<p><P>PROBLEM TO BE SOLVED: To provide a user interface for specifying an object pointed by a user from an image of a camera worn on the head of the user. <P>SOLUTION: This user interface 10 comprises the camera 12 worn on the head of the user, a storage device 18, a 3D sensor for specifying the position and attitude of the camera, and an image processing apparatus 16. The storage device 18 stores an environmental model 22 obtained by modeling the 3-dimensional arrangement of surrounding objects, the vector V from the camera to the user's eyes, and the distance L between the camera and an index point predetermined on the user's hand. The image processing apparatus 16 executes index point calculation processing of calculating the position of the index point on the image, an indication vector calculation processing of calculating an indication vector extending from the user's eyes to the index point based on the calculated position, vector V, and distance L, and an object specifying processing of specifying the object positioned in the extending direction of the indication vector in virtual space by mapping the indication vector in the virtual space. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
