Document Type and Number:
WIPO Patent Application WO/2020/179186
Kind Code:
A1
Abstract:
The present invention is provided with: a carbon dioxide gas concentration detection unit (21) that detects the carbon dioxide gas concentration in a cabin (12); an oxygen saturation detection unit (22) that detects the oxygen saturation in the body of a driver (11) present in the cabin (12); a prediction unit (24a) that predicts, according to the detected carbon dioxide gas concentration and the oxygen saturation, the level of sleepiness of the driver (11) after the carbon dioxide gas concentration and the oxygen saturation have been detected; and an output unit (24b) that outputs information indicating the predicted level of sleepiness.
