The Basler Fasnacht is a culturally significant event for Basel and its population, which earned it an assignment as intangible cultural heritage by UNESCO. The question arises if conveying the traditions and values associated with the festival can be supported by an AR application. Thus, the need for a research-based approach to developing a MAR prototype for the Fasnacht arises to offer the client a feasibility study and a proof of concept on the prospects of such an application. To achieve this, the presented paper concentrates on creating a functioning MAR prototype for the event.

Interviews with Fasnacht participants are held to extract feelings and opinions about the event and a potential AR app. Based on this, relevant literature is reviewed and analysed to gather themes that constitute the user requirements for the prototype. A House of Quality then identifies and assesses suiting functional requirements. Expert input offers additional guidelines. The prototype is then developed and documented. Use cases further create an overview of the present functionalities. The final system is tested using established and relevant questionnaires to assess its overall success.

The outcome of this work consists of a functioning MAR prototype that enriches users' experience and perception of the Fasnacht. Experiment results indicate that the system fulfils technical requirements and successfully provides users with an enjoyable, entertaining, and educational experience. Additionally, users are motivated to participate in the Fasnacht after using the system and have a high inclination to reuse the application. Therefore, it is assessed that there exists a high potential and general interest in a MAR application for the Basler Fasnacht. It is recommended that further testing is conducted, and additional components and functionalities are developed to enhance the prototype further. Nevertheless, This thesis lays the foundation of a complete AR application for the event. Based on the conducted research and work, a fully developed AR application for the Fasnacht is recommended, using this thesis as a proof of concept. The identified requirements are considered relevant and adequate in creating MAR for the Basler Fasnacht. They are further seen as fulfilled to a high degree in the developed system.
