in monza. now on bbc news: click — this week a look at how technology is being used to look after the elderly. this week: robot nurses. robot rabbits. and disco—dancing aliens. it's technology that will put a smile on your face — literally. believe it or not, modern nursing as we know it only dates back to the 1800s, to the time of florence nightingale and other pioneers.

the royal college of nursing here in london is now in its 101st year. for all the life—saving technology that we've seen, the actual act of nursing itself is one relationship that so far has remained uniquely human. but our population is ageing. 20% ofjapan is over the age of 60. and in the uk, a quarter will be over 65 by 2045. this all means that the pressures on nursing are increasing, and looking after elderly people is becoming a pressing issue around the world. kat hawkins travelled to helsinki, in finland, to discover whether one of these could become the new one of these. i'm here in helsinki, visiting the home of marja roth sopanen. hello!

hello, how are you? nice to meet you! nice meeting you! she's an ex—air hostess, who likes to keep active at the age of 73. look at the hat as well! that was ages ago! but after a skiing accident a few years ago, she developed epilepsy. ifell down, backwards, hit my head. i was unconscious for a little while, then got up and skied, and that's when it started. her epilepsy means she needs daily medication and that her family, who live in new york, want to make sure she's 0k. they get this reassurance from her daily nursing visit — over on the living room table. do you think that this is as good as a nursing visit? it's better because they see, actually physical, see me, and then i don't have to wait for somebody to come. they want to check basically that i, ask basically if i took my pill, and... and just see how you are? howi... yeah. face, actually, to see the picture, to see that i'm 0k.

at the other end of the line is tuomo kuivamaki. he's one of the nurses here in helsinki's first virtual nursing centre. here, teams of trained nurses each make up to 50 video calls per day to people around the city who need support. so you've still got that kind of real human... yeah, yeah. and especially some of the older customers, that's like a highlight of the day for them, to have sort of a small chat with a friendly nurse! the hope is that this will cut down on the number of home visits that nurses have to do to people who don't need physical support, freeing up more time for those that do. the software itself, called video visit, works much like any video call. so while the tech isn't that new, helsinki's unique in how wisely the government is using it, and that can mean big savings for them. an in—person nursing visit can cost around a0 euros, but this new type of checkup costs as little as five. and what really comes across watching this call

is that they do have a relationship. they're chatting away. and itjust shows that that nursing element, that real human connection, is still there, even though it's a video call. people do hesitate at technology, and especially in nursing. we have virtual home care. we are actually taking care of people. it's scary that the robots are coming and taking ourjobs. actually, the robots are in here already, but they are easing ourjob and actually giving us the freedom to focus on people who actually need our physical help. helsinki isn't the only place trying to keep people happy in their own homes for longer. at the bristol robotics lab in the uk, a mock house is being used to predict what social care of the future might look like. patients in their homes, but supported by a host of robots and smart devices. the fridge is open. pepper has automatically recognised that the fridge has now opened. there's some chicken soup.

you could heat that in the microwave. there's some chicken soup, i can heat that in the microwave. as well as recognising certain sensors around the house, pepper is designed for other functions, aimed at keeping people in their own homes, such as physiotherapy exercises. critics argue that robots can never replace the human interaction between carer and patient. 0thers point to their ability to go wrong. but if robots mean that people can live independently in their own homes for longer, then it might be we see more of them knocking around our kitchens in the future. that was kat. now, medical technologies, of course, are improving across—the—board. one example is the use of wearable technology for tracking facial muscles. now, this can be transformative for people with conditions like facial palsy, parkinson's and autism — allowing them

to control devices remotely, or even just smile naturally. we asked three volunteers to try out some of the latest tech on offer. my name is bethan robertson—smith and i'm doing my daily routine. it's a series of exercises to flex the muscles in my face. in 2008, when i was at university studying to be a veterinary nurse, i had a serious car accident. i had a fractured skull, an acquired brain injury, and i was left with facial palsy — also known as facial paralysis. it meant that every one of the a0 muscles that gave expression in my face had been paralysed. years later, i had an operation that allowed me to smile like a mona lisa, using just two of the chewing muscles that were unaffected by the accident. it's very hard to know exactly what muscles i need to move to help me smile. i came down to brighton today to try

out a new piece of technology that's gonna help people like myself, who've got facial palsy. one of the surgeons who operated on me is part of a team of experts developing technologies with sensors to read the muscle activities of people with facial paralysis. so, when you were first diagnosed, you had an examination called the needle emg, where the needle was put into the skin, into the muscles, to read the tiny electrical signals that the muscles emanate. with this technology, what we're using is these sensors that are noninvasive. so the same kind of reading, but without the pain, like none of the...? that's right. you have some degree of crossover between the muscles and that's why you need the machine learning and the artificial intelligence to interpret which muscle is activating. i'm sarah healey and, 30 years ago, i had a brain tumour. try to raise both eyebrows symmetrically. raise them both together. together... and relax.

