:00:00. > :00:18.This week: smoking streets, burning fruit and keeping our cool as we go
:00:19. > :00:51.live in virtual reality. We are about to put a whole new spin
:00:52. > :00:57.on the world of mobiles. We are at the Mobile world Congress in
:00:58. > :01:05.Barcelona devoted to phones, tablets and all things mobile. Although, if
:01:06. > :01:11.we look a bit distract the it is because we are preparing for a
:01:12. > :01:15.rather audacious experiment. It is not that we are not interested in
:01:16. > :01:24.the floating displays, flash cars, smart shoes all robot drones, it is
:01:25. > :01:29.just that we are about to bash out something a lot more complicated.
:01:30. > :01:33.Last year we found an entire programme in 360 degrees allowing
:01:34. > :01:38.those watching to look around the fantastic locations simply by
:01:39. > :01:46.turning their heads in whichever direction they please. That is the
:01:47. > :01:53.power of 360, you feel like you have been teleported into the situation.
:01:54. > :01:58.We also have the ability to stream 360 live so imagine that, the next
:01:59. > :02:04.time we send a robot to the men if it has a 360 camera on board, we can
:02:05. > :02:10.put on a pair of goggles and feel like we are there as well. So that
:02:11. > :02:15.is what we doing today, ready to go live in a 360, not to the men
:02:16. > :02:23.admittedly, but to a place that is still a pretty strange landscape.
:02:24. > :02:26.Here we are at the MWC. Enormous homes of madness and noise as
:02:27. > :02:32.everyone tries to launch their products with maximum pizzazz and
:02:33. > :02:39.volume. This event is not just about mobiles, virtual reality is
:02:40. > :02:48.everywhere. Since you can use the phone as a VI said, many strap
:02:49. > :02:58.people in and held them about. VI can be totally immersive if you have
:02:59. > :03:04.your rain 360 chair. -- your very. I do not want to think what kind of
:03:05. > :03:11.experience this chap is having. It is more about the camera equipment
:03:12. > :03:18.you can and cannot use. You are currently watching it through a
:03:19. > :03:26.Nokia professional 360 camera worth about 45,000 US dollars but it is a
:03:27. > :03:32.beautiful looking thing. It has at lenses so you can see in all
:03:33. > :03:36.directions but also shoot in 3-D because the combination of lenses
:03:37. > :03:43.allows that. What is really weird is it has this enormous battery pack.
:03:44. > :03:52.This thing has a blind spot to about here. Said they have this almost 360
:03:53. > :03:58.view and stretch it around. Modern cameras will stitch the scene
:03:59. > :04:03.together, automatically wrapping the weird video into a sphere around
:04:04. > :04:11.your head and that is what enables them to go live. If you wanted to
:04:12. > :04:18.stream the full 360 view, you are going to need some extract it.
:04:19. > :04:25.Hardware boxes and Internet speed. In a trade show like this, we are
:04:26. > :04:29.not that lucky. The thing we have to accept in the early days is that to
:04:30. > :04:34.get really high-quality, stereoscopic video, so you can
:04:35. > :04:39.really look around and feel a sense of depth, it is going to take a
:04:40. > :04:45.while. There are bandwidth problem and just having equipment that can
:04:46. > :04:50.transmit and that amount of data, when you look, the picture gets
:04:51. > :04:56.rendered exactly where you are looking. It will take a while but we
:04:57. > :05:00.are starting. We are going to be doing two lives, testing to
:05:01. > :05:05.different cameras and this is no mean feat because as with last year,
:05:06. > :05:11.we are coming to this before the manufacturers have made bespoke
:05:12. > :05:16.equipment. To get the picture, sound and interaction, we have to pack
:05:17. > :05:22.together various bits and hope no one trips over. My microphone goes
:05:23. > :05:27.into a transmitter which goes into a receiver which goes into a box which
:05:28. > :05:35.plugs into another box and another mile of Internet cable which is
:05:36. > :05:43.going to a network access point here than in the garden. The first camera
:05:44. > :05:51.is for lenses which between them can shoot in whole trial higher. --
:05:52. > :05:58.ultrahigh. The viewer only sees are part of these as they look around
:05:59. > :06:07.the scene. At the moment, it is not showing us anything we have. We are
:06:08. > :06:13.a bit blurry in London. It was our very first attempt so things were
:06:14. > :06:24.bumpy and rough around the edges. -15 minutes ago we were supposed to
:06:25. > :06:29.go. We are going live now. That said, it seemed to hang together and
:06:30. > :06:33.viewers on our you cheap 360 channel got to find out a bit more about a
:06:34. > :06:46.car planning to go at a house in miles per hour. Three engines. To
:06:47. > :06:54.name on jets. Rockets. And you need three of them. To get to 1000 miles
:06:55. > :06:59.an hour. The gas turbine is for your manoeuvres and then the rockets fire
:07:00. > :07:04.you up to give you the kick to over a thousand. Streaming such a
:07:05. > :07:09.high-quality picture takes a lot of data hence we have to use that why
:07:10. > :07:20.Internet connection but for our second attempt, we went commando.
