Abstract

An electronic device, a controlling method thereof, and a computer program product are provided. In the present method, a part of inner area of an unlock ring is displayed while the electronic device is in a user-interface lock state. While a user input applied to the unlock ring on or near a touch screen of the electronic device is detected, the unlock ring is moved in accordance with the user input. The electronic device is switched to a user-interface unlock state if the unlock ring is moved to make a predetermined ratio of the inner area of the unlock ring cross a predetermined edge, or maintained in the use-interface lock state if the unlock ring is not moved to make the predetermined ratio of the inner area of the unlock ring cross the predetermined edge.

Description

technical field [0001] The present invention relates to electronic devices with touch screens. More particularly, the present invention relates to a method to unlock a touch screen and an electronic device using the method. Background technique [0002] With the development of touch sensitive input devices such as touch screens, manufacturers of electronic devices such as notebook computers, mobile phones or mobile multimedia players generally use touch screens instead of conventional keyboards to provide more convenient A user interface allows a user to interact with a device.
