Samsung has filed a patent for a new feature that will allow a device to be unlocked by drawing a figure on the screen with at least one intersection point.
According to patent application US20140066017 filed over the weekend with the US Patent & Trademark Office, the Korean smartphone maker wants first dips at a "touch-and-drag operation" to unlock a mobile terminal while the device is in lock mode. The method includes tracking the touch-and-drag trajectory, where one or more intersections occur, to release a lock mode.
That effectively means the feature can be used while the device's display is off, so users don't have to hit the power or home button to turn on the display just to use the feature.
