0:00:04 > 0:00:06This week, can this drone save a life?
0:00:06 > 0:00:11Can an app save your carpet?
0:00:11 > 0:00:21And will it be curtains for this flying lampshade?
0:00:39 > 0:00:42You could be forgiven for thinking that all this talk of drones
0:00:42 > 0:00:44has just been an excuse to make elaborate adverts
0:00:44 > 0:00:54for pizza deliveries!
0:00:54 > 0:00:55for pizza companies!
0:00:55 > 0:00:58Certainly though, if you believe the hype, it won't be long before
0:00:58 > 0:01:00drones are doing a lot more than just dropping off
0:01:00 > 0:01:01piping hot margaritas.
0:01:01 > 0:01:04Amazon's Prime Air, for example, promises to one day deliver
0:01:04 > 0:01:12packages to customers within 30 minutes or less.
0:01:12 > 0:01:15That's if they can make machines safe and convince government
0:01:15 > 0:01:16and regulators that is a good idea.
0:01:16 > 0:01:19Despite the promise, so far, drones have pretty much been
0:01:19 > 0:01:21constrained to wacky research project, and wacky racecourses.
0:01:21 > 0:01:27It feels to me that we are still waiting to see them come
0:01:27 > 0:01:29out of the labs and into the wild to
0:01:29 > 0:01:30make a real difference.
0:01:30 > 0:01:33So, where do you think we are going to go for
0:01:33 > 0:01:34this next drone story?
0:01:34 > 0:01:35Stanford, California?
0:01:35 > 0:01:36No, MIT, Boston?
0:01:36 > 0:01:45No, Dan Simmons is in Rwanda.
0:01:45 > 0:01:48This drone has beaten the biggest names in tech and retail to become
0:01:48 > 0:01:51the world's first to offer an ongoing commercial delivery
0:01:51 > 0:01:58service that works.
0:01:58 > 0:02:03I hung out with the guys in the run-up to the launch,
0:02:03 > 0:02:08and learnt some of the secrets of how they did it.
0:02:08 > 0:02:11First, assemble a crack squad.
0:02:11 > 0:02:14Don't let the West Coast looks fool you: these guys have
0:02:14 > 0:02:17engineered stuff for SpaceX, Lockheed Martin, Boeing and Google.
0:02:17 > 0:02:19They operate like the marines in freshers week.
0:02:19 > 0:02:23Yes, there will be mishaps, but they are focused.
0:02:23 > 0:02:26Second, don't use a chopper, quad copter or anything else that
0:02:26 > 0:02:29resembles a mobile blender.
0:02:29 > 0:02:35Fixed wing goes further, faster and is more of a bust.
0:02:35 > 0:02:37Right now we have a range of 150 kilometres, round-trip,
0:02:37 > 0:02:40it allows us to carry a bigger payload and it allows us to fly
0:02:40 > 0:02:44in all weather conditions.
0:02:44 > 0:02:46So we can fly in up to very high winds.
0:02:46 > 0:02:48And we can also fly in the rain.
0:02:48 > 0:02:55To get it off the ground, an elastic rubber cord is wound up
0:02:55 > 0:02:58and then catapults the drone, from zero to 80 kmph,
0:02:58 > 0:03:01in under one second.
0:03:01 > 0:03:06Once it's clear, two propellers click in, taking it up
0:03:06 > 0:03:10to a cruising speed of 100 kmph.
0:03:10 > 0:03:20Now, the pilot is the on-board computer.
0:03:21 > 0:03:23Following it is a very precise GPS called an RTK GTS.
0:03:23 > 0:03:27It gives us precision up to several centimetres, so every time a plane
0:03:27 > 0:03:30is going out for a mission, it gets a new set of ST cards
0:03:30 > 0:03:32with a new mission and then additionally, these ST cards become
0:03:32 > 0:03:35the black box of the vehicle, things like airspeed,
0:03:35 > 0:03:38ground speed, temperature of internal components,
0:03:38 > 0:03:43tracking errors, so if we are off a metre or two in one direction,
0:03:43 > 0:03:50all things we can feed back into the engineering crosses.
