big hotels and big entertainment. and everyjanuary, it's also home to big tech because this is where ces happens, the consumer electronics show. now, it takes place across the city in hotels like this and also in the massive las vegas convention center. this is where we get a taste of the tech trends to come for the new year. and over the years, we have seen it all here — autonomous cars going up and down the strip, even a flying one on the sidewalk. so what's going to be big this year? it is time to find out. the self—proclaimed most powerful tech show on earth truly is global, with companies from around the world battling for attention and some splashing out to make a real spectacle. there's even a mini theme park in one of the halls this year, with a hydrogen—powered train that goes... ..all of a few metres. so lovely of them to name it after me too! i think that's a different sk. 0h, 0k. but after a year of tech hitting the headlines, often for the wrong reasons, there's no existential crisis here. the buzz is back... dance music plays ..the party's pumping, and ces is a scramble of people, products and predictions for our future lives. everything you could ever think up appears to fill these seemingly endless aisles where incredible innovation collides with absurd apparatus, allowing you to take the mic... he mimes t0 rock music ..go for a ride or shoot some hoops. oh, well done! honestly, i don't know what all the fuss is about. it's easy. talking of hoops — even next year's drone soccer championship has a stand. although it's more like quidditch, if you ask me. there was a time when ces would feature a deluge of tvs, each one bigger, brighter, sharper, smoother and thinner than the next. they are still here, including the occasional whopper, but tv picture quality is improving much more incrementally these days, and the real screen innovations are happening elsewhere. got to hand it to lg, the company always puts on a display, and this year that display is transparent. these oled screens look astonishing. although, come to think of it, you probably wouldn't really want to see through your tv screen at home. you'd want the blacks to be black, wouldn't you? so i feel this is probably more for use in eye—catching advertising displays. oh, and even though it says wireless, that's not quite true. you still need a power cable, which does beg the question, why not run the hdmi cable into it at the same time? transparency does seem to be a thing this year. here's a strange roll—out display that you can see right through too. now, the video actually comes from a normal projector, but whereas that projection would go right through normal glass or plastic, this so—called nano optic material catches more of the image. it really does look quite bright in real life. so, in theory, with this material, any window could become a display. this is a mesh of led pixels, but between the pixels, instead of there just being black fabric or even glass, there's holes, so you get this transparent display effect that's much easier to manufacture, especially at size, than normal led or lcd panels. here's something that first caught my eye a couple of years ago. the looking glass display is the best glasses—less 3d display i've come across, and it's now available in a big and a small version. as you move your head, its lenticular screen really does allow you to see the images from different perspectives. unlike traditional 3d tvs, here the background really does emerge from behind the foreground as you move from side to side. now, wherever your tv is in your home, i bet it's been there for a while, hasn't it? yeah, well, displace wants to change that. they want you to be able to take your screen anywhere. now, in order to achieve that, this screen needs to do two things. firstly, it needs to have no wires, and secondly, it has to stick to your wall. so let's break that down. number one, no wires means no power cords, so this thing runs on batteries. and to make sure that you're not charging it all the time using a wire, four of those batteries are hot—swappable. pop them out, charge them elsewhere, pop them back in again. number two, it sticks to the wall using suction cups that are also powered by batteries. now, i admit it does seem a bit weird that you want to just pop your telly off one wall and pop it onto another, but if you do, well, at least it only weighs iikg, so you don't need to be quite as pumped as our man here to lug it about. now, i know what you're thinking. what if the batteries run out? does this thing fall off your wall? well, yes, but slowly. because they've given it a kind of...airbag system. yes. if it detects a suction failure, it fires adhesive strips at the wall and slowly lowers the tv to the ground on wires. less air bag, more bungee, i suppose. so that's ok, but i can't help thinking they've had to invent a whole new safety system as a precaution for their whole new attachment system. overengineered much? given everything that's happened in the world of ai over the past year or so, it's little surprise that here plenty of companies are keen to talk about what they're doing with it in their products, and that's particularly true when it comes to health care. well, one of the first things that many of us do in the morning is look in a mirror. so if you're not wearing numerous health trackers, like i do, how about the idea of that mirror being able to tell you how your health is doing? lindsay, let's have a go. tell me about the technology, first of all. absolutely. so this is our newest product, it's our anura magicmirror, and what it does, it does a 30—second video selfie and we actually measure over 30 vital signs and risk of disease parameters. so everything from heart rate, breathing, blood pressure to actual risk of cardiovascular disease, risk of stroke, risk of fatty liver disease — many different parameters, so... how on earth do you assess all of that from looking at someone with a camera? yes. so how it works is we're actually measuring the facial blood flow patterns underneath your skin using reflective light patterns. so we use a process called transdermal optical imaging. and so what happens is we take a 30—second scan, we analyse your facial blood flow patterns, and then it gets sent up to the cloud for processing. and so we output all these calculations. 