0:00:02 > 0:00:05Cheese, cheese, cheese, cheese, cheese, cheese, cheese,
0:00:05 > 0:00:08cheese, cheese, cheese, Jews, cheese, cheese, cheese, cheese,
0:00:08 > 0:00:09cheese, cheese, Manchego!
0:00:24 > 0:00:27Welcome to Click. I'm Spencer Kelly.
0:00:27 > 0:00:30It is a beautiful, crisp spring morning.
0:00:30 > 0:00:33And, currently, thousands of people are streaming into the most
0:00:33 > 0:00:36important event on the calendar...
0:00:36 > 0:00:40if you like mobiles, because this is the Mobile World Congress,
0:00:40 > 0:00:43and it takes place here in Barcelona.
0:00:44 > 0:00:48It's a show to make you smile as we go mobile mad.
0:00:48 > 0:00:52As well as the big launches, we'll bring you the phone that
0:00:52 > 0:00:56sees in 3D, and the phone that can't be seen at all.
0:00:57 > 0:01:00We'll go underwater, and over the top.
0:01:00 > 0:01:01And, if that's not enough,
0:01:01 > 0:01:04there's the best of the web in Webscape, too.
0:01:09 > 0:01:11The Mobile World Congress grows every year.
0:01:11 > 0:01:15More than 70,000 visitors explore eight halls
0:01:15 > 0:01:19and nearly 100,000 square metres of exhibition space.
0:01:19 > 0:01:22Everyone has something mobile to show off.
0:01:22 > 0:01:24Phones, tablets, and, increasingly,
0:01:24 > 0:01:28the newest form of mobile tech, wearables.
0:01:29 > 0:01:32The oldest mobiles are here, too, though. Cars. Of course, these days,
0:01:32 > 0:01:35cars are learning to understand their environment, like this
0:01:35 > 0:01:39example from Ford, which is using lasers to scan
0:01:39 > 0:01:43nearly three million points every second and build up a 3D model
0:01:43 > 0:01:45of the road ahead.
0:01:48 > 0:01:51Just across the road from the Fira Gran Via convention centre,
0:01:51 > 0:01:56possibly the coolest piece of 3D modelling tech I've ever seen.
0:02:00 > 0:02:04This is one of only 200 prototype devices in the world that
0:02:04 > 0:02:07make use of Google's Project Tango.
0:02:07 > 0:02:11It's an Android phone with added 3D sensors.
0:02:11 > 0:02:15In a similar way to Xbox's Kinect it, the phone sends pulses
0:02:15 > 0:02:17of infrared light into the room,
0:02:17 > 0:02:19and then records how it's reflected back.
0:02:19 > 0:02:23The result is a depth map of the space that you're in.
0:02:23 > 0:02:26As you move about the room, the phone's position
0:02:26 > 0:02:29and orientation are constantly recorded,
0:02:29 > 0:02:32using a combination of the phone's gyroscope
0:02:32 > 0:02:34and complex image tracking,
0:02:34 > 0:02:37which works out how the image is moving about.
0:02:37 > 0:02:41Crucially, for navigating indoors, it doesn't need GPS,
0:02:41 > 0:02:44or any other wireless signal to work out where it is.
0:02:44 > 0:02:48The theories behind 3D mapping a room,
0:02:48 > 0:02:51a landscape, or an environment in this way aren't new.
0:02:51 > 0:02:54But they are incredibly processor intensive.
0:02:54 > 0:02:58And what is new is being able to do all that thinking
0:02:58 > 0:03:02in real-time inside a mobile phone.
0:03:02 > 0:03:04Now, that IS cool.
0:03:06 > 0:03:09Mobile technology that can understand its environment
0:03:09 > 0:03:11is one of the holy grails of computing.
0:03:11 > 0:03:15It opens the way for applications, such as modelling buildings,
0:03:15 > 0:03:17or navigation for robots which can get about the place
0:03:17 > 0:03:19without bumping into things.
0:03:21 > 0:03:24Handy for Google, a company which already has a fleet
0:03:24 > 0:03:27of self driving cars and at least
0:03:27 > 0:03:29seven robotics companies under its wing.
0:03:32 > 0:03:36Now, many of the big technology success stories have been
0:03:36 > 0:03:40built on gathering huge amounts of data about their surroundings,
0:03:40 > 0:03:42and, also, about us.
