:00:00. > :00:22.This week: waterfalls in Lyons, big screens, and the attack of the
:00:23. > :00:41.Australian box. We first meet Team Lab,
:00:42. > :00:48.the 400-strong digital art The team of artists programmers,
:00:49. > :00:55.engineers, CG animators, mathematicians and the like,
:00:56. > :00:58.love to make an impact and here at the Pace London gallery,
:00:59. > :01:02.they're presenting eight As with the work in Tokyo,
:01:03. > :01:09.the idea here combines motion censors and the projectors,
:01:10. > :01:12.which means you have a completely interactive piece that
:01:13. > :01:22.you can touch and change. The whole room has been fully
:01:23. > :01:26.calibrated so the censors can detect where everyone in the installation
:01:27. > :01:31.is really, really accurately. The artwork, the project,
:01:32. > :01:35.the projections, The pictures really do react
:01:36. > :01:44.to whatever you do while you're This room is called
:01:45. > :02:00.Flowers Bloom On People. With no-one in here,
:02:01. > :02:03.it's just a black room but if you sit around for a few
:02:04. > :02:07.minute, you'll find that nature Now I would say this is pretty
:02:08. > :02:18.cutting-edge projectector technology but Marc Cieslak has assured me
:02:19. > :02:22.he can give this a run This is a home entertainment concept
:02:23. > :02:33.from Razor, a company most famous for manufacturing gaming PCs,
:02:34. > :02:36.covering more lights than Blackpool The concept makes use of coloured
:02:37. > :02:42.lights and projected image, working together in
:02:43. > :02:46.synchronised harmony. What we have here is a concept
:02:47. > :02:49.lighting rig, which is key So the lights in this room
:02:50. > :02:54.will change colour depending on what's happening but it's only
:02:55. > :02:57.part of what's going on. So if I just hit this button here,
:02:58. > :03:01.we get the largest screen And that giant screen size is thanks
:03:02. > :03:16.to a pretty expensive The projector is fitted with a 155-
:03:17. > :03:25.degree fish eye lens, combined with two depth sensing
:03:26. > :03:28.cameras that scans the rooms for objects and furniture,
:03:29. > :03:32.and the system adjusts the image to prevent it from
:03:33. > :03:40.becoming distorting. So the idea is that by having
:03:41. > :03:43.a screen that envelopes, the peripheral vision of the viewer,
:03:44. > :03:46.you really feel like you're thrown inside the action,
:03:47. > :03:49.and it is surprisingly effective. At the moment, this system remains
:03:50. > :04:16.a concept but Razor has hinted it And now robots. One of the big users
:04:17. > :04:25.is to go to places and do work that is not safe for humans. But when
:04:26. > :04:31.Nick wanted to see the situation on a packed ice island in Australia, we
:04:32. > :04:42.completely believed him... But this is his story. Off the coast of
:04:43. > :05:00.Brisbane, Queensland, Serena and beauty. --A Serena beauty. But for
:05:01. > :05:10.over 60 years it was a prison. In 907, -- 19 seven, it was a colony
:05:11. > :05:16.fall leprosy. Hundreds from the mainland was sent here in ex- for a
:05:17. > :05:23.life sentence, with over half dying in isolation. Since closing in the
:05:24. > :05:28.late 50s, many of the unique buildings have fallen into
:05:29. > :05:37.disrepair. It has been tersely eaten by termites. The only thing keeping
:05:38. > :05:43.it up is the roof. The majority of the buildings are death trap, it too
:05:44. > :05:51.dangerous for people to enter. So this group of architectural and
:05:52. > :05:57.robotics expert are developing ways to preserve the building digitally.
