This week: waterfalls in Lyons, big screens, and the attack of the

:00:00.:00:22.

Australian box. We first meet Team Lab,

:00:23.:00:41.

the 400-strong digital art The team of artists programmers,

:00:42.:00:48.

engineers, CG animators, mathematicians and the like,

:00:49.:00:55.

love to make an impact and here at the Pace London gallery,

:00:56.:00:58.

they're presenting eight As with the work in Tokyo,

:00:59.:01:02.

the idea here combines motion censors and the projectors,

:01:03.:01:09.

which means you have a completely interactive piece that

:01:10.:01:12.

you can touch and change. The whole room has been fully

:01:13.:01:22.

calibrated so the censors can detect where everyone in the installation

:01:23.:01:26.

is really, really accurately. The artwork, the project,

:01:27.:01:31.

the projections, The pictures really do react

:01:32.:01:35.

to whatever you do while you're This room is called

:01:36.:01:44.

Flowers Bloom On People. With no-one in here,

:01:45.:02:00.

it's just a black room but if you sit around for a few

:02:01.:02:03.

minute, you'll find that nature Now I would say this is pretty

:02:04.:02:07.

cutting-edge projectector technology but Marc Cieslak has assured me

:02:08.:02:18.

he can give this a run This is a home entertainment concept

:02:19.:02:22.

from Razor, a company most famous for manufacturing gaming PCs,

:02:23.:02:33.

covering more lights than Blackpool The concept makes use of coloured

:02:34.:02:36.

lights and projected image, working together in

:02:37.:02:42.

synchronised harmony. What we have here is a concept

:02:43.:02:46.

lighting rig, which is key So the lights in this room

:02:47.:02:49.

will change colour depending on what's happening but it's only

:02:50.:02:54.

part of what's going on. So if I just hit this button here,

:02:55.:02:57.

we get the largest screen And that giant screen size is thanks

:02:58.:03:01.

to a pretty expensive The projector is fitted with a 155-

:03:02.:03:16.

degree fish eye lens, combined with two depth sensing

:03:17.:03:25.

cameras that scans the rooms for objects and furniture,

:03:26.:03:28.

and the system adjusts the image to prevent it from

:03:29.:03:32.

becoming distorting. So the idea is that by having

:03:33.:03:40.

a screen that envelopes, the peripheral vision of the viewer,

:03:41.:03:43.

you really feel like you're thrown inside the action,

:03:44.:03:46.

and it is surprisingly effective. At the moment, this system remains

:03:47.:03:49.

a concept but Razor has hinted it And now robots. One of the big users

:03:50.:04:16.

is to go to places and do work that is not safe for humans. But when

:04:17.:04:25.

Nick wanted to see the situation on a packed ice island in Australia, we

:04:26.:04:31.

completely believed him... But this is his story. Off the coast of

:04:32.:04:42.

Brisbane, Queensland, Serena and beauty. --A Serena beauty. But for

:04:43.:05:00.

over 60 years it was a prison. In 907, -- 19 seven, it was a colony

:05:01.:05:10.

fall leprosy. Hundreds from the mainland was sent here in ex- for a

:05:11.:05:16.

life sentence, with over half dying in isolation. Since closing in the

:05:17.:05:23.

late 50s, many of the unique buildings have fallen into

:05:24.:05:28.

disrepair. It has been tersely eaten by termites. The only thing keeping

:05:29.:05:37.

it up is the roof. The majority of the buildings are death trap, it too

:05:38.:05:43.

dangerous for people to enter. So this group of architectural and

:05:44.:05:51.

robotics expert are developing ways to preserve the building digitally.

:05:52.:05:57.

