Abstract
Embodiments of the present invention relate to methods of enabling a portable electronic device with a transparent, flexible, removable, pushbutton overlay that lays over at least a portion of the graphic touch-screen display on the portable electronic device. The pushbuttons in the overlay are designed to transmit finger pressure to the pressure-sensitive touch-screen display and also to provide a natural feeling tactile feedback to the user. At the same time, being transparent, the overlay allows the user to view the contents of the Graphical User Interface that are presented directly beneath the buttons and allow the user to respond to those contents. The buttons are, in some embodiments, enabled as magnifying lenses in order to better present the GUI contents.
