7. The electronic device of claim 6 , wherein

the circuitry is configured to control the communication interface to transmit, as the message, a request for information in the case that it is determined that the electronic device is worn on a part of a human body after predetermined time has elapsed from when the electronic device was removed from a part of a human body.

8. The electronic device of claim 6 , wherein the circuitry is configured to:

determine a current time; and

select the message to be transmitted to the another device based on the determined current time.

9. The electronic device of claim 6 , wherein the circuitry is configured to:

determine a current time; and

select the message, from a plurality of different messages requesting different types of content, to be transmitted to the another device based on the determined current time.

10. The electronic device of claim 1 , wherein

the circuitry is configured to not reproduce the content in a case that it is determined that the electronic device is worn on a part of a human body before a predetermined time has elapsed from when the electronic device was removed from a part of a human body.

11. The electronic device of claim 1 , wherein

the wireless communication interface is a Bluetooth communication interface.

12. The electronic device of claim 1 , further comprising:

the sensor configured to detect whether the electronic device is worn on a part of a human body.

13. The electronic device of claim 1 , further comprising:

a user interface, wherein

the circuitry is configured to

detect a plurality of operation modes of the user interface; and

control the communication interface to transmit an operation signal according to the detected operation mode to the another device.

14. The electronic device of claim 1 , wherein

the circuitry is configured to control the wireless communication interface to transmit, to the another device, an instruction that causes the another device to perform a process that varies based on whether the information processing device is worn on a part of a human body.

15. The electronic device of claim 1 , wherein

the electronic device is an earphone configured to be worn on a user's ear.

16. An electronic device comprising:

a wireless communication interface configured to communicate with another device; and

circuitry configured to

determine, based on an output of a sensor, whether the electronic device is worn on a part of a human body;

identify a time duration between a last time that the electronic device was removed from a part of a human body and a time that it is determined that the electronic device is worn on the part of the human body based on the output of the sensor; and

control reproduction of content provided by the another device via the wireless communication interface based on the time duration.

17. The electronic device of claim 16 , wherein

the circuitry is configured to reproduce content provided by the another device via the wireless communication interface in a case that the time duration exceeds a predetermined threshold value.

18. The electronic device of claim 16 , wherein

the circuitry is configured to not reproduce the content provided by the another device via the wireless communication interface in a case that the time duration is less than a predetermined threshold value.

19. The electronic device of claim 16 , wherein

the electronic device is an earphone configured to be worn on a user's ear,

the wireless communication interface is a Bluetooth communication interface,

the another device is a mobile phone, and
