Abstract
A sleep warning apparatus includes a stimulation generating portion, a reaction detecting portion, a warning determining portion, and a warning generating portion. The stimulation generating portion generates stimulation to a person before a warning is given to the person. The stimulation is used to take reaction of the person. The reaction detecting portion detects the reaction of the person to the stimulation when the stimulation generated by the stimulation generating portion is given to the person. The warning determining portion determines whether or not the warning is required to be given to the person depending on whether or not the reaction detecting portion detects the reaction of the person to the stimulation. The warning generating portion gives the warning to the person when the warning determining portion determines that the warning is required to be given to the person.
