Abstract

Biofeedback in serious games is becoming increasingly relevant to objectively assessing players’ engagement and performance. This study administered a Matching Pairs (MP) game to a group of healthy volunteers while acquiring eye-tracking data, specifically pupil dilation and blinking behavior. A dedicated algorithm has been implemented for game score assessment. A set of linear and nonlinear features were extracted from physiological signals. Statistical analysis was performed to understand whether oculometric parameters differ between the best and worst MP game trials. Moreover, correlation analysis investigated possible relationships between physiological measures and players’ performance. Results showed statistically significant smaller pupil dilation velocity, higher Index of Pupillary Activity (IPA), and shorter blink rate in the best MP trial than in the worst one. Our outcomes could highlight better cognitive resource management and greater focus in the best trial. Moreover, participants’ scores were negatively correlated with blinking rate and the time the eyes were closed during the game. It showed that more focus on specific game tasks leads to better performance, therefore limiting interruptions of the information flow due to blinking. These findings may suggest that eye parameters in serious gaming platforms could be a powerful tool for intervention programs targeting older populations or people with cognitive impairments.
