Explained: Wi-Fi Direct: what it is and why you should care

Explained: Wi-Fi Direct: what it is and why you should care

Wi-Fi Direct: everything you need to know

The world is falling out of love with cables, but the Wi-Fi we know and love isn’t always the best way to connect devices.

Wouldn’t it be great if you could effortlessly connect Wi-Fi devices without messing around with access points and lengthy passphrases? That’s what Wi-Fi Direct promises.

Wi-Fi Direct is a proper standard

It comes via the Wi-Fi Alliance, the global industry association in charge of certifying Wi-Fi kit.

Wi-Fi Direct is Wi-Fi without the internet bit

The idea behind Wi-Fi direct is that simple tasks need simple connections. For example, you might want to print from your laptop or smartphone to a wireless printer, or to share images with someone else in the same room, or to transmit video from your phone to your TV. None of these things requires an internet connection, but they do need to connect – to the printer, or to the other person’s hardware, or to the TV. With Wi-Fi Direct, that bit’s easy.

Wi-Fi Direct can have the internet bit too

If you have a Wi-Fi router connected to the internet, you can connect to that too.

Wi-Fi Direct doesn’t need a wireless access point

Wi-Fi Direct devices can connect to each other without having to go through an access point: they can establish ad-hoc networks as and when required, letting you see which devices are available and choose which one you want to connect to. If that sounds very like Bluetooth, that’s because it is.

Wi-Fi Direct uses Wi-Fi Protected Setup

You don’t want any Tom, Dick or Harriet to be able to connect to your stuff – for example, you might not want to see what the neighbours are beaming to their TV on your TV – so Wi-Fi Direct uses Wi-Fi Protected Setup [PDF] and WPA2 to prevent unauthorised connections and keep your communications private. There are two ways to establish a connection: with physical buttons – “press the button on gadget X and then the same one on gadget Y”, or with PIN codes.

Wi-Fi Direct knows what’s nearby

Wi-Fi Direct includes two potentially useful things: Wi-Fi Direct Device Discovery and Service Discovery. Your device doesn’t just know there are devices available; if developers have enabled it, your device will know what kind of devices are nearby and what’s on offer – so for example if you’re trying to display an image, you’ll only see devices that you can beam images to; if you want to print, you’ll only see devices that are or that are connected to printers. Crucially this can happen before you connect, so you don’t waste any time trying to connect so something that doesn’t do what you want it to do.

Wi-Fi Direct uses the same silicon

Manufacturers don’t need to add extra radios to their kit: the idea is to have Wi-Fi Direct as part of the standard Wi-Fi radio. It’s backwards compatible too, so you don’t need to throw out your old Wi-Fi-enabled kit.

Wi-Fi Direct is part of DLNA, and Android too

In November, the Digital Living Network Alliance (DLNA) announced that it was including Wi-Fi Direct in its interoperability guidelines, and Google has added Wi-Fi Direct support to Android 4.0 Ice Cream Sandwich (for example it’s in the Samsung Galaxy Nexus‘s networking options). DLNA says it “expects DLNA Certified and Wi-Fi Certified Wi-Fi Direct smartphones to grow strongly through 2016.” That could be an awful lot of smartphones.

Fujitsu takes on west with phones and tablets

Fujitsu takes on west with phones and tablets

Fujitsu is planning to take the European and US mobile market by storm this year with a slew of new Android and Windows Phone tablets and smartphones.

After years of playing in the Japanese phone market, Fujitsu is branching out and hoping to get in on the lucrative European and American smartphone action – just as Panasonic does the same thing.

But while we’re not expecting anything more than a smartphone from Panasonic, Fujitsu has a range of handsets plus tablets to offer, taking in both Android and Windows Phone.

Hardware details

Not much is known about the actual hardware at this point, although reports suggest all models will come equipped with NFC, LTE connectivity and biometric security (like fingerprint unlock).

At this year’s CES, Fujitsu showed off a Tegra 3 quad-core superphone prototype – here’s hoping that speaks of things to come.

Fujitsu has already been in talks with European operators about offering the devices, and claims what it has up its sleeve is “a global product”.