We are using a lot of different kind of equipment. -- clients. This six

:05:58.:06:11.

leg it best is designed to go into building is too dangerous for

:06:12.:06:17.

humans. With nimble limbs, it should trade -- transfers all sorts of the

:06:18.:06:29.

rain. It is a work in progress. The team are developing ways for it to

:06:30.:06:35.

feel the ground around it and detect for itself if the floor is safe

:06:36.:06:42.

enough to walk on. In the meantime, this has been built from the bottom

:06:43.:06:50.

up. It is all modular. We can we design as we go. We should be able

:06:51.:06:57.

to generate a real-time map as the robot drives through. Depending on

:06:58.:07:07.

what kind of image you want, for example if you have another system,

:07:08.:07:13.

depending on the conditions, you could add things. And, of course,

:07:14.:07:24.

they have a drone, equipped with her sense to scan the island from above.

:07:25.:07:31.

Covering is this a clearing in 14 minutes and that will have all of

:07:32.:07:35.

this area mapped from above to walk it and capture all the low staff.

:07:36.:07:41.

You're looking at half an hour, 40 minutes. Technology really allow us

:07:42.:07:49.

to capture the changing, fragile, remote and degrading site really

:07:50.:07:54.

quickly which is incredibly important because it is falling

:07:55.:07:59.

apart before our very eyes. It is an incredible example of inbuilt racism

:08:00.:08:06.

in architecture. This was the only example of segregation and it is

:08:07.:08:12.

important to understand the story and acknowledge it is part of our

:08:13.:08:15.

history. You cannot imagine sitting around here for 30 years, trapped on

:08:16.:08:26.

an island. Walking around here is really quite eerie to see how people

:08:27.:08:32.

were forced to live in these conditions against their will. You

:08:33.:08:36.

can see that inequality straightaway between how the whites lived and

:08:37.:08:44.

their purpose-built houses and nice patio and a lovely sea view and how

:08:45.:08:49.

everyone else, the nonwhites had to sleep. Sometimes four or five to

:08:50.:09:01.

just the shed. Galvanised iron. The government did not take too much

:09:02.:09:07.

notice of the aborigines. We need to look down into the ground and

:09:08.:09:13.

cemeteries for ground penetrating technology, because we do not know

:09:14.:09:19.

how many people are buried. We do not know who they are that it would

:09:20.:09:24.

be nice to note just how many and where they are also full of leaving

:09:25.:09:28.

the island I feel I have little of what it was like to live there. The

:09:29.:09:32.

team want to share that experience with others. They want to present

:09:33.:09:37.

their findings in virtual reality to educate new generation is about this

:09:38.:09:43.

part of Australia's past. The hope is that what they learn here will

:09:44.:09:52.

also help future technology and perhaps one day it could save lives.

:09:53.:10:04.

Hello and welcome to the week in Tech. Facebook announced its app to

:10:05.:10:13.

play videos on your TV. A new C five was born. And a newly opened it

:10:14.:10:21.

cybersecurity Centre, the idea slammed off using long complicated

:10:22.:10:25.

passwords. And talking of remembering numbers... Remember

:10:26.:10:33.

Nokia? Let them help you with the remake of an old model. Exclusive

:10:34.:10:40.

rights to the brand will launch in March. It is famed for great battery

:10:41.:10:50.

life, easy usage. Phones in Holland could be a step closer after the

:10:51.:10:59.

Dutch improve traffic lights. . Some would rather chance of death and

:11:00.:11:06.

look up. This time, more news for your hair. The unseen says this is

:11:07.:11:13.

the first air dye that changes colour depending on the temperature.

:11:14.:11:19.

Remarkably, that semi- permanent pigment is still looking for

:11:20.:11:27.

commercial partners. In Dubai, passenger journeys for this summer.

:11:28.:11:31.

This automatically flies to destinations depending on one person

:11:32.:11:37.

and depending on weight, their bag and swell. Now, we have often talked

:11:38.:11:45.

about virtual reality and self driving cars on the show but this

:11:46.:11:51.

week, we take a trip to see how some are put to impressive purposes.

:11:52.:11:55.

Oh, I can see lightings and stuff playing.

:11:56.:11:57.

I've been discovering some of the the latest ways

:11:58.:12:00.

that the technology is being used to help the visually impaired.

:12:01.:12:03.

It all starts with a spot of virtual reality.