0:03:42 > 0:03:46With so much data being transmitted by our phones, one company,
0:03:46 > 0:03:49at least, is focusing on protecting our security.
0:03:49 > 0:03:53We've talked about the Blackphone on Click before,
0:03:53 > 0:03:55but this is where it launched.
0:03:55 > 0:03:58And Jen Copestake went to have a look.
0:04:01 > 0:04:04The revelations by whistleblower Edward Snowden
0:04:04 > 0:04:08into the mass trawling of meta data have led many to question how
0:04:08 > 0:04:10secure their communications are.
0:04:10 > 0:04:12So, if you need to whisper in someone's ear
0:04:12 > 0:04:16from 1,000 miles away, we can help you with that.
0:04:17 > 0:04:21Making the timing of the launch of a security focused device ideal.
0:04:21 > 0:04:23And this is the Blackphone.
0:04:23 > 0:04:26From the outside, it looks just like any other smartphone.
0:04:26 > 0:04:29It's got a high-resolution display, a front and back camera.
0:04:29 > 0:04:33But what really sets it apart is what's running on the inside.
0:04:33 > 0:04:37It claims to offer encrypted text messaging and calls,
0:04:37 > 0:04:41but only where both sender and receiver are using the device
0:04:41 > 0:04:43or the Silent Phone app.
0:04:43 > 0:04:46It also allows you to control what information the phone transmits
0:04:46 > 0:04:48wirelessly as you walk around.
0:04:48 > 0:04:52A growing issue for privacy campaigners.
0:04:52 > 0:04:57What we can address successfully is the dragnet of information
0:04:57 > 0:05:00that we're seeing from the Snowden documents,
0:05:00 > 0:05:02the large-scale collection of traffic.
0:05:02 > 0:05:04It might collect the traffic,
0:05:04 > 0:05:06but they're not going to see the content.
0:05:08 > 0:05:11The phone will cost 629 US dollars.
0:05:11 > 0:05:14This includes a two-year subscription to the Silent Phone service,
0:05:14 > 0:05:17and a few invitations for others to use the software
0:05:17 > 0:05:19so you can have someone to talk to.
0:05:19 > 0:05:22It will be available on any GSM network.
0:05:22 > 0:05:25Silent Circle is run by a mix of cryptographers,
0:05:25 > 0:05:28and ex-Navy Seals, and Special Forces.
0:05:28 > 0:05:32So, perhaps no surprise who some of the first customers are.
0:05:32 > 0:05:36US Special Forces are using our products.
0:05:36 > 0:05:39As are the British Special Forces.
0:05:39 > 0:05:44My strategy from the beginning of the company has been to get
0:05:44 > 0:05:46government customers to create a kind of dependence
0:05:46 > 0:05:48on our technology.
0:05:48 > 0:05:52And, that way, it would reduce the chances that we would be...
0:05:52 > 0:05:56The government would try to pressure us into putting backdoors in,
0:05:56 > 0:05:59because it would create too much collateral damage to their own people.
0:05:59 > 0:06:03And, while this might be the most secure phone coming to market,
0:06:03 > 0:06:09Blackphone is keen to emphasise it is not completely NSA proof.
0:06:09 > 0:06:10Oh, heavens, no!
0:06:10 > 0:06:13If they really wanted to attack just YOUR phone,
0:06:13 > 0:06:15and they made it a priority, they would find a way in.
0:06:15 > 0:06:19A low-key launch, then, for a quiet phone.
0:06:19 > 0:06:23But not all the announcements were quite that subtle.
0:06:23 > 0:06:25STRING QUARTET PLAYS
0:06:25 > 0:06:29Probably the most anticipated was Samsung's behemoth
0:06:29 > 0:06:31of a hullabaloo, complete with orchestra,
0:06:31 > 0:06:36wannabe superstar execs, and, of course, new kit.
0:06:36 > 0:06:39First up was the new Galaxy S5 phone.
0:06:39 > 0:06:43Slightly larger than the S4 with better battery life,
0:06:43 > 0:06:46a 16 megapixel camera, and a fingerprint scanner,
0:06:46 > 0:06:51the S5 is also dust and water resistant, although not waterproof.
0:06:51 > 0:06:53As seems to be the fashion these days,
0:06:53 > 0:06:56the user interface now looks a bit cleaner and simpler, too.
