BlackBerry was awarded a patent recently for what seems to be the touch sensitive keyboard we heard about coming to the Windermere codename device. The keyboard is intended to be a touch sensitive part of the device which is very innovative. BBNews.pl spotted this new patent for a physical keyboard that somehow overlays a touch sensitive display. That means that each key has two functions one for touch and one for pushing. That means you can have both touch events and physical button push events.
Here is how BlackBerry describes it in the patent:
A physical keyboard having a plurality of individual keys temporarily overlays a touch-sensitive display. Each individual key selectively provides either of a first level of capacitive coupling and a second, different level of capacitive coupling to the touch-sensitive display. By one approach the key provides that first level of capacitive coupling to the touch-sensitive display when a user asserts the key (for example, by pressing upon the key) to thereby communicate to the touch-sensitive display a selection of that individual key. The key can provide that second level of capacitive coupling when a user touches, but does not assert, the individual key. So configured, this second level of capacitive coupling serves to communicate to the touch-sensitive display an input instruction other than a selection of that individual key.
