Whereat the extremists hiding? Without realising it, they have

:00:09.:00:12.

already told the world. Technology touches every aspect of

:00:13.:00:39.

our lives, and it is usually used for good. Sometimes, it is used for

:00:40.:00:43.

good. Sometimes, it is useful ill as well. That seems to be the case with

:00:44.:00:49.

the news coming out of Syria and Iraq which has been unremittingly

:00:50.:00:52.

grim. Islamic State has been waging a campaign of terror with horrific

:00:53.:00:55.

results. One particularly new aspect of this has been the extensive and

:00:56.:00:58.

expert use of social media to broadcast its message, both to

:00:59.:01:01.

create fear and to bring in new recruits. Some Twitter users this

:01:02.:01:07.

week started urging others to stop sharing the material under the

:01:08.:01:19.

#ISISblackout. We have come to Leicester to meet one person who is

:01:20.:01:22.

using his skills to turn their own propaganda against them. This is

:01:23.:01:25.

Elliot Higgins, father of one and resident of Leicester and a

:01:26.:01:27.

self`employed investigative journalist. Working from a small

:01:28.:01:31.

office, he is the founder of Belling Cat, a website which uses open

:01:32.:01:34.

source databases and power of the crowd to analyse photos and videos

:01:35.:01:37.

posted by insurgents in Syria and Iraq and tries to work out where

:01:38.:01:51.

they were taken. For example, spotting details and bridges,

:01:52.:01:53.

unusual buildings and other notable features in the background of these

:01:54.:01:56.

propaganda shots of a training camp somewhere in Iraq, he was able to

:01:57.:01:59.

match the photos to similar shots taken by locals and two satellite

:02:00.:02:02.

images, to pinpoint the location of the camp. Earlier this year, after

:02:03.:02:14.

the Flight MH17 crash in Ukraine, he monitored photos on Instagram and

:02:15.:02:17.

Twitter by people in the area to track the journey of an unusual

:02:18.:02:20.

military vehicle that he thinks was carrying a surface`to`air missile on

:02:21.:02:25.

that day. He believes that he has been able to pinpoint the field from

:02:26.:02:31.

which it was launched. This is from a video in the Ukraine. There is

:02:32.:02:35.

that white spot and this is one from Russia. It is the same one. It might

:02:36.:02:41.

look small but this operation costs money. Elliott gave up his job to do

:02:42.:02:45.

this full`time and has raised ?50,000 through Kickstarter to

:02:46.:02:51.

sustain and expand his operation. Well, it really started when looked

:02:52.:02:54.

I was looking at the conflict in Libya. Really, I was just interested

:02:55.:03:03.

in current events. There was information being posted on sites

:03:04.:03:05.

like Youtube and Twitter and Facebook which was being ignored. It

:03:06.:03:08.

seemed to be that some of this information was interesting. The

:03:09.:03:11.

problem was the question of how do we know if it is true. I started to

:03:12.:03:15.

teach myself ways to verify the information. One of the first videos

:03:16.:03:18.

I looked at had a big main road and a mosque in it. They said that it

:03:19.:03:22.

this certain town and I went to the town and I found the road and I

:03:23.:03:26.

found exactly the same mosque and I could verify it was the same town

:03:27.:03:29.

using that information. While you may have assume that government

:03:30.:03:32.

agencies are already doing this kind of stuff and with better resources

:03:33.:03:35.

than one laptop, Elliott does not think that they are. Yeah, I've been

:03:36.:03:38.

contacted by all kinds of different agencies, you know, different

:03:39.:03:41.

departments of the same agency, saying, "This is interesting, how do

:03:42.:03:44.

you do it? " It is something I'm very willing to show them. It is

:03:45.:03:50.

open source information. If I can figure out where someone was

:03:51.:03:53.

standing when they were filming the video and they do it every week,

:03:54.:03:56.

then that means that people with artillery and rocket launchers can

:03:57.:03:59.

also target that position. Last week, he claims to have pinpointed a

:04:00.:04:02.

location in Syria where the American journalist James Foley was killed by

:04:03.:04:09.

militants. You can make out ` it is most likely to be trees rather than

:04:10.:04:26.

individual structures. This is a best estimate based on what we know.

:04:27.:04:30.

I am certain that it is in this region. Motorist in the UK are being

:04:31.:04:46.

warned of the danger of using these devices while driving. The US space

:04:47.:05:18.

agency have been debating whether to send more devices into space. The US

:05:19.:05:24.

space agency NASA has announced which companies it is backing to

:05:25.:05:27.

take the country's astronauts back into space. Since retiring their own

:05:28.:05:30.

shuttles in 2011, the Americans have had to rely on Russian ships to get

:05:31.:05:33.

off the ground. The decision sees $6.2 billion being paid out to

:05:34.:05:36.

Boeing and SpaceX in order to develop their human spaceflight

:05:37.:05:39.

capability. If all goes to plan, NASA will have rockets by the end of

:05:40.:05:42.

2017. Panasonic has unveiled a hybrid smartphone camera with a huge

:05:43.:05:45.

one inch, 20 megapixel sensor, more normally found in its dedicated

:05:46.:05:48.

camera.s Unveiled at a trade show in Cologne, the extra optical heft

:05:49.:05:51.

should improve sensitivity in low light and allow the phone it to

:05:52.:05:53.

shoot ultra`high`definition video. Large lens phone cameras seem to be

:05:54.:05:57.

something of a trend at the moment. It is a programmer in`joke that has

:05:58.:06:00.

become a surprise gaming hit. Goat Simulator is trotting off PC and

:06:01.:06:03.

going to Android and iOS devices. It is a third`person or third`goat

:06:04.:06:06.

adventure which allows people to take their goat to the fair or ride

:06:07.:06:09.

a bike. It has intentionally buggy sections and rubbish controls.

