this is bbc news. we will have the headlines and all the main use stories for you at the top of the hours straight after this programme. this week, medicines, make—up, and marker paint. hey, welcome, welcome, welcome.

today, we are going to be talking about gaming. what was the last game you played? does wordle count? yes it does. i got it in two in my first ever go. i'm quitting while ahead. i'm never playing again. wow, very wise. show off. in our house, it is mainly... and a fair bit of... and quite recently, a little bit of... engine revs. crash. now, look, we all get sucked into the latest game at some point, and we end up playing it just a bit too much. yeah, for most of us, it is just a harmless pastime or a bit of entertainment, but for others, it can be taken too far. now, marc cieslak has gained exclusive access to a new treatment centre for video game addiction. many of the teenage patients have an obsessive desire to play, and almost all of their social interactions are about gaming. and, in fact, if their consoles are taken away, it can lead to violent outbursts and confrontations with parents and carers, and sometimes even threats to take their own life.

for us as a couple? it has been challenging, in as much as it is quite difficult to have interaction outside of the house, and even having people around, you feel a degree of embarrassment sometimes. i mean, for the duration of the visit, he'lljust be gaming upstairs all the time, shouting and cursing. for us sleeping has been a huge issue, so often that we'll sleep in separate rooms. and i'll have to have the fan on to sort of drown out his game. stephen and louise are describing life with their 16—year—old son who suffers from gaming disorder. those aren't their real names, where protecting their identities. it is a controversial condition, defined by the world health organization by three characteristics — impaired control when gaming, prioritising gaming over other interests, and escalation of gaming despite negative consequences.

the games industry and some psychologists question the evidence used to define the disorder. until quite recently in the uk, help for problems like this could only be sought via private health care. the nhs has created a specialist clinic for treatment of the condition via therapy. phone rings. hello, thank you for calling the national centre for gaming disorder. we've got four people, four under 16's parents... based in west london, it is part of the national centre for behavioural addictions. this is the first time cameras have been allowed to film inside the gaming clinic. we know that gaming disorder is quite a rare condition. so, the symptoms of gaming disorder can be really quite severe, which has surprised us. they can struggle with anger, anxiety, and low mood. often, they also experience physical symptoms, in terms of loss of sleep, and that is often because people will be gaming at night to connect with gamers abroad. yeah, so we need to think

about the groups that we are going to start in the new year. this is the only nhs clinic in the uk treating gaming disorder. its patients are spread out across england and wales, and are often treated via video chat, something they have been doing here since way before the pandemic made the practice commonplace. video games are a massive pastime and source of entertainment and connection for people. but when does the amount of time spent playing across the line into problematic behaviour? a recent study concluded that broadly speaking, playing video games is actually good for most people's mental health and well—being, and that playing games has helped lots of people get through the pandemic. so, we're not saying that gaming is bad at all, we completely accept that for a lot of people, it is a really positive thing in their life. we are really talking about that small percentage of people who are having

a massive problem with it, and it is genuinely affecting their quality—of—life and their ability to interact and their ability to function. we opened our doors at the end of 2019. we have had well over 300 referrals since then, 200 just in 2021. we start treatment at 13. we've had a few 12—year—olds who have been referred. we have also heard from people as young as eight, or parents of people as young as eight but we haven't been able to see them. and the age of people being referred to the clinic goes right up to the 60s. it is very strongly weighted in favour of males, so we have seen 89% of people who have been male. stephen and louise's 16—year—old son has recently been diagnosed with autism. his issues with games have been ongoing for several years and sometimes lead to violent episodes. a recent outburst resulted

in a police intervention when their son physically assaulted stephen. they referred him to the gaming disorder clinic themselves, but he hasn't engaged with the treatment. what was most helpful for us was talking to other parents. they made a special support group for parents of the same gaming needs or addiction or whatever you want to call it, we meet once a fortnight on zoom to discuss how we are doing. and more than anything else, i think the greatest thing about that, in terms of benefit, is to realise that you're not alone. there are loads of other people up and down the country and all across the world that are going through exactly the same situation. what do you think the future looks like for your son, and what you think the future looks like your family? i feel optimistic because on facebook, ifollow a lot of people who are very like our son but they are adults now. and i follow them because they are hugely insightful but also it really helps me feel he will find his way. that was marc, and of course, mental health issues aren't always immediately visible. if you were affected by anything you saw there in the report, if you are in the uk

