now on bbc news, time for click. this week: contact tracing. home schooling. finding love in quarantine. and would you believe— remote weddings. welcome to click. the days are getting longer and so is the how, but we are still here. hope you are 0k, lara is in the house, well hers. -- hair. good to see you, what have you been doing apart from growing your hair? i have been watching a

lot of tv, we are big fans of doctor who here, so on social media thousands of people agree to hit play on the same episode at the same time, like seven o'clock. and what then happens is we all watch together but the direct, the scriptwriter and some of the actors are all tweeting along while we are watching, so you get this kind of live director's commentary on a second screen. i love it, it is a communalfield, second screen. i love it, it is a communal field, we are watching these great programmes. that sounds really fu n. these great programmes. that sounds really fun. in this house we have been very busy making television. downstairs my husband had been making his tv show, it is a good job iam good making his tv show, it is a good job i am good with jack because he has needed some help. yes, i have seen. —— with tech. this site has become controversial, because when his side arrives for his show, it is huge. —— sign. so next week this may have to move closer to the camera. brilliant plan. if it keeps you safe during lockdown, you guys carry on with the war of logos. we are still in

lockdown here in the uk but now questions are starting to turn to when and how lockdown may be eased. 0ne when and how lockdown may be eased. one of the key conditions seems to be when we can accurately test for covid—i9, and trace the people who have had it and who they have been in contact with. now as we have been hearing governments around the world are pinning their hopes on our phones, and so—called "contact tracing apps. they sound great tingle — but can they work? here is chris fox. —— they sound great— but can they work. contact tracing is about who you have been around, so if you have been ill you can be quickly warned about whether they have passed on an infection. but once out of lockdown we can't imagine every person we have been close to, whether that is in a park oi’ close to, whether that is in a park ora close to, whether that is in a park or a trainer at close to, whether that is in a park ora trainerata close to, whether that is in a park or a trainer at a party. in time is critical. what if one of these people later find out they have covid—i9 and that they might have given it to me? so governments

around the world are proposing we use our phones to track who we meet, and critically, send instant cascades of alerts if someone test positive. so we can quickly go back and self isolation and stop the spread. several ideas about how this could work had been put forward. 0ne way is to use gps satellite location data to keep a record of everywhere you go. then if you get ill, the system you go. then if you get ill, the syste m ca n you go. then if you get ill, the system can warn people who have been nearby. but it goes without saying that asking people to keep a record of everywhere they have been and share that with a third party or government raises privacy concerns and satellite location data doesn't work well indoors, or underground. and it can't tell you what floor of the building you are on, so no good for people who live in flat. mobile phone towers can be used to work out roughly where you have been as your phonejumps roughly where you have been as your phone jumps from tower to tower as you move around. but while this works on any phone without installing any apps, it is far less accurate than satellite location

data so it is not usually useful contact tracing. although it can be used to check people are staying at home during a national lockdown. 0ne idea that is gathering attention is using bluetooth or smartphone. this is the option being explored by the uk's nhs x team amongst others. the idea is that anywhere you go my smartphone will extend an honest key with other smartphones nearby using bluetooth. my phone would keep the keys it receives for 14 days as strangers will keep mine. if i don't get ill i will be able to declare my status and up and add mikey to a central database. that status and up and add mikey to a central data base. that means everybody who has picked up my key while out and about and be warned insta ntly that while out and about and be warned instantly that someone they have met has coronavirus. this idea has the backing of apple and google, they plan to build the tech into their mobile operating systems, i0s and android, so in future it won't even use a third—party app for it to work. using bluetooth offers more privacy, because the codes shared

are anonymous, the matching can be done on your device rather than on a central database, done on your device rather than on a central data base, and the done on your device rather than on a central database, and the system doesn't use any location data so it won't keep a record of where you have been. but you will need a smart phone, not all of them have the right kind of bluetooth for it to work. on the other hand, if you collect location data and store it centrally, then governments and health researchers can analyse the data, identify virus hotspots and track where the virus is spreading. either way, for any system like this to work it needs a big proportion of smartphone users to take part. if too few people take part the system isa too few people take part the system is a lot less useful. that was chris. as it happens this week we saw the first glimpses of the uk's bluetooth base contact tracing up being trialed at a royal air force base in north yorkshire. but hundreds of privacy and security experts from around the world have written an open letter expressing concerns about the way they think that contact tracing apps need to

