:00:08. > :00:14.This week new homes and new lives. DIY space battles and hidden
:00:15. > :00:52.figures. Did you see that? EU, shame on you! We are living in
:00:53. > :00:58.interesting times. To many it feels like the world is shifting on its
:00:59. > :01:08.access. Tempers are rising, voices are being raised. And there is
:01:09. > :01:18.movement, political. Ideological. And physical. And this is one of the
:01:19. > :01:22.most divisive issues of the day - how to handle what the UN has cold
:01:23. > :01:29.the largest migration of people since the Second World War. At a
:01:30. > :01:36.migrants? Are they refugees? Should they be welcomed? Should they be
:01:37. > :01:44.turned away? At the Barbican in London and artist is making this
:01:45. > :01:47.nuclear with this work - in coming. He has used a long-range infrared
:01:48. > :01:52.camera to film the arrival of migrants and refugees of camps
:01:53. > :01:58.across Europe. It is actually a military tool that can detect body
:01:59. > :02:07.heat from 30 kilometres away. You can see through smoke and haze day
:02:08. > :02:12.or night. So this is a thermographic camera. In other words, you can
:02:13. > :02:16.actually see people was my body is glowing. A radiant thermal glow. You
:02:17. > :02:24.cannot really see their faces. It kind of a non- Isa 's people. It is
:02:25. > :02:29.an image of an individual with out a biological traits. It dehumanises a
:02:30. > :02:39.person, in a way, which is appropriate since it is a weapons
:02:40. > :02:43.grade technology. One interesting result of using a thermal imaging
:02:44. > :02:51.camera is that you cannot tell the skin colour of the people in the
:02:52. > :02:58.film. They are simply people. And of course that is part of this point.
:02:59. > :03:03.He says he wants to use the technology against itself, showing
:03:04. > :03:08.that the same camels that allow missiles to see can also emphasise
:03:09. > :03:14.the fact that all humid life gives off the same glow. We have to work
:03:15. > :03:17.with these people as humans. Instead our governments have created these
:03:18. > :03:23.extraordinary technologies to enforce those borders. So I guess I
:03:24. > :03:28.wish people would dwell on that gullible bit. Germany is one country
:03:29. > :03:33.that has taken on hundreds of thousands of refugees. Many travel
:03:34. > :03:39.to the country from Syria after hearing about its opendoor policy in
:03:40. > :03:42.the summer of 2015. But successfully integrating asylum seekers into
:03:43. > :03:48.society here is still one of the many challenges facing the nation.
:03:49. > :03:50.There are many obstacles to integration, including finding
:03:51. > :03:54.housing and getting a job and learning the language. But
:03:55. > :04:00.technology may help to speed the process. We have been to Berlin,
:04:01. > :04:11.which is now home to over 60,000 Syrian refugees, to see how. When
:04:12. > :04:17.the refugee crisis began, some of Germany's largest empty buildings
:04:18. > :04:21.were given over to how is refugees. Including the International Congress
:04:22. > :04:28.Centre. It was abandoned for conferences and home to over 450
:04:29. > :04:32.guests. 80 people live together in each of these spaces, colourful
:04:33. > :04:35.boxes lining a whole. Most are from Syria but there are asylum seekers
:04:36. > :04:44.from other countries as well. Afghanistan. Rush hour. Pakistan.
:04:45. > :04:52.Ideally, guests only stay here for a few weeks but many people have lived
:04:53. > :04:58.here for over a year. I first heard about this camp when I was covering
:04:59. > :05:03.Europe's biggest tech show. I was surprised to learn that there had
:05:04. > :05:10.been people living in the halls here as well, even recently. In fact hold
:05:11. > :05:14.26 used to housed refugees who have moved out since the conference
:05:15. > :05:18.started. The juxtaposition between a refugee camp in a high-tech trade
:05:19. > :05:21.show cold struck me. But many refugees have been helped by
:05:22. > :05:26.technology, using Internet and smartphones to guide their journey
:05:27. > :05:29.to Germany. Including this man, a programmer from Damascus to spend
:05:30. > :05:37.ten days travelling to Germany from Turkey and was filmed for a TV
:05:38. > :05:41.Channel. He graduated as a computer engineering 2010 and arrived Germany
:05:42. > :05:49.in 2014. I was a little disappointed because I thought I would find big
:05:50. > :05:55.technical companies and I would directly find a job and work but it
:05:56. > :06:10.was not like that. I needed about ten months to discover a position.
