PROBLEM TO BE SOLVED: To suppress an erroneous determination as if there were sleep time during an activity time zone of a person to be observed.SOLUTION: A sleep state determination system 10 may include an activity meter 2 for measuring an amount of activity of a person to be observed, and an information processing device 1. The information processing device 1 may include a storage part 13 and a processing part 11. The storage part 13 may store schedule information on the person to be observed. The processing part 11 may acquire data of the amount of activity measured by the activity meter 2, and determine a state on the sleep of the person to be observed based on the acquired data of the amount of activity and the schedule information stored in the storage part 13.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】被観測者の活動時間帯に睡眠時間が存在するかのような誤判定を抑制する。【解決手段】睡眠状態判定システム10は、被観測者の活動量を測定する活動量計2と、情報処理装置1と、を備えてよい。情報処理装置1は、記憶部13と、処理部11と、を備えてよい。記憶部13は、被観測者のスケジュール情報を記憶してよい。処理部11は、活動量計2によって測定された活動量データを取得し、取得した活動量データと、記憶部13に記憶されたスケジュール情報と、に基づいて、被観測者の睡眠に関する状態を判定してよい。【選択図】図1
