on friday and last at least until the end of november. in a nationwide televised address, president macron said people would only be allowed to leave home for essential work, shopping, exercise or emergencies. businesses classed as non—essential, such as restaurants and bars, will close, but schools and factories can still open. germany's chancellor angela merkel has also announced a partial lockdown to stop the spread of the virus. bars, restaurants and much of the leisure sector will have to close for the whole of next month. the senior medical official dealing with controlling the coronavirus pandemic in the us has told the bbc president trump's political rallies are bound to spread covid—19. dr antony fauci said such gatherings, mostly without masks or social distancing, are potentially superspreading events. now on bbc news, click talks exclusively with legendary uk rapper stormzy about his appearance

in the upcoming watch dogs: legion videogame. this week... fact—checking the presidential contenders. stormzy takes us for a ride through a ride on his hometown. and chris takes us for a ride through his kitchen. welcome to click. i hope you're well. as we head into autumn, the world has some pretty big milestones ahead of us. in the short term, the biggest is the us election. the election of the moment always feels like the biggest yet. but this comes at a time

when trust in politics and politicians is at a real low. the final presidential debate has now taken place and the idea, of course, is that these debates should tell voters about the candidates‘ policies, and help them to make an informed decision at the ballot box. but as well as becoming big, mudslinging, shouty arguments, the rallies and debates have also been riddled with untruths. we live in a time when disinformation is dividing us and entrenching us, to the point where it's threatening democracies around the world. if you can't believe what you see, read and hear, including what comes out of politicians‘ mouths, how can you make the right decision? it's become such a widespread issue that some news organisations now have dedicated fact—checking

services and there are companies around the world whose sole job is to spot the lies. but keeping up with the volume of misinformation out there is a hard task. meet devika, who's part of a team of fact—checkers who were recently tasked with monitoring the presidential debates — live. but not all of her team members were human. you need to be in a position where you can take testing rapidly. sorting truth from half—truth from complete fabrication is very time—consuming, and so she had some help from an ai algorithm. if i were to manually fact—check a claim, it would take me on average two to three hours, which is a minimum, because we have to manually check all of the sources, make sure our sources are reliable. but when ai steps in, our time is reduced by almost, i think, 70 to 80%. so, we can turn a claim around in about 15 to 20 minutes, so that reliable information

is spreading as soon as possible. you'll see it as soon as it's finished, you'll see it. the first presidential debate was the team's first chance to work with the live video feed using the software. over the last four years, you have promised to repeal and replace obamacare, but you have never, in these four years come up with a plan... the aland human combination was able to fact—check 27 claims made by the candidates. now, the software performed two tasks. first, it turned what was being said into text... private health care that they're very happy with. that's simply not true. ..which was no easy feat, so, not surprisingly, it did get quite a few things wrong. but for those claims it did manage to capture, it would then consult its huge data base of pre—established facts that it had pulled out of thousands of articles from trusted sources. ok, the forest fires

in the west are raging now. they have burned millions of acres. overall, millions of claims made overnight were checked and verified by the machine alone. our confidence score is of 0.9. this means that the ai has also pulled in a link against which the extracted claim matches perfectly. even when the ai is fairly confident of its findings, they check the results before it's published. for half of the remaining claims, the ai still returned results, but with less certainty, and so devika had to pass her expert eyes over the source material first. the ai really struggled with 8 out of the 27 claims, which had to be fact—checked completely by hand. now, this process still takes a little while —

anything from 2 minutes up to more than 90 minutes for claims that have never been made before. so, i asked the man behind logically whether a late—breaking truth would still allow the lie to have its impact. when you're putting your whole weight behind a claim and saying this is true or false or, based on presently available information, unverifiable, some things you certainly gain with latency, but they're not worth losing by getting things wrong every now and then. he is a recent cambridge university graduate and he knows first—hand how misinformation can risk lives. my grandmother passing away slightly prematurely. she read somewhere that if she gave up her meds that were prescribed to her by a proper doctor and started drinking this specialjuice of some kind, that she'd live longer and she'd have a pain—free death, etc. and obviously that was all false. but beyond the very real health risks that misinformation can pose, the stories behind big political events in the past

few years convinced him that something had to be done. regardless of the outcome about those specific democratic events. itjust felt like, process—wise, something was broken with how we as individuals interacted with information online, how we were all being shoved into various filter bubbles and echo chambers digitally, and these certainly were impacting the decisions that we were making in our personal lives, but also important decisions that we were making as a society. for now, fact—checking services have become essential in this fight. but the defining change will ultimately come when the social networks are more able to stop this stuff going viral in the first place. i think it's time for a bit of star power.

what do you reckon, lara? are you up for a bit of star dust? 0h, definitely. now, many a rock star and musician has swapped the mic for a go at being a movie star. madonna has done it, mick jagger's done it, beyonce too. but these days, video games are bigger than music and film combined. so it's no surprise that some of the most famous names in rock, roll and rap have appeared in games. stormzy is one of the most successful names in the music industry right now. but he's going to be swapping his next gig from the stage at glastonbury, to the virtual streets of london in a video game. mark met stormzy to chat about appearing in a game set in his hometown, and about how the art form has grown up, and is now tackling material that talks to the troubled times that we live in. multi—award—winning rapper stormzy‘s new single rainfall has a video with a bit of a difference. music plays.

