With the coming of age of virtual/augmented reality and interactive media, numerous definitions, frameworks, and models of immersion have emerged across different fields ranging from computer graphics to literary works. Immersion is oftentimes used interchangeably with presence as both concepts are closely related. However, there are noticeable interdisciplinary differences regarding definitions, scope, and constituents that are required to be addressed so that a coherent understanding of the concepts can be achieved. Such consensus is vital for paving the directionality of the future of immersive media experiences (IMEx) and all related matters. The aim of this white paper is to provide a survey of definitions of immersion and presence which leads to a definition of immersive media experience (IMEx). The Quality of Experience (QoE) for immersive media is described by establishing a relationship between the concepts of QoE and IMEx followed by application areas of immersive media experience. Influencing factors on immersive media experience are elaborated as well as the assessment of immersive media experience. Finally, standardization activities related to IMEx are highlighted and the white paper is concluded with an outlook related to future developments.

QUALINET 沉浸式媒体体验定义白皮书 (IMEx)

随着虚拟/增强现实和交互式媒体时代的到来，从计算机图形到文学作品的不同领域出现了许多沉浸式定义、框架和模型。沉浸通常与存在互换使用，因为这两个概念密切相关。然而，在定义、范围和组成部分方面存在明显的跨学科差异，需要解决这些差异，以便对概念有一致的理解。这种共识对于为沉浸式媒体体验 (IMEx) 和所有相关事项的未来方向铺平道路至关重要。本白皮书的目的是对沉浸式和临场感的定义进行调查，从而得出沉浸式媒体体验 (IMEx) 的定义。沉浸式媒体的体验质量 (QoE) 通过在 QoE 和 IMEx 的概念之间建立关系来描述，然后是沉浸式媒体体验的应用领域。阐述了影响沉浸式媒体体验的因素以及沉浸式媒体体验的评估。最后，重点介绍了与 IMEx 相关的标准化活动，并以与未来发展相关的展望结束了白皮书。