0:06:56 > 0:07:00There's a big emphasis on health and fitness apps at the moment.
0:07:00 > 0:07:02The S5 comes with a whole raft of them.
0:07:02 > 0:07:05There's a pedometer, for example, to measure how far you've walked.
0:07:05 > 0:07:09There's a heart rate monitor which means if you hold your finger
0:07:09 > 0:07:12over this little red light at the back, it'll take your pulse for you.
0:07:14 > 0:07:17Possibly the most interesting feature
0:07:17 > 0:07:19was the ultra power saving mode
0:07:19 > 0:07:22which shuts down all non-essential parts of the phone,
0:07:22 > 0:07:24and turns the display black and white.
0:07:24 > 0:07:27Apparently, with just 10% of battery left,
0:07:27 > 0:07:31this will keep your phone alive for another 24 hours.
0:07:31 > 0:07:35Ironically, many of us at the press conference just now could have done with one of these.
0:07:35 > 0:07:37It is, after all, nearly 10pm,
0:07:37 > 0:07:39and most of our phones are on their last legs.
0:07:43 > 0:07:48This kit also made a bit of a splash. The Galaxy Gear Fit.
0:07:48 > 0:07:52It's a fitness wristband with a curved colour touchscreen
0:07:52 > 0:07:56and it's possibly this type of thing that will make wearable tech
0:07:56 > 0:07:58just that bit more fashionable.
0:07:59 > 0:08:03Now, the Samsung event isn't the only one happening here at the Mobile World Congress.
0:08:03 > 0:08:06Here's a round-up of the other big announcements from the show.
0:08:08 > 0:08:11Facebook founder Mark Zuckerburg used his keynote speech to extol
0:08:11 > 0:08:15his vision of connecting the entirety of the world via the Internet.
0:08:15 > 0:08:20And, after Facebook's acquisition of WhatsApp for 19 billion,
0:08:20 > 0:08:21they're on the right track.
0:08:21 > 0:08:24Already boasting 450 million users,
0:08:24 > 0:08:28WhatsApp CEO Jan Koum also announced a free voice calling feature
0:08:28 > 0:08:30to debut in the app later this year.
0:08:30 > 0:08:34Facebook has quietly pulled the plug on its own e-mail service.
0:08:34 > 0:08:36A spokesperson for the social network admitted
0:08:36 > 0:08:38they're making the change
0:08:38 > 0:08:41because most people haven't been using their Facebook e-mail address.
0:08:41 > 0:08:42Ouch.
0:08:42 > 0:08:45And it's not all about Keynote.
0:08:45 > 0:08:49Offstage, start-up Seene debuted its iPhone app which creates
0:08:49 > 0:08:53simple, interactive 3D models using only the phone's built-in camera.
0:08:53 > 0:08:56Sony unveiled its latest batch of waterproof devices.
0:08:56 > 0:09:00The Xperia Z2 smartphone and its tablet cousin the...
0:09:00 > 0:09:03Z2. Inspired.
0:09:03 > 0:09:06Chinese manufacturer Huawei weighed in on the battle for our wrists
0:09:06 > 0:09:09with its Talkband B1.
0:09:09 > 0:09:12The hybrid device doubles up as a hands-free earpiece
0:09:12 > 0:09:14and also tracks your fitness.
0:09:14 > 0:09:16Huawei is already a big player in China
0:09:16 > 0:09:19but has its sights set on the bigger things overseas.
0:09:20 > 0:09:24Away from MWC, one of the world's largest Bitcoin trading sites,
0:09:24 > 0:09:27MtGox, has disappeared off-line after the suspected
0:09:27 > 0:09:30theft of millions of pounds of the digital currency.
0:09:30 > 0:09:33It's rumoured up to 750,000 coins worth
0:09:33 > 0:09:37a staggering £200 million have been stolen,
0:09:37 > 0:09:40and the theft potentially gone unnoticed for several years.
0:09:40 > 0:09:44Six other Bitcoin exchanges have since issued a joint
0:09:44 > 0:09:48statement saying this didn't affect the resilience or value of Bitcoin.
0:09:48 > 0:09:50And back at MWC, Mozilla,
0:09:50 > 0:09:54the company behind the Firefox operating system, has showed off
0:09:54 > 0:09:58a prototype super cheap smartphone which could sell for just £15.