0k, brilliant. yeah. shall we try it? well, let's have a go. let's try it. sit still. and it's... it's already begun the scan, so we'll have your results quite shortly. make sure you're in the right spot and it'll be done in 30 seconds. i'm doing well on most of these things, which is great. my risk of heart disease, stroke — all incredibly low. but some of these things, it's hard to imagine how they would even be calculated. when it comes to something like type 2 diabetes risk, how on earth can it assess that? so in the background, we have a population of about 40,000 patients where what we've done is we've taken their demographic info, all their medical history. so this number you see here is the percentage of users with your facial blood flow patterns who are at risk of developing type 2 diabetes. great — if it's not going to get you in a panic when things aren't right. and there was one little niggle in my brief experiment. whilst the differences are pretty negligible, i've redone the scan a couple of minutes after doing it the first time, and the figures are just slightly different. it tells me i'm 36. apparently i was 38 a couple of minutes ago. same face, but i'm happy. can i go with this one? meanwhile, plenty of wearables being launched here, and many of them are pretty compact too. in fact, there's a whole trend for smart rings, with a few new ones launching. the 0ura has been popular for a while but this is ultrahuman. this goes beyond tracking your daily activities and giving you a readiness score, though. it actually acts as one big data platform, bringing in information from blood tests and also, if you wish, from a continuous glucose monitor. so, for example, you could see how the sugar that you've eaten has affected your night's sleep by having all of that in one place. much hype about it in tech circles as the company has high hopes. initially, the blood function will be india—only before expanding, and an air quality monitor to also sync the conditions you sleep in is coming. here's a bit of a different way of being able to assess your heart rate and how stressed you may be. these are mindmics. now, they work as regular earbuds — you can listen to music, talk on them. but they also are listening within your ear, like your ear becomes a speaker to your heart. it's very buzzy here, but i'm feeling quite zen. in just a couple of minutes it's told me my heart rate was 57, my heart rate variability was 51 and apparently i am well in the rest and digest category, not fight orflight. these devices do also seem to incorporate our mental health too — in particular stress. and i'll have more health—related gadgets next week. in recent years, the automotive industry has become a bigger part of ces, and this year was no exception. from concept crab cars to electric diggers, via bikes lifted straight out of tron, vehicles and now big news in vegas. but it's notjust the cars themselves vying for attention. a major theme coming from many of the companies focused on what the marketing speak labels as the "in—car experience". it's essentially using tech to make you, the driver, the star of the show. so, naturally, one car company brought in a star of their own to demonstrate their latest big idea. imagine a car that's creatively bold. now, imagine a song conducted by the road... mercedes has teamed up with musician and technologist will. i.am to create sound drive. ..and your foot on the pedal means it's time to jam. it takes telemetry and information from a range of sensors, including acceleration, steering and gps, to dynamically change specially produced tracks in real time. # it's the bass line running, running... how do you simulate gravity pushing down on the engine where you have those subtle oscillations? there's some subtleties that happen when you go, "mm...." you feel that, you hear that. you pay attention. and because i'm an audio nerd, i pointed that out and i told them, "hey, i think i could solve that. "if you give me sensors, i could point those sensors "to an audio generation engine and i could oscillate gravity "pushing down on an engine — i could simulate that." and then i said, "hey, but i think the future "of electric vehicles is more than vroom, vroom. "if you let me just, like, go free—fly, "i think i could come up with something truly "transformational. " and so they were like, "yeah, try it out." i'm like, "are you serious?" naturally, i wanted to give it a go to sample that "in—car experience" for myself. this is wild! it's undoubtedly impressive from a tech and music perspective. music plays. wow. you can really feel that rise up with the acceleration. so what this system is doing is it's collecting information from all of the sensors in the car, so that's accelerating, braking and steering, and it's using that information to dynamically adapt the music that's playing. it's pretty cool. but it'll be user and industry take—up that determines whether it goes beyond a very fun gimmick. elsewhere at the show, autonomous driving and all of the connected industries continue to be a big draw. luminar create lidar products and software for self—driving cars. this year they were showing off the latest update to their hazard—detection capabilities. the system is designed to react faster than a human can, in this case swerving to avoid a dummy of a small child at a split second's notice. let's buckle up again, then. rock music. are you belted up? yes. 0k, we are ready to proceed. three, two, one. go. whoa! it's effective... ..if not a touch disconcerting. wow. the company says it won't swerve if doing so would take the car into obstacles or other danger. ces shows that the line between the car and technology industries has blurred to a point where one now barely exists. like much to be seen here, though, how much actually makes it out of las vegas remains to be seen. the franchise dries heavily on radiant culture. it the franchise dries heavily on radiant culture.