Abstract
In this paper, we proposed a technique in which subtitles are followed according to changes in the user's viewpoint in 360 VR. Create a Sphere object in Unity's Scene and insert a 360-degree image on the surface of the Sphere object. At this time, the ReverseNormals script is used to convert the viewpoint to the inside. The SightOrbitproved script is used to modify the camera view. Use this script to set the environment in which subtitles can move depending on the viewpoint. Next, add the 3D text (subtitle) that the user wants to the lower layer of the main camera and build a 360 VR object. The 3D text subtitles implemented through this study were compared according to the change of the user's viewpoint. As a result, as the viewpoint changes, normal subtitles flow out of line of sight according to the user's point of view, but 3D Text subtitles move according to the user's point of view, and it can be seen that the user can always view the subtitles.