the operation to take it out left me with paralysis on the right—hand side of my face. 0k. now smile with lips together. i'm certainly not alone, as there are about 100,000 people in the uk who have had facial paralysis for years. so each one of these dots represents the position on your face. 0k. and so, for example, if you were to try and do a left—sided smile... just smile. and relax. and the darker the red, the bigger the signal. so because my left side is better and stronger... that's right. ..it‘s showing up as stronger on the screen. that's right. this is great because for the first time, i'm getting accurate information about what is going on with my face. i tend to overwork this side of my face, so this really is giving me feedback that i have to dampen down the movements i don't want, and this isjust so good at doing that. i sort of try and practise in front of a mirror.

it's not quite as subtle as this, is it? and also, i'm not that keen on looking in mirrors, to be quite honest. but it doesn't end there. this headset takes all the information from sensors — just like in the goggles — but now translates it into real—time expressions on a 3—d cartoon. yeah, so i'm trying really hard to make her do a full smile... yes. but it feels funny on my face. yes. doing it to a mirror, you kind of tell yourself what it looks like. that's right. whereas she is like, oh, no, that's not what it looks like. my name's george dowell, i'm the owner of worthing football club. a lot on my day—to—day work involves using a computer and it can often be quite time consuming. before i had my car accident, in 2010, i was a player for the club and on my way up. the accident left me with a broken spine and ten months in hospital.

it was obviously a very tough time for me, but after a lot of rehab, i decided i wasn't gonna give up on football and i used my compensation pay—off from the accident to buy the club i used to play for. how are you doing, you all right? nice to see you. and you. so there are quite a few companies now looking to see whether they can use vr as a new work space. yeah. so by using this type of technology to sort of allow you to type much faster and interact with other people. if you thought it was quite funny, you can give it an eye wink. or if you didn't like it, you can now do a frown

and it'll do a frowny face. there you go. he looks grumpy, doesn't he? with this new headset, i should be able to control the keyboard and options using a wink or a frown, which will open up a whole new world for me. yeah, it's very responsive. you're really slick on that now! it might sound strange to say, but for the first time since my accident, i'm able to see what my smile actually looks like. not to make it sound like, i dunno, a strange way, but you're kind of doing it with somebody else. yes. and it's not such a lonely thing. my biggest aim for this would be to be able to help me smile symmetrically. that's been one of my aims for the last 30 years. welcome to the ‘week in tech‘. it was the week instagram admitted a flaw in its systems revealed a number of celebrities‘ phone numbers and e—mail addresses to cyber attackers. nasa announced a replacement for the space shuttle could be one step closer to happening. it's called dream chaser and it's being developed by a private company. and pizza—delivery drivers could be out of a job if domino's and ford's autonomous car delivery service trials take off in the usa. a german university has scooped top prize spacex's hyperloop pod design competition, with a pod that reached a top speed of 20! mph. but their trial has been topped

by elon musk‘s tesla pod, which has been used to give the students‘ efforts a push—start, recording a speed of 220 mph. and uber took steps to change its public image with the arrival of a new ceo, dara khosrowshahi. the firm‘s made a u—turn on its policy allowing it to track users for five minutes afterfinishing a ride. the update, due to be rolled out this week, means tracking ends immediately once a ride is finished. and finally, google announced it would replace its augmented reality effort tango with one called arcore. the technology will first be available on the samsung galaxy s8 and google pixel phone. not to be outdone, apple gathered developers together to show off some of the new apps soon to be available thanks to its new ar kit — from ikea‘s app that lets you place furniture virtually in your home, all the way to one very hungry caterpillar. we‘ve now seen robots doing many things, but the idea of them

keeping us company is, for many, still quite hard to comprehend, but that‘s something a few companies are hoping to overcome. meet miro. whilst the hardware is finished, the software is still being worked on, but the aim is to create a cute companion for the elderly which will also be able to provide some practicalfunctions. now, they‘re all made possible by a host of sensors which are built in here. we‘ve got two directional microphones, so we can tell where the sound‘s coming from, two cameras here in the eyes that are going to be tracking emotions, a sonar sensor here in the nose, which should stop the creature from bumping into anything. there are also cliff sensors here, so it shouldn‘t fall off the edge of anything. and light sensors all around can tell whether it‘s night or day, so it‘ll act appropriately —