you can find support at bbc action line or internationally at befrienders.org. now, whether it is mental or physical health, the nhs helps millions of people every day. and that means it has to move a huge number of medicines around the country. and one of the busiest distribution centres in the uk is not farfrom us here in glasgow. this centre processes 15—20,000 medicines every day, sending boxes to hospitals and wards across the glasgow area. it is a massive operation and this is how the filing system works. now, when the stock comes in, it gets loaded willy—nilly onto this conveyor belt. well, i have loaded it willy—nilly, anyway. and then it goes through that hole there. now, a little sucker picks up each box and twiddles it around in front of this sensor where a qr code tells the computer the dimensions of the box, the expiry date, and what it is, of course.

and then it gets dropped on that conveyor belt and sent to the main event. there are eight of these robot arms which sought the medicines and place them on to suitably sized shelves. then, as the orders from the hospital wards come in, they pick them back off the shelves in the correct combination and send them down the chute and the boxes are ready for dispatch to each ward. the popularity with medicines change because in the summer months, you might have more antihistamines being getting used than we do in the winter months, and cough syrups more in the winter months. so, it stores a bit of history and it knows, based on previous outputs, when the trends arise and it will know to then move it closer to the output. now, the software doesn't put all of one type of medicine in the same place. it distributes it all over the place and it tries to get the medicine that is going

to go out of date first closest to the output conveyor belt. but once it has picked those, their newest stuff goes in there and everything goes a bit out of order and so during the quiet moments, the robot does a bit of housekeeping, kind of sorts out its medicine cabinet. now, this isn't brand—new technology, but it has perhaps become more relevant since the pandemic. as with many health systems over the last few years, the nhs is suffering from a huge patient backlog, and when this technology was introduced, it had a big impact on where people could be deployed. previously, a lot of the pharmacy staff were based in the pharmacy department and the hospitals. this area then became centralised and we released the pharmacy staff to the pharmacy ward areas. so, it may be that using more robotic systems like this could free up staff to work directly in patient care where the human touch can

really make a difference. hello, it is time for your weekly 90 second tech round—up. it was the week twitter will expand its safety mode feature which lets users temporarily block accounts that send harmful or abusive tweets. dating site tinder goes retro and introduces blind dates for users to interact without profile pictures. and disney is the latest massive corporation to show interest in the metaverse, appointing long—term employee mike white as senior vp for next—generation storytelling and consumer experiences. meta, the company that owns facebook, is to pay $90 million to settle a privacy lawsuit over tracking users without their knowledge. the social media giant who this week rebranded its newsfeed denied wrongdoing but settled to avoid the costs and risks of a trial. next up, if you want to know exactly how stressed you are, new wearable tech that looks a bit like a smartwatch

can tell you. researchers at ucla made this device which uses sweat to monitor the level of cortisol while being worn. and, finally, more private astronauts are hoping to boldly go up but this time outside the spaceship as billionaire jared isaacman filed flight plans that include the first ever commercial spacewalk. the finance ceo is already a crew draken veteran, flying last year on the inspiration 4 mission. the polaris dawn mission hopes to test new eva suits and raise more money for stjude�*s children's research hospital. watch this space. this can is filled with a forensic spray which for the first time is being used to stop domestic violence. to show how it works, i volunteered to be sprayed with it.

you can't see it with the naked eye but switch on the uv lights and you will see i've been marked. for years, the substance has been used to protect property and deter thieves but now for the first time it is being used to convict someone for harassment. a man in wakefield, west yorkshire, has been jailed for breaching his non—molestation order. he had been told to stay away from his ex partner and her house so when he turned up, she sprayed him with the solution. three police forces in england have been giving these canisters filled with a smart water to victims of domestic abuse, harassment, and stalking. and if it is sprayed on a person, it can put them exactly at the scene of a crime. each batch at the liquid has a unique formulation. at this lab in telford, they mix together different chemical elements and there is more than a billion possible combinations. the technicians can analyse the tiniest of samples so from just one drop of this stuff, they can tell exactly what bottle it came from.

