Cloud VR Presence Index (VR PI) White Paper


This white paper describes cloud virtual reality (VR) service experience evaluation, including the requirement background, evaluation model framework, subjective experiment and analysis method, model formula structure, typical model values, and model application scenarios. The industry's first VR device high-pixel per degree (PPD) equivalent test and multi-degree of freedom (DOF) interactive test allow the VR service experience evaluation model not only to be applicable to status evaluation, but also to provide forward-looking guidance for VR service future development.
