20. The device of claim 19 wherein the distinct mode of touch is a two finger touch and wherein the normal mode of touch is a single finger touch.

21. The device of claim 1 wherein the instructions are further configured to present a transformed element on the display in response to a user interaction with the touch interface, wherein the transformed element interacts with the touch interface in a different mode of operation than a mode of operation of the corresponding active element prior to its transformation.

22. The device of claim 21 wherein the transformed element appears magnified on the visual display compared to the active element prior to transformation into the transformed active element.

23. The device of claim 22 wherein the instructions are configured to control a degree of magnification of the transformed element according to a mode of touch on the touch interface.

24. The device of claim 21 wherein the instructions further comprise an instruction configured to revert the transformed element to a form the active element had prior to being transformed into the transformed element in response to a signal from the touch interface or after an interaction with the transformed element is completed.
