Sunshine and also heavy showers across Northern Ireland, scotland. Northern and Eastern England bright and drier with sunshine towards the west. Hello. This is bbc news. The headlines. One person has been killed and many others injured as a far right rally in charlottesville, virginia saw violent clashes between White Nationalists and counter protesters. The chancellor, philip hammond, and International Trade secretary liam fox have said that any brexit transition deal would be time limited, and would not be a back door to the uk remaining in the eu. Raila odinga, the defeated candidate in the kenyan president ial elections, has urged his supporters not to go to work on monday over the disputed election result. Now on bbc news its time for click. This week unexpected item in the bagging area. Giving vr a good kicking. And, going up . Err, sideways. This month marks the 25th Anniversary of the Self Checkout. The first one was installed in new york on 5th august, 1992, in price chopper. So what does its inventor, doctor howard schneider, remember of it all . I hadnt gone shopping much, so i went to the supermarket near my house with a stopwatch. And i started looking at people checking out, and my stopwatch went click, click it was a mechanical one. And, you know, isaid wow, what a great environment. This is so messy. Good luck with any machine doing it, and i said, this would be a great, Great Problem to solve. And then i started building a machine in my garage. I actually spent every cent i had on parts, and i got the first machines built. See, i love self service checkouts, but then im a control freak. But i do believe they save you time. Until they go wrong, at which point they become a right pain in the bagging area. The technology in the machines now is less than it was 25 years ago, using 286 computers, using ms dos 3. 3. I had Better Technology 25 years ago than what you see now, which is the reason for a lot of frustrations. Please wait for assistance. Unexpected item in the bagging area. Please remove item before continuing. So now people are thinking outside of the shopping basket, to try and update the Self Checkout and reduce the delays further. In japan, reggie robo takes your basket and bags your shopping for you. The system, which was trialled at the beginning of the year, scans the rfid tags on all the items at the same time. Since december, the Amazon Go Shop has been undergoing testing in seattle. Once it is working, shoppers should be able to pick up their items and simply walk out of the store. Swedish Cafe Company Wheelys is working on a similar idea, although this staff less shop will even come to you. Here at canary wharf, in london, something less spectacular, but which seems to me more workable and more scalable. Grab and go has been invented by ba rclayca rd. The app scans bar codes as you grab items off the shelf, and then you just go. Payment is taken from the card that is linked to the app, and the receipt is sent to the phone, so you dont have to wait in a Checkout Queue at all. But, with all that grabbing and going, are you thinking what im thinking . In the future, if youre scanning things and then just putting it in your bag, and then just walking out, and all the doors are open, i can see more people stealing more stuff. So you can basically very easily pick up some item and then can walk out, but on the way you have cctv, you have a man on the ground basically monitoring all of that. It works in exactly the same way. So its no more secure than a self scan checkout, but i do wonder how many people would just accidentally miss that barcode, and leave with a lot of unpaid stuff. Although, even here, technology might be able to spot them. Supermarket giant walmart has filed a patent to incorporate facial recognition, Blood Pressure and heart rate monitoring into its stores to try and understand Customer Frustration at checkouts. It might improve customer service, but previous trials of the tech have been used to try to spot shoplifters, raising a few Security Concerns along the way. In fact, just this week, the supermarket announced it is also trialling a scan and go solution, but this one relies on Shop Assistant Approval before you can leave. In china, which is home to several Unmanned Stores like this one, you need your face to get in the front door in the first place. Like barclaycards grab and go, customers scan items using their phones, and they can even heat up their grub in the microwave inside. Speaking of heating things up, a similar chinese idea, bingo box, ran into problems when one of its glass clad stores began to overheat. Now, as it was unmanned, it wasnt until customers began to complain that the sweltering temperatures were ruining the food inside that the shop was shut down. It is now back up and running, and everything is cool. So its not all plain sailing for these souped up shops, and it will be a while before we buy our weekly groceries in the store without some form of Human Interaction or intervention. But, as our patience wears increasingly thin in this age of grabbing and going, its no surprise that Bingo Box Plans to open 5,000 more stores in the coming year. Premier League Football starts again this weekend, which im reliably informed is important to some people. Seriously, though, fans will be excited to see what their clubs new signings have to offer. But how do you know if a new player is going to be right for your team . Well, one company is using Virtual Reality to identify talent, and also help players to recoverfrom injuries. Here is carol hawkins. Im in manchester, home of great football, to check out a small start up that