Methodology:
Within this study, consideration has been given to both designer controlled utilities and inherent courseware framework features. The WAI guidelines have been used to develop critieria and a weighting system for scoring.
- Designer Controlled Utilities have been evaluated for accessibility in terms of: Access Support and Information.
- Inherent Courseware Features have been assessed in terms of: Access Support only.
- Courseware Components which are critical to the accessibility of the product have been analysed separately.
Scoring:
- Accessibility: The sum of the scores for the Access Support, Information, and Courseware Components is reported as a raw Total Accessibility Score.
- Functionality: When a feature is supported in a product, its accessibility is analysed, and an addition is made to the functionality score for the product.
- Access Support Functionality Ratio: Because all programs or packages being assessed do not possess the same features, the integrated accessibility score has been related to functionality. The Access Support Functionality Ratio relates accessibility to the overall complexity of the product.
