0:00:01 > 0:00:03That's it from me.
0:00:03 > 0:00:04Duncan Golestani's here at 2 o'clock.
0:00:05 > 0:00:07Now on BBC News, it's time to Click.
0:00:07 > 0:00:08This week...
0:00:08 > 0:00:17Unexpected item in the bagging area.
0:00:18 > 0:00:19Giving VR a good kicking.
0:00:19 > 0:00:20And, going up?
0:00:20 > 0:00:24Err, sideways.
0:00:42 > 0:00:48This month marks the 25th anniversary of the self checkout.
0:00:48 > 0:00:51The first one was installed in New York on August five,
0:00:51 > 0:00:591992, Amy Price Chopper.
0:00:59 > 0:01:001992, in Price Chopper.
0:01:00 > 0:01:02So, what does its inventor, Doctor Howard Schneider,
0:01:02 > 0:01:03remember of it all?
0:01:03 > 0:01:06I hadn't gone shopping much, so I went to the supermarket
0:01:07 > 0:01:10near my house with a stopwatch, and I started looking at people
0:01:10 > 0:01:12checking out, and my stopwatch went "Click, click" -
0:01:12 > 0:01:14it was a mechanical one.
0:01:14 > 0:01:16And, you know, I said well, what a great environment.
0:01:16 > 0:01:17This is so messy.
0:01:18 > 0:01:19Good luck with any machine doing it...
0:01:19 > 0:01:22And I said, this would be a great problem to solve.
0:01:22 > 0:01:25And then I started building a machine in my garage.
0:01:25 > 0:01:28I actually spent every cent I had on parts and I got
0:01:28 > 0:01:30the first machines built.
0:01:30 > 0:01:33See, I love self-service checkouts, but then I'm a control freak,
0:01:33 > 0:01:36but I do believe they save you time.
0:01:36 > 0:01:39Until they go wrong, at which point they become a right
0:01:39 > 0:01:41pain in the bagging area.
0:01:41 > 0:01:45The technology in the machines now is less than it was 25 years ago,
0:01:45 > 0:01:50using 286 computers, using MS-DOS, 3.3...
0:01:50 > 0:01:54I had better technology 25 years ago then what you see now.
0:01:54 > 0:01:56Which is the reason for a lot of frustration.
0:01:56 > 0:01:58Please wait for assistance.
0:01:59 > 0:02:01Unexpected item in the bagging area.
0:02:01 > 0:02:04Please remove item before continuing.
0:02:04 > 0:02:07So now people are thinking outside of the shopping basket to try
0:02:07 > 0:02:11and update the self checkout and reduce the delays further.
0:02:11 > 0:02:18In Japan, Reggie Robo takes your basket and bags you're
0:02:18 > 0:02:20-- your shopping for you.
0:02:20 > 0:02:23The system, which was trialled at the beginning of the year,
0:02:23 > 0:02:26scans that RFID tags on all of the items at the same time.
0:02:27 > 0:02:29Since December, the Amazon Go shop has been undergoing
0:02:29 > 0:02:30testing in Seattle.
0:02:30 > 0:02:33Once it is working, shoppers should be able to pick up their items
0:02:33 > 0:02:35and simply walk out of the store.
0:02:35 > 0:02:40Swedish cafe company, Wheelys, is working on a similar idea.
0:02:40 > 0:02:48Although this staff must shop will even come to you...
0:02:48 > 0:02:51Although this staff-less shop will even come to you...
0:02:51 > 0:02:53Here at Canary Wharf in London, something less spectacular but,
0:02:53 > 0:02:56which seems to me, more workable and more scalable.
0:02:56 > 0:02:58Grab and Go has been invented by Barclaycard.
0:02:58 > 0:03:01The apps scans bar codes as you grab items off-the-shelf,
0:03:01 > 0:03:04and then you just go!
0:03:04 > 0:03:08Payment is taken from the card that is linked to the app,
0:03:08 > 0:03:11and the receipt is sent to the phone, so you don't have
0:03:11 > 0:03:14to wait in a checkout queue at all.
0:03:14 > 0:03:16But, with all that grabbing and going, are you thinking
0:03:16 > 0:03:22what I'm thinking?
0:03:22 > 0:03:25In the future, if you're scanning things and putting it in your bag,
0:03:25 > 0:03:28and then just walking out, and all the doors are open...
