dotted around but much of england and wales, temperatures up to 26 degrees. into tonight, from clear skies to cloudy ones across much of scotland, much of northern and eastern england, low cloud rolling off the north sea, but temperatures in double figures, and a muddy start to monday morning for many. it will feel cool across the eastern coast, inland it will break up at times, the further south and west you are, one or two isolated showers breaking out in the sunnier spots, but temperatures into the 20s, just the teams down through eastern coast. during the rest of this week, more in the way of sunshine developing, temperatures on the up a little bit, just one or two showers, too. this is bbc news — our latest headlines: one year on from the the terror attack on london bridge and borough market — a special service will be held at southwark cathedral to remember those who were killed and injured. the home secretary, sajid javid, has said he'll look

again at key parts of immigration policy — including foreign students and doctors coming to the uk. g7 finance ministers have urged their american counterpart to pass on their "unanimous concern and disappointment" to president trump about new us import tariffs on steel and aluminium. the church is campaigning to root out the exploitation of workers at car washes who are trapped by threats and debts. now on bbc news, it's time for click. this week: it's hey from hay. a walkabout in washington. jiggly monsters. and that shouty game again. a bit of rain, a bit of sun

and a lot of books — that's the world—renowned hay festival. once a year, the small town of books, hay—on—wye, on the england—wales border, hosts thousands of visitors ready to fill their boots with fact, fiction, opinion and debate. growls and scientists and big thinkers. and, when you've done all that, you can come and see us too. for the third year in a row, we've been invited to show off some cool tech before a live audience. of course, we turned someone into communist revolutionary vladimir lenin using vr! why wouldn't we?

do you actually feel like you're there then? yeah. 0k. i can turn around and i can see everything, like, i've got a whole room. and we played mind games with neurologist doctor hannah critchlow and albert einstein. even though you know that it's the wrong way round, i cannot help seeing that this is going the wrong way. anotherface is popping out, when actually, it's the back end of the mask. i was put on the spot with a challenge that gave me shivers and flashbacks to my mastermind appearance. oh, god! oh, my god! what does the g stand for in gdpr? oh, god! gregory! it's general. the island of tuvalu, which lies in the pacific ocean, midway between hawaii and australia, is located at which top level domain popular with television channels? what? .tv! and then there was click‘s very own patented shouty wavy game

that we call hay fever, as one half of the audience tried to push the other half off a see—saw. crowd shouts hay or wye. it's controlled using image and speech recognition — to make sense of all the waggling and yelling, you know. right, we're going to move on now and look at a piece of technology which aims to help blind people to navigate, well, anywhere, better. many blind people have fantastic spatial awareness but at events like these, and everywhere else, there are always things which will catch you out. gary o'donoghue‘s been testing a new pair of glasses in washington, dc. excuse me? could you show me down the steps, do you think? yes. oh, thank you very much. that's very sweet of you. you having a good day? strangers often ask me how

i cope with being blind. what i tell them is that most of the time, it's just a bit inconvenient. some of the time, it's a bloomin‘ nuisance. and every now and again, it's a total pain in the you—know—where. it's not so much because stuff is impossible to do, it's just it takes a lot longer, or you have to ask for other people's help. so what if there were a pair of eyes that you could call up at the touch of a button with a little help of some wearable technology like this? hey, erin, how are you doing? hi, gary, thanks for calling aira. i'm in washington, dc on the national mall, and right by the reflecting pool. this is one of washington's most popular tourist spots. but even though i've lived here for more than three years, i've never been able to experience this walk alone. but that just changed. so of course, you have the reflecting pool on your right—hand side, and i can see way off in the

distance the washington monument. what's helping me do this is a service called aira. the name a nod to artificial intelligence and, i'm told, something to do with egyptian mythology. egyptians aside, though, it combines a dedicated smartphone connected to new custom—made classes with a camera between the lenses with an impressive i20—degree field of view, both horizontally and vertically. tap a button on the phone twice and you're connected to a trained sighted agent who gets your video feed. while there are other apps that connect sighted help to blind people, it's the combination of the tech and the quality of the agent that makes this feel different. the tasks it can help with can be a simple or as complicated as you want, from booking a car to helping you keep up with your social media presence. as a journalist, i want to be able to access all platforms, and now, i can even independently post to instagram. that is spot on, so it looks very centred.