:05:58. > :06:11.We are using a lot of different kind of equipment. -- clients. This six
:06:12. > :06:17.leg it best is designed to go into building is too dangerous for
:06:18. > :06:29.humans. With nimble limbs, it should trade -- transfers all sorts of the
:06:30. > :06:35.rain. It is a work in progress. The team are developing ways for it to
:06:36. > :06:42.feel the ground around it and detect for itself if the floor is safe
:06:43. > :06:50.enough to walk on. In the meantime, this has been built from the bottom
:06:51. > :06:57.up. It is all modular. We can we design as we go. We should be able
:06:58. > :07:07.to generate a real-time map as the robot drives through. Depending on
:07:08. > :07:13.what kind of image you want, for example if you have another system,
:07:14. > :07:24.depending on the conditions, you could add things. And, of course,
:07:25. > :07:31.they have a drone, equipped with her sense to scan the island from above.
:07:32. > :07:35.Covering is this a clearing in 14 minutes and that will have all of
:07:36. > :07:41.this area mapped from above to walk it and capture all the low staff.
:07:42. > :07:49.You're looking at half an hour, 40 minutes. Technology really allow us
:07:50. > :07:54.to capture the changing, fragile, remote and degrading site really
:07:55. > :07:59.quickly which is incredibly important because it is falling
:08:00. > :08:06.apart before our very eyes. It is an incredible example of inbuilt racism
:08:07. > :08:12.in architecture. This was the only example of segregation and it is
:08:13. > :08:15.important to understand the story and acknowledge it is part of our
:08:16. > :08:26.history. You cannot imagine sitting around here for 30 years, trapped on
:08:27. > :08:32.an island. Walking around here is really quite eerie to see how people
:08:33. > :08:36.were forced to live in these conditions against their will. You
:08:37. > :08:44.can see that inequality straightaway between how the whites lived and
:08:45. > :08:49.their purpose-built houses and nice patio and a lovely sea view and how
:08:50. > :09:01.everyone else, the nonwhites had to sleep. Sometimes four or five to
:09:02. > :09:07.just the shed. Galvanised iron. The government did not take too much
:09:08. > :09:13.notice of the aborigines. We need to look down into the ground and
:09:14. > :09:19.cemeteries for ground penetrating technology, because we do not know
:09:20. > :09:24.how many people are buried. We do not know who they are that it would
:09:25. > :09:28.be nice to note just how many and where they are also full of leaving
:09:29. > :09:32.the island I feel I have little of what it was like to live there. The
:09:33. > :09:37.team want to share that experience with others. They want to present
:09:38. > :09:43.their findings in virtual reality to educate new generation is about this
:09:44. > :09:52.part of Australia's past. The hope is that what they learn here will
:09:53. > :10:04.also help future technology and perhaps one day it could save lives.
:10:05. > :10:13.Hello and welcome to the week in Tech. Facebook announced its app to
:10:14. > :10:21.play videos on your TV. A new C five was born. And a newly opened it
:10:22. > :10:25.cybersecurity Centre, the idea slammed off using long complicated
:10:26. > :10:33.passwords. And talking of remembering numbers... Remember
:10:34. > :10:40.Nokia? Let them help you with the remake of an old model. Exclusive
:10:41. > :10:50.rights to the brand will launch in March. It is famed for great battery
:10:51. > :10:59.life, easy usage. Phones in Holland could be a step closer after the
:11:00. > :11:06.Dutch improve traffic lights. . Some would rather chance of death and
:11:07. > :11:13.look up. This time, more news for your hair. The unseen says this is
:11:14. > :11:19.the first air dye that changes colour depending on the temperature.
:11:20. > :11:27.Remarkably, that semi- permanent pigment is still looking for
:11:28. > :11:31.commercial partners. In Dubai, passenger journeys for this summer.
:11:32. > :11:37.This automatically flies to destinations depending on one person
:11:38. > :11:45.and depending on weight, their bag and swell. Now, we have often talked
:11:46. > :11:51.about virtual reality and self driving cars on the show but this
:11:52. > :11:55.week, we take a trip to see how some are put to impressive purposes.
:11:56. > :11:57.Oh, I can see lightings and stuff playing.
:11:58. > :12:00.I've been discovering some of the the latest ways
:12:01. > :12:03.that the technology is being used to help the visually impaired.
:12:04. > :12:06.It all starts with a spot of virtual reality.
