Abstract: Usability is a well-known area in Human-Computer Interaction (HCI) research. Usability has been the main concept for capturing the “quality of use” of interactive systems which involves the efficiency and effectiveness. On the other hand, in the millennium age, web-based learning becomes an essential educational medium to transfer skills, information and knowledge. The transformation of learning platforms from conventional learning to web-based learning has changed the presentation of the learning documents, whereby from paper-based materials to digital materials on the web. The way information is presented on the printed and web-based documents is different. In web-based documents, the information (content) and the content presentation are both essential and should cooperate with each other in the web-based documents. However, the attention paid to the presentation of information specifically, the readability of the text in web-based learning platform has been limited. Not many studies have addressed this problem where readability is one of the most critical elements in competition with printed material. Thus, for this reason, this study intends to investigate the impacts of visual design of interface on student’s reading text in the web-based learning context. This study took a quantitative research approach that involved experiments to collect the data. The finding of this study found that both types of interface (static interface and dynamic interface) were not able to affect the readability of learning material.