0:03:28 > 0:03:32I can see more people stealing more stuff.
0:03:33 > 0:03:36So you can basically very easily pick up some item and then walk out,
0:03:36 > 0:03:40but the way you have CCTV, you have a man on the ground
0:03:40 > 0:03:41basically monitoring all of that.
0:03:41 > 0:03:43It works in exactly the same way.
0:03:43 > 0:03:46So it's no more secure than a self scan checkout,
0:03:46 > 0:03:49but I do wonder how many people would just "accidentally miss" that
0:03:49 > 0:03:52bar code, and leave with a lot of unpaid staff...
0:03:52 > 0:03:54Although, even here, technology might be able
0:03:54 > 0:03:55to spot them.
0:03:55 > 0:03:58Supermarket giant Walmart has filed a patent to incorporate facial
0:03:58 > 0:04:00recognition, blood pressure and heart rate monitoring
0:04:00 > 0:04:02into its stores to try and understand customer
0:04:02 > 0:04:05frustration at checkouts.
0:04:05 > 0:04:09It might improve customer service, but previous trials of the tech have
0:04:09 > 0:04:12been used to try to spot shoplifters, raising a fuse security
0:04:12 > 0:04:17concerns along the way.
0:04:17 > 0:04:20In fact, only this week, the supermarket announced it is also
0:04:20 > 0:04:23trialling a scan and go solution, but this one relies on shop
0:04:23 > 0:04:28assistant approval before you can leave.
0:04:29 > 0:04:33In China, home to several unmanned stores like this one,
0:04:33 > 0:04:37you need your face to get in the front door in the first place.
0:04:37 > 0:04:40Like Barclaycard's Grab and Go, customers scan items
0:04:40 > 0:04:43using their phones and they can even heat up their grub
0:04:43 > 0:04:45in the microwave inside.
0:04:45 > 0:04:48Speaking of heating things up, a similar Chinese idea,
0:04:48 > 0:04:53Bingo Box, ran into problems when one of its glass clad stores
0:04:53 > 0:04:56began to overheat.
0:04:56 > 0:04:59As it was unmanned, it wasn't until customers began to complain
0:04:59 > 0:05:01that the sweltering temperatures were ruining the food
0:05:01 > 0:05:04inside that the shop was shut down.
0:05:04 > 0:05:09It is now back up and running, and everything is cool...
0:05:09 > 0:05:12So, it's not all plain sailing for these souped up shops,
0:05:12 > 0:05:16and it will be a while before we buy our weekly groceries in store
0:05:16 > 0:05:19without some form of human interaction, or intervention.
0:05:19 > 0:05:22But, as our patience wears increasingly thin in this age
0:05:22 > 0:05:25of grabbing and going, it's no surprise that Bingo Box
0:05:25 > 0:05:33plans to open 5000 more stores in the coming year.
0:05:38 > 0:05:41Premier League football starts again this weekend,
0:05:41 > 0:05:45which I'm reliably informed is important to some people.
0:05:45 > 0:05:47Seriously, though, fans will be excited to see what their club's
0:05:47 > 0:05:51new signings have to offer.
0:05:51 > 0:05:55But, how do you know if a new player is going to be right for your team?
0:05:55 > 0:05:59Well, one company is using virtual reality to identify talent and also
0:05:59 > 0:06:01help players to recover from injuries.
0:06:01 > 0:06:05Here is Carol Hawkins.
0:06:09 > 0:06:12I'm in Manchester, home of great football, to check out a small
0:06:12 > 0:06:14start-up that is joining up with Premier League clubs
0:06:14 > 0:06:18for an idea that's only eight months in the making.
0:06:18 > 0:06:21I feel like I'm doing pretty good!
0:06:22 > 0:06:25This VR system helps scouts recruit players by using statistics
0:06:25 > 0:06:29from virtual gameplay to decide whether or not the player would work
0:06:29 > 0:06:32for a team.
0:06:32 > 0:06:35But separately it is being used to help injured players get back
0:06:35 > 0:06:36to full fitness.
0:06:36 > 0:06:38Mentally and physically.
0:06:38 > 0:06:41You have injured players who will often spend anything
0:06:41 > 0:06:44from six months to ten months, years out of the game.