:07:21. > :07:29.The Ricoh camera is the one we used to shoot the helicopter scene last
:07:30. > :07:34.year. It is only to Kate, same as a high-definition picture but what you
:07:35. > :07:37.see is much lower resolution but it means it is possible to stream the
:07:38. > :07:46.video live over the mobile network which is what we did, in style, with
:07:47. > :07:56.a drone. A taste of what it is like to be so close to a drome, you might
:07:57. > :08:02.lose a limb. Weird. Very soon, Ricoh is releasing an update with more
:08:03. > :08:06.connectors, expandable storage and it will do the stitching in the
:08:07. > :08:13.camera itself rather than needing a computer. For now, we were pretty
:08:14. > :08:17.happy with our experiment and very soon there will certainly be more
:08:18. > :08:27.fully integrated chips to let us go live in 360 with much less bother.
:08:28. > :08:34.When we went to film the collider, we had to stitch the footage
:08:35. > :08:41.together manually, using a powerful computer and software and many, many
:08:42. > :08:49.hours. Since then, that cases been released. It has one remote. It also
:08:50. > :08:53.comes with a box that does all the stitching. In a couple of months, it
:08:54. > :09:00.will release an update which allows you to do that live. And if you want
:09:01. > :09:07.to create your 360, this tiny camera plugs into your Android phone. The
:09:08. > :09:12.videos are not live but the stitching is quick and you can share
:09:13. > :09:21.it easily on your social network. Anyway, in a 360! Let's see some
:09:22. > :09:26.phones. -- enough 360! A couple of years ago we got to play with the
:09:27. > :09:30.Sony camera which could shoot video in super slow motion and we
:09:31. > :09:36.discovered that everything looks cool when it is filmed 40 times
:09:37. > :09:41.slower... Well, almost everything. So it is not real surprise that
:09:42. > :09:53.technology has been shut down and down and made its way into a phone.
:09:54. > :09:59.This is the new Sony premium and it can feel at 960 frames her second.
:10:00. > :10:06.Which is great news for glitter borders everywhere. To do this, Sony
:10:07. > :10:14.has had to invent some super fast storage into the image processor
:10:15. > :10:18.itself. The problem is, because there is only so much space, you are
:10:19. > :10:28.limited to only short bursts of slow Mo every few seconds within your
:10:29. > :10:32.video. It is right when you want to catch something in super slow motion
:10:33. > :10:36.that is going on for a long time, like this. Not when you want to
:10:37. > :10:43.catch something that only happens once at a split-2nd, it is quite
:10:44. > :10:52.nerve racking. Case in point, setting fire to render zest which I
:10:53. > :11:03.did not even know was a thing. That is a problem. The bursts of super
:11:04. > :11:07.slow Mo is zero point one eight to second said you have to be spot on
:11:08. > :11:19.with your timing. For the most part, I was a bit too trigger happy but
:11:20. > :11:26.when you do get it, flaming oranges! It is worth bearing in mind that
:11:27. > :11:30.Sony makes the camera parts for many other mobile phones. If this catches
:11:31. > :11:36.on, we could well see it in other phones before Toulon. What else is
:11:37. > :11:48.hot here? Let's have a round-up Stephen. Incredibly, at the
:11:49. > :11:54.convention this is a phone everybody was talking about. It has
:11:55. > :12:04.resurrected a scintillating piece of nostalgia in the Nokia 3310. Do you
:12:05. > :12:09.remember that? Close to indestructible, seemingly infinite
:12:10. > :12:14.batch we live, it now has modern curves, jazzy colours and a new
:12:15. > :12:23.version of snake. That we has also going back to basics. It has a
:12:24. > :12:30.physical gesture sensitive keyboard. That is the only nostalgia here,
:12:31. > :12:36.this classic Norris pencil although I would not sharpen it because there
:12:37. > :12:42.is quite a lot of digital stuff in the end to allow you to do things
:12:43. > :12:48.like this. Google would much rather cute talk to your devices. Google
:12:49. > :12:53.home will finally be available for sale outside of the US and Jaime in
:12:54. > :13:02.the UK. The company also said it will roll out its digital assistant
:13:03. > :13:10.to mobile phones running marshmallow and nougat. That is a part from
:13:11. > :13:19.these two mobiles, set to use and is on at instead. It would get its
:13:20. > :13:23.assistance smart through a snap on back. Others are ditching
:13:24. > :13:30.customisation. LG launched a new phone without the capability of its
:13:31. > :13:40.previous mobile. Customers do not fancy art forking out more. The
:13:41. > :13:46.screen is twice as tall as wide. And it would not be much of a round-up
:13:47. > :13:53.without at least one mention of the words - five G. Even a standard
:13:54. > :14:00.exists, it hasn't stopped anyone here from seeking the term all over
:14:01. > :14:09.the stands. Nowhere more than here. You can see the numbers ticking
:14:10. > :14:13.away. Sucking up data 50 times faster than your four D phone. We
:14:14. > :14:17.are not allowed to touch or use of these phones and that could have
:14:18. > :14:22.something to do with all the cables. It could be some time yet before you
:14:23. > :14:26.get your hands on these sorts of speeds.
