Effective Interface Design Using Face Detection for Augmented Reality Interaction of Smart Phone

This study proposes effective interface by using face-detection information, which comes from input image of the camera installed on a smart phone, and also by using movement information from reliable characteristics of the object. To do this, augmented reality interface has been constructed by putting the virtual object onto the camera image of the real space. The gamer and the virtual object, which are put in two separate spaces, engage in various real-time interactions such as attack, defense and alert. Difference image per frame of the tracked object information was employed to check if the hand has touched the interested area. Its effectiveness has been proven through experiment. Infusion technology, which combines TTS (text to speech) and vibrating sensor installed on a smart phone, was applied to provide emotional information to help the game participant to get immersed in the game. The proposed method could be applied as the basic material for AR interface.
