this week: smoking streets, burning fruit and keeping our cool as we go live in virtual reality. we are about to put a whole new spin on the world of mobiles. we are at the mobile world congress in barcelona devoted to phones, tablets and all things mobile. although, if

we look a bit distract the it is because we are preparing for a rather audacious experiment. it is not that we are not interested in the floating displays, flash cars, smart shoes all robot drones, it is just that we are about to bash out something a lot more complicated. last year we found an entire programme in 360 degrees allowing those watching to look around the fantastic locations simply by turning their heads in whichever direction they please. that is the power of 360, you feel like you have been teleported into the situation. we also have the ability to stream 360 live so imagine that, the next time we send a robot to the men if

it has a 360 camera on board, we can put on a pair of goggles and feel like we are there as well. so that is what we doing today, ready to go live in a 360, not to the men admittedly, but to a place that is still a pretty strange landscape. here we are at the mwc. enormous homes of madness and noise as eve ryo ne homes of madness and noise as everyone tries to launch their products with maximum pizzazz and volume. this event is notjust about mobiles, virtual reality is everywhere. since you can use the phone as a vi said, many strap people in and held them about. vi can be totally immersive if you have your rain 360 chair. —— your very. i do not want to think what kind of

experience this chap is having. it is more about the camera equipment you can and cannot use. you are currently watching it through a nokia professional 360 camera worth about 16,000 us dollars but it is a beautiful looking thing. it has at lenses so you beautiful looking thing. it has at lenses so you can see beautiful looking thing. it has at lenses so you can see in all directions but also shoot in 3—d because the combination of lenses allows that. what is really weird is it has this enormous battery pack. this thing has a blind spot to about here. said they have this almost 360 view and stretch it around. modern cameras will stitch the scene together, automatically wrapping the weird video into a sphere around

your head and that is what enables them to go live. if you wanted to strea m them to go live. if you wanted to stream the full 360 view, you are going to need some extract it. hardware boxes and internet speed. ina hardware boxes and internet speed. in a trade show like this, we are not that lucky. the thing we have to accept in the early days is that to get really high—quality, stereoscopic video, so you can really look around and feel a sense of depth, it is going to take a while. there are bandwidth problem and just having equipment that can transmit and that amount of data, when you look, the picture gets rendered exactly where you are looking. it will take a while but we are starting. we are going to be doing two lives, testing to different cameras and this is no

mean feat because as with last year, we are coming to this before the manufacturers have made bespoke equipment. to get the picture, sound and interaction, we have to pack together various bits and hope no one trips over. my microphone goes into a transmitter which goes into a receiver which goes into a box which plugs into another box and another mile of internet cable which is going to a network access point here than in the garden. the first camera is for lenses which between them can shoot in whole trial higher. —— ultrahigh. the viewer only sees are pa rt ultrahigh. the viewer only sees are part of these as they look around the scene. at the moment, it is not

showing us anything we have. we are a bit blurry in london. it was our very first attempt so things were bumpy and rough around the edges. -15 bumpy and rough around the edges. —15 minutes ago we were supposed to go. we are going live now. that said, it seemed to hang together and viewers on our said, it seemed to hang together and viewers on oui’ you said, it seemed to hang together and viewers on our you cheap 360 channel got to find out a bit more about a car planning to go at a house in miles per hour. three engines. to name onjets. miles per hour. three engines. to name on jets. rockets. and you need three of them. to get to 1000 miles an hour. the gas turbine is for your manoeuvres and then the rockets fire you up to give you the kick to over

a thousand. streaming such a high—quality picture takes a lot of data hence we have to use that why internet connection but for our second attempt, we went commando. the ricoh camera is the one we used to shoot the helicopter scene last year. it is only to kate, same as a high—definition picture but what you see is much lower resolution but it means it is possible to stream the video live over the mobile network which is what we did, in style, with a drone. a taste of what it is like to be so close to a drome, you might lose a limb. weird. very soon, ricoh is releasing an update with more

