Abstract
Aspects of the present invention enable a storage device (e.g., a recordable book, toy, computing device) to be controlled with a single control button that performs multiple functions. Different interactions with the button produce a different control input. In one aspect, the storage device is an audio recording device that can record, lock, unlock, transfer to a separate storage device, or play back one or more audio recordings. These five functions (i.e., recording, locking, unlocking, transferring, and playing back) are initiated or facilitated by depressing a single button located on the audio storage device for different lengths of time or in different patterns. Audio recordings may be played in response to user interactions with the button to help the user interact with the button properly and warn the user of action that is about to be taken.
