摘要

PURPOSE: A user interface device and an image forming device and method using the same are provided to offer an effective visual feedback when an input window is activated. CONSTITUTION: A UI(User Interface) generator(110) generates the UI including the input window. When the input window is activated, a controller(120) enables the UI generator to change the size of the input window. When a character or a number is inputted in the input window or the mode for requiring the character/number input is entered, the controller makes the UI generator enlarge the size of the input window.