0:06:44 > 0:06:48And the scientists, the physios will work with them,
0:06:48 > 0:06:52but we do not know what they are going to do in a situation,
0:06:52 > 0:06:54what decisions they are going to make.
0:06:54 > 0:06:57Now, they can play games, as well as having the treatment,
0:06:57 > 0:07:02the movement is limited but they can feel part of the squad.
0:07:02 > 0:07:05They are using an HTC5 headset, with the usual hand controllers
0:07:05 > 0:07:06attached to shin pads.
0:07:06 > 0:07:09The kit is wireless, crucial for football drills.
0:07:09 > 0:07:12As well as this vision, they are also working on one
0:07:12 > 0:07:16for goalies, which will require an extra pair of sensors.
0:07:16 > 0:07:20Several Premier League clubs are signing up to use the VR system
0:07:20 > 0:07:24as it promises to bring players back from the bench faster.
0:07:24 > 0:07:28The first question they ask - does it feel like a real ball?
0:07:30 > 0:07:33You do feel like you are really hitting the ball,
0:07:33 > 0:07:36it is quite strange.
0:07:36 > 0:07:41I don't know if it is the sound, or the visuals, but it is very
0:07:41 > 0:07:44immersive, and I know people always use that word for VR,
0:07:45 > 0:07:48but it does feel as though you are hitting it...
0:07:48 > 0:07:51But, of course you are not.
0:07:51 > 0:07:54And because you are not, it's important players don't try too
0:07:54 > 0:07:57hard and injure themselves even more, especially when they have cost
0:07:57 > 0:08:00clubs millions of pounds.
0:08:00 > 0:08:03We had an injured player last week who is not allowed to kick
0:08:03 > 0:08:04a physical ball.
0:08:04 > 0:08:07He's fit, he could probably run a marathon, but the injury means
0:08:07 > 0:08:09he cannot do it.
0:08:09 > 0:08:13He got in this and it was basically a case of, I feel like I am
0:08:14 > 0:08:14kicking a ball.
0:08:14 > 0:08:16Psychologically, it is massive.
0:08:16 > 0:08:20I am now in the rehab drill and there is a man to my left
0:08:20 > 0:08:24who is tracing a S with his foot.
0:08:24 > 0:08:27Now, I cannot do that, because my balance on these
0:08:27 > 0:08:29prosthetics just is not there, sorry, physios!
0:08:29 > 0:08:34But I can see how that would be very useful for injured players,
0:08:34 > 0:08:38but not just injured players, in hospitals.
0:08:38 > 0:08:40Players will complete a set of exercises and drills
0:08:40 > 0:08:43which will be scored, and their fitness can then be
0:08:43 > 0:08:45judged by coaches.
0:08:45 > 0:08:47Elsewhere in the sport world, American football
0:08:47 > 0:08:49is embracing VR quickly.
0:08:49 > 0:08:52STRIVR there is a company out of Stanford University,
0:08:52 > 0:08:55currently working with seven NFL teams to allow players to practice
0:08:55 > 0:09:00any time, anywhere, without the same physical tolls.
0:09:00 > 0:09:02And in the Netherlands, another VR company, Beyond Sports,
0:09:03 > 0:09:06has a contract with both Arsenal and Stoke City for match analysis
0:09:06 > 0:09:09and VR training.
0:09:09 > 0:09:16But back in the UK, a man who won Premier League titles as a player
0:09:16 > 0:09:18and coach with Manchester United thinks the new technology
0:09:18 > 0:09:20could really help.
0:09:20 > 0:09:23I think it benefits both amateur, professional and grassroots.
0:09:23 > 0:09:28You can put pressure into this situation.
0:09:29 > 0:09:30The technology is part of sport now.
0:09:30 > 0:09:33Football, possibly, have had a reluctance to use it,
0:09:33 > 0:09:35but it is moving in that direction.
0:09:35 > 0:09:38But the kit being offered is not cheap.
0:09:39 > 0:09:41With packages starting at ?5,000 and increasing to more
0:09:41 > 0:09:45than ?20,000 a month.
0:09:45 > 0:09:49But the potential benefits of VR to the football clubs that can
0:09:49 > 0:09:54afford it are intriguing, coaches want to train and test
0:09:54 > 0:09:57footballers in the most effective way by recreating the pressure
0:09:57 > 0:10:00and intensity of performing in a packed stadium.