— radiant culture. it was super important — radiant culture. it was super important for _ radiant culture. it was super important for us. _ radiant culture. it was super important for us. scientists | radiant culture. it was super- important for us. scientists from california have _ important for us. scientists from california have successfully - california have successfully completed their first solar powered project in space. the space solo demonstrator was able to be in power wirelessly. the test will help chart the future of space—based energy and how one day it might be transferred to earth. finally, artificial intelligence is expected to affect nearly 40% of all jobs, intelligence is expected to affect nearly 40% of alljobs, according to new research by the international monetary fund. the suggestion is higher income in year younger workers may increase, but lower income in all the work could fall behind. we're back at the massive consumer electronics show in las vegas, which is notjust about the big companies with their big flashy stands. alasdair keane has been to what i think is the most exciting hall of all, which mayjust contain the next big thing. this is eureka park, a space packed full of start—ups all trying to find new customers and investments. but what does it take to present your tech on the global stage? let's go meet some of them. my name is mirko cesena, a co—founder ofjedsy. i'm from italy originally but four years ago i moved to switzerland for founding this company together with my partner, herbert weirather. i'm peter yau from hong kong and our i company is called xox0 beverages. i hi, i'm beatriz. we're from st37, so sport and technology for 37 olympic sports. this really is an around—the—world trip in bright ideas, with many of these start—ups bringing their tech to this huge event for the first time. that makes it an ideal hunting ground for those looking to invest in the next big thing. the entrepreneur is so important and so special in being able to make an opportunity successful. they've got to be able to walk through ten—feet concrete walls in order to make their vision a reality. passion must play a role in it as well, if the company is passionate about it? to be an entrepreneur you have to be a little bit crazy. you have to believe that what you want to bring to the world that doesn't exist needs to be there, and most other people don't see that. what we do is we have created - a machine that is focusing on making cocktails and mocktails. so now the machine itself is... we're doing a rental business to all the businesses - like bars and restaurants, so they can help to - produce different drinks. it's a drone that goes onto the side of buildings? exactly. we take off from the building and we land in the other building, so basically flying in between these two places makes us very efficient because doctors and nurses, theyjust need to open the window and place the package inside the drone, or also take it out as soon as it arrives, and it charges automatically. it does everything by itself. we need no manpower at all. so we do ai video analysis, and today we're presentingj it, the application, _ into video refereeing specifically. so you have trained computers on the rules of sports... exactly. ..and it can replace the referee? it could. it could, actually. for now we give the assistance for the referee so he can - have the final call. this is a new cooking technology to cook and bake your food. it is a way to cook fast at low temperatures. and we do that with running electrical currents through your ingredients. we have developed specially for ces a blueberry muffin square, where the cake base has been baked from a raw dough to the cake in three minutes and in addition that cuts also 90% in energy use versus a regular domestic oven. this certainly is a place where you'll see new ideas being brought to the world. so can these inventions make it to the next stage and the mass market? the proof will be in the pudding. jaunty ragtime music. i don't know about you, but i still love a robot. here's one that's making me a latte. i tell you, this had better be a blooming good coffee! whether or not it'll beat the human barista, or indeed the coffee maker, depends on your point of view, i suppose. but this type of bot certainly generates a bit of interest at these shows. ho, ho, ho, ho! "bbc foamy hazelnut latte" — they even know my nickname! robot: thanks for coming. have a nice day. i will. thank you very much. mm! much more useful, and i think more practical, are robots that can roam our world doing the more mundane stuff like sweeping the roads. here's a concept robot mooting the idea that if you're going to go off grid, you might want a solar panel on wheels that follows the sun like a sunflower, gradually charging its batteries so that you can then run your camp, your car or anything else you've got knocking about that's electric. i'm going