this is bbc news, the headlines: a federal emergency has been declared in the us state of kentucky after floods caused at least 25 deaths. the governor, andy beshear says many residents remained unaccounted for, while hundreds of homes and businesses have been washed away, in the east of the region. the white house says president biden has tested positive for covid—19 for a second time in two weeks. doctors said the 79—year—old returned the test, after four consecutive days of negative results. he is now back in strict isolation at the white house. pope francis has said health problems are likely to force him to scale down his busy international travel schedule, and may even lead to his retirement.

speaking after a six—day visit to canada, the 85—year—old pontiff said his age and frailty had led to his decision. now on bbc news, click. the next train to arrive on platform one is the stopping service. �* , ., platform one is the stopping service. �* , ., service. and you can stop doing that silly voice, _ service. and you can stop doing that silly voice, by the - service. and you can stop doing that silly voice, by the way. - that silly voice, by the way. we are on an augmented reality walking tour then we are off to an oil rig where pets are

charges you. one system using bluetooth beacons is already active in genoa, and paul carter has been to take a look. our cities are changing. and so, the way we navigate them is changing too. in many major cities around the world, technology being used for integrated fares and ticketing across modes of transport are now commonplace. but making such multimodal systems truly frictionless by removing the need to buy tickets is taking things to the next level. and in the northern italian city of genoa, they're doing just that — in some

instances, quite literally. in partnership with hitachi rail, the city is piloting a new system to allow seamless, hands—free payment and ticketing, all from a smartphone. the system works across the city's varied networks, including buses, subways, public lifts, water buses and funiculars. it's a really unique city when it comes to the geography. we have the sea, then we have mountains. we have up and down hills, we have elevators, whatever, so we have inside of the offer of the main operator, at least seven or eight means of transportation — that's really something unique. normally, you have either bus, tram or underground — that's it. you have literally everything from boats to elevators. so we thought that if we managed to connect this city, which is really, really, really complex geography and landscape, i mean,

we can scale up as much as we want. it uses bluetooth beacons placed throughout the city, which automatically detect the journey a passenger makes and what modes of transport they use. it's pretty easy. i mean, we covered all stops of buses, underground, elevators, funiculars, track rails of the city. we equip them with bluetooth sensors and each and every mobile telephone nowadays is fitted with a bluetooth antenna, and this communicates throughout the app to the sensor and localises the position of the travellers in association with a particular stop or a means of transportation. i mean, what you have to do is literally know where you want to go and then board and deboard the means of transportation you want, change intermodally between, i don't know, underground and buses and funiculars. and then the system will calculate the travel chain. and at the end of the day, it calculates the best possible fare for the segment

you travelled on. in addition to public transport, the app is also integrated with genoa's car—sharing service. e—scooters and parking can be booked and paid for through the app. as well as benefits for passengers, systems like this also have benefits for the transport providers. the data collected can be used to calculate congestion and even emissions, allowing companies to dynamically adapt their services. passengers also have access to arrival times and even how crowded a bus or subway train might be. the man responsible for public transport in genoa thinks this isjust the beginning. our vision is changing. we only want to be on the leading edge of technology, trying to understand what will be happening not next year, by the next three years, because you need time to get ready to new technologies. i think that the future,

the public will ask for a lot of transformation. technology will be much more important. on—demand service will be increasing in importance. so i think the future with public transport, also, new technology like electric, like driverless cars, so i think the future of transport will be a future for big technology change. the 360 pass app and smart mobility system deployed in genoa is currently in trial, but discussions are taking place with other cities around the world to expand its use further. perhaps one day, hop on, hop off really will be the transport of the future. that was paul. it can be fun to hop on a train, and seeing as we normally have our smart phones on us, we can have a map to hand and maybe even a torah but one project is hoping to up

