Abstract
With the improvement of virtual reality (VR) technology and the spread of VR equipment, attention to VR services has increased, and a variety of new VR services have appeared. Among them VR services with interaction require real time synchronization of the user’s position in the space, actions taken, and other information, so it is important to increase the speed of communication to maintain the quality of the user experience. However, when synchronizing information between users using a cellular network, it is difficult to speed up communication for all terminals because multiple terminals share the same network and the cellular resources allocated to each terminal are limited. Therefore, it is necessary to clarify the characteristics of applications that should be prioritized for communication among VR applications that involve interaction and the extent to which communication delay affects the quality of user experience in order to do appropriate cellular resources allocation that do not impair the quality of user experience. In this study, VR services that involve information processing of user interaction are implemented on actual devices, and the user experience quality is measured in an environment with multiple different communication delays. The results provide data on the characteristics of VR applications with interaction that should reduce the amount of delay, as well as data related to the quality of the experience when running in own 5G environment.
