, different Web navigation problems were identified as well as user satisfaction and perceived usability. It is clear from this study that current Web accessibility guidelines do not sufficiently address the needs of people with cognitive disabilities . Additional research is needed to understand how cognitive disabilities affect using Web-based media.