the game. story trails is using augmented reality and virtual reality to see a little bit more of a city you visit. lara goodwin _ more of a city you visit. lara goodwin has _ more of a city you visit. lara goodwin has been _ more of a city you visit. lara goodwin has been to - more of a city you visit. l:—. goodwin has been to dundee more of a city you visit. l55 goodwin has been to dundee to check it out. goodwin has been to dundee to check it out-— check it out. this is the tale of two sides _ check it out. this is the tale of two sides to _ check it out. this is the tale of two sides to a _ check it out. this is the tale of two sides to a city. - check it out. this is the tale of two sides to a city. the i of two sides to a city. the virtual on the trodden and the head and. and now and immersed of project called storytrails allows people to see both of these for the first time. to see beyond a city's geography and instead gaze into a 3d map of its very sole.— of its very sole. this is an exciting _ of its very sole. this is an exciting moment - of its very sole. this is an exciting moment in - of its very sole. this is an l exciting moment in history where we have a new form of 3d filmmaking. we were so excited to see what sort of stories could we tell if we gave it to diverse creatives from the town and communities who told stories that were important to them that made that public space a new, digital kind of public space.— space a new, digital kind of public space. space a new, digital kind of --ublicsace. , ., , ., public space. the story map for dundee focused _

tech is now available on some smartphones. there has been such a huge advance in what is literally in your pockets at the moment. so using a high—end smartphone, you now have access to two key technologies. one is lidar and one is photogrammetry, both systems which are used to capture 3—dimensional space. lidar uses a laser to measure the distance between your camera and object and from that works out the 3—dimensional form. photogrammetry is actually a technology which is over 100 years old. and it uses hundreds of photographic stills and compares them to also work out the 3—dimensional form. previously, technology like lidar couldn't be accessed byjust anyone. a traditional lidar hand—held scanner in construction, for example, cost more than £20,000. it's once technology gets into the hands of the man and woman on the street, once they literally do end up on your pockets, that makes their accessibility and their creative potential much more real.

what's nice about this is that although each location is recognisable, you put a little creative play or twist on each one. we wanted to reflect the city broadly. but we wanted the people whose stories we present to, in effect, shape what the city looks like. it's one of those worlds that is somebody�*s biography. it's not a literal map, we aren't building a literal model of dundee, we are building a model almost based on people's public memories. it's notjust dundee being emotionally mapped into animated film and standalone 3—d scenes. the free story trails exhibit moves and focuses on a new uk location every week ending with lewisham and london in mid—september. you can capture a huge amount of detail, can't you. yeah. this is andrew, one of our designers. a full—length scan like that may take us less than a minute. we could maybe give you a try. 0k.

try to be as still as possible. it helps if you focus something like in the background. and here we go. look at the detail! we can even see the individual strands of hair. i think if you're working in a world where you are constantly doing digital avatars and representations of people, you can lose that connection. we spend a lot of our time trying to actually remove the digital and reintroduce the human. so there is 3—d mini me, all created using an app and ipad. what's really interesting about this project is how this technology is being used to capture a city's soul to tell its residents' untold stories, and

that's a very interesting merging of humanity and the metaverse. time for a look at this week's tech news. first up, kim kardashian and kyliejenner are the latest celebs to join content creators in their criticism of instagram's new design. instagram boss adam mosseri admitted there had been a lot of changes to the app. the tempest jet demonstrator has been unveiled a few years ahead of its 2027 release. it'll use artificial intelligence to assist the pilot if they feel overwhelmed or extreme stress. procuring off—the—shelf gaming kit and trying ideas out quickly and cheaply. the idea is fail fast, let's get stuff in, let's see if it works, what benefits it could give to the operator. sticking with aviation, airbus and vrm switzerland are developing a new,

innovative virtual reality helicopter simulator. the training tool offers realistic flight behaviour and full—body immersion with high—resolution scenery. it is an advanced take on the two companies' previous collaboration on vr helicopter training. after soaring global temperatures, cities in the us are rolling out new measures to turn down the heat. cool pavements in locations, including la and phoenix, are coated to absorb and radiate heat, as temperatures there have caused blackout spells to reach up to 67 degrees celsius. —— black —— black asphalt. there are lots of incredibly dangerous workplaces and a drilling rig is probably one of them. we've just had a talk with the safety manager who has pointed out everything on board that could potentially explode,

