    Abstract: Methods and apparatus for providing a dynamic interface, for example, a keypad on a touch screen. When the touch screen displays a keypad, the appearance of the keypad is randomly generated. In an embodiment, consecutive keypads can differ with respect to any combination of the size of the keys, the shape of the keys, the spacing between the keys and the position of the keypad on the screen. Additionally, at least some part of a generated keypad appearance can be determined from a previous user's input.
