hello. shared with members of the this is bbc community. two of those are in a critical condition. news. i'm ben bland. you're watching the headlines: bbc news. a man has appeared in court in new zealand to be charged we arejust we are just hearing the new zealand with murder, following the shooting prime minister deliver a statement of 49 people at two mosques in christchurch. on that shooting, that terrorist brenton tarrant, who's 28, attack that happened in did not enter a plea. further charges are expected to be christchurch. we were just brought against him. the police commissioner has hoping to reassured locals that there is no go to jacinda ardern, the new zealand prime minister, who has been known imminent threat of another similar attack, but says delivering a statement, but it does appear there has been a technical they will problem and we were not able to hear remain vigilant. what she had to say, but she has a total of four people were taken beenin into custody on friday, what she had to say, but she has been in christchurch talking about one of whom was released that terror attack. a short time later. around a0 people remain in hospital — some in a critical condition. 49 people have families have an agonising wait for news as the list of missing died and a number of peep will people grows. syrian refugees are thought i still injured. —— to be among the dead. across the world, thousands of people have come people are still together in support of the muslims killed. injured. and of course the many have said prayers conversation has been around gun in a show of solidarity laws as well. and police in some countries have increased patrols at mosques. our top stories: new zealand police say they're not looking for any further suspects now on bbc news, it's time in the killing of 49 people in christchurch on friday, for click, and a special programme but

from one of the most cutting edge tech nations in the world — are japan. remaining vigilant. this week, we are we will be highly injapan to vigilant, high lea p we will be highly vigilant, high leap present, highly visible, to find ensure that if there the fascinating, the ferocious and is anyone out the fascinating, the ferocious and there wanting to commit harm, the famous, fiction. that we can intervene. —— highly present. the main suspect in the killing, brendan tarrant, has been charged with murder. further charges are expected. 11 people remain in a critical condition —— if fictional. in christchurch hospital following the shooting at two mosques. two children are also among the injured. the head of surgery says some of the victims will need lengthy treatment. it is amazing to think that next year, this place will play host to the greatest show on earth. by the time twenty20 rolls

around, it would have been 56 years since japan last hosted the olympic games. —— 2020. backin hosted the olympic games. —— 2020. back in 1964, they use the event to signal of the nation following the disruption of the second world war, then the focus was japan's economic and technological explosion. now, japan once again wants to show the world that it is still leading the way in innovation. but with the country's explosive growth spurt now in the past and an ageing population on the horizon, the story this time might not be so simple. it is playing heavily on its image as the land of the robots, but finds itself as just land of the robots, but finds itself asjust one of land of the robots, but finds itself as just one of many countries researching all of the other big tech areas, including 5g, ak broadcasting and self driving cars.

an transport is the subject of this broadcast by entity to como. it is trying to predict traffic congestion by tracking phone uses‘s movements throughout the day. —— 8k. —— ntt docomo. ntt docomo knows the home address of each of its subscribers and also knows pretty accurately where any of their phones are at any time. it has used in artificial intelligence to watch how and where they travel to out the day and also how and when they return home at night. it can now predict where traffic congestion will occur in the evening based on where everyone is during the day, and it is hoped that the artificial intelligence may also be able to hope that our cope with the different traffic flows associated with the olympic.

the system we have developed contract use a population in real—time, increased social activity occurs because people move from one place to another. based on this concept, we are developing some new services using this data. for example, ai taxis. now with so many visitors flooding into japan, safety is paramount and for the first time, the olympics will be using facial recognition to ensure speedy identification. paul carter has been defined out more. at next year's olympic and paralympic games, tokyo is expecting millions of spectators to pack into the city for its festivals of sports, among that number will be over 300,000 accredited people, including athletes, volunteers, media and other staff, all needing access to restricted areas. developed by japanese firm nec and based on their engine called neo face, they

claim the system is 99% accurate and almost immediate, but how well does it work in practice? i have come for a demonstration to find out. in orderfor a facial a demonstration to find out. in order for a facial recognition system to work, needs a record of yourface. system to work, needs a record of your face. unfortunately for this system, it is now going to have to get a record of this ugly mug. —— 110w get a record of this ugly mug. —— now unfortunately. translation: the system recognises your eyes, face, the size of your face and other features, using hundreds and hundreds of points, and then much is that with the photos that are registered on the cards. now that the system has a record of my face, all i need is this card, let's see if it works. good to go. but you can't talk facial recognition without concerns about privacy. i asked a spokesman for the organisers what they would do with all those faces. the personal data, corrected

