In this paper, the authors propose a 3D coordinate estimation for 3D space using a mono camera in mobile devices. Generally, a marker is used for the detection of 3D movement in 2D images. However, this marker-based system has obvious defects since markers always need to be included in the image. To overcome this problem, they replaced the markers with a planar face by estimating the face detection. The experimental result indicates the feasibility of the proposed algorithm for face movement-based mobile user interfaces.
