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 at 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
3:32 am
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 on to 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? yeah!
3:33 am
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. yeah. 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! applause. i didn't quite realise how many people were there and then i put 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." applause. 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 quite mainstream and that ability will be back for me, it is a wonderfulfeeling. it has been a very overwhelming experience, but a really great one as well, 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!
3:35 am
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 us$349 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.
3:36 am
i think you probably 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?
3:37 am
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 example 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.
3:38 am
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
3:39 am
colour of light. and it's 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.
3:40 am
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. yes, of course, if i thought that him wearing the glasses was harmful then i would be far 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. 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
3:41 am
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
3:42 am
behind all of these processes. and that is it for the shortcut of click from hay, the full—length version has so much more from this amazing festival. you will find it on iplayer right now, and if you need us during the week we are on social media, youtube, instagram, facebook and twitter. thank you for watching and we will see you soon.
3:43 am
hello and welcome to newswatch with me, samira ahmed. remain parties did well in the eu elections but did bbc news coverage make too much of that, underplaying the success of brexit party? others have complained and the success of nigel‘s new party new party received too much attention on election night. it was the eu vote that was never meant to happen here. but when the results came in on sunday evening, the bbc election night machine swung into action.
3:44 am
over the next few hours, there was plenty of analysis and interpretation of the results. at a quarter past one in the morning, huw edwards asked laura kuenssberg where she thought things stood. laura, so far, what are our headline thoughts? brexit party the clear winners. maximising the inheritance they got from ukip. they have been outperforming ukip in these elections. really squeezing the tories. terrible result for them as a governing party. in fifth right now. no doubt about the big losers on the night, but the emphasis on the brexit party as the clear winners annoyed some of their opponents. susan thought there was another fairer way of looking at the outcome. and recorded this video of her thoughts when watching on monday morning. four parties were leading with a pro—eu anti—brexit message.
3:45 am
the lib dems, the greens, plaid cymru, change uk, these parties secured at this point in time 38% of the vote and their vote share went up. it is a shame they didn't have a formal remain alliance as they discussed and maybe you could have reported it better but it's still obvious. the brexiteers, nigel‘s brexit party and his old ukip party got 36.8% of the vote. they got a bit less of the total vote. i know that brexit got meps, but you could've highlighted the strong remain vote more clearly. you didn't cover the lib dem and green party successes nearly enough this morning. the aggregate vote won by the remaining supporting parties may not have been given enough priority for some viewers, but it was covered on bbc news, including in this report from tom barton. it wasn'tjust a good night for the brexit party. those standing on a clear remain platform also made a great leap forward.
