To presume a one-side abnormal state in which a subject feels it inconvenient on either of right and left sides of his or her body.SOLUTION: A saccade detection unit (301) detects a saccade of a subject. A presumption unit (302) presumes that the subject is in a one-side abnormal state in which either of right and left sides of a body is abnormal when an amplitude (ds) of the saccade in a presumption period (P1) is equal to or less than a small amplitude threshold value (dthL), and a frequency (fs) of the saccade in the presumption period (P1) is equal to or greater than a frequency threshold value (fthH).SELECTED DRAWING: Figure 13
【課題】身体の左右の片側に不自由さを感じる片側異常状態を推定する。【解決手段】サッケード検出部(301)は、対象者のサッケードを検出する。推定部(302)は、推定期間(P1)内におけるサッケードの振幅(ds)が小振幅閾値(dthL)以下であり、且つ、推定期間(P1)内におけるサッケードの頻度(fs)が高頻度閾値(fthH)以上である場合に、対象者の状態が身体の左右の片側に不自由さを感じる片側異常であると推定する。【選択図】図13
