発明の名称 (英語) Autism diagnosis support apparatus コモンズ
発明の概要(英語) An autism diagnosis support apparatus 1 according to the present invention is an autism diagnosis support apparatus that detects a symptom of autism based on a state of a subject looking at a target, including: an eye-gaze point detection unit 2 that detects a line-of-sight direction of the subject looking at the target; a color camera 3 that takes an image of the target; a pupil position detection unit 4 that measures a pupil coordinate of the target; and a data analysis unit 7 that calculates a relationship between the line-of-sight direction of the subject and a pupil position of the target using the line-of-sight direction and the pupil coordinate and outputs the relationship along with the image of the target.
従来技術、競合技術の概要(英語) BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an autism diagnosis support apparatus using a diagnostic of autism.
2. Related Background Art
Autism is a developmental disorder occurring in infants aged up to three, and one in 50 to 60 people develops autism and related disorders.
Typical symptoms of autism include impaired communication due to inability to make eye contact, lack of emotional interaction due to an inability to imagine the feelings of others, and display of limited interests and behaviors.
Attempts have been made to improve social adjustment of autistic people by early autism diagnosis for early start of remedial education.
For example, pediatricians and child psychiatrists have diagnosed autism by observing behaviors of infants and making an evaluation based on their behaviors.
However, the shortage of specialists in such diagnosis approach makes early diagnosis practically difficult.
Other approaches to autism diagnosis under consideration include biological evaluation such as a specific serum molecular method.
This diagnosis approach involves analyzing a patient's serum to identify the patient as healthy or autistic.

特許請求の範囲(英語) [claim1]
1. An autism diagnosis support apparatus that detects a symptom of autism based on a state of a subject looking at a target, comprising: a line-of-sight detection unit that detects a line-of-sight direction of the subject looking at the target;
a camera that takes an image of the target;
a pupil position detection unit that measures a pupil coordinate of the target; and
a data analysis unit that calculates a relationship between the line-of-sight direction of the subject and a pupil position of the target using the line-of-sight direction and the pupil coordinate and outputs the relationship along with the image of the target.
[claim2]
2. The autism diagnosis support apparatus according to claim 1, further comprising an eye-gaze point detection unit that calculates an eye-gaze point coordinate from a predetermined plane on which the target is seen and the line-of-sight direction, wherein the data analysis unit calculates a relationship between an eye-gaze point of the subject and the pupil position of the target using the eye-gaze point coordinate and the pupil coordinate and outputs the relationship along with the image of the target.
[claim3]
3. The autism diagnosis support apparatus according to claim 2, wherein the eye-gaze point detection unit comprises: a camera that takes an image of the subject;
the line-of-sight detection unit that detects the line-of-sight direction of the subject based on the image; and
an eye-gaze point calculation unit that calculates the eye-gaze point coordinate of the subject on the predetermined plane based on the line-of-sight direction, wherein
the pupil position detection unit further detects a line-of-sight direction of the target based on the pupil position of the target.
[claim4]
4. The autism diagnosis support apparatus according to claim 3, wherein the data analysis unit further calculates a relationship between the line-of-sight direction of the subject and the line-of-sight direction of the target.
[claim5]
5. The autism diagnosis support apparatus according to claim 3, wherein the pupil position detection unit calculates the pupil coordinate of the target based on a bright pupil image and a dark pupil image of the target and detects the line-of-sight direction of the target using the pupil coordinate and a corneal reflection position of the target.