:12:04.:12:06.

It just made me so, it was happiness but it made me cry and I just

:12:07.:12:19.

I'd been without full sight for so many years and then

:12:20.:12:26.

all of a sudden I could see things that I hadn't seen for 30 years.

:12:27.:12:34.

Here at the Beacon Centre, a charity supporting those

:12:35.:12:39.

with sight loss, an interesting trial is taking place.

:12:40.:12:42.

It seems some people can see things in VR they could never see

:12:43.:12:47.

Yes. Oh, no, he's there now!

:12:48.:12:59.

I'd never expected it but when they put the head set on,

:13:00.:13:05.

I mean there was giraffes, coming up and looking at me!

:13:06.:13:10.

What would you say to other people with a similar level of vision

:13:11.:13:14.

to you about the experience of being able to do this

:13:15.:13:17.

Oh, if you've got the chance, you have to have a go.

:13:18.:13:22.

I mean I know it's not full sight, because you've got to wear

:13:23.:13:28.

a machine, I'm not saying, that but to give you the experience,

:13:29.:13:31.

There are a wide range of conditions that cause sight loss.

:13:32.:13:42.

The nature of which can vary hugely, and even for those with similar

:13:43.:13:45.

problems, the benefits of the VR have varied.

:13:46.:13:50.

By along with the University of Wolverhampton, experts are trying

:13:51.:13:53.

to understand how this is possible at all.

:13:54.:13:57.

What we found quite quickly is that people who had central loss,

:13:58.:14:00.

macular type conditions, as they are called, are the ones

:14:01.:14:03.

Where they still had peripheral vision and whether that peripheral

:14:04.:14:08.

vision is so stimulated as to fill in the gaps,

:14:09.:14:10.

or, whatever wee don't understand yet, is it because it's so close?

:14:11.:14:14.

Is it because there are still sight receptive cells in the centre

:14:15.:14:18.

of the vision, so that when they're stimulated enough,

:14:19.:14:20.

that they will fire and therefore create the vision?

:14:21.:14:23.

There's a whole host of things we're still trying to explore

:14:24.:14:27.

If I could use that when my daughter's doing her school plays

:14:28.:14:37.

or she's singing in the choir, I could never pick out

:14:38.:14:40.

who she was or what she was doing, or be able to see what you are

:14:41.:14:44.

seeing and that could really be quite life changing.

:14:45.:14:50.

But however clear the virtual world may seem, finding ways to ease

:14:51.:14:53.

Temporary footway in road. Five to 10 metres.

:14:54.:15:03.

There are eye beacons built in here that connect this

:15:04.:15:09.

to the mobile app, so if somebody is approaching and they have the app

:15:10.:15:13.

installed in their phone, they will receive an alert to let

:15:14.:15:16.

them know about the roadworks and how best to approach them.

:15:17.:15:20.

And for someone like Louise with two young kids,

:15:21.:15:23.

this smart street furniture could make all the difference.

:15:24.:15:25.

Because it tells you which way to go, so it can still in my pocket

:15:26.:15:31.

I can have their hands, one in each, and I can hear the voiceover,

:15:32.:15:34.

so it will say something like the pedestrian crossing

:15:35.:15:37.

It's there for three days or however long.

:15:38.:15:42.

So if I do the school run the same day, I know exactly where it's

:15:43.:15:47.

going to be, I have done that walk yesterday.

:15:48.:15:49.

Also this week, big claims from a company that say their smart

:15:50.:15:52.

glasses can give the legally blind 20/20 vision.

:15:53.:15:56.

As well as being able to stream content, they've captured the user's

:15:57.:16:00.

surroundings, converting them into a form, they say,

:16:01.:16:02.

is easier to identify for those with limited vision.

:16:03.:16:05.

Sadly we couldn't put a pair to the test just yet,

:16:06.:16:11.

and it's early days for much of what is being trialled

:16:12.:16:14.

here but the possibilities are certainly looking good.

:16:15.:16:21.

