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 hair, but we are still here. Hope youre 0k. Look, laras in the house well, hers. Hello, good to see you spencer, how are you . What have you been doing, apart from growing your hair . I have been quite busy watching a lot of tv, actually we are big fans of doctor who here, so on social media thousands of people agree to hit play on the same episode at exactly the same time, like seven oclock. And what then happens is we all watch together but the director, the scriptwriter and some of the actors are all tweeting along while were watching, so you get this kind of live directors commentary on a second screen. I love it, it is a kind of communal feel, we are all watching these great programmes. Oh, that sounds really fun in this house we have been very busy making television. Downstairs my husbands been making his tv show, it is a good job i am good with tech because he has needed some help. Yes, i have seen. This sign has become a bit controversial, because when his sign arrives for his show, it is huge so theres now a bit of competition. Next week this may have to move closer to the camera. 0k, brilliant plan. You do that if it keeps you sane during lockdown, you guys carry on with the war of the logos. Of course we are still in lockdown here in the uk, but now questions are starting to turn to when and how lockdown may be eased. One of the key conditions seems to be whether 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, but can they work . Here is chris fox. Contact tracing is about keeping a record of who you have been around, so if you get ill they can be quickly warned that you may have passed on an infection. But once were out of lockdown we cant possibly remember every person we have been close to for long enough to catch coronavirus whether thats in a park, or on a train or at a party. And time is critical. What if one of these people later finds out they have covid i9 and 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 somebody tests positive so we can quickly go back into self isolation and stop the spread. Several ideas about how this could work have been put forward. One way is to use gps satellite location data to keep a record of everywhere 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 doesnt work well indoors, or underground. And it cant tell you what floor of the building youre on, so no good for people who live in flats. Mobile phone towers can be used to work out 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 its not hugely useful for Contact Tracing. Although it can be used to check people are staying at home during a national lockdown. One idea thats gathering attention is using bluetooth on a smartphone. This is the option being explored by the uks nhs x team amongst others. The idea is that anywhere i go, my smartphone will extend an anonymous key with other smartphones nearby using bluetooth. My phone would keep the keys it receives for 14 days and strangers will keep mine. If i then get ill i will then be able to declare my status and up and add my key to a central database. That means everybody who has picked up my key while out and about can 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 wont even use a Third Party App for it to work. Now 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, and the system doesnt use any location data, so it wont keep a record of where you have been. But youll need a smartphone, and not all of them have the right kind of bluetooth for it to work. 0n 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 is a lot less useful. That was chris. As it happens, this week we saw the first glimpses of the uks bluetooth based Contact Tracing app 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. One of those experts is online now, professor alan woodward. We have talked about three different ways of tracking peoples location. Do you think any of them are Accurate Enough . The short answer is no. None of them are, because in the real world, in a perfect world, if you are in the laboratory you might get Something Like the accuracy you need. But in the real world, none of them are going to be Accurate Enough, particularly indoors, but really bluetooth is the only option you have. But that is why you cant 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, passing them on a bike on a road, but actually you only get one ping from the bluetooth beacon thats sent out. Its not necessarily a risk, or it is a much lower risk, than if you are cycling together for an hour. Do you think theres a danger that were putting too much emphasis on the technology and the Contact Tracing apps . You cant just rely on the technology on its own to automate everything. There 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 one of my colleagues called do something itis. There is an element of we can quickly do something with technology, and with this do something itis, as he calls it, it makes people feel better because they feel the government is doing something. So we must not get carried away with the fact that this is the end solution. It might be part of the solution, but its not the complete solution. Hello and welcome to the week in tech. It was the week that netflix added 16 million new subscribers in the First Quarter of the year. Nintendo said it is increasing switch production by 10 and facebook released its gaming app 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 users if they had had symptoms of covid i9. It is a part of a joint effort with Carnegie Mellon university to help track the illness. The uk surveyjoins an online heat map to track where people in america are feeling ill, 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 tested to remotely monitor vital signs in coronavirus patients. Engineers at the university of toronto designed the device which attaches to a fingertip probe. It feeds patient data back to nurses via wi fi. 60 more satellites were launched into orbit by elon musks Spacex Starlink mission, joining 360 that are already up. Spacex says it will eventually have 12,000 satellite in space with the aim of providing Global Internet coverage. And finally it was the 50th anniversary of earth day this week, with celebrations taking place mainly online. The European Space agency beamed a powerful message of human unity from Stephen Hawking out across the planet. When we see the earth from space we see ourselves as a whole. 