KT Corporation
Providing virtual reality experience service

Abstract:

A user device and a server provide a VR experience service to a user without significant interruption in response to a user's movement. In particular, the server may create a stitched image of a 360-degree video of a predetermined virtual environment according to a user movement state and transmit the stitched image to a user device. The user device may i) receive, from a server through a wireless link, a stitched image of a 360-degree video of a predetermined virtual environment which is dynamically changed according to a user movement state and ii) render a stereoscopic image at a user's view-point which is dynamically changed according to a user's head movement, using the received stitched image of the 360-degree view of the predetermined virtual environment.