:06:11. > :06:14.It takes a few dozen refugees each semester, this course. The school
:06:15. > :06:19.was heavily supported by Facebook who donated space. Mark Zucker Bird
:06:20. > :06:27.and this wife visited the students recently. Through this place a web
:06:28. > :06:36.was -- and app was developed for newcomers. This is the people who
:06:37. > :06:39.speak Arabic so they do not suffer like me in the beginning. They can
:06:40. > :06:49.directly access all the information that they need. He won an award for
:06:50. > :06:52.this work and is entering an entrepreneurship scholarship for six
:06:53. > :07:00.months. In Berlin, finally I found my dream that I can take courses and
:07:01. > :07:04.connect with a lot of companies. I can enter the tech community here in
:07:05. > :07:10.this country. It was not easy to find that in the beginning. For many
:07:11. > :07:12.newcomers, the legal requirement to learn German is one of the hardest
:07:13. > :07:27.hurdles to integration. Outside the class, students can use
:07:28. > :07:34.one of these crime books donated by Google. Felix helped to build a
:07:35. > :07:40.Wi-Fi network here, which was non-existent. This is the server, a
:07:41. > :07:44.little further. It controls who was allowed to get on the Internet and
:07:45. > :07:50.who is not allowed. The crime books are allowed to be taken out five
:07:51. > :07:54.evenings a week and are controlled by a password which changes hourly.
:07:55. > :07:59.If anybody does something wrong we can tell the government. We are not
:08:00. > :08:08.bad people. This guy was a bad person. This distinction is
:08:09. > :08:11.important in Germany where regulation makes the owner of a
:08:12. > :08:18.Wi-Fi network liable for any activity. Muhamed from Syria found
:08:19. > :08:21.it difficult to get online when he arrived in Berlin and had a very
:08:22. > :08:26.different experience in this shelter. We have computer rules,
:08:27. > :08:30.free computers for 400 people and you needed an appointment to go and
:08:31. > :08:36.use one of them. You have to deal with security and if they are not in
:08:37. > :08:43.a good mood they will give you an appointment as after two weeks. If I
:08:44. > :08:48.want to use the Internet, I can't. He joined a group of activists who
:08:49. > :08:53.installed Routers across the cities which can connect refugee housing to
:08:54. > :09:02.the Internet for free. That is where we like to install our networks, at
:09:03. > :09:11.homes or churches. I went to see one of the installations on top of the
:09:12. > :09:14.church tower. Nodes are routed through virtual private servers
:09:15. > :09:21.which gets around some of the laws. This is a nano station antenna,
:09:22. > :09:27.regular five gigahertz financial Wi-Fi network like you would have at
:09:28. > :09:32.home. Somewhere like this where there are no inhibiting factors,
:09:33. > :09:40.this can reach for several kilometres. Cisco, one of the
:09:41. > :09:45.world's largest network provider saw an opportunity where is refugees had
:09:46. > :09:48.online access they could connect to courses already available in their
:09:49. > :09:55.language. Its campus in Berlin comes complete with an autonomous bus. It
:09:56. > :10:01.is also home to a familiar face. We first saw this man last year when we
:10:02. > :10:05.were filming in a camp in Jordan. He had lost this leg in an explosion in
:10:06. > :10:12.Syria. He was volunteering in Jordan with a start-up refugee app to print
:10:13. > :10:17.a cheap replacement parts. He made the difficult decision to travel to
:10:18. > :10:22.Berlin. He is now in Cisco training to be an engineer. It was amazing
:10:23. > :10:29.for me. This building from outside, so old and on the inside it is
:10:30. > :10:33.filled with technology, cutting-edge technology. When I realised that
:10:34. > :10:39.this would be my workspace I was even more excited. He spent this
:10:40. > :10:44.weekends teaching a robotics course for children. It is a nice and fun
:10:45. > :10:49.way to introduce programming to children. Cisco is currently working
:10:50. > :10:53.with five refugee interns and would like to expand the programme. They
:10:54. > :10:56.see the influx of Syrians as an opportunity to fill demand for
:10:57. > :11:02.programming skills in the country. Where would you see him after this
:11:03. > :11:07.programme? I would love to have him in the innovation Centre because at
:11:08. > :11:11.the moment I have a lot of different topics that I want to establish and
:11:12. > :11:16.I would love him to engaging with our customers and the solutions.
