south—east england. elsewhere affirmative cloud round. wetter later in the evening across northern ireland over night, rain spreading northwards across scotland and parts of wales and western england. quite muqqy of wales and western england. quite muggy where it has been hot overnight across the south—east of the uk but everywhere will have a mild night to come. breeze picking up mild night to come. breeze picking up three sunday. we start with cloud and outbreaks of rain and showers towards the north and west. this area of showers moves further east during the day. it weakens as it moves east. the breeze continues to pick up particularly close to low pressure towards the north—west of the uk and it turns quite blustery here. sunny spells and some heavy showers. a big range of temperatures to end the weekend. most of us in the teens but still ahead of the weather front in east anglia some spots into the upper 20s.
hello, this is bbc news with geeta guru—murthy. the headlines: ahead of his state visit to the uk, president trump defies diplomatic norms, praising borisjohnson and his bid to become prime minister. in madrid, fans gear up for this evening's all—english champions league final — liverpool versus tottenham. the former arsenal and spain player, jose antonio reyes, has died in a car crash at the age of 35. good news for tenants in england, as a ban on letting fees — including credit checks and viewings — comes into effect. now on bbc news it's time for click.
this week — mud, mud, glorious mud! smart matchboxes. and what happens when you get to see for the first time in years? the sun is finally out in the uk and festival season is upon us. and to celebrate the good weather we find ourselves at the world —famous hay literary festival. nestled in the border of england and wales hay—on—wye has been home to the event for over 30 years. i love the hay festival. you can come here and fill your brains with all sorts of new knowledge on all sorts of subjects delivered by all kinds of brilliant speakers.
and when you have done that, you can come see us doing our live show too. yes, once more click live hit the hay. we spoke about robots, explained in detail about how our brains develop and we built an artificial intelligence using matchboxes. please welcome maisy mcadam and willow. applause. but possibly the most magical moment of all of our click live shows starred maisy and her dog willow. about six years ago at the age of 16, maisy was diagnosed with a brain tumour. over the next few months her vision was reduced to a tiny blurry circle in just her right eye. so if you want to pop those onto maisy now... well, maisy had agreed to try on stage the latest version of these givevision goggles. they use magnifiers and augmented reality to amplify the wearer's remaining vision and
highlight outlines. maisy, are they working? yes! i can see your microphone and i can see that you are smiling and i can see the buttons on your shirt. take a look at the audience. yes. they are waving! i can see there is a lady in the front with a red jacket and the guy next to her is wearing stripes. oh, my god, it is so amazing! i didn't quite realise how many people were there and then i them on and i could see everybody in the audience. it was a scary feeling, actually. something maisy felt especially robbed of through this traumatic experience was her ability to read herfavourite books. we have a copy of harry potter and the philosopher's stone here. do you think you would be able to read us the first few sentences if i hold the microphone up? 0k. can you see it?
yes. she cries. i'm sorry. 0k. "mr and mrs dursley of number 4 privet drive were proud to say that they were perfectly normal, thank you very much." it made me really happy that i could have that back, that thing that was taken away from me, to have it back was lovely. i really do miss the sensation of purchasing a book, bringing it home and reading a book and to think in the future that this kind of technology may be mainstream and that ability will be back for me, it is a wonderful feeling. it has been an overwhelming experience, but a really great one as well and i am really grateful. this really was an emotional moment for all of us. but what about other types of vision impairment?
jen copestake has been looking at a piece of technology aimed at people who are colourblind. but does it work? it looks so different! i'm notjoking. it looks so different. that's the real world. that's how we see colour. this was the moment nine—year—old sebastian tried his enchroma glasses for the first time. designed to help improve the sight of people with certain colour deficiencies, his video was similar to many others posted online. there are so many different greens! oh, my god, sweetie. some of these videos have millions of views on youtube. your bag! and a quick internet search sets up dozens of fundraising pages set up by families trying to raise money to purchase a pair. this could be because the glasses are not cheap. they start at $319 us for adults and $269 for children, with similar prices in the uk.
sebastian's father chris first heard about the glasses through watching a video and was keen for his son to try them out. i think you feel, as with all disabilities for children, powerless and very keen to try and do anything you can to improve or correct even partially that disability. sebastian was born with a genetic colour deficiency called protanomalous dichromacy. this gives people a decreased sensitivity to red light in particular. people with this deficiency are often called red—green colourblind. about 8% of men and 0.5% of women worldwide have a degree of colour deficiency in their sight. i met sebastien and his father at the institute of ophthalmology at university college in london. i have this book here. what colour do you see this as? i think it is red but i know it is pink. i find that fascinating. put your glasses on and tell me what it looks like. now i see it as definitely pink.
