“…Considering the duration of the actual playing per scenario (three minutes in the first study, five minutes in the second), it is possible that longer gaming sessions would have allowed for better conclusions from the data as player experience features such as flow and immersion might need more time than was available. Physiological measures such as Electroencephalography (EEG) are promising means to elicit perceived quality without the interruptions caused by questionnaires and have already successfully been used to estimate the cognitive state of test participants [1].…”

In this paper, we investigate factors influencing the Quality of Experience (QoE) of mobile gaming. More precisely, we assess the impact of the type of game, the display size, and network delay on different perceptual dimensions of gaming QoE. Results show that display size has a considerable impact on both overall quality as well as four out of seven player experience dimensions. For delay, the impact is more heterogeneous than screen size, as it depends on how network latency impacts game rules and visual rendering. Conclusions are drawn with respect to the question how experiments addressing gaming QoE should be set up to obtain generalizable and reliable results.

“…In related studies, a decrease in speech stimulus quality was associated with an increase in sleepiness. This effect was measured by changes in the α band in response to speech stimuli of long duration (audio books) in constant [24] and varying quality conditions [25]. Arndt et al [26] studied the QoE of text-tospeech systems.…”

Abstract-We present a survey of psychophysiology-based assessment for Quality of Experience (QoE) in advanced multimedia technologies. We provide a classification of methods relevant to QoE and describe related psychological processes, experimental design considerations, and signal analysis techniques. We summarise multimodal techniques and discuss several important aspects of psychophysiology-based QoE assessment, including the synergies with psychophysical assessment and the need for standardised experimental design. This survey is not considered to be exhaustive but serves as a guideline for those interested to further explore this emerging field of research.

“…These effects reflect emotional processing and fatigue, respectively [97,98]. Rapid, short-term (phasic) changes in neuroelectric activity time-locked to the onset of a defined stimulus event manifest in the EEG signal as a specific sequence of event-related potential components.…”

Speech communication services have been amongst the first telecommunication services to be used by a wide public, and the quality experienced by their users has been an object of concern since then. Methods on how to evaluate quality using test participants or using technical measurements and algorithms have been standardized mostly in Study Group 12 of the International Telecommunication Union (ITU-T SG12) and the Technical Committee Speech and multimedia Transmission Quality (STQ) of the European Telecommunications Standards Institute, ETSI. This paper reviews new and updated ITU-T Recommendations and ETSI documents which have emerged within the last 12 years, and puts them into the general framework of available standards for this type of service. It also discusses current work items of ITU-T SG12 to illustrate directions of thoughts and future Recommendations to be addressed within the next study period.
