hull, but then the sun example in hull, but then the sun should be, and when it is, once again, across the south, you could see that thunderstorms popping off randomly scattered around there, giving us thunder, lightning and gusty winds, as well. this is bbc news, our latest headlines. politicians are calling for northern ireland's strict abortion laws to be liberalised, after voters in the irish republic overwhelmingly backed changes in their referendum. us officials are reported to have travelled to north korea for talks on the possible summit between president trump and kim jong—un. the environment secretary michael gove has ordered a review of national parks in england, which could result in the creation of a new wave of protected areas. storms and torrential rain swept across southern britain overnight, with spectacular displays of lightning. around 15,000 strikes were recorded. now on bbc news, click.
3:31 pm
this week: we are striking a pose. finding the fruit. and asking the scary questions. lara lewington: what about if there were no mobile phones? gasps. how are you feeling today? what's happening? i'm putting emg sensors on your trapezoids. are you? on my trapezoids? yes. me, i'm a little embarrassed due to the nature of the outfit. which, of course, is bright green.
3:32 pm
this makeshift motion capture suit is going to measure my emotions. at university college london, researchers believe that it's cues in your body that give away your emotional state. using multiple sensors, this bodysuit measures my movements, energy and posture — all strong indicators of how i'm feeling. what? the work here at ucl aims to help detect stress in workers, measure psychological states, depression and pain, and aid rehabilitation. if you are embarrassed, you close yourself, you tend to hide. we, for example, study how people laugh when they are embarrassed and when they laugh because they are really happy and there is a very different type of movement. right. so when you are more positive, you tend to open, you're proud of yourself, you tend to open your shoulders, they aren't tending to be more slightly more far away from your body.
3:33 pm
is this better than looking at someone's face to judge emotion? in very emotional situation, we have been shown data that the body is much more informative than the face. if you want to hide your emotion, you control your face and you forget about your body, so the body leaks or you over control the body so you just do move any more, and we know something is wrong. and, of course, then we can also measure information about the dynamic of the movement, the speed, the jerkiness of the movement. if you are angry, you tend to have thisjerky movement. nadia and the team have also developed a novel use for your smartphone. using infrared sensors, this phone has been rigged to detect stress levels through your breathing patterns. to put it to the test, the team gave me some maths problems to solve — yes, just like being back at school. brilliant! beep! klaxon.
3:34 pm
oh, what? klaxon. oh, no, got that wrong! suddenly, i'm really stressed. nadia hopes to eventually put these kind of sensors into clothing to help patients and people in pain. this emotional insight is valuable in other ways, too. there are some people, such as people on the autism spectrum, that tend not to be able to interpret actually the emotions and the expressions of themselves and the people that they see, that they communicate, so in that sense, we can make claims that training or creating computing technology might be better than them in terms of such interpretation or can even help them as assistive technologies. and you are forgiven. facial expressions obviously give away a whole host of non—verbal information and there are companies who are trying to uncover your hidden reactions to better market their products. emotional data can be used against us because we always feel something. so although we think we are logical beings, research shows that even
3:35 pm
when we are not aware or even when we are not conscious, we always have a feeling about things. you like it or not, you dislike it or not, and that actually affects our decisions, affects even our learning, our attention, all of that. your emotional responses are a key component in purchasing, even if you don't realise it, and companies want that crucial emotion data. welcome to the world of neuromarketing. realeyes, whose clients have included mars and lg, specialise in emotion detection and neuromarketing. they use facial cues to gauge consumers‘ reactions when viewing adverts, so that messages can be refined to hit the right spot. and i'm putting that to the test with the help of some classic bbc clips. play it nice and cool, son, nice and cool, you know what i mean? laughs.
3:36 pm
using just a webcam, realeyes are going to measure my emotional response. so you are clearly mapping features of the face here, and is it enough to look at the eyebrows to see surprise and the curve of the mouth to see happiness or sadness? yeah, the face is surprisingly revealing. we humans understand body language quite well, it's a huge part — it's, some say, 80% of our communication — but computers have not had the ability until now. right now, we work within marketing because emotions drive what people do. the more people feel, the more they tend to do, so we see in real time how people respond and pick up that signal of where is the true emotional connection between a brand and the audience? many people would find it creepy that their computer is starting to read their emotions and possibly
3:37 pm
tailor what they see, either to influence them orjust to respond to their emotions. in that sense, i don't think the emotional analytics is any different to any new technology. people are always sceptical in the beginning and what tends to happen is that then at some point when this technology really starts to help people in different ways, then they understand the value of it and it becomes normal. emotion and data are combining in ways that will radically transform our relationship with machines. that could be advances in medical diagnoses, orjust to learn more about our strange human sense of humour. my apologies. laughter. and imagine this — in the future, your emotions could influence the things that you watch.
