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 august five, 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, i said well, what a great environment. This is so messy. Good luck with any machine doing it. And i said, this would be a 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 then what you see now. Than what you see now. Which is the reason for a lot of frustration. 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 youre shopping for you. Your shopping for you. The system, which was trialled at the beginning of the year, scans that rfid tags on all of 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 staffless 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 apps 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 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 an item and then walk out, but 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 bar code, and leave with a lot of unpaid staff. 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 Fuse Security Concerns along the way. In fact, only 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, 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. 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 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 5000 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 the player would work for a team. But separately it is 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 they are going to do in a situation, what decisions they are going to make. Now, they can play games, as well as having the treatment, the movement is limited but they can feel part of the squad. They are using an htc5 headset, with the usual Hand Controllers attached to shin pads. The kit is wireless, crucial for football drills. As well as this vision, 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 as it promises to bring players back from the bench faster. The first question they ask does it feel like a real ball . You do feel like you are really hitting the ball, it is 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 you are not. And because you are not, its important players dont try too hard and injure themselves even more, especially when they have 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 any time, 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 a coach with Manchester United thinks the new technology could really help. I think it benefits both amateur, professional and grassroots. You can put pressure into this situation. The technology is part of sport now. Football, possibly, have had a reluctance to use it, but it is moving in that direction. But the kit being offered 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 Football is 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 . 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 it is 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 win 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 in a 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 did 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 thyssenkrupp, 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 swayed, you get harmonics and things happened which are not so good. To counteract this, 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, it 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. Only a few people really have the chance to see what we have built and what is running there. And 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 kilometres per hour. 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 car, we change this exchange, 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 the most important thing, that we come back to a circulating system. So, re inventing the paternoster. Using this circular pattern means a lift shaft could hold ten or more cabins. Much more efficient than the single up and down ride todays elevators are limited to. And this will only become more important when we start looking at elevators reaching perhaps 1000m or more into the sky. That was kate, and that was amazing. Not that the most impressive innovations have to be the highest tech, of course. As ive often said, some of the most inspiring innovations are those in the developing world that use pretty low technology to do really important things. Case in point, dan simmons heard about a group of people who are using a mobile phone to save lives in nairobi. Im on my way to thika, an hours drive south of the capital to see one of the first centres in kenya using phones to diagnose cancer. Its essentially a smartphone with a scope offering 42 times magnification. That allows the camera to be placed a comfortable distance away from the patient. That allows the camera to be placed a comfortable distance away from the patient. A powerful light comes with the system. Its even brightness is critical to avoid misdiagnosis. Violet, what is the biggest change that you have seen since this was introduced to your clinic . I have a lot of clients, who have to go to the Clinic Centre and somebody has to see what we actually seek. After taking the photo, we have to see the patient, and the patient themselves, when they are sick, we have this position and then we have this. So you show them the picture. Yeah. And you say, you tell me which one of these you are . Yeah, yeah. So they do their own diagnosis . Yes, they do their own diagnosis. We compare together. So they are going to do you out of a job, if they can do their own diagnosis with a machine laughter. They are not going to need violet any more, are they . Yeah many women do not go for the screening. It has been too expensive and because of a lack of education, many who do go feel its a waste of time if they get the all clear. Thats why violets job is to explain as well as test. I use this to check your cervix. Scans used to cost 40 to 50 over half a weeks wages. This scan costs 10. When a patient comes, you view their cervix and you have an opportunity to address them and to talk to them about Cervical Cancer. So, the hurdle that was previously there was education in relation to Cervical Cancer but now we have seen an improved attitude toward Cervical Cancer and increased screening. And with this, we can screen any woman, anywhere. The system isnt cheap. It is sold at 2000 a unit, but it has already seen an 80 increase in the number of women being scanned at this clinic over the last year. If kenyas new government decides to back the scheme, it could become a major weapon against a major killer. That was down in nairobi, and thats it for this week. Over the next couple of weeks we will give you the chance to re watch two of our favourite programmes from the year so far two india specials. We will be travelling across the country to meet the people working hard to change lives, save lives, and maybe, one day, discover new life. I hope you enjoy watching them as much as we enjoy making them. Do not forget we are on twitter and on facebook. Thank you for watching, we will see you soon. Whilst its been dry for many, it hasnt been dry for all of us. The showers are continuing for a while longer. Still some sunshine to end the day for many areas. A decent end the day for many areas. A decent end to the day but we keep the showers in the North East Of England and north of scotland. Generally overnight, the winds go light and skies will clear. It will turn chilly quickly, especially in the countryside. Wrap up well if you are heading outside to see the perseid meteor shower. Tomorrow night, theres more Cloud Spilling In from theres more Cloud Spilling In from the west. Not a great deal of cloud to begin the day on sunday. A few showers from the word go in scotland. North and central belt is where well see most of the showers. For the football tomorrow in the premier league, newcastle and old trafford, both games should be fine with sunshine. Most should be a drier day across northern england, more sunshine on the way here and most of wales missing too. Probably staying dry through the midlands. Any early showers fading away. Seeing the best of the temperatures 21 or 22 is likely for the final day of the world athletics hundredships. No sign of any rain. A decent end to the games. The rain holds off until the games. The rain holds off until the beginning of next week when well see heavier rain developing. At this stage fine and dry but well all get some rain which is gathering and turning heavy in the south west. That will push into the midlands, across east anglia up into northern england. The Weather System eases out of the way, leaving a few showers around perhaps on tuesday but still a very mixed week ahead, no sign of things settling down at all. Some sunshine at times, but we are going to see some spells of rain, notjust at are going to see some spells of rain, not just at the start are going to see some spells of rain, notjust at the start of are going to see some spells of rain, not just at the start of the week but later into wednesday, thursday and perhaps friday. This is bbc news. Im lukwesa burak. The headlines at 4pm a fresh warning for north korea from the us President Donald Trump says it will Regret It Fast if it continues to threaten america or its allies. They will be very safe. If anything happens to guam, theres going to be big, big trouble in north korea. Police have arrested a 27 year old man on suspicion of a double murder in golders green. Police, investigating the death of 83 year old peter wrighton, who was stabbed while walking his dog, have arrested a man in his 20s.
