this is bbc news, the headlines: the british prime minister borisjohnson has confirmed a four—week national lockdown in england to try to halt the rising number of coronavirus cases. from thursday, people will be largely restricted to their own homes. schools and universities will stay open but non—essential shops, including bars and restaurants, will close. the us presidential candidates are making a final weekend dash around swing states. donald trump is in pennsylvania and joe biden is in michigan — both states that could be key to winning the white house. rescue teams in turkey are working through the night to pull survivors out of the rubble of buildings, crushed in friday's earthquake. the mayor of izmir confirmed that 38 people had died but more than a hundred have been pulled out alive. the president, recep tayyip erdogan, has visited the area.

now on bbc news, click. halloween is here and this week, we have robotic tricks... ..sailing treats... ..eerie earbuds... ..and... screams. ..a presidential election! welcome to click. i hope you're 0k. listen, halloween might not be happening outdoors this year, but i tell you what — it's certainly happening indoors here, at least. let's cross to lara's

haunted house and see what horrors await. wow, you've got lots of halloween there! uh, yeah. turns out i do. do you think i've overdone it slightly? oh, no, i love it! you've gone stylishly minimalist as always, i see. yeah, all i could find was this skeleton in my closet. i don't really have anything else to decorate the house with. do you know, i've never been trick—or—treating. have you not? well, look, many of us won't be trick—or—treating this year but there are some people who try to make it as safe as possible for the kids who do pass by. trick—or—treat! this is luke keys from austin, texas and he's out to save halloween. he's been finding ways to dispense sweets from a distance. he's experimented with dropping them from a drone and even firing them from an air cannon. but i think his star creation is this, artie the robot. after eight years of tinkering, its latest skill is distributing socially

d ista nt sweets. it runs on arduino microcomputers, weighs in at about 140 kilograms, and has been shrunk down to avoid scaring the kids. just readjusting the lighting to something more sensible because straight after halloween, there is another american horror story. never mind who wins, the run—up to the us presidential elections has been a political nightmare for many. two candidates yelling at each other, misinformation completely clouding the very real issues that the country is having to deal with, and of course the debate over whether masks are too scary to wear. now, for a long time there have been attempts to try and engage younger voters and also to make voting more accessible for people with disabilities. in the us, a few states have been running small trials

to see whether technology can play a part, and james clayton has been to one of those states to see it in action. america is about to hold an election that feels like a crossroads for the country and already, tens of millions of people have already voted either by postal voting or voting early in places like this. but is there a simpler, more technologically advanced way of voting? you can do your banking, even your tax returns online. so, why can't you vote digitally? well, you might not know this but in some states, you actually can. this is terra from west virginia. she's been disabled since the age of two. it was very simple. i mean, literally in less than 15 minutes, i had gone online, entered the information, got my ballot, voted, signed it, and sent it off.

several companies are trialling mobile voting in this presidential election in a very limited way. those who are eligible are members of the armed forces and people with disabilities. one called voatz does it by mobile. another called democracy live uses web browser. so, how does it work? when finished filling out your ballot, select continue at the bottom of the page to move on to the final step where you will sign your ballot and review your ballot packet. well, every state is different but all of the pilots need some kind of verification that it's actually you. that could be facial id or a photo of your id or a signature. then, it acts very much like a postal vote. that's until you send it off. voatz uses block chain to store your vote. democracy live keeps the data in amazon's cloud. a copy of your ballot is also printed out.

the voatz app is being trialled in a county in utah. democracy live in west virginia, injurisdictions in oregon and south carolina. it's not a huge trial. at most, a few thousand will vote this way. the pilots are all being funded by this man, bradley tusk. an early investor in uber, he's got deep pockets and big ambitions. you know, i'm not doing this just because i want to make it easier for military to vote or people with disabilities to vote but because i want to radically increase turnout overall so that we move things into the centre, right? and so that everybody votes, and that means having technology that can handle millions of votes. so, why aren't we all e—voting? why aren't we all voting on our mobile phones? well, it's because there are a lot of people who are very sceptical of the technology, and some believe there are some serious security flaws with some of these apps. i caught up with michael — he's reverse—engineered these two electronic voting systems and says he's found security flaws in both. i'm definitely surprised

that it was as easy as it was. i think there's a lot of things they could have done to make it much harder, but overall, those sorts of problems are not necessarily solvable in using the current technology, which is one of the reasons why we wanted to take a look at this system in the first place. here's the example he gives. remember the online banking comparison? well, this is why he thinks that's not a fair parallel. when you bank online, you can actually see a transcript of how you, you know, spent your money, and you can say, "hey, that one is this transaction, says that i spent $500 in the uk, but i live in boston and have never been to the uk, therefore this is obviously fraudulent, right? " you can't really do the same thing with voting because if you can prove the way that you voted, if you can have this transcript, someone else can get a hold of it. i put some of these criticisms to both of these companies.