connectors, expandable storage and it will do the stitching in the camera itself rather than needing a computer. for now, we were pretty happy with our experiment and very soon there will certainly be more fully integrated chips to let us go live in 360 with much less bother. when we went to film the collider, we had to stitch the footage together manually, using a powerful computer and software and many, many hours. since then, that cases been released. it has one remote. it also comes with a box that does all the stitching. in a couple of months, it will release an update which allows you to do that live. and if you want to create your 360, this tiny camera

plugs into your android phone. the videos are not live but the stitching is quick and you can share it easily on your social network. anyway, in a 360! let's see some phones. —— enough 360! a couple of yea rs phones. —— enough 360! a couple of years ago we got to play with the sony camera which could shoot video in super slow motion and we discovered that everything looks cool when it is filmed a0 times slower... well, almost everything. so it is not real surprise that technology has been shut down and down and made its way into a phone. this is the new sony premium and it can feel at 960 frames her second. which is great news for glitter

borders everywhere. to do this, sony has had to invent some super fast storage into the image processor itself. the problem is, because there is only so much space, you are limited to only short bursts of slow mo every few seconds within your video. it is right when you want to catch something in super slow motion thatis catch something in super slow motion that is going on for a long time, like this. not when you want to catch something that only happens once at a split—2nd, it is quite nerve racking. case in point, setting fire to render zest which i did not even know was a thing. that isa did not even know was a thing. that is a problem. the bursts of super slow mo is zero point one eight to

second said you have to be spot on with your timing. for the most part, i was with your timing. for the most part, iwasa with your timing. for the most part, i was a bit too trigger happy but when you do get it, flaming oranges! it is worth bearing in mind that sony makes the camera parts for many other mobile phones. if this catches on, we could well see it in other phones before toulon. what else is hot here? let's have a round—up stephen. incredibly, at the convention this is a phone everybody was talking about. it has resurrected a scintillating piece of nostalgia in the nokia 3310. do you

remember that? close to indestructible, seemingly infinite batch we live, it now has modern curves, jazzy colours and a new version of snake. that we has also going back to basics. it has a physical gesture sensitive keyboard. that is the only nostalgia here, this classic norris pencil although i would not sharpen it because there is quite a lot of digital stuff in the end to allow you to do things like this. google would much rather cute talk to your devices. google home will finally be available for sale outside of the us and jaime in the uk. the company also said it will roll out its digital assistant to mobile phones running marshmallow

and nougat. that is a part from these two mobiles, set to use and is on at instead. it would get its assistance smart through a snap on back. 0thers assistance smart through a snap on back. others are ditching customisation. lg launched a new phone without the capability of its previous mobile. customers do not fa ncy previous mobile. customers do not fancy art forking out more. the screen is twice as tall as wide. and it would not be much of a round—up without at least one mention of the words — five g. even a standard exists, it hasn't stopped anyone here from seeking the term all over the stands. nowhere more than here.

you can see the numbers ticking away. sucking up data 50 times faster than your four d phone. away. sucking up data 50 times faster than yourfour d phone. we are not allowed to touch or use of these phones and that could have something to do with all the cables. it could be some time yet before you get your hands on these sorts of speeds. 0ver over the past few years, the air that we breathe in our cities has become a big issue. air pollution is an invisible killer and it is something that many people from politicians to take companies still needs urgent attention but what to do? all next week, the bbc is going to be looking at the issue and possible solutions in the mac so i can breathe serious. we'll be looking at some of the gadgets that might help us to track the pollution around us so we know what to do with that data. it only took five days

this yearfor london that data. it only took five days this year for london to reach its yearly air pollution allowance. people were warned to reduce out your physical exercise as levels soared beyond those in beijing. a place where scenes like this are not unusual. and with limits being exceeded in germany, france, italy, spain, as well as other cities across the uk, never before have we been so aware of the air we breathe. yet, if they are better or worse days of better routes that you could ta ke days of better routes that you could take them could using a personal air quality tracker help you make better decisions about what to do, when? first of all, it depends how accurate they are and that is something i am on a mission to find out about. the makers of some of these devices say they have gone through extensive testing over a