pay attention to our privacy. 0ne that contact tracing apps need to pay attention to our privacy. one of those experts is online now, professor alan woodward. we have talked about three different ways of tracking people's location. do you think any of them are accurate enough? the short answer is no. none of them are because in the real world, ina of them are because in the real world, in a perfect world, if you are in the lavatory you might get something like the accuracy you need. but in the real world, none of them are. going to be accurate enough, particular indoors, but really bluetooth is the only option you have. but that is why you can't rely solely on the distance data. and why the better apps are going to model in time as well. so for example suppose you come within two metres of someone example suppose you come within two metres of someone passing them on a bike ona metres of someone passing them on a bike on a road, but actually you only get one ping from the bluetooth beacon that is sent out. it is not necessarily a risk. 0r

beacon that is sent out. it is not necessarily a risk. or it is a much lower risk than if you are cycling together for lower risk than if you are cycling togetherfor an lower risk than if you are cycling together for an hour. do you think there is a danger that we are putting too much emphasis on the technology and the contact tracing apps? you can'tjust rely on technology on its own to automate everything. they will have to be a human in the loop. and there is also an element of, we know that the ultimate solution is only going to come when we have got a vaccine and proper testing for this. that is universally available, and available at scale. so there is a bit of what my colleague called" do something itis". with this, it makes people feel better because the government is doing something. we must not get carried away with the fact that this is the end solution. it might be pa rt is the end solution. it might be part of the solution but is not com plete part of the solution but is not complete solution. hello and welcome to the weekend tech. it was the week that netflix added 16 million new

subscribers to the first quarter of the year. nintendo said it is increasing back switch production by 10% and facebook released its gaming out ahead of schedule. a move they said was directly in response to the lockdown. facebook also introduced a coronavirus survey in the uk this week asking select if they had had symptoms of covid—i9. it is a part ofa symptoms of covid—i9. it is a part of a joint effort with carnegie mellon university to track the unit —— illness. this joins mellon university to track the unit —— illness. thisjoins an online heat map to track where people in america are filling your county by county. people can report any covid—i9 of flulike symptoms they had had in the past 2a hours. a device made from a raspberry pi minicomputer is being used to remotely monitor vital signs in coronavirus patients. engineers intro designed the device which attaches to a fingerprint probe. it uses “— attaches to a fingerprint probe. it uses —— feed patient data back to nurses via wi—fi. 60 motor lights we re nurses via wi—fi. 60 motor lights were launched into orbit by ellen

normal circumstances we would never let our children look at a screen for this long everyday. interactions with friends, school classes and of course the context of it does make a difference, but my seven—year—old asked me "mummy am i having too much screen asked me "mummy am i having too much screen time?". wow, she is asking although i expect actually that means mummyi although i expect actually that means mummy i think i have had enough school on screen for today. 0k, enough school on screen for today. ok, maybe, i haven't thought about that. let's talk dating. rather surprisingly through this period of isolation, dating apps have had more interactions on than before. now i have heard this too and i thought this was quite weird because... why would you try and start the dating process now when you can't go ahead and immediately meet someone in the flesh ? and immediately meet someone in the flesh? i don't get it, i am not single so maybe i am not thinking on the right way. but i found it weird as well. that was my first thought but i suppose on the other hand, if you are looking for love, you might as well get on the case. in every way, this is the story of

just another indian wedding. there's a bride and a groom. an online matchmaking service with millions of users across the world has seized the opportunity and introduced a feature called wfh. no, it's not work from home, it's wedding from home, and even the lockdown couldn't stop some of the 200 guests from dancing at this virtual hindu ceremony in india. and across the globe in california, one determined couple used zoom who hosted their virtual ceremony, but there were always going to be some technical issues. by the powers invested in me by the internet, i now pronounce you partners in life. weed open to the zoom call early to, like, testings, make sure people

could come in early if they wanted and hang out, and because of that we hit the a0 minute mark before we we re eve n hit the a0 minute mark before we were even ready. speaking my vows to christianity watching her tear up and then! christianity watching her tear up and then i tear up and i look and in the video call, in these little boxes on the screen, people are tearing up, but it's like a screen and this is our modern world now. but it was still, like, very intimate. yeah, that's true. but how about the big players? the dating app industry is worth billions but is built on facilitating face—to—face meet ups, so many would expect that the lockdown would mean a drop in usage, however industry leader tender told us on the 29th of march, there were 3 billion swipes globally, which is more than on any other day in the history of the app.

