A user interface for an electronic device and method for managing a state of a user interface between a locked state and an unlocked state are provided. The user interface has a touch sensitive display having a display surface, the touch sensitive display being adapted for presenting to a user at a respective position at least one display element along the display surface. The touch sensitive display is further adapted for receiving from the user, a user interaction with the touch sensitive display at a location along the display surface including a display element selection and a defined path. The user interface further includes a controller, where the controller includes a user interface state module having an unlocked state and a locked state adapted for selectively enabling and disabling at least a portion of the user interface. The controller further includes a state change module adapted for switching the state of the user interface state module between the locked state and the unlocked state. The state change module switches the state of the user interface module from the locked state to the unlocked state when the state change module detects each of the at least one display elements in respective unlock position for the corresponding one of the at least one display elements. The controller still further includes a lock state interface module including a path analyzer having an avoid area comparator, which determines whether a gesture attempting to transition a display element from a lock position to its respective unlock position interacts with the one or more avoid areas, and if so returning the display element to its preselection position.
