Abstract
Abstract The present invention discloses a data input device including a touch screen. The touch screen has two information display levels. A first level displays a virtual alphanumeric keypad which allows a user to input textual data by simply touching the screen. The second level displays the input textual data. The touch screen allows for simultaneous display of both the virtual keypad and the input data by representing the virtual keypad and underlying textual data by different colors, character sizes, styles, fonts, intensities, etc.
