  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.
