Abstract: A communication circuit communicates with a right earphone worn on a right ear of a user and a left earphone worn on a left ear of the user to receive a first output signal generated by a first motion sensor provided in the right earphone and a second output signal generated by a second motion sensor provided in the left earphone. A detector detects whether a third party has approached the user based on a difference value between the first output signal and the second output signal received by the communication circuit. A notification unit notifies the user that the third party has approached the user when the detector detects that the third party has approached the user.

Abstract: An attendance management system includes a management device configured to manage attendance of a user and one earphone capable of performing a wireless communication with the management device, wherein the earphone is capable of detecting whether the earphone is mounted on the user and transmitting a result of the detection to the management device, and the management device determines that the user is at work when it is detected that a use state of the earphone is a predetermined state in which the earphone is communicably connected to the management device and mounted on the user.

Abstract: An information providing apparatus according to an embodiment includes: notification reception means for receiving a notification indicating that provision of information about a captured video image of a dashboard camera to a user is permitted, the dashboard camera being mounted on a vehicle; information acquisition means for acquiring the information about the captured video image of the dashboard camera, provision of the captured video image to the user having been permitted; information output means for providing, to the user who requests provision of the information about the captured video image acquired by the information acquisition means, the information about the captured video image; and payment means for paying a remuneration to an owner of the dashboard camera that has captured the video image, provision of the video image to the user having been permitted.

Abstract: A music reproduction program causes a computer to execute a graph setting step, a music selection step, and a reproduction step. The graph setting step sets a BPM graph showing the tempo of music file that a user listens to from the start of exercise to the end of exercise. The music selection step selects, when selecting the music file that the user listens to at any progress time in the distance or time after the start of the exercise, a music file having a BPM value within the predetermined range based on the BPM value at the progress time in the graph. The music selection step selects a music file having a BPM value within a predetermined range based on the BPM value set in the graph at the progress time point when reproduction of the entire music file is completed. The reproduction step reproduces the selected music file.

Abstract: An earphone includes a main body and an arm protruding outward in a radial direction of the main body and being capable of coming into contact with and biasing an inner wall of a pinna in a fitted state where the main body is fitted into a cavum concha of the pinna. The arm includes an easily-deformable portion which deforms more easily than other portions of the arm.