through the application process, will be securely guarded. —— collected. and it will be destroyed in the most appropriate way once games is over. known anyone tells you things are going to be more efficient and in this case near instantaneous, i am always a little bit suspicious but i have to say the thing that is most impressive about the system is that in the dozen or so the system is that in the dozen or so times i have tried it, it has recognised me pretty much instantly every single time and it is seeing my face and a wide variety of angles and it still seems to work, so i think in this case those claims actually hold up. —— now. but of course, controlled demos are very different from real—world applications, the proof ultimately in the killing. that was paul

carter, and someone else who has been having her face carter, and someone else who has been having herface mapped recently is kate russell, he went in search of japan's latest online craze. hire everyone. —— hi everyone. welcome to a new age of virtually tubers, animated characters driven by real people to entertain and inform. hyori works for a government department responsible for promoting tourism and business in a region. live streaming channels have become incredibly popular, but they usually feature people. hyori already has 96,000 subscribers and it seems japan has really taken to the phenomenon. almost 2.5 million people subscribe to watch kazuma ai.

then there is the slightly disturbing case of a horse called. i am at spy studios in the back streets of tokyo and they have kindly agreed to give me the full virtual youtube treatment. all of these cameras around here are going to understand where my body is in the 3d space that we are in and that will translate to the avatar moving, and then this camera is going to ca ptu re and then this camera is going to capture my facial expressions and translate that to the avatar as well. so my transformation is about to ta ke well. so my transformation is about to take place. uam. —— uam. hello, my name is natsu. the beauty of this

system is that you can be any character that you want and the application will mirror your movement in real—time, allowing live performance and view interaction online. —— i am. performance and view interaction online. -- i am. translation: since the end of 2017, vtubers have become more and more popular. we decided to use this idea because it would be compatible with our viewers. although vtubers are popular in japan, this london based channel was among the very first. hello, bbc click. i have been making youtube video since 2011. her vlogs are remarkably human. in fact, she seems com pletely remarkably human. in fact, she seems completely unaware she is in animation. but this cgi clip took 20 hours to produce. using motion ca ptu re hours to produce. using motion capture allows the modern day vtuber to deliver a lot more content in the

same amount of time. translation: using what we already have, we can move them in real—time. activating the gloves is what is new about the system. it is incredibly detailed, the movement. i mean literally wiggling my little fingers, do a little circle with my fingers. so what is next? hello we would like more people to know about it. we would also like to put her on esports and promoter not only to the japanese, but also to the international audience. the world is so crazy international audience. the world is so crazy right now, can you ever see a time where she might want the government herself? hello translation: i never thought of it, but that is interesting. in a world of growing distrust in politicians

and increasingly pervasive celebrity culture, that idea might be more pressing than is comfortable. and on that cheerful note... bye—bye. hello and welcome to the week in tech. it was the week we celebrated 30 years of the world wide web, while social interactions took a hit as facebook, instagram and what's up face outages across the world. and the national crime agency revealed a new cartoon targeted at four to seven —year—olds to teach them about staying safe online. it was also the week we got a genderless voice assistance, a tea m a genderless voice assistance, a team of linguists, technologists and sound designers created it. it is aimed to help fight gender bias in smart assistance. more details were revealed

about harry potter wizards unite. the augmented reality game was created by the pokemon cocreator. players will be searching for items, playing spells, and battling death eaters. a japanese company has announced plans to work with toyota to develop a human operated space robot to be launched in 2029, and finally, meet metafly. it is an insect inspired drone that has created quite a buzz. it can reach speeds of up to 11 miles an hourand it can reach speeds of up to 11 miles an hour and five after eight minutes on one charge. lightweight and highly manoeuvrable, it can even be flown indoors. —— fly for. when it comes to building a country,

you would be hard—pressed to find a more unpredictable bit of land injapan. perched atop four tectonic plates, japan's islands in the heart of the volcanic zone of the pacific ring of fire. there are over 100 active volcanoes in japan, fire. there are over 100 active volcanoes injapan, and each year, about 10% of the world's earthquake energy is focused around the country. understanding nature in japan can mean saving lives, but how do you predict the unpredictable? iamon iam on my i am on my way to shimmer, about eight hours by night boat out of tokyo. oshima is the start of a chain of islands with a violent history, history born in fire. —— natsu. i am history, history born in fire. —— natsu. iam here history, history born in fire. —— natsu. i am here to meet a doctor and his team. between them, they have spent decades studying the active volcano at the