0:03:50 > 0:03:53all things we can feed back into the engineering process.
0:03:53 > 0:03:56If you are off one metre or two in one direction,
0:03:56 > 0:03:57is it that precise?
0:03:57 > 0:03:58Yes, that is our out about.
0:03:58 > 0:04:00This is a tennis ball.
0:04:00 > 0:04:02Have you got a fancy name for it?
0:04:02 > 0:04:05No.
0:04:05 > 0:04:11You called it a tennis ball.
0:04:11 > 0:04:14It is the preflight handle (!) Preflight handle impact buffer,
0:04:14 > 0:04:15we can call it that!
0:04:15 > 0:04:18Next trick, downland the thing to drop off the package,
0:04:18 > 0:04:19just dropped off the package.
0:04:19 > 0:04:21When over its target, these barn doors open
0:04:21 > 0:04:23and four rubber bands ping the cargo out of the hold,
0:04:23 > 0:04:25which hopefully has one of these attached.
0:04:25 > 0:04:31Next up, do lots of testing.
0:04:31 > 0:04:32Follow the plane...
0:04:32 > 0:04:40I will be behind the drop...
0:04:40 > 0:04:43LAUGHTER
0:04:43 > 0:04:50That was supposed to, that was supposed to drop dead then,
0:04:50 > 0:04:53That was supposed to, that was supposed to drop it then,
0:04:53 > 0:04:56as it went over, but something happened and it hasn't worked.
0:04:56 > 0:04:57So we might try another time.
0:04:57 > 0:05:00Zip dips to make the drop, but will not do so if it
0:05:00 > 0:05:01is of course.
0:05:01 > 0:05:02is off course.
0:05:02 > 0:05:06It will try ten times before it aborts the mission and goes home.
0:05:06 > 0:05:11This is the package that delivers, it comes down on what was not
0:05:11 > 0:05:13a brilliantly operational parachute, I guess, looks like it
0:05:13 > 0:05:15has come apart.
0:05:15 > 0:05:18This is biodegradable, one-time use.
0:05:18 > 0:05:21They don't need to worry about the environmental impact
0:05:21 > 0:05:25of using this.
0:05:25 > 0:05:27Inside is the life-saving package.
0:05:27 > 0:05:31This is the blood that will be used by surgeons,
0:05:31 > 0:05:34possibly to save somebody's life, and as you can see,
0:05:34 > 0:05:35it is extremely well wrapped up.
0:05:35 > 0:05:45I expect when we open it, it will be perfectly usable.
0:05:45 > 0:05:47You have a unique set of challenges in terms of blood
0:05:47 > 0:05:49and delivering other kinds of medical products,
0:05:49 > 0:05:51Rwanda is known as the land of a thousand hills,
0:05:51 > 0:05:53it can be a hard place to get around.
0:05:53 > 0:05:57We realised it was a place where we could move quickly and do
0:05:57 > 0:06:00something for the first time in the world, but also a place
0:06:00 > 0:06:02where the need was very high for something like Zip.
0:06:02 > 0:06:04While pizza delivery schemes may struggle to justify
0:06:04 > 0:06:07the cost of using drones, saving the lives of mothers
0:06:07 > 0:06:12after childbirth, or road accident victims, is something worth paying
0:06:12 > 0:06:20for.
0:06:51 > 0:06:52So you actually move the patient, sometimes,
0:06:52 > 0:06:55rather than actually get the blood to the patient, because it
0:06:55 > 0:06:56is quicker.
0:06:56 > 0:06:57Yes.
0:06:57 > 0:06:59Now, the doctor just need to send a text message.
0:06:59 > 0:07:02The government pays asked for each and every flight we do
0:07:02 > 0:07:05but the really cool thing is that these flights are actually
0:07:05 > 0:07:07about equal or a little less expensive than the way
0:07:07 > 0:07:08they were currently doing these deliveries,
0:07:09 > 0:07:09using motorcycles, or trucks.
