can you hear me? hello? yes, can you hear me? are you muted? no, are you frozen? all i'm getting is me back. i can hear me. hang on. sorry! hang on! what have you done? have you dropped the phone? yeah, sorry. i can hear you now. hello? you've got me? yes, there we go. i'm more used to talking to you like this than in real life now. yeah, and i'm more used to talking to you while you're walking up and down wherever you're going. did you know that a fifth of all zoom meetings last year took place while people were walking and running? and i reckon that's all you. all me — just think of the steps!

but many people have been doing it a bit more horizontally. don't know what you're talking about! but listen, love �*em or hate �*em, these platforms really have kept us together during these tough times, haven't they? and i don't think they're going away any time soon. it is some way towards seeing people properly, but of course it is not the same, especially with strangers, it can be a bit awkward. yeah, you think of the people that have joined the click team in the last couple of years. i mean, for a long time, they didn't know how tall we were, they'd only ever seen us from the waist up, they couldn't enjoy our sparkling company in person! lara chuckles but this is something that the big tech companies are addressing, and some of them are coming up with completely new ways to collaborate online. here comes osman iqbal with more. hi! one thing is certain — the future of work is hybrid, which means we need to start working out how to best collaborate between the real and virtual worlds. for nearly two years now, i've seen my colleagues on this screen. but that's so 2021! because, brace yourself. ..for holograms.

this is cisco�*s webex hologram. ijust need to put on this headset and a life—sized cullenjennings, who's based over 4,000 miles away, will appear in my study. hello there, cullen! hey, good to see you, oz! how are you doing? i'm very well! so, it turns out that it's pretty hard to record a 3d hologram for tv. those black pixels around cullen weren't actually there during the call. you can go grab it here too as well and move it around. just reach out and grab it. oh, get out! right, i've got it! i've got it! it's in my world! i don't know if this will ever came across on screen. in a way, i should be amazed by the hologram. see that — see that is cool, that is. but really, it was the passing of those cad objects — that's the thing — the thing that really blew me away. it's one of the areas that i think this will be used a lot

is when you're trying to do these design reviews, understand what people are building, see something, see a part that you were designing and those types of issues. we are betting on the hologram as being the next big kind of immersive medium of communication. just for ease, to kind of help you out, make it a bit smaller. there you go. oop. what the hologram does is exactly the opposite of what others are working on, for example, with avatars, but what you want to do is make it very photorealistic, you want to make it very lifelike. wasn't expecting that. there we go. oh, that's terrifying! and what the technology that we're talking about and that we're working on does is fundamentally levels the playing field, so that an individual in a village in bangladesh has the same opportunity as someone in the heart of central london. say hi to auntie! oh, my gosh! i love you! and with other concepts like google�*s project starlight in the works, holograms may be

with us sooner than we think. but for most of us, video calls will remain as our standard way of communicating, so nvidia have been using artificial intelligence to solve those day—to—day problems. and staring at a screen during an endless meeting is definitely an issue, so gaze correction can make it appear like you're always looking straight ahead — something that seems minor, but is actually really important. let's say you're in an interview and you want to sneakily read some notes. or even in a not—too—interesting meeting, you canjust look like you're paying attention. right. left. another obsession sweeping through the tech world is the photorealistic avatar. this handsome chap can even track my expressions in real time. it freaks me out a bit,

but let's see what the team thinks. have you ever seen max headroom from the �*80s? i have not. i recommend you check it out because you're basically him. but those rugged good looks may be intimidating for some. yeah, i'd rathertalk to real people, i think. call me traditional! and whilst not as sci—fi, one vitally important thing that nvidia claims they perfected is removing all the background noise when we're talking on calls, no matter where we are. siren wails i persuaded the company to let me try this in the wild. fire engines, ok! anotherfire engine! bus engine hums: all right, richard, there is a big bus going by — can you hear me? 0k. n0 bus noise: all right, richard, there's a big bus going by — can you hear me?

no, i hear only you! you keep saying there's all this noise, but i don't hear it! the smart gallery creates individual video feeds. but the big question is — what's zoom doing? theirfocus is now on using hardware to create hybrid video—calling solutions, like installing cameras in meeting rooms to enable in—person and remote participants to interact. right, and that's our mindset at zoom. it's like, you know, you can come up with a marketing video that talks about the metaverse and says, you know, the world's all going to be holograms some day, but what are you doing for me today? chuckles i have real problems right now that i need help with and ijust want to be able to talk to my colleagues around the world, whether i'm in the office or i'm at home. can you help me with that? you know, rewind back a few years ago and it was — mindset was "i have to be in that room to be effective" and remote people are second—class citizens, it's very challenging to break in, it's very challenging to be heard. it's...

