Abstract

This watching system is provided with: a watching detection device that is provided with a cartilage conduction vibration source, a mastication sensor, and a bone conduction microphone and that is configured to be mounted on an ear such that the entry of the ear canal is opened; and a mobile phone or an in-home monitoring unit that receives watching detection signals from the mastication sensor and the bone conduction microphone by means of short-range communication and issues a notification to the outside. The watching detection device has an air conduction microphone and also functions as a hearing aid. When detection signals cannot be received from the mastication sensor or the bone conduction microphone for a predetermined time period, a notification is issued. The mobile phone and the in-home monitoring unit crosscheck watching detection information. The mobile phone also issues a notification of information indicating that there is no abnormality.

Claims

1. A watching detection device comprising:

a cartilage conduction vibration source configured to transmit vibration to cartilage of an ear; and

a watching detection sensor configured to detect watching information around the ear, wherein

the watching detection device is mountable to the ear with an entrance of an external auditory canal of the ear open.

2. The watching detection device according to claim 1, further comprising an air conduction microphone, wherein

the watching detection device functions as a hearing aid by vibrating the cartilage conduction vibration source in accordance with a voice signal picked up by the air conduction microphone.

3. The watching detection device according to claim 1, further comprising a short-range communication unit capable of communicating with a watching notification device, wherein

the watching detection device makes the cartilage conduction vibration source vibrate in accordance with a voice signal received from the watching notification device via the short-range communication unit.

4. The watching detection device according to claim 1, wherein the watching detection sensor is a masticatory movement sensor.

5. The watching detection device according to claim 4, wherein the masticatory movement sensor serves also as the cartilage conduction vibration source.

6. The watching detection device according to claim 1, wherein the watching detection sensor is a voice sensor.

7. The watching detection device according to claim 6, wherein the voice sensor is a bone conduction microphone.

8. The watching detection device according to claim 7, wherein the bone conduction microphone serves also as the cartilage conduction vibration source.

9. The watching detection device according to claim 7, further comprising an air conduction microphone for a hearing aid function, wherein

the air conduction microphone is turned off when the bone conduction microphone is used.

10. A watching system comprising;

the watching detection device according to claim 1; and

a watching notification device which receives watching information from the watching detection sensor via short-range communication with the watching detection device.

11. The watching system according to claim 10, wherein

the watching notification device issues a notification when it has been impossible to receive a detection signal from the watching detection sensor for a predetermined period of time.

12. The watching system according to claim 10, wherein

the watching notification device is a mobile phone, and a voice signal of a call partner received by the mobile phone is transmitted, via short-range communication, to the watching detection device to vibrate the cartilage conduction vibration source.