first, democracy live. at some point, we can't hold back the tide, right? next—generation voters are going to demand next—generation voting technologies. we're going to learn lessons, right? that's why we're starting small and responsibly with voters that would be otherwise disenfranchised. we don't have all the answers right now. the academic community and the security community don't have all the answers. that's why you do smaller responsible testing, learn the lessons, and then build from there. and that's what we're trying to do right now, and we're starting with groups that today would be otherwise disenfranchised. i put those same questions to the founder of voatz. obviously, it's new, so there will be criticisms. so, we welcome the scrutiny but at the same time, a lot of that is hypothetical. just by looking at one piece of the system without actually transacting with the system in any meaningful way often

would lead you to incorrect or incomplete assumptions. so what did terra think of her experience of voting online? i like it for people with disabilities because it gives us options and we need options, because some of us just can't get out. some of us require special tools in order to write or speak, and i think that it's a good option for people like that, but i am not necessarily an advocate of electronic voting without a lot more security around. both types of voting have been used before in local elections and both companies say they've never been successfully hacked. is e—voting the future? are voting stations like this the past?

well, not so fast there because even the advocates of this technology say that technology is not quite there yet, which does rather beg the question why is it being tried in a us election? but perhaps these small trials may help to one day offer another safe and secure form of voting in america — just maybe not quite yet. james clayton there. of course, this isn'tjust a debate limited just to the us. the pandemic has played havoc with elections around the world and the arguments for and against online voting systems have been given new life. but in one country, it has been a reality now for well over a decade. way back in 2005, digitally—savvy estonia became the first country to allow online voting in elections. skip forward to their 2019 general election and 44% of voters filled out their ballots online. and there have been other examples of positive engagement

with internet voting across the world. back in april, the labour party elected their new leader in an online ballot in which a 70% of its 550,000 members voted. this way of voting makes a lot of sense — it's less expensive than the traditional in—person system and for many it isjust easier. and could online voting be the way to engage a younger generation? as time goes on, online voting will become more and more important for young people. because society will become increasingly digital, increasingly online, whilst at the same time our voting system will look exactly the same as those that existed in the 1800s. therefore you are going to have a big divide between democracy and the way that people live their lives. we can have elections, but there are still thousands of people who can't physically vote, and therefore we have elections but we're

not a full democracy. however, many claim that online voting is still too vulnerable to cyber attacks and security breaches. malware could tamper with votes before they reach government servers, and hackers could create mirror versions of an election portal, steal voter credentials, or even attack the computers that count the ballots. but in estonia, there have been no serious security issues. however, crucially, online voting is linked to the country's state—of—the—art electronic id cards, which estonians use for everything from paying taxes to accessing health records, and not every country has such a solid digital infrastructure in place. and some countries just don't want to take the risk. after years of testing, for example, switzerland was hoping to push forward with online voting — but in 2019 decided to end trials after flaws were uncovered in

the proposed system. regardless of whether you're for or against internet voting, all would agree that the stakes could not be higher than in major elections where there can be zero doubt cast on the outcome. so we may have to settle for waiting in line at the ballot box for a little while yet. hello, and welcome to the week in tech. it was the week that harley—davidson revealed its electric bicycle, the serial1 will go on sale next march. the ceos of google, facebook and twitter, face hours of questions from us senators on censorship and misinformation on their founders, and alibaba founder jack ma's new online payment group detailed his plans for a stock market debut next month. it's said to be the world's largest ever. it was also the week that spacex satellite internet service started recruiting beta testers with low expectations to test its broadband.

for a fairly steep $1199 a tester will get a router and terminal to connect to the satellites, giving access to what an e—mail describes as "better than nothing" internet service. the release of the highly—anticipated game cyberpunk 2077 has been delayed again until december the 10th. a letter from the developers cd project red apologised for the further delays and said they knew the announcement would raise emotions and questions. spot, the boston dynamics robot dog, was sent to chernobyl to help sniff out radiation. 3a years on from the disaster, 200 tonnes of radioactive fuel is estimated to still be in the area. and finally, we met another robot named spot who's also learning to behave like a dog. a team from johns hopkins university are training this robot using dog training techniques of positive reinforcement. when it performs a task well, the robot gets a treat. researchers say it can achieve in two days what would usually take a month of training.