and rival rumble told us they've seen a and rival rumble told us they've seen a significant increase in messaging and video calls since late march. we caught up withjustin mcleod, the ceo of hinge, another major dating app to get an insight into the changing habits of users. so we are seeing about a 30% spike in messages. people are matching more and they're having a lot more conversations, and they're turning those conversations into video chats and phone calls. and even more interestingly, we are seeing about 90% of our users going on video calls saying they really enjoyed the experience and will do it again. it's definitely not as awkward as people fear it's going to be. i do think the culture of dating will change the result of this. one of the most important things is people are getting used to video chatting and they‘ re people are getting used to video chatting and they're dipping their toe in and realising it's pretty great, and i think people will

continue to do that after social distancing ends. i definitely think it's something people will continue to do. so, the big dating apps have found that for their users, lockdown hasn't proved that much of a barrier in looking for love, but there are some other creative solutions starting to spring up, and 0mar metap has been putting one of them to the test. with dating apps exploding in popularity over the past years, a generation learned a new way of finding love? now with social isolation in place, the dating game isolation in place, the dating game is being reinvented once again. also innovating our two roommates from new york, they are... they've come up with love is quarantine, a dating format broadcast as sort of a live reality show on instagram. after giving a view details on their

google sheets, six people are randomly sorted into pandemic pods and paired up to go on phone dates with each other. i'm actually going to give this a go myself, and even though it's a phone date, i do have to look my best, so i'm going to get ready. as the evening goes on, i have to send a video to love is quarantine after each date telling them how it went, so the audience on instagram watching this reality show u nfold instagram watching this reality show unfold can keep up with the action. for the purposes of this online show, i have to provide a short intro video. hey there, my name is 0marmetap, i'm 29... during the round robin date, those involved don't know what each other looks like. in all the videos uploaded, fingers obscure faces. 0nly uploaded, fingers obscure faces. only if the couple hits it off are they finally revealed. creators wa nted they finally revealed. creators wanted to get away from the image

obsessed focus of websites and what is said is important. personally i have a common form of dwarfism. a lot of girls, not all, are looking for the six foot four attractive... he's got the beard and the good hair and the muscles and all the things, so and the muscles and all the things, so for me to go on a dating app like hinge or tender, the numbers aren't great because i don't get the opportunity to swipe left, but for love is blind and love is quarantine, we are allowing people the opportunity to love people and who knows? right, it's 2am here, making it evening time in the us, and before the first date is even begun, excitement is building up. so, must admit, bit nervous. let's see how this goes. and as i'm talking away, i realise that there is little to worry about. largely in

pa rt is little to worry about. largely in part because i'm not focusing on anything except the conversation. 0k, i'vejust anything except the conversation. 0k, i've just had anything except the conversation. 0k, i'vejust had my first anything except the conversation. 0k, i've just had my first date and it kind of feels like a 90s where if you had a penpal via letter or e—mail, you wouldn't see them until you actually met them in real life but it's refreshing for a social media generation. right now i'm about to send a video talking about the date and how it went for eve ryo ne the date and how it went for everyone to. we are excited so keep us everyone to. we are excited so keep us posted. we believe in love! but after this lockdown is over, will there still be a place for love is quarantine? for others who consistently use dating apps, love is quarantine is a better option, it's a lot more of an intentional approach. it is hard because i know that when i am using an app i have all this information about somebody, what they like, i no i can't be more particular about it. i was may more

nervous on love is particular about it. i was may more nervous on love is quarantine than in person because i get scared of what i'm going to say, but when they're in person there is a connection and there's more back and forth. for better or worse, when dating apps came in, they changed our culture. in this time of isolation, still relying on technology, but relearning how to connect with people, so maybe the art conversation isn't dead after all. 0h, conversation isn't dead after all. oh, what conversation isn't dead after all. 0h, whata conversation isn't dead after all. oh, what a lovely, lovely piece of tv that was. that was 0mar, he's online now and before we go any further, nate, can we have look at 0mar again when he's dressed up all posh? there. can i say, posh clothes from the waist up but you're still wearing your shorts, what's going on?” but you're still wearing your shorts, what's going on? i decided to go smart casual, so smart on top and casual on bottom, as per usual! brilliant!