if you take the glasses off again, we've got quite a few balloons here. what colour is this balloon? i see it as green but i know it is orange. wow. and with the glasses on? now ijust see it as orange. the glasses are said to work using spectral notch filters that actually remove part of the colour spectrum. professor andrew stockman is going to run through some traditional colour deficiency tests with sebastian. these are called ishihara tests, and they're tests for colour deficiency. this test you can definitely see, most people can see, all the colours. what number do you see? a 12. the ishihara test works by showing a number that is slightly different colour to the dots in the background. the glasses don't seem to be helping sebastian with this test. do you see any numbers here? no. and how about here?
any numbers? no? don't worry. i think it's... a10? 0k. and does that change when you wear the glasses? i slightly think it's a 20? that is closer. it slightly improves your discrimination but you would still not pass a colour test. i'm sorry. there are better results with this test which looks at different colours of wool. this one changes so much. it changes from a green to a very standard pink. and this one where sebastian said he saw a shape he could not see without the glasses. i see a pink circle and a pink triangle on a grey background. what do you see? i sawjust a blue circle but when i put the glasses on i saw a triangle here.
so before did you not see a triangle? no. what is going on? we are removing part of the colour spectrum. it changes the apparent colour of light. more than a placebo effect? oh, yes. it definitely changes the appearance of coloured lights. i spoke to the company's president via skype from california who said that the glasses are only sold as an optical assistive device. it is important to understand that the glasses are not a cure for colourblindness. they should help the person to see colour in many situations but they don't necessarily provide normal colour vision. recent peer—reviewed research from the university of grenada conducted on 48 people with colour deficiency concluded that the enchroma glasses introduce a variation of perceived colour but do not improve results in diagnostic test for colour deficiency or give the wearers normal colour vision. enchroma provided a sustainment regarding the study saying only its indoor use glasses were used on two tests with the subjects wearing glasses
for a few minutes at a time. they said this would tend to minimise any results. for chris, the science behind the glasses is less important than the experience his son gets while wearing them. if i thought that him wearing the glasses was harmful then i would be more concerned. if it is a parlour trick, to be brutally honest, i don't really care. but others may expect more definitive results, especially considering the marketing hype and luxury pricetag. hello and welcome to the weekend in teck. it was the week that huawei founder ren zhengfei said he would the first protest if china banned apple. the chinese company is seeking to overturn its own us ban. mark zuckerberg has been feeling the heat in europe. facebook, whatsapp and instagram were outed as the most investigated companies by ireland's data privacy watchdog.
the commission says 11 out of 19 of its probes were targeted at the trio. in better news, british scam victims conned out of money online are now more likely to get the cash back. eight banks including barclays, rbs and lloyds have promised better protections for customers which should mean more refunds. this pokeball is notjust for collecting pokemon. it could help you catch up on your sleep as well. the bluetooth tracker lets player zone ingame rewards for sleeping well. roblox is one of the most successful multiplayer games targeted at children, but there are fears it is being used for grooming. its creator says it has strict filters in place to stop inappropriate behaviour and blame any misuse on third party apps not affiliated with the company. and finally, the world's first raspberry picking robot is set to work on a british farm. it may be slow now but fieldwork robotics says its bot should soon be able to pick about 25,000 berries a day, nearly double
what a human can pick. not bad, given how delicate these tiny fruit are. fingers crossed that things do not go pear—shaped. our phone cameras have been getting better and better over the years with all of the big players constantly trying to outdo each other. but now, some of the chinese phone manufacturers seem to be leading the way with features like 5x optical zoom. i'm putting some of the latest devices to the test, with a spot of help. nick turpin has spent 20 years as a leading street photographer, working in london and new york. so he knows a thing or two about cameras. hello. good to meet you. nice to meet you as well. firstly, the 0neplus 7 pro. the statistics are impressive
plus a few nice touches. no punchhole, no notch so when i press the selfie camera, it needs to come from somewhere. look at that! it comes out the top. if your phone thinks it is being dropped, this happens, it goes back in. anyway, easy to be distracted by that. what we actually want to do is test three different focal lengths to start with and you are the person to do that. this is a 1—to—1 ratio where we get exactly what we see. as soon as we zoom into the city and we lose a little sharpness, a little loss of accutance. zoomed out it makes a respectable landscape photograph. and if we go into ten times zoom, it is quite shaky so you really need to almost stop breathing. the phone has a 3x optical zoom and beyond that it is starting to do it digitally so i suppose we expect some loss in quality after that three times? as soon as you move from optical to digital zoom, you enlarge the information you already have
