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.

    The same search may not present you with the same results however due to changes in Windows 8 but essentially it should be the same.

    For those complaining this is what you need to make Windows 8 more like Windows 7, completely! Try, love it and move on.

    Really? Are you serious?

    You have no idea about the specialized software needs of other fields of study...
  • VivekGowri - Thursday, October 25, 2012 - link

    Sorry, sweeping generalization, but I can't think of a class I took in the first two or three years of undergrad that an RT system wouldn't have been adequate for. Only after you start getting into the upper division classes do you start having a lot of non-Office computing needs.

    the general public using facebook only are going to keep buying iPads, not windows tablets with physical keyboards.

    ARM's power consumption advantage is very marginal: the medfield based RAZR i has shown better standby than the almost identical RAZR M, as well as amazing talktime and slightly better video reproduction power consumption; where it fares worse is normal screen-on usage, but overall, it's hardly worse.

    So although there still aren't tests available of the newer dual core, I see no reason to expect worse standby power consumption (considering how intel manages to turn cores off completely); also cloverfield supports connected standby, which both ARM and RT do not, and it seems to be a pretty big deal to me.

    Clovertrail will run standard windows 8 (call it home premium if you will) which is as full as it gets unless you consider the pro features essential: it will still be able to run windows 8 pro anyway so it's up to OEMs to offer that version preloaded.

    As far as I know, the only difference between clovertrail tablets and standard PCs is that the software will be preloaded and the bootloader locked (there is no SATA support anyway); so with the exclusion of other OSs, you will be able to run all the x86 software you want.

    So, to the original question: why in the world would I prefer an ARM solution?

    And I don't believe we have to thank RT for Clovertrail: it was clear that Intel would have entered the mobile market, in competition with ARM, anyway.
  • SetiroN - Thursday, October 25, 2012 - link

    By "in competition with ARM" I mean It couldn't have done it at higher prices.
  • VivekGowri - Thursday, October 25, 2012 - link

    The only thing with Clovertrail is that it comes out to around $200-250 more if you want Office and a keyboard attachment. See $599 VivoTab RT/Surface RT versus the Samsung Series 5 Slate (or whatever they're calling it in the US - ATIV something or other.)

    It's an 11.6" Clovertrail tablet that goes for $749 with the dock. Looks great, too. But the thing is, you toss in Office 13 on top of that (because it's Windows 8, that's not included) and then the price ends up going from iPad range (RT) to ultrabook range (Clovertrail.)

    The clovertrail basically has the same price as the windows RT. the Acer W510 and Asus Vivo smart all cost 499. The surface RT is also 499 without the keyboard. But what i really don't understand is why those low end netbook level tablet are all much more expensive then the netbook, it make no sense to me. The article said the clovertrail and tegra 3 are actually half of the price of conventional ATOM which are used in all those cheaper netbooks. The netbook has more expensive processors (40 to 20), mother board (less integration), harddisk (320G harddisk is more expensive than the 32G SSD) and some other staffs (keyboard, big battery, touch pad). The only thing more expensive on the tablet is the display, but I don't think the display could cost 200 more then the display on the netbook.

    I've wondered about that as well. For a very marginal bit of extra weight and thickness and a bit less battery life, you can get a CT based tablet. That should have an enormous advantage in horsepower. I just wish there were some reviews of the CT devices. Hopefully soon. The only advantage I see with RT is the included Office.

    Ditto here about eagerly waiting for Clover Trail Windows 8 tablet reviews. At least anandtech drops some concrete "Clover Trail is faster than Tegra 3 tablets" benchmark results -- hopefully a full review is imminent.