the headphone market is seriously overcrowded, so companies are having to get a little bit more creative these days. take a look at this, for example — it looks like one speaker, and it is in this form, you call this party mode, but you can also separate them into two and place them up to 22 feet apart to create stereo sound. plus, take a look inside and you've got a pair of true wireless earbuds. each part of the duolink go speakerbuds has six hours' battery life, and the buds can be recharged when they're sitting in the speaker. i've had a bit of a problem with getting earbuds to fit and stay in my ears. now, as i've often said before, this may be because i have strange ears, but these ones actually fit very well, so they're great for strange ears. this isn't the most amazing audio i've ever heard but for something so versatile at this price point, i don't think i complain. and now something for a quieter life. cocoon relax are claimed to be the world's first sleep—aiding headphones, so they hope

to help you get a better night's sleep but they could also give you a little bit of relaxation during the day. hm, i can't really do it here, can i? yep, i got to rest on thejob again. they use cognitive behaviour therapy methods to provide relaxation as well as being full of biometric sensors. the device's eeg sensor aims to track brave waves along with monitoring motion and heartrate, combining them with info on the user's environment. this allows them to personalise the programme — for example, change the audio when you've fallen asleep, or if there's some background sound, then add some white noise. you do, of course, have to buy into the idea that you would want to sleep in a pair of headphones. admittedly, they are extremely comfortable, it is just that if you try to move away from your back, it is quite hard to keep them in place. also, i do sleep pretty well and, to be honest, i don't really have much desire to relax —

which maybe means i actually need to — so i'm not sure i'm really their target market, but the thing i can see them being very useful for would be on an aeroplane, not that i'm actually travelling anywhere right now. an earbud version is coming soon too, and there are plenty of other wearable sleep devices out there, including other earbuds aiming to help you get the best out of your slumber. here, i have the quieton sleep earbuds. one of the things they can do is use noise cancelling to get rid of any snoring. hopefully they can do that for my own. i tried them at ces a little while ago on the show floor, but now i can test a pair to go to bed. with ten hours battery life, there's plenty of time for good night sleep. the noise cancelling and flattening did a greatjob of dampening down low—frequency sound and they were surprisingly and comfortable,

but the one on the side i was sleeping on kept falling out by the morning, which is clearly a problem. although maybe my strange eears are to blame again! yes they do a better job than foam earplugs, but they do so with a pretty hefty price tag. but if you simply want a bit of silence, or at least some of the time, then these prototype earplugs are an interesting proposition. the idea is you place them deep inside your ears — as absurd as it sounds i actually had to watch the video to find out exactly how to do it because it's not at all instinctive — but once you place them inside, further than i thought anything could actually fit in my ear, byjust using this dial at the side, you can reduce the volume around you by between five and 38 decibels. to put that into context, the company claims that's losing around 80% of household sound at its highest. and if you keep it on its lowest it barely makes a difference and the reason that would be useful is the company's premise is that you would wear them all day. you simply adjust them as to whether you want to turn

up or down the volume of actual life. these are just the prototype, and i wasn't really sold on the idea that i would want to keep them in all day, but if you, do with no battery and having been sitting in the depths of your ear canal, then you may be pleased to know that they can be washed in soapy water. wow, they look like they go right in — did they touch your brain? yes, i think so — it felt like it! 0k! now, you may remember a few weeks ago we took a look at the america's cup, a sailing race at the cutting—edge of design tech. this week, we're going back to sea — this time for the start of a round—the—world race with a twist. all of the sailors have to do it completely alone. travelling 27,000 miles, it takes competitors 80 days of constant sailing. they can only pause for 30—minute bursts of sleep. so, naturally, this can impact their mental health. and one competitor is taking

on some tech that she hopes could come to the rescue. zoe kleinman's been to the south coast of england to find out more. this is pip hare. she's taking part in this year's vendee globe race. i don't think there is another sporting event on the planet that asks so much of human beings. pip‘s trying to beat the world record set 15 years ago by dame ellen macarthur. the challenge is physically tough both on the sailor and on the boat. but something that can be overlooked is the mental health strain of being completely alone at sea for weeks on end. it is why pip‘s team is going to keep a eye on her well—being. pip‘s boat is kitted out with every gadget you'd expect on a 21st—century craft. autopilot, gps, led flares,

but what sets it apart is that mental health tech is also part of the package. i'm really interested in how you're going to cope with being completely on your own for such a long period of time. so, it is a long time at sea but i'm really not alone, i'm well—connected. i have two satellite systems, i can upload video, i can whatsapp chats... and this connection to shore is where this 20—year—old yacht truly becomes cutting—edge. pip‘s team plans to use artificial intelligence to understand how she's really feeling from the videos she shares during her voyage. it's looking at the text that's been transcribed from anything anybody says, and it's giving us a sentiment about positive, neutral, or negative, about what's being said. and then it's also looking at your facial expressions as you are talking to identify emotions. anything from joy to effortful

thought to emphasis as well as things like contempt and disgust. so, when pip uploads a video, say something like this... it's my last day in port today. it ends up in a system that looks a little like this, which picks up all of the different emotions that she's experiencing. this then allows her team to work out how they might be able to help her. it's really do...we sense that pip isn't asjoyful as she has been over the past week and do we want to have another phone call that really tries to lift her spirits? but to give it a fair trial, i thought i'd have a go, too. and i don't think i'll be needing a pep talk any time soon — i seem pretty chipper. back on land, this technology is used to do market research, analysing video uploads from customers. it basically replaces the focus group and medallia claims that lets companies monitor emotional responses to their products.