:12:07. > :12:19.It just made me so, it was happiness but it made me cry and I just
:12:20. > :12:26.I'd been without full sight for so many years and then
:12:27. > :12:34.all of a sudden I could see things that I hadn't seen for 30 years.
:12:35. > :12:39.Here at the Beacon Centre, a charity supporting those
:12:40. > :12:42.with sight loss, an interesting trial is taking place.
:12:43. > :12:47.It seems some people can see things in VR they could never see
:12:48. > :12:59.Yes. Oh, no, he's there now!
:13:00. > :13:05.I'd never expected it but when they put the head set on,
:13:06. > :13:10.I mean there was giraffes, coming up and looking at me!
:13:11. > :13:14.What would you say to other people with a similar level of vision
:13:15. > :13:17.to you about the experience of being able to do this
:13:18. > :13:22.Oh, if you've got the chance, you have to have a go.
:13:23. > :13:28.I mean I know it's not full sight, because you've got to wear
:13:29. > :13:31.a machine, I'm not saying, that but to give you the experience,
:13:32. > :13:42.There are a wide range of conditions that cause sight loss.
:13:43. > :13:45.The nature of which can vary hugely, and even for those with similar
:13:46. > :13:50.problems, the benefits of the VR have varied.
:13:51. > :13:53.By along with the University of Wolverhampton, experts are trying
:13:54. > :13:57.to understand how this is possible at all.
:13:58. > :14:00.What we found quite quickly is that people who had central loss,
:14:01. > :14:03.macular type conditions, as they are called, are the ones
:14:04. > :14:08.Where they still had peripheral vision and whether that peripheral
:14:09. > :14:10.vision is so stimulated as to fill in the gaps,
:14:11. > :14:14.or, whatever wee don't understand yet, is it because it's so close?
:14:15. > :14:18.Is it because there are still sight receptive cells in the centre
:14:19. > :14:20.of the vision, so that when they're stimulated enough,
:14:21. > :14:23.that they will fire and therefore create the vision?
:14:24. > :14:27.There's a whole host of things we're still trying to explore
:14:28. > :14:37.If I could use that when my daughter's doing her school plays
:14:38. > :14:40.or she's singing in the choir, I could never pick out
:14:41. > :14:44.who she was or what she was doing, or be able to see what you are
:14:45. > :14:50.seeing and that could really be quite life changing.
:14:51. > :14:53.But however clear the virtual world may seem, finding ways to ease
:14:54. > :15:03.Temporary footway in road. Five to 10 metres.
:15:04. > :15:09.There are eye beacons built in here that connect this
:15:10. > :15:13.to the mobile app, so if somebody is approaching and they have the app
:15:14. > :15:16.installed in their phone, they will receive an alert to let
:15:17. > :15:20.them know about the roadworks and how best to approach them.
:15:21. > :15:23.And for someone like Louise with two young kids,
:15:24. > :15:25.this smart street furniture could make all the difference.
:15:26. > :15:31.Because it tells you which way to go, so it can still in my pocket
:15:32. > :15:34.I can have their hands, one in each, and I can hear the voiceover,
:15:35. > :15:37.so it will say something like the pedestrian crossing
:15:38. > :15:42.It's there for three days or however long.
:15:43. > :15:47.So if I do the school run the same day, I know exactly where it's
:15:48. > :15:49.going to be, I have done that walk yesterday.
:15:50. > :15:52.Also this week, big claims from a company that say their smart
:15:53. > :15:56.glasses can give the legally blind 20/20 vision.
:15:57. > :16:00.As well as being able to stream content, they've captured the user's
:16:01. > :16:02.surroundings, converting them into a form, they say,
:16:03. > :16:05.is easier to identify for those with limited vision.
:16:06. > :16:11.Sadly we couldn't put a pair to the test just yet,
:16:12. > :16:14.and it's early days for much of what is being trialled
:16:15. > :16:21.here but the possibilities are certainly looking good.
