発明の名称 (英語) Autism diagnosis support apparatus コモンズ
発明の概要(英語) (US8371693)
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.
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.