because if you give it a stroke, you can see just how excited it can actually get. the bot is already available to developers, with a consumer unit expected later this year. the aim is that by then, it‘ll feature facial recognition, voice control, c02 smoke and temperature sensors and a constant record function. long—term, the hope is it‘ll become a therapy robot for those with a variety of conditions, including autism and dementia. so whilst the dog, rabbit — or is it a cow? — keeps an eye on you, it‘s also gonna be synching up to its companion app and also this bracelet, which can sense falls. now, it‘ll keep track of all that data and if anything is out of the ordinary, if a user was to break their routine, then it could make chosen relatives or friends aware. but whilst part of its role is caring, it‘s also intended to provide emotional engagement.

it‘s definitely watching. a huge amount of effort has gone into the body language — the blinking, the way the head moves and the tail moves, and the things like that. and that is really as important as the other functionality. and the trouble is with a lot of these humanoid robots, they‘re not. and, you know, they can‘t behave like a human. they can sort of wave their arms around in a mechanical manner, but they don‘t have that what the japanese call kawaii, or cuteness. and when i started working in robotics, i realised that there was a real opportunity to make, you know, mechanical devices emotionally engaging. this isn‘t the only device in this space. parihug has just completed a successful crowdfunding campaign and aims to provide long—distance cuddles. yes, long—distance cuddles! the idea is that the wi—fi connected

toy can give a hug via another of the creatures to loved—ones you miss — especially parents away from kids. of course, none of this is about robots replacing the need for real pets or human company, but if they could offer a little bit of support when it‘s needed, then how can we really think that‘s an issue? night—night! huh... hey, how you doing? you all right? yeah, man, i‘lljoin you in a bit. have you heard the one about the alien who walks into a bar and says... mmm, i‘ll have a blue milk. hmm... put it in a glass... now, as impressive as this bizarre setup looks, these motion—capture suits and stages are actually the standard way that industrial light & magic uses actors to give realistic movements to computer—generated

principal characters. thank you very much. no worries! you were very frightening. ah, good. i mean, he‘s a nice dad, i think, jalien. even the fact that jalien here is being rendered in real time for the director to see during the performance is not in itself new. i remember back in, i think it was 2007, i went to ilm in san francisco. i wore the ball suit and they turned me into a green alien, live right there in the studio, and i was absolutely blown away by it. ten years on, just look at this guy! hey, check me out! hi, man. hey. what is brand—new here is the live rendering ofjethro‘s facial expressions. now, although facial capture has been a thing for a few years, so far, the director hasn‘t been able to see the results on the character‘s face during the recording. you know, our big focus was around the face and being able to capture

the face at the same time as the body. and we can determine what expressions are happening each frame, and then directors can see that live and make decisions on if the character is working as a character, whether his expressions need to change in terms of the model. in order to process an actor‘s expressions quickly enough, only one face cam and a few mo—cap dots are used. this simplified live data is then compared to a higher resolution 3—d capture of the actor‘s face that‘s taken beforehand on a rig called... the medusa. now, unlike other facial—ca ptu re systems we‘ve seen which take still images of the actor‘s face, here they‘re shooting video of my face moving into and out of each emotion. that means that the facial recreation and the animations will look a lot more natural. the live, high—quality rendering of both face and body can also become a magic mirror on sets to help the actor to get into the part.

so i feel like this is how i get to know who i am, what my limitations are, what my body is, what my girth is, how it moves, how it sort of doesn‘t move. you see i have a nice heavy arm. whether i have to consider that weight. and i guess it really does make you move differently when you‘re on set, if you‘re playing a half—tonne alien, to you being a svelte young man. it totally does, as long as i engage my imagination. because if you can see, i‘m totally beautifully... he laughs. you know, in a way that jalien can‘t, my wet suit moves in a way that maybe that arm and that outfit doesn‘t move. it‘s good showing you my, er, my stuff. so here, they‘re bringing digital characters to life for the director and the performers to work with, but there are ways to bring digital characters to entire audiences live on stage. in fact, it‘s something we tried out

on our click live show at the end of last year. so when we heard that the nederlands dans theater was dabbling in this kind of stuff too, we sent nick kwek — click‘s finest ballet dancer — to investigate. welcome to the world of modern dance — conservative, traditional, disciplined. but at the same time, innovative, rebellious, perpetually striving to push the envelope. today, choreographers and dancers of ndt are working with a new medium for artistic expression. they‘re taking two excerpts from their show called stop motion and adapting it to include holographic projections. it's almost an imax—type experience, without the need for glasses, you know? every detail has been

carefully crafted. they‘re projecting a falling white giant and dust onto a black backdrop, playing with the themes of light and dark and destruction. technology needs to embrace the art, but not with sticking out all by itself. it needs to help. it's like a glove to the art, to the expression. the holographic illusion is created with the help of two very high—end projectors and a special lightweight mesh screen. by playing out videos on the front mesh and back wall, it creates an optical illusion of 3—d depth. for the performers, it‘s actually a really good rig to work with because they can see the projections on this side whilst they‘re on stage performing. with other systems, you don‘t really get that same wall... it‘s really realistic, actually! also handy if you fancy giving a very expensive powerpoint presentation, as one of these novo line rigs costs anywhere from 15 grand for a week‘s rental.