:16:22. > :16:27.Now, virtual reality has been grabbing all the headlines in recent
:16:28. > :16:33.years but don't forget augmented reality.
:16:34. > :16:37.Now, this is the idea of projecting computer generated images on top
:16:38. > :16:43.A bit like this but in a pair of glasses.
:16:44. > :16:46.Well, a small band of augmented reality pioneers have been really
:16:47. > :16:54.Here's Marc again with some pretty classy eyewear.
:16:55. > :16:58.These augmented reality glasses are basically a wearable computer.
:16:59. > :17:01.For the last couple of years, augmented reality specs have been
:17:02. > :17:05.used primarily in an industrial setting or in the workplace.
:17:06. > :17:08.These have been competed by a company called ODG,
:17:09. > :17:14.and they've been designed far more with the consumer in mind.
:17:15. > :17:18.They feel a lot closer to normal glasses, so to get the best out
:17:19. > :17:27.So, I stand up, at the moment, there's a 360-degree video playing.
:17:28. > :17:32.If I look around, I get a different viewpoint here.
:17:33. > :17:35.I see a robot in front of me and what looks like some kind
:17:36. > :17:39.of futuristic hospital, and there's a guy over here,
:17:40. > :17:42.who seems very unhappy and another guy who looks seems to be
:17:43. > :17:47.The images move seemlessly with my head.
:17:48. > :17:50.If I look around I can see planet Earth in front of me.
:17:51. > :17:56.I can walk inside it and see from outside of the planet,
:17:57. > :17:59.and appreciate it from this angle, and if I stand here,
:18:00. > :18:07.yep, a Space Station that's orbiting the earth as well.
:18:08. > :18:14.Now, the glasses know where they are, spacially,
:18:15. > :18:17.because there's a couple of cameras on front of them.
:18:18. > :18:20.And all of the processing is happening on the head set itself.
:18:21. > :18:23.The ODGR-8 glasses will cost around ?800 but they are basically
:18:24. > :18:33.There are some cheaper lower tech AR options
:18:34. > :18:37.There are lots of low-cost virtual reality headsets that make
:18:38. > :18:42.This is a low-cost augmented reality headset that uses a phone.
:18:43. > :18:49.Put an AR app on it and the images on the screen
:18:50. > :19:02.So when the headset's on, I can look down the screen
:19:03. > :19:06.and I scan see graphics reflected from the phone just in the headset.
:19:07. > :19:08.Now, it has another trick up its sleeve as well.
:19:09. > :19:14.I can see my hands in front of me and use them to cast flames.
:19:15. > :19:25.Just a normal day at the office for Marc then. Now, if you're watching
:19:26. > :19:29.the programme last week you would have seen us chatting with the
:19:30. > :19:33.visual effects supervisor for the film the jungle book. Last Sunday
:19:34. > :19:37.the team behind it picked up one of the biggest honours in the film
:19:38. > :19:42.world and won the BAFTA for Best visual effects. Many congratulations
:19:43. > :19:46.to them and of course we'll claim absolutely no credit for their
:19:47. > :19:57.victory. See, we love visual effects! Can't you tell? This week
:19:58. > :20:00.we're continuing the buildup to buildup to the Academy Awards by
:20:01. > :20:03.looking at another movie that's been nominated in the Best visual effects
:20:04. > :20:06.category, this time it's Marvel's Doctor strange. Now, we got
:20:07. > :20:10.exclusive access to industrial like magic in London, they worked on the
:20:11. > :20:13.breathtaking final scene in the film set in Hong Kong. Warning, if you
:20:14. > :20:17.haven't seen the movie yet, this next set contains spoilers. I
:20:18. > :20:29.repeat, it contains spoilers. Still with us? Good. I spent so many years
:20:30. > :20:35.peering through time. Looking for you. The idea of reversing the
:20:36. > :20:39.traditional end to any kind of superhero movie where it gets bigger
:20:40. > :20:43.and bigger and the city gets destroyed and the superhero saves
:20:44. > :20:46.the day, but there's a big old destruction going on. This is the
:20:47. > :20:51.opposite, there's a big old destruction going on and it gets
