Case Studies on Biometric Application for Quality-of-Experience Evaluation in Communication

With the popularization of portable terminals, the frequency of application use in the mobile environment increases, and the demand for QoS (Quality of Service) is also increasing. In the mobile environment, the communication fluctuation is large, and the quality requirement for an application that frequently transmits user’s operation to the server side, e.g., a game, becomes severe. QoE (Quality of Experience) has become one of the important topics as a mobile communication ultimate metrics in the academic field as well as in the business field. In this study, we focus on Internet service quality evaluation by biometrics. We aim to analyze the relationship between the quality of the communication service and the biometric signal in a mobile role-playing game situation as a case study. Therefore, we originally build an experimental environment to control delay as a QoS parameter, collect EEG (electroencephalography) and subjective QoE assessment data during game operation, and analyze correlation between the QoE evaluation and the EEG data of gaming. We verify the relationship between the biological signal and QoE in this study.
