In an information processing method, a computer acquires a sleep state of a person existing in space, acquires detection data output from a sensor that detects entry of an object into the space, performs a first determination to determine whether or not the sleep state changes to awakening within a predetermined time from a time point at which the object is estimated to enter the space based on the sleep state and the detection data, generates, in association with the sleep state before the time point, awakening information for determining possibility that the person is awakened by entry of the object in a case where the person is in the sleep state before the time point of entry based on a result of the first determination, and presents the awakening information associated with the sleep state via a presentation device.
