Usability User Interface Analysis Using Usability Metric Method on VirCle Application

Abstract

This research aims to analyze the usability of the user interface in the VirCle application using
the usability metric method. Data were collected through observation testing, questionnaires,
and interviews. The research results indicate problems in task success, particularly in the photo
uploading process that requires a description before posting. Although some users exceeded
the predetermined time in the time on task, the overall required time is relatively short. The error
rate is low, only around 4%. The System Usability Scale (SUS) questionnaire results show an
average score of 75, which falls into the "Good" category. The interview results obtained positive
user responses, although some problems were identified. Overall, the VirCle application has
good potential and usability, with some improvements needed, especially regarding photo
description filling and toolbar icons. This research is expected to contribute to application
developers in improving the usability of VirCle and providing a better user experience.
