The Milky Way is visible from every city, town, and village in Tottori Prefecture, and even during meteor showers, it is easy to see shooting stars. Unfortunately, however, the starry sky cannot be seen if the weather is unfavorable.
　Therefore, in 2019, Tottori Prefecture held a public call for VR experience contents of the starry sky using VR, and our proposal was adopted.

IN 2019, OUR CONTRACTED PROJECTS INCLUDED FILMING AND CONTENT PRODUCTION OF 360 VIDEOS AND PROMOTIONAL FLAT VIDEOS OF THE STARRY SKY VR, AND DEVELOPMENT OF VIEWING APPS FOR SIMULTANEOUS VR PLAYBACK OF CONTENT AND IMPLEMENTATION OF STARRY SKY QUIZZES. WE ALSO DEVELOPED A VIEWING APPLICATION FOR THE COLLABORATION PROJECT BETWEEN JR WEST'S SIGHTSEEING TRAIN "WEST EXPRESS GINGA" AND TOTTORI PREFECTURE, WHICH STARTED SERVICE ON SEPTEMBER 11, 2020, WHICH ALLOWS PASSENGERS TO VIEW STARRY SKY VR VIDEOS OF TOTTORI PREFECTURE INSIDE THE TRAIN.

FOR THE STARRY SKY VR AND PROMOTIONAL VIDEOS, TIME-LAPSE PHOTOGRAPHY WAS CONDUCTED USING 250-DEGREE FISHEYE AND WIDE-ANGLE LENSES AND SLR CAMERAS. THE VIDEOS WERE SHOT AT TOTTORI SAND DUNES, SAJI ASTRO PARK, MT. DAISEN, AND HASHIDZU BEACH, WHICH ARE STARRY SKY SPOTS IN THE PREFECTURE. WE ARE PRODUCING CONTENTS.

For the configuration of the video viewing application, OculusGo, which is inexpensive and easy to use, was adopted as the hardware (HMD), and software was developed for Android terminals for monocular viewing for children. Since the application was designed not only to operate as a stand-alone application, but also to be viewed by multiple people simultaneously, we developed an application that can control multiple HMDs/Android terminals from a PC via a network to realize content selection and simultaneous playback/stopping.
　In addition, we developed an application for the "starry sky quiz" function by enabling questions to be submitted from the PC as described above, so that users can enjoy the quiz even when they cannot see the starry sky.

Currently, the "Hoshitori Prefecture" content we produced and the hardware set we delivered are being rented out through the Tottori Prefectural Tourism Exchange Bureau to travel agencies and other organizations in the prefecture for use at various events.
