This week spotting early signs of dementia, giving the banks the finger. Print, and man falls off skateboard. Theme music. Heres something that splits opinion, you either love these or you hate them, depending really on whether you ride one, or whether youve had a Close Encounter with one. These e scooters are powered by electric motors and that leads to something really interesting that not many people know. In the uk, these things are not legal on public roads and they are not legal on public pavements. So, although theyre getting more and more popular, and companies are hiring them out to ride on private lands like here at the Queen Elizabeth olympic park in london, where theyre geofenced and speed limited, the law varies hugely around the world. One of the issues is that these things can reach speeds of over 30 miles an hour, which is very cool, but also very dangerous, again, depending on your experiences with them. Not long ago, presenter Emily Hartridge died while riding an e scooter. It was the first fatal collision involving one in britain. There have been similarfatal cases around europe. In france, there have been three e scooter deaths in the last four months, and there have even been deaths in los angeles where these are completely legal. So, whether its e scooters, segways, one wheelers or e skateboards, theres a lot of confusion over the legality of these new modes of transport. As 0mar mehtab has been finding out. Here, at one of the busiest intersections in london, the metropolitan police are on the lookout for electrically powered scooters. These eco friendly and easy to ride vehicles have exploded in popularity and are rapidly transforming the make up of road traffic in cities around the world. However, as spencer pointed out earlier, with e scooters freely available to buy in stores, many people dont know that theyre actually illegal to ride on public streets. When i bought it online they should have told us that there are illegal to ride here. I mean, ijust spent £500 for nothing, basically. The problem is, these e scooters are electrically powered, so theyre classed as motor vehicles, which means you cant ride them on pavements or in bike lanes. And to ride them on roads, you need insurance, licensing, tax. Things you cant get for light e vehicles at the moment. And if you get caught . Well, in the uk, you could get up to six penalty points on your driving license and a fine of up to £300. Stops today was just about education, about letting them know you cant ride these things on the road, you cant use these things on the road. Recently, just down the road, there on rosemary avenue, was a fail to stop collision involving an e scooter and a i25cc scooter. I think it sends out the message that this needs to stop and the vehicles can only be used on private property or land. But, theres some confusion in the uk. The law states that personal transport devices powered by motors are prohibited for use on roads, pavements and cycle lanes. However, in the different categories listed, they dont specifically mention e skateboards, and that is catching some people out. This man was stopped by the police on his way to work, given a written warning, and while he got away without the hefty fine, he was informed that his e skateboad was illegal to ride. All the information i can find is that these ones are not illegal, like the electric skateboard is in the grey area, kind of, theres not really legislation that actually bans it. Until today, you know . And the police told me and i was like what . I said i bought this, it cost me a lot of money, ive been riding it for nearly five months now, no issues at all, no accident, no issues. And now from tomorrow, i think from this afternoon, i have to take underground, exactly. There will be queries with regards to e skateboards as well as e scooters and other types of powered transport but we recognise there was a growing trend with the use of e scooters around london and awareness that people werent necessarily educated to the fact that they are illegal to use on the roads and footpaths. So we have issued a number of fines and also seized some e scooters, but we are maintaining that message that we would like to educate the public first and foremost and sort of spread that message wide that they are actually illegal to ride on roads, on the pavement or in cycle lanes. However, the uk isnt the only country thats grappling with restrictions on light e vehicles. In paris, authorities have put down strict regulations. From next month there will be a 12 mph speed limit and a 135 euro fine for riding them on pavements. There is even a 35 euro fine for antisocial parking. But, for enthusiasts, these restrictions are the last thing they want to hear. So, ive come to an event in paris to find out what e skateboarders from around the world think about the regulations imposed on them. Theres tonnes of people here the are so many boards, some can go up to 50 mph i dont know why you need to go that fast. People can just ride and then get to work, go shopping, do their normal lives. It is just such a better way to do these things. We want to take cars off the road, we want to take pollution off the road and have electric vehicles in. Because this is the future. Regulations around the world are starting to tighten up. They will are limits to 20 kilometres per hour. Its really slow can you imagine . There are no bike lanes in the city, and in paris there are no bike lanes in every street, so it is very difficult. Going 20 kilometres per hour on the street . Your board can go up to what, 50 kilometres per hour . Thats crazy yeah. It is crazy, but you do have to have full protection and try it on a street without any cars and make sure its safe. In melbourne, for instance, which is a really big scene in australia, there is a policeman in that electric skateboard riders group, he cruises with everyone and there are no problems. Because what he says is as long as youre a reasonable citizen, youre behaving yourself, you wear protection, youre not causing problems, nobody cares. Its safe, and everyones happy. So how safe are they . It cant be that hard to ride one of these, right . Ill put a little bit of throttle on. 0h, are you doing that . Im doing that. 0k. Ahaha no, no, no. No aaah and as you can see, it isnt the easiest thing to use. And, even seasoned riders can have trouble staying on. This is the thing. People can just get a board, you know, you dont need a license, you dont need insurance. So then does that make that safe enough to drive out in the road, or on the pavement . Do need a little bit of training first or something . 