Robert Pryke, director for Fujitsu’s mobile phone business in Europe, said, “The Japanese market has been in a silo from a technology and design perspective, but Fujitsu is bringing out a global product.”

There’s a good chance we’ll see the new Fujitsu tablets and smartphones get a MWC 2012 unveiling: in which case, we’ll be there to bring you our hands on reviews just as soon as humanly possible.

Tutorial: How to install Android on other devices

Tutorial: How to install Android on other devices

Installing Android on other devices

It’s the open-sourced nature of Android that has enabled it to proliferate so widely, but it’s the touch-friendly interface that has had it so eagerly embraced by so many.

This has enabled anyone that wanted, to direct their intellectual powers to porting Android to any device they want.

This has lead to disgruntled owners of Android devices that have waited a few months too long for OS updates to create their own updated builds.

Owners of devices with outdated or dead operating systems – such as Windows Mobile – have devised builds of Android of their own.

While people who just fancy the damn challenge have done it for perfectly functioning devices, such as the iPhone 3G.

Robot spares

HP touchpad

For this example we’ve picked the HP TouchPad, there was a lot of noise about this in mid-2011. HP announced it was dumping its WebOS division and there was a fire sale on its only tablet the HP TouchPad.

This runs WebOS, which, while in itself is a fine OS, has very limited third-party app support. With the death knell sounded for WebOS the challenge was on to create a working build of Android.

The renowned hacker group, CyanogenMod took up the challenge and delivered a working alpha in a month.

So how do you go about replacing the OS on a device? It’s just like replacing an OS on a standard PC but with the added complications of gaining the right access to the original OS; having the tools to inject a replacement boot-loader; and having access to a replacement OS with the correct drivers in place. Sounds tricky, doesn’t it?

Thankfully the internet is a vast and varied place, inhabited by helpful and intelligent types. Sites like http://xda-developers.com and http://rootzwiki.com host communities of avid Android fans, dedicated to creating builds of Androids for specific devices. These gals and guys have created an armoury of tools that people can easily reuse for a host of devices.

Missing a pillar

HTC phones

Three basic pillars are required: a copy of the target OS for the device; a system to inject this onto the device; and a boot-loader to kick start the device with the new OS.

The injection stage is interesting as it usually hijacks the manufacturer’s built-in firmware upgrade or recovery process. Most devices provide a low-level recovery mode that involves holding down a combination of hard buttons as it’s turned on.

With the HP TouchPad this is the Volume Up button. For other devices, such as the iPhone this is initiated via the software itself.

Beyond that initial process, of course, a build of Android is required, ideally but not necessarily with all the device drivers in place. As with Windows, lacking a driver doesn’t necessarily break a device but renders that part – be it the GPS, Wi-Fi or audio for example – useless or in other cases semi-functioning or often functioning but lacking power-saving features. If you jump onboard a part-done build you’ll often find such issues.

Last, the boot-loader kicks the whole thing off. For some devices, usually those that cannot be flashed, this is a one-time process that has to be rerun each boot. The HP TouchPad gets the best of all worlds as it can be partitioned and have a multi-OS boot-loader installed called Moboot.

You won a brick

iPhone android

Do be aware there is a chance of bricking your device. We strongly advise backing up your data and any files on it. It’s well worth fully charging the device beforehand and leaving it plugged in as well.

Once the ‘upgrade’ is initiated don’t interrupt it, even if nothing seems to be happening. Once Android is in place there can be issues with Android Market and it will often need installing separately, but we cover that below.

On some devices it may also block many apps as the device isn’t correctly recognised. This can often be fixed by clearing and force stopping the Google Services Framework and then the Market via application settings.

Beyond this there’s a world of Android enjoyment to be had. The Android 4.0 source code has been released too, so we’re expecting a slow update for many devices to the tasty Ice Cream Sandwich.

Disclaimer: Future Publishing Limited provides the information for this project in good faith and makes no representations as to its completeness or accuracy. Individuals carrying out the instructions in this project do so at their own risk.

Installing Android: How to do it

Part 1: It’s easy, like brain surgery

1. All your fault

prep 1

Let’s be up front, this is third-party alpha software that replaces the boot-loader and installs Android. Things can go wrong and if they do it’s all your own fault. We strongly suggest you back up.