0:07:09 > 0:07:12It's always useful to get yourself a friendly government
0:07:12 > 0:07:15that wants to help.
0:07:15 > 0:07:19Rwanda has form, it had fibre broadband ten years ago,
0:07:19 > 0:07:21was first in Africa to 4G, and the biggest investor
0:07:21 > 0:07:27in one laptop per child.
0:07:27 > 0:07:29This is innovation.
0:07:29 > 0:07:33We cannot figure out all of the right answers before we start.
0:07:33 > 0:07:35At the same time, we look at what is at stake,
0:07:35 > 0:07:39it is people's lives at stake.
0:07:39 > 0:07:41Why have you made different rules for this project?
0:07:41 > 0:07:44I don't think we have made rules for this project,
0:07:44 > 0:07:48we made rules for an industry.
0:07:48 > 0:07:54And what we are setting up for is really an environment
0:07:54 > 0:07:56which will allow many drones companies to come and
0:07:56 > 0:08:03operate on a commercial basis, even experiment.
0:08:03 > 0:08:06Zips fly below passenger plane airspace, and must
0:08:06 > 0:08:09report their position over the cell network, back to the nest and two
0:08:09 > 0:08:15air traffic control.
0:08:15 > 0:08:18back to the nest and to air traffic control.
0:08:18 > 0:08:20Nosing around alongside, international courier firm UPS.
0:08:20 > 0:08:21Might they use Zips?
0:08:21 > 0:08:24That first drone taking off today was actually a game changer.
0:08:24 > 0:08:27A game changer for the global logistics industry and a game
0:08:27 > 0:08:29changer for our humanitarian activities around the world.
0:08:29 > 0:08:33What happens if it hits a bird?
0:08:33 > 0:08:41We have never hit a bird, it is not super quiet,
0:08:41 > 0:08:43so birds hear it coming, and generally, a bird's life
0:08:43 > 0:08:46strategy is to stay away from birds that are bigger than it!
0:08:46 > 0:08:49So it is not a problem we have ever come in contact with.
0:08:49 > 0:08:53But, if we were to lose one motor, our vehicle is designed to be able
0:08:53 > 0:08:55to fly home on a single motor.
0:08:55 > 0:08:57And the final tip for drone delivery success, bring it home safely.
0:08:57 > 0:09:00Zipline plucks its drones from the sky, like they are landing
0:09:00 > 0:09:02on an aircraft carrier.
0:09:02 > 0:09:06The wire goes up, and the hook at the back of the zip catches...
0:09:06 > 0:09:09Bringing it down safely.
0:09:09 > 0:09:12Together with local residents, I looked on, and could not help
0:09:12 > 0:09:13but admire what this team has achieved,
0:09:13 > 0:09:17but I also had some concerns.
0:09:17 > 0:09:20The system relies on one team from the US, so expansion
0:09:20 > 0:09:22to an ever-increasing waiting list of African countries
0:09:22 > 0:09:27is likely to be slow.
0:09:27 > 0:09:30The drop needs an open but secure target area.
0:09:30 > 0:09:39This is not a to-the-door solution.
0:09:39 > 0:09:42We can have a plane ready to fly in less than five minutes.
0:09:42 > 0:09:45And given drones are more information for dropping munitions,
0:09:45 > 0:09:47seeing the military take an interest made me feel uneasy.
0:09:47 > 0:09:49Although the technology minister told me that is not the plan.
0:09:49 > 0:09:52What's happened here is a milestone, a commercially viable drone delivery
0:09:52 > 0:09:54service has been talked about for years, now finally,
0:09:54 > 0:10:04this crack squad have made the drop.
0:11:43 > 0:11:45Now, I can't compete with the life-saving drones
0:11:45 > 0:11:49in Rwanda, but I can show you a use for drones which may help to make
0:11:49 > 0:11:50them all a bit safer.
0:11:50 > 0:11:54And it looks spectacular, too.
0:11:54 > 0:11:58This is Cirque du Soleil's Broadway show, Paramour,
0:11:58 > 0:12:01the stars of that show are arguably not the performers but the flying
0:12:01 > 0:12:08lampshades.
