PENGALAMAN INTERAKSI TUNANETRA PENGGUNA APLIKASI ANDROID GO-JEK DAN GRAB

Abstract

This study on the interactional experience of people who have visual impairments or disabilities in using Go-jek and GrabAndroid applications employs usability testing using mixed approach. It is an explanatory sequential design research;quantitative data were measured in time, number of errors, Single Ease Question (SEQ) questionnaire score and SystemUsability Scale (SUS) score. They were used to evaluate the usability level of the application, and finger mapping dataand participant comments were used to find more specific problems in the design or look for user patterns. Usabilityevaluation was carried out on 6 sub-applications from Go-jek and Grab companies. Good grouping of visual elementsand the completion of a small task makes usability perceptions increase. Yet, the design problems that make usabilityperception decrease are touch targets that are too small in size, bad visual element grouping, too many items in one page, and unfamiliar operational gestures. This research has also found that high usability score is not always determinedby visual elements. Navigation behavior has an important role in making good usability perception in users with visualimpairment. A problematic visual design could be considered a problem in one navigation method, but not in another.
