To provide a seat capable of estimating a posture of a seated person in real time.SOLUTION: One embodiment of the present disclosure is a seat including: a seat body; at least one three-axis acceleration sensor arranged on the seat body; and an estimating device for estimating a posture of a seated person sitting on the seat body. The estimating device includes: a storage unit for storing a learning model constructed by machine learning by input data on the basis of the sensor output of at least one three-axis acceleration sensor and teacher data on the basis of information on a posture of the seated person or transition of the posture of the seated person; and an estimating unit for estimating the posture of the seated person or the transition of the posture of the seated person from the sensor output, using the learning model.SELECTED DRAWING: Figure 1

    【課題】着席者の姿勢をリアルタイムに推定できるシートを提供する。【解決手段】本開示の一態様は、シート本体と、シート本体に配置された少なくとも1つの3軸加速度センサと、シート本体に着座した着席者の姿勢を推定する推定装置と、を備えるシートである。推定装置は、少なくとも1つの3軸加速度センサのセンサ出力に基づく入力データと、着席者の姿勢又は着席者の姿勢遷移に係る情報に基づく教師データとによる機械学習により構築された学習モデルを記憶する記憶部と、学習モデルを用いて、センサ出力から着席者の姿勢又は着席者の姿勢遷移を推定する推定部と、を有する。【選択図】図1