0:12:08 > 0:12:11This is not just a one off film, remember, this is a live,
0:12:11 > 0:12:13repeatable performance.
0:12:13 > 0:12:15If you make a video, you have the luxury of
0:12:15 > 0:12:18If you make a video, you have the luxury of
0:12:18 > 0:12:20doing it a hundred times and choosing the best shot.
0:12:20 > 0:12:22If you are doing something on Broadway, it is running
0:12:22 > 0:12:24eight times a week, 2000 people each time.
0:12:24 > 0:12:26It needs to work every single time.
0:12:26 > 0:12:29So many things on a drone can fail, a battery could overheat,
0:12:29 > 0:12:31communication could be lost, and for those reasons,
0:12:31 > 0:12:33Paramour drones, seen here in their giant rehearsal space
0:12:33 > 0:12:35in Zurich, have built in redundancy, two batteries,
0:12:35 > 0:12:45two flight computers.
0:12:51 > 0:12:55But these quadcopters are even safer than that, they can still stay
0:12:55 > 0:12:58stable, and land safely, even if they use a propeller.
0:12:58 > 0:13:00Something that we will now demonstrate in a most
0:13:00 > 0:13:07spectacular and unnecessarily violent manner!
0:13:07 > 0:13:11LAUGHTER
0:13:11 > 0:13:16You didn't see me flinch, you were
0:13:16 > 0:13:20looking at the other thing, weren't you,
0:13:20 > 0:13:21see me run for cover!
0:13:21 > 0:13:26Do I need to tell you never to try this, ever?
0:13:26 > 0:13:28There is a fraction of a second, where I lose
0:13:28 > 0:13:36control of my bodily functions...
0:13:36 > 0:13:38Just a fraction.
0:13:38 > 0:13:43LAUGHTER
0:13:43 > 0:13:46When I said they can stay stable,
0:13:46 > 0:13:48I did mean after what I will call
0:13:48 > 0:13:49the initial evacuation...
0:13:49 > 0:13:51It's only because of the special control
0:13:51 > 0:13:53software developed here, that these drones can
0:13:53 > 0:13:54stay in control when a
0:13:54 > 0:13:55blade is stopped.
0:13:55 > 0:13:58The key ingredient to being able to fly on less than
0:13:58 > 0:13:59four propellers is spinning.
0:13:59 > 0:14:02So any flying machine that has had a failure and is now flying on less
0:14:02 > 0:14:04than four propellers will be spinning if
0:14:04 > 0:14:06it is trying to stay in one spot.
0:14:06 > 0:14:08No more gentle aerial photography, once you have lost a
0:14:08 > 0:14:10blade, but the thing can land safely.
0:14:10 > 0:14:12The most impressive thing about this recovery from disaster is
0:14:12 > 0:14:15that the drones need no special equipment to survive a lost prop.
0:14:15 > 0:14:16The capability of a quadcopter to
0:14:16 > 0:14:18fly on less than four propellers, is
0:14:18 > 0:14:23pure software feature.
0:14:23 > 0:14:25All standard quadcopters have all the sensors and actuators
0:14:25 > 0:14:30that they need for it.
0:14:30 > 0:14:33There is no good reason to have a drone that falls out of
0:14:33 > 0:14:35the sky just because one of the propellers has failed.
0:14:35 > 0:14:38the sky just because one of the propellers has failed.
0:14:38 > 0:14:40In fact, a drone can fly under control, albeit
0:14:40 > 0:14:42spinning, if it goes down to not just three
0:14:42 > 0:14:43blades but even down to two.
0:14:43 > 0:14:47So, could a drone fly on just one?
0:14:47 > 0:14:51Here's your answer.
0:14:51 > 0:14:52Nice.
0:14:52 > 0:14:56Oh, yeah.
0:14:56 > 0:14:58One propeller!
0:14:58 > 0:14:59One propeller.
0:14:59 > 0:15:01One propeller?!
