실감 콘텐츠의 체험적 특성 요소에 관한 연구 - HMD와 3면 Virtual Reality Surround-Screen Projection System을 중심으로 - = A study on Experiential Characteristics of Immersive Content - Focusing on HMD and Virtual Reality Surround-Screen Projection System

다국어 초록 (Multilingual Abstract)

(Background and Purpose) The offline experience of virtual reality's immersive content is being organized in exhibition halls or multi-use facilities frequented by many users. In order to build a realistic content experience environment, it is necessary to select an appropriate medium according to the experiential characteristics of the content and the installation environment. A 3-sided Virtual Reality Surround-Screen Projection System in the form of a CAVE (Cave Automatic Virtual Environment) is a medium that can be used by multiple users simultaneously. It is a structure in which the user enters the room surrounded by the screen and immerses the whole body (Full Body Immersion), and does not wear a separate device. The HMD (Head Mounted Display) type is a medium in which the user wears it on the head. This study aims to present experiential characteristics for evaluating HMD, a medium for experiencing immersive content, and a Virtual Reality Surround-Screen Projection System. Therefore, in this study, items to evaluate the media were presented by deriving experiential characteristic elements with high correlation between the two media. (Method) The analysis model examined and classified the experiential characteristic elements according to the device characteristics of the two media. Prior studies of overseas and domestic cases of virtual reality user experience were investigated, and elements of evaluation items were derived and organized. In this study, the experiential characteristics of the elements were derived by classifying the items to be evaluated in each of the two media by analyzing previous studies on the experiential characteristics of virtual reality, focusing on the device characteristics of a HMD and Virtual Reality Surround-Screen Projection System. (Results) Accordingly, in this study, experiential characteristic elements of HMD and Virtual Reality Surround-Screen Projection System are presented to evaluate media suitable for immersive content, so that it is possible to evaluate the experiential medium according to the contents. With the expansion of virtual reality immersive content and the popularization of virtual reality experiences, the expansion of real-world experience spaces, including multi-use facilities, can be expected. Provides analysis elements of experiential characteristics for comparison of two media. (Conclusion) The expansion of the virtual reality market is expected to require evaluation by researchers and field experts on various experience media. In this study, in the virtual reality experience, it is possible to evaluate experiential characteristics by presenting the experiential feature elements of the Virtual Reality Surround-Screen Projection System that multiple users experience simultaneously without wearing the HMD and device worn by the user.