they may just forget about me up on the wall. and now, it's reversed again, so how do i maintain my individuality when i'm in a group meeting space? where am i? where are you ? over here. come with me. but maybe we don't need avatars and virtual reality to get back that real—life office feeling. it could be as simple as this retro—looking platform, gather, where you can wander around and bump into colleagues. so, in the right virtual setting, maybe the chaos of office life can live on. half of my team have disappeared. can i interrupt this meeting to point out we've just found there's a rooftop bar. crosstalk hello! so, am not i allowed to lock the doors? ok, admittedly, this

is a pretty sweet gig — see what i did there? the average american gobbles over 20 litres of ice cream per year, compared to the paltry seven for us brits. so i've come to the suburbs of boston to set the record straight. i'm actually here to see a new type of appliance reminiscent of those coffee pod machines advertised by george clooney. wouldn't change a thing. now, the way this works is that each pod has its own unique qr code, and when i put it into the machine, a camera scans it and tells the machine what the product is — if it's a cocktail, a coffee or an ice cream — how long it should freeze it for, and to what consistency. we're all set up for all kinds of stuff within the same space. andrea has invited me to the test kitchen to conjure up my very own flavour. 0h. it's good. yeah? yeah. imean...

what would you do to make it better? you can't improve this. you can't improve it? this is going straight to the shops. we're done. the ones that have been a struggle or challenge has been the smoothies, because we want them to be healthy. we're adding nutraceuticals, which are like plant — food ingredients that have benefit — nutritional benefit. creating a combination that tastes good, that's healthy, that's shelf—stable is a challenge. cold snap aims to overhaul the frozen treat industry from how food's made, to how it's stored, to how it's shovelled down my throat. the way ice cream is made today, it's frozen in the factory, it's kept frozen in the grocery store, you rush it home, you keep it frozen in your freezer. all the while, you're putting energy and cost into that pint of ice cream before you consume it. there's a lot of carbon emissions associated with that that's going up into the atmosphere. our technology, with cold snap, we just freeze it when we need it, and so, we think we can reduce the carbon emissions associated with making ice cream by, like, anywhere from 50% to 75%. it could mean less waste, but will come with a hefty price tag of around $2,000 — or £1,500 — but is initially aimed at the commercial sector.

cheers. everything has been designed from scratch, right down to the unique caps on the pods. we wanted absolutely no ice cream touching the machine. we wouldn't be able to use a regular soda can style, so we developed our own top. the aluminium cans are important because they can be recycled, but they also allow for good heat transfer, so the liquid inside can be chilled quickly on demand. by being able to churn the ice cream and draw air into the can as it's freezing, you can actually create the ice cream. at the risk of stating the obvious, the technology actually affects the taste of the ice cream. we're intentionally making the ice crystals smaller than anything you can buy on the market today. so it's — in addition to being 14% buttermilk fat, we control the ice crystal size, and you essentially get a very dense, thick, creamy dessert. i guess you could say the proof is in the... ..pudding? but is this one machine too far

in the age of convenience? do we really need this? then again, do we really need ice cream and frozen cocktails? ohhh, it's been a tough day. oh, it's enough to make you feel hungry, isn't it? ohhh. and, conveniently, we can eat something now, because that's it for the shortcut. the full—length version of the programme can be found on iplayer. and don't forget you can check us out on social media any time you fancy. we live on youtube, facebook, instagram and twitter — @bbcclick. thanks for watching. and we'll see you soon. bye— bye. hello. a little bit of brightness to end the day across some parts of the country.

but overall it was a cloudy day with rain at times, and the week ahead is also looking very unsettled, as this powerfuljet stream is expected to send multiple areas of low pressure in our direction — that means bouts of wind and rain, and actually, from midweek onwards, some of these low pressures could be pretty nasty, bringing the risk of some quite stormy weather across northern parts of the uk. you can see those strong winds blowing out of the west — it'll actually be relatively mild, in fact, midweek across some southern parts of the uk, temperatures could even reach around 15 celsius. so yes, low pressures bring wind and rain, but they also can bring some very mild weather, too. let's have a look at the short term, then — so through the early hours, you can see some clear skies there across some northern and eastern areas, but the next low pressure is approaching. weather fronts sweeping in the wind and the rain to some southwestern and western parts of the country. mild in plymouth and cardiff, around nine celsius,

a little bit colder there in eastern scotland, perhaps close to freezing in the glens. so the weather map shows a low pressure crossing the uk during the course of sunday. it will be wet right from the word "go" across many northern and western parts. i think east anlgia and the southeast may have some brightness early in the morning before that rain reaches you later on in the day. and there's also a chance that later on in the day, skies may clear, and you might get some late brightness around western parts of the uk. but the north of scotland should stay dry and bright all the while on sunday. and here's sunday evening — you can see that rain dragging its heels across the south of the country, it'll probably stay wet all through the evening and into the early hours of monday. here's monday's weather map — low pressure out in the north sea, that means a cold northerly across scotland and along the north sea coast. it will feel pretty baltic, with the wind blowing off the north sea.

some showers, for sure, the best of the weather will be out towards the west and the south. here, temperatures will be around, say, at best ten celsius, but six celsius in the northerly, and newcastle is pretty chilly indeed. bye— bye.
