Google granted patent for Android pattern unlock
Google has been granted a patent for the unlock pattern that comes with many Android devices, including the first ever handset, the T-Mobile G1. If you’re not familiar with the pattern we’re referring to, it’s a 3×3 dot screen which can be customized to a nearly infinite number of possibilities. Want to draw a big square? Go for it! Ours looks more like a lightning bolt with an arm.
Whereas Apple users get the slide screen, Android comes with a variety of unlock patterns which are often determined by the handset maker. Those of you with an HTC Sense handset have likely never had to use the pattern screen, instead getting a more rich experience.
A lock screen view is displayed on the mobile device to prevent unauthorized and inadvertent access to the mobile device’s data. While the mobile device is locked, a touch gesture having a pre-defined shape is detected on a touch screen of the mobile device independently of the initial position of the touch gesture on the touch screen. - Touch Gesture Actions From A Device’s Lock Screen
Keeping with HTC Sense, the patent also refers to some of the customization that various OEMs might employ – silence, launch to email, etc.
In response to detection of the touch gesture, a particular action is executed on the mobile device while the mobile device stays locked. The particular action determined according to the pre-defined shape. In this way, detection of the touch gesture causes the particular action to execute while keeping the mobile device locked.
