User Interface, Gestures, and Multitasking

by Anand Shimpi and Vivek Gowri

By now you should be fairly familiar with what Windows RT’s Start Screen looks like, at least from a distance. Power on a Windows RT tablet and you’ll be greeted by the new Windows UI. A big, horizontal canvas full of live tiles, a feature that first debuted in Windows Phone 7. Based on the Metro design language, and referred to as Metro UI for much of the development cycle, a trademark dispute has forced a name change to Modern UI. There’s no getting around it, there’s a definite learning curve to the interface. It doesn’t matter if you’re used to Windows 7, OS X, Android or iOS, the touch enabled Windows RT UI is going to feel different, and probably downright first.

If you put in the time to learn and get used to the interface however, it is easily among the best tablet user interfaces I’ve ever tried. Everything we despise Windows 8 for on the desktop makes perfect sense when viewed through tablet colored glasses.

As a recap, Windows RT (and Windows 8) relies on edge swipe gestures for much of the macro control over navigation. Full screen apps are left purposefully barren, with their focus primarily on content. The power is in what lies (virtually) beyond the edges of the screen. 

There’s no capacitive sensor array in the bezel of a Windows RT tablet, instead what the touch controller does is looks at starting position and velocity of gesture to determine whether your swipe originated on or off screen.

There are only four edge swipes you need to learn, one for each edge of the display. Swipe in from the left and you flip through apps, giving Microsoft the win for quickest task switcher among all tablets. By default a left edge swipe will switch to the previously used app, or if you just switched from that it’ll move to the next most-recently used app.

If you have a lot of apps to switch between simply left edge swipe in partially then swipe back out, revealing a more traditional task switcher (Windows + Tab also brings up this switcher). Of all of the Windows RT gestures the swipe in/out to bring up the task switcher is the most clunky, but it’s easy to get used to.

Go to the opposite side of the screen and right edge swipe in to reveal the charms bar. Here you get direct access to the software start button as well as a bunch of key tools, among them are search and settings. 

Although the appearance of the charms bar never changes, the function of these buttons do. Start always takes you to the start screen, but search and settings apply to the app currently in focus. I can’t stress how much of an advantage this is over iOS. If I need to play with an app setting on the iPad I either need to go home and to settings then find the app or hope the developer has stuck a tab somewhere in the app where I can play with options. 

Even better is the fact that I can toggle things like an app’s ability to run in the background and whether or not it’s allowed to give me notifications on the lock screen directly from the app settings page. The icing on the cake? Playing with settings never forces me out of the app itself, Windows RT simply devotes the right 1/4 of the screen to settings, leaving my app still in focus on the left. It’s perfect.

Also perfect? The ability to snap applications to the right or left edge of the screen and have a different window open in the remaining portion. This was called Metro Snap before use of the Metro name was discontinued, and it’s one of the more interesting features here. Snapping requires a screen with at least 1366 horizontal pixels, allocated as 1024 to the main window, 22 to the splitter, and 320 to the snapped application panel. It’s great for having an IM conversation or email inbox open on the side when writing, browsing, or doing essentially anything else. 

One of the biggest issues I’ve had with tablet multitasking to date is that it’s all been very focused on the active window, which makes doing things like messaging an absolute pain because you’re continually flipping between whatever you were doing (let’s say browsing the web) and the messaging application. In Windows RT though, you just snap the conversation window to the side and continue browsing, just with a narrower browser window. 

Messaging is just one usecase though - email, Facebook, Twitter, Skype video calls (their implementation is pretty cool - more on this later), music, a small browser window docked on the edge while writing in the main screen, the possibilities are endless. You could even theoretically turn it into three near-equal size windows using Aero Snap in Windows desktop, though that severely cuts down on usable space. But generally, the Snap feature gives the end user a lot of flexibility and makes multitasking a lot easier. 

Top and bottom edge swipes end up being more application specific. Swipe up from the bottom and you usually get some additional options, while swiping down from the top edge is usually more of a navigational tool (e.g. showing multiple tabs in IE10). 

Although Windows RT borrows from its iOS and Android brethren in that it will automatically pause and unload unused apps from memory, you can always manually move the process along by edge swiping down from the top and dragging the window off the bottom of the screen. This also works from the task switcher on the left side, drag over and down to the bottom of the screen to close. There’s some built in lag to ensure that you don’t accidentally quit something of importance but otherwise it works fine. 

Overall, the edge swipe gestures take some getting used to but once you’ve made it over the hump they really unlock a totally new level of tablet usage.

I believe Microsoft is on to something real here with the new Windows UI for tablets. This new OS feels ahead of the curve on major issues like multitasking, task switching and displaying multiple apps on the screen at the same time. I was always told that marketshare is lost and gained in periods of transition. Microsoft missed the first major transition to new ARM based smartphones and tablets, but it’s perfectly positioned to ride the wave to notebook/tablet convergence. In fact, when it comes to figuring out how to merge those two platforms I don’t believe Apple or Google have a reasonable solution at this point. In Apple’s world the two are distinctly separate, while Google is arguably even worse off as it doesn’t have a good notebook OS at this point (the verdict is still out on Chrome OS, as promising as the new Samsung Chromebook appears to be). It’s unclear how big this convertible/hybrid market will grow, but I see real potential here. There are users who want an iPad and I don’t believe Microsoft does anything to change their minds. The iPad and iOS remain a very polished, very accessible platform that is really optimized for content consumption and light productivity. For anyone who wanted more however, there’s now an alternative: Windows RT.

    That's a question that can be answered when more viruses are being written for ARM platforms. As it stands now, virus's we see on regular x86 machine really won't be able to execute on ARM platforms.

    All software for Windows RT must come from the Windows Store.

    This is EXACTLY like Apple and the iOS App Store. Therefore, unless Microsoft approves viruses and distributes them intentionally, it should be a non-issue.

    Even iOS has had a few leaks in the ship. Remember when you could jailbreak an iOS device by visiting a website in Safari? (

    I'm just wondering if some of the legacy of X86/AMD 64 Windows will make Windows 8 RT inherently less secure than an iOS device.

    But, as N4g4rok says above, I guess only time will tell.

    I'd still like to see an article that specifically addresses the strengths and weaknesses of Windows 8 RT. If that article exists, please point me to it. I've looked!

    Does anybody think it's realistic to get something like Chrome or Firefox into the windows app store? I like IE10 but (like Anand/Vivek) have always been a chrome guy. The ability to just "click" a tab to switch is really valuable for 10+ tabs open. Anybody share hopes for chrome or firefox to be developed for RT?

    Also: did you all notice any slowdowns when having like 10+ tabs open, or did you try it out ever?

    I know there is a Chrome install for the Modern UI in the regular windows 8. That works great since I can use adblock and certain script blockers. I did see Google search in the store so it may only be a matter of time before Chrome shows up there for RT devices as well.

    Does anyone here with a Surface RT tried using xfinity comcast online? I was just wondering if flash websites like xfinity or work on the RT tablets?

    Please let me know.
  • Spivonious - Thursday, October 25, 2012 - link

    MS has a built-in Flash that's enabled for certain white-listed sites. I imagine Comcast is in that list, but I don't have an RT tablet to try it out on.

    I don't understand ... what is the missing 6.7GB used for? There'd be a little bit of loss for file tables and such, but nowhere NEAR the 20% that indicates.
  • VivekGowri - Thursday, October 25, 2012 - link

    Factor in 7-8% for formatting loss, the rest I assumed was some sort of hidden recovery/restore partition with the factory image.

    What about swap file and hibernate file? I imagine they have a swap file.

    Probably no need for hibernate on these devices with the low power sleep states.
