Video Game Telemetry as a Critical Tool in the Study of Complex Skill Learning

This data was used in Thompson et al. (2013).


We aggregated screen movements into screen-fixations using a Salvucci & Goldberg (2000) dispersion-threshold algorithm, and defined Perception Action Cycles (PACs) as fixations with at least one action. Time is recorded in terms of timestamps in the StarCraft 2 replay file. When the game is played on 'faster', 1 real-time second is equivalent to roughly 88.5 timestamps. A list of possible game actions is discussed in Thompson, Blair, Chen, & Henrey (2013). Skip league conditional inference forest classification was used (Bronze-Gold;Silver-Platinum;Gold-Diamond;Platinum-Masters;Diamond-Professional) to show changing patterns of variable importance with skill. Predicted attribute: League (Ordinal)
