Description

ToTCompute is a mechanism that automatically computes TimeOnTask threshold values for various game tasks using game-playing logs and EEG engagement data collected during an initial testing session. It computes "the relative engagement changes for all participants every second (i.e., every TimeOnTask iteration)" and applies a time series linear model with an autocorrelation test, returning NA when data is random or the trend is not negative. Thresholds represent upper limits above which engagement decreases by a predefined relative change (e.g., 5, 10, 15%).

Accounts

• ToTCompute mechanism for automatic computation of task-dependent TimeOnTask engagement thresholds: ToTCompute is a mechanism that automatically computes TimeOnTask threshold values for various game tasks using game-playing logs and EEG engagement data collected during an initial testing session. It computes "the relative engagement changes for all participants every second (i.e., every TimeOnTask iteration)" and applies a time series linear model with an autocorrelation test, returning NA when data is random or the trend is not negative. Thresholds represent upper limits above which engagement decreases by a predefined relative change (e.g., 5, 10, 15%). (Ghergulescu et al. (2016))

Claims

• TimeOnTask threshold values computed by ToTCompute explain up to 76.2% of the variance in engagement change [+W]
• TimeOnTask threshold values are highly task-dependent, making manual setting laborious [+W]

Related Research Methods

• Non-disturbing engagement monitoring via game-play interaction logging and physiological sensing
