Usability Evaluation Methods of Mobile Applications: A Systematic Literature Review

At this time, mobile devices have an important role because it provides changes for users. Not only making calls, but many features and applications are used to make work easier. Mobile application development brings new challenges to mobile devices, such as usability context when users use mobile applications. Usability is an important factor in mobile applications' role in making them easy to use and efficient. User Interface (UI) and User Experience (UX) has a critical role in software development. It has a function that is one of the keys to the effectiveness of using the software. This study aims to find popular usability evaluation on mobile applications with the help of a Systematic Literature Review (SLR). The usability evaluation process of mobile applications is carried out with a systematic literature review of 22 papers. The results show that 73% of the methods used are usability testing, 23% heuristic evaluations, and 4% are user satisfaction usability evaluations. To conduct usability evaluation on mobile applications, usability testing is carried out in five stages, involves participants, and has the characteristics of Effectiveness, Efficiency, and User Satisfaction. Meanwhile, in heuristic evaluation, experts must be involved in evaluating the user interfaces. This study proposes a mixed method of usability testing and heuristic evaluation in conducting usability evaluation on mobile applications. This method is expected to provide effective and objective usability issues from the perspective of users and experts in improving User Interface (UI) and User Experience (UX).
