Subjective self-assessment is a frequently used method when it comes to Quality of Experience assessment in general. If correctly used, a variety of scales can be applied to assess the quality of cloud gaming for different constructs such as experienced quality or flow. Besides self-assessment, physiological correlates are a promising method to measure the influence of cloud gaming quality on the player without the interruption introduced by the rating task.
In this talk, subjective and physiological results and lessons learned from a laboratory study are presented in which 32 participants played a first-person shooter game in a cloud gaming setup with varying levels of video quality caused by different video compression bitrates. It was found that the video quality significantly influenced the perceived quality, player experience and performance, valence and wakefulness ratings and, with some limitations, the alpha frequency band power.