0:09:58 > 0:10:02Designed for the developing world, the phone uses the Firefox OS,
0:10:02 > 0:10:05has a touchscreen, a 1GHz processor,
0:10:05 > 0:10:07and a two megapixel camera.
0:10:07 > 0:10:09Not blistering specs, admittedly,
0:10:09 > 0:10:11but what do you expect for the price?
0:10:11 > 0:10:13It's expected to launch later this year.
0:10:17 > 0:10:20And Firefox isn't the only smartphone outfit
0:10:20 > 0:10:22that's targeting the developing world.
0:10:22 > 0:10:24Here's LJ Rich with news from Nokia.
0:10:26 > 0:10:27Thanks, Spen.
0:10:27 > 0:10:31Yes, it's the company that used to dominate the handset industry.
0:10:31 > 0:10:34And now Nokia's aiming to claw back some market share with
0:10:34 > 0:10:37a range of affordable smartphones.
0:10:37 > 0:10:39The Nokia X and Nokia X+.
0:10:39 > 0:10:41There they are, ladies and gentlemen.
0:10:41 > 0:10:45While Nokia's always been open to Windows,
0:10:45 > 0:10:48it's raised a few eyebrows by partnering with Google's Android
0:10:48 > 0:10:52for its new low-priced Nokia X smartphone range.
0:10:52 > 0:10:56When you look at the functionality of these phones,
0:10:56 > 0:11:00it's surprising to think these come in at under 100 euros for this one
0:11:00 > 0:11:02and 109 euros for this.
0:11:02 > 0:11:05This is the Nokia XL.
0:11:05 > 0:11:08Making a low-power, low-cost phone like this is a great way to
0:11:08 > 0:11:11mop up all that revenue from the developing world,
0:11:11 > 0:11:13especially for people who are skipping desktops,
0:11:13 > 0:11:16skipping laptops, and going straight to mobile.
0:11:16 > 0:11:19And it may look like a Windows interface but, actually,
0:11:19 > 0:11:24it's running a highly tweaked Android mashup called Nokia X.
0:11:24 > 0:11:28Instead of Google's services, like Gmail and Drive on Android phones,
0:11:28 > 0:11:30there's Microsoft's Outlook and One Drive.
0:11:30 > 0:11:33It's no wonder some people are calling the Nokia X
0:11:33 > 0:11:35a crossover phone.
0:11:35 > 0:11:38Of course, the manufacturer hopes the people will get on
0:11:38 > 0:11:41to its ecosystem and spend money on apps.
0:11:41 > 0:11:45With an estimated 1.8 billion people in the next five years getting
0:11:45 > 0:11:47connected for the first time,
0:11:47 > 0:11:51Nokia wants a slice of that purchasing power pie.
0:11:51 > 0:11:54The Mobile World Congress is full of exhibitors big and small.
0:11:54 > 0:11:57And it's amazing the sorts of things you do find
0:11:57 > 0:11:59when you immerse yourself in the halls.
0:11:59 > 0:12:03For example, here's a lab, which is itself quite immersive.
0:12:03 > 0:12:07Hands up whose phone has met its end after an accident like this.
0:12:07 > 0:12:10Well, this is why it happens.
0:12:10 > 0:12:12When water gets onto an electrical circuit,
0:12:12 > 0:12:16it causes the thing to corrode as soon as the current starts to flow.
0:12:16 > 0:12:22Within seconds, the circuits are ruined. But, here is one solution.
0:12:24 > 0:12:28Here are two tissues. They both feel exactly the same.
0:12:28 > 0:12:30If I dunk this one in this bowl of water -
0:12:30 > 0:12:33surprise, surprise - mache.
0:12:33 > 0:12:38But if I take THIS tissue and dunk it in the water, watch what happens.
0:12:41 > 0:12:44That is just the most bizarre feeling.
0:12:44 > 0:12:47It kind of fights the water. It doesn't want to go under it at all.
0:12:47 > 0:12:51And, even when it does, the water just sits on top of it.
0:12:51 > 0:12:54And when I take it out of the water...
0:12:54 > 0:12:56it's dry.
0:12:56 > 0:12:59The water's just completely run off of it.
0:13:00 > 0:13:03That is, to all intents and purposes, waterproof.
0:13:04 > 0:13:09The dry tissue has been nano-coated with an extremely thin layer
0:13:09 > 0:13:11of so-called hydrophobic material,
0:13:11 > 0:13:17which keeps the water just nanometres away from doing any damage - presumably by scaring it.
