Apparatus for medical diagnosis utilizing masking of fixation point
摘要
When eye movement of a subject is detected by an eye movement detecting portion and head movement of the subject is detected by a head movement detecting portion, a line-of-sight calculating portion calculates the line-of-sight according to the detected outputs therefrom. A portion for generating an image to be presented generates an image as a task and presents the image to a task presenting portion. When a fixation point of the line-of-sight of the subject is determined by a fixation point determining portion, a mask image generated by a masking image generating portion is inserted to the task image by an image synthesizing portion, and it is presented at the task presenting portion. A portion 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.
