공간인지 능력이 있는 증강현실 전시 콘텐츠 설계 및 구현

Abstract

Augmented reality (AR) exhibit contents came to represent a large part of the exhibition media with the public interest and the popularization of hardware. The AR technology can use the various senses of users, combined with the role of providing information about exhibits, with the method of augmenting virtual objects in the real world seamlessly, which provides high immersion and a sense of reality. The existing AR exhibit contents mostly augment exhibits or deliver information through texts and images. However, the location-based AR causes a phenomenon in which virtual objects are incorrectly matched with the real world due to the error of GPS information, which decreases realism. Vision-based AR for more accurate matching can be augmented in the position where a marker is placed, but since a geometric pattern reduces the concentration of the user's experience, and it can only be augmented when the marker is perceived, immersion becomes lower, so there is a limitation in providing contents. Project Tango developed to resolve this problem can perceive the distance of things that exist in the real world with the motion tracking method through a fish eye camera and an infrared camera, and learn spaces, so it is an AR technology that can create and share virtual spaces. This study designed and implemented exhibit contents that interact with the real world, utilizing Project Tango, an AR technology that can make spatial perception. Dividing the screen for the administrator and user, the proposed contents arrange the virtual objects of exhibits in the real space and provide information with various methods, such as text, audio, image and video for the administrator. The contents were designed so that the virtual objects on a real object are augmented when the user arrives near the position that the administrator has registered in advance, and the user can design information about exhibits, touching the relevant virtual objects. The proposed exhibit contents implemented AR using Project Tango SDK in Unity 3D based on Lenovo Phab 2 Pro and implemented virtual objects for the exhibit contents in museums, utilizing C#. Exhibit contents implemented in this study could enhance immersion and sense of reality, which would be combined with various exhibition areas like shopping malls as well as museums.
