The development of realtime photorealism in 3D imagery paired with an increasing interest in both TV-series and video games, this project explores ways of adapting photorealistic narratives in realtime, depending on the viewers facial expression. Through an analysis, image processing, branching narratives and realtime rendering technology was explored. A product was created through an iterative development as a proof of concept. This product would detect a user's smile and change the weather in a virtual environment. The product was tested on 34 participants, who were intrigued and generally liked the concept. It was further evaluated by an expert, who confirmed that it served as a proof of concept. In the future the product should be able to detect more facial expressions and adapt the narrative unbeknownst to the viewer. However, further research, development and testing would be needed.
