초록

(Background and Purpose)There has been a soaring demand in the market for VR content area in 2016, the starting year of growth in VR(Virtual Reality) ecosystem. However, there is a lack of contents in terms of both quantity and quality as VR content development in Korea has been led primarily by small and medium-sized enterprises. Under those circumstances, the purpose of this study was to present production and detailed workflow systematically in connection with development of Namseoul University campus VR contents targeting freshmen for the purpose of VR commercialization. (Method)1) Types of HMD and VR environment configuration conditions were presented on the basis of virtual reality(VR) theory. 2) The researcher analyzed subjects of each content, producers, content production techniques and characteristics in order to derive production techniques and scenario applicable to contents of VR common platform. 3) The production and detailed workflow were presented systematically based on case analysis in relation to development of interactive VR contents for campus of N University. (Results)The system and systematic stages for production of N University campus VR contents were as follows: 1) The intention of VR content development was to allow freshmen of N University to gain proactive experience with virtual campus tour. For that, a lot of experience-related information was provided regarding the location, names, purposes, etc., of buildings. 2) For shooting equipments, the researcher prepared 7 units of GoPro with an output of up to 4K, holders, remote controllers, battery chargers, SD cards, tripods, etc. Edition in latter part of process can be facilitated when subjects are at least 2m apart from each other in the case of 360° VR shooting. It is important to ensure that staffs are hidden so as to prevent them from being captured by camera. 3) 360° stitching and special effect(VFX) is a process to convert 7 images into single 360° image through stitching procedure. It requires special technique involving the use of 4 programs and therefore constant research is needed. 4) The latter part of process enabling the experience of 360° VR image through HMD was designed with engines such as unity or unreal, etc. (Conclusions) Based on the results of this study, the course of VR content development can be presented as below: 1) Interactive space design which combines virtual contents and real space can be created by using LBS(Location Based Service) and motion recognition technology(Kinect), etc. 2) 360° image has been evolving into 360° real-life shooting, 360° selective and 360° mobile contents, and also developing into converged contents such as 360° image + 3D modeling, 360° image + interaction, etc. 3) Images shoot at 360° can find various applications such as many different VR devices, 360° web, etc. Based on overall consideration of aforesaid results, HMD-based VR interactive contents are evolving into interactive information space combined with real space through development of image shooting technology, VR technology, and devices. Thus, HMD-based VR interactive contents are expected to develop into virtual training spatial design, virtual entertainment spatial design, virtual interactive entertainment spatial design, virtual interactive education spatial design, etc., and researches need to be carried out on those spatial designs.
