손동작을 이용한 인간친화형 증강현실 인터페이스

초록

A number of augmented reality interfaces have been developed for past decades, which used to have environmental or ergonomic limitation by requiring 3-D hand model or tracking hardware such as data glove. For example, even though marker-based interfaces guarantee accuracy and convenience in implementation, the marker may be visually intrusive to user, because a marker has distinct of shape and color from the scene. Moreover, it is difficult to provide natural (usually complicated) user interactions using markers. On the other hand, interface based on gesture recognition can provide natural user interactions, but the recognition rate is usually low. This paper proposes an efficient hand gesture recognition method and a natural AR interface using the method. The proposed method can provide natural interaction to users with less computational cost. It also achieves a greatly enhanced recognition rate of hand gestures by using a color band. The color information of the color band put on user's wrist extracts the hand-region in a fast and accurate manner. User can freely control virtual object using the proposed interface. For example, virtual objects can be shown up in the area where the user is pointing, can be handled and disappeared as the user controls. We verify the effectiveness of our interface by comparing with a marker-based AR interface through user evaluation.