0k, school is back and that means for parents at home, we have to start helping our children with their lessons. The bbcs bitesize has had a huge upgrade. Sometimes you have to work it out in your head. It has hundreds of bits of interactive content, following the National Curriculum for both primary and secondary students. Also, theres the oak national academy, which is backed by the government here in the uk, and thats designed by teachers and provides video lessons, worksheets and quizzes related to many subjects. The truth is, there is a lot of homeschooling content online, but its pretty overwhelming for any parent to work out where to go for what. So heres kate russell with a round up of whats around. You know, its ok to admit that this shutdown is sending you a little bit doolally. Like these parents who posted these brilliant memes about homeschooling. And with schools going back but the kids remaining at home, here is my tech survival kit. Many of the resource hubs that teachers already use have put up special sections to guide parents through this stressful period. Twinkle has daily activities for primary age. A search for live lessons brings up tons of pre made classes with qualified teachers. And if your kids teachers are emailing worksheets in a confusing array of file formats, zamzar can quickly convert stuff so you can open them with ease. You are not going to become a first class teacher overnight, so try not to be too hard on yourself. And dont get out too many detentions, itll punish you more than it will them. Parentkind is full of straightforward advice for the shutdown, including what to expect from your kids school and some tips to create a good learning environment for all ages. Lessons aside, keeping the kids focused with all the distractions of home will be tough, so dont be afraid to use the bells and whistles of educational apps to help keep their attention. Sign up to easypeasy for a guide to playful learning, including daily game ideas and tips. You can also track progress to help see the difference you are making. Phonicsplay teaches reading skills using phonics. The parents section can help with understanding the teaching process. This is usually a paid site, but the makers are offering everything for free during the shutdown. Carol vorderman became famous doing quickfire maths on a tv show, and her video classes for kids are now also being enjoyed free of charge for the duration of the shutdown. Good science begins with thinking like a scientist, and thats the focus of this site full of lessons and activities. When youre feeling like it is going to spin out of control, set the kids a brainpop quiz. With fun, colourful videos, theyll forget theyre learning. If you want to dig deeper there are challenges, worksheets and vocabulary tests you can set. And i wouldnt be doing myjob as a tech evangelist if i didnt suggest that now is a really good time to learn coding. Its something you can do together, and teaches logic and problem solving skills too. Raspberry pi projects and codeacademy are two old favourites that have fun, interactive projects for all stages of learning. For primary age, bee bot is a fun app that teaches the principles of coding and develops computational thinking in a playful way. And if all else fails, restore peace and tranquility with some mindful meditation cookie monster style. Head over to the sesame street channel on youtube kids where they will be publishing two new monster meditation cartoons each week, to help younger kids deal with the stress of having you teaching them at home. Me smell with me little nose, cookies oh boy oh boy oh boy that was kate, and i have to say to all the parents trying to juggle a job and be teacher now, hats off to you its a really tough job and i am sure you are doing an absolutely brilliant job. That includes lara, i mean, you are doing this job and trying to be teacher at the same time, its gotta be hard. Well, homeschooling is actually going quite well, but like a lot of parents i expect, i keep asking myself, is my daughter having too much screen time . Because under normal circumstances we would never let our children look at a screen for this long every day. Yeah, thats true. 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 time . Wow, she is asking . Although i suspect actually that means, mummy, i think i have had enough schooling on the screen for today. Ok, maybe, i havent actually thought about that. Lets move on, lets talk dating. Rather surprisingly, through this period of isolation, the 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 cant go ahead and immediately meet someone in the flesh . I dont get it, i mean im not single so maybe im 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 ofjust another indian wedding theres a bride and a groom. Shaadi. Com, an Online Matchmaking Service with millions of users across the world, has seized the opportunity and introduced a feature called wfh. No, its not work from home, its wedding from home, and even the lockdown couldnt 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. Wed opened to the zoom call early to, like, kind of test things, make sure if people wanted to come in early and hang out if they could, and because of that we hit the 40 minute mark before we were even ready. I was speaking my vows to christie and im, like, watching hertear up, and then im tear up and i look and in the video call, in these little boxes on the screen, people are tearing up, but its a screen like, this is our modern world now. But it was still, like, very intimate. Yeah, thats 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 tinder 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 bumble told us that theyve 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, so people are matching more, theyre having a lot more conversations and theyre turning those conversations into video chats and phone calls. And, even more interestingly, were seeing about 90 of our users who go on video calls saying they really enjoyed the experience and plan on doing it again. So its definitely not as awkward as people fear that its going to be. I do think the culture of dating will change the result of this. I think one of the most important things is people are getting used to video chatting and theyre dipping their toe in and realising its pretty great, and i think people will continue to do that after social distancing ends. I definitely think its something that people will continue to do. So, the big dating apps have found that, for their users, lockdown hasnt proved to be that much of a barrier in looking for love, but there are some other Creative Solutions starting to spring up, and 0mar mehtab 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. Bit with social isolation now in place, the dating game is being reinvented once again. Also innovating are two roommates from new york, they are rance nix and thi lam. Theyve come up with loveisquarantine, a dating format thats broadcast as a sort of a live reality show on instagram. After giving a few details on their google sheets, six people are then manually sorted by nix and lam into pandemic pods and paired up to go on phone dates with each other. Im actually going to give this a go myself, and even though its a phone date, i