:14:27. > :14:34.Over the past few years, the air that we breathe in our cities has
:14:35. > :14:37.become a big issue. Air pollution is an invisible killer and it is
:14:38. > :14:42.something that many people from politicians to take companies still
:14:43. > :14:46.needs urgent attention but what to do? All next week, the BBC is going
:14:47. > :14:51.to be looking at the issue and possible solutions in the Mac so I
:14:52. > :14:55.can Breathe serious. We'll be looking at some of the gadgets that
:14:56. > :15:03.might help us to track the pollution around us so we know what to do with
:15:04. > :15:08.that data. It only took five days this year for London to reach its
:15:09. > :15:13.yearly air pollution allowance. People were warned to reduce out
:15:14. > :15:19.your physical exercise as levels soared beyond those in Beijing. A
:15:20. > :15:24.place where scenes like this are not unusual. And with limits being
:15:25. > :15:29.exceeded in Germany, France, Italy, Spain, as well as other cities
:15:30. > :15:35.across the UK, never before have we been so aware of the air we breathe.
:15:36. > :15:40.Yet, if they are better or worse days of better routes that you could
:15:41. > :15:45.take them could using a personal air quality tracker help you make better
:15:46. > :15:49.decisions about what to do, when? First of all, it depends how
:15:50. > :15:55.accurate they are and that is something I am on a mission to find
:15:56. > :15:59.out about. The makers of some of these devices say they have gone
:16:00. > :16:03.through extensive testing over a long period. While our spot checks
:16:04. > :16:08.today are just a snapshot, I am curious to find out how they measure
:16:09. > :16:11.up. To carry out our first experiment, I have come to this
:16:12. > :16:15.central London amused and I have enlisted the help of the University
:16:16. > :16:20.of Birmingham who for fairness of the experiment have brought along
:16:21. > :16:24.this which is going to take some pretty serious recordings of their
:16:25. > :16:32.quality along with my four devices here to see how they do. This tube
:16:33. > :16:43.can be attached to a bag to track the OC as well as carbon monoxide.
:16:44. > :16:47.-- VOC. It tracks carbon monoxide and at a personal and crowd sourced
:16:48. > :16:53.element to the critical data it already displays. This is smart
:16:54. > :17:03.phone case has an air quality sensor tracker linked -- tracking VOCs. And
:17:04. > :17:08.this one called Plume will work alongside the apps. It tracks
:17:09. > :17:15.nitrogen oxide and VOCs eventually looking at particular matter and O
:17:16. > :17:19.zone two. They are also available for indoor monitoring. I have given
:17:20. > :17:24.them five minutes to do their thing but at the moment it is a bit of a
:17:25. > :17:27.sea of numbers. That I have found a man to find out what this means. I
:17:28. > :17:32.am joined by Professor Roy Harrison from the University of Birmingham.
:17:33. > :17:35.What is going on? We are getting different readings but they'll
:17:36. > :17:39.should be giving us the same impression of the pollution. And
:17:40. > :17:48.this is where the fun begins. Let's look at our first device. This is
:17:49. > :17:53.the Atmo Tube. Jono it is looking at 0.22 ppm of which is saying it is
:17:54. > :17:58.good at quality. 93 out of 100 so things are pretty clean, this one
:17:59. > :18:02.says. This will be mostly coming from traffic. Indoors, there are
:18:03. > :18:06.other sources but now we are outdoors. Comparing that to your
:18:07. > :18:13.readings, are they on track? I would say that our reason it -- our
:18:14. > :18:17.reading is different pollutant but rather more polluted than the 93 out
:18:18. > :18:24.of 100. I wouldn't call it good, I would call the air quality average.
:18:25. > :18:28.This one is reading carbon monoxide. It is giving us concentrations that
:18:29. > :18:34.appeared to be a little bit above 1.5 parts per million. That would be
:18:35. > :18:42.consistent with what we are seeing in the nitrogen. -- nitrous dioxide.
:18:43. > :18:47.That in a sense is a more predictable sense with the ones
:18:48. > :18:51.depending on the organic compounds because that is a big range of
:18:52. > :19:01.substances and the sensitivity will not be the same for every compound.