0:10:00 > 0:10:03So, what would the manager with the most Premier League titles
0:10:03 > 0:10:06under his belt, Sir Alex Ferguson, think about it?
0:10:06 > 0:10:09He would have a look at it, yeah.
0:10:09 > 0:10:11I think he would.
0:10:11 > 0:10:14He was open to all that sort of stuff.
0:10:15 > 0:10:18As long as it made a bit of a difference, or sometimes
0:10:18 > 0:10:21it is what people like, you know, players like it.
0:10:21 > 0:10:23They like something new and fresh.
0:10:23 > 0:10:26Top clubs are big businesses, and the money in football is only
0:10:27 > 0:10:27going to increase.
0:10:27 > 0:10:31And, as it does, teams will be looking for any way to improve.
0:10:31 > 0:10:36As you watch your team this weekend, remember that last-minute win
0:10:36 > 0:10:40or fingertip save might be the result of some hard hours spent
0:10:40 > 0:10:44in a virtual world...
0:10:48 > 0:10:51Hello, and welcome to the Week in Tech.
0:10:51 > 0:10:55It was the week that the US military announced it might shoot down
0:10:55 > 0:11:00civilian drones if they fly in a American bases.
0:11:00 > 0:11:03civilian drones if they fly near American bases.
0:11:03 > 0:11:05And, the telephone numbers and e-mail addresses
0:11:05 > 0:11:08of Game Of Thrones stars were leaked by hackers demanding a ransom
0:11:08 > 0:11:09from TV network HBO.
0:11:09 > 0:11:12FaceApp has pulled a new feature labelled as "Racist",
0:11:12 > 0:11:15which allowed users to edit selfies into Caucasian,
0:11:15 > 0:11:18Asian, Indian, or black.
0:11:18 > 0:11:23And social networking behemoth Facebook is taking on TV and YouTube
0:11:23 > 0:11:26by revamping its video offering.
0:11:26 > 0:11:29Labelled "Watch", it would feature specially commissioned shows,
0:11:29 > 0:11:32as well as cat videos and clips of people falling over.
0:11:32 > 0:11:35And Disney is going to pull its content from Netflix,
0:11:35 > 0:11:39after the House of Mouse announced that in 2019 it's launching a rival
0:11:39 > 0:11:41video streaming service, dedicated to family friendly
0:11:41 > 0:11:44Disney fare.
0:11:44 > 0:11:46Don't you worry, pal.
0:11:46 > 0:11:49You had a good run!
0:11:49 > 0:11:51There's no word yet whether the service will show any
0:11:51 > 0:11:57Marvel or Lucas Film content - like Star Wars, which did
0:11:57 > 0:11:59Marvel or Lucas Film content - like Star Wars, which
0:11:59 > 0:12:00Disney also owns.
0:12:00 > 0:12:03And finally, the man who made passwords a massive pain now says
0:12:03 > 0:12:06much of what I did, I now regret.
0:12:06 > 0:12:08Bill Burr created the US National Institute of Standards
0:12:08 > 0:12:10and Technology's guidelines, including things like changing your
0:12:10 > 0:12:12password every three months and using complicated character
0:12:12 > 0:12:13combinations.
0:12:13 > 0:12:16He now thinks this is a waste of time, as people still pick
0:12:16 > 0:12:18rubbish passwords which hackers can break.
0:12:18 > 0:12:25They are just harder for us to actually remember.
0:12:33 > 0:12:36Weather, particularly in Britain, can be changeable
0:12:36 > 0:12:41at the best of times.
0:12:41 > 0:12:44For all the dramatic change to come over the next 24 hours,
0:12:44 > 0:12:47I should know, having spent a decade as a weather presenter before
0:12:47 > 0:12:50joining Click, it's not just about knowing the forecast,
0:12:50 > 0:12:54you also need to be prepared whatever the weather.
0:12:54 > 0:12:58And, if you are not that organised, luckily I found a couple of devices
0:12:58 > 0:13:01that should be able to help...
0:13:02 > 0:13:07Sunflower, open.
0:13:07 > 0:13:11This prototype autonomous sunshade can be voice controlled,
0:13:11 > 0:13:16or use artificial intelligence to know what to do, when.
0:13:16 > 0:13:19OK, the main function here is probably pretty obvious,
0:13:19 > 0:13:23and that is to protect you from the sun.
