Abstract: Provided is an apparatus which can realize improvement of estimation accuracy of a satisfaction rate of a passenger of a vehicle with respect to a facility. A visit determining unit 42 determines whether or not a vehicle X has visited a facility. An emotion estimating unit 43 estimates emotion of one or more passengers of the vehicle X based on information relating to a state of the passengers. In the case where it is determined by the visit determining unit 42 that the vehicle X has visited the facility, the index value evaluating unit 44 evaluates an index value of a satisfaction rate of the passenger with respect to the facility based on the emotion of the passenger estimated by the emotion estimating unit 43 within a designated period of time since the vehicle X has left the facility.

Abstract: Provided is a device that identifies excitement in conversation among occupants of the vehicle and provides more appropriate information to the occupants at a better timing in accordance with a keyword which is expected to be of high interest for the occupants. A feeling estimation and determination unit estimates a feeling of an occupant in accordance with occupant state information acquired by an information acquisition unit. When the estimated feeling of the occupant corresponds to exaltation (excitement or the like), a target keyword designation unit designates a target keyword from keywords appearing during the past target time range and then outputs the target keyword. When a feeling of the occupant responding to the target keyword is positive, information associated with the target keyword is acquired and then output.

Abstract: A mobile unit control device is installed in a vehicle and includes a user detector that detects a user located within a first predetermined distance from the vehicle; a sight line detector that detects the direction of the sight line of the user detected by the user detector; and a response controller that performs interest response processing of, when the sight line detector detects that the sight line of the user is directed toward the vehicle, actuating an accessory (e.g., headlights, tail lamps) provided in the vehicle to change in a manner recognizable from outside the vehicle.

Abstract: An information acquiring portion acquires at least one of the user information, the in-vehicle condition information, and the traffic condition information of the vehicle. An approach necessity determining portion determines the necessity of the approaches to users based on a first information which is the acquired information. An approach content setting portion determines the contents of the approaches to the users. An approach acceptability estimating portion estimates the acceptability of the user to the communication based on a second information which is the acquired information. If the approach acceptability estimating portion estimates the necessity of the approaches, and the acceptability is larger than a threshold value, an approach implementing portion implements the approaches to the user according to the contents determined by the approach content setting portion.
