  • Patent number: 9053709
    Abstract: The present invention relates to a control device, a control method, and a program capable of improving operability with a simpler configuration. A reproducing apparatus 11 which reproduces sound such as music includes earphones 21 which are worn by a user on the ears and a body 22. A sound pickup unit 31 collects sounds around the reproducing apparatus 11, and a determination unit 34 extracts future amounts from the collected sound and determines whether the sound corresponds to an operation sound generated when the sound pickup unit 31 is directly tapped by the user. A controller 35 executes a process in accordance with a result of the determination performed by the determination unit 34.
