Classification: CPC G | IPC G

Claim 0:
1. A notification system, comprising:
a proximity sensor that detects an approach of an object to a predetermined area;
an image sensor that captures an image;
an ultrasonic irradiation device that remotely irradiates a portion of a body of a person with an ultrasonic wave that can generate a tactile sensation; and
a notification device equipped with a proximity sensor control unit, an image sensor control unit, a person detection unit, and an ultrasonic irradiation control unit;
wherein the proximity sensor control unit acquires distance information to the object from the proximity sensor;
the image sensor control unit acquires image information of the object from the image sensor;
when the object approaching the predetermined area within a predetermined range is a person, the person detection unit detects a portion of a body of the person from the distance information and the image information;
wherein at least one of the proximity sensor and the image sensor, and the ultrasonic irradiation device respectively have three or more markers on a reference surface;
a positional relationship between the ultrasonic irradiation device and at least one of the proximity sensor and the image sensor can be determined from an image obtained by photographing three or more markers on each of the reference surfaces; and
the ultrasonic irradiation control unit causes the ultrasonic irradiation device to irradiate the portion of the body of the person detected by the person detection unit with the ultrasonic wave according to the positional relationship between the ultrasonic irradiation device and at least one of the proximity sensor and the image sensor.
