Thermodynamics Reloaded: Experiencing Heating, Ventilation and Air Conditioning in AR

Augmented Reality (AR) has great potential for new didactic concepts in teaching. Environments, information and objects can be comprehensively and dynamically represented, supporting self-paced and holistic learning. This paper presents an implementation of a multimodal AR-application for the purpose of teaching complex features and mechanics of a ”Heating, Ventilation and Air Conditioning System” in a situated and engaging way. The application was designed and implemented by an interdisciplinary team and evaluated in a mixed-methods approach. Results show a high usability and acceptance of the application. Students recognized the benefit of the application regarding their motivation and learning gains and made suggestions for further improvements.
