在本章中，我们描述了用户如何感知影响QoE的用户、系统和使用环境因素。为此，我们使用特征的概念，即体验的可感知、可识别和可命名的特征。这样的特征可以看作是感知空间的一个维度，我们将分析这个空间的性质和维度。然后，我们将回顾通过经验方法为几个多媒体服务提取的特征，并将它们分组在几个级别上。对于两种示例性业务（语音传输和视频流/通信），我们将更详细地描述其特征和相应的方法。最后，我们讨论了影响因素与质量特征之间的联系，并确定了研究的开放性问题。
In this chapter we describe how the factors of the user, system and context of use, which influence QoE, are perceived by the user. For this purpose, we use the notion of a feature, i.e., a perceivable, recognized and nameable characteristic of an experience. Such a feature can be considered as a dimension of the perceptual space, and we will analyze the nature and dimensionality of this space. We will then review features which have been extracted via empirical methods for several multimedia services and group them on several levels. For two exemplary services (speech transmission and video streaming/communication), we will describe the features and corresponding methods in more detail. We conclude by discussing the links between influence factors and quality features, and by identifying open issues of research.
