The report will identify the role of existing standards relevant to augmented reality and document any interoperability gaps. This activity will analyse the standardization work done around augmented reality in various standards setting organizations.
The present document provides a study on the QoE metrics relevant to VR service. The study focuses on:1. Defining a device reference model for VR QoE measurement points.2. Studying key performance indicators that may impact the experience of VR service.3. Identifying the existing QoE parameters and metrics defined in SA4 standards such as TS 26.247, TS 26.114 which are relevant to Virtual Reality user experience;4. Identifying and defining new QoE parameters and metrics relevant to Virtual Reality user experience, taking into consideration the use cases listed in TR 26.918, and any sources that show the relevance of new metrics, e.g. scientific literature, specifications/solutions from other standard organizations.5. Analysing potential improvements to the existing QoE reporting so as to better accommodate VR services.6. Providing recommendations to future standards work in SA4 on the QoE parameters and metrics and, as necessary, coordinate with other 3GPP groups and external SDOs, e.g. MPEG, ITU-T.
The scope of the present document is to investigate the relevance of Virtual Reality in the context of 3GPP. Virtual Reality is the ability to be virtually present in a non-physical world created by the rendering of natural and/or synthetic image and sound correlated by the movements of the immersed user allowing to interact with that world. With recent progress made in rendering devices, such as Head mounted displays (HMD), a significant quality of experience can be offered. By collecting comprehensive information on VR use cases, existing technologies and subjective quality, the report attempts to identify potential gaps and relevant interoperability points that may require further work and potential standardization in 3GPP in order to support VR use cases and experiences in 3GPP user services. The report primarily focuses on 360 degrees video and associated audio, which support three degrees of freedom (3DOF).
The present document defines the supported media formats, codecs, processing functions and guaranteed minimum performances per AR device category. The present document addresses the interoperability gaps identified in the conclusions of TS 26.998.
The present document defines interoperable formats for Virtual Reality for streaming services. Specifically, the present document defines operation points, media profiles and presentation profiles for Virtual Reality. The present document builds on the findings and conclusions in TR 26.918.
The present document provides reference test material and test results for improved usability of technologies in TS 26.118: Virtual Reality (VR) profiles for streaming applications.The specification TS 26.118 includes several VR media profiles for video and a single media profile for audio with different configuration options. The specification focuses primarily on interoperability requirements for VR360 applications, but does not address performance characterization of the solutions. In order for content providers and the rest of the ecosystem to be able to select and configure the technologies defined in TS 26.118 and to generate content for streaming applications, collecting such information would be most valuable.

This document specifies syntax and semantics of the data formats for interaction devices by providing a standardized format for interfacing actuators and sensors by defining XML schema-based language named Interaction Information Description Language (IIDL). IIDL provides a basic structure with common information for communication with various actuators and sensors in consistency. Device Command Vocabulary (DCV) is defined to provide a standardized format for commanding individual actuator, and Sensed Information Vocabulary (SIV) is defined to provide a standardized format for holding information from individual sensors either to get environmental information from real world or to influence virtual world objects using the acquired information on the basis of IIDL.
Technical framework, application processes and technical requirements for carbon trading applications based on blockchain, including functions, access, interface, security, and carbon consumption voucher coding are described in this standard.