0rjust a piece of paper to say, yes, i can operate this thing safely. Because then otherwise youre gonna crash, you know, into something or someone. Back in the uk, we contacted the department for transport and they told us they are actively examining how these light electronic vehicles can be regulated for safe use on the roads. But, for now, they are still illegal. So, this is michael. Hes the one who first introduced me to e skateboards and he is a part of the community. So, that is the official line of the met, theyre illegal to use on the roads and pavements. What do you think of that . I mean, theyre not wrong. As a mechanically propelled vehicle they are illegal on the road because we dont have things like insurance or licensees for these devices. The problem is, there is no legislation at the moment for that, so we cant get insurance, we cant get licenses, and at the exponential rate the boards are being used, legislation needs to be put in place so we can get insurance. Its not like we dont want to, its just that we cant. If we can legally ride on the roads with every other road user, whatever the cost, if its legal, id say go for it. Right. Michael, thanks a lot for chatting with me. Appreciate it. Now, this is the bbc, its private land. So, im out of here hello and welcome to the week in tech. Its the week that Face Recognition Software was found being used in londons kings cross. Described as alarming by some, Property Developer argent says it uses the tech to ensure Public Safety but did not reveal further details. Meanwhile, just a few hundred miles outside of hollywood, witness nasajpls lemur climbing robot hard at work. This 16 fingered cybernaut has been scaling the steep walls of californias death valley. And from outer space to inner self, meet mindar, the robotic buddhist priest. Yes, Douglas Adams was right. The electric monk now exists and is available for sermons at kyotos Kodaiji Temple injapan. Based on kannon, goddess of mercy, lord of compassion, its hoped the chilled out android will help attract more people to the essence of buddhist teachings. Ah, some gentle meditation, a great way to prepare for a heavy night raving with a dj thats truly out of this world orbiting the earth at about 17,000 mph. Italian astronaut Luca Parmitano played a live set from the International Space station to a cruise ship full of clubbers. The first dj in orbit took lessons prior to going into space, saying he wanted to celebrate the common language of music. Imagine being there when the bass dropped from about 250 miles. Right, lets talk money now, or more specifically, plastic. Now, the last Time Technology touch one of these things was more than ten years ago when they made them contactless. Wave and pay uses nfc or Near Field Communication technology and its really convenient, but not exactly secure. Not if you have your wallet nicked. Anyway, thats why they limit Contactless Payments to £30 or roughly the equivalent in other currencies. But that limit could be extended by quite a chunk if a new security feature is added. Dan simmons has been invited to test the uks first debit card that can read your fingerprint. Its a big moment in the world of money. Natwest and rbs are launching this although the real life ones will probably be smaller. And they should help wave goodbye to fraud. What were learning from customers is they want experiences to be simple and easy. This means they dont have to remember their pin, it means from a safety and security perspective, they dont need to worry about standing at a cash point and someone looking over their shoulder and seeing what their pin is. And we think customers are really going to the experience. Could they not get an imprint . No, its not csi, it doesnt work that way. It doesnt . 0k. So, a photograph . Nope. If i go hi, theyjust go, oh, yes, excellent theres enough pixels there and nick that . That wont work. On a glass, you know, like Police Evidence kind of things . The powder . No, that doesnt work. No . Nothing . No, sorry, your television dreams are shattered. If something goes wrong and i find that somebodys got my money that shouldnt have my money, will you give it back to me . What you can always do is block your card with one phone call. Is that a yes or a no, georgina . We review all Customer Experiences on a case by case basis. Right. Its arrived. Ive got a sort of of like a card reader and the card itself. Im going to need that Little Black Box to kind of register my thumbprint on the fingerprint reader. Ive been invited to take part in a three month trial. The small battery in the reader is enough to power the card. After seeing my thumb from five different angles, its happy its got my print. Now, of course google and apple pay systems using our mobile phones linked to a debit card and credit card offer similar biometric security for payments. But your phone costs a lot more, needs to be charged and its a lot bigger. My new card is no thicker than a standard debit card. A strip down of it shows whats going on. 0n the right is the fingerprint reader, theres no battery inside, instead an inductive loop shown in red acts as an aerial for the card to receive power from the card terminal. The