isjoining up with premier league clubs for an idea thats only eight months in the making. Ifeel like im doing pretty good. This vr system helps scouts recruit players by using statistics from virtual gameplay to decide whether or not a player would work for a team. But it separately is also being used to help injured players get back to full fitness, mentally and physically. You have injured players who will often spend anything from six months to ten months, years out of the game. And the scientists, the physios will work with them, but we do not know what theyre going to do in a situation, what decisions theyre going to make. Now, they can play games, as well as having the treatment. The movement might be limited, but they can feel a part of the squad. They are using an htc5 headset, with the usual Hand Controllers attached to shin pads. And the kit is wireless, crucial for football drills. As well as this version, they are also working on one for goalies, which will require an extra pair of sensors. Several premier league clubs are signing up to use the vr system, because it promises to bring players back from the bench faster. And the first question they ask does it feel like a real ball . You do feel like youre really hitting the ball, its quite strange. I dont know if it is the sound, or the visuals, but it is very immersive. And i know people always use that word for vr, but it does feel as though you are hitting it. But, of course, youre not. And because you are not, its important players dont try too hard, and injure themselves even more, especially when theyve Cost Clubs Millions of pounds. We had an injured player last week who is not allowed to kick a physical ball. Hes fit, he could probably run a marathon, but the injury means he cannot do it. He got in this and it was basically a case of, ifeel like i am kicking a ball. Psychologically, it is massive. I am now in the rehab drill and there is a man to my left who is tracing a s with his foot. Now, i cannot do that, because my balance on these prosthetics just is not there. Sorry, physios but i can see how that would be very useful for injured players, but not just injured players, in hospitals. Players will complete a set of exercises and drills which will be scored, and their fitness can then bejudged by coaches. Elsewhere in the sport world, American Football is embracing vr quickly. Strivr there is a company out of stanford university, currently working with seven nfl teams to allow players to practice anytime, anywhere, without the same physical tolls. And in the netherlands, another vr company, beyond sports, has a contract with both arsenal and stoke city for Match Analysis and vr training. But, back in the uk, a man who Won Premier League titles as a player and coach with Manchester United thinks the new technology can really help. I think it benefits both amateur, professional and grassroots. You can put pressure into the situation. The technology is part of sport now. Football, possibly, have had a reluctance to use it, but its moving in that direction. But the kit they are offering is not cheap, with packages starting at £5,000, and increasing to more than £20,000 a month. But the potential benefits of vr to the Football Clubs that can afford it are intriguing. Coaches want to train and test footballers in the most effective way, by recreating the pressure and intensity of performing in a packed stadium. So what would the manager with the most premier League Titles under his belt, sir alex ferguson, think about it . Do you think fergie would have been up for it . He would have a look at it, yeah. I think he would. He was open to all that sort of stuff, as long as it made a bit of a difference. Or sometimes its what people like, you know, players like it. They like something new and fresh. Top clubs are big businesses, and the money in football is only going to increase. And, as it does, teams will be looking for any way to improve. As you watch your team this weekend, remember that last minute winner or fingertip save might be the result of some hard hours spent in a virtual world. Hello, and welcome to the week in tech. It was the week that the us military announced it might shoot down civilian drones if they fly near american bases. And, the Telephone Numbers and e mail addresses of Game Of Thrones stars were leaked by hackers demanding a ransom from tv network hbo. Faceapp has pulled a new feature labelled as racist, which allowed users to edit selfies into caucasian, asian, indian, or black. And social networking Behemoth Facebook is taking on tv and youtube by revamping its video offering. Labelled watch, it would feature specially commissioned shows, as well as cat videos and clips of people falling over. And disney is going to pull its content from netflix, after the House Of Mouse announced that in 2019 its launching a rival video streaming service, dedicated to Family Friendly disney fare. Dont you worry, pal. You had a good run theres no word yet whether the service will show any marvel or lucas film content like star wars, which disney also owns. And finally, the man who made passwords a massive pain now says much of what i did, i now regret. Bill burr created the Us National Institute of standards and technologys guidelines, including things like changing your password every three months and using complicated character combinations. He now thinks this is a waste of time, as people still pick rubbish passwords which hackers can break. They are just harder for us to actually remember. Weather, particularly in britain, can be changeable at the best of times. For all the dramatic change to come over the next 2a