Last week the US Patent & Trademark Office published a patent application from Google that reveals a method of displaying a Graphic Keyboard. The twist to Google's invention is that it relates to providing mobile devices (smartphones & tablets) with backside sensors that act as keyboard keys for input on a virtual keyboard UI of the user's touch screen. The sensors are placed on both the right and left hand sides of the device as noted in our cover graphic above. Google states that there are front and backside sensors. Sensors 50A-D are frontal sensors and 50E-H are rear sensors. Google notes that "If the usage mode is a one-handed usage mode for a smartphone, a unitary graphical keyboard is displayed. If the usage mode is a two-handed usage mode for a tablet, a split graphical keyboard is displayed.