:11:17. > :11:22.Even then, in our future. Never have an issue of how to handle a refugee
:11:23. > :11:25.crisis been more controversial. By opening its borders, Germany is at
:11:26. > :11:29.the forefront of this debate. And it is clear that the tech community has
:11:30. > :11:37.a role to play and can help ease the transition to a new home. Hello and
:11:38. > :11:41.welcome to the week in Tech. It was the week that Uber found itself
:11:42. > :11:46.under fire after a former employee accused the company of sexual
:11:47. > :11:50.harassment in a blog post. Uber responded saying it would conduct an
:11:51. > :11:54.urgent investigation into the claims which it cold abhorrent and against
:11:55. > :11:59.everything Uber stands for and believes in. It was also the week
:12:00. > :12:06.that YouTube announced it would get rid of an skippable ads in 2018.
:12:07. > :12:10.Scientists showed off a special coating making it easier to get
:12:11. > :12:13.catch about of a bottle. And astronomers have discovered seven
:12:14. > :12:18.sized planets orbiting a single star. And, before you live, three of
:12:19. > :12:22.them may have conditions to support life. If you just hate living in a
:12:23. > :12:27.world with wires then research may have the answer. Their prototype
:12:28. > :12:34.living room can wisely charge ten items such as smart phones and fans
:12:35. > :12:38.by static have the resonance. This means you can walk around while
:12:39. > :12:42.powering up, the purpose-built room has walls, ceiling and a floor may
:12:43. > :12:47.develop many with a copper pipe in the middle, a signal outside and a
:12:48. > :12:53.power amplifier so not quite a simple DIY job. And finally,
:12:54. > :12:59.researchers at Brigham Young University have shown off an origami
:13:00. > :13:04.inspired light weight bullet-proof pillow. The Barrier is made up of 12
:13:05. > :13:16.layers of bullet-proof Kevlar and weighs only ?55.
:13:17. > :13:31.How many faces can you see in this picture? Did you see that? This is a
:13:32. > :13:39.persistence of vision display. You can only see it when your eyes, or
:13:40. > :13:44.in our case the camera, move left or right. We've slowed right down so
:13:45. > :13:50.you can really feast on... Uh... My face. So, persistence of vision
:13:51. > :13:55.display is predicated upon the persistence of vision for which is
:13:56. > :13:59.an effective human eye and it is the effect where when you look at any
:14:00. > :14:03.bright light and you look away you see a ghost of that bright light for
:14:04. > :14:06.a moment. So what happens is our display takes a standard
:14:07. > :14:10.2-dimensional image and Brexit up in the vertical columns. This single
:14:11. > :14:15.column of light brings out each eye, until it gets to the end of the
:14:16. > :14:19.image and start over. So as your eye looks away from the display, it
:14:20. > :14:24.prints each column in your retina in a different location and the whole
:14:25. > :14:29.image is reassembled in the eye. Moving strips of super fast flashing
:14:30. > :14:34.LEDs are painting pictures or text in the air for a couple of decades,
:14:35. > :14:39.but this relies on our eyes to do the movement. Something they are
:14:40. > :14:47.naturally doing all the time. For what purpose? Well, enormous
:14:48. > :14:50.adverts, for a start. We've created a new type of projection technique
:14:51. > :14:55.for creating persistence of vision displays and we patted that globally
:14:56. > :15:00.and what that lets us do it is scale the display massively. -- patented.