:19:02. > :19:06.Then we are looking at the i-Blades phone case. It is calling this
:19:07. > :19:13.street zero which is a funny way to work. I think it is. Ideally it
:19:14. > :19:17.needs to be zero in a clean atmosphere but if you don't have an
:19:18. > :19:22.independent monitor, how do you know where the clean atmosphere is? I
:19:23. > :19:23.have a bit of difficulty with this one. The final one
:19:24. > :19:48.we have is Flow by Plume. Sensor is looking at correlating with our
:19:49. > :19:56.device in the car. It is telling us that the pollution level is high. I
:19:57. > :19:59.understand that that is a judgement against health -based standards from
:20:00. > :20:04.the World Health Organization. I do find a little bit surprising because
:20:05. > :20:13.I wouldn't regard the levels here is high and certainly not as a
:20:14. > :20:17.particular health risk, for example. For the second part of our
:20:18. > :20:22.experiment, we have come to a somewhat busier street. They could
:20:23. > :20:25.street, the home of Sherlock Holmes were our investigation shall
:20:26. > :20:31.continue, Professor. The readings are changing. What you make things?
:20:32. > :20:35.Well, it is a busy street. Our reference analyser in the car is
:20:36. > :20:42.looking at concentrations about double of those we are reading in
:20:43. > :20:46.the news or three times higher. White Atmo Tube registers are rising
:20:47. > :20:54.pollution but still kept -- calls the air quality good. The i-Blades
:20:55. > :20:57.case rose from zero and Flow by Plume and simply says high. There is
:20:58. > :21:01.an argument from some bat by tracking this data and taking
:21:02. > :21:04.control ourselves, we are diminishing the government's
:21:05. > :21:09.responsibility to actually improve the situation but what does our
:21:10. > :21:13.scientist walk away from our day's activity thinking? They are very
:21:14. > :21:17.variable in their performance. One could try and use them to judge
:21:18. > :21:22.which routes were the best ones if one was walking to work, for example
:21:23. > :21:25.but that would not be a simple button because the pollution levels
:21:26. > :21:31.change from day to day raised on the weather so you need to do the
:21:32. > :21:35.different routes many times in order to get them representative at
:21:36. > :21:39.looking at the actual pollution levels but I suspect the answer will
:21:40. > :21:44.be no better than just looking at the traffic and to say wow, this is
:21:45. > :21:51.a quiet road, why don't you use this one? -- why don't I use this one? I
:21:52. > :21:59.need to run a lot with the devices or keep my eyes open without.
:22:00. > :22:07.That was Lara and a bigger source of air pollution in the developing
:22:08. > :22:12.world at -- is that produced by the burning of kerosene. It is also
:22:13. > :22:16.dangerous and can cause housebuyers. Obviously it would be preferable to
:22:17. > :22:20.move to solar power but are rigged like this costs $200. Something many
:22:21. > :22:27.families cannot make as a single lump sum. This company is suggesting
:22:28. > :22:31.renting a solar system like this with a panel and all this kit to
:22:32. > :22:35.families in return to micro- payments of about 50 cents a day
:22:36. > :22:39.that they can make on the mobile network. Once they pay for the
:22:40. > :22:45.equipment, they get to keep it. If they stop making payments at any
:22:46. > :22:49.point, this box can be contacted over the mobile network and be
:22:50. > :22:53.switched off. A similar scheme is being piloted with gas in Tanzania
:22:54. > :22:58.to try to move people away from cooking with charcoal. Again, the
:22:59. > :23:03.barriers to entry meant buying an exact -- entire gas can it staff is
:23:04. > :23:06.expensive. But this allows micro- payments over mobile which all are
:23:07. > :23:13.small and announced it be released to each person. You can ask to move
:23:14. > :23:14.the metre but if you do it sends an alert to the scheme at's
:23:15. > :23:26.administrators. Here is something else that has
:23:27. > :23:30.impressed us at NWS C. Look at our faces in this picture. This is a
:23:31. > :23:37.phone that was released a couple of months ago that allows you to take
:23:38. > :23:41.three photos. Then you can view the photos in 3-D without glasses on the
:23:42. > :23:45.screen because it has a lenticular display. Which means your left I
:23:46. > :23:49.only get left information and the Right I only get right eye
:23:50. > :23:53.information. If you hold it right at the sweet spots, you get a pretty
:23:54. > :23:57.picture. If you hold it outside the sweet spot, everything goes crazy
:23:58. > :24:05.and I wouldn't recommend that. That is it for Click in the MWC in
:24:06. > :24:09.Barcelona. I hope you enjoy that. Be kind but be honest. Thanks for
:24:10. > :24:28.watching. I will see you soon. For most of us, Friday
:24:29. > :24:32.was a miserable day but, for the favoured few,
:24:33. > :24:34.it was glorious. If you don't believe me, look
:24:35. > :24:38.at the Weather Watchers picture.
