UI and UX Redesign for COVID-19 Response Mobile Application Using Usability ISO Model and Testing Tools

Abstract

The aim of this study was to analyse the user-friendliness of the COVID-19 Response Mobile Application, namely PeduliLindungi. 107 respondents answered the questionnaire and concluded that the usability of the current version is 68%, which is categorised as ‘terrible' on the system usability scale, indicating that the main concern of users is the accessibility of the application. The main objective is to redesign the UI and UX of the PeduliLindungi mobile application to improve the usability and accessibility of the application. The quantitative method was used as a research tool to obtain the responses of PeduliLindungi users and measure the attributes of the application based on the ISO 9241-11 metrics: Efficiency, Effectiveness and Satisfaction. A revised version of the PeduliLindungi mobile application received a 70% usability rating and was rated "good" on the system usability scale. The study also identified specific usability characteristics from the ISO usability model widely used in usability engineering. A guide was created for developers to include UX considerations in the development of mobile applications
