Augmented Reality for Immersive Video Conference Presentations : Enhancing Video Presentation Experiences with Visual Aid Through Augmented Reality

Abstract: As 3D models are increasingly used in a variety of contexts, both for entertainment in games and movies, as well as professional visualization and CAD models, there is an increased demand for collaborative tools which can be used to show these virtual artifacts efficiently. Interaction with digital 3D artifacts has long since been enabled through the use of specialized software, like CAD modeling applications and 3D rendering software; which often are extensive and require time to master and use efficiently. This thesis investigates how natural interaction through augmented reality can be used to interact with 3D artifacts in video conferencing scenarios and how it could enrich presentation experiences. Different approaches were evaluated to enable natural interactions before creating a prototype solution. Research was carried out with a design approach by creating a prototype solution, which was evaluated in a user study with a mixed research method. Data were collected through a semistructured interview as well as quantitative methods, which consisted of the NASA Task Load Index and a performance evaluation form filled out by the participants. The interview data were processed with a reflexive thematic analysis, and insight was gained as important themes emerged from the data. The results indicate an increased physical demand, but also less frustration with the prototype solution compared to screen sharing of Windows 3D Viewer. The responses of the study participants highlight key factors to consider in future development.
