The purpose of this study was to attempt to create a usable and trustable web application for selling event tickets capable of better satisfying the needs of students and event arrangers at Linköping University than contemporary methods. At the moment of writing all such tickets are sold physically and students are required to queue to acquire tickets. Throughout the study the application was user-tested and metrics regarding readability, navigability, and perceived trustability were tracked. The tests made use of the Concurrent Think Aloud method, the Retrospective Probing method, Smith’s Lostness formula, contrast checking tests, and the LIX readability formula. The test results improved throughout the development process and finally showed that the application could indeed be considered readable, navigable, and in several ways perceived as trusted by its users. The study resulted in an application that with a few modifications, including but not limited to student union discounts and stability concerns, could successfully simplify the vending process for event tickets at Linköping University, or lay a theoretical foundation necessary for future developers to make an application capable of fulfilling either this or similar needs.
