Abstract/Summary:
This research examines error detection strategies as a method for ensuring effective World Wide Web accessibility for older adults. It evaluates the underpinnings of web accessibility and their relevance to error detection strategies for the support of older adults. The research provides a contextual definition of computer systems and an account of how error detection relates to accessibility. The Error Detection System strategies focused on developing profiles of the participants. The profiles (self-assessment, testing, observation, and error detection) were used to modify webpages that the participant accessed. This research compares the performance of each profile, using a task list and error collection from the Error Detection System. Different error detection strategies that may be employed are presented, as well as their potential in the development of error detection strategies.
