Abstract: A mobile terminal includes: a peripheral interface having four terminals; an I2C interface; a first detection unit adapted to detect if an I2C device is inserted into the peripheral interface; and a first control unit adapted to, when the first detection unit detects there is an I2C device inserted into the peripheral interface, connect the I2C interface with the peripheral interface, such that the I2C interface is connected with the detected I2C device plugged in the peripheral interface. Accordingly, information exchange between mobile terminals and I2C devices can be achieved, thus adaptability of the mobile terminals can be expanded.

Abstract: A method of creating a music file comprising a plurality of tracks to be played simultaneously when the music file is played. The method includes creating a main melody track by selecting a respective pitch and duration of a plurality of notes, selecting a style of accompaniment music, retrieving accompaniment tracks for the selected style of accompaniment music from a memory, and combining the main melody track and the accompaniment tracks to create the music file.

Abstract: A method for playing a game based on events in a music file. The method includes providing a first user interface to enable a user to select a music file to be played in the game, the selected music file comprising a plurality of tracks to be played simultaneously when the selected music file is played; providing a second user interface to enable the user to select a track from the plurality of tracks in the selected music file; calculating event times associated with note events in the selected track, each note event corresponding to a note in the selected track; playing the selected music file; and determining if an appropriate key is pressed within a predetermined period of time before or after each note event of the selected track.
