This video is a sample of elements from my final PhD experiment - the Surveillance Training Serious Game (STSG). This was developed as a proof of concept for the Cognitive Load and Performance Dynamic Difficulty Adjustment (CLP-DDA) system, with an embedded cognitive load measure in the form of a custom virtual detection response task. The final result certainly isn't polished, and we used some free and purchased assets from the Unreal store to help make it, but it was engaging for the players and the CLP-DDA system was successful supporting a positive result for my PhD.
