¿µ¹®³»¿ë¿ä¾à The standard describes quantitative video quality indicators, which is a key factor in determining the quality of experience of virtual reality service using a head mounted display. The virtual reality service quality can be defined as the level of the immersion of the user. The video has the greatest influence on immersion.
In order to naturally express the interactive video in head mounted display, both the hardware technology and the technology of shooting, producing and editing the virtual reality contents are important.
The screen quality such as detail, angle, and accuracy is composed of the resolution, pixels per inch, the field of view, and aberration. The naturalness of the video can be explained by the average frame rate and the frame rate uniformity. The response of the video according to the user's head motion can be expressed by the change recognition accuracy and the change delay time.