0:13:17 > 0:13:19Nano-coat your electronics in the same way,
0:13:19 > 0:13:23and no amount of electricity will cause a fuss - or a fizz.
0:13:26 > 0:13:29After five minutes, the untreated phone on the left
0:13:29 > 0:13:32is so badly corroded you can actually see it.
0:13:32 > 0:13:35The one on the right is totally protected.
0:13:36 > 0:13:41And now, from one kind of dunking to a completely different kind,
0:13:41 > 0:13:42with LJ.
0:13:52 > 0:13:56The French basketball team have won their last 18 games,
0:13:56 > 0:13:59but now I've come to give them a few tips.
0:14:04 > 0:14:07They're actually here at Mobile World Congress
0:14:07 > 0:14:09to demonstrate some technology.
0:14:09 > 0:14:11And of course, it's wearable.
0:14:13 > 0:14:15There are washable wires woven throughout this vest.
0:14:15 > 0:14:19The wires send data from the players' bodies, like their heart rate,
0:14:19 > 0:14:21to a detachable module on the back.
0:14:22 > 0:14:25It's a prototype, so the finished module will be half the size.
0:14:25 > 0:14:26A bit like me.
0:14:26 > 0:14:30Data can be sent via Bluetooth for each player to use personally,
0:14:30 > 0:14:35or all the players can share the data for more sophisticated analytics.
0:14:35 > 0:14:37Good performance analysis
0:14:37 > 0:14:40could make the difference between being on the winning or losing team.
0:14:46 > 0:14:50Actually, sport strategy and technology have been entwined for many years.
0:14:50 > 0:14:54Tennis changed radically after metal rackets were developed,
0:14:54 > 0:14:57and anyone playing with a wooden racket would simply not be able
0:14:57 > 0:14:59to keep up with the new technology.
0:14:59 > 0:15:02These days, the racket race is still on,
0:15:02 > 0:15:05with modern ones made from aluminium and carbon fibre
0:15:05 > 0:15:08making the game faster and more precise than ever.
0:15:09 > 0:15:12But this racket, from French company Babolat, has gone further.
0:15:12 > 0:15:14It's also a virtual coach.
0:15:14 > 0:15:19It analyses your moves, and collects information while you play.
0:15:19 > 0:15:21To keep within the International Tennis Federation rules,
0:15:21 > 0:15:24the data can only be accessed afterwards.
0:15:25 > 0:15:28Once synced via USB with a laptop
0:15:28 > 0:15:30or in this case Bluetooth to a phone,
0:15:30 > 0:15:32the racket gives a post-match analysis.
0:15:32 > 0:15:35It shows how long you've played, how many forehands and backhands
0:15:35 > 0:15:37you've hit, that sort of thing,
0:15:37 > 0:15:39but it also says exactly where on the racket
0:15:39 > 0:15:42you're hitting, and how much spin you're putting on the ball -
0:15:42 > 0:15:45presumably to help players modify their style
0:15:45 > 0:15:47once they see the readings.
0:15:47 > 0:15:49And, there's a social element to the app.
0:15:49 > 0:15:54Here, my score is compared with top player Rafael Nadal.
0:15:54 > 0:15:57Unsurprisingly, his score is a little higher than mine.
0:15:59 > 0:16:02Back to Spen.
0:16:02 > 0:16:07LJ Rich. Now, as smartphone processes get faster and more powerful,
0:16:07 > 0:16:10one of the other technologies that needs to keep up is the storage.
0:16:10 > 0:16:13As you take videos and photos with for example
0:16:13 > 0:16:17this ring of smartphones, they have to write to their storage incredibly quickly,
0:16:17 > 0:16:20and one of the things that SanDisk is showing off with this
0:16:20 > 0:16:24ring of beauties is just how fast these cameras can catch the photo.
0:16:24 > 0:16:26For example, if I turn around
0:16:26 > 0:16:28you get this effect.
0:16:28 > 0:16:32Now, to be honest this should have been something a little more like
0:16:32 > 0:16:34The Matrix's bullet time effect
0:16:34 > 0:16:37but due to shall we say network problems,
0:16:37 > 0:16:40a lot of the cameras failed.