and the only way to get people in when you are hundreds of miles away at sea is via a helicopter to do an inspection. so using robotics to monitor the space and keep an eye on things could be a solution. this particular rig in norway has been parked up for refurbishment so the robots can be put through their paces and get some practice in. this robot, known as weik, is making a 3—d map of the whole rig, a bit like a google street view. why is it called weik? weik — weik is a norwegian word which means to wake and watch. wake and watch, ok, so it's like a waking watch. when no—one's on the rig, weik is going around? exactly. it is not producing live footage of the rig, so what would someone want a street view of this kind of environment for? it can be used on shore, so if you plan to do

maintenance. it can take images every hour, for instance. there's a lot of information to gather. of course, for a human, it is easy to make mistakes. the robot can handle it much more easily. all this data allows the company running at the robots, cognite, to build a digital twin, a full, virtual 3—d model of the rig. that map allows the robots to run autonomously, and the images taken can be compared over time to see if something has changed and might need repair. it's very different to how things currently work. at the moment, i think it is every two years that we do a complete ex inspection of all the explosion—proof electrical boxes on the drill floor or various parts of the rig. if you had a robot on board, you could be doing heat tracing each month. you could be doing ex inspection whenever you choose, in fact. and doing a full inspection means looking very closely in some very hard—to—reach places. as you can see on this rig back here, we have a very

high drilling tower. you typically need to inspect that pretty often to look for loose bolts and things like that. the drone can do that with a remote control. it is very easy to do that. we can automate them by using our software. we also get the images in precisely the same location as the last time so it is very easy to see things happening over time. mapping is one thing but the robots also provide important safety functions. in the case of an explosion in a given area, we may not want to put personnel in that area, so we could send in the robot in that case to take readings. and down into the depths of the rig, the star of the show is being put through its paces as a safety inspector. what spot is doing is doing a mission autonomously,

which means that it is navigating an inspection round and gathering the data we are basically most interested in. and this is one of the rooms that allen said could be explosive. how confident are you that spot is not going to bump into anything? we are quite confident about that because it has a really good track record. also, it also has sensors mounted to it so that it can sniff any potential explosive gas the area, and whenever it detects some gas, it will immediately shut off its motors. and spot has stopped here at this control panel. what is going on here? what we can see here is lots of valves and a lot of gauges. what spot is doing is taking images of this instrument panel so that we can digitise this highly kind of analogue instrument. we are comparing it, making sure that everything we see out here corresponds with what we have in the control system. so, if one of these levers is in the wrong position, spot will know? yes. aren't there already digital

sensors in a place like this? surely you can get digital readings from... yeah. not necessarily from everything. there is lots of analogue instruments, such as this instrumentation panel right here. why would you notjust install cctv in every room and have a fixed camera on this rig? so, typically, we are seeing that fixing all cctv cameras, fixing lots of sensors, it's actually really, really expensive, and if you were to mount hundreds of different high—quality sensors all around the facility that would be a waste when you can mount one piece of sensors on a mobile robot that can gather all the data you are interested in. i guess this is also a lot more fun. yeah, definitely is. until i visited this rig, i did not really appreciate how dangerous a workplace like this really could be, and while oil rigs could

be coming to the end of their lives, using robots could help reduce the cost of working on industrial sites like this in the meantime, although it does make the place a little lonelier for the handful of humans left behind. that was chris. now, while facebook�*s owner meta has pinned its hopes on virtual reality, some other tech giants think augmented—reality glasses are set to change the way we interact with the world and each other. but they may not be ready just yet. i am about to test snapchat�*s latest spectacles. this is the fourth generation and currently it is only a developers kit, but there is one big difference. it is all about augmented reality. i scroll through the options with my finger here. solar system. let's give that one a go. i think i need to stand up for this.

i am in the midst of the solar system. i could see the images overlaid on my surroundings, but we weren't able to capture that, so these images are of someone from snapchat testing it outdoors. there is lots of stars. i am in space. chunky as they look, they did feel light enough to wear, but they were a bit tight, even on me. this time, i am going for magic forest. this app demonstrates how you can place things on any surface. there are some flowers growing out of chairs and butterflies are flying all around serheil, who's filming. if i hold my hand out, the camera should recognise it's there and a butterfly might land on my hand. come here! i am trying to reach for the butterfly, which is doing nothing. that is the first law of click. it all goes wrong. much like the other snapchat spectacles, you can capture a picture. there is also a button here that provides the scan

