Conducted as a research study, this doc presents an approach for predicting users' level of engagement from visual cues within a game environment. We use a large data corpus collected from 58 participants playing the popular platform game Super Mario Bros. Neuroevolution preference learning and data mining techniques is used to construct accurate models of player experience that approximate the relationship between extracted features and reported engagement. The results obtained show that highly accurate models can be constructed (with accuracies up to 96.82%) and that players' visual behaviour towards the end of the game is the best for predicting engagement.
The resulted paper (not this doc) is published in UMAP 14, named: "Utilising Visual Features as Indicators of Players Engagement in Super Mario Bros".
