Abstract

This paper presents the usability evaluation of a gimmick tracking application designed by students in the Human-Computer Interaction class to solve the problem in one of the biggest food companies in Indonesia. Gimmick tracking is important for the company to make sure the gimmick can be transferred to the customers with minimum-to-none problems. The gimmick tracking application should be user-friendly for the users to make sure the application meets the purpose of its development. Quantitative and qualitative usability evaluation using the system usability scale (SUS) questionnaire and think-aloud method were used to evaluate how effective is the real-time gimmick tracking application. A total of 12 subjects with an age range from 18 to 27 from the grocery stores in Malang were recruited to participate in this study. The SUS questionnaire was used to measure the hypotheses related to learnability, efficiency, memorability, errors, user satisfaction, and usability. The qualitative data such as recorded videos and notes were transcribed into the text for further analysis. The SUS score of the design of the gimmick tracking application was 70.83, this score is higher than 55 percent of other applications. Thus, it can be concluded that our design generally has fulfilled all usability requirements.