that's brilliant! this did seem to be as much reality tv as it was a dating app. did you actually feel like you were on real dates?|j really like you were on real dates?” really did, more so than i would if i was on really did, more so than i would if iwas ona really did, more so than i would if i was on a real dating app, normally it is full of pictures and your swiping depending on how someone looks, but here you're forced into a conversation for 30 minutes to an hour to really get used to the person as you really word on a date. many people are, in all honesty, quite bothered about looks, aren't they? they are, and that's why this is stripping all that back and focusing it on all personality, so the person you could be dating in the person you could be dating in the future, you're really getting to know them and whether there compatible with you. listen, 0mar, thanks for doing it, what a great sport and ladies, you would date this man, wouldn't you? you would absolutely date this man! i'm nodding, i'm not single, but yes, 0mar is lovely! i'm nodding, i'm not single, but yes, omar is lovely! i'm afraid

that's it for this week, thank you so that's it for this week, thank you so much for and sticking with us once again. as ever, you can keep track on what the team is up to, albeit from home, throughout the week on youtube, instagram, facebook and twitter — @bbcclick. thanks for watching and we'll see you soon. though bye—bye. hello there. after a another predominantly dry week for most parts of the uk, the weekend promises plenty more dry weather. but slow, subtle changes, the increasing chance of catching a shower and it will begin to feel cooler particularly across northern areas. nothing much is changing very quickly at the moment because the pressure pattern is very slack. not many white lines at all on this chart. not many isobars.

that means the winds are very, very light. there's nothing really to push the weather along. we start off the day with a lot of cloud across eastern scotland and eastern side of england and misty and murky conditions in place. that should tend to break up, the mist and fog should lift and all of us should get to see some spells of sunshine. perhaps a bit more cloud than we had over the last couple of days. temperature—wise, 17 to 21 degrees. a bit coolerfor some northern and eastern coasts. north coast of northern ireland having a cooler day and as we go into the late afternoon in the evening, wales and the south—west could see a shower, and the early hours of sunday, generally more cloud rolling in across the north of scotland. those are your overnight temperatures. most places above freezing. it will be a little bit chilly across some eastern parts of england. we go to sunday and this area of low pressure, quite a weak affair, starts to move its way in from the north, that does increase the chance of seeing

some showers across northern parts of scotland, a frontal system pushing south and a band of cloud and some showery rain possible with that and ahead of it across the heart of england and wales, we could see the odd hefty shower into the afternoon. there will still be a lot of dry weather and sunshine and another warm day down towards the south, but noticably cooler across the northern half of the country. and into monday, you see the colder air making some inroads southwards, so lower temperatures for most parts on monday. a band of cloud and frontal system sitting around parts of england and wales and maybe the odd splash of rain but we could see slightly more significant wet weather developing down to the south later in the day. 21 degrees in london, but the further north you are, the much cooler feel to the weather. and for all of us, it is going to turn cooler as we head deeper into next week. and there is the increasing chance of some rain and some fairly brisk winds as well. that's all from me for now.

this is bbc news, i'm simon pusey. our top stories: 0fficials confirm 50,000 people have now died in the united states. meanwhile, president trump attacks the media after he suggested using disinfectants in a treatment. i was asking a sarcastic and a very sarcastic question, to the reporters in the room, about disinfectant on the inside. but it does kill it, and it would kill it on the hands. the uk government's new website for tests is swamped and shut down for hours as it's inundated by key workers. world leaders throw their weight behind a drive to develop new treatments for covid—19 and ensure that everyone gets access to them. and the rohingya refugees rescued after being stranded at sea for many weeks —
