<p><P>PROBLEM TO BE SOLVED: To provide a gesture interface system using a featured wand for camera calibration and a gesture based 3D interface device, a wand for gesture input, an application control method, a camera calibration method, and a control program. <P>SOLUTION: Passive wands, tracked by one or more cameras, are used as user interface devices. The wands are inexpensive, and are a natural way for users to interact with devices such as large displays. Each wand may be used to specify a full 6 degrees of freedom, which can be helpful for manipulation of 3D applications. The wands may also be used to identify 3D world points, which is useful for multi-camera calibration, and for building 3D models of physical spaces. The described methods provide a more precise estimation of wand pose, and can be implemented with a single camera. Also described is a method for estimating wand pose using information available along a one dimensional 'line scan' within the image, which simplifies processing. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
