Realization of Multi-User Tangible Non-Glasses Mixed Reality Space

Background/Objectives: Studies on convergent space, where multiple users can participate simultaneously, are lacking despite the spatial characteristic of mixed reality space where several people can coexist. Methods/Statistical Analysis: Based on the Unity3D engine, four-sided mapping was done using a multi camera in a CAVE type space. An autostereoscopic 3D image was provided by forming a parallax barrier using binocular disparity, and a space capable of multiple user participation was formed by implementing a multi-tracking system using Kinect. Findings: The development of technologies that allow autostereoscopic virtual reality and mixed reality experiences are currently underway, but a technology that can implement a mixed reality space for multiple users to experience virtual reality without special glasses in a real spatial environment is still in the development stage. The present study created an autostereoscopic 3D environment for resolving user discomfort, and implemented a multi-tracking system aimed at multiple user participation. As a result, the study was limited in that the definition of the screen differs depending on the light in accordance with the characteristics of beam projectors and that the restrictions to CAVE space only allows a restricted number of personnel to participate. Application/Improvements: Active research must be conducted on contents that are usable in mixed reality space implemented for vitalizing virtual reality space research.
