Another part of the patent filing deals with Convenience-Based Unlocking which could be as simple as dragging the icon of a phone contact from the top of the display to an unlocking icon at the bottom. Google also showed a new interface for unlocking future phones. It is a wheel that the user moves to a specific application, for example email. Before the device is totally unlocked, certain actions could take place like refreshing the inbox. Once the complete unlocking process is done and the device is unlocked, the user's email interface would appear, all ready to go. The user could program the device to head anywhere on the phone or tablet after it is unlocked, such as a social networking app. Verbal directions could also be used to unlock the device.
It all seems so complex and convoluted, but that is the price that smartphone users must pay in a litigious world.
