Applying UX and UI design principles to a commercial project

This thesis focuses on the design of a mobile application called “Tajný agent”, intended to support outdoor escape games. The aim is to create a user-friendly digital solution that offers smooth navigation, intuitive flow, support for team collaboration, and an engaging user experience. The work addresses the shortcomings of currently available applications on the market, particularly in the areas of usability, visual consistency, and support for multiple players across various devices. Methodologically, the thesis is based on the Design Thinking framework and follows its five phases: Empathize, Define, Ideate, Prototype, and Test. The design process includes market analysis, secondary user research, a quantitative questionnaire survey, creation of personas and user scenarios, information architecture design, and iterative prototyping at three fidelity levels (Low-Fidelity, Middle-Fidelity and High-Fidelity). Each prototype is tested with real users through moderated usability testing. The result is a final application design ready for development, whose functionality and usability have been validated through testing with ten respondents from various target groups. The application is evaluated as clear, functional, and visually appealing. The final specification reflects the feedback and includes concrete recommendations for implementation. The outputs of this thesis can be used not only for the actual realization of the “Tajný agent” application, but also as inspiration for creators of digital experiential game applications and providers of gamified solutions in public spaces.