do have to look my best, so im going to get ready. As the evening goes on, i have to send a video to loveisquarantine after each date talking about how it went, so the audience on instagram watching this reality show unfold can keep up with the action. And for the purposes of this online show, i have to provide a short intro video. Hey there. My name is 0mar mehtab, im 29. During the round robin dates, those involved dont know what each other looks like. In all the videos uploaded, fingers obscure faces. Only if the couple hits it off are they finally revealed. The creators wanted to get right away from the normal obsession with image that you find on most dating sites to get to what they say is important. cause anything is possible for me personally, i happen to have achondroplasia, which is the most common form of dwarfism. Now, a lot of girls, not all girls, but a lot of girls are looking for the 6 4, attractive, hes got the beard, hes got the good hair, the muscles and all the things, so for me to go on a dating app like hinge or tinder, the numbers just arent great because i dont get the opportunity. People go, oh, nah swipe left, but for Something Like loveisblind and loveisquarantine, like i said, were allowing people the opportunity to get to know people, and who knows . Right, its 2am here, making it evening time in the us. And before the first date has even begun, excitement is building up in the comment. So, must admit, bit nervous. Lets see how this goes. Hey, 0livia. How are you . And as im talking away, i realise that theres little to worry about, largely in part because im not focusing on anything except the conversation. 0k, ive just had my first date and it kind of feels like the 90s, where if you had a penpal via letter or via e mail, you wouldnt see them until you actually met them in real life, but its refreshed for a social media generation. Right now im about to send a video talking about the date and how it went for everyone to see. Were excited, so keep us posted. Lets go we believe in love but after this lockdown is over, will there still be a place for loveisquara ntine . For others that do consistently use dating apps, i feel like something similar to loveisquarantine actually is a better option its just a lot more of an intentional, ifeel like, sort of approach. Its hard because i know that when i am using an app and i have all this information about somebody, i know what they like, i know that i can be more particular about it. I was may more nervous on loveisquarantine than i was in person, because i get scared of what im going to say, but when theyre in person there is a connection and theres more back and forth. For better or worse, when dating apps came in, they changed our culture. In this time of isolation, were still relying on technology but re learning how to connect with people, so maybe the art conversation isnt dead after all. Oh, what a lovely, lovely piece of tv that was. That was 0mar, hes online now and before we go any further, mate, can we just have look at 0mar again when hes dressed up all posh . Right, there. Can i say, posh clothes from the waist up but youre still wearing your shorts, whats going on . I decided to go smart casual, so smart on top and casual on bottom, as per usual brilliant thats brilliant this did seem to be as much reality tv as it was a dating app. Did you feel like you were actually on real dates . I really did, more so than i would if i was on a real dating app, usually its full of pictures and youre swiping depending on how someone looks like, but here youre forced into a conversation for about 30 minutes to an hour to really get to know the person, as you really would on a date. Of course many people are, in all honesty, quite bothered about looks, arent they . They are, and thats why this is stripping all that back and focusing it on all personality, so the person you could be dating in the future, youre really getting to know them and whether or not theyre someone thats, you know, compatible with you. Listen, 0mar, thanks for doing it, what a great sport and ladies, youd date this man, wouldnt you . Youd absolutely date this man im nodding, im not single, but yes, 0mar is lovely im afraid thats 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 are up to, albeit from home, throughout the week on youtube, instagram, facebook and twitter bbcclick. Thanks for watching and well see you soon. Bye bye. Hello. April is a month often known for its showers. Thats unlikely to be the case for this april, however. Its turned out to be particularly dry across some parts of the uk. The northwest of england has only seen 4 of its april rainfall so far. Challenging conditions, certainly, for growers. Latter days of april could just redress that balance somewhat, as things become increasingly unsettled, also a little cooler as well. Here we are with sundays chart, there is an area of low pressure to the north of the uk, dont they normally bring rain . Well, yes, and this one will bring some showers to northern scotland, but the weather front pushing its way south is a pretty weak affair. Mostly a band of cloud, maybe some patchy rain later in the afternoon for Northern England and north wales. To the south though, weve still got some heat around through the afternoon, we could trigger some thunderstorms across south wales, the midlands, into yorkshire and lincolnshire through the latter part of the day. So, perhaps some heavier rain locally here, and some sharper showers across northern scotland. Showers though across england and wales tend to fizzle out as we head overnight and into monday. A much milder story across the southern half of the uk. Overnight, to the north, a risk of a frost across scotland. And heres what that weather front really marks, the boundary between warmer air across the southern half of the uk, and colder air trying to feed into the north or north easterly breeze as we look at monday. Showers across northern scotland, but actually quite a lot of sunny spells across the northern half of the uk through the day, whereas the cloud will tend to build further south. Still pretty warm in the far south east. Elsewhere, probably mid teens at best, and then showers starting to break out in the south west later on in the day on monday, as this area of low pressure winds itself up, and into tuesday, we are talking about heavier and more widespread rain spreading across england and wales. Still taking a time to work its way north for scotland, northern ireland, parts of Northern England, i think a dry day with some bright or sunny spells. For the south though, a good chance of rain for many areas, and the temperatures sitting in the mid teens at best. This is bbc news with the latest headlines for viewers in the uk and around the world. Im aaron safir. Coronavirus has now taken the lives of 200,000 people around the globe.