well, i can't tell you the secrets of the smart water but what i can tell you is that it is made up of a combination of rare elements that would never be found naturally anywhere else in the world. each batch is unique. we know that categorically that smart water was registered to that person and can be linked back to the scene of the crime. what about cctv, would that not be a good enough deterrent? cctv might not identify that categorically that was that person, particularly if they were wearing something like a balaclava. suddenly, the element of doubt is there and you cannot categorically prove that, whereas there is no element of doubt in something like smart water. the idea has been around for a while. it featured on the bbc back in 1996. but using it to deter domestic abuse is a new idea and police say it is working. this is what forensic marking is doing. what we are saying to the perpetrator is if you go back to that address and you breach these conditions, if you commit offences, you will be forensically marked,

we will be able to prove that, as a police service, and we will bring you to justice as well. how pleased are you that you got the conviction here in yorkshire? during that incident, the victim was able to safely deploy that canister during an incident at her home address and during the subsequent investigation, we could forensically see that the individual was marked with the spray. the following day, the perpetrator was convicted and received 2a weeks imprisonment for the breach of the non—molestation order, which we are really pleased about. over 200 women across the uk now have smartwater in their homes and the majority of them are telling the police that they feel safer as a result of having the tool. they are also saying that their perpetrators are not visiting them any more. the victims say that they can go out to work and just have peace of mind. currently, west yorkshire, south yorkshire, and staffordshire police forces

are using the tech as part of their domestic violence strategy. but it is thought that forensic marking will be trialled by other forces across the country, too, in the hope of securing more convictions and deterring more crimes. now, this week is london fashion week. once more, models are gracing the catwalks to show off this season's finest designer garments. have you seen anything you like, spencer? not sure. yeah, it is all a bit experimentalfor me, shall we say. but it looks very creative. how about you ? well, don't laugh yet but i have actually been on the runway this week. i'm off to that fashion innovation agency at the london college of fashion to test out a motion—capture rig unlike any i have used before. no expensive mocap suits here,

no dots painted on my face either, and no professional motion capture cameras. with this system, you don't need any of that, you can track all the way down to finger level detail just using camera movement, and the outfit you are wearing, at your own convenience. usually, the team here would be capturing proper models but today my body is being motion tracked. action cams — check, gaffer tape — check, one truly awkward click presenter — check. first, i need to calibrate the system. and we are good to do some motion capture. flex those hips, swing the arms, give me a pose. stop. pose for the camera. love it. turn around, let's do the same. amazing. strike another pose. i don't usually get camera shy but suddenly i don't know how to walk. there is definitely not a job for me in modelling. this technology in particular

keeps the models relevant. you need to capture that human data, you need to capture that natural movement, their nuances, their body language, their posture, their gesticulation, the personal space, it gives you a sense of that person in that space. so, even if the avatar doesn't look like you, people can still look at it and be, like, that is your walk, that is the way you stand, i know that is you. it draws you in, it keeps you immersed in the experience and makes it more believable and enjoyable, as a consumer. what we've built on top of the ai are a number of processing engines on top. we have biomechanical rules written into them so there so there are kinematic models, holonomic constraints which are what the human body can do, in terms of how the joints can move. so, for instance, if i bent my elbow like this, you can't bend it past a certain point of extension. rules like that are written into the system. we can work out where your feet are, and when you are moving around the volume, what that allows us to do is basically create a map of the volume and you within it. there are six cameras in this setup, and that is enough to track about five people in this space, although they may bump into each other a bit.

but it can be scaled to whatever size you want, and you can choose the resolution. so, for example, if you were to use a football pitch, it could track about 22 people. the reason we can scale that up to a football—sized pitch, for instance, is we up the resolution in the camera to say like 12k, and they can be much further away and higher up but still maintain that pixel density of the person. the system isn't live. videos need to be filmed and then processed first so it is ready for 3d garments a few hours later, but the workflow is getting faster. there is a huge amount of money being generated now through virtual garments that don't exist in the real world, but what has the reaction being to that from some of the old—school fashion brands that would probably prefer everyone just wearing real clothes and they go and look at them on a real catwalk? i think that fashion brands are starting to understand that they are addressing a consumer who doesn't only exist in the physical realm, and by using these kinds

