Abstract
An information processing apparatus includes circuitry that acquires a measured temperature of a target area from a measuring device, detects whether the measured temperature changes during a predetermined time period, determines whether a human exists in the target area based on the measured temperature and the detection result indicating whether the measured temperature changes during the predetermined time period, measures a duration of time in which the determination result indicating that the human exists in the target area and the detection result indicating that there is no temperature change are kept generated, and determines that there is no human in the target area even when the determination result indicates that the human exists, if the measured duration of time reaches a certain time period, the certain time period being modifiable based on history information indicating a previously generated determination result indicating whether the human exits in the target area.