Select Launcher > Settings > Backup to secure at least your settings. We’ll outline later uninstall and emergency recovery options that could save a seemingly bricked device.

2. Get ready

prep 2

First, make sure your HP TouchPad has at least 2GB of space free. It’s usually not an issue.

Next, you’ll need your USB data cable to hand and download the required files from the RootzWiki page. Four files are essential: ACMEInstaller ZIP, CM7.1.0-tenderloin-a3-fullofbugs-signed ZIP, Clockwork Recovery ZIP and the Moboot ZIP.

Only extract the ACMEInstaller.

3. Get even more ready

prep 3

You will also need to download the HP TouchPad Novacom driver, this is usually part of the SDK but you can grab just the driver from here.

If you don’t have Java installed grab that as well from http://java.com and run the JAR file you just downloaded. This installs the driver required to access the HP TouchPad in its recovery mode to inject the new boot-loader.

Part 2: Wipe out WebOS

1. Fire the files

install 1

Boot the HP TouchPad into WebOS as normal. Attach it to your PC via the USB and mount it as a drive. Open My Computer, locate the HP TouchPad and in the root create a cminstall folder.

In to this copy the three unextracted ZIP files: moboot, update-cwm, and updatecm-7.1. These represent the Moboot, ClockWork Recovery and CyanogenMod Android files.

2. Moment of truth

install 2

Eject the HP TouchPad from the PC as normal and power it down. Turn it back on while holding the [Volume Up] button. As soon as it’s on a large white USB logo should appear.

Connect the HP TouchPad to the PC and it should be detected as new hardware via the Novacom driver. If the TouchPad isn’t recognised you need to get the Novacom driver installed. Try a reboot if you haven’t already.

3. Install Android

intsall 3

Extract the ACMEInstaller file to the desktop. Select Start, type ‘CMD’ and click ‘OK’. In the command prompt type ‘CD desktop’, press [Return] to change directory to the desktop.

To start the Android install, type the following line into the command prompt. If Novacom cannot be found, locate the Program Files > Palm > SDK folder and copy it to the desktop: novacom boot mem:// < ACMEInstaller

4. Android activate!

step 4

After a moment of nothing, a stream of Linux command lines should appear. This install process will go on for ten minutes or so, after which the HP TouchPad will reboot. Ignore the boot-loader and Android will start.

Play to your heart’s content but a big omission is the Android Market, but we can fix that and it’s an excellent introduction to the ClockworkMod Recovery Mode.

5. Moah apps!

install 5

Legally Android Market cannot be distributed with CyanogenMod Android. Download the package from http://gooinside.me/gapps. Connect the TouchPad to your PC as a drive and copy this ZIP file to the root.

Eject and reboot the TouchPad, at the new Moboot boot-loader use the Volume Button to select Boot ClockworkMod and press the Home button to start.

6. The Market is open

install 6

ClockworkMod enables you to do all manner of low-level recovery and update things. Use the [Volume Button] to navigate to ‘install zip’, the sdcard refers to the internal storage. Use the [Home] button to select.

Select ‘Choose zip from sdcard’, select the gapps ZIP file you saved to the root. Confirm the warning, select ‘Reboot system now’ and let it reboot into Android. Now you have full Market access.

Part 3: Disaster recovery

1. Recovery options

recover 1

The ClockworkMod Recovery provides a number of recovery and restore features that can help reset and fix problems. Access it from the Moboot boot-loader using the [Volume Button] and [Home] button to select.

Options that can fix locking and freeze issues include: Wipe Cache Partition, Advanced > Wipe Dalvik Cache and Wipe User Data. The last one will reset Android to factory defaults.

2. Refresh Android

recover 2

Within ClockworkMod Recovery you’re also able to reset CyanogenMod Android by effectively getting it to reinstall Android on top of itself.

Boot into WebOS, mount it as a drive and copy the CM7 fullofbugs ZIP file to the root. Eject and reboot the TouchPad and start ClockworkMod Recovery. Choose the ‘Install zip’ from sdcard option and select the Zip from the root.