function which is the same as you get within the snapchat app, so you look at something and it can bring up relevant information or provide the lens that you might be after. but before i remove them, time for a spot of art. i am moving towards the sculpture and it seems to be telling me to do this with my hand. oh, wow. 0k. something is happening. 0h, bits are growing out of it. flowers are growing. what happens next? on this prototype, the field of view is actually quite limited. there is just a section there that gives me the augmented reality and then i just see the room through there, all through there. but i like being able to use the hand gestures, and it is recognising my hands quite easily. this is about a lot more than just playing or art though. i think ar glasses have a huge role to play in the future, and these are hardware devices that we are asking people to wear on their faces, so they really need to provide

value to the user almost every minute they are wearing them. i think a good example is you can imagine you are walking down the street and your friend has recommended you a sushi restaurant. with a mobile phone, you would have to pull your phone out, look at your friend's messages to be able to find that a sushi restaurant. if you are wearing ar glasses, we would love to provide you the most relevant information right then and there. if you are trying to catch a bus and you are walking past the bus stop, these glasses can provide you really useful information about the bus timetable, if there are delays, just by walking past the bus stop. this will be made possible via approved third—party apps, both within snapchat as well as snap camera kit features within theirs, but a consumer version will need some improvements. they certainly felt intuitive to use, even though i did have to wear three different pairs for them to survive our filming as they kept getting overheated, but do i think that

if we can overlay real—world things like maps and steps, the kind of data you want, they could be quite useful once the battery life is sorted. the thing is, right now, i have just looked at some games and stuff that is a little bit immersive, which was fun, but would i want to do it again? i don't know. i think they need a real—world purpose. so, you found the field of view disappointing? yes, there is a real trade—off between battery life, the weight of the glasses, and how much augmented reality you are going to get in them. but hopefully by the time they are a consumer device that will have balanced out a bit better. let's hope so. we have been talking about that for ages, haven't we? anyway, that is it from us from the riverside transport museum. thanks for watching, and which one do you fancy driving home? i will have the bus, please. bye for now.

hello there. saturday was a warm and humid day for many of us. in places, we got to see some sunshine. in other places, the humidity gave rise to a lot of cloud, mist and murk and some outbreaks of rain, and there's more cloud and rain in the forecast for sunday across some parts of the uk. the sunniest conditions will be up to the north. the earlier satellite picture shows this pipeline of cloud, bringing some outbreaks of rain. we're starting sunday on a pretty soggy note across parts of wales, northern england, the north midlands, eastern england too. very little rain getting down into the south, but quite a cloudy, murky start to the day here. much of the rain will tend to peter out. still a few showers into the afternoon, but a bit more in the way of brightness developing, particularly in north wales and northern england. all the while, northern ireland and scotland will have the lion's share of the sunshine. always a bit more cloud

for eastern scotland. cool and fresh here — 16 for aberdeen, 18 degrees from belfast. still quite warm down towards the south and the south—east. it's triathlon and pa ra—triathlon day at the commonwealth games. quite a lot of cloud, some spots of drizzle to start. should brighten up later on. and for the women's euro 2022 final at wembley, chance for a shower. i think, on balance, it should be dry, quite warm and muggy for the kick—off. so, yes, we could just see the odd shower drifting across the south—east corner during sunday evening, but overnight, into the early parts of monday, we'll see largely clear skies overhead, light winds and, actually, particularly up toward the north, something quite cool and fresh. seven to start monday in glasgow. still 17 there in london, so still a bit of warmth clinging on in the south. monday getting off to a fine start in most places, with some spells of sunshine, but we see another area of cloud starting to push in from the west. that'll bring rain into northern ireland through the afternoon, perhaps fringing into parts of west wales and the far

south—west of england. ahead of that, actually, another relatively warm day. 21 degrees for newcastle, 26 once again in london. as we move out of monday into tuesday, we see this area of low pressure bringing frontal systems and outbreaks of rain, but not much of that rain getting down into the south, where we really do need some. in fact, southern areas through tuesday are likely to be very warm indeed — 27, maybe 28 degrees — with the rain further north and west. it is then set to turn cooler but drier for the end of the week.
