The initiative for Web Accessibility (WAI) has defined a set of guidelines for designers concerned with accessibility issues. However, research has shown that these guidelines are insufficient to ensure people with intellectual disabilities have proper internet access. One of the most mentioned problems of web accessibility is related to the difficulty regarding the perception of what is or is not clickable in a web page. This study aimed to investigate the recognition of hyperlinks by people with intellectual disabilities, specifically asking whether hyperlinks in navigation menus are more perceptible with text or with images. The methodology was based on the direct observation, video recording, interview and data obtained by an eye tracker device. Ten participants with intellectual disabilities were divided into 2 groups and asked to perform 2 tasks in 2 websites. The first website presented an image navigation menu (INM), whereas the other one showed a text navigation menu (TNM). The tasks required each group to alternatively interact with the 2 different layouts. The findings clearly showed that images were more comprehensible than text, especially for the participants with reading difficulties.