0:16:40 > 0:16:41It worked for other people,
0:16:41 > 0:16:44but after two days of trying to rescue MY footage
0:16:44 > 0:16:46the Hollywood studio behind the prototype
0:16:46 > 0:16:49had to go a little off-grid.
0:16:49 > 0:16:53I do feel like I'm in The Matrix - just not in the way I expected.
0:16:56 > 0:17:00And if you thought that was eye-popping, here comes Jen Copestake
0:17:00 > 0:17:03with something that most definitely isn't.
0:17:14 > 0:17:19Many people worry about the effects staring at a phone or tablet
0:17:19 > 0:17:21for hours on end can have on the eyes.
0:17:21 > 0:17:24But a new app aims to change your perspective.
0:17:25 > 0:17:28The Ultimeyes app claims to help you see further
0:17:28 > 0:17:31and sharper than before you used it.
0:17:31 > 0:17:35It uses simple puzzles that activate the visual cortex in your brain,
0:17:35 > 0:17:37which controls eyesight.
0:17:37 > 0:17:41The app features a series of fuzzy target blobs you click on,
0:17:41 > 0:17:45which become harder to see as the game progresses.
0:17:45 > 0:17:49The game is targeting your brain, not your eye muscles,
0:17:49 > 0:17:51and works on new research into how the brain
0:17:51 > 0:17:54can be fundamentally rewired through exercise.
0:17:54 > 0:17:58For years we've known that if you exercise your body,
0:17:58 > 0:18:01it could be stronger and you could do better at the things you do.
0:18:01 > 0:18:06And now it's more and more the case that we know how to do this
0:18:06 > 0:18:09with the brain, and so I'm excited about trying to make
0:18:09 > 0:18:13tools that will be generally promoting mental fitness.
0:18:13 > 0:18:16Ultimeyes was tested by 19 baseball players,
0:18:16 > 0:18:19who used it 30 times in 25-minute intervals.
0:18:19 > 0:18:22The distance at which they could see clearly
0:18:22 > 0:18:26was lengthened by an average of 31% after using it.
0:18:26 > 0:18:31Seven of the players achieved a remarkable 20/7.5 vision,
0:18:31 > 0:18:37meaning they could see at 20 feet what someone with normal eyesight can see at 7.5.
0:18:37 > 0:18:40Don't expect that if you just do the programme for 25 minutes
0:18:40 > 0:18:42your vision's going to suddenly be better.
0:18:42 > 0:18:44Prolonged exercise is required,
0:18:44 > 0:18:48and typical studies in perceptual learning
0:18:48 > 0:18:50require weeks and months of training,
0:18:50 > 0:18:54and if you want to really get changes that are going to
0:18:54 > 0:18:57make you be able to see a line or two lower on an eye chart,
0:18:57 > 0:18:59you really need to work at this.
0:18:59 > 0:19:03I'll be honest, it takes a lot of patience to get through the sessions.
0:19:03 > 0:19:05The research into whether or not this app
0:19:05 > 0:19:08will have any significant long-term effects is exciting,
0:19:08 > 0:19:12but whether it can be replicated with a bigger sample remains to be seen.
0:19:14 > 0:19:17Jen Copestake, going easy on her eyes.
0:19:17 > 0:19:19And just as we're getting used to touching
0:19:19 > 0:19:21and swiping our gadgets,
0:19:21 > 0:19:23devices like Xbox Kinect have introduced us
0:19:23 > 0:19:28to a whole new way to control them. Gesture.
0:19:28 > 0:19:30And if your device doesn't come with gesture recognition,
0:19:30 > 0:19:32or even touch for that matter,
0:19:32 > 0:19:37then Israeli outfit eyeSight can retrofit it with special software.
0:19:37 > 0:19:40Apps for Apple and Android devices use the front-facing camera
0:19:40 > 0:19:43to watch out for your waggles, and then convert them
0:19:43 > 0:19:46into their respective touch command.
0:19:46 > 0:19:50This PC's webcam can do all that and spot special gestures,
0:19:50 > 0:19:52allowing you to mute your music
0:19:52 > 0:19:54with a simple shush.
0:19:54 > 0:19:57OK - next up, it's Kate Russell, with Webscape.
0:20:02 > 0:20:07It's thought that by 2016 one-third of the planet's 7 billion people
0:20:07 > 0:20:09will be using social media.