six dots at the top are the programming port. And its here, in the microcontroller, when my fingerprint is stored and verified. All on the card, so our biometric data never leaves our hands. A coffee, please. Data never leaves our hands. Now using the card is pretty much as easy as it is at the moment, except you have got to put your thumb, or whatever finger youve registered, over the golden box, so it can recognise it when you make the payment. A green light flashes to show alls 0k, and thats my plastic is not in some trickster tv producers mitts. Now the other big bonus i found is my new spending limit. Normally, Contactless Payments cap out at £30. But this allows me to spend up to £100 because of the additional security, and im told that by the time it comes to market, that limit could be limitless, which means i could get my weekly shopping, fill up my car, and buy a bikejust with a tap of my card. So knowing all that will the card be secure . Gemalto is behind the tech. The actual sensor we use is dynamic, which means each time it reads your fingerprint it needs to be a 98 99 match. If there is a slight variation, a micro slash on your finger it will take that into account, so next time it knows that micro slash will be there. But does it then allow for someone with a similar fingerprint to get into the system . No, not at all, the variation is so small, there is not two people that would be within that level of variation. This would be the biggest change to payment cards for a decade, if the banks back it. So the uk based rbs and natwest trial finished on wednesday. You met Georgina Buckley in dans film. Georgina, the trial has now finished, what have you learned . We had great engagement from customers which was the purpose of the trial, they really enjoyed the look and feel of the card, and the green led lights when it works, that was really positive from customers. Love a flashing light. And also some of the retailers Technology Needs upgraded, essentially to take biometric authentication which we hadnt expected, and that was a really good learning. Making these cards obviously costs a little bit extra, and you asked customers whether they would be willing to pay for these cards. We did, we had mixed results from customers, so some said they would be happy to pay a fee to have that increased authentication, and others werent. Hopefully as we are able to roll it out more widely the average cost to produce them will come down, but we just have to see how that goes. Assuming it all works, what is the next step of the plan . We are now going to launch out biometric for credit cards, we will launch that pilot next month, and slightly different experience, we are not going to put a limit on it, so you would be able to use your biometric fingerprint up to the limit of your credit card. Slightly different and we should get different feedback from customers, and again learn the positives, learn the negatives and then use the pilot to fuel our innovation portfolio. And when can we expect these cards to be deployed for everyone to use . Well, im hoping we can process the learnings later this year, and then look at a broader rollout next year. There are currently an estimated 850,000 People Living with dementia in the uk. And while the most commonly assumed symptom is forgetfulness, spatial awareness, perception and the ability to read faces are also hugely affected. Lara lewington has been looking at some technological approaches to better understand this condition. For those with a parent who has had what is known as frontal lobe dementia, there is a 50 50 chance of them developing it too. But a new study hopes to offer some promise for those at high risk by gamifying brain analysis, and an earlier diagnosis would mean the chance to try and treat the condition sooner. Well, Early Detection of dementia is really important because what were beginning to understand is that by the time people start to notice the symptoms of dementia like memory loss, there might actually be quite extensive changes in the brain there. This app is actually developed for 30 and 40 year olds to use, to help diagnose the possible early stages of dementia. I have to say, i was a little bit nervous about doing this, because i was worried i was going to find out somthing i didnt want to. But it seems that because it is still very early days for the trial, right now this will alljust come down to some anonymised data, so i wont actually get that answer back. But the questions are a mixture of whether you will get it right, the time you do it in, or whether you are going to be able to finish each section in time. And it is from that that the decision as to whether you already have early stage dementia or not can be made. It is a series of 18 different games which test effectively different cognitive functions. It might be executive function, socialfunction, visio spatial, language, arithmetic, so the tests are designed to test different areas of the brain. You also get lots of simple benefits such as being able to measure timings and accuracy of when people answer things and how they answer things. So by being much more sensitive than a paper based testing system, again, you have got a hope of treating things. This is part of a year long study. The test is taken every three months, as well as a paper test at the start and finish. 