The patent also shows which combination of gestures will be used for certain apps. In the email app, for example squeeze the top of the phone to scroll up. Squeeze the bottom of the phone to scroll down. While using the browser, squeeze the phone to move ahead a page. Splay the device to go back a page. Scrolling up and down requires the same gestures as on the email app.
There is no guarantee that Google will ever employ this technology, but it is something to think about. Soon, we might be applying pressure to our phone instead of using a finger to scroll and to move between web pages.
Thank you Anoymous Tipster!
