Unity3D-based app for 360VR subjective quality assessment with customizable questionnaires

This document describes an interactive virtual reality tool for subjective assessment designed under the scope of ITU-T Study Group 12 and the Video Quality Experts Group in the development of the future ITU-T Recommendation P.360-VR for the subjective assessment of 360 videos using Head-Mounted Displays (HMDs). The tool has been designed under the Unity3D engine to be used on multiple HMDs. Furthermore, it can be configured for a variety of custom or predefined questions while the video sequence is played and/or after its ending. The head tracking is also registered in degrees. The voting method is gaze-based using joysticks keys for confirmation.
