Speaking in front of a real audience is a huge challenge for some people. The goal of this master thesis for one person is to create a VR system that lets you experience talking in front of a large crowd. It should include a 360° recording of a lecture hall or similar setting, the possibility to include your own slides as the presentation shown on the projection, and random events like audience showing up late or leaving, dropping pens, talking, etc. Ideally, it ends with a round of applause at the end. The system is to be implemented and evaluated.