long period. while our spot checks today are just a snapshot, i am curious to find out how they measure up. to carry out our first experiment, i have come to this central london amused and i have enlisted the help of the university of birmingham who for fairness of the experiment have brought along this which is going to take some pretty serious recordings of their quality along with my four devices here to see how they do. this tube can be attached to a bag to track the 0c as well as carbon monoxide. -- voc. it the 0c as well as carbon monoxide. —— voc. it tracks carbon monoxide and ata —— voc. it tracks carbon monoxide and at a personal and crowd sourced element to the critical data it already displays. this is smart phone case has an air quality sensor tracker linked —— tracking vocs. and

this one called plume will work alongside the apps. it tracks nitrogen oxide and vocs eventually looking at particular matter and 0 zone two. they are also available for indoor monitoring. i have given them five minutes to do their thing but at the moment it is a bit of a sea but at the moment it is a bit of a sea of numbers. that i have found a man to find out what this means. i am joined by professor roy harrison from the university of birmingham. what is going on? we are getting different readings but they'll should be giving us the same impression of the pollution. and this is where the fun begins. let's look at our first device. this is the atmo tube. jono it is looking at 0.22 ppm of which is saying it is good at quality. 93 out of 100 so things are pretty clean, this one says. this will be mostly coming

from traffic. indoors, there are other sources but now we are outdoors. comparing that to your readings, are they on track?” outdoors. comparing that to your readings, are they on track? i would say that our reason it —— our reading is different pollutant but rather more polluted than the 93 out of 100. rather more polluted than the 93 out of100. i rather more polluted than the 93 out of 100. i wouldn't call it good, i would call the air quality average. this one is reading carbon monoxide. it is giving us concentrations that appeared to be a little bit above 1.5 parts per million. that would be consistent with what we are seeing in the nitrogen. —— nitrous dioxide. thatin in the nitrogen. —— nitrous dioxide. that in a sense is a more predictable sense with the ones depending on the organic compounds because that is a big range of su bsta nces because that is a big range of substances and the sensitivity will not be the same for every compound. then we are looking at the i—blades

phone case. it is calling this street zero which is a funny way to work. i think it is. ideally it needs to be zero in a clean atmosphere but if you don't have an independent monitor, how do you know where the clean atmosphere is? i have a bit of difficulty with this one. the final one we have is flow by plume. sensor is looking at correlating with our device in the car. it is telling us that the pollution level is high. i understand that that is a judgement against health —based standards from the world health organization. i do

find a little bit surprising because i wouldn't regard the levels here is high and certainly not as a particular health risk, for example. for the second part of our experiment, we have come to a somewhat busier street. they could street, the home of sherlock holmes we re street, the home of sherlock holmes were our investigation shall continue, professor. the readings are changing. what you make things? well, it is a busy street. 0ur reference analyser in the car is looking at concentrations about double of those we are reading in the news or three times higher. white atmo tube registers are rising pollution but still kept —— calls the air quality good. the i-blades case rose from zero and flow by plume and simply says high. there is an argument from some bat by tracking this data and taking

control ourselves, we are diminishing the government's responsibility to actually improve the situation but what does our scientist walk away from our day's activity thinking? they are very variable in their performance. one could try and use them to judge which routes were the best ones if one was walking to work, for example but that would not be a simple button because the pollution levels change from day to day raised on the weather so you need to do the different routes many times in order to get them representative at looking at the actual pollution levels but i suspect the answer will be no better than just looking levels but i suspect the answer will be no better thanjust looking at the traffic and to say wow, this is a quiet road, why don't you use this one? —— why don't i use this one?” need to run a lot with the devices or keep my eyes open without. that was lara and a bigger source of