heart of the island. oshima was near the epicentre of the infamous great earthquake in 1923 that killed an estimated 140,000 people. since then, the volcano has fallen into a cycle of erupting every 30 years or so. cycle of erupting every 30 years or so. that means another one is due any time now. on the day of the eruption, hundreds of crows were perched on the stone pagoda, which was peculiar. i went to the crater late in the afternoon. there was a seismometer placed just above where we are heading to right now. we're on our way now to the summit of the volcano to check an instrument that the researchers have here, you can see in the background behind me, some of the smoke coming out of the ground from the active volcano. and we are surrounded everywhere by this black, leftover lover, some from the 1986 eruption. that eruption started over here and down

this hill, towards the town of 10,000 inhabitants. fortunately, did not quite make it but they did have to evacuate. a team of visiting the mountain to check and repair the centre stations dotted around the mountain. it is a small magnet to if you heat up a magnet, magnetisation vanishes. then we can detect a change. before the eruption of the volcano. the team's measurement stations can only attract a relatively small area. to mount more of the mountain they need more perspective. this unmanned helicopter can cover a much wider area and have a much more data. it is not something they can do everyday. over one third of people injapan everyday. over one third of people in japan live within everyday. over one third of people injapan live within a hundred kilometres of an active volcano. so having an early warning is

invaluable. but knowing what to do with an eruption does occur is just as important. back on the mainland, researchers are using computer simulations to predict where ash could fall in the event of a major eruption. they are using historic records and examples from the last eruption of mount fuji over 300 yea rs eruption of mount fuji over 300 years ago. the day of the eruption the blue skies were filled with volcanic ash. the close you've got to the volcano, the cigarette was that it over one metre of ash fall according to historical documents. it was the edo period so people were living simple lives. imagine is something of this scale happened in this day and age full of electronic technology. who knows what kind of damage it could lead to. it is a com plete damage it could lead to. it is a complete unknown to us. over in central tokyo the team ‘s data is ready starting to have a practical impact outside of the laboratory. this is where all that data

ends up. this is where all that data ends up. this is where all that data ends up. this is the volcano an earthquake monitoring room of the japanese meteorological agency. these guys are here a round the clock ready to raise the alarm should anything be expected. they are tasked with raising the alarm in event of earthquakes, tsunamis and volcanic eruption. and now new research is bringing that rapid response to other types of extreme weather as well. japan's geography means flash floods can happen in minutes. 20,000 rivers are recorded and assist in this country and i think this is unheard of in any other country. in japan, landslides and flooding have taken many lies. even in recent yea rs. taken many lies. even in recent years. advancements in radar sensor a ccu ra cy years. advancements in radar sensor accuracy and map data means the system accuracy and map data means the syste m ca n accuracy and map data means the system can raise the alert about dangerous flooding in near real time. every ten minutes if it's needed. slowly but surely

researchers across japan are understanding how these seemingly untameable natural events work each time they do it makes the people of japana time they do it makes the people of japan a little safer. one of the memories that will always stay with memories that will always stay with me is our visit to the fukushima day cheap nuclear power plant that was devastated by the 2011 tsunami. exploring the wrecked reactor site showed how difficult it is to build robot to navigate wreckage and rubble. today i have come to a university to meet a machine that was inspired the mihara disaster. it isa was inspired the mihara disaster. it is a big beast weighing over 150 kilograms. each limb stretches to more than one metre in length. the need to move across uneven terrain has caused a bodice is to investigate many kinds of designs. and although robots with wheels or with snakelike bodies can handle

tricky terrain, they are not so good when you need to get hands—on. tricky terrain, they are not so good when you need to get hands-on. after we reached the destination the robot has two perform, it has tasks like turning a valve or manipulation of switches or opening doors, things like that. it requires big power.m order to actually manipulate things, it would need additional hands or fingers of some kind. for now, the tea m fingers of some kind. for now, the team are investigating the best way to move. calling it low and slow over the rubble. i notice that it is not just using its over the rubble. i notice that it is notjust using its forelegs it is also using it belly. yes. so all the legs can come off the ground at once. i don't thinki have legs can come off the ground at once. i don't think i have seen that before. yes. this is a new locomotion style proposed by. is quite difficult, even free human to along this place. but if a

robot ruse in a crawling motion it will be sta ble ruse in a crawling motion it will be stable because its belly is almost on the ground. so it has a very low centre of mass. spikes on the belly help to stop it slipping on the rubble and also help it rip on two corners as it was itself up and down. and although it is not strictly a self balancing robots it does not really matter if it takes a tumble because it is symmetrical. so we can still work, back to front and upsidedown. as you can see when it is not in its weird spiderform it is not in its weird spiderform it is actually quite human shaped and human sized. there is a good—sized that —— reason for that because it is expected to work in an environment where a human would work so it needs to sit in the same places and not we any more than a human so does not disappear flew the floor. japan is one

