According to the present invention, a camera (26) photographs users (U1, U2, U3). An indoor environment information sensor (13) detects indoor environment information about the environment in a room (r1) that the users (U1, U2, U3) are in. On the basis of an image of the users (U1, U2, U3) that has been captured by the camera (26) and of the indoor environment information detected by the indoor environment information sensor (13), an estimation unit (66) estimates how drowsy the users (U1, U2, U3) are.
照相机(26)拍摄用户(U1、U2、U3)。室内环境信息传感器(13)检测与用户(U1、U2、U3)所在的室内(r1)环境相关的室内环境信息。推测部(66)根据照相机(26)已拍摄到的用户(U1、U2、U3)的图像以及室内环境信息传感器(13)已检测出的室内环境信息,推测用户(U1、U2、U3)的睡意状态。
