A user interface for an electronic device and method for managing a state of a user interface between a lock state and an unlock 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. The user interface further includes a controller, where the controller includes a user interface state module having an unlock state and a lock 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 lock state and the unlock state. The state change module switches the state of the user interface module from the lock state to the unlock 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, said lock state interface module being adapted to detect a received user interaction that is initiated with a selection of one of the at least one display element having a variable start zone. The lock state interface module includes a start zone movement module where prior to the selection of the display element by the user, the variable start zone of the display element moves along the display surface as a function of time, such that the variable start zone has a first location at a first point in time, and the variable start zone has a second location at a second point in time, which is different than the first location.