Now, virtual reality has been grabbing all the headlines in recent

:16:22.:16:27.

years but don't forget augmented reality.

:16:28.:16:33.

Now, this is the idea of projecting computer generated images on top

:16:34.:16:37.

A bit like this but in a pair of glasses.

:16:38.:16:43.

Well, a small band of augmented reality pioneers have been really

:16:44.:16:46.

Here's Marc again with some pretty classy eyewear.

:16:47.:16:54.

These augmented reality glasses are basically a wearable computer.

:16:55.:16:58.

For the last couple of years, augmented reality specs have been

:16:59.:17:01.

used primarily in an industrial setting or in the workplace.

:17:02.:17:05.

These have been competed by a company called ODG,

:17:06.:17:08.

and they've been designed far more with the consumer in mind.

:17:09.:17:14.

They feel a lot closer to normal glasses, so to get the best out

:17:15.:17:18.

So, I stand up, at the moment, there's a 360-degree video playing.

:17:19.:17:27.

If I look around, I get a different viewpoint here.

:17:28.:17:32.

I see a robot in front of me and what looks like some kind

:17:33.:17:35.

of futuristic hospital, and there's a guy over here,

:17:36.:17:39.

who seems very unhappy and another guy who looks seems to be

:17:40.:17:42.

The images move seemlessly with my head.

:17:43.:17:47.

If I look around I can see planet Earth in front of me.

:17:48.:17:50.

I can walk inside it and see from outside of the planet,

:17:51.:17:56.

and appreciate it from this angle, and if I stand here,

:17:57.:17:59.

yep, a Space Station that's orbiting the earth as well.

:18:00.:18:07.

Now, the glasses know where they are, spacially,

:18:08.:18:14.

because there's a couple of cameras on front of them.

:18:15.:18:17.

And all of the processing is happening on the head set itself.

:18:18.:18:20.

The ODGR-8 glasses will cost around ?800 but they are basically

:18:21.:18:23.

There are some cheaper lower tech AR options

:18:24.:18:33.

There are lots of low-cost virtual reality headsets that make

:18:34.:18:37.

This is a low-cost augmented reality headset that uses a phone.

:18:38.:18:42.

Put an AR app on it and the images on the screen

:18:43.:18:49.

So when the headset's on, I can look down the screen

:18:50.:19:02.

and I scan see graphics reflected from the phone just in the headset.

:19:03.:19:06.

Now, it has another trick up its sleeve as well.

:19:07.:19:08.

I can see my hands in front of me and use them to cast flames.

:19:09.:19:14.

Just a normal day at the office for Marc then. Now, if you're watching

:19:15.:19:25.

the programme last week you would have seen us chatting with the

:19:26.:19:29.

visual effects supervisor for the film the jungle book. Last Sunday

:19:30.:19:33.

the team behind it picked up one of the biggest honours in the film

:19:34.:19:37.

world and won the BAFTA for Best visual effects. Many congratulations

:19:38.:19:42.

to them and of course we'll claim absolutely no credit for their

:19:43.:19:46.

victory. See, we love visual effects! Can't you tell? This week

:19:47.:19:57.

we're continuing the buildup to buildup to the Academy Awards by

:19:58.:20:00.

looking at another movie that's been nominated in the Best visual effects

:20:01.:20:03.

category, this time it's Marvel's Doctor strange. Now, we got

:20:04.:20:06.

exclusive access to industrial like magic in London, they worked on the

:20:07.:20:10.

breathtaking final scene in the film set in Hong Kong. Warning, if you

:20:11.:20:13.

haven't seen the movie yet, this next set contains spoilers. I

:20:14.:20:17.

repeat, it contains spoilers. Still with us? Good. I spent so many years

:20:18.:20:29.

peering through time. Looking for you. The idea of reversing the

:20:30.:20:35.

traditional end to any kind of superhero movie where it gets bigger

:20:36.:20:39.

and bigger and the city gets destroyed and the superhero saves

:20:40.:20:43.

the day, but there's a big old destruction going on. This is the

:20:44.:20:46.

