Nokia's no stranger
to the patent application process
here in the United States, and while we've certainly seen some strange ones
emanating from its R&D labs, this one looks like something that should be implemented on the double. Explained as a "user interface for controlling an electronic device," the multitouch solution would essentially allow you to pinch, zoom and rotate objects as usual, but it would also employ an array of pressure sensors in order to give your motions a sense of severity. If executed properly, one could theoretically envision the use of a strong push to simulate a double tap (for example), or as a means to activate a secondary function that generally requires another button press or the use of a 'Function' key. Hit the read link for all the mumbo jumbo, but be sure to keep your expectations within check. Or not.