0:13:23 > 0:13:27This device aims to be a little bit more clever than that.
0:13:27 > 0:13:30As the sun moves throughout the day, the top of the umbrella
0:13:30 > 0:13:31will also move.
0:13:31 > 0:13:34The panels on it will be harvesting solar power and also making sure
0:13:34 > 0:13:39that you get maximum protection wherever the sun is.
0:13:39 > 0:13:41So some of the other functions in here?
0:13:41 > 0:13:44Well, there is a camera and a microphone providing security
0:13:44 > 0:13:45when you are out.
0:13:45 > 0:13:49There's also the ability to be able to play music I ask it now,
0:13:49 > 0:13:52through voice recognition I should be able to do that.
0:13:52 > 0:13:53Sunflower, play classical.
0:13:53 > 0:13:59CLASSICAL MUSIC PLAYS.
0:13:59 > 0:14:02By launch later this year, it is expected to be able to fully
0:14:02 > 0:14:05connected to the smart home, as well as virtual assistants
0:14:05 > 0:14:07Amazon Eco or Google Home.
0:14:07 > 0:14:12All very well - if a price tag of up to ?3000 does not bother you...
0:14:12 > 0:14:19Sorry, hang on, I just need to charge my phone...
0:14:19 > 0:14:21And for those moments the sun isn't shining,
0:14:21 > 0:14:26well, you wouldn't want your washing getting wet, would you?
0:14:26 > 0:14:33So, how about a smart clothes peg?
0:14:33 > 0:14:37Peggy is still at prototype stage, but the finished product aims to be
0:14:37 > 0:14:39able to track ultra localised weather using these sensors
0:14:39 > 0:14:42within the device, as well as pulling data from online
0:14:42 > 0:14:44forecasts so you know whether you should be
0:14:44 > 0:14:49putting your washing out or not.
0:14:49 > 0:14:53Handy, if it works.
0:14:53 > 0:14:56But for keeping yourself dry, well, a few smart umbrellas,
0:14:56 > 0:15:04in all shapes and sizes, have emerged in the last few years.
0:15:04 > 0:15:06As much as this umbrella may look difficult to miss,
0:15:06 > 0:15:10it is, of course, quite easy to leave your umbrella at home
0:15:10 > 0:15:13when it's going to rain, or just to leave it anywhere,
0:15:13 > 0:15:16but this connects to your mobile phone so it should stop
0:15:16 > 0:15:18you from being able to lose it.
0:15:18 > 0:15:21If you move too far away you will receive an alert
0:15:21 > 0:15:24and if you wake up in the morning and the Internet says
0:15:24 > 0:15:25it is going to rain?
0:15:25 > 0:15:29Well, you will get a reminder on your phone to make sure that
0:15:29 > 0:15:31you take it out with you.
0:15:31 > 0:15:33The problem was, I did seem to get more alerts
0:15:33 > 0:15:34than were actually required.
0:15:34 > 0:15:37If you are taking a trip to the beach this summer,
0:15:37 > 0:15:41then hopefully your issue won't be rain, but it could be thirst.
0:15:41 > 0:15:43So, if you've been waiting for a drink delivery service
0:15:43 > 0:15:48to bring cold drinks to your sun lounger,
0:15:48 > 0:15:50then you are in luck.
0:15:50 > 0:15:52Well, at this Estonian resort, anyway.
0:15:52 > 0:15:55The Cleveron drone aims to safely drop-off drink orders
0:15:55 > 0:16:00from two meters above.
0:16:00 > 0:16:04I'm not sure I would opt for something fizzy...
0:16:04 > 0:16:06The company claims this is the fastest response time ever
0:16:07 > 0:16:11for commercial drone delivery.
0:16:11 > 0:16:16So whatever the weather has in store for you this summer,
0:16:16 > 0:16:22you now know how much better prepared you could be in the future.
0:16:22 > 0:16:26I seem to be living in a time when all of the Tech
0:16:26 > 0:16:28from my favourite childhood sci-fi films is coming true.
0:16:28 > 0:16:32We kind of have Back To The Future hover boards, we do have jet packs
0:16:32 > 0:16:35from the James Bond films, and robot vacuum cleaners
0:16:35 > 0:16:40from The Jetsons.