# big mac, i was making all of the noise, in a big fila jacket... it features the croydon—born musician as a video game character performing inside an actual game — the soon—to—be—released watch dogs: legion. i'm about to meet stormzy in the flesh. the game that he's appearing in is set in a nearfuture london, and has themes of protest and resistance. i'm keen to find out if he thinks that this video game has any parallels with things that are going on in 2020. music plays. # let the rain fall on my enemies, fall on my enemies... one of the game's main themes is about ordinary people banding together to resist and to fight back against an oppressive regime. do you think that that's saying anything about the world that we live in right now? it's very reflective

of the times in the sense of, yeah, we, as people, need to be coming together. do you know what i mean? like, and i think they capture that perfectly in the sense of like, your everyday person being more important than they probably realise, you know what i mean? so, yeah, definitely. a third—person action title, watch dogs: legion takes place in a dystopian version of a near—future london, a surveillance state controlled by corrupt corporate interests. the player can recruit and control any of the thousands of characters they encounter on london's streets, performing missions which will ultimately bring down the authoritarian regime. all right, everyone! stormzy plays a version of himself, and in this fictional world, he's a rapper whose message of resistance is transmitted via pirate video signal. he spent three days being performance captured at the developers, ubisoft‘s, toronto studios. so, follow the gps, that should take you there. he spent three days being performance captured at the developers, ubisoft‘s, toronto studios. so, follow the gps, that should take you there. whoa, whoa. stormz, what are you doing there? riding recklessly. absolutely recklessly.

it's about the back of horse guards isn't it, down there? it's so london, it actually blows my mind. is it special being in the game that's set in london? it's the most. i am london, like, london is me. like, i've got so much... like, i'm a proper london boy through and through, and it's my city and i love it dearly. it's a big part of me as a man and as an artist and just my character. this is mad. my bank's up there, like, literally. if i turn... for people that don't know london, that's coutts and co. coutts and co is just up here — the same bank as her majesty the queen! # now let the rain fall on my enemies, fall on my enemies... bruv, that is me. that's more me than a flipping picture. this is mental! stormzy isn't the only musician to appear in a video game. hejoins a long list of recording artists that

include the likes of 50 cent... ..and who could forget david bowie? you're not the first video game player to get your soul trapped. some efforts could be put down to cashing in on star power to shift games, but sometimes it's about an artist pushing themselves by experimenting with a new medium. and there are points of convergence between the two art forms. there's a long history of music being used for protest and to provoke thought about things that are going on in the world today. do you think that video games have the power to do that as well? 100 million per cent, like... i feel like any platform, in whatever way, shape or form, like, or whatever mediums we use as creatives and artists, is a platform for, yeah, to speak out against injustice, for it to be like pillars of truth

and whatnot, and especially with, like, video games. even down to the reach of video games is astronomical. yeah, 100%. i think, especially the times we're in, anything can be a platform to speak out, yeah. away from games and away from your music career, your bursaries to universities, to cambridge, is up and running. how important is it that you use your position to do the things that you are doing? i'm genuinely, like, so blessed. ifeel like i have so much platform and so much reach, and i feel that it is my duty and responsibility to share what i have. do you think that means that there's something wrong, that there is something that we need to perhaps think about things a little bit differently? these things are set up to address the uneven and injustices in a lot of these areas of society. so, yeah, like, there's

so many other people of influence or artists or, like, public figures doing these things to try to just, do you know what i mean, uplift those who need it a bit more. # let the rain fall on my enemies, on all of my enemies... from best—selling grime artist to glastonbury headliner, and now taking on the world of games. the south london star continues to shine. hello, and welcome to the week in tech. it was the week that the us government filed a lawsuit against google, accusing the company of violating competition law over internet searches and online advertising. facebook rejected 2.2 million ads for breaking political campaigning rules, attaching false information warnings to a further 150 million posts. and, afterjust six months, video streaming service quibi is shutting down. the start—up raised almost $2 billion for its launch, but suffered disappointing download and viewership numbers. it was also the week that nasa selected nokia to build a wireless 4g network on the moon. the proposed cellular network

