Abstract
A drowsiness prediction device includes: a carbon dioxide concentration detector that detects the concentration of carbon dioxide in a compartment; an oxygen saturation detector that detects oxygen saturation in the body of a driver present in the compartment; a predictor that predicts, according to the concentration of carbon dioxide and the oxygen saturation detected, a level of drowsiness that the driver would feel after the detection of the concentration of carbon dioxide and the oxygen saturation; and an outputter that outputs information indicating the predicted level of drowsiness.
