Browser-Based Game Design for Cognitive Effort Aware Quality of Experience Evaluation

Cognitive effort plays a crucial part in our multimedia consumption experience as it affects attention. However, traditional research in quality of experience (QoE) relies on the subjective ratings of a multimedia consumption experience under a lab-based environment without distractions. To make the collected QoE ratings closer to realistic usage scenarios we designed a browser-based game as an adapted QoE subjective test that can incorporate and quantify cognitive effort using a dual-task paradigm. Our pilot study results show that our proposed browser-based game is a viable protocol that can control for, and reflect, the cognitive effort via selected self-reported measures given an appropriate load range. Future work will further standardise and simplify the game protocol for robustness, repeatability and test duration.