3:38 pm
jen copestake has been to see a film where the plot changes, depending on your reactions. as our world becomes more augmented by technology, the lines between fiction and reality are blurring. very soon, we may be able to entertain ourselves in these new realities simply by using our thoughts. i'm here at the university of nottingham, where i mightjust see the greatest film that's ever been made, because it's being made by me, using my brain waves. this must be it. this tiny adapted caravan is where i will watch the movie my mind would most like to see. so we're just going to fix you with this eeg headset, clips on, and then there's a sensor on your forehead as well. so this eeg headset is monitoring my brain activity? yeah, it picks up eeg data, the really tiny electrical signals sent off by the firing of your neurons. so the signal is good. we will press play.
3:39 pm
enjoy. i rememberyou had become all these different people. there are three simultaneous narratives that my brain can dip in and out of to make up a unique film, with over 101 trillion possible combinations per viewing. is that my brain activity now? this is your data, yes, so you can see your alpha waves, your gamma waves, your beta waves there. and they are just sending out a string of numbers. the more focused my brain is, the longer the scenes are, and the more the narrative holds together. if i lose focus, the computer cuts the scenes more rapidly. so it's a pretty surreal experience watching a film that you're creating as you're going along. the whole concept behind this project as a whole was it was inspired by what was happening with these social media bubbles that are still about, but during, like, 2016, we saw gamergate, with brexit, with the american election, and how, like, a small group of people could influence larger groups. the moment is designed to be
3:40 pm
watched twice in a row by groups of around five, where two people take turns watching the movie with the headset on. people then observe the different ways the narrative changes. so, how did you find the film? ah, really interesting. did it make you think about your relationship with technology? ah, for me, yeah, and also, like, a little bit about, you know, like, society, about, like, people not thinking about what they are doing. i always prefer having an artist picking a message for me and then it does whatever it does to me, rather than me making my own message. it feels like i would be living in my own bubble. i would like the artist to pick the film for me. i don't want to live inside my bubble any more than i already do. it's a bit scary, isn't it? it is a bit scary, yeah, it's a bit scary. what my endgame really is, just to ask people to consider critically the technology that we use and why it is being used in that way. the moment has its world premiere
3:41 pm
at sheffield doc/fest onjune 7. and after that, the caravan will hit the road across the uk. hello, and welcome to the week in tech. it was the week that facebook boss mark zuckerberg apologised to members of the european parliament for the compa ny‘s role in the cambridge analytica data scandal. his apology didn't go down well, though, as zuckerberg was accused of not answering many of the questions put to him. publisher epic games announced that it will be offering a prize pot almost £75 million for its upcoming fortnite tournaments. the bumper bundle of readies is believed to be the biggest sum of money ever offered for an esports event. it was also the week that barack and michelle 0bama signed a multi—year deal with streaming giant netflix to produce content that could potentially include scripted series, unscripted series, docu series, documentaries, and features.
3:42 pm
that should keep them busy for a while! and you might think that acrobat is one job which is completely safe from the upcoming robot revolution. well, think again, as no less than the disney research hub have shown off stickman — an acrobatic robot that can backflip through the air. stickman uses inertial motion sensing, laser rangefinders and computer vision to stick that perfect landing. well, kind of! fanfare. ah, the royal wedding — a once—in—a—lifetime opportunity to see history unfold, drink pimms, and spot the stars. so many faces to see. so many stories to know. but we can't all have access to thousands of pages of scintillating who's who information like me. oh, look! it's william guy vestey, the eldest son of samuel and cecilia vestey!
3:43 pm
he is married to violet henderson with whom he has, yes, one daughter. fascinating! and fortunately, this royal wedding, you don't need any of these to stay in the know. this is who's who. it's a website for phones and desktops that uses artificial intelligence to automatically recognise all of those royal wedding guests. from the famous to the more obscure, each guest's face is tagged with their name and some background info. plus, the tool lets you skip around to watch your favourite guests arrive. built by data company greymeta and broadcast by sky news, it's the first time they have used facial recognition for a live broadcast. who's who, our royal wedding project, was an opportunity to use machine learning and artificial intelligence to find a different way of telling a story. we knew that with celebrities, viewers would be able to identify them without the software. we also knew there were large numbers of members of the royal family, particularly the extended
3:44 pm
royal family, who, while public and therefore we would be able to identify them, wouldn't necessarily be obvious to our viewing public. what we were able to do therefore was identify them as they arrived at the ceremony, as well as some of the better—known celebrities, to give a richer experience. behind the scenes, who's who uses amazon's cloud—based rekognition system. throw photos or video at rekognition and deep learning algorithms are put to work to try and figure out what exactly is going on. that's easy enough for us humans but for computers, understanding what's happening in videos and images is no simple task. this is what amazon rekognition looks like behind the scenes. i have just uploaded a clip from last week's click and in a few minutes, it has given me this list of people, objects and activities that it thinks it's found in that video. things like this bloke cycling, the faces of these bystanders, and click host and celebrity urban mayer? the facial recognition today isn't perfect. even though, we you know, trained a model based on, you know, anticipated guests, you know, we were getting
3:45 pm
70—80% accuracy. it was moderated by the researchers who had curated all of the training material for the a! service in the first place, yeah, so they were very familiar with the names, the people, the faces. but even if you don't know your meghan markles from your angela merkels, techniques like these are already finding uses in other areas. last year, the new york times built something to help reporters recognise members of congress. dubbed "shazam but for house members‘ faces," who the hill lets journalists text in photos which are then analysed in the cloud for familiar faces. like sky's who's who, the recogniser is trained on existing pictures of members of congress to make it more accurate. but would you like the idea of being instantly and automatically identified without your consent? well, this week sees the start of gdpr, the eu's new, stricter data legislation, which may mean that tools like these might no longer be legal.
