Microsoft patent features 'hinge gestures,' curved-display correction for rumored 'Andromeda' PC
New patent applications by Microsoft show what their rumored foldable Surface could look like and do.
It's an open secret that Microsoft's engineers are obsessed with hinges (so much so those who work in the area are called "hingineers"), which makes these new patent applications unsurprising. Still, the focus on a foldable mobile device that happens to fit in your hands – and the ramifications of this interaction model – does give hints at what is believed to be Project Andromeda.
The patent applications both published on April 26, 2018 (and spotted by @stevenwlack) address two major concerns for a device with a foldable display:
- Input based on interactions with a physical hinge
- How light and images are corrected where the display curves
The first patent application US 2018/0113520 A1 shows in its accompanying images a now-familiar design: a mobile device that comfortably fits in both hands, but folds in the center of the display.
The question Microsoft is attempting to answer is how holding a device with two hands (both displays) versus closed – and the degree of the angles – affect usage models with the OS. Or, as the application puts it:
Microsoft then proposes what could be summarized as "hinge gestures" where the hardware and operating system are aware of the hinge, orientation, how the user is holding it and more. Again, from the application of the patent:
The reason Microsoft would want such a system is to make the OS radically smarter: "Use of an approximate hinge angle to switch between two or more discrete views of content or UI on one or more connected display screens, such as switching between different views of a dataset or showing/hiding chrome elements."
That language sounds a lot like Microsoft's Cshell – the adaptable UI that is the extreme version of Continuum where the OS adjusts its content based on the screen size, device, orientation and more.
The second application is a little less exciting, but still very important. US Patent application US 2018/0113241 A1, also published on April 26, 2018, is concerned with how images on a display where it curves are viewed.
More specifically, whereas displays are now very good at presenting accurate information when flat how that content is displayed when it begins to curve can be problematic (think of astigmatism for eyesight and the need for corrective lenses).
The patent application uses a lot of jargon, but the important part is here:
Microsoft here is concerned with making the OS and content look the same as the flat portion of the display compared to where it curves. Again, that may seem trivial, but it is a complicated problem that needs to be solved by an "image-correcting layer" to give the illusion that the image is not curving.
My quick analysis
Both patents continue a massive series of applications and attempts by Microsoft to invent new technology around devices that fold in the middle of the display.
Project Andromeda is both a hardware project and software one with the latter focused on Windows Core OS as a stripped down, mobile version of full Windows 10 made for future handheld devices.
Since last year, we have been calling Andromeda the spiritual successor to the fabled Microsoft Courier project from 2010. While not a "Surface phone" the device is meant to kick off another form factor for computers that merge the best of smartphones with the best of tablet PCs for a more modern world. While the device is question can make phone calls it likely won't be positioned as a phone, but rather a digital Moleskin notebook.
It is clear from both patent applications – especially the first one – exactly the type of computer Microsoft has in mind. Think of a small Surface PC that folds in half with a light, modern OS that adjusts content based on its position.
Apps that have dual screen support to simulate a digital notebook are one application, whereas other times the user may want a full screen, e.g., for the OS. How the device handles the OS when going to "one" screen or two is something that needs to be solved if the experience is to be smooth and natural.
Whether or not Project Andromeda sees the light of day remains to be seen, but the sheer amount of research, engineering, and even paperwork around the concept is becoming daunting.
Despite Microsoft having a few Surface devices under its belts Project Andromeda seems the most complicated with more patent applications (e.g. this one, this one, this one, and definitely this one) filed for its underlying technology than any other Surface we have seen to date.
Hopefully, we'll hear more about this device this year. We still hear rumors of a fall release for Andromeda, which coincides with Windows 10 "Redstone 5". That next version of the OS is now focusing on cellular connections and a new radio stack, which is likely not a coincidence.

However, if the size of Andromeda is close to or smaller than Switch without controller, that would be good enough.
Sometimes I dont, but every once in a while its just more natural and easier to reach up and touch my surface book screen than to use the trackpad.
Occasionally I borrow my daughters Mac and it frustrates the #$!@ out of me that the screen doesn't respond to my touch. Over priced piece of #$@!
What Microsoft is doing, is to bring fresh new ideas for mediocrity of smartphone market where nobody is innovating anymore.
But with Microsoft's foldable device, I might take my retirement savings and give away my money on this amazing idea of a foldable device.
of seeing Microsoft Andromeda device patents. Microsoft it's time to bring it to the market Place. I think this wont occur unfortunately untill Restone 5's Update comes this fall and the Qualcomm Snapdragon 845 ARM CPU is available in enough quantities to be installed on Andromeda devices. I sure hope it's worth the wait. I would like to work with a device that's bigger than a smart phone but not as big as a 10 inch or larger Tablet.
The extra screen size will give the WOW factor and hopefully the power to run an emulator to support Android apps if required by the user.
It may morph into some mobile xbox handheld device plus business filofax type of thing that runs X86 apps.
