HTC Files Patents for Screen-Locking Capabilities
With the iPhone and other similar touchscreen phones popping up all over the place, each with their own way of unlocking the screen after it’s been in your pocket/purse/etc. it’s always interesting to see new patents filed about this very process.
This time we see patents being filed from HTC; 3 of them, to be precise. But all 3 have something to do with unlocking screens that have been turned off. It’s quite possible that any of these three could make it into a new build of the Sense or TouchFLO UI somewhere down the road.
WMPowerUser suggests these will be implemented in Sense UI and will be sooner rather than later.
Underneath we have provided a pic of one of the patents as well as abstracts for each.
Here are the patents:
1. Unlock the screen by swiping your finger down vertically.
A mobile electronic device, a method for entering a screen lock state and a recording medium thereof are provided. In the present method, an input signal is received through a touch panel of the mobile electronic device. Then, a movement track of the input signal is obtained if a starting point of the input signal is located in a non-display area of the touch panel, and a vertical displacement of the input signal is calculated if the movement track contains a specific direction. Finally, a screen lock frame is dragged and displayed, and the mobile electronic device is switched to the screen lock state if the displacement reaches a predetermined value. Thereby, an intuitional way for locking the screen is provided, and accordingly, the convenience in operating the mobile electronic device is improved.
2. Method to change wallpaper on the lock screen, without actually unlocking the screen to do so.
A method for switching wallpaper in screen lock state, a mobile electronic device thereof, and a storage medium thereof are provided. In the present method, an input signal is received by a touch screen when a mobile electronic device enters a screen lock state. Then, whether the input signal is located in a specific area of the touch screen is determined. A moving track of the input signal is detected if the input signal is located in the specific area. Finally, wallpaper of the screen lock state is switched according to the moving track. As a result, a user can switch wallpaper arbitrarily even if the mobile electronic device is in the screen lock state, so as to increase convenience of switching wallpaper.
3. The typical method of unlocking a screen.
A method for unlocking screen, a mobile electronic device using the same and a storage medium thereof are disclosed. First, at least two signal input areas on a touch screen of the mobile electronic device are defined. When an input signal is detected within at least one signal input areas, a moving range of a trajectory produced by the input signal is calculated. And the touch screen is unlocked when the moving range reaches the predetermined value. Thus, the present invention provides a user with more virtual manner to close the screen locking function so as to promote the usage convenience of the mobile electronic device.
Okay, so the first two I can see being patented because I haven’t actually seen them implemented on any other touchscreen device. But the third one, unless I’m mistaken, sounds exactly like the usual method for unlocking screens. If that’s true, then I would be very surprised if a patent doesn’t already exist by somebody somewhere.
