Fluent Design

There are quite a few changes coming up with the Fall Creators Update, but none are going to be more noticeable than the Fluent Design being introduced. The look and feel of Windows has evolved significantly over the years, but Microsoft made a substantial change to a more modern design (*cough* Metro *cough) which really moved away from the skeuomorphic look of the physical world into a flatter, sleeker look with Windows 8. Not everyone appreciated the extreme flat design though, and Microsoft has evolved the look especially with Windows 10 which did move back to a few of the layering effects with some drop shadows coming back, and a few other design tweaks, but the overall design language for Windows and the apps kept a similar feel to Windows 8.

With Fluent Design, Microsoft is making as big of a change to the design language as they did when they moved from Windows 7 to Windows 8. That may sound scary to some, but they felt it was important to tackle this now. When the modern look came along, Microsoft was trying to address new device types with touch as a first-class citizen, and although they arguably went too far with touch in Windows 8, Windows 10 has a great balance for touch while keeping the existing keyboard, mouse, or trackpad input methods as equals with touch. But the gamut of devices has grown again. The amount of computing devices has grown from mainly 2D display based products to now include both 3D in mixed reality, along with 0D devices like IoT, body-worn devices, and voice-activated devices like Amazon’s Echo or the just announced Harman Kardon Invoke voice-activated speaker powered by Cortana. Display based devices work with more traditional input methods like touch, keyboard, mouse, and pen, but mixed reality and devices without displays need to work with voice, gaze, and motion, and Fluent Design is going to attempt to allow interaction from all these input methods.

Fluent Design is based on five ideas: light, depth, motion, material, and scale. Although discussion is required, Microsoft did do a promotional video on the new system.

The light is going to be very useful across multiple input types, with mixed reality likely seeing the most benefit of a light-based gaze input. Right now, Windows 10 offers a highlight for selected items in the Start Menu, as an example, but with Fluent Design the experience will be much more immersive. There are some great use cases for light to assist with selection, especially in a grid-based selection like when you sort by alphabet.

Windows 8 went extreme on the flat design look, and Microsoft has pulled back somewhat over the last several releases on this, but with Fluent Design, depth is once again being used as not only an accent, but also for layering for applications so the actionable information is layered to the top. The depth is much more than just drop shadows, with parallax scrolling available for backgrounds, and more.

Motion is going to be highly leveraged for moving into and out of applications, as well as inside of applications, in order to provide some perspective on where you are. Perhaps as you drill into an app, you’ll see inward movement, but then as you go back, the app will show outward movement, so there is an instant connection to the user on where they are going. Microsoft is also looking to use movement to improve the transitions between different applications, and within Windows itself. They need to be careful they don’t add too much delay, or allow adjustment for the end user, but it should help with some of the jarring experiences seen now.

Material is going to be a large part of Fluent Design, and although this is Aero 2.0, it’s also much more than just Aero effects of blurring and glass type looks. Instead of just background colors and blur, they will be doing multiple layers with Gaussian blur, exclusion blend, color and tint overlays, and tiled noise texture. The acrylic material look can be used for layering in addition to depth, and the materials are going to add a lot more texture to the look of Windows.

Scale is becoming much more important as well, when you consider how Windows can be adapted to so many different device types. Fluent Design can be used to scale an app all the way from a 10-foot UI for the Xbox, down to a mobile device or tablet.

Fluent Design is not going to be just a Fall Creators Update feature either. This is just the first wave of an overhaul which will be ongoing for some time. As with anything in Windows now, with a relatively fast update cadence, it makes sense to release these types of updates in waves for several reasons. You don’t want to overwhelm people with massive changes, so by doing it in waves you can allow them to get used to the new changes in smaller bites. Also, you can use the wave approach to fine tune and adjust the idea through real world use. Perhaps some of the acrylic blur is going to cause contrast issue with text, so it may have to be adjusted, as an example.

Although to some it may seem that this is just eye candy, it’s important to keep the interface fresh and modern looking. It’s very easy to fall into the trap of keeping something that works ok just because people are familiar with it, but not using the interface as something that can be adjusted and improved over time.

Microsoft also made the point that Fluent Design can have effects turn on or off on the fly based on events. For instance, when running an app in a full-screen view, it may not make sense to have some of the background coming through. Effects can also be disabled based on the system power state, so if you need to eke out the maximum battery life on a long stint away from power, it may not make sense to have some of these effects available.

The key point though is that Microsoft is using this UI overhaul as a way to make improvements in device types that are not just typical laptops or desktops. The light and gaze features coming should make mixed reality control much easier, and input with keyboard, mouse, trackpad, pen, touch, voice, sight, and gesture, all need to be addressed. So far Microsoft has shown off several apps that have already been updated to the new design language, and it looks great. This is certainly going to be one of the key features coming in the Fall Creators Update.

    I'd guess you're not using Enterprise. The "test this app" experience might be MS's way of steering businesses towards Enterprise rather than Pro. Reply

    I suspect the downloads are done by some third-party software. Reply

    It's actually something MS included as "a feature". The content delivery manager with the pre-installed apps option. You can disable this in registry or local policy.

    As far as I know it comes in the Pro versions although some older MSDN Windows Enterprise ISOs came with it enables. I guess MS received enough feedback from enterprises to cut the crap so now they just try it on regular customers.

    I would love it if all my apps could be fetched through the store. The problem is most of them are NOT UWP, and created by small developers (utilities and such). Hopefully MS has made it really easy to get apps into the store, because otherwise most of my apps will never be there. Reply

    I probable have 4-5 programmes beyond Chrome and Office, all but one open source, and none came through the app store. The App Store itself is mainly full of junk. Reply

    Yeah I know it is. I just wish it weren't. :) I actually find Chocolatey to be pretty useful for open source stuff, although I worry a lot about someone uploading a trojan package since it's much newer and less popular than Ubuntu repository for instance. Reply

    The Linux subsystem is truly amazing stuff, and I already find it useful. Unfortunately there is no GPU-acceleration which is a buzzkill for me. Trying to learn machine learning techniques on Windows is really painful since the library support is not so great. Reply

    I really hope they follow through Fluent design language,Wide Color gamut, and HDR support.
    I really don't want my 2017 computer run a UI which looks horrible

    I see no point in messing with Linux inside of Windows when I can simply use Linux atop bare metal and get the distro I want the way I prefer to use it. As well, I don't have to deal with always-on, Google-levels-of-creepy Cortana lurking and listening or non-removable OneDrive. The visual activity history is nice, but I'd hope it can be totally disabled. Knowing how MS works these days, probably not and it's likely part of their data mining efforts as they play catchup with Alphabet and others. Reply