:06:10.:06:12.

Now, if you own a home cinema system, the chances are that you

:06:13.:06:15.

have not been to the actual cinema in quite a while. One way that movie

:06:16.:06:18.

theatres are trying to lure audiences back is with 3`D which

:06:19.:06:22.

seems to work better in a controlled space than in a home environment.

:06:23.:06:25.

The problem is that 3`D is not as realistic or as comfortable to watch

:06:26.:06:29.

as perhaps it could be. Now, the movie industry is looking to

:06:30.:06:32.

introduce a new breed of 3`D. We sent Dan Simmons to Amsterdam to

:06:33.:06:35.

witness the first screening of a film made with the new technology.

:06:36.:06:45.

The number of cinema``goers choosing the 3`D version of a film has

:06:46.:06:49.

dropped by a third in the last four years. People are falling out of

:06:50.:07:00.

love with 3`D. The novelty has worn off. They are not bright enough.

:07:01.:07:04.

They are too dim. You can only hear the movie. You know how your mother

:07:05.:07:07.

said, "Don't read in the dark"? It is not going to be a comfortable

:07:08.:07:11.

experience. Now that we can show it at this proper light level, it is a

:07:12.:07:15.

shot in the arm for the format. This is the world's first screening of a

:07:16.:07:18.

full`length movies using the 6P system. We project two images

:07:19.:07:20.

simultaneously for the left and right eyes. The whole idea is we do

:07:21.:07:24.

not have to flash between the two. It is a better and more persistent

:07:25.:07:27.

vision. Therefore, the 3`D looks more natural. We don't go through

:07:28.:07:30.

life alternating our eyes. We go through life with both eyes open and

:07:31.:07:34.

we see both offset images at the same time. These are not servers.

:07:35.:07:42.

They are laser power units, pumping out up to 100,000 beams of light

:07:43.:07:51.

down fibre`optic to two projectors. Basically put, each projector uses a

:07:52.:07:53.

different mix of colours of wavelengths to send the same picture

:07:54.:08:01.

to each eye. Using these classes, they only allow certain wavelengths

:08:02.:08:05.

of light through. The left eye can only see what is coming out of our

:08:06.:08:09.

projector, the right, what is coming out of this. The important thing is

:08:10.:08:13.

that it has not been possible in the past to get the whole project worth

:08:14.:08:17.

of light into each eye at the same time. Now we can and that replicates

:08:18.:08:25.

how we see. We are using a system called colour separation based 3`D

:08:26.:08:28.

which is different from 99% of cinemas which use polarisation

:08:29.:08:32.

schemes. That system needs something in front of the projector or inside

:08:33.:08:36.

the projector to polarise the light. That absorbs a lot of light. With a

:08:37.:08:40.

spectral separation or a colour`separation based technique,

:08:41.:08:42.

using lasers, we can generate the light right from the source at the

:08:43.:08:48.

correct wavelength. We eliminate the filter stage. The only thing between

:08:49.:08:52.

you and the image or you and the projector are the glasses. Finally,

:08:53.:09:02.

we have a technology solution to make 3D as bright as 2`D. The new

:09:03.:09:07.

system is bright enough to do away with the traditional silver screen,

:09:08.:09:10.

which can create hotspots of brightness, depending on where we

:09:11.:09:15.

st. The nice part about having a flat map screen is that it basically

:09:16.:09:19.

looks the same across the board for people sitting on the front row, the

:09:20.:09:25.

side row or the back row. That at least allows everybody to see the

:09:26.:09:28.

movie the way the filmmaker wanted them to when he made it. This is

:09:29.:09:38.

certainly one of the best 3D experiences I've had. I have to say,

:09:39.:09:41.

the glasses are not just reflected on this site but this side as well,

:09:42.:09:46.

so you do get a little bit of reflection when you look through the

:09:47.:09:49.

lenses but it is crisp and clear and the colours are brilliant. Could it

:09:50.:09:59.

be the saviour of 3D film? I think it's a fundamental piece to continue

:10:00.:10:00.

to support that format. ROAR. It turns out that we are celebrating

:10:01.:10:31.

something, because this is click episode number 750. The BBC has

:10:32.:10:35.

finally decided to give us our own YouTube channel. Yes, I know, we

:10:36.:10:41.

have been asking for it for quite a few years, and if I am honest I

:10:42.:10:46.

think they came to the decision relatively quickly. Anyway, we have

:10:47.:10:51.

dusted off our original YouTube trailer, and I think it still works.

:10:52.:11:00.

This radio controlled helicopter can not only fly itself, but it can also

:11:01.:11:07.

being video imagery straight onto the information superhighway. It is

:11:08.:11:13.

the smart phone skirt tailored from 80 smartphones. Electrically powered

:11:14.:11:23.

unicycle for perambulation. It beams that information based on my

:11:24.:11:25.

location, allowing me to record whatever I want. It can enhance

:11:26.:11:36.

reality with extra information. Click. Tomorrow's world, today.

:11:37.:11:46.

Anyway, you can subscribe to the channel at YouTube .com/BBC click.

:11:47.:11:55.

Enjoy that, thank you very much for watching. We will see you next time.
