AR-Schulungs-Anwendung und -Editor für 3D-BIM-Visualisierung im Bauingenieurwesen

The following master's thesis analyzes the visualisation of 3D Building Information Modeling (BIM) data in Augmented Reality (AR) for civil engineering education. Related work, applicable technologies, and relevant standards were analyzed. Based on this knowledge, a framework consisting of a desktop editor and a handheld AR application was designed and implemented utilizing the Unity game engine alongside Google's ARCore. The desktop editor lets lecturers import IFC files, add annotations in the form of images, videos and text to them, and export the resulting projects for the use inside the AR viewer. This development has been supported by members of the Center of Digital Building Process (E234, Faculty of Civil Engineering, TU Wien), who provided real-world requirements and feedback throughout the process. The usability of the two resulting prototypes was evaluated using qualitative and quantitative methods as part of moderated in-person lab sessions. The findings were interpreted and a set of usability problems was identified for each application. Different solutions to these issues were developed alongside implementation ideas and mockups. Lastly, an outlook on the possible future of this project is given.
