[DEMO] Displaying free-viewpoint video with user controlable head mounted display DEMO

In this paper, we propose a method to experience a free-viewpoint video and image with a head mounted display (HMD) and a game controller that enable to operate it intuitively. The free-viewpoint video is generated by multiple 4K resolution cameras in sport games such as soccer and american football. This method can provide us a player´s perspective. We adopt a billboard method to make a free-viewpoint video which is consisted of multiple textures accoding to user specified viewpoint. For implementing the program and displaying images effectively we used a game development system, a HMD and a game controller that user can operate their own views in the high degree of freedom. Experiment results show that the proposed method can obviously achive effective view.