to build my own robot. itri is taiwan's industrial technology research institute, and i'm trying out its new modular robot design, which involves quite a bit of twisting. talk amongst yourselves. to be honest, you could get a robot to do this bit, couldn't you? a typical production line might need several different types of robot, but this prototype has interchangeable joints so you can build and alter your bots as you move them. i thought i'd crossed the thread then. in which case we'd leave quite quick and let them sort it out. this means you don't need to bring in specialised robots if you only want to make a small batch of items. and if something goes wrong, you can swap out a faultyjoint without having to shut down the whole arm. there — i've built myself a completely useless robot arm with nothing on the end. you're welcome. baby voice: daddy! deep voice: yes, my child? dog whimper effect. i'm just waiting for my next guest in this robot—themed section. don't know where it is. oh, my... oh, my gosh! spencer laughs. this is hi, a remote—controlled prototype from chinese company unitree. i've seen this outfit at a couple of tech fairs now and, although boston dynamics has won youtube with its amazing dog and humanoid bot bits, this is a reminder that this kind of tech is not unique any more. h1 is nowhere near as advanced as some, but it does have the basic balancing skills, which means it can certainly handle some action from a kid from the mean streets of vegas. all right... i've always wanted to do this. spencer laughs. i think it's time to exit, stage right. right, 0k. right. ok. he's not happy about that. # oh, well, bless my soul... and that's it from here for now but, like a vegas buffet, there is way too much for one sitting. trust me — i've tried. so we'll be back at this crazy place next week. you do not want to miss it. see you there. see you there? see you there. excellent. # i'm all shook up #. hello. today and tomorrow brings a window of quieter weather for many, which is good news, of course, for the easter weekend. not completely dry, there will be a few showers around, but fewer of them. with a bit more sunshine, it should feel warmer for many for a time before things change as we go into monday, especially across england and wales. at the moment, the low pressure which has governed things so far, the centre is out to the west, this is where the focus for the heaviest showers are, but we have been drawing up cloud across east anglia and the south—east. this is where it's been grey so far today for some. brightening up through the rest of this afternoon. there will be a few showers around, particularly across scotland. some heavier ones out towards the west, a rumble of thunder, but through much of southern scotland, england and wales through the afternoon very few showers. more of you will spend the bulk of the day, if not all day, dry. as i said, temperatures a little bit higher than recent days at 10 to 14 or 15 degrees. into tonight, some thundery showers across the channel islands and the south—west pushes towards ireland. a bit more of a breeze here. that will stop temperatures dropping too much. with lighter winds and clearer skies, central and eastern scotland, north—east england, this is where we could see frost to take us into sunday morning, which of course is the start of british summertime, so get ready to put the clocks forward an hour tonight. it does mean tomorrow evening the sunset will be an hour later, so some longer afternoons and evenings ahead. as for easter sunday itself, well, for many it starts bright. there will be the chance of showers first thing across ireland. more of those could be heavy and thundery, but a greyer day through central eastern england, and especially along the coast. it could be quite misty. that is drifting its way northwards into eastern scotland later. a bit more cloud through central england. a few showers elsewhere, but a lot of dry weather. the best of the weather across scotland and in the west we could see highs of 15 or 16 degrees. with easterly winds here on monday, this is where the driest, brightest weather will be, but low pressure in the south brings a return of some more widespread rain drifting northwards through the day, breaking up into showers. some of those in the south—west could be heavy and thundery later. we will get a bit of sunshine, though. we could see temperatures at 13, 14 degrees around the london area. a cooler day in eastern scotland, north—east england with a breeze off the sea, but western scotland again in the sunshine, it could get to around 13 or 14 degrees. a quick look at some of the charts to take us into next week. if you're on an extended break, of course, with it being easter, low pressure rules the roost. don't take the weather symbols too literally. there will be rain at times, breezy as well, but it won't be desperately cold with temperatures a little bit above average. live from london. this is bbc news. the us is said to have authorised billions of dollars worth of arms to israel and as the un warns of imminent famine in gaza, our correspondent joins a us aid drop. they're just opening the hatch ready to release the aid down into gaza. there is no organised distribution system down there. there it goes. further political instability for northern ireland with the resignation of the democratic unionist party leader, sirjeffrey donaldson. he says he will strenuously contest historical sexual offence charges. power blackouts in seven regions of ukraine after a wave of russian missile strikes, the second large—scale attack in a week. and a treasure trove of never—before heard music from the late singer marvin gaye has resurfaced in belgium. hello, i'm sarah campbell.
