Ubuntu Tablets: Less Jarring Than Windows 8?

Posted by Soulskill on from the fewer-solid-color-rectangles dept.

Following up on yesterday's news that Ubuntu for Tablets has been announced, Mark Shuttleworth answered questions about the purpose of the new version of Canonical's OS and what its intended strengths will be. He made special note of how Canonical wants the transition between desktop-Ubuntu and mobile-Ubuntu to be smooth. "When you transition from the tablet to the desktop, things don't move around. Your indicators, things like network status and time, they don't jump around on screen, they stay in the same place. That's what's really different certainly between our approach to convergence and for example Windows 8, where when you're in the desktop mode, which looks like Windows 7, and suddenly you get the new tile-based interface, it's a stark transition that can be jarring for users. In our case, you can almost think of those as gentle phase changes. When you go from phone to tablet you're stretching the device in very obvious ways. People who've used iOS on both phones and tablets would expect that. What's nice about Ubuntu is the phase change to the PC experience up from the tablet really just introduces window management, and it also introduces things like menus and dialog boxes. You aren't moving things around in dramatic ways." He added that they expect the user experiences to converge in Ubuntu 14.04. Shuttleworth also addressed the fragmentation problem faced by Android. He says manufacturers and carriers don't want to fall into that trap again, and that they've been receptive to the idea of leaving the core of Ubuntu alone while tweaking their individual services instead.

  1. Keep the code, separate the UIs by thelamecamel · · Score: 5, Interesting

    Now I finally see what Shuttleworth's been meaning when he says the same applications run on all form factors - as a developer, you separate the logic from the UI, and write three UIs: one for phone, one for tablet, and one for desktop. Until now I thought "nice in concept, but what's the point?". But if your device itself suddenly switches from a phone or tablet to a desktop, then your app can keep running and switch UIs on the fly.

    What I really find neat is how tablet apps can become phone apps when docked on the side, for multitasking. This finally looks like a tablet that's not purely for consuming content.

      Separating UI from logic is a design paradigm that is well over 10 years old. It's generally a good idea, not just for different form factors like this, but for cross platform apps where you may not have a good UI library across all target platforms.

      Yeah, but in practice has anyone ever been able to get it to work across radically different platforms? I mean, you're talking about moving on the fly from the ARM architecture with low memory, weak video drivers, etc. of a tablet to a full-on desktop system--just by changing the UI? Sounds like a great idea, but implementing it would be a fucking nightmare. It's hard enough as it is just trying to support all the possible desktop configurations.

      The thing is, I'm not convinced you actually want to have a separate UI... The Microsoft strategy of shoving a phone/tablet UI on a desktop or a desktop UI on a phone/tablet is clearly moronic, but I think there is some middle-ground where you can design a UI that works well for all the hardware.

      For one thing, there doesn't seem to be a clear distinction between phone/tablet/laptop/desktop - if we look at the hardware, all of these devices have varying screen sizes and they can all have varying combinations of input technologies - my phone has a keyboard, some laptops have touch screens, you can connect a keyboard and mouse to a tablet. What we have is more like a continuum:
        - phones tend to have small touch screens with no keyboard (but some phones are practically big enough to be verging on "small tablet" size, some phones have keyboards and trackballs, pretty much any android phone can have a bluetooth/usb mouse and keyboard attached to it). Many phones can also be plugged into external monitors.
        - tablets tend to be a bit bigger than phones (but there isn't a lot of difference between a small tablet and a large phone). They have touch screens, but again, you can connect keyboards and mice to them, plug them into external screens, etc.
        - laptops are often, again, a bit bigger than tablets. But again, there's a cross over here - a small laptop may have the same screen size as a large tablet. They have keyboards and trackpads and you can connect external keyboards, mice, screens to them. But many laptops also have touch screens - what's the difference between a touch screen laptop and a tablet with a keyboard and mouse?
        - desktops are usually treated the same as laptops. Again, often bigger screens (but not always), they have keyboards and mice but nothing stopping you having a touch screen.

      So where do you draw the line - at what point do you say "we're now on a tablet" and switch to the tablet interface? What's the justification for switching the *entire* UI to a tablet interface? Is it down to the input devices available? If I unplug the keyboard and mouse then am I suddenly incapable of using multple windows at once? Similarly, if I connect a keyboard and mouse to a tablet, do I suddenly expect to lose all the touch screen controls?

