This Recommendation focuses on aspects of importance for the assessment of quality of experience (QoE) of different types of extended reality (XR) telemeetings, which may be a combination of telemeetings taking place in virtual reality (VR), augmented reality or mixed reality environments. It targets XR services aiming to immerse the user and augment the exchange of information by delivering interactive real-time uni- or multimodal sensory information for two-party and multiparty communication. The services include telemeetings taking place in a virtual location or a combination of virtual and real locations; telemeetings with mixtures of real and virtual participants; telemeetings with augmented elements for collaboration; virtual conferences; and joint teleoperation of equipment.

While multiple QoE evaluation methodologies for telemeetings have been developed, novel XR telemeeting services may result in cognitive effects that are not covered by the existing Recommendations. These effects may include simulator sickness, fatigue, immersion or presence, for example. This Recommendation advises on the key QoE factors affecting user experience of an XR telemeeting service.

The purpose of this Recommendation is to find existing standardized methods that can be applied for assessing the QoE constituents of XR telemeetings, and direct the reader to the appropriate source. When a suitable standardized method is not available, this Recommendation will list the QoE influencing factors related to the QoE constituent in question and guide the reader to relevant scientific literature. Ultimately, this Recommendation specifies the categorization of system, human and context factors influencing XR telemeeting QoE.
