摘要 |
When eye movement of a subject is detected by an eye movement detecting portion (2) and head movement of the subject is detected by a head movement detecting portion (3), a line-of-sight calculating portion (1) calculates the line-of-sight according to the detected outputs therefrom. A portion (6) for generating an image to be presented generates an image as a task and presents the image to a task presenting portion (9). When a fixation point of the line-of-sight of the subject is determined by a fixation point determining portion (4), a mask image generated by a masking image generating portion (7) is inserted to the task image by an image synthesizing portion (5), and it is presented at the task presenting portion (9). A portion (11) for determining degree of advance of dementia determines degree of advance and possibility of Alzheimer's disease based on the particular movement of the line-of-sight of the subject at that time and on the percentage of correct answer to a prescribed task. <IMAGE> |