3:46 pm
we were looking at public people in a public environment where they are expecting to be recognised, which gives us implied consent. in a post—gdpr world you need exposing consent, which means that if we wanted to run this thing in the future we would have to contact people and say this is what we are doing in a particular environment. we would consider that if we go forward with this project, or we may consider to do alternative things with this type of technology. just this week amazon found itself in hot water after it was found that they had been marketing recognition systems to law enforcement agencies in america. as technology like this because more accurate and widely used, we could all be as recognisable as the royal family. that was steve and his bunting. and if you want to try image recognition for yourself, you could have a go with the blippar app, which is doing a good job recognising objects as well as faces. for certain types of objects,
3:47 pm
it has been trained on specially curated datasets, categories like cars, landmarks, works of art, dogs and cats and flowers, which means that once it has recognise an object it can go into quite a bit of detail about it. and also show you its knowledge graph which is a web of all be connected themes that surround the object that it can see. blippar is really made for augmented reality marketing campaigns and also educational experiences, which means it's better at recognising some things than others. and, let's face it, it is trying to do to really hard tasks, here: first pick out an object in the scene, and then somehow match it to its training images. but it can recognise more general objects under the right conditions. the things it finds hardest to recognise are objects which are deformable, floppy, and don't keep their shape, like clothing
3:48 pm
and politicians‘ opinions. and yes, it can also do famous faces. it‘s trawled the web to pull in photos of about 500,000 famous people in figures. in fact, it can even recognise not so famous faces, like me. it also recognises faces that are usually hidden behind sci—fi masks, for example, and it even gets karl howman from brush strokes. and that, yeah, that‘s definitely lara, who has been to wimbledon‘s polka theatre, where they are running workshops on how kids can stay safe online. inevitably, kids today are growing up surrounded by technology, and there are pros and cons to that. but the issue is that grown—ups are still learning how to handle it. i can see you eager beavers
3:49 pm
are ready to start the game. so here at the techtopia festival at wimbledon‘s polka theatre, they‘re hoping to help with creative ways to get the kids thinking. the objects represent different websites. the digiplay workshop here is about teaching kids to safely navigate online. it also encourages them to think about what they are going to share and how they are likely to be perceived as a result. after all, this lot are already pretty active web users. life without the internet, it would be the worst. i would just die straightaway. if there is no internet. what if there were no mobile phones? squeals. they do have a few concerns. one of the worst things is on your homepage and not knowing your password. the worst thing is when they get a virus. they talk a lot about internet safety, so don‘t share your details
3:50 pm
with strangers, don‘t click on links in e—mails and that sort of thing. but they don‘t talk about what goes on underneath — what information the platforms are collecting about you. what we aimed to do was to raise awareness about how the online world is governed by algorithms and the types of data people share online, and the information that goes online. and what i did was a series of projects with 13—17—year—olds, and they are already pretty savvy. they have grown up online so they know what they are doing. um, but they‘re not sure how everything works. now, today, working with the younger ones, sort of 8—and—9—year—olds, it is really fascinating to see they have the same knowledge about this stuff and they are aware and their parents have already kind of brought them up to stay safe but not necessarily know what is going on in the background. but after today, they seem brimming with knowledge. use the internet safely and don't go on websites that you don't know about. make sure to keep all your personal stuff safe on the internet so nobody steals them. if get upset on the internet, always tell your parents.