0:15:01 > 0:15:03And no lifting surfaces, no other actuators, it is
0:15:03 > 0:15:08sustained aloft and controlling itself with only one propeller.
0:15:08 > 0:15:10This is really to push the boundary of
0:15:10 > 0:15:13what you can do with flying machines.
0:15:13 > 0:15:14The fact...
0:15:14 > 0:15:16We ask ourselves a simple question, what is
0:15:16 > 0:15:19the minimum number of actuators that you need to fly?
0:15:19 > 0:15:21We were surprised when the answer was one, we
0:15:21 > 0:15:24discovered this theoretically, and then we set out to build a
0:15:24 > 0:15:33prototype.
0:15:43 > 0:15:45Wow.
0:15:45 > 0:15:47Could a quad copter that we have today fly with one
0:15:47 > 0:15:50propeller, if it was using your algorithm?
0:15:50 > 0:15:51It could, if it was powerful enough.
0:15:51 > 0:15:53The limit then becomes, does one propeller have
0:15:53 > 0:15:55enough thrust to keep the quad copter aloft?
0:15:55 > 0:15:56You would never design...
0:15:56 > 0:15:59It would not be a good design if you designed a quad with
0:15:59 > 0:16:01five or six times excess thrust.
0:16:01 > 0:16:03It may not be practical, but that is what I like
0:16:03 > 0:16:06about what I have heard, he and his students
0:16:06 > 0:16:07in ETH in Zurich are
0:16:07 > 0:16:09learning huge amounts about balance and control systems, by pushing
0:16:09 > 0:16:12their machines beyond what we would normally want them to do.
0:16:12 > 0:16:14Balancing a stick on your head, or drone
0:16:14 > 0:16:16tennis, aren't probably top of the list, but this
0:16:16 > 0:16:18is all about reacting quickly to rapid changes,
0:16:18 > 0:16:20re-sampling the situation, re-calculating what to do, 50 times
0:16:20 > 0:16:24a second.
0:16:24 > 0:16:27And that leads to a drone that can recover from a massive
0:16:27 > 0:16:29shock, like a strong gust of wind, and impact,
0:16:29 > 0:16:31or, indeed, the loss of a propeller.
0:16:31 > 0:16:34I can also see uses for a drone that can fly like a
0:16:34 > 0:16:41plane or a helicopter.
0:16:41 > 0:16:43And one that can fly any way up.
0:16:43 > 0:16:45But, Raph is unashamedly theoretical.
0:16:45 > 0:16:47I look at it from what is possible.
0:16:47 > 0:16:48Whenever you push the boundary of what
0:16:48 > 0:16:58something can do, especially autonomous systems, then naturally,
0:17:04 > 0:17:11people see that and go, you could use this for that!
0:17:11 > 0:17:14I have seen that happen only a few times.
0:17:14 > 0:17:16You are the archetypal solution looking for a problem.
0:17:16 > 0:17:17Well...
0:17:17 > 0:17:19But I'm not looking for a problem, and
0:17:19 > 0:17:22the reason is, that, that serves a huge need in our society,
0:17:22 > 0:17:24to explore what is possible, to stimulate our
0:17:24 > 0:17:25imagination on what can be done.
0:17:25 > 0:17:28And what can be done is not just limited to drones.
0:17:28 > 0:17:29Sensors, gyroscopes and self balancing
0:17:29 > 0:17:31systems could be used to control nonflying objects, too.
0:17:31 > 0:17:34One day, a descendant of the QB here may be a
0:17:34 > 0:17:36robot, which balances and walks its way across
0:17:36 > 0:17:39the surface of another planet.
0:17:39 > 0:17:41As for the flying lampshades, they had better watch
0:17:41 > 0:17:45out, there is already something that wants to upstage them.
0:17:45 > 0:17:48Certainly a better circus act than this pair of
0:17:48 > 0:17:51chancers.
0:17:51 > 0:17:58BEEP
0:17:58 > 0:18:00Ah!
0:18:00 > 0:18:01First time!