is part of a plan to establish a long—term human presence on the moon by 2030. developers of the covid—i9 contract tracing app for england and wales reassured users that none of their data will be shared with the police. this followed news that contact details of people told to self—isolate by the nhs test and trace scheme in england are shared with the police on a case—by—case basis. developers say that the app operates independently of this system. and finally, would you fancy a new dress that changes with the seasons? researchers at yale university have developed a fabric with sensors and variable stiffness fibres that show the fabric responding to changes in temperature. when the fabric is cool, the particles solidfy and stiffen, and when warm they melt into liquid, softening the fabric. while microsoft and sony

are racing to be crowned champion in the next generation console wars. nintendo has done something very nintendo and said, never mind that ultra high—definition gaming, how about some augmented—reality racing cars? this is mario kart live home circuit, which takes the best—selling nintendo game and turns your house into the race track. and the way this works is pretty clever. the cart contains a camera that streams live footage of your living room to the nintendo switch console, which you use as the remote control. in the box are four cardboard gates that you can set up around your home in whatever configuration space will allow you to form your racetrack. the software can recognise the gates as you drive through them, creating the course as you go. you also get these cardboard barriers with arrows that will be augmented with animations. once you're set up, it's pretty much like a regular game of mario kart.

there are power—ups and weapons, but it's all taking place from a mouse—eye view of your own living room. you can also race up to four of these karts together to play multiplayer in your living room if you got the space, but it will need a nintendo switch console for each one. it goes without saying that you need a fair bit of space to set this up. but you can arrange it in a modest—sized living room and that is because even though on screen it looks like the karts are zooming around the racetrack, in the real world, the kart is just trundling around the living room fairly slowly. it can also make some pretty sharp turns, so you can set it up in a smaller room, although i think you get more out of this the more space. there are some limitations to the software. not all the power—ups work in the way you expect them to in a regular mario kart game. you cannot hold a banana behind your kart to protect yourself from shells. even though bullet bill does steer you around the track automatically,

which i think is quite impressive, it cannot detect obstacles, so you end up crashing quite a lot. in fact, the augmented reality layer doesn't handle occlusions. so the race course track is always overlaid on top of the camera feed. so, here, when the track should disappear behind the table leg, it doesn't, and that means you tend to crash more than you would expect, although that is a part of the madness and we do crash, your character reacts on screen. the big question for all augmented reality applications is how much do you actually get out of this once you are over that initial moment of "0oh, this is cool"? most of the players i know that still play pokemon go have turned off the camera effects because, even though they look cool, they ultimately add very little to the gameplay. and i think that may also be the issue here. but, with all augmented reality games, i'm left with the question, how is is this better than just playing the original console game? and, ultimately, i think it is not. it's just different. it is a different take on mario kart and i think that's fine. hard to say whether this will have the same enduring appeal as the traditional console game, but mario kart is the best—selling game

of the nintendo switch, so if any franchise can take ar mainstream, it's probably mario kart. that was chris turning his floor into a race track. how cool was that? brilliant. and because we can't all go out as much as we would like to at the moment, our homes have had to become our cinemas, our workspaces and our playgrounds, and that's what lara has been looking at this week. all you need is a projector. there are plenty of projectors promising to bring the cinema home, but there are also some quirkier options, as well as some that'll provide cinema on the go. it wasn't long ago that the idea of a projector turning any surface into a touch—screen, basicallyjust like a tablet, would have seemed the stuff of sci—fi. but that is what the hachi infinite does. take a look at this.

the hachi infinite mi projector, uses deep learning, gesture controls, object recognition, and what it calls skeleton recognition, to be able to identify and focus on a surface as well as respond to a human's touch. i wasn't holding out particularly high hopes for the accuracy, especially when it came to typing on a keyboard like this, but, actually, i found it was pretty good. the system runs on android and can be paired with an android or i0s device. as well as being able to search the web and use some built—in apps and games, there's in an ai—powered education feature to play with letters and blocks that it can recognise. a kitchen function is coming soon too, as is a fitness feature that's being claimed to track your moves, letting you know whether they're right or not. you can also use it to project on a wall, although when you do that, you no longer have the touch control available. it also needs to be very close

to a wall because if you do it too far away, you accidentally end up shining it on the ceiling and wondering what is going on. that's just wrong — although it is quite cool. imagine turning up at your friend's house with this. no, it's not a drinks cooler. it is a 4k short—throw projector, and pretty much everything you need should be built into the box. it streams the content, it's got high—quality speakers, and you can even operate it through alexa or google home using your voice. the viewsonic xio—iik vibrantly projects 8.3 million pixels on a picture up to 120 inches in size. the speakers provide clear, crisp sound, but maybe not up to the volume that the picture might beckon. in a device that's trying to do so much, setting it up to achieve full functionality did feel overcomplicated, though. and, clearly, the standout feature here is that it's a portable 4k projector. at the lower end of the scale is this pocket projector,