3. Android begone

recover 3

If you decide Android’s not for you the good news is that an uninstaller is available. We can see this being automated in the future but even in the alpha stage it’s nothing you’ve not already done.

Download and extract the Uninstaller Zip file from the RootzWiki TouchPad website. Open a command prompt, change the directory to the Desktop and type: novacom boot mem:// < ACMEUninstaller.

4. It’s all gone wrong

recover 4

The above step takes a few minutes for anything to happen but will restore your device to its pre-Android state, recovering partition space.

There is one last recovery option with WebOS Doctor found here. You’ll need your HP WebOS account details, at least five per cent charge and Java installed. The entire reset process shouldn’t take more than half an hour.

In Depth: How touch will transform games on Windows

In Depth: How touch will transform games on Windows

Touch in Windows 8

Ubiquitous access to touch-enabled devices is going to mean every Windows game developer on planet earth will be looking to integrate touch features into their latest release.

So we can take a look at how touch-enabled systems will run Windows 8, enhance your gaming experience and generally make the world a better place.

There’s simply no arguing that Microsoft – publisher of the single most important OS on the planet – has been utterly routed by the more nimble Apple and Google.

It may have released touch-enabled systems years ago with Windows Mobile and Windows Tablet Edition, but in its usual blinkered this-is- to-sell-more-Windows way managed to kill the market dead for these and many other innovative products. Anyone remember Microsoft Smart Display? Or project Courier?

This time around touch will be different. Microsoft doesn’t have to innovate, phew, as Apple and Android has done all of that for it. We can just sit back, relax and wait for the touch-enabled, app-store-integrated, widget-brandishing, button-sliding progeny of Windows to make its appearance.

The odd thing is, it’s really rather exciting. For the first time we’re going to have the chance at a genuine ecosystem of Windows devices to choose from: moving from Windows phones, to Windows tablets up to netbooks and laptops and then desktop systems. All touch-enabled, all interconnected via Windows Live and all offering the same touch games and applications.

Next generation hardware is already appearing so let’s take a look at how touch-devices work with Windows 8, existing and future games.

MSI ae2200

The gloss-black MSI all-in-one flares into life. The remnants of an ancient BIOS briefly shows itself – still infecting even this most modern of machines – before a Metro-style pale-blue OS boot menu presents itself. Its uber-modern fine sans-serif type couldn’t be more removed from the chunky fixed-type on BIOS screens of old.

Tap the extra options and you see a selection of recovery and boot features, before going back and tapping the frame-less Windows 8 button to start it. Within seconds a widescreen HD mountain vista is displayed, the date and time boldly displayed in that stylish new Segoe typeface.

A swipe up reveals the Windows user accounts, ideally tied to Windows Live accounts they will take your preferences, avatar images, email, documents and apps with you to any device you use. Tapping one brings up the visual lock-screen – a personalised picture that requires you to motion over areas you’ve previously selected to gain full user access.

Security passed, the new Windows 8 Start Menu springs forth; this living breathing menu emanates life, as individual app cards update and refresh themselves. Feeds show real-time posts and games show online players stats.

The expansive, horizon-style Start Menu can be effortlessly scrolled through, with a tap here you can check your tweets, a tap there you can scroll through your latest news streams.

Media Center makes it a simple job to flick through menus of media and choose the music, photos and films you want to view. Tap the latest Windows Store, grab a game and enjoy gaming in a new way.

Hands on with Windows 8

Windows 8

The release of Windows 8 will simply solidify this touch journey but for now models, such as the MSI Wind Top AE2210 or the Dell Inspiron 2320 – both all-in-one models – elegantly show the touch-enabled future that awaits as they can have the Windows 8 Developer Preview installed on them.

We know the Developer Preview was really a beta version but even so, the semantics of a number of gestures were a little unnecessarily obscured. Using it you get a better idea that the demo at last year’s Microsoft Build conference while live had been well practised and orchestrated.

We regularly ran into issues trying to switch between apps and the dock system seemed limited and frustrating to use. But it’s hard to complain about something that hasn’t even been released in an official form. Even guessing, there’s no chance of a Windows 8 release until summer 2012. Microsoft has a lot to sort out before then beyond just getting a swanky touch-interface working correctly.

