摘要

As part of the OPTIMOS 2.0 funding project of the German Federal Ministry for Economic Affairs and Energy (BMWi), a partner develops the Tick-etIssuance app for secure hardware-based storage of high-priced tickets. The app has implemented a previously unknown technology using the Secure Element and the NFC interface. It is therefore imperative to investigate the usability of the app for a successful market launch. For this purpose, user tests of a prototype of the app were conducted using the think-aloud method. This study analyses the results of five tasks. Test subjects rate the expected and perceived difficulty level for each task. That forms the basis for identifying improvement strategies. The test subjects' performance, the frequency of errors and problems encountered, and the need for moderator's support form the basis for prioritizing usability items within the tasks. The developed structure to determine the test tasks' prioritization and usability items, layout, navigation, handling, wording, system, and data economy offers improvements to increase usability. Furthermore, the study investigates the determination of a suitable sample size for usability testing.