0:16:40 > 0:16:43And Kate Russell has been to Stuttgart in Germany to uncover
0:16:43 > 0:16:45the latest storybook tech turned real.
0:16:45 > 0:16:53The picturesque town of Rottweil, Germany.
0:16:53 > 0:16:56Home to fearsome dogs...
0:16:56 > 0:16:58Chocolate box buildings...
0:16:58 > 0:17:01And a 246 metre tower housing the tallest observation
0:17:01 > 0:17:06deck in Germany.
0:17:06 > 0:17:08That this tower isn't just about great views.
0:17:08 > 0:17:11Built by elevator company thyssenkrupp, it has 12 lift shafts
0:17:11 > 0:17:14running inside of it.
0:17:14 > 0:17:23One is used to transport passengers to the top.
0:17:23 > 0:17:26The others to test the latest in elevator technology.
0:17:26 > 0:17:28As buildings get taller, life gets more complicated
0:17:28 > 0:17:31for elevator engineers.
0:17:31 > 0:17:34If a building is reaching a certain height, it has the tendency
0:17:34 > 0:17:40that the wind and the sun brings a certain sway to it.
0:17:40 > 0:17:43It's actually a big problem for the traditional elevators.
0:17:43 > 0:17:46If the frequency of the ropes equals the frequencies of the building
0:17:46 > 0:18:08swayed, you get harmonics and things happened which are not so good.
0:18:08 > 0:18:15To counteract this sway, thyssenkrupp have installed a mass
0:18:15 > 0:18:17dampener, weighing in at 240 metric tonnes.
0:18:17 > 0:18:21It can also be programmed to create sway and test how their tech handles
0:18:21 > 0:18:21different weather conditions.
0:18:21 > 0:18:24There's also the thorny issue of what happens
0:18:24 > 0:18:25when things go wrong.
0:18:25 > 0:18:28The tower houses a 250 metre fall shaft, which is used to drop things
0:18:28 > 0:18:31from a fantastic height, to see how they break...
0:18:31 > 0:18:31Argh!
0:18:31 > 0:18:31Whoa!
0:18:31 > 0:18:33That's going to -30 into the ground.
0:18:33 > 0:18:36That's mad.
0:18:36 > 0:18:37That makes me feel quite dizzy.
0:18:38 > 0:18:41The tower is also used to test ideas designed to tackle some
0:18:41 > 0:18:43of the biggest problems facing high-rise living.
0:18:43 > 0:18:51Already today, lifts take about 40% of the usable space of a building.
0:18:51 > 0:18:54If you build higher, you need more lifts,
0:18:54 > 0:18:57and you are ending up with only lifts, which makes no sense.
0:18:57 > 0:19:01So our inside area is in the core of the tower.
0:19:01 > 0:19:05And only a few people really have the chance to see
0:19:05 > 0:19:11what we have built, and what is running there.
0:19:11 > 0:19:14An elevator without any ropes, so this is something revolutionary.
0:19:14 > 0:19:16Instead of steel ropes, the cabin is carried
0:19:16 > 0:19:17by linear motors.
0:19:17 > 0:19:20The same tech that drives Japan's bullet train at 500
0:19:20 > 0:19:24kilometres per hour.
0:19:24 > 0:19:26As well as eliminating the speed and height restrictions of today's
0:19:26 > 0:19:30tech, it allows passengers to travel sideways as well as up and down,
0:19:30 > 0:19:32just like Willy Wonka's fantastical elevator in Charlie
0:19:32 > 0:19:37and The Chocolate Factory.
0:19:37 > 0:19:40Behind the scenes, behind the car, we change this exchanger 90 degrees.
0:19:40 > 0:19:43Get prepared for the horizontal movement while people are entering
0:19:43 > 0:19:47and leaving, and as soon as the doors close, we can go
0:19:47 > 0:19:48sideways to the next shaft.
0:19:48 > 0:19:51This is the most important thing, that we come back
0:19:51 > 0:19:52to a circulating system.
0:19:52 > 0:20:00So reinventing the Paternoster.
0:20:00 > 0:20:03Using this circulating pattern means a lift shaft could hold ten
0:20:03 > 0:20:05or more cabins.
0:20:05 > 0:20:08Much more efficient than the single up-and-down ride today's elevators
0:20:08 > 0:20:11are limited to.
