Abstract. Smartphone with touchscreen usages are becoming more common in <br /> <br /> daily life. These smartphones are also used by people who have disabilities, and <br /> <br /> people with visual impairments are no exception. For this study, visually impaired <br /> <br /> people are those who fit in totally blind category. Three sub-applications from GOJEK <br /> <br /> (GO-RIDE, GO-FOOD, and GO-SEND) and another three from Grab <br /> <br /> (GrabBike, GrabFood, and GrabCourier) were evaluated. These sub-applications <br /> <br /> were chosen by pre-study questionnaire about the blinds’ application priority. This <br /> <br /> study was done to measure usability degree with blind users and to find problematic <br /> <br /> elements in user interface. This study conducted usability testing with mixed <br /> <br /> approach: explanatory sequential design research; Quantitative data measured in <br /> <br /> time, number of errors, Single Ease Question (SEQ) questionnaire score, and <br /> <br /> System Usability Scale (SUS) questionnaire score will be used to evaluate the <br /> <br /> usability level of the application, while finger mapping data and participant <br /> <br /> comments are used to find more specific problems in the design or look for user <br /> <br /> patterns. Main task of this research was to order according to sub-applications <br /> <br /> which being evaluated. It’s concluded that only GO-RIDE has a good usability <br /> <br /> level, and five other sub-applications comes under bad usability degree. Visual <br /> <br /> elements that make usability degree decreased are: touch targets that are too small <br /> <br /> and cluttered in one page, scattered visual elements, and operational Android <br /> <br /> gestures that have not been mastered by users. Usability degree of an application <br /> <br /> could be done by improving the layout or by changing blind users’ navigation <br /> <br /> method.