The Windows Store is probably the easiest, cross-device migration of settings and is another easy thing to sort via Windows Live accounts.

But it’s the often overlooked elements of life where pleasure can really be taken, like reading on the toilet or removing an annoying bogey from your nose. Our old-friend Windows Media Centre is an excellent touch-enabled bit of software.

Whether that’s through luck or flaw we can’t say, but flicking through films, music and photos is a lovely experience. One we’re sure could be made even better if a little style and thought was put into it.

The Media Center photo screensaver is still one of the worst experiences we’ve had besides hiding under our bed covers as children listening to our parents fight.

Windows playtime

Dell touch

Where our real interest lies is with gaming. Touch on mobile devices has ushered in a new way to game. While we’re not expecting the same paradigm shift on the desktop, access to casual mobile games will always be a good thing, but we do expect touch elements to start drip feeding into triple-A titles.

The splendid thing is we can already try some of these features out on existing titles, that have been either knowingly or unwittingly enabled for touch gaming. The richest area of gaming for touch-aware titles is the hated casual game, you can stop making hissing noises. Some people – we imagine a few of those that have racked up over half a billion downloads of Angry Birds – actually do like what we deridingly call ‘casual’ games.

Angry birds

With many Flash-based browser games designed for easy mouse input, or more likely for touch-aware input, these are all able to work flawlessly with a touch PC. We’ve already mentioned the most obvious casual game: Angry Birds. This has a free PC version online at chrome.angrybirds.com that works on any HTML5-aware browser and plays beautifully on touch-screen equipped PCs and on a much larger scale than any tablet or phone could hope to manage on its own.

We did run into a few odd instances with Internet Explorer, it has its own touch-controls built in and a wrongly-placed finger can have you browsing off to other locations. Equally well-equipped are the flash-based games to be found over at www.popcap.com the likes of Bejeweled and Plants Vs Zombies, these Flash games again work perfectly on a touch-enabled PC.

It’s also worth pointing out the browser add-in Swiffout.com that enables you to run embedded Flash games full screen. It’s a bit hit and miss, as in it’ll sometimes seem like the game isn’t doing anything.

If you think there’s a big selection of casual games available online now, just you wait until Windows 8 hits the streets. We’d expect most Windows Phones games to be quickly ported, that’s if they’re not natively supported from day one, while dedicated Windows 8 Tablet games are going to quickly appear.

If casual gaming is your thing, if nothing else children gobble them up like space-dusted cake, then expect a flood to come in from Android and iOS devices.

Touch in mainstream games

DEUS ex human revolution

Fortunately, touch is coming to mainstream gaming too. Well, it’s actually already here but it’s either surreptitious or else it’s accidental, but we’re still claiming it’s real.

The formats that are going to gain the most outside of the casual arena are adventures and strategy games. You may have spotted that both of these have the advantage that they’re not necessarily the fastest paced of games.

The big issue, particularly for RTS games but can even affect adventures too, is that a quick-tap is equivalent to a left-click and a long-tap performs a right-click. This effectively eliminates the ability to do quick right-click actions.

Most dedicated touch devices have developed alternatives, such as the two-finger tap or hold one finger down and tap second. Unless a game is developed with touch in mind, you’re stuck with what Windows 7 has to offer, and that’s limited.

Even with these limitations many adventure games and less hectic strategy games play wonderfully on a touchscreen. If anything we love the switch you can make between active moments using the mouse and more contemplative sections using the touchscreen interface.

The same type of system goes for some RPGs as well, though many tend to lean heavily on mouse and keyboard. Non-combat areas such as inventory management, spell casting or crafting can all take advantage of touchscreen input.

One genre of gaming that we’re not expecting touch to have an impact on is first person shooters. This a PC genre that is very much going to stay a realm of the mouse and keyboard. That’s not to say touch systems aren’t able to run them, and in a similar way to RPGs we can see room within FPS titles to add extra interactivity into the game world by using touch within environment.

Take Deus Ex: Human Revolution, which has a world littered with supposedly interactive elements from touch newspapers to hackable door locks. To make these mouse accessible the game almost has to cut away from the world so you can click on the right parts with the mouse, with a touchscreen they’d be no need and you could directly interact with the game world.