of technology like motion capture, we can kind of curate material layers that we can use in the digital realm. the avatars look amazing. costas thinks that the tech being developed now will be important to the future. there will come a point where we will be able to consume digitalfashion more realistically and in everyday life, and i think that these kinds of technologies allow us to kind of get there quicker. kate moss, eat your heart out. you're a natural! and now, from clothes that you can't actually wear to make up that you can't really see. here is nick kwek. i'm really fascinated by all of those worlds that exist beyond our eyes, ears, nose, and mouth, and what we can sense as a person. renowned for creating chameleon—like clothing that changes colour depending on the wearer's environment, lauren bowker and her team are now turning their test tubes towards

the beauty business. we just launched our metaverse make—up spectra and essentially it isjust a colour and make—up and an eye colour that transcends the digital physical reality. they've made a real world make—up intended only to be seen virtually. the eye is a window into your reality, right? it is how we see this physical reality that we are within, but the screen is also another eye and another medium in which to view a different reality. so, this is the metaverse make—up here, and when i apply it to the skin, you can see it disappearing. it is almost invisible. but it comes to life when i pull out my smartphone, turn on the flash, and, look, there you can see it. look at that. the product itself is retroreflective so it reflects into a spectrum of light that we tuned for the mobile phone flash camera to be alive in the metaverse. ifeel like i am literally in the future right now.

spectra wasn't designed for everybody on the planet, it was purely designed out of curiosity. and curious it is. infused inside the make—up is a special ingredient made from glass micro spheres coated with aluminium. it works a bit like the coating on road signs which reflect car headlights. yeah, gorgeous. i feel great. in my sci—fi fantasy. my first metaverse photo shoot. the inspiration came from being at a gig and watching everybody at the gig view that gig through their phones. watching everyone watch that musician through the screen made me think what if we could create a colour that exists in the physical space but is only seen through the screen in the digital space? yes, looks really good. why would someone who wants to wear make—up not want people to see them wearing make—up?

why would they not? isn't the most interesting thing about someone that think they don't tell you? or the thing they don't show? for me, that is the most interesting thing. i wear a lot on myself because it is quite fun thinking that people don't know that you are actually wearing it but you know. it gave her a moment of expression that was unseen, just for her. it is like your own little secret, you know? is the world ready for this make—up? i think the world absolutely is ready for it, but it won't be for everyone, and it is not meant for everyone. well, let's see. it's time for me to face the make—up. do i look ready for the metaverse? time will tell. oh, yes. i think he looks lovely, don't you? he normally spends most of his timejust doing his hair.

oh, that is true, that is true. anyway, that was nick and that is it from us for now. as ever, you can keep up with us on social media, find us on youtube, instagram, facebook, and twitter @bbcclick. thanks for watching, we'll see you soon. bye— bye. some of us are still feeling the effects of the storms. we are flooding in places. how about the weather in the short term? well, it's not going to be a bad start to the day for many parts of england and wales. but for scotland, northern ireland and to an extent the very far north of england, it is going to be once again a very blustery day on wednesday and it will turn progressively wintery through the day. it is still very active

on the satellite picture here. these weather fronts across the atlantic racing our way. all of this, this is wintry weather, linked to this low pressure. a cold front is approaching but to the south, we are under the influence of a high—pressure here. so, clearer skies, lighter winds and through the early hours of the morning, a touch of ground frost at the very least in rural areas. city centres itself won't be that cold, 6 degrees in plymouth, pretty nippy enough in birmingham at 2 celsius. milder, slightly milder weather there the morning in the lowlands of scotland and northern ireland. now, here's the next low pressure that is coming in. a cold front and behind it, we have wintry showers. the morning is going be pretty soggy in northern ireland and scotland, with increasing winds and gale force winds and 60 mile an hour gusts. the weather will eventually go downhill in the far north of england too. particularly blustry in the northeast there in newcastle, but all the while there, new england and wales, but overall not a bad day. increasingly through the afternoon we will see winter showers and scotland and northern ireland

to lower and lower levels. and then that takes us into wednesday night and thursday. that cold front crosses the country and then we are all in the blustery, chilly stream of air from the north atlantic and you can see how frequent the winter showers are across northern ireland. some showers could be wintry also across england and wales, maybe not the extreme south and in fact, if anything, thursday should be a decent enough day. single—figure temperatures. it will certainly feel coldest and the northwest here. 5 degrees and you add on that gale—force wind and you'll feel like it's barely above freezing. there is a hint of better weather on the way as high pressure builds on friday. i think that's going to be a very decent day and perhaps into the weekend, some of us could hold onto some that better weather. goodbye.