:20:52. > :20:54.reversed, by the end the city is pristine, nobody knows they hero
:20:55. > :20:59.saves the day because he made time go backwards. One of the challenges
:21:00. > :21:08.was constantly selling backwards time, every shot is stuffed with
:21:09. > :21:11.things falling upwards, explosions happening, puddles splashing, people
:21:12. > :21:14.not falling over and these things so we mixed together some footage of
:21:15. > :21:18.people going forwards in time, that's one of the things in the
:21:19. > :21:21.movie, Doctor Strange and his friend are going forward in time but they
:21:22. > :21:24.exist in an environment going back in time. Mixing those two things
:21:25. > :21:28.together is quite challenging. There are some digital humans in there but
:21:29. > :21:32.there's also a lot of play photography as well so one of the
:21:33. > :21:35.big challenges was how do you have convincing footage of people moving
:21:36. > :21:38.forwards and backwards but with the camera moving? One of the solutions
:21:39. > :21:43.was using something called motion control, a computer-controlled
:21:44. > :21:46.camera so we could film Benedict Cumberbatch as Doctor Strange and
:21:47. > :21:50.the camera moving around, record the move and reversed the same move and
:21:51. > :21:55.have the extras running through the frame. When you reversed the
:21:56. > :21:58.footage, the camera move goes back to the original movement but
:21:59. > :22:02.everyone in the frame by virtue of reversing the footage is running
:22:03. > :22:05.backwards. Now you're mixing together people running forwards and
:22:06. > :22:09.people running backwards in the same footage. But once you get beyond
:22:10. > :22:13.that, of course, every frame is full of explosions and fire and smoke so
:22:14. > :22:16.the key thing again is blending those things together and making
:22:17. > :22:19.sure people aren't running through places where there's meant to be an
:22:20. > :22:30.explosion or Doctor Strange hasn't got someone running through his cape
:22:31. > :22:33.because lots of careful planning has to go into making sure there's no
:22:34. > :22:37.interceptions of the action so that can be achieved by having markers on
:22:38. > :22:40.the floor, saying Doctor Strange will be here, people do forget those
:22:41. > :22:44.things, though, and people run straight through. Or it can be a
:22:45. > :22:48.case of doing something called body tracking, so we might look at Doctor
:22:49. > :22:51.Strange, we might point out his arm or shoulder is here in 3-D space by
:22:52. > :22:55.measuring the distance on a computer and having something bounce off his
:22:56. > :22:58.shoulder, so it sells he's in the played by emphasising the
:22:59. > :23:02.physicality of the area so we can put in some 3-D generated degree so
:23:03. > :23:05.it can bounce off him and go in a different ways of there's a variety
:23:06. > :23:10.of ways you can approach these things together. This is a breakdown
:23:11. > :23:14.of one of the shots we did, it gives you an idea of some of the layers of
:23:15. > :23:17.material that go into something like this. That's the plate photography,
:23:18. > :23:20.this was all shot at longshot studios, a set built along the
:23:21. > :23:26.bottom and the top of everything is digital and all the flying debris is
:23:27. > :23:29.digital. You can see there's a mixture of actors running forwards
:23:30. > :23:43.and Doctor Strange in there as well, a shot of different plates are mixed
:23:44. > :23:50.together. So much you don't know. Teach me!
:23:51. > :23:56.Yet, Benedict Cumberbatch giving Doctor Who a run for his money in
:23:57. > :24:01.the tiny whiny nurse of it all. That's it from us, this is at the
:24:02. > :24:07.gallery until the end of March and you can see a few more photos from
:24:08. > :24:11.this and all the other things on Twitter and @BBCclick is where we
:24:12. > :24:37.live. Thanks for watching and see you soon.
:24:38. > :24:39.No great dramas expected weatherwise through this weekend.
:24:40. > :24:40.Certainly no cold weather in prospect.
:24:41. > :24:45.A relatively mild weekend coming up and a lot of dry weather too.
