Abstract: Visually impaired (VI) users ‘visualize’ web content by using screen reader. They navigate around the web pages based on their mental model. Unfortunately, blind users can only generate the mental model through audio-mediated experience. In order to have better understanding on their mental model and their navigation behavior, a study was conducted on how VI users interpret web layout in news web sites. In this study, nine VI users were interviewed and their navigation behavior on news web site is discussed. This study revealed that there is strong relationship between VI users’ mental model and their navigation behavior on news web sites that influenced by three important factors such as navigation method, skills with screen reader and their past experiences. The result shows that it is important to involve VI users in the web design phase to minimize web accessibility and usability issues.