which you can connect directly to wi—fi or to your phone — maybe you want to do a slide show of some photos, or it can double up as a speaker. at a fraction of the price of most projectors on the market, of course your expectations of the viewsonic mi mini plus do need to be managed. getting set up a simple, with a dial to focus and the ability to deal with a range of file types. idid start to have a few issues. a few glitches with the apps, but the sound quality is decent and it's a pretty versatile device so at this price point, it is ok. and here's one for the kids. it comes with a parent portal so the parents can keep an eye on what the children are watching, and prevent them from seeing anything that they shouldn't. plus, it has sensors so if a child comes within 60cm of the light here, it'll automatically turn to protect their little eyes. the anker nebula astro also has all of the streaming services built in, as well as the ability to connect via hdmi, usbc,

or bluetooth, providing a screen of up to 100 inches. it's a small but solid device. the set up and the use of all the streaming apps was really slick. the picture quality was sharp and, in fact, the sound was pretty decent for these speakers. but, the price is high, and, i think, for a device aimed at kids, it may be too high. so, there you have it. a few of the latest ways of bringing entertainment home. unless, of course, you'd rather entertain yourself than spend your hard—earned cash on a virtual screen. wow, that projected touchscreen was amazing. yes, it got far more attention in my house the most of the gadgets i'm caught testing. my husband was fascinated. my daughter played noughts and crosses. i'm sorry you haven't had a chance to play. one day. 0k, well, let's go from projecting things on the services to projecting things into the sky with lasers. back injune, we told you that this laser maestro had been showing his appreciation

to carers and nhs staff by projecting love and thanks across his home city of brighton. after a trial earlier this month, laser light city is happening this weekend in leeds. with cities under lockdown and local autumn light shows unable to happen, the idea here is that 25 lasers mounted on buildings around the city will put on a show that residents can see regardless of restrictions on social gatherings. seb created all the control software himself. but this is an interactive show, meaning thousands of people were able to log on to a special website and take control of the lasers. changing the colour, shapes and direction of the beams, which can be seen up to ten miles away. as the dark nights draw in, seb's hoping that can light up more cities, and bring a little laser sparkle to these unusual autumn evenings. anyway, that is it

for this week. you can find the team online throughout the week on youtube, instagram, facebook and twitter @bbcclick. thanks for watching, and we'll see you soon. bye— bye. hello there. the weather shows no real sign of calming down over the next few days. more heavy rain, more strong winds in the forecast. we've got low pressure spinning here. you can see that on the satellite picture. you can also see this pipeline of cloud that is now ploughing in towards the british isles. a set of weather fronts bringing some heavy rain through thursday. but between these two weather fronts, there is a wedge of mild air. so, although we're expecting some wet and windy weather through the day ahead,

it will turn a little bit milder. so, here comes the rain. some very heavy and persistent rain moving in from the west as we go through the day, pushing its way northeastwards across wales, england, northern ireland, getting up across much of scotland. now, the heaviest bursts of rain are likely to be across hills of north wales, north west england, south west scotland. could be some localised flooding issues here. and it will be windy. gusts of a0 to maybe 50 mph or a touch more than that in the most exposed spots. the far north of scotland will hold onto brightness. we'll see something a little drier towards the south west later. and it will feel mild, highs of 11—15 degrees. through thursday night into the early hours of friday, we keep a pipeline of cloud, some outbreaks of rain in places, particularly over high ground in wales, north west england, also some rain working back into north west scotland. temperatures between 9—13 degrees, an exceptionally mild night, a very mild start to friday. now, as we go through the day, outbreaks of rain will increasingly become confined to southern parts of england, south of wales.

further north, we'll actually see brighter skies developing, some spells of sunshine here and there. but it will cool off through the day across northern areas, whereas the south and south east will hold onto some mild air, 17—18 degrees. and then we get to the weekend, and here comes another area of low pressure. look at all the white line squashing together, all the isobars. this is a deep area of low pressure that will bring some very strong winds, some outbreaks of heavy rain pushing eastwards. those winds gusting up to 50, 60, maybe 70 mph in exposed places in western scotland. temperatures through saturday, it will be another fairly mild one, 12—17 degrees. and for sunday, well, it looks as if we're going to see another spell of heavy rain pushing in from the west, and it will be another very windy day. that's all from me. bye for now.

this is bbc news — welcome if you're watching here in the uk or around the globe. i'm mike embley. our top stories. a tough message from a sombre president macron — france is to go into a second national lockdown translation: if we do not apply a brutal break on the contamination today, our hospitals will quickly be saturated. tough new measures in germany too, bars, restaurants, gyms and theatres will close from monday. anthony fauci, the leading virus expert in the united states, tells the bbc that president trump's campaign rallies are bound to spread the coronavirus. we have congregations of people not being separate from each other, crowds that clearly,

thatis other, crowds that clearly, that is a situation that
