Abstract

본 발명은 가상 현실을 이용하여 구성된 3차원 가상 공간의 네비게이션을 좀더 효율적으로 하기 위한 3차원 가상 공간 탐색 시스템 및 방법에 관한 것이다.The present invention relates to a three-dimensional virtual space search system and method for more efficient navigation of a three-dimensional virtual space constructed using virtual reality.

기존의 3차원 가상 공간 네비게이션은 2차원 입력 장치를 이용하여 3차원 가상 공간을 네비게이션 하는 방법이 대부분이었고, 3차원 입력 장치를 이용하는 경우에도 3차원 입력 장치가 네비게이션에는 적합하지 않았다. 본 발명은 3차원 가상 공간 네비게이션을 효율적으로 하기 위한 하드웨어와 소프트웨어를 개발하여 3차원 가상 공간에서의 정보 이용을 높일 수 있다.Conventional 3D virtual space navigation has been mostly a method of navigating a 3D virtual space using a 2D input device, and even when using a 3D input device, the 3D input device is not suitable for navigation. The present invention can improve the use of information in the three-dimensional virtual space by developing hardware and software for efficient three-dimensional virtual space navigation.
