<P>PROBLEM TO BE SOLVED: To easily measure a visual field range at any time even by one person by providing a function near an actual apparatus and a functionality of a computer. <P>SOLUTION: A stereoscopic video display device alternately displays an image for a left eye and an image for a right eye on either side corresponding to left and right eyes on a display screen, and an observer uses a three dimensional image displaying device recognizing stereoscopic images consisting of a long distance depth image and this side image near jumping out of a screen with the screen as a reference by observing these images through spectacles. While a sphere like a small point circulates right and left from back long distance of the screen, the sphere approaches to this side, becomes gradually large, finally jumps out from the screen and displays so that the images may press even in the face of a subject while circulating. Thereafter, the sphere is moved to the central part of the screen stood to be displayed in a still state, and eyeballs are maintained on a screen frontal. A bright point image is separately displayed on arbitrary coordinate values of the screen, a subject replies this bright point image after visual recognition, and records the replied bright point image coordinate values. The recorded plurality of the coordinate values are displayed at positions on the screen. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