isee l, o, vand e. it took me a long time to, i won't say keep my mouth shut, but it took me a while to understand, you know, and, through the training process, understand what information is important and what information is not important. so it is — there is a bit of a learning curve — at least there was for me — to understand what was opinionated versus what wasn't. what are the things you've been asked to do? give us a sort of idea of the range of things. yeah, i think the simple tasks mean the most. so pulling expiration dates on the yoghurt in the fridge, to really serious things like describing a daughter's wedding or a father's funeral. so he could see how people were around him? yeah, how the room was set up and what the flowers looked like. you know, the ceremony was beautiful, and to give him access to that information that he typically doesn't have was sad but empowering. the service is currently available in america and has just launched

in canada and australia, with plans to expand to the uk. all the agents work from home and calls are priced per minute of their time. and they're working on a smart assistant that will automate basic tasks, like reading text or identifying barcodes so you don't waste minutes there. and in some places like airports, it's free. the airports will sponsor the service to pick up the cost while you're there, and aira draws a geofence around the location so you're not billed for the time. every disabled person has their airport horror story. if you're visually impaired, and if you ask for help, they tend to want to stick you in a wheelchair. so if this bit of tech can help me avoid that kind of episode, i'm up for it. it says, "scan your document's barcode." and go to the leftjust slightly and pause and select. yeah, so this is actually the back

of the receipt advertising for american express, and now it's upside down if you'll rotate it. ok, perfect. it takes a little while but it's doable, isn't it? that's amazing. there's a bench here on the right—hand side. you have a narrow path here and then you're going to have a bag on the left and a man on the right, so a very narrow path here. i know everyone talks about independence. it's not independence, it's choice. the issue is choice. normally when i go to an airport, you see, the most you can really ask of someone who's helping you, guiding you through, the most you can really ask of them is to show you where the loo is and possibly buy a bottle of water. after that, you're done. i want to shop! aira has adopted a subscription model, and while the hardware is free, there's a sliding scale for monthly minutes. it's not cheap. currently, 100 minutes set you back us$89. the unlimited plan,

us$329 per month. given most blind people are unemployed and those who work often earn less than average wages, isn't that a bit out of reach for most people? as we started to hear more about the financial concerns, we started to go to the businesses and say, "these are your customers, can you start to pay for the aira service?" so what we then did is added the guest programme. so again, today, you can sign up as a guest for free and use it in places that you go. would the big breakthrough be getting people like healthcare, health insurance companies, to pay for it? yeah. so active conversations now, you know, there's an estimated 300 million people globally that are blind and low—vision. we look at this as something where everyone should have aira in their hand and have this ability to have instant access to information any time, anywhere. this is one of a number of things out there to help people with visual impairments get around and identify objects. be my eyes recruits volunteers you can connect to on your smartphone and interpret your surroundings. microsoft's seeing ai app can

do text recognition, barcodes and other tasks too. and researchers at caltech have created a new app for hololens to act as a guide for blind people. they claim it takes advantage of the device's real—time spatial mapping capability, and it uses the hololens speaker to give directions. device: right turn ahead. so am i persuaded? there's no doubt that being able to do even small things at the time of your choosing feels great, but it's still expensive and, of course, there's the huge looming question of privacy. do i want to show a stranger my bank statement? in the meantime... i'm told there's a little ice cream stall not far from where i am. yeah, absolutely. let's go exploring. so... i think it's about time i got my long—suffering producer a treat. ooh, that looks good. we've got those here as well. yes, at hay we've been very busy, and we met up with helen margetts from the oxford internet institute to discuss digital platforms and her thoughts on where they might go in the future.

i think the key positive thing about digital platforms and the fact that we spend so much of our lives on digital platforms, digital, data—intensive platforms, is that they make, sort of, small amounts of things, tiny acts of participation in new domains possible. they make it possible for us to do a little bit of politics or start a — have a little bit of a business, or be a little bit of a taxidriver on uber. and that has a potentially very democratising, kind of, equalising effect. but you're here at hay notjust to talk about the positives, you're giving us a warning and hopefully, some kind of solution as well? of course. because the phenomenon i've described also applies to bad things.

it makes hate much more — hate speech much more accessible to people who, in an earlier time, mightjust have indulged in dark thoughts in the privacy of their bedrooms. and because these platforms are so embedded in our political lives, our social lives, our economic lives, there is a real need for our institutions, oui’ systems of governance to catch up. is there a solution? well, i think the solution‘s got to come from — it's got to be a sort of multilevel approach. one of them is, kind of, working with internet corporations, as well as regulating. it's about education at all levels. it's about educating... of users, education of users or education of the companies? you know, "this is how you should act." well, i was thinking first of all of people. do we teach our children the right things at schools? we teach them various skills, like how to prepare a cv, but do we teach them how to do a good profile on linkedin? you need to educate the educators?

we need to educate the educators, certainly. but finally, we need to educate the policymakers. forfar too long, policymakers have been allowed to pootle along, saying, "oh, i'm a technophobe, i don't really understand any of that stuff." you know, these platforms are embedded in every area of life. you can't be a decent legislator, a decent policymaker, if you have no understanding of data—intensive digital platforms based on algorithms, with all that entails. so it's not an option anymore i think — look, they should have to do all sorts of tests on their understanding of these things, otherwise you can't be governing effectively. hello, welcome to the week in tech. it was the week that a tesla in autopilot mode crashed into a police car in california. the driver sustained minor injuries after deciding to take a break from the wheel.