:15:01. > :15:04.It becomes challenging the display anything more than three metres, but
:15:05. > :15:09.with our Eco technology we can create displays up to 200 metres
:15:10. > :15:14.tall, turning skyscrapers into the world's biggest image machines.
:15:15. > :15:19.That's why if you've been walking down a particular street in Berlin
:15:20. > :15:28.last Monday, you might have seen my face out of the corner of your eye.
:15:29. > :15:33.Do you think this is safe? Do you think this is to distract him for
:15:34. > :15:38.drivers, for example? It is very important that we introduce it in
:15:39. > :15:41.the right way. It isn't going to be for every location. I wouldn't want
:15:42. > :15:45.to introduce this next to a motorway. We need people to
:15:46. > :15:48.understand it and much like when LED billboards first came into the
:15:49. > :15:52.public realm, they were very distracting and there was
:15:53. > :15:57.legislation instantly put in place in all to prevent destruction from
:15:58. > :16:02.drivers. We are going to have to travel a similar path. That's not
:16:03. > :16:06.the only eye-catching projection that I've seen this week. The head
:16:07. > :16:10.of next week's Mobile world Congress in Barcelona have also managed to
:16:11. > :16:18.get a sneak preview of mobile devices. It is the latest version of
:16:19. > :16:24.Sony's XB projector, and android -based device that throws a touch
:16:25. > :16:28.sensitive display on a table or wall. It has all the top Seoul
:16:29. > :16:34.touchscreen functionality of a tablet, with your finger's decisions
:16:35. > :16:37.being watched by a camera under the projector and a row of infrared
:16:38. > :16:43.sensors at table level to detect when you've actually touched the
:16:44. > :16:47.surface. We are heading towards a world where our devices will be so
:16:48. > :16:51.small that we won't want a screen or a keyboard or any kind of device
:16:52. > :16:55.attached to them and I see this as one of the solutions. You just have
:16:56. > :17:04.a display when you want it on whatever surface is around. Very
:17:05. > :17:14.cool, but this week... Even that is not the coolest thing I've seen.
:17:15. > :17:20.From blue screen jungles to strange adventures in time, over the past
:17:21. > :17:24.few weeks we've been exploring some of the best visual effects from the
:17:25. > :17:32.past year and this week is no exception. Directed by Gareth
:17:33. > :17:38.Edwards, the visual genius behind Monsters and Godzilla, Rogue One has
:17:39. > :17:41.earned over $1 billion at the box office and has been nominated for an
:17:42. > :17:48.Oscar in visual effects. Edwards worked with the team at Industrial
:17:49. > :17:52.Lights and Magic to recreate that Galaxy and as we found out when we
:17:53. > :18:00.visited them in London they provided some very cool Kit to comment his
:18:01. > :18:03.unique directing style. He is a very hands-on filmmaker. Likes to walk
:18:04. > :18:09.around the sets and physically pick up the camera is and walk around and
:18:10. > :18:12.find interesting angles that might not have occurred to him when he was
:18:13. > :18:19.planning the shoots in preproduction. They were keen that
:18:20. > :18:23.they were able to apply that same style of film into the synthetic
:18:24. > :18:28.camera, so we used the real-time virtual reality system and so he
:18:29. > :18:37.could show us rather than explain it to us. This is it? This is what we
:18:38. > :18:41.call our V camera. It is an iPad with a controller stuck on the back!
:18:42. > :18:46.So you are using existing technology? Exactly. We can set it
:18:47. > :18:50.out relatively easily and quickly. Is this where he did the scenes?