opposite, there's a big old destruction going on and it gets

:20:47.:20:51.

reversed, by the end the city is pristine, nobody knows they hero

:20:52.:20:54.

saves the day because he made time go backwards. One of the challenges

:20:55.:20:59.

was constantly selling backwards time, every shot is stuffed with

:21:00.:21:08.

things falling upwards, explosions happening, puddles splashing, people

:21:09.:21:11.

not falling over and these things so we mixed together some footage of

:21:12.:21:14.

people going forwards in time, that's one of the things in the

:21:15.:21:18.

movie, Doctor Strange and his friend are going forward in time but they

:21:19.:21:21.

exist in an environment going back in time. Mixing those two things

:21:22.:21:24.

together is quite challenging. There are some digital humans in there but

:21:25.:21:28.

there's also a lot of play photography as well so one of the

:21:29.:21:32.

big challenges was how do you have convincing footage of people moving

:21:33.:21:35.

forwards and backwards but with the camera moving? One of the solutions

:21:36.:21:38.

was using something called motion control, a computer-controlled

:21:39.:21:43.

camera so we could film Benedict Cumberbatch as Doctor Strange and

:21:44.:21:46.

the camera moving around, record the move and reversed the same move and

:21:47.:21:50.

have the extras running through the frame. When you reversed the

:21:51.:21:55.

footage, the camera move goes back to the original movement but

:21:56.:21:58.

everyone in the frame by virtue of reversing the footage is running

:21:59.:22:02.

backwards. Now you're mixing together people running forwards and

:22:03.:22:05.

people running backwards in the same footage. But once you get beyond

:22:06.:22:09.

that, of course, every frame is full of explosions and fire and smoke so

:22:10.:22:13.

the key thing again is blending those things together and making

:22:14.:22:16.

sure people aren't running through places where there's meant to be an

:22:17.:22:19.

explosion or Doctor Strange hasn't got someone running through his cape

:22:20.:22:30.

because lots of careful planning has to go into making sure there's no

:22:31.:22:33.

interceptions of the action so that can be achieved by having markers on

:22:34.:22:37.

the floor, saying Doctor Strange will be here, people do forget those

:22:38.:22:40.

things, though, and people run straight through. Or it can be a

:22:41.:22:44.

case of doing something called body tracking, so we might look at Doctor

:22:45.:22:48.

Strange, we might point out his arm or shoulder is here in 3-D space by

:22:49.:22:51.

measuring the distance on a computer and having something bounce off his

:22:52.:22:55.

shoulder, so it sells he's in the played by emphasising the

:22:56.:22:58.

physicality of the area so we can put in some 3-D generated degree so

:22:59.:23:02.

it can bounce off him and go in a different ways of there's a variety

:23:03.:23:05.

of ways you can approach these things together. This is a breakdown

:23:06.:23:10.

of one of the shots we did, it gives you an idea of some of the layers of

:23:11.:23:14.

material that go into something like this. That's the plate photography,

:23:15.:23:17.

this was all shot at longshot studios, a set built along the

:23:18.:23:20.

bottom and the top of everything is digital and all the flying debris is

:23:21.:23:26.

digital. You can see there's a mixture of actors running forwards

:23:27.:23:29.

and Doctor Strange in there as well, a shot of different plates are mixed

:23:30.:23:43.

together. So much you don't know. Teach me!

:23:44.:23:50.

Yet, Benedict Cumberbatch giving Doctor Who a run for his money in

:23:51.:23:56.

the tiny whiny nurse of it all. That's it from us, this is at the

:23:57.:24:01.

gallery until the end of March and you can see a few more photos from

:24:02.:24:07.

this and all the other things on Twitter and @BBCclick is where we

:24:08.:24:11.

live. Thanks for watching and see you soon.

:24:12.:24:37.

No great dramas expected weatherwise through this weekend.

:24:38.:24:39.

Certainly no cold weather in prospect.

:24:40.:24:40.

A relatively mild weekend coming up and a lot of dry weather too.

:24:41.:24:45.
