Throughout the day. The winds will remain light, and will continue with overnight frost for the next few days. Here it is, this area of High Pressure which has been building in, pushing that low pressure northwards and taking the showers and the breeze with it. The temperatures and the clear skies, light winds will all plummet tonight with widespread, pretty hard frost, particularly out of town. Northerly wind could just bring one or two showers to eastern parts of norfolk and to eastern kent, but High Pressure dominates the scene for part two of the weekend, so another largely dry one, with light winds. You will notice more isobars and weather fronts in the north west of the uk. This will bring more cloud to the north west of scotland, perhaps some spots of rain for the northern isles, and it will be windier too. So, temperatures nine or 10 celsius for stornoway, but elsewhere, after a cold start, it is going to be a cold afternoon. Hello, this is bbc news. The headlines contenders in the race to replacejeremy corbyn as labour leader call for unity as they take part in the first hustings of the contest answering questions from Party Members in liverpool. Businesses warn of price rises, after the chancellor, sajid javid, said there would be no alignment with eu regulations after brexit. Heavy rain and thunderstorms dampen bushfires in eastern australia, but bring flooding to some areas. British scientists suggest the number of people already infected by a new virus emerging in china, is far greater than official figures suggest. A crack down on alcohol fuelled holidays in majorca and ibiza as pub crawls and happy hours are banned in 3 popular resorts. Now on bbc news its time for click. This week, we are staring into the future. We are self driving around china. That is a bit creepy. And we are flexing our. That looks painful not quite. Give me the chime, im doing it ca rs. They are always one of the biggest draws at tech shows and last weeks ces was no exception there were plenty of innovations inside the vehicles and out. Say you wanted to rent this beauty for the weekend, and when you returned it there were a few dings in the bodywork how do you conclusively prove that you didnt do them . What you need are a pair of these. These are check scanners. A french innovation that can inspect a car for damage in the time it takes to drive through them. There are ten cameras on each side and Machine Learning has been trained to spot dents and scratches that can be compared to those that were there when you picked the car up. It is also useful for manufacturers to spot any imperfections in new cars, and in a world where we are buying more and more things online at a distance, these could be useful for producing condition reports for second hand car options. But much of the car innovation on display at ces was of the self driving nature. After all, whoever steals a march in this area will be in the best position to tap into the billions that this sector offers. It is taking longer to perfect them than some realised it is all about data from testing, testing, and more testing. Which is why, although private companies are at the vanguard, behind the scenes, the big nations are facing off to provide the most favourable regulations. The big rivals here . You probably guessed it. The us and china. The us was initially quicker to grant licenses to Companies Like waymo, but its superpower rival has also woken up with big deregulation plans of its own. The huge corporations on the front line, alibaba, google, ford, tesla, tencent and more are now battling to capitalise, to hone their algorithms and create the first truly autonomous road vehicle. Stephen beckett went to guangzhou to visit one of the Global Leaders in Autonomous Vehicles to find out more. This is guangzhou in the south of china. About 75 miles upriver from hong kong, it is one of chinas biggest and most developed cities. Home to around a0 million people, and now it is one of a handful of cities in china running large scale trails of self driving cars on public streets. This is pony. Ai. You may not have heard of them, but here their cars have become a common sight in the area around their head office. Over the last year they have been running an Autonomous Taxi Service in the city. At the moment, the trial is only open to selected family and friends of pony. Ai employees. Pretty good deal though if you can get access, as it is completely free. With just a few taps on an app, an autonomous taxi will come straight to you. So this Autonomous Taxi Service is operating all around the district of nansha, in around a 100 square kilometre area, mainly the urban bit. So we have quite a lot of choice of where we can go. Where shall we go . That is a bit creepy. The driver has got his hands in a kind of ready to go position. There is some chap driving on the wrong side of the road just there. The car did slow down a little bit. Braking. But seem to have got through that one unscathed. What is interesting is some of these things just dont happen in other places in the world. If you are building a self driving car in the us, then your car might not know what to do if it sees someone driving on the wrong side of the road for the first time. But here, fortunately, people are driving wherever they like. But making sure vehicles like these are safe enough to roam free without a back up operator is the next big challenge for Autonomous Car companies around the world. This man leads the engineering operation here at pony, so its his job to try to make that a reality. Sometimes in each different city, the traffic pattern and driving behaviours are totally different than, say, in the us usually they obey the traffic a lot more and tend to yield to lane change, but in china the driving behaviour is more aggressive, so it is sometimes unpredictable, especially for cyclists, so you need to put everything into consideration. Its something they keep telling me here, chinese data is richer than data in the us. Right now, most self driving Car