uk drone users could soon face a fine if they do not undertake an online safety test before taking to the skies. and virgin galactic has completed its second supersonic test flight in two months, yet again sparking talk that an out—of—this—world trip could be edging closer. if you're a street performer, london may be the place to be. buskers in the city can accept payment via contactless as well as small change, thanks to a partnership between busk in london and the now paypal—owned swedish tech firm izettle. wondering whether it's worth installing solar panels in your home? google's project sunroof now aims to help homeowners in some parts of the uk find out what savings they could make. it combines machine learning with google earth and maps data, local weather information, and property features,

like the angle of your roof. and finally, ever wondered how tight a compression bandage should be? well, engineers at mit have created a colour—changing one to help. high—tech light—tra nsmitting fibres are woven into a conventional bandage, causing it to change colour according to the pressure levels. probably not so great if you're colour blind, though! the hay festival is a place to share ideas, to collaborate, and to think about the future. one project which debuted this year was trans.mission, from the uk's natural environment research council. leading scientists were paired with award—winning artists to create works that would shed light on the science. children's author and illustrator chris horton works with climate scientist dr emily shuckburgh to create an animation looking at emily's work and to provide a warning on climate change. man: over time, this snow packs together. it crushes under its own weight so

tightly that it becomes solid ice. but it isn't completely solid — it contains tiny bubbles. at the research base, they have ice cores from all the way through the years that they have taken. i saw ice that was 140,000 years old and all of it has, like, these tiny little air bubbles in it so, they — well, they do lots of different measurements from the ice, but with the air bubbles, they measure the c02 and other parts of it, and sort of chart them through — through the ages. so what are the co2 levels that we are recording today? all gasp. they are much, much higher. this project is a great thing that, um, you're trying to tell the facts but yet do it with some emotion and make — allow people to connect with this information a little bit better. there are ways we can reduce our emissions and at the same time,

improve the quality of our lives. psychosis is a mental health problem which causes sufferers to perceive the world differently to those around them. and it can be a symptom of problems that we have heard of like schizophrenia or severe depression or bipolar disorder. but now, technology is being used to try and spot the early signs of psychosis and other mental health problems, as paul carter has been finding out. file: ect in the early days was a distressing business. the days of mental health problems being dealt with largely in the brutality of the asylum are thankfully now mostly behind us and now we see mental health as something to be treated and managed in a much similar way to physical health, aided by early intervention. and now, some fascinating research is using technology to help detect early markers of certain conditions. researchers in bristol and exeter are tracking the hand movements of volunteers,

seeing if they can devise early markers for psychosis. the hand movements are fed into mathematical models that catalogue features such as how many long and short movements a person has, along with their speed and duration. we are then putting all together this information, and this allows us to represent this movement as an individual motor signature. and everyone has a different motor signature? if we were to record your movement after three weeks later, we would be able to tell that this is your movement and not somebody else's. right. we can compare the motor signatures of healthy people with people with different mental disorders — in this case, psychosis. this study is based on previous research involving long—term schizophrenia patients, trying to see if it could also indicate people who are in the early stages of psychosis. although brad is working on the project as someone with previous experience of psychosis, just looking

at the results by eye doesn't tell you anything. using, like, appropriate mathematical tools, we can really understand this movement in a lot of details and then find the differences in these details between different populations of people. elsewhere, other research is looking at possible early markers of mental illness in children and young people. this random group of volunteers at a south london school are taking part in a study to see whether vr is a reliable way to detect if young people could be at risk of developing mental health issues. the experiment involves taking a virtual walk around their school canteen. what is special about virtual reality is that if you are immersed in this situation, you behave and think exactly the same as you would in real life. it is a way of more objectively measuring how people react in those kinds of situations. through the students‘ responses, researchers are able to look for signs of social anxiety and low—level paranoia. it feeds into a wider study looking at risk factors that can lead to mental illness.

