Abstract

The competitive context in which the number of new audiovisual services increases requires taking user preferences into account to maintain the best possible quality of experience. The aim of the experiment presented in this paper is to study how standardized ITU subjective measures may be supplemented by physiological measurements. Subjective assessments (ITU-T P.920, P.911) and physiological measurements (Blood Volume Pulse, Temperature, Skin Conductance and Eye Tracking) are collected from 34 subjects viewing three different 2D audiovisual contents. Each content was presented under three different quality conditions: a reference one (without degradation) and two degraded ones (audio/video asynchrony or bitrates variations on audio and/or video). Results show an impact of quality variations on the subjective data but not on physiological measures. It might be explained by this first exploratory protocol (degradation, thresholds, content presentation layout, etc.) proposed to study audiovisual quality impact on physiological activity.

结合生理和主观测量来评估视听技术的体验质量

在新的视听服务数量增加的竞争环境中，需要考虑到用户的偏好，以保持尽可能高的体验质量。本文提出的实验目的是研究如何通过生理测量来补充标准化的ITU主观测量。从观看三种不同2D视听内容的34名受试者中收集主观评估(ITU-T P.920, P.911)和生理测量(血容量脉搏、温度、皮肤电导和眼动追踪)。每个内容在三种不同的质量条件下呈现:一种是参考条件(没有退化)，另一种是退化条件(音频/视频异步或音频和/或视频的比特率变化)。结果表明，质量变化对主观数据有影响，但对生理测量没有影响。这可以解释为第一个探索性方案(退化、阈值、内容呈现布局等)提出的研究视听质量对生理活动的影响。
