So apple now has the patent for any slide gesture to unlock a device. This will most likely entail more lawsuits against anyone using a slide to unlock system on their phones or tablets. Im a fan of both but this seems like its taking it too far. Apple wasnt the 1st one to use the slide to unlock. Windows CE was the 1st to use it but never patented it.
here is the actual patent.
A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display. The device is unlocked if contact with the display corresponds to a predefined gesture for unlocking the device. The device displays one or more unlock images with respect to which the predefined gesture is to be performed in order to unlock the device. The performance of the predefined gesture with respect to the unlock image may include moving the unlock image to a predefined location and/or moving the unlock image along a predefined path. The device may also display visual cues of the predefined gesture on the touch screen to remind a user of the gesture. — Patent 8,046,721
