초록

본 논문에서는 사용자들이 손쉽게 마커기반과 제스처 상호작용 방법들을 적용한 증강현실 콘텐츠를 제작할 수 있는 증강현실 저작도구 시스템을 제안한다. 기존의 증강현실 저작도구들은 가상의 객체를 증강하는데 초점이 맞춰져 있었고, 이러한 증강현실 콘텐츠와 상호작용을 하기 위해서는 사용자가 마커나 센서를 이용하는 방법을 사용하였다. 우리는 이러한 제한적인 상호작용 방법의 문제점을 마커기반 상호작용 방법과 깊이 인식 카메라인 Kinect를 사용한 제스처 상호작용 방법을 적용시킴으로써 해결하고자 한다. 제안하는 시스템에서는 사용자가 인터페이스를 통하여 간단한 형태의 마커기반 증강현실 콘텐츠를 쉽게 제작할 수 있다. 또한, 능동적으로 사용자가 증강현실 콘텐츠와 상호작용할 수 있는 방법들을 제공하고 있다. 본 연구에서 제공하는 상호작용 방법으로는 마커기반의 상호작용 방법으로 2개의 마커를 이용한 방법과 마커의 가림현상(Occlusion)을 이용한 방법이 있다. 그리고 사용자의 맨손을 인식, 추적하여 객체의 확대 축소, 이동, 회전이 가능한 제스처 상호작용 방법을 제공한다. 저작도구 시스템에 대한 사용성 평가와 마커 및 제스처 상호작용에 대한 사용성을 비교평가하여, 본 연구의 긍정적 결과를 확인하였다.

In this paper, we suggest an augmented reality authoring tool system that users can easily make augmented reality contents using hand gesture and marker-based interaction methods. The previous augmented reality authoring tools are focused on augmenting a virtual object and to interact with this kind of augmented reality contents, user used the method utilizing marker or sensor. We want to solve this limited interaction method problem by applying marker based interaction method and gesture interaction method using depth sensing camera, Kinect. In this suggested system, user can easily develop simple form of marker based augmented reality contents through interface. Also, not just providing fragmentary contents, this system provides methods that user can actively interact with augmented reality contents. This research provides two interaction methods, one is marker based method using two markers and the other is utilizing marker occlusion. In addition, by recognizing and tracking user's bare hand, this system provides gesture interaction method which can zoom-in, zoom-out, move and rotate object. From heuristic evaluation about authoring tool and compared usability about marker and gesture interaction, this study confirmed a positive result.