of the few places where robots are leaving the laboratory and entering society more widely. were other societies may have reservations, had japan desperately want this to happen. in the run—up to the 2020 olympics, japan is looking for more ways than ever to have robots do the hard work. the self driving electric wheelchairs made by panasonic have already been rolled out for testing already been rolled out for testing a tokyo's international airport. but what is new is my luggage buddy here. newcomb popular suitcases in there and it will follow the wheelchair wherever it goes, slowing down and speeding up as necessary when it goes up and down sloping surfaces. perfect for an airport. when it goes up and down sloping surfaces. perfect foran airport. if a roaming traveller walks in front of the chair. along with the luggage katie. although a crowded airport i can see wandering people getting in between the luggage and the chair which might lead to

some frustration. panasonic hopes to have the chairs available in airports and public spaces across japan in time for 2020. in the past, japan and has not had the greatest record for accessibility. 40 million visitors expected to come to the olympics and paralympics, organisers have pledged to use this as an opportunity to fix these problems and make tokyo a more inclusive and accessible city. disabled passengers in need of assistance will be able to summon a wheelchair through an app. it will then take them where they need to be without stress or hassle. something am sure able—bodied travellers could appreciate after a long journey as well. for many visitors coming to the olympics next year, the japanese language will be challenging to say the least. we found

a translation tool that looks like it is straight out ofa that looks like it is straight out of a competition. perhaps the olympics and paralympics greatest achievement is her ability to bring people from all over the world together. as well as being positive will so bring challenges, notably around language. one japanese graduate students supported by an accelerator along is side panasonic has created a special project to try and get the world talking. city dash is the japanese word for speech bubble. it is a screen on each side link by bluetooth. words spoken by one person will be translated on the opposite scheme —— screen. one person will be translated on the opposite scheme -- screen. people use a phone to communicate with foreigners that nobody likes it because a phone is more like a way to ask a concrete issue like where is the station. the technology

behind it is not necessarily anything new. it uses the full api to facilitate the flesh with the application of the technology is interesting. it is hoped the system can be rolled out across the games that it and beyond, the creator hopes to take the system much further. the next stage, maybe people can have small devices to use anywhere any time. at present, the system anywhere any time. at present, the syste m ca n anywhere any time. at present, the system can work between four languages are japanese, english, chinese and korean although there are plans to extend the range much further. the prototype also requires access to data signal. further. the prototype also requires access to data signallj further. the prototype also requires access to data signal. i almost want to ta ke access to data signal. i almost want to take with me for the rest of my time injapan. to take with me for the rest of my time in japan. can i keep it? and thatisit time in japan. can i keep it? and that is it for our olympic special from the tokyo olympic stadium which

next year, of course, will be at the heart of the action. don't forget that we live on facebook and twitter. thank you very much for watching and we will see you soon. we have some rough weather to start today. heavy rain, and hill snow and strong wind on the weather menu for us today. the culprit is this area of low pressure that continues to develop as it works in towards the united kingdom. we already have rain extensively falling in northern ireland so if you're heading outside here in the next few hours it will be soggy and the rain could bring localised surface water flooding here.

there are big contrasts in temperature. generally england and wales are staying mild but further north it does get colder and colder with eight patch of frost or two in scotland. as we go into saturday this area of low pressure continues to develop and will interact with some of the cold air, hence the risk of some hill snow across northern portions of the uk. in the south there is no risk of that because we have much milder air pushing in. so saturday, rain first of all. that wet weather moves away from northern ireland and showers followed. the rain will be heavy across the hills of northern england and the hills of wales where we could see 40, 70 millimetres, possibly 100 over the highest ground in wales and that brings the risk of localised flooding. as well as the rain we have the risk of some strong wind gusting at around up to 60 mph around exposed coastal locations and heavy snow further north. there may be snow across the high ground of northern england and northern ireland but not lasting long. it will last longest across northern scotland,

north of the central belt where there could be something like ten centimetres of snow building up around above 200—300 metres of elevation. a mix of weather on saturday, heavy rain, hill snow or strong wind and there is the potential for transport disruption. that continues through saturday night as a squally band of rain pushes eastwards across england followed by plenty of showers. those showers still have a wintry flavour in them across the hills of the north and west of the uk and it will be a chilly and blustery night. our area of low pressure responsible for this lot will continue to deepen as it moves away from the uk and that continues to feed in some strong wind across northern areas of scotland. north—westerly wind breaking in plenty of showers of the second half of the weekend. and although it is true that the majority are showers across the north—west, still was a wintry flavour, nowhere will be immune from getting a downpour. some of those showers will move to eastern parts of the uk.

temperatures on the face of it around nine or 10 celsius, feeling cooler in a north—westerly wind. next week becomes quieter, dry around warmer.