so you lose sharpness and detail. and the 10x zoom... it could be sharper but we managed to get all of the windows and all the cranes. really quite good detail there for a 10x zoom on a smartphone. next up, the 0ppo reno sg. so much more detail. it looks a little over sharpened, i think there is some processing going on. but there is good detail in the windows of the buildings there. i think it has done a slightly better job. and the 10x? you can see individual church towers and trees, cranes, every single window in every single building. and from the controversial huawei comes their offering, the p30 pro. the volume buttons are on the wrong side for taking pictures. so when you hold it horizontally there is no clicker here. is it for left—handed people? much betterfor them. i don't think the image looks quite as nice as the previous phone but we still have good detail in the sky and the shadows
and that is something i look for. this is the 10x zoom. it looks more natural. i think it is probably the nicest of the three that we have seen. but it also has a 50x zoom. amazing. is it humanly possible to be still enough? that's so zoomed in i can see a single tower block on the screen so i will try... it is difficult to use. you almost need a tripod — which defeats the object of having a mobile telephone. a 50x zoom is impressive, i'm not sure the image is usable for a great deal. we also tested them in portrait mode. the 0neplus, tonally this is very nice, it is not too contrasty, the colour balance looks good. 0n the 0ppo in the middle, the colour balance doesn't look so good, this looks very cold and blue. i don't think the camera has judged the light so well. and the huawei? this one i think looks a little over—processed and oversatu rated. and the contrast is so high —
see how dark your face is there? as a nonprofessional, i actually quite like that look. i suppose they look like they have been edited a bit. yeah. i think a natural picture like this has good skin tones and so on. the more contrasty one would probably look better posted on instagram or social media, whereas this one would make a better print. the screens on the 0ppo and huawei were easier to see in the sun than that on the 0neplus, but all the phones also feature modes for dealing with low light. nick was pretty wowed by what a smartphone camera can now achieve, but what was his overall verdict? i think i was incredibly impressed by the 0ppo, as a professional photographer i thought it had a really nice blend of good tonality, it wasn't too contrasty, wasn't too processed, it had good detail and sharpness. i think the huawei did look a little bit digital, some of the colours looked a little unnatural, and i think the 0neplus was my least favourite.
0k, more flowers now. and these beautiful tulips were generated by a computer programme. the realism is uncanny, and that is because the algorithm that generated them was trained on 10,000 pictures of real tulips. anna ridler, the artist behind this work, then hand—annotated each picture. for each photograph i wrote what colour it was, how stripy it was, what type of tulip it was, what state it was in, so if it was a bud or if it was dead, and i used that information to then use machine learning to train an algorithm to produce these moving image pieces. i had read about tulip mania which was this in dutch history in the 1630s when the price of a tulip went at one point for the same price as an amsterdam townhouse, and it was the first known speculative bubble.
and i was interested in kind of comparing this moment in history with speculation that is going on now around cryptocurrencies. so in this piece the tulips are kind ofjittering and flickering, that is because the way the tulips have been created by the algorithm is controlled by the price of bitcoin. so as the tulips change, that is because the price of bitcoin is changing. as beautiful as these tulips are, every so often the realism falls away, and you start to see the artifice. part of the reason that i display my dataset as a separate work is to really kind of emphasise the humanity and humanness that sits behind all of these processes. so here the machine learned what a tulip looks like at each stage of its life cycle. but machine learning is used in lots of different ways. it already helps doctors to care for their patients, bankers to... "care" for their clients‘ money, and is used by our voice assistance to care for our needs...
alexa, living room, evening, on. ..kind of. but even though machine learning applications are becoming more infused into our daily lives, most of us know very little about how it all actually works. until now. because at click live at hay, we showed our audience how a machine can learn to play noughts and crosses. it is a machine called menace, and it is made of matchboxes. there are 30a different combinations of noughts and crosses that you can have in a game of noughts and crosses. over here are 30a different matchboxes — each one corresponds to one of those combinations. so when the game gets to a certain state, you look through the matchboxes here and find the one that matches that permutation of noughts and crosses, give it a shake, and pull out a bead at random.