20 of those taking part already have symptoms. The others are those with a 50 chance of developing frontal lobe dementia. If we can show efficacy in the wider dementia population, then that might be something that can be used at the front line by gps, but of course its very important to do that alongside genetic counselling and all the other implications of a diagnosis that come with it. I have real hopes for the ignite app, that can help people with frontal temporal dementia by measuring sensitive changes in their cognition and thinking that go with the early stages of the disease, and as part of a wider study, that can be used to measure the effects of new and novel types of treatment and drugs to see if they are actually having a benefit in the performance on these type of tests and apps. And of course it is notjust the patient whose life is affected. For loved ones it can be a heartbreaking and frustrating journey. And often one that is hard to comprehend. This is a Vr Experience that aims to put you in the position of the person who has dementia, to be able to help you provide a bit more empathy for a loved one or simply understand more about the condition. Use this voice. My daughter is talking to me, but the voice is saying i cant hear her. I feel very disconnected from her and im not sure if that is a deliberate part of the experience orjust because she is a person in virtual reality. Bob will be wanting his lunch at one. Why is she just chatting on the phone . Shes not paying me proper attention. Shes agitated and talking about dad again. Is she talking about me . I think this is probably how not to treat a relative with dementia. No, i dont think its time to be thinking about a home. 0h, goodness, apparently i have misheard and i want to go home, i dont feel safe here. Its all become a bit muddled. Well, it certainly stirs up quite a reaction. I felt frustrated, a bit confused at times, anxious and actually quite hurt by the way i was being dealt with by my daughter. So i think there is quite a lot going on in the experience to think about, but i really could do with the opinion of someone who knows more than i do. Tim has worked in Dementia Care for many years, and knows only too well the day to day challenges and the importance of dealing with them sensitively. Illjust pop this kettle on the hob. It wont be long now. You can see the steam. Whats that noise . Dementia is not just about losing your memory, it can affect your perception as well. So this vr app is about keeping track of a particular sequence the reality is as we looked at some of those rooms, some of the floors are shiny, and if your perception has been affected that could look like a wet floor. When we look like a patterned carpet, that might look like perhaps animals or shapes moving in the floor. When we were the gentleman in the cafe with the daughter and actually seeing that he was not recognising the timing, he thought he was going home for lunch, and then she was on the phone and ignoring him and speaking about him as if he wasnt there, thats the wrong way to do it. You need to be with the person they are there, they are a whole person, see the person, not the dementia. It really brought the experience to life, but importantly actually it showed what to do sometimes. What does this note say . For a condition so widespread, bringing home the reality could be really helpful. And while it may take decades to see whether early diagnosis will make a difference to the outcome, the research is a positive step in the right direction. Providing hope for many thousands of people affected by something so devastating. Two red, one blue. Thats it for now. For the next couple of weeks were going to be recharging our batteries, so we will give you the chance to see again a couple of our favourite recent shows. We will still be here though, on the end of youtube, facebook, instagram and twitter, at bbcclick. So feel free to get in touch. Thanks for watching and we will see you soon. Hello. Well, for some of us another mixed bag today. A bit like yesterday, a mixture of sunshine and showers expected across scotland, Northern Ireland, but also one or two have been affecting southern areas of the uk as well. If you were an early bird it was pretty overcast across the south. We had a little bit of light rain that weather front is now moving away towards the east. However in scotland and Northern Ireland we are right in the centre of that low pressure here so hence the showers will be most frequent. And this low pressure is still going to be with us tomorrow. Here is the radar is showing us where it has been raining. You can see these lines of showers, these streaks rapping into the low and also one or two showers further south as well. But i think predominantly this afternoon wales and at least the southern half of england enjoying a mostly sunny day whereas in the north showe the clouds and the showers, will be a little bit more frequent. So catching one in belfast, glasgow, i think more likely there. 16, 18 degrees in the north. 22 expected in london. Not much change through tonight. You get a sense that the low pressure is still with us. You can see that the winds rapping into that low with the showers circling it. The further away you are from the low the more lengthy the clear spells will be, certainly in the south and the east. 0vernight lows, 12 in london. Well match that in glasgow and edinburgh. High pressure is way towards the south west of us. It wants to build in but not in a hurry. In fact later in the week it could but for monday we are still anticipating that low pressure to send showers into North Western parts of the country. You see the wind direction there mostly coming in from the north west. It is a cool source, hence those temperatures are not particularly exciting, around 16 there and only 1a in stornoway. But the anticipation is by the time we get to tuesday the wind will start to shift direction. You can see it is coming in more from the south west. That is a warmer source. Obviously the warm air is in the south so that is pulling up that warmth towards us. But that does mean cloud and some spots of rain across the west with a weather front here on tuesday. But the thinking is, and its becoming increasingly likely, that perhaps towards the end of the week and into the weekend things will be warming up across southern and central parts of the uk. So, fingers crossed, warmer weather on the way. Bye bye. This is bbc news im shaun ley.