we wanted to have a full space for a dancer, a performer, a ceo to talk. we wanted that you could touch it. the other system, you can't touch it because it's smeared, it's a fragile, reflective surface. this, you can wrap around, we could create curves with it. and of course, it can go to massive sizes. and to take the whole thing even further, they‘re introducing real—life flour to complement the virtual stuff, blending the boundaries between real and virtual. sort of. we‘ve got a bit of technical difficulty. but luckily, paul‘s in his pants. so, a man in pants will surely save the day! problem solved, dancer into position, stand by lighting, music, cue projection... and action! cheering and applause.

actually, instead of complementing the effect, i think it actually detracted from it a little bit. yep. especially when the flour went onto the back wall. yep, yep. because then you go, well, that‘s now totally fake. it's no magic. creating an extra audiovisual experience, though, adds to the complexity of live performance. it‘s notjust the type of visuals, it‘s the scale, the brightness, how the lighting interacts with the mesh, how it blends with the real—life action on stage. but, no pain, no gain. to be artistic with technology, it's not easy and it's a lot of experiences, and a lot of mistakes to see, so what do we want to do? so it needs time. i think this ballet, for example, has the beauty itself. mmm. you don't need this. mmm. well, that‘s it for this week. don‘t forget, we live

on facebook and on twitter... thanks for watching. thanks for having us at your place, jalien. hey, no worries, man. hmm... now, get out of here! yeah. hmm... out! move, scoot, mm! huh... jackass, huh? yeah. i‘ve gotta go, bye. huh. this week all the weather is coming from the atlantic so very changeable. today we have seen a bank of cloud quite low cloud producing this rain and drizzle and

its moving very slowly east. we find this is actually becoming lighter and more patchy, a bit more of it heading towards eastern coasts. we will be left with a lot of low cloud around overnight, as a result you can see quite a bit of hill fog but it‘s quite warm air so temperatures 14, 15 degrees it‘s quite warm air so temperatures 14,15 degrees minimum for many parts of the country. heading to tomorrow, for the start of the week it‘s quite a grey and gloomy start, perhaps a bit brighter across east anglia where we are missing most of the rain but still some low cloud, rain and drizzle across northern england, whilst many eastern parts of scotla nd england, whilst many eastern parts of scotland and also northern ireland start dry there is a band of rangers waiting in the north—west and it‘s going to be accompanied by stronger wind ‘s. may eventually

clear from western parts of northern ireland, it may brighten up a touch in england and wales after a dull and misty start but there was be drizzly showers but remember it‘s warm and muddy so even with the cloud 1920 bit of sunshine in central and southern parts of england and 2223 degrees possible. still have a weather front on the scene and it peps up the rain a little bit overnight, into tuesday across the south—west, wales, northern england, the worst of it in the morning heading out into the north sea. the sum rain around pushing through the midlands. they ta ke pushing through the midlands. they take time to clear, otherwise brightens up, more fresh air, cooler air, sunshine and a few showers perhaps towards the north—west. as we head towards the middle part of the week it‘s all coming in from the atlantic, right away from the other side of the atlantic, westerly winds, showers, particularly towards the west and north—west, brighter skies and sunshine in the east. those temperatures are what we will find to the rest of the week which

are find to the rest of the week which a re pretty find to the rest of the week which are pretty normal, we will keep those westerly winds going, rain showers, wet and windy to end the week. this is bbc news. the headlines at four: north korea says it has successfully tested a hydrogen bomb capable of being fitted to an inter—continental missile. there‘s been worldwide condemnation. experts warn that north korea‘s nuclear capability is advancing rapidly. president trump tweets that north korea‘s words and actions continue to be very hostile and dangerous to the united states while theresa may has called it a "reckless and unacceptable further threat". pro—eu conservative mps are urged by theresa may to unite, ahead of a debate of the government‘s brexit repeal bill next week. the brexit secretary said the eu is making itself look silly by insisting negotiations with britain aren‘t making progress. the