0:20:09 > 0:20:13For a more efficient way to talk to them, try Buffer.
0:20:13 > 0:20:16This publishing tool lets you manage all your key accounts
0:20:16 > 0:20:18through one simple dashboard,
0:20:18 > 0:20:21with built-in analytics to help you see which content
0:20:21 > 0:20:23is most engaging for your followers.
0:20:29 > 0:20:34It's not uncommon to have more than one social media account for different purposes -
0:20:34 > 0:20:38LinkedIn for business, Twitter for random link sharing,
0:20:38 > 0:20:43Facebook and Google+ for longer conversations and keeping up with the family -
0:20:43 > 0:20:47but you don't want to spend too much time keeping them all updated.
0:20:47 > 0:20:52After all - you have a real life to live as well as an online one, right?
0:20:53 > 0:20:57You can choose which networks to share stuff on, and even schedule
0:20:57 > 0:21:01those posts to happen at times when your followers are most active.
0:21:01 > 0:21:03Browser extensions in various flavours
0:21:03 > 0:21:06are a brilliant time-saving addition,
0:21:06 > 0:21:09and there's loads of other popular integrations
0:21:09 > 0:21:11like If This Then That and Trapit,
0:21:11 > 0:21:14to make sharing fantastic content even easier.
0:21:15 > 0:21:19Another useful app if you want to know what's around you
0:21:19 > 0:21:22is World Around Me, on IoS and Android.
0:21:22 > 0:21:25The lite motion is free and ad-supported,
0:21:25 > 0:21:29using augmented reality to put a label on your camera viewpoint
0:21:29 > 0:21:34for attractions like restaurants, hotels and other useful amenities.
0:21:49 > 0:21:52If you want to get really serious about finding your way about
0:21:52 > 0:21:56in a strange place, though, you could hire a local guide.
0:21:56 > 0:21:59Dopios is a community site that allows travellers
0:21:59 > 0:22:02to search for local guides by destination,
0:22:02 > 0:22:06and then filter the results by the kinds of things they like to do.
0:22:07 > 0:22:11So, if you like going to museums and looking at dinosaur bones
0:22:11 > 0:22:15you can choose someone who knows all the best historic sites.
0:22:15 > 0:22:19Or, if you're more inclined to spend your time shopping, you can
0:22:19 > 0:22:23pick the perfect partner to show you around the retail hotspots.
0:22:23 > 0:22:26And this means you can make sure you get the best host
0:22:26 > 0:22:29possible for your trip, whatever you like to do.
0:22:34 > 0:22:39From art lovers to techies, foodies or the outdoors type,
0:22:39 > 0:22:41each guide lists the tours they offer,
0:22:41 > 0:22:44and the website checks and verifies them
0:22:44 > 0:22:46to make sure everyone is kept safe.
0:22:46 > 0:22:48You can sign up to be a guide as well
0:22:48 > 0:22:51if you think you have something to offer, which could be a nice way
0:22:51 > 0:22:56to earn a little extra money, just showing visitors around town.
0:23:00 > 0:23:02Kate Russell's Webscape.
0:23:02 > 0:23:06And just before we leave the Mobile World Congress for this year,
0:23:06 > 0:23:10how about this as an idea for a future mobile application?
0:23:10 > 0:23:12You've driven to work, parked your car in the car park
0:23:12 > 0:23:15and then you remember you've forgotten to buy the milk.
0:23:15 > 0:23:18Well, you go online, you do your shopping,
0:23:18 > 0:23:22and Enrico turns up, with his shopping bike.
0:23:22 > 0:23:24By pressing a button on a special app on his tablet
0:23:24 > 0:23:28he makes your car flash so he can find it.
0:23:28 > 0:23:31With a second press of the button, he unlocks your boot,
0:23:31 > 0:23:36and then he can pop your shopping in there while you're still at work.
0:23:36 > 0:23:39Closes the boot and then with a third press,
0:23:39 > 0:23:42he can lock your car again.
0:23:42 > 0:23:44This is possible on Volvo cars at the moment
0:23:44 > 0:23:48because many Volvo cars are already connected to the internet, and that is an idea...
0:23:48 > 0:23:51- BICYCLE BELL TINGS - ..ting-a-ling yourself...
0:23:51 > 0:23:56for the ultimate mobile shopping experience.
0:23:56 > 0:23:59And that really is it from Click in Barcelona.
