PROBLEM TO BE SOLVED: To provide an objective index of a user's meditation state using proper parameters and criteria.SOLUTION: The information processing method causes a control unit to: acquire strength data representing eyeblink strength measured on the basis of an eye potential of an object person's eye and presence/absence data representing presence/absence of the eyeblink； acquire posture data representing at least one of data representing back/forth movement based on respective sensor signals from an acceleration sensor and an angular sensor, second data representing left/right movement, and data representing direction and dimension of inclination of a body axis； calculate stability data representing stability of a posture of the object person on the basis of the posture data, first average data representing an average value of the eyeblink strength on the basis of the strength data, and second average data representing an average value of eyeblink intervals on the basis of the presence/absence data； and calculate a posture control evaluation value related to the posture control on the basis of the stability data, a breathing control evaluation value related to the breathing control on the basis of the first average value, and a mind control evaluation value related to mind control on the basis of the second average data.SELECTED DRAWING: Figure 4【課題】ユーザの瞑想状態について、妥当なパラメータ及び基準を用いて客観的な指標を提供する。【解決手段】情報処理方法であって、制御部は、対象者の眼の眼電位に基づき計測された瞬目強度を示す強度データ、及び瞬目の有無を示す有無データを取得し、加速度センサ及び角速度センサからの各センサ信号に基づく前後のブレを示すデータ、左右のブレを第２データ、及び体軸の傾きの方向と大きさを示すデータのうち少なくとも１つを表す姿勢データを取得し、姿勢データに基づいて対象者の姿勢の安定性を示す安定性データと、強度データに基づいて瞬目強度の平均値を示す第１平均データと、有無データに基づいて瞬目間隔の平均値を示す第２平均データとを算出し、安定性データに基づいて調身に関する調身評価値と、第１平均データに基づいて調息に関する調息評価値と、及び第２平均データに基づいて調心に関する調心評価値を算出する。【選択図】図４