3:51 pm
maybe not surprising when they are part of a generation they can end up surrounded by screens from day one. even if they start off as the forbidden fruit, it‘s not long before parents are weighing up the benefits versus the concerns. and two—year—old emily here is part of a study they could change the way with perceived screen time. researchers are three years into their quest to find out what the long—term consequences are likely to be. here, it‘s all about keeping focus on the apple while attention is being called upon elsewhere. the kids‘ reactions are being recorded, and they will be combined with markers in their day—to—day lives. parents have a lot of assumptions and maybe fears about how the screens may be influencing their child‘s behaviour. but a lot of the science behind that is actually based on tv, which is a very different experience to these interactive mobile devices
3:52 pm
that can be used in different ways. so we wanted to make sure that we were doing studies that these new devices. and that means there is not much science out there right now. a lot of the concerns parents have not been backed up by scientific evidence. we have found that within the children who are using the touchscreen devices, that the earlier that they actually use a device interactively, the earlier that they reach real world motor milestones. so, for instance, if you are playing with a kid, one of the milestones you can look at is if they can stack blocks together. and we found that the kids that actively use a touchscreen earlier are reaching that real—world milestone earlier. but, importantly, we have not seen any signs of delays in language development or in whole body movement development — so walking or crawling, which some parents might have been concerned about. the study also looks at how kids regulate themselves the point
3:53 pm
at which they might choose to switch off. make sure you interact the real world and don‘t stay online too long. everybody knows it can be lonely when you start a new school. this interactive experience explores the idea that technology may make us feel pulled in many directions. but sometimes we need to focus. because i don't suppose they get out much. and that focus should probably not be on taking selfies. or not according to this, a one—woman show at the festival, entitled random selfies. it highlights the loneliness that children — or anyone — can feel in our increasingly connected world. so, it is about loretta, an 11—year—old girl. it is basically about her discovering loneliness for the first time. and being in a world that is very heavy social media. so being included in that but feeling that distance. what do you hope that people will go away thinking and feeling after seeing this? i think one of the main things is that loneliness is present,
3:54 pm
it‘s there, but also that it‘s just about communication, and just about opening up and being able, as loretta is, to express herself to people what it is to be lonely and to develop this realisation that it‘s not just her, and although the social media platform is perhaps making herfeel distant, it can be positive, because you are connecting with people. meanwhile, the kids are clearly enjoying the workshops, proving, if nothing else, they still know how to have fun, when there‘s no phone or tablet to hand. that was lara looking at some of the efforts to help young people to get to grips with this crazy digital world that we‘re all living in. talking of craziness, if you‘re at the hay festival this week, so are we. we are doing a live show me some of which you can see in next week‘s programme. in the meantime, you can get in touch with us before that on facebook and twitter at bbcclick.
3:55 pm
thank you for watching. we will see you soon. while thunderstorms are breaking out across some parts of the country, many of us are enjoying the fine sunny weather. it‘s the south that‘s getting the real action on the weather front. these are the storms that happened last night, sweeping across the south and moving further north. the thunderstorm risk will continue across the southern half of the uk for the next few days. it‘s this very volatile atmosphere across western parts of europe. there are some terrific thunderstorms brewing in france and germany at the moment. we are seeing some of our own home—grown thunderstorms, but this pattern with that warmth coming in from the south
3:56 pm
is going to be with us for the next three days. hence we anticipate further storms. here is the forecast, second half of the day very warm if not hot in the south. most of us seeing temperatures into the 20s. these showers randomly occurring across the southern portion of the uk. overnight tonight across the north it‘s going to turn misty and murky. a lot of low grey cloud forming, some of it drifting off the north sea. for places like leeds, sheffield, hull, newcastle and the aberdeenshire coastline it will be a very cloudy start to the day and will take time for it to melt away. then the sun will be out and we are in for another beautiful day across many northern and north—western parts. once the sun comes out, those showers will be popping off across the south. some of them will be nasty downpours with gusts of wind and terrific lightning displays. you can see how warm it is. those showers will continue into tomorrow evening.
3:57 pm
difficult to say which town and city will get it at what time. we can only talk of areas rather than specific locations. high pressure across scandinavia means the winds are blowing out of the east. this is why we are seeing most of the storms in the south. it‘s today with the wind pattern, this atmosphere is rotating around the southern part of the uk. you can see the storms across the near continent with some of them forming and drifting in our direction. for the next few days it‘s going to stay pretty warm with a storm chance continuing through week. this is bbc news. the headlines at 4.00pm. senior politicians call for northern ireland‘s strict abortion laws to be relaxed as voters in the irish republic overwhelmingly back change in a referendum. preparations are under way for a next month‘s summit between the leader of north korea, kim jong—un, and president trump.
3:58 pm
the government is considering whether to expand england‘s network of national parks and areas of outstanding natural beauty. spectacular overnight storms across southern britain — around 15,000 lightning strikes in just four hours. coming up in the next hour: agony and anguish for liverpool fans. two glaring errors from their goalkeeper help real madrid to a 3—1win in the champions league final in kiev. more big acts perform on day two of the bbc‘s biggest weekend across the country.
