In this paper, we propose a new method for virtual three dimensional (3D) user interface system via motion estimation of moving object in image sequences from single camera. Log-polar transform in the spatial domain and phase correlation method are used to estimate rotation and scale between a template object and the object in the next frames of video sequences. Kalman filtering is utilized to smooth the high frequency variation of the rotation and scale motions. Translation of object motion can be estimated through template matching by dynamically updating template for each frame. Based on the estimated motions, we demonstrated a human interface system, which allows a user to control a computer mouse such as mouse clicks and horizontal and vertical movement of mouse cursor, and then estimated object space coordinates of two dimensional (2D) position of the mouse cursor. The object space coordinates and estimated motion parameters of the rotation and scale are used as 3D input for 3D model drawing and controlling. These procedures are implemented in very simple real-time 3D application systems.
