E-learning’s usability measurement toward students with myopia visual impairment

Abstract

Usability in e-learning is closely related to user interaction, so the e-learning interface needs to be taken into account. In e-learning, the user interface is an important factor of visual interaction between users and learning resources. Related to this, the user’s vision aspect can affect the performance of e-learning usage, especially usability problem, so the study about usability related to user’s vision needs to be done. This study measuring the usability of e-learning using USE Questionnaire and supported by eye-tracking technology. The results were compared between users with visual impairment and users with normal vision. The results obtained are, the usability variables have a correlation with each other. The four variables, which have a correlation to the variable tasks completion by the respondents (Task), are Ease of Learn, Ease of Use, Satisfaction, and Usefulness. This study shows that myopia visual impairment not causing difficulty in task completion. This is demonstrated in relatively similar user interactions, between normal-sighted users and abnormally-sighted users. The tendency to focus on web page elements per task for both groups of respondents are on elements such as announcement lists, course lists, navigation bars, drop-down menus, links and login text-boxes.
