An information processing device includes an acquisition unit, an identification unit and an emotion estimation unit. The acquisition unit acquires input information as information regarding a user in a certain situation. The identification unit identifies an object to which the user is paying attention and the user's appearance when the user is paying attention to the object based on the input information. The emotion estimation unit estimates emotion of the user based on object information indicating the identified object, appearance information indicating the identified appearance, and a predetermined method of estimating the emotion.

A course prediction device () includes a blind spot calculation unit () and a prediction unit (). The blind spot calculation unit () acquires a sensing result sequentially from a sensor which is arranged in a mobile object and which detects whether an object exists, and calculates, based on sensor information, a blind spot area expressing such an area that an object existing therein cannot be detected by the sensor. The blind spot calculation unit () also detects an object entering the blind spot area based on the sensor information. The prediction unit () predicts a course in the blind spot area of the detected object based on the sensing result.

An acquisition unit of a falling object detection apparatus installed and used in a first vehicle acquires a depth image of a second vehicle, on which a load is mounted and which is traveling in front of the first vehicle, and of the area around the second vehicle. A determination unit of the falling object detection apparatus determines whether the load has not made a movement different from that of the second vehicle, using the depth image acquired by the acquisition unit. A detection unit of the falling object detection apparatus detects a fall of the load based on a result of determination by the determination unit.

A reception unit receives, with an ultrasonic sensor, received signals including a reflected wave obtained when an acoustic signal emitted from a mobile body is reflected by an object. A disturbance judgment unit judges whether a jamming attack in which a jamming signal is transmitted from outside is being made, on the basis of the received signals. An object detection unit detects an object in surroundings of the mobile body on the basis of the received signals if it is judged that no attack is being made and does not perform object detection if it is judged that an attack is being made.
