User Guided Movement Analysis in Games using Semantic Trajectories
summary
A Unity plugin extracts semantic trajectories from raw player paths, groups them with hierarchical clustering using the longest common subsequence, and visualizes results as a transition diagram, dendrogram and selectable 3D path view. The system analyzes movement from about 80 players and is evaluated by 6 industry experts, who successfully localize navigation problems, stuck locations and a distinct group unaware of camera controls. Designers report the transition diagram most useful while some struggle with the dendrogram.