0:18:01 > 0:18:11LAUGHTER.
0:18:13 > 0:18:16If you've ever felt that you've made a mistake when it comes to
0:18:16 > 0:18:20decorating or furnishing your home, then you are certainly not alone, so
0:18:20 > 0:18:29here are a few things that may be able to help in future.
0:18:29 > 0:18:31This app has it planned from the ground up,
0:18:31 > 0:18:41using augmented reality to change the appearance of your flooring.
0:18:44 > 0:18:46Through a combination of this Windows tablet and depth sensing
0:18:46 > 0:18:49camera, the app can interpret using its algorithm is exactly how far
0:18:49 > 0:18:51away the floor is and which area is floor.
0:18:51 > 0:18:53Retailers will be able to
0:18:53 > 0:18:56provide this setup as part of their service from later this year.
0:18:56 > 0:18:58I really like this function, you can change the direction of it.
0:18:58 > 0:19:02You can use this app, moving, and it will
0:19:02 > 0:19:04create the floor, in real-time, wherever
0:19:04 > 0:19:05you are moving to, so the
0:19:05 > 0:19:07carpet is disappearing and as I walk into the
0:19:07 > 0:19:11kitchen, it has changed the
0:19:11 > 0:19:15kitchen tiles, this does seem to be a room that the tiles make sense in.
0:19:15 > 0:19:18Not bad, now in some places, the images are a little bit
0:19:18 > 0:19:20fuzzy around the edges, that is all dependent on
0:19:21 > 0:19:25how good the light is in a room.
0:19:25 > 0:19:28The company's technology means there is
0:19:28 > 0:19:31no need to tell the app where the ground is and it is already
0:19:31 > 0:19:33being used by retailers to allow customers
0:19:33 > 0:19:43to virtually place furniture.
0:19:45 > 0:19:47AR being used to visualise items with a
0:19:47 > 0:19:50smartphone or tablet before buying them is nothing new, it is just
0:19:50 > 0:19:51improving.
0:19:51 > 0:19:54It has had over 2 million downloads, and will soon be
0:19:54 > 0:19:56available using Google Tango, the project we recently showed you on
0:19:56 > 0:19:59Click, where these functions will all be packed into an albeit chunky
0:19:59 > 0:20:00enabled smartphone.
0:20:00 > 0:20:04The depth sensing and motion tracking that the
0:20:04 > 0:20:07software and hardware in this device are capable of means you can really
0:20:07 > 0:20:10move around and see the furniture placed anywhere you want it to go,
0:20:10 > 0:20:17and You can also see the dimensions, which should be pretty
0:20:17 > 0:20:20and you can also see the dimensions, which should be pretty accurate.
0:20:20 > 0:20:23It is quite incredible actually, the level of detail, and
0:20:23 > 0:20:25the reflection that you get, which is not the real reflection
0:20:25 > 0:20:28but it is the impression of it being a reflection.
0:20:28 > 0:20:30Of course, measurements being precise is pretty pivotal, and
0:20:30 > 0:20:34that is where this smart tape measure can help.
0:20:34 > 0:20:38The Bagel, as it's known, which isn't for lunch, is
0:20:38 > 0:20:40currently in crowdfunding, and aims to measure any shape or size
0:20:40 > 0:20:43through its three different modes.
0:20:43 > 0:20:46String, Wheel or Remote, storing the data
0:20:46 > 0:20:49along with voice memos that you record on the go.
0:20:49 > 0:20:52Yet when it comes to the decor of the future,
0:20:52 > 0:21:01what it actually looks like could become less important.
0:21:01 > 0:21:03In the future, the technology will really help people
0:21:03 > 0:21:04to live the lives they want.
0:21:04 > 0:21:06They might not have very much money in
0:21:06 > 0:21:14the bank, and they can live in a horrible little shop, but with
0:21:14 > 0:21:17the bank, and they can live in a horrible little plot, but with
0:21:17 > 0:21:19augmented reality, and enhanced intelligence, they can have a
0:21:19 > 0:21:21fantastic palatial environment which looks exactly like where
0:21:21 > 0:21:22they would love to live.
