Abstract
This study redesigned and evaluated the usability of the Android version of the Letterboxd application using the User-Centered Design (UCD) approach. Initial usability testing was conducted using the Cognitive Walkthrough (CW), System Usability Scale (SUS), and User Experience Questionnaire (UEQ) methods. The initial results showed that the Success Rate score averaged 78.9%, the SUS score ranged from poor to awful categories, while the UEQ score was categorized as average. These findings indicate that the system still required improvements in terms of usability.Afterward, a contextual interview stage was conducted, resulting in 50 insights that were mapped into 27 user pain points. The redesign process was then carried out based on Shneiderman’s Eight Golden Rules principles. Evaluation of the redesigned interface showed significant improvements, where the Success Rate score increased to an average of 90.23%, the SUS score improved to the good and excellent categories, and the UEQ score also increased, with all aspects reaching the good and excellent categories. In addition, a Heuristic Evaluation was conducted and identified 17 usability issues. These issues were then used as additional references in the design improvement process. Overall, this study demonstrates that the UCD approach is effective in identifying and resolving usability problems, thereby improving the usability of the Letterboxd application. Keywords : Cognitive Walkthrough, Heuristic Evaluation, Mobile Application, Letterboxd, Sheneiderman Eight Golden Rules, System Usability Scale, User-Centered Design, User Experience Questionnaire
