Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram illustrating a cursor position control method according to an embodiment of the present invention. In the figure,
The panoramic camera 1 is a camera that is fixed above the human head so as to face the front of the human and captures the entire visual field of the human. The line-of-sight detector 2 is a device that detects the line of sight from the movement of the human eyeball. The viewpoint calculator 3 is a device that calculates, based on the output of the line-of-sight detector 2, where in the image captured by the panoramic camera 1 a human is looking. The cursor position control device 4 is a device that controls the position of the cursor 7 displayed on the display device 5. The reference marker 6 is a mark for clearly indicating the coordinates on the surface of the display device 5, and the x, y coordinates on the surface of the display device 5 are (x,
y) = (0,0), (1,0), and (0,1).

Next, the operation of this embodiment will be described. The line-of-sight detector 2 observes the movement of the human eyeball and determines the angle α between the line of sight and the optical axis of the panoramic camera 1, the angle β with the direction directly above the human, and the angle γ with the direction right just above the human. Output. From these three angles, the viewpoint calculator 3 determines where the human viewpoint is on the coordinates on the image plane of the panoramic camera 1 by the following formula. x = Kcosαcosγ y = Kcosαcosβ where (x, y) are coordinates on the image plane of the human viewpoint, and K is a constant determined by the optical system of the panoramic camera 1, which is 1 m ahead of the panoramic camera 1. This is equivalent to the length of a 1 m long bar placed horizontally on the image plane of the bar.
