<p><P>PROBLEM TO BE SOLVED: To provide a technique facilitating acquisition of a motion of visual line of a person. <P>SOLUTION: In an irradiation control device 1, a light beam irradiation means 11 irradiates an eyeball E of the person with near infrared ray, an eyeball imaging means 12 takes an image of the eyeball E while irradiating the eyeball with near infrared ray, a visual line calculation means 13 measures a moving quantity of the eyeball E based on the taken image to detect a visual line direction. An irradiation device drive control means 21 changes the emitting direction of infrared ray by an infrared ray irradiation means 23 to the detected visual line direction. According to this, since infrared ray is emitted in the visual line direction of a subject (customer) wearing the irradiation control device 1 on the head, an analyzer (treatment person) can acquire the motion of visual line of each subject in real time by wearing a head mount display (HMD) 3 having infrared ray photographing function. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