The same goes for any games with in-world elements, while touch could be used for physical game-world interaction. So picking up and manipulating items via touch to complete physics puzzles or just completing a weapon loadout.

None of this in itself is going to change the world, but it’s certainly going to change how you play in your gaming worlds.

Touchy me, touchy you

Touch pc

Like us, many of you will be thinking ‘I’m never going to lean forward and touch my screen’. You’re probably right, it’s a lot of effort and not entirely natural thing to do, especially when sitting down.

We’re sure touchscreens will appear but direct touch could well be limited to tablets and all-in-one systems. However, Kinect and the Acer Aspire Z5xxx range, with their front-facing cameras, show a way of interacting that cuts out that bacteria filled touching business with seemingly reasonable precision.

We used the Windows 8 Developer Preview and those two up-to-date all-in-one touch panel PCs mentioned previously: the MSI Wind Top AE2210 is a lovely Intel Core i3 2100 Sandy Bridge graphics, 20-inch unit, which sells for a little over £650.

The Dell Inspiron 2310 is more up-market with an improved Intel Core i5 and Nvidia GT 525M graphics chipset. This has a little more muscle but is also a little more pricey, selling at around £799.

Interestingly both use what we suspect is the same two-point touch sensor. We suspect this is an IR-based system as they both detect finger movement before contact is made and there was vague issues with accuracy at the extreme edges of the screen.

That aside both worked flawlessly with the Windows 8 Developer Preview OS indeed they were both as fast as when used under Windows 7. Tablets and phones are going to continue to be the main focus for touch, but we’re waiting to see what trickles down to the PC.

Opinion: Windows 8 on ARM? Intel must be laughing

Opinion: Windows 8 on ARM? Intel must be laughing

Our columnist Gary Marshall points out that Microsoft’s decision to prevent third-party apps on ARM-based Windows 8 desktops will only serve to confuse.

He’s right. And, what’s more, it horribly hobbles ARM-based Windows 8 hardware to the extent that Intel will be rubbing its hands together with glee.

Last September I suggested that ARM-based Windows 8′s lack of legacy app support was the elephant in the room for the OS. It still is.

People won’t understand they can’t just download and install legacy apps on something that looks like a standard Windows 8 desktop. That’s not what Windows means to people.

OK, so there will be Office 15 apps and other bits and pieces pre-installed, while we will have plenty of lovely third-party apps using the Metro interface. But the ARM Windows 8 desktop won’t be a flexible experience.

And that can only mean customers will turn away – indeed, I feel that this news means that manufacturers will play it safe and we’ll only see a few ARM-based Windows 8 tablets at the launch of Windows 8, rather than the plethora of multipurpose devices I’d hoped for.

You see, people will expect Windows 8 devices to give them options. New possibilities. They won’t want an iPad 3 alternative that has a bit of old Windows tacked on.

It’s up to Intel

We knew that x86-based devices would still dominate the Windows 8 landscape. But we had hoped that ARM-based Windows devices would take the OS beyond the traditional PC and give us some really exciting tablet-laptop hybrids that could be used for work or play. The single device to suit every occasion.

I was looking forward to having an ARM-based Windows 8 convertible running a chip like the Qualcomm Snapdragon S4, where I could use Metro in tablet mode but also get the full laptop experience with a keyboard and the Windows desktop when needed.

Now it seems that many of these more complex and interesting devices will end up being Intel-based, rather like the Lenovo IdeaPad Yoga we loved so much at CES 2012.

Lenovo ideapad yoga

IDEAPAD YOGA: We’ll be seeing a lot more Intel-based convertible Windows 8 devices

And that’ll be because manufacturers know what will sell. To be frank, people are so used to looking for something with Intel inside.

Intel made it clear at CES that touch-based Ultrabooks will be with us for Windows 8, and many of these could be convertible devices using the Core series of processors.

Intel is keen to make inroads into the tablet market and recently announced the Atom chip it hopes can compete with ARM in many phones and tablets.

Despite the Atom’s relative lack of power and battery life compared to the best ARM silicon, it will be rather happy at the possibilities that Windows 8 can bring.