air pollution in the developing world at —— is that produced by the burning of kerosene. it is also dangerous and can cause housebuyers. 0bviously dangerous and can cause housebuyers. obviously it would be preferable to move to solar power but are rigged like this costs $200. something many families cannot make as a single lump sum. this company is suggesting renting a solar system like this with a panel and all this kit to families in return to micro— payments of about 50 cents a day that they can make on the mobile network. 0nce that they can make on the mobile network. once they pay for the equipment, they get to keep it. if they stop making payments at any point, this box can be contacted over the mobile network and be switched off. a similar scheme is being piloted with gas in tanzania to try to move people away from cooking with charcoal. again, the barriers to entry meant buying an exact —— entire gas can it staff is

expensive. but this allows micro— payments over mobile which all are small and announced it be released to each person. you can ask to move the metre but if you do it sends an alert to the scheme at‘s administrators. here is something else that has impressed us at nws c. look at our faces in this picture. this is a phone that was released a couple of months ago that allows you to take three photos. then you can view the photos in 3—d without glasses on the screen because it has a lenticular display. which means your left i only get left information and the right | only get left information and the right i only get right eye information. if you hold it right at the sweet spots, you get a pretty picture. if you hold it outside the sweet spot, everything goes crazy andi sweet spot, everything goes crazy and i wouldn't recommend that. that is it for click in the mwc in

barcelona. i hope you enjoy that. be kind but be honest. thanks for watching. i will see you soon. good morning. for most of us, friday was a miserable day but, for the favoured few, it was glorious. if you don't believe me, look at the weather watchers picture. not a cloud in the sky hardly. a beautiful day across the far north of scotland. but for most of us it was grey and grim. a lot of heavy rain around and this poor old garden in barnsley, well, that tells the tale, doesn't it, really, and it could be a soggy affairfor some of us over the weekend. but not all the time. there will be some rain around

but some of us could manage to get some dry weather in there as well. particularly when you look at where the low pressure is. it's centred to the north across scotland and circulating around that low on the outer edge there will be some stronger winds but further inland we should get a decent slice of dryer weather. so do try to put that in context. it looks as though scotland, you will have a different day today. there will be a lot of cloud, rain around, snow to the tops of mountains, it will be cold as well. showery outbreaks of rain into northern ireland and a fair amount of cloud across northern england. just head a little further south and first thing on saturday morning it's not a bad start for wales and much of central and southern england. into the far south—west it will be windy and wet at times. the strongest of the winds circulating around the outside edge of that area of low pressure. but a central and eastern parts of england, for you, not a bad day. there should be a decent slice of sunshine coming through.

and, with a little shelter, some sunshine, those temperatures will feel reasonable at around ten or 12 degrees. not so the case with the cloud and rain further north. but it does mean for many of the premiership matches it looks as though it will be a largely dry affair. we could see some showers for the liverpool—arsenal evening kickoff there. now as we move out of saturday, we were talking about the potential for the stormy weather across the alps, still the risk of snow, significant snow to come, but for us a frontal system pushing into the far south—west brings a different story on sunday. for many it will be a pretty grim start to the second half of the weekend with some heavy rain moving its way steadily north and east as we go through the day, and the winds increasing as well. so it'll be a dismal start but a slow improvement, so i suspect for the tottenham match hopefully the bulk of the rain will clear away but sunderland—man city could be a soggy affair. as we move into monday and tuesday it looks as though we will continue to see an unsettled spell of weather.

quite cloudy but largely dry perhaps down to the south. an 11—year—old boy rushed to hospital after his house was struck. it released what was described as a "noxious, nauseating gas". two incidents and 12 victims, including a month—old baby. no doubt, say doctors, it was a chemical weapons attack. we have mainly a section of the respiratory tract, so that some people have breathing problems, like a spasm in an asthma attack, and the majority of the patients have developed different size of blisters, especially in the exposed areas. tonight, the international committee for the red cross said the chemical used was very likely to be mustard gas. is has threatened to use chemical weapons before, but what isn't known is what chemicals they have,
