다차원 정보 탐색을 위한 큐브 기반 복합 인터페이스 디자인

This study began by judging the characteristics of the 3D interface as the multifacetedness of information and the autonomy of manipulation, and searching for multidimensional information in VR, a 3D medium. The purpose of this study is to propose a 3D interface in VR that extends the Space-Time Cube to search for place information, which is multidimensional information. Therefore, in this paper, a design choice was made to reduce the cognitive load of users in the process of acquiring complex information by simultaneously providing 2D and 3D spaces through each side of the cube. Also, through a comparative experiment between the two-dimensional interface 'window type' and the three-dimensional interface 'cube type', the hypothesis about usability and cognitive load according to the shape of the interface was verified. The research of this study are as follows. First, the three-dimensional cube type interface is efficient for searching multidimensional information. This is because the cube type provides two-dimensional information through the side of the cube and at the same time provides the three-dimensional information in the cube in semi-transparent manner, so it is possible to easily grasp the multidimensional information at once. Second, in order to improve the accuracy of the 3D interface, it is important to provide 2D interface together and to solve the problem related to visual congestion. Therefore, it can be seen that it is necessary to provide appropriate information exposure, a clear hierarchy between information, and options to control this. Third, the difficulty of 3D manipulation can be improved with auxiliary interface design. In this study, the operability of the cube type was improved by adding an auxiliary element that can easily rotate the cube. Based on these research results, it is expected that the cube model can be used in various ways for multidimensional search as a form of 3D interface.