but when it comes to this race, i'll be interested to see just how useful it is. the team is still limited in what support it can provide remotely. looking after pip‘s mental health includes helping her make good decisions especially when she is tired. she plans to survive on just 30 minute bursts of sleep. it is not always easy to understand how well my cognitive function, how it might be impaired, or how well it is functioning. so i am working with a company who specialises in monitoring rare health conditions for patient management. and they have written me an app that will help me assess my own cognitive ability while i am out there. for me if i am about to make a big decision, maybe i might decide to have a bit of a sleep before i make the decision. this app called oxygen gives her regular promise to complete basic

maths challenges, a bit like brain training and the speed and accuracy of her answers indicates how good she is. and accuracy of her answers indicates how alert she is. i get a notification through my wearable so there is a forward memory task where i recall the numbers in a list going forwards. there is a backwards memory task, same againjust a little bit harder. without the app i would just do it through mental arithmetic tasks but the app gives a bit of regularity to what i am doing and then we're also collecting the data so that we can learn from it when i get back. it is crazy to think that the next time i come back i will have sailed around the world. that was zoe kleinman with pip hare. we wish pip all the very best of luck for the race. that's it for click this week at halloween. lara, what on earth?! well, you clearly didn't think i was making enough effort, so i'm now mixing you up something in my cauldron.

anyway, you can keep up with the team throughout the week — won't that be fun? we're on youtube, instagram, facebook, and twitter @bbcclick. thanks for watching, and we'll see you soon. echoing: bye! hello. storm aiden brought torrential rain and gales to a large swathe of the uk on saturday. those strong winds really whipping up the waves, particularly across southern and western coasts. but as the rain eased and the skies cleared, it's been an opportunity through the night for many to see the blue moon — a second full moon this month — but it's only a brief respite from the rain. there's more to come overnight and into sunday. still a number of met office warnings in place for both

the rain and the wind, and all the details are on our website. so this is how sunday shapes up. this is the area of low pressure responsible for storm aiden, now pulling away northwards. a second area of low pressure to the north—west of the uk, and notice how the isobars are tightly packed together, so it's another windy day. and we start the day for many very wet as well. that rain will clear away eastwards and behind it, some spells of sunshine, although also some showers piling in from the west. and then another band of more persistent rain arriving into northern ireland, southern scotland, northern england, the midlands and wales, maybe south—west england later in the day, some heavy and persistent rain and also across the western side of scotland. temperatures in a range from ten to 17 celsius. it may not always feel that way, given the wind and the rain. and those winds still very much a feature, particularly across western scotland, where they could still exceed 70 miles an hour in terms of gusts. and that rain keeps on falling through parts of northern england, wales and the midlands as we go through sunday night and into monday, also pushing into parts of south—west england as well, slowly starting to ease.

and we start the new week very mild indeed — overnight temperatures not that much different from what we will see in the daytime. so this is where we are on monday. that frontal system starting to pull away but still showers or longer spells of rain pushing in from the west and still another windy day, so it's quite a messy picture to start the new week. if you like the weekend weather, it's just lingering into the new week. some places may manage to stay dry but those showers never too far away. and temperatures again in a range from 10 to 17 celsius, so we are still fairly mild, but not for much longer. the winds definitely are still a feature, still quite gusty but gradually easing down, and that process will continue as we go through tuesday and into wednesday because, finally, we start to see an area of high pressure starting to build across the atlantic and heading our way, so that will start to settle things down. the winds will become lighter, it will generally become drier but with that it will also turn colder, both by day and by night.

this is bbc news, with the latest headlines for viewers in the uk and around the world. boris johnson announces a four—week national lockdown in england. he says no responsible prime minister could ignore the surging rates of coronavirus infection. the virus is doubling faster than we can conceivably add capacity, and so now is the time to take action, because there is no alternative. as the last weekend of campaigning hots up, trump and biden make a last bid to voters in swing states that could be key to winning the white house. the most powerful storm of the year. typhoon goni strikes the philippines, bringing wind speeds of up to 225 kilometres an hour. the film world pays tribute to sir sean connery,
