Proposal and evaluation of webpage menu interface for people with low vision

초록

People with low vision find it difficult to access websites composed of visual contents, which limits them their use of the information provided by such contents. The colorful and inconsistent webpage makes it difficult for them to engage in different activities on the web. To overcome this problem, this study helps design webpage menu interfaces optimized for people with low vision and proposes design rules that can be applied to the existing interfaces. Further, this study proposes vertical and block structure menu interfaces according to the different formats of the hierarchical menu data. To verify the improved usability of the improved menus, the usability evaluation is conducted and compared with the existing websites for evaluation. The evaluation results confirmed that the duration of the task was reduced to half with these two menu interfaces as compared to those with the existing menu interfaces and that the user could understand the hierarchical structure of the websites more quickly and easily while performing the tasks through the block structure menu interface.