meanwhile, this experiment has thrown up some fascinating results, like 64% of the students who felt anxious had also experienced bullying. and those who are — had a long period of feeling lonely during their childhood are much more likely to feel anxious and had sort of low—level paranoia in the canteen application. boys, it seems to be more prevalent that they feel more kind of anxious in these kind of situations compared with girls. that's interesting. it's against what we were expecting. while early signs don't mean that person will definitely go on to develop mental health problems, researchers believe it is certainly worth keeping an eye on. 50% of all adult mental health problems begin before the age of 15 and something like 75% begin before the age of 18. it's really important to thoroughly understand what may be risk factors, what may be protective in order to develop interventions. back in bristol, brad is trying to move like an avatar with what again looks like simple tracking that's actually taking

and producing detailed information. at this point, brad was trying to predict that the robot is going to turn, but actually, this didn't happen. we are looking at all of these details of how fast you are, like, you know, making this decision, how well you are following the movement of the robot. someone who perhaps might be suffering from psychosis, would you expect to see much more deviation between the two patterns? you really need, like, mathematical analysis to find these differences. if they were like, you know, really obvious, it wouldn't be necessary to use any sophisticated tool — you could just look at the person on the street and tell that they are suffering from some type of disorder. looking at the accuracy of both movement tests, there are no false positives. so we haven't classified anyone who hasn't schizophrenia as a person who has it. so 93% accuracy — that is a very high number, 93%. it is, it is on the level

of brain—imaging studies. project leads are hopeful for the role of technology in developing these early indicators, compared to traditional pen and paper tests. of course, the problem with mental health disorders and psychiatry in general is there is no blood tests for any of these disorders so it is just my impression of somebody else, somebody else's behaviour, or actually what they are choosing to tell me. and obviously, there is a whole raft of problems with that. this might be a more objective way to actually get over some of those inherent biases. and if it works, it will be very important because for the first time, we will be able to measure these abilities with some degree of accuracy and objectively. well, back at hay, it's deep concentration here in the scribblers hut. it's a digital animation and video mapping workshop run by mash cinema.

creepy laughter. we are creating monsters. and then we are going to animate them. we are using a free app called tagtool on these ipads. you draw the monsterfirst, and then you animate it. the idea is it's teaching these children more about the art of animation. the software is fairly intuitive. the animating function records the motion of your hand. creepy. because it's done on an ipad, you can literally create a 2—d digital creature or animated graffiti whenever inspiration hits. there's also a function that lets you collaborate on artwork with other tagtool users. i thought all the monsters here were equally scary, although here are some of our favourites. but it was after dark that they really came to life. the team went into guerrilla mode, projecting the creatures all over the festival site.

creepy music plays. and that's it from click at the hay festival 2018. hope you've enjoyed it. next week, it's world cup time, so we will be talking about the technology behind football, which apparently is a sport. in the meantime, you can follow us on facebook and on twitter, we live @bbcclick. thanks for watching and we will see you soon. hello there.

it's been a sunny sunday for some so far, bit of a soggy one for others. we've seen lots of rain across parts of central, southern scotland to stop the day. still some splashes of rain into the afternoon here and with some sunshine further north as temperatures rise, we could see some storms develop but nowhere near as many as yesterday. best of the sunday sunshine is really from southern parts of northern england, down through the rest of england and wales, further south you are, quite warm as well — 27 degrees. the showers in devon and cornwall gradually clearing away. but the afternoon showers chiefly focused around into the western grampians. this is where again there will be rumbles of thunder. isolated showers for northern ireland, but still a bit damp and grey across southern scotland, the very far north of england. one or two showers could break out elsewhere in northern england with very, very isolated ones elsewhere to england and wales. most places though finished the day dry.

mist and low cloud very close to north and eastern coasts of scotland and eastern coast of england and through tonight, that will become the dominant weather story as the low cloud rolls in off the north sea and pushes its way westwards. some clearer skies out to the west as the showers fade and temperatures for most in double figures into monday morning. quite a muggy start for the morning commute. so here we go with monday, it's going to be a good deal greyer across eastern england in particular. some of that also extending into the midlands. southern and western areas will see sunshine break through any cloud but does form. cloud that does form. one or showers here and there chiefly towards northern ireland. its western areas will see temperatures into the 20s yet again, but a cooler day down those eastern coasts. temperatures tomorrow, only in the mid teens. that's because we have a more north—easterly flow to take us through monday and indeed into tuesday. low pressure to the south, high pressure to the north but what will happen compared with monday, on tuesday will start to drag in this slot of dry airfrom scandinavia. so after loss of cloud across north and eastern scotland on monday, and a lot more sunshine on tuesday. even if the breeze will be a slightly cooler one.

that sunshine also breaking through the cloud in the rest of scotland, northern ireland, northern england, wales, the midlands, maybe even east anglia as we go through the day. a few isolated showers out towards the west and temperatures generally mid to high teens, low 20s. not as hot as it was last week. that's the general story for the week ahead, but very pleasant when the sunshine is out. some good, sunny spells to take us through the week but an increasing risk of one or showers here and there too. bye for now. good afternoon. the home secretary, sajid javid, has said it may be time to raise the migration cap on skilled workers, allowed to enter the uk, as part of an overall review of the government's immigration policy as we prepare to leave the eu. businesses and parts of the public sector such as the nhs have been arguing they're struggling to recruit enough skilled workers.
