PROBLEM TO BE SOLVED: To provide a technique to estimate the sleep mode of a child.SOLUTION: A sleep inspection device comprises a pressure sensor, an acquisition unit S110 and S170, a generation unit S140 and S150, and an estimation unit S180 to S210. On the basis of the distribution of the body pressures of a subject acquired by the acquisition unit, the generation unit generates body motion data representing the progress of the body motion of the subject S140 and S150. On the basis of the body motion data generated by the generation unit, the estimation unit estimates the sleep mode of the subject S180 to S210.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】子供の睡眠態様を推定可能とする技術の提供。【解決手段】睡眠検査装置は、感圧センサと、取得部S110,S170と、生成部S140,S150と、推定部S180~S210とを備える。生成部は、取得部で取得した被験者の体圧の分布に基づいて、当該被験者の体動の推移を表す体動データを生成するS140,S150。推定部は、生成部で生成された体動データに基づいて、当該被験者の睡眠態様を推定するS180~S210。【選択図】図2
