A method for executing a menu in a mobile terminal is disclosed, wherein the method includes displaying a first icon on a touch screen of the mobile terminal, receiving a first multi touch gesture pattern on the first icon, and displaying at least one second icon upon recognition of the first multi-gesture pattern, the at least one second icon a sub icon of the first icon.

Method for executing menu in mobile terminal and mobile terminal using the same

A method to authenticate a device and service, and a system thereof, the authentication method including: requesting device authentication information from a device provider in order to receive a service from a service provider, distinct from the device provider, and receiving the device authentication information from the device provider, the device authentication information being used by the service provider to authenticate the device. Therefore, it is possible to perform a device authentication process and service authentication process more simply.

Method to authenticate device and service, and system thereof

An improved code changing method for an electronic musical instrument with an automatic accompaniment function allows a chord code change during a play in accordance with a tone of an musical instrument being used in the current accompaniment just before a new code representing a new chord is inputted for the next music play. The method includes judging the possibility of a slur processing by recognizing a tone being used in the automatic accompaniment when the new code information is inputted, performing the slur processing when the slur processing is judged to be possible, and performing a retriggering process or an automatic accompaniment by neglecting the new code information, when the slur processing is judged to be impossible.