hours, i should know, having spent a decade as a weather presenter beforejoining click, its notjust about knowing the forecast, you also need to be prepared whatever the weather. And, if you are not that organised, luckily i found a couple of devices that should be able to help. Sunflower, open. This Prototype Autonomous Sunshade can be voice controlled, or use Artificial Intelligence to know what to do, when. Ok, the main function here is probably pretty obvious, and that is to protect you from the sun. This device aims to be a little bit more clever than that. As the sun moves throughout the day, the top of the umbrella will also move. The panels on it will be harvesting solar power and also making sure that you get maximum protection wherever the sun is. So some of the other functions in here . Well, there is a camera and a microphone providing security when you are out. Theres also the ability to be able to play music i ask it now, through Voice Recognition i should be able to do that. Sunflower, play classical. Classical music plays. By launch later this year, it is expected to be able to fully connected to the smart home, as well as virtual assistants amazon eco or google home. All very well if a price tag of up to £3000 does not bother you. Sorry, hang on, ijust need to charge my phone. And for those moments the sun isnt shining, well, you wouldnt want your washing getting wet, would you . So, how about a smart clothes peg . Peggy is still at prototype stage, but the finished product aims to be able to track ultra localised weather using these sensors within the device, as well as pulling data from online forecasts so you know whether you should be putting your washing out or not. Handy, if it works. But for keeping yourself dry, well, a few smart umbrellas, in all shapes and sizes, have emerged in the last few years. As much as this umbrella may look difficult to miss, it is, of course, quite easy to leave your umbrella at home when its going to rain, or just to leave it anywhere, but this connects to your mobile phone so it should stop you from being able to lose it. If you move too far away you will receive an alert and if you wake up in the morning and the internet says it is going to rain . Well, you will get a reminder on your phone to make sure that you take it out with you. The problem was, i did seem to get more alerts than were actually required. If you are taking a trip to the beach this summer, then hopefully your issue wont be rain, but it could be thirst. So, if youve been waiting for a drink Delivery Service to bring cold drinks to your sun lounger, then you are in luck. Well, at this estonian resort, anyway. The Cleveron Drone aims to safely drop off drink orders from two meters above. Im not sure i would opt for something fizzy. The Company Claims this is the fastest Response Time ever for commercial drone delivery. So whatever the weather has in store for you this summer, you now know how much better prepared you could be in the future. I seem to be living in a time when all of the tech from my favourite childhood sci fi films is coming true. We kind of have back to the future hover boards, we do have jet packs from the james bond films, and Robot Vacuum Cleaners from the jetsons. And kate russell has been to stuttgart in germany to uncover the latest storybook tech turned real. The picturesque town of rottweil, germany. Home to fearsome dogs. Chocolate box buildings. And a 246 metre Tower Housing the tallest Observation Deck in germany. That this tower isnt just about great views. Built by Elevator Company thyssen krupp, it has 12 lift shafts running inside of it. One is used to transport passengers to the top. The others to test the latest in elevator technology. As buildings get taller, life gets more complicated for elevator engineers. If a building is reaching a certain height, it has the tendency that the wind and the sun brings a certain sway to it. Its actually a big problem for the traditional elevators. If the frequency of the ropes equals the frequencies of the building sway, you get harmonics and things happen which are not so good. To counteract this sway, Thyssenkrupp Have installed a mass dampener, weighing in at 240 metric tonnes. It can also be programmed to create sway and test how their tech handles different weather conditions. Theres also the thorny issue of what happens when things go wrong. The tower houses a 250 metre fall shaft, which is used to drop things from a fantastic height, to see how they break. Argh whoa thats going to 30 into the ground. Thats mad. That makes me feel quite dizzy. The tower is also used to test ideas designed to tackle some of the biggest problems facing high rise living. Already today, lifts take about 40 of the usable space of a building. If you build higher, you need more lifts, and you are ending up with only lifts, which makes no sense. So our inside area is in the core of the tower. And only a few people really have the chance to see what we have built, and what is running there. An elevator without any ropes, so this is something revolutionary. Instead of steel ropes, the cabin is carried by linear motors, the same tech that drives japans bullet train at 500 km h. As well as eliminating the speed and height restrictions of todays tech, it allows passengers to travel sideways as well as up and down, just like willy wonkas fantastical elevator in charlie and the chocolate factory. Behind the scenes, behind the car, we change this exchanger 90 degrees. Get prepared for the Horizontal Movement while people are entering and leaving, and as soon as the doors close, we can go sideways to the next shaft. This is th