0:20:11 > 0:20:15And this will only become more important when we start looking
0:20:15 > 0:20:23at elevators reaching perhaps 1,000m or more into the sky.
0:20:23 > 0:20:28That was Kate, and that was amazing.
0:20:28 > 0:20:31Not that the most impressive innovations always have to be
0:20:31 > 0:20:32the highest-tech, of course.
0:20:32 > 0:20:37As I've often said, some of the most inspiring innovations are those
0:20:37 > 0:20:40in the developing world, that use pretty low technology
0:20:40 > 0:20:42to do really important things.
0:20:42 > 0:20:46Case in point - Dan Simmons heard about a group of people
0:20:46 > 0:20:49who are using a mobile phone to save lives in Nairobi.
0:20:49 > 0:20:53I'm on my way to Thika, an hour's drive south of the capital
0:20:53 > 0:20:56to see one of the first centres in Kenya using phones
0:20:56 > 0:20:58to diagnose cancer.
0:20:58 > 0:21:02It's essentially a smartphone with a scope offering
0:21:02 > 0:21:0442-times magnification.
0:21:04 > 0:21:07That allows the camera to be placed a comfortable distance away
0:21:07 > 0:21:11from the patient.
0:21:11 > 0:21:14A powerful light comes with the system.
0:21:14 > 0:21:17Its even brightness is critical to avoid misdiagnosis.
0:21:17 > 0:21:22Violet, what is the biggest change that you have seen since this
0:21:22 > 0:21:25was introduced to your clinic?
0:21:57 > 0:21:59So you show them the picture...
0:22:00 > 0:22:01Yeah.
0:22:01 > 0:22:05And you say, you tell me which one of these you are?
0:22:05 > 0:22:09So they do their own diagnosis?
0:22:13 > 0:22:17So they are going to do you out of a job, if they can
0:22:17 > 0:22:19do their own diagnosis with a machine!
0:22:19 > 0:22:20LAUGHTER.
0:22:20 > 0:22:22They are not going to need Violet anymore, are they?
0:22:22 > 0:22:23Yeah!
0:22:23 > 0:22:25Many women do not go for the screening.
0:22:25 > 0:22:31It has been too expensive, and because of a lack of education,
0:22:32 > 0:22:36many who do go feel it's a waste of time if they get the all-clear.
0:22:36 > 0:22:39That's why Violet's job is to explain as well as test.
0:22:39 > 0:22:41I use this to check your cervix...
0:22:41 > 0:22:46Scans used to cost $40 to $50 - over half a week's wages.
0:22:46 > 0:22:49This scan costs $10.
0:22:49 > 0:23:02When a patient comes, you view their cervix
0:23:02 > 0:23:05you have an opportunity to address them, you have an opportunity
0:23:05 > 0:23:10to talk to them about cervical cancer.
0:23:10 > 0:23:15So the hurdle that was previously there was education in relation
0:23:15 > 0:23:19to cervical cancer.
0:23:20 > 0:23:23But now we have seen an improved attitude
0:23:23 > 0:23:26toward cervical cancer, and increased screening.
0:23:26 > 0:23:29And, with this, we can screen any woman, anywhere.
0:23:29 > 0:23:31The system isn't cheap.
0:23:31 > 0:23:35It is sold at $2,000 a unit, but it has already seen an 80%
0:23:35 > 0:23:38increase in the number of women being scanned at this clinic over
0:23:38 > 0:23:39the last year.
0:23:39 > 0:23:42If Kenya's new government decides to back the scheme,
0:23:42 > 0:23:44it could become a major weapon against a major killer.
0:23:44 > 0:23:47That was Dan, in Nairobi, and that's it for this week.
0:23:47 > 0:23:51Over the next couple of weeks, we're going to give you the chance
0:23:51 > 0:23:54to rewatch two of our favourite programmes from the year so far -
0:23:54 > 0:23:56the two India specials.
0:23:56 > 0:23:59We'll be travelling across the country to meet
0:23:59 > 0:24:04the people working hard to change lives, save lives,
0:24:04 > 0:24:08and maybe one day discover new life.
0:24:08 > 0:24:12I hope you enjoy watching them as much as we enjoyed making them.
0:24:12 > 0:24:16Do not forget we are on Twitter and on Facebook.
0:24:16 > 0:24:19Thank you for watching, and we'll see you soon.