:18:51. > :18:56.This is where he shot his virtual film. So this is the scene that was
:18:57. > :19:00.actually set up for the trailer, the first trailer. You have this thing
:19:01. > :19:10.running and he would just walk around and decide on his best angles
:19:11. > :19:15.and after that? The idea wasn't that he would be getting perfectly smooth
:19:16. > :19:20.camera moves, but he was able to sort of show to as the beginning of
:19:21. > :19:25.the shot, I want it here, the end of the shot, I wanted here. Then it
:19:26. > :19:31.could be immediately picked up eye animators. We shop this in London
:19:32. > :19:35.and then pushed it into the pipeline and it was picked up by people in
:19:36. > :19:41.San Francisco and take was ready for them to review the next morning.
:19:42. > :19:47.They I have a go? Absolutely. -- may I have. The animation in this scene
:19:48. > :19:53.is the dish of the death star. Look! You can see behind the dish! So I
:19:54. > :20:00.can get a different shot to Gareth if I wanted? If I find a better
:20:01. > :20:04.shot, do I get a job? Waiting for an answer.
:20:05. > :20:25.Look at that! It's the dish going to the death star. Here we are
:20:26. > :20:33.following it as it approaches the shield gate. We can move around and
:20:34. > :20:40.follow it in. Over to the front. This film is set in the minutes
:20:41. > :20:47.before the very first one and so getting these computer generators,
:20:48. > :20:50.the models, to look exactly like the physical models from 1977 was I
:20:51. > :20:58.guess vital? Our friends and colleagues in San Francisco took
:20:59. > :21:03.digital scans of the original models. They had lots of texture
:21:04. > :21:08.references and thankfully just recreated them so that there
:21:09. > :21:21.wouldn't be any jarring differences between these ships and the others.
:21:22. > :21:25.We have teams of people who are responsible for laying out camera
:21:26. > :21:32.moves, we have teams of people who are building digital models, texture
:21:33. > :21:36.and digital models. We have a fantastic team of animators and a
:21:37. > :21:41.team who take all of the range is that we generate and put it
:21:42. > :21:45.altogether with all the footage and integrate it into a photorealistic
:21:46. > :21:53.result. So this model here are, is that completely full detail, the UK
:21:54. > :21:57.move the cameras anywhere? We had a camera rotated around on its own and
:21:58. > :22:01.we moved it randomly around the city. We ended up with hundreds of
:22:02. > :22:07.views. So many of them were fascinating. Typically if you give a
:22:08. > :22:12.shot to layout you will start dressing everything to the camera.
:22:13. > :22:16.You will start laying out buildings, typically with lighting you will
:22:17. > :22:20.start with backlighting, from one direction. But what we found was
:22:21. > :22:24.that because none of those considerations had been taken, you
:22:25. > :22:28.end up with occasionally finding things that were so natural, so
:22:29. > :22:33.lighting would be eliminated on one half of the wall, in the background
:22:34. > :22:38.for example, or none of the roads are perpendicular to the camera.
:22:39. > :22:49.That was really successful and we ended up using a lot of those views
:22:50. > :22:59.as the background in our shoots. How much of that was based on a real
:23:00. > :23:03.mushroom cloud? A lot. We did spend a lot of time watching old footage
:23:04. > :23:04.of nuclear explosions. It is quite terrifying when you watch them over
:23:05. > :23:21.and over again. And we wish everyone who worked on
:23:22. > :23:25.Rogue One all of the best of luck for this weekend. Just a quick word
:23:26. > :23:30.about next week's programme, which will be at the Mobile World
:23:31. > :23:33.Congress, the big phone show in Barcelona. We will bring you the
:23:34. > :23:36.full view from the show, mainly because we will be repeating what we
:23:37. > :23:44.did in Switzerland last year and filming it in 360, although this
:23:45. > :23:47.time will be streaming some of it live and we will show you how we
:23:48. > :23:56.filmed this incredible super slow mode footage. -- slow motion. We
:23:57. > :24:01.will give you a clue, the device is very, very mobile! In fact, we will
:24:02. > :24:05.show you exactly what it is and how good it is online on Monday. Keep
:24:06. > :24:28.your eye on Twitter for more details!
:24:29. > :24:31.Well, Friday was much quieter and calmer day than what Thursday
