Abstract
A method, system, and device for controlling a mobile device with a touch screen are disclosed. According to one embodiment, the mobile terminal includes a touch screen and a controller configured to display a uniform image of a first enclosure and an unlock image of a second enclosure bounded by the uniform image of the first enclosure on the touch screen in response to detection of a contact on the touch screen while the mobile terminal is in a lock state. The controller is further configured to enlarge the unlock image of the second enclosure in accordance with movement of the contact away from an initial position of the contact while the contact on the touch screen is maintained, and to unlock the mobile terminal in response to a release of the contact when the unlock image of the second enclosure is enlarged to reach or exceed the uniform image of the first enclosure.