      As for screen sizes - certainly as the screen gets smaller I'm more likely to want applications full-screen; and conversely for large screens I'm more likely to want applications in windows. But this isn't necessarilly the case for all applications. For example, even on a tablet, I may want an instant messaging conversation to be displayed at the same time as surfing the web, so enforcing full-screen-everything seems like the wrong approach.

    Unity is not that bad, let's not exaggarate. Newer versions are getting speedier and more customizable so I expect most of the Ubuntu-using Linuxers will accept it.

    That said, I also installed Linux Mint on my primary machine but I have Ubuntu/Unity on others. Unity works fairly well on my ARM Chromebook even without hw accelerated X.

    Speedier? Male cow excrement! On my hexacore desktop with SSD, Unity Dash takes a good half second to open. Similar features that are instant on Windows 8, OS X, Gnome 3 or KDE. If by any chance I have a maximized window open, it can take a good 2 seconds. I like the idea of Unity, I like the concept of Unity, but it's a slow piece of shit.

    Disclaimer: I use Ubuntu both at home and work.

    When I sit down at my PC, I want an interface that is designed for use on a PC, using a mouse and keyboard, and a large display.

    When I pick up my phone or tablet, I want an interface that is designed for use on a phone or tablet, using finger swipes, taps, and gestures, and a small display.

    THESE ARE TWO COMPLETELY FUCKING DIFFERENT THINGS.

    Stop trying to make them the same.

    Read page two, doofus:

    "Developers will be able to ship a single application binary which itself can respond to the different form factors," Shuttleworth said. "You will be able to write a single application binary that can run on a phone, or a tablet, a PC, or a TV, and it will declare to the system which of those form factors it can support and we will present the appropriate interface for that application on each of those form factors."

    Thankfully the snooping is going to remain optional (although still opt-out rather than opt-in). I've still got it turned off on my desktop, but reading documents like this (specifically the Data and metrics passed to the Smart Scopes service section) are a little reassuring, in that you can see that the developers are thinking about how to take only the data they need and are trying to protect it. I particularly like their (far-off) plans for sending location information: they won't send your exact co-ordinates like Google or Apple does - they'll round them off to maybe a 10km square because that level of location accuracy is probably not needed for the search. There's also a friendlier summary of the spec available.

    That said, while this kind of fuck up is still happening, I'm going to keep online search off, despite being tempted by functionality like its iView (Aussie Hulu) support.

    I too hope that you don't need an Ubuntu One account to use the tablet...

    If they can't get good linux drivers for their graphics card, then it's very possible they're stuck with no 3D acceleration. Depends whether the rig was intentionally built for linux or not.

    You weren't paying attention. He isn't pushing Linux, he's pushing Ubuntu. The entirety of the system here is what he is selling.

    The point of the transition is that the tablet physically becomes the desktop when you simply add a keyboard and mouse, probably via Bluetooth. You don't drop your tablet when getting home or to the office, you just dock it. There is just one device. Well, two as you'll also have a phone.

    What this seems to hope to achieve is a seamless computing experience with no "put this down, boot the PC, do work, shut PC down, grab tablet and go".

    Sort of a "one device to rule them all". After watching the video, I was far more intrigued than I expected to be. I fully expect my reaction to be "what a stupid fucking idea", but instead found myself saying "damn, that actually looks nice. I want one."

    And this shows how much Mr. Shuttleworth doesn't get the phone and tablets manufacturers and carriers and why there is no hardware partner and in my opinion they will not have one soon, like Ubuntu TV still doesn't have one. The reason Android took off is because Google was very careful to rebuild a lot of common Linux distribution modules by Apache licensed ones, for example the libc library. Manufactures and carriers want full control, they tolerate the GPL in the Linux kernel because they have no other viable option, but they don't like it (I am talking about them, I am not saying that I hate the GPL before people start implying that). Do you think Samsung will be happy to be forced to share their Android modifications that allow multiple applications (some vetted ones) on the same screen with all other OEMs?

    These words of Mr. Shuttleworth only gives me hints that they have no secret hardware partner