now i have pulled out a pink bead, which means that menace plays its next move there. at the start of the day the boxes contained the same number of beads of each colour. every time menace won, it was rewarded with more of the right colour beads. when it made a mistake, those beads were taken away. to start with, menace‘s moves were entirely random, causing it to lose most of the time. but as the day progressed, those bead colours started to shift to match the best moves that menace could make in any one position. after about 70 games, menace could force a draw almost every time, which in noughts and crosses is pretty much the best you can hope for. i drew against matchboxes, yay! this random trial and error method with so—called reinforcement learning is exactly how machines learn. it is usually done at incredible speed, playing millions
and millions of iterations. now machine learning, so say its advocates, may one day solve the world's most pressing problems, from climate change to finding cures for deadly diseases. but some think it may bring about the end of the world. well, it certainly seems the end of the world is something that the games industry has been obsessed with for a while. marc cieslak has been playing yet another title set after the apocalypse. rage 2 is a first—person shooting and driving game set in an explorable post—apocalyptic open world, a landscape populated with mutants, cyborgs and mohawked bad boys and girls out for blood. sound familiar? loads of games this year have a similar set up. and in an effort to find a new way to talk about a title like this, i'm going to have to take radical steps. we scoured the globe in search
of a location which could match the harsh desolation of a post—apocalyptic landscape. our search brought us here: suffolk, in the rain. in rage 2, the player assumes the role of a ranger, one of the last remaining symbols of order in a world devastated by a giant asteroid strike. developed by avalance studios teaming up with id software of doom and quake fame, it is also not entirely serious, looking at playing like a shouty, day—glo version of the end of the world. it is silly and a bit gross. the closest thing we could find to tearing across the wasteland is banger racing. here we have specially adapted vehicles with sturdy safety cages fitted, which is handy. rage 2 is a fairly daft game, so this seems like a fairly daft way to review it. this is my chariot. definitely doesn't come
with parking sensors. as the bangers line up ready to race, it gives me time to reflect on the driving aspects of the game. to get from mission to mission and to explore the wasteland, the player is initially equipped with a phoenix off—roader, which offers a good mix of weapons and versatility. my stripped out supermini is positively pedestrian in comparison. there are different vehicles scattered across the giant game map, an open world that is perhaps a little too open — there's often lots of travelling with very little going on. thankfully the mudfield track i have to drive around here is a lot smaller than the explorable world of the game. as the name suggests, rage 2 is not a super chill, relaxing video game. it is all about racing off—road vehicles across a post— apocalyptic wasteland, and shooting stuff, with a wide variety of weird exotic weapons. when running around first person, those weird weapons are the core
part of the title, allowing players to dispatch enemies in increasingly over—the—top, and not safe for tv ways. what isn't nice is because i don't have a windscreen or windows, all of this mud, when someone drives past you, ends up in your mouth. yep, lot of mud in the mouth again. cheers for that. of course, driving in conditions like this can only end one way. hoho! ultimately, rage 2 is a bit like hurtling around this muddy track at breakneck speed. great fun when you are doing it, but not an experience that stimulates the grey matter all that much. that was marc, and it may not be the end of the world as we know it, but it is the end of the show from hay. thank you so much for coming on for the ride, and if you need us during the week we live
on all the usual places, facebook, instagram, youtube and twitter at @bbcclick. thanks for watching, we will see you soon. the uk recorded the highest temperature of the year so far today. in east anglia and the south—east of england where it will remain very warm tomorrow. the air coming up from quite a long way south of the uk, it has been a hot one in madrid, that big soccer game taking place this evening. it has not been as hot as it was in madrid but temperatures have soared for some today but you have to have been to the south of this weather front
to the south of this weather front to have a warm day. along the weather front and north of it there has been plenty of cloud around, bit of rain in places two and there is some heavy rain on the way tonight. and in the day with plenty of sunshine towards east anglia and the south—east of england, a warm, muggy night to come. wetter over northern ireland tonight, rain into northern scotla nd ireland tonight, rain into northern scotland and wales and western parts of england as well. and while night where ever you are but particularly warm and muggy where we had seen the highest temperatures of the day. into pa rt highest temperatures of the day. into part two of the weekend, low pressure is close by, this is going to feed this cold front eastwards during the day so there is cooler air following on during the day so there is cooler airfollowing on behind, it only moves airfollowing on behind, it only m oves very airfollowing on behind, it only moves very slowly eastwards and it may well be weakening as it does so. still quite vigorous to start the day so plenty of showers along it, some outbreaks of rain, into scotland, dry in northern ireland at least to start the day. showers replacing the sunshine across the east of england with more cloud and
the chance of a light shower. a breezy day where ever you are, quite blustery towards north—western parts, feeding in some showers, may bea parts, feeding in some showers, may be a few heavy ones, but also sums son as well. ahead of the weather front and in the sunshine in east anglia, expecting temperatures in a few spots still to peek into the upper 20s before it turns cooler on monday. looking at monday, low pressure nestled to the north of scotla nd pressure nestled to the north of scotland and low pressure is in charge for much of the week ahead, starting quite breezy, the wind is easing, plenty of showers developing, particularly into tuesday. light went so slow—moving heavy downpours as well. temperatures close to a little below average for the time of year but at least the chance of seeing a little bit of useful rain on some of the gardens.
this is bbc news. i'm geeta guru—murthy. the headlines at four: ahead of his state visit to the uk, president trump defies protocol, he praises borisjohnson and his bid to become prime minister. i've always liked him. i don't know whether he's going to be chosen, but i think he's a very good guy, a very talented person. in madrid, fans gear up for this evening's all—english champions league final — liverpool versus tottenham. here in the spanish capital with four hours to go until kick—off, the temperatures are rising, so are the passions here in madrid. the former arsenal and spain player jose antonio reyes has died in a car
