Samsung Patent Describes How To Unlock Your Phone By Drawing

The Galaxy smartphone maker has filed for a U.S. patent to unlock mobile devices when users touch-and-drag drawings that have at least one intersection point.

The US 20140066017 A1 patent was filed with the US Patent & Trademark Office Aug 29, 2013 but was published online Mar 6, 2014. The "Method of unlocking mobile terminal, and the mobile terminal" title is related to a method to conveniently unlock a mobile device with a "touch-and-drag operation" on the device's touch screen. The method includes tracking the touch-and-drag trajectory, where one or more intersections occur, to release a lock mode.

That 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.

It also doesn't matter what form or shape the figure should take, as long as there's at least one intersection point. And users will be able to customize the drawings to turn on specific apps.

The patent application reads "The hot key function includes various applications or functions that are provided by the mobile terminal, and a specific application or function corresponding to the number of intersections is executed. The specific application or function includes a camera, a phone number list, a message, a call, and various applications or functions that are provided by the mobile terminal.

"The user may freely touch a touchscreen since there is no limitation in terms of size, location, and pattern of a touch input, and since a standby screen is displayed or a specific application is quickly executed according to the number of intersections of a closed surface."
