this is bbc news. the headlines: exit polls in ireland's referendum on abortion suggests a substantial majority support liberalising the country's strict laws. with the votes still to be counted, taoiseach leo varadkar — who supported the campaign — says it looks like ireland "will make history". the film producer, harvey weinstein, has appeared in court in new york charged with rape and sexual abuse. the prosecutor said mr weinstein used his position and power to violate young women. his lawyer says he intends to plead not guilty. president trump says he's having very productive talks with north korea to reinstate the summit talks. in his latest tweet he said the meeting with kimjong—un might take place next month after all. the summit had been called off because of what he called the open hostility shown by north korea.

in about ten minutes we'll have this week's edition of newswatch. but first, it's time for click. 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 fit 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. 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, you can see your alpha waves, your gamma waves, your beta waves there. 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 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? 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 at sheffield doc/fest onjune 7. and after that, the caravan will hit the road across the uk. 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.

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 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 use‘s 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, you know, we trained a model based on, you know, anticipated guests, you know, we were getting the 70—80% accuracy.

it was moderated by the researchers who had curated all the training material for the ai service in the first place, yeah, so they were very familiar with the names, the people, the faces. 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. 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. 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 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. 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 you get upset on the internet, always tell your parents. 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. but two—year—old emily here is part of a study they could change the way we perceive 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 that can be used in different ways. so we wanted to make sure that we were doing studies about these new devices. and that means there is not much science out there right now. a lot of the concerns parents have are 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.

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 is it for the shortcut of the programme this week. full—length version is available for you to watch right now. and here's the thing, if you are at the high festival this weekend, so are we. we are doing a live programme which you can see next week. in the meantime, get in touch with us through our social media. thank you for watching, see you soon. hello, and welcome to newswatch. one week on from that royal wedding, did the sinews get its coverage right, or get caught up in the further? and we re or get caught up in the further? and were important stories like cuban

plane crash in the us school shootings were a side? this week provided reminders of two recent tragedies with the opening of the enquiry into the grenfell tower and the first anniversary of the manchester arena bomb. it was marked on tuesday by a number of bbc news programmes and reports, and also by a bbc two documentary, the night of the bomb, which traced the movements of the bomber, salman abedi. and the police tell us the place where it was put together was this flat right in the heart of the city centre, which meant that he didn't have far to go at all. although that programme was widely praised, the

chief constable of manchester police wrote an open letter to the bbc accusing the bbc of wholly inaccurate reporting, and showing footage of the aftermath of the bomb which was newsworthy viewing at the expense of the families. he went on: those charges echoed by some members of the public were rejected by the bbc, he said in response: the issue of respecting or upsetting

relatives and friends of the victims