Companies are focused on getting their vehicles to work in their home countries, but once that is figured out, the rest of the world is next. And it could be that cars trained on unpredictable chinese roads will stand a better chance in places like india and africa. Pony. Ai was founded in december 2016, it is only three years old. We are almost as good as the best autonomous driving Car Companies in the us. Because the roads in america are a bit more predictable than they are here in china, do you think they will get to the self driving dream first because the problem is a bit easier in america . Actually, we think differently, because in china it is more of a challenge. I would say we drive one kilometre on chinese public roads it is like ten times more value than driving one kilometre in united states. That is why we can improve faster. This screen here is designed to give the passenger an idea of what the car itself can see. That car, this car in front of us, is represented on here as a different coloured block. Oh, you see, that was an interesting situation. These guys are pulling up, this car is coming up on our right, but the car managed to handle it stopping the driver didnt have to step in. We want to go here, i think that is why it is confused. This is a pretty confusing situation, even for a human. You can see why it is confused because it wants to go in here, and there is a lane of traffic there, so i think that is probably what i would have done as well. I am pretty impressed, it handled a few tricky situations, we had a guy on the wrong side of the road, but it didnt do anything that felt dangerous, which i think is the main thing. It wasnt exactly like a human driver, still some of the way it moves, the decisions it made, probably would feel a bit unusual to you if you were used to a human driver, but it is on the way. When it comes to technologies that are consumer facing, they dont have any obvious political impact or anything to do with content, the Chinese Government is very relaxed about letting entrepreneurs innovate first, seeing what happens and maybe regulating later. And that often is the opposite sequence to what happens in the uk or the us, where governments will get ahead of potential problems for example, self driving cars and permit regulations first and then the industry follows. The reality is that for a long time, china was lagging behind in autonomous technology, but as we know, when china makes a decision to do something, as it has here, things can happen very quickly. At the southern end of the Las Vegas Strip is the mandalay bay hotel. On october 1st 2017 this was the scene of a tragedy. The uss deadliest ever mass shooting. A gunman in one of the rooms opened fire on a crowd of concert goers across the road. He killed 58 people and injured more than 400. The incident sparked a review of security across the city, but now it is being taken further. Richard taylor has been looking at whether technology can stop would be perpetrators in their tracks. Heres the dilemma. How do you keep the Worlds Entertainment capital safe without turning it into a Party Pooping security fortress . Patriot 0ne believes it has the answer, using unobtrusive sensors which generate information feeds which can be assessed to see if someone is carrying a weapon. This vegas casino resort is now rolling out the technology, which has been in testing for the past two years. We have got various bits of hardware here. The system can be placed in a building entrance or a turnstile, and unlike a metal detector it creates an invisible fence. You wouldnt even know it was there. If i am carrying a concealed weapon on my person, or worse still, intent on an act of violence, the system as it is deployed here invisibly in these planters, can kick in, the ai making a determination of whether or not this is benign and alerting the security authorities to take the relevant action. The pat scan device works on several levels. The one thing emits residents frequency patterns that identify all the shape of an object. Another sensor creates a Magnetic Field and detects disturbances as an object passes through. But the real smarts lie in the ai algorithms. Within seconds, they assess the data against its own database to figure out if weapons are being hidden. With daily shootings in the us and a knife crime epidemic in the uk, the allure of a system to keep us safe is certainly set up. Seductive. We want to be in public schools, hotels, university campuses. We are now in the business of rolling it out. The uk market will be extremely important to us, particularly when it comes to knives because of the knife crime crisis, and in fact knives are being used by terrorist groups for mass attacks. But Ground Breaking as the tech is, it is largely unproven. How accurate is your system . Because when it comes to ai, the machine is only as smart as the data that you are feeding it. We have been out for a long time with tremendous partners who have allowed us to get a lot of data here. The university of north dakota has been hugely supportive in that way. We have built sufficiently large Data Holdings that we now have confidence in the accuracy of our systems. Enough confidence that we are now into our first commercial deployment. 