0:21:22 > 0:21:25You might have one contact lens in each eye just looks
0:21:25 > 0:21:28like a normal contact lens, that could be producing an image straight
0:21:28 > 0:21:29onto your retina.
0:21:29 > 0:21:31The important thing though is that when it comes
0:21:31 > 0:21:34to the physical things, you still have do have a comfy seat.
0:21:34 > 0:21:37to the physical things, you still have to have a comfy seat.
0:21:37 > 0:21:39The comfy seat is the only thing that you
0:21:39 > 0:21:41actually have to have in your living room.
0:21:41 > 0:21:42When it comes to finding that
0:21:42 > 0:21:45comfortable seat, you may need to venture to an actual, real life
0:21:45 > 0:21:48furniture shop!
0:21:48 > 0:21:49Presuming they still exist(!)
0:21:49 > 0:21:51And finally, this.
0:21:51 > 0:21:55Meet holographic Thom Yorke.
0:21:55 > 0:21:57This ethereal visitor makes an appearance in Mark
0:21:57 > 0:22:04Pritchard's latest track, beautiful people.
0:22:04 > 0:22:05Pritchard's latest track, Beautiful People.
0:22:05 > 0:22:07Director Michal Marczak tells us what technology
0:22:07 > 0:22:09technology he's been using to create this haunting,
0:22:09 > 0:22:15rather alien vision.
0:22:15 > 0:22:19What I like about the track is that it was really melancholic.
0:22:19 > 0:22:20And evoked feelings of sadness.
0:22:20 > 0:22:21And loss.
0:22:21 > 0:22:22And loss.
0:22:22 > 0:22:23For me.
0:22:23 > 0:22:26But the vocals of Thom Yorke, they kind of exude
0:22:26 > 0:22:31a kind of sadness but
0:22:31 > 0:22:33at the same time something positive comes out of them.
0:22:33 > 0:22:34Like a sense of wonder.
0:22:34 > 0:22:36What could aliens in the future do to
0:22:36 > 0:22:37simulate a face?
0:22:37 > 0:22:40We thought it would be cool to have this utility
0:22:40 > 0:22:43fog.
0:22:43 > 0:22:46With thousands of one or two atom particles which can assemble into
0:22:46 > 0:22:48any form or shape, with a swarm intelligence.
0:22:48 > 0:22:50So we kind of thought that we would do these little
0:22:50 > 0:22:53metallic, hundreds of thousands of metallic particles, that can
0:22:53 > 0:23:00assemble into a face.
0:23:00 > 0:23:03We hacked a Kinect, that is what we used to
0:23:03 > 0:23:06scan Thom's face, it is infrared, not very precise, so we had
0:23:06 > 0:23:11to develop a technique to mellow it all out, it does not handle
0:23:11 > 0:23:21spikes, which are associated with the Kinect.
0:23:26 > 0:23:29And then to turn that into a strong mesh, which we can
0:23:29 > 0:23:36then simulate with particle simulation.
0:23:36 > 0:23:42To get it right, it was a couple of days of work.
0:23:42 > 0:23:45It is amazing that we have this type of technology and I
0:23:45 > 0:23:46can't wait until it is faster!
0:23:46 > 0:23:48I can't wait for that moment where you
0:23:48 > 0:23:52can have the camera, there, and augmented reality of what I am
0:23:52 > 0:23:54getting, and I'm really playing the visual effects of reality,
0:23:54 > 0:23:56and so this particle selection is reflecting
0:23:56 > 0:24:00off the light at this moment,
0:24:00 > 0:24:01we are adding so
0:24:01 > 0:24:03much realism to this thing.
0:24:03 > 0:24:07That is the amazing next step.
0:24:07 > 0:24:09And that is it for this week.
0:24:09 > 0:24:12You can follow us on Twitter throughout the week for loads
0:24:12 > 0:24:13of backstage photos and fun.
0:24:13 > 0:24:23Thank you very much for watching, see you soon.
