Augmented Reality Game Interface Using Effective Face Detection Algorithm

Viola and Jones Algorithmand Viola and Jones, the conventional face-detecting methods, have the advantages in that they could help fast and clear face recognition. But they also have their own drawbacks. With Viola and Jones, detection of slanted face is hard, and Viola and Jonescannot provide the precise recognition of faces since the detected area in faces is rather wide depending on the environment. To come with some kinds of solutions to these limitations, this paper propose the algorithm, which considers the position and size of the circle(the range of face recognition), detection intervals, and etc. The algorithm has been proven to be effective through a series of experiments. 3D AR game has been produced to utilize the algorithm as game interface in AR environment. Experiments in various game situations proved its effectiveness. Compared with the conventional methods, the algorithm was better in getting the desired information through face recognition, thus realizing interesting game interface. The algorithm could be used as the basis for making natural interaction with virtual object in augmented reality and also for developing interface in the smart environment.