0ur early adopters also understand that the systems get better and better, the more data is fed in, so they are equally allowing us to ingest data for training the system. The system isnt100 accurate or foolproof, and an assailant may well get into the premises another way entirely or the weapon may be hidden in Something Different like a metal box. An additional security layer is needed. If im openly brandishing a weapon, that is where the eyes of the system kick in, a so called Machine Vision where a Security Camera can make an assessment based on what is in my hand, based on what is in its database and if it finds it is likely to be a weapon, then it will trigger a relevant alert. The idea of augmenting human eyes with this method of Computer Vision is catching on globally. A number of outfits promising enhanced security for a person and object detection. Understandably, that leaves many people uneasy. We are very conscious of the fact that people dont want to live in a mass surveillance society, but there are very different ways in which we collect data. We dont capture any personal information or store or distribute personal information. We are looking for objects people are of no interest to us unless they are carrying a threat object. What our ai has been trained to recognise is the difference. The threats. It is not making any determination on people or capturing personal information or body image. That puts us on the right side of that line between too much surveillance and not enough security. Hello, and welcome to the week in technology. It was the week that us President Donald Trump clashed with apple over the tech giants data encryption rules. Apple refuses to unlock iphones in relation to criminal investigation citing privacy concerns. Microsoft ends its support for windows 7 after ten years, meaning users will no longer receive security updates. The Uks National Cyber Security Centre is recommending windows 7 users replace their unsupported devices as soon as they can. Londons Heathrow Airport is following a new anti drone system installing. That will allow it to pinpoint unauthorised aircraft and their pilots. The move comes as airports are looking to increasingly prevent drone disruption following a temporary closure at gatwick in 2018. Tesla cars are being able to talk to pedestrians in a baffling british accent. Car well, dontjust stand there staring, hop in in true knightrider fashion, Tesla Ceo Elon musk tweeted a video of a car speaking to passers by. The feature will be used to talk to other road users and pedestrians as well as provide a flatulence function. What a time to be alive and finally, if youve ever wondered whether your pet pooch would enjoy a podcast, spotify has introduced a new range of personalised playlist for pets. Pet playlists is a new experience, spotify users can get a curated playlist for their pets based on their tastes and pet sounds, anybody . There isjust so much to see here that ive been getting my hands, ears, eyes, nose and mouth onto wearables. First up, no this is not a pair of goggles, it is the prototype of an air purifying mask. The finished product will look like this. With claims it is 50 times more effective than the market leading cycling mask, the a0 air uses nanotechnology and air pressure to filter out harmful particulate matter. 0nce described as a multistage filtration system, it provides the process of air being sucked in. That air will then be cleaned and pushed out the front, creating your own environment of pure, clean air. Currently, the prototype is a lot less comfortable than the finished version and this is a size too large and i need a smaller one. Ifeel like my nose is being held and i probably sound like that. It will take some getting used to but it is actually adjusting according to my respiration rate, so right now the fan speed is at 16 . I can make the fan go up more if i want more air to be pumped. I feel like im at the dentist. Imagine what i could do i certainly couldnt run like this but maybe ride a bike. I dont know. It is notjust about the device but also about collecting data, localised air quality data and also respiratory information. There are some plans to use that for some health tech in the future, particularly in regards to meditation. It has five hours battery life and in time, the device will be miniaturised. Despite the fact that i thought i looked completely and utterly ridiculous, it has actually made it to the catwalk, featuring in new york and seoul fashion weeks. Back on the show floor, there was also the sixth finger. Sixto is a device for people who have limited mobility in one hand, so could be due to a stroke or Something Like that. The way it works is that you position the bad hand where it needs to grab something and this joystick, which will be held in the good hand, is used to be able to close the device so you can actually pick something up. One of the other benefits of this is that it actually encourages somebody to use a hand which isnt functioning properly rather than holding their arm in a position where it is likely to get stiffer. In the depths of one slightly more secret meeting spot, came this view into the future. This is a contact lens that provides augmented reality. Apparently, it fits like any other scleral or semipermeable contact lens. This could be used for translation where the words would come up in front of when you are having a conversation with someone. The idea is that this is all about invisible computing, that Something Like this should be less intrusive than having your phone in front of you. Wow that is incredible in a way, the fact that there is little enough information for it to not be totally distracting makes it better. I think if they put too much up it would become too overwhelming. While i wasnt allowed to wear it, just holding it up, i could see some simple stats right before my eyes, which having been sceptical in advance, i was pretty blown away by. How is it possible to fit all of this into the lens . We had to build our own wireless protocol between the contact lens and another wearable accessory because we had to manage power and data and size of chip and that accessory connects to your mobile phone or the cloud, to access additional Computing Resources and information. It is very comfortable, fits to your eye and corrects your vision when you wear it. If you have a prescription, we build up a script into the lens. Heart rate data, speed, and even with your eyes shut, you would able to see this because it is lit up and obviously the lens is sitting beneath your eyelid. It feels seriously sci fi. And there you have it, what to wear, to see and feel in the future. There, never taken that photo before. The thing about coming to las vegas straight after christmas is you eat lots of f
