tops run for more prominent roles. you're watching d. w. she's your reminder of our main story. ukrainian president vladimir zalinski says a russian missile attack on a train station in eastern ukraine that killed at least 50 people amounts to war crimes. a president is demanding more weapons and a tough global response. after a short break, sports life is next. please stay with with how long does a moment a war and eternity time . it can be measured precisely. and did everyone experiences it differently

as if there are different forms of time? time? ah, the phenomenon a dimension. if we know we won't live forever. an illusion. about time presenting futures past starts april 14th on d. w. hanging out at the beach without needing to book a flight or hotel. sounds pretty go drive. especially if you could actually feel the water and sand a futuristic dream. well, not necessarily how good is varieties days. that's our topic on shift today. ah. most of you know that video headsets, you can virtually flow through space or kill launched us. but at virtual we,

it is about to take immersion to the next level. developers out in a raised to make it even more realistic by incorporating more of our sensors like touch. the new buzzword is happy. we are picking something up with your hands, running your fingers open, most of reaching out and shaking hands with someone else in the matter of us. virtual reality developers are working on making all v r experiences more immersive and thus more realistic. but this is no small feat, so there are a number of outstanding challenges. first and foremost is this optics. that is, there is a fundamental issue because the way that we interact with the real world is, is driven by a server or sensory motor system. so we are actively gathering survey information in the world are august to interactions, and that is the key thing will be our to the university of chicago is even looking

into so called chemical hap tics. this wearable contains an integrated mini pump, which transmits chemical substances under the skin that match a given d r. experience. the researchers have identified 5 substances that cause specific sensations, all of which are set to be homeless and small doses. for full body haptic feedback company such as tesla met an amazon on developing suits so that uses can feel touch force and thermal feedback on their entire body. this would make the on training more realistic and thus better at engaging on muscle memory. but it will still take a while before such suits become readily available. i imagine it probably will be a, we're a day where we are. we do have that's the reality of so body suits and so, and monte displays. but in the civil feature glowed sensor rubacheck device,

probably a short term solution to do a, b, and b r one full body should is the task lawsuit which provides tactile feedback through electoral stimulation. it can even recreate the feeling of rain on skin or temperatures, arranging from $20.00 to $40.00 degree celsius. that's pretty incredible, but the suit also caused several 1000 euros. a cheap option. i have to gloves, like the ones being developed by meta. these simulate the feeling of pressure on your skin, which isn't just useful for playing games, but even without happ, thanks. current we are is already impressive. so long as you have the right equipment. games are still the largest market for v r and right now, 40 games in which a player can move freely in the room or especially popular warmth, wind, smell, and object directions make the v r illusion. especially convincing. but v r can be

used for much more, such as a museum visit, include stepping right into a painting or a virtual vacation. in spite of pandemic travel restrictions, you can claim the famous whitman to the matter or bungee jump of a new york statue of liberty. there are several experiences that you can get you in a virtual world. there would be impossible and any otherwise. and those that's why i think this is an entertainment service. betty b r is a real sort of game changer getting last ensure that you otherwise would not have access to vcr and e. r technology are becoming more interesting for other fields. in areas such as medicine, the tech is playing an ever larger part in education and training. the are is especially useful for practicing rear procedures or emergency responses such as

a fire in a tunnel. the russian academy of sciences even simulated an entire mission using beyond the real value of the training. that is you, you get to experience situations that might happen very rally on the never happen in your life. so for example, senior teaching raster social cases that perhaps a surgeon my own, you have a lot greater unless, if you're able to simulate, you improve infinity is a, is, is going to be a game changer for, for healthcare. practicing operations and v r is clearly useful, but how well do surgeons learned in vietnam? what actually happens in our brain when we are in a virtual world? and what other effects does be i have on the body, our brains process,

real world and virtual world information. through all senses. for example, all hippocampus is involved in spatial navigation. it creates cognitive maps that help us understand our surroundings. thus far via has been a primarily visual experience. dizziness image dark says this site is the most important to us and it would be much of our brain is dedicated to processing visual information, which is why it's normally enough to create primarily visual environments auditing . supposed. but every one knows a real experience involves more and bouts of our brain receives input from all of our senses. and liquor combines, if he says it cuts, examine how our brain reacts to viani strongly depends on how many of our senses i'll still ate it. studies on rats showed that when they were placed in sympathy, all surroundings only 40 percent of than euro pathways were active compared to real life. the more realistic that we are experience, the more similar the brain activity became. in an experiment where rats were put on

the, our treadmills, their brain activity closely resembled brain patterns they have when they run on treadmills in real life. this shows that the more immersive, the experience, the better our in response. if what we hear, taste, touch and smell doesn't match what we're seeing in via then the experience feels less real and will also learn less well. nonetheless, the brain does try to process the are similarly to how it would really experiences my definition. he, most of you and get him out of the brain. patterns are actually quite similar, that is, so a feeling of anxiety is process pretty much the same in a virtual anna that when and the real world from fear to gratification the physiological responses resemble each other. oh, trait increase is skin conduct to the changes. a bodies release hormones and

a reward center is activated, virtual reality can be fun. oh, and diety inducing. there are other ways to make the are more immersive cambria meadow's new mixed reality had said include what's built in front cameras, these film, the real world, and mix it with the virtual one, which can be useful for things like if you want to quickly write something down without removing that had said i tracking is also being used more and more for this special sensors inside the head said, track where the user is looking. this has a number of advantages. ah, i contact is no possible between avatars and the metaphors. thanks to the latest the are headset. which truck users i'm with the headsets use harmless, infrared light to ascertain where user is looking. the addition means of avatars can make eye contact. plus, operating menus are aiming at objects can now be done with i movement saloon in v r

. the i tracking tech should also help speed up your game graphics. oh no, is it human either this or that? the vision is a low resolution. so you can approximate a computing policy, dr. brenda, the full virtual. well, you can get render where the user is locking in rendering right now, e, i can't reliably predict where user the next to currently little competing time is being seen. however, it looks like that could soon change in, so i tracking is useful, but it also has downsize, our eyes produce highly sensitive data, which can be saved, analyzed, and sold research to say our agenda, age, weight, and even personality trades can be gleaned from i data was more they want the data

can be used to predict our emotional state drug consumption habits, skills, and sexual preferences. plus, that's another problem. this tech is affected by ethnicity and it's been found to be less good, a tracking asian people's eyes. we know definitely much of the research happens in western educated industrialized reach other countries. i'm not biased for when you're trying to develop a technology that is medications for you, man, yet, lot one body pod that the audio help us long overlooked our legs. there was no affordable leg tracking device for a long time, but that recently changed thanks also to kick started campaigns even once expensive the odd treadmills on now somewhat affordable these b r shoes are called act to one. they're still just a prototype, but they are the only shoes you can walk through the metaphors. well, almost moon walking, india like the shoes,

server motors go in the opposite direction to keep them crashing to a real wall. the so called cyber, she take a different approach. we were the help of the crowd funding for just a few 100 years more. you can get the swivel chair to the she's comfortable, i'll be unexpected. with that in the metaphor. serious v. r gamers, me also be interested in treadmills. they provide a different level of immersion. and they're also much more expensive with a price tag of around 1200 years. best in consensus tracking movement and your security to avoid being injured in real life while you're in p r. for those who can't afford or don't have space for a treadmill, there's the slain vcr full body tracker. is much cheaper option,

is probably the best value for money. that user should know. it doesn't stop you. so you may want to be weary of well. but be careful because be our home accidents are now a thing in the u. k. the insurance company, aviva said the average b r related claim for accidental damage was around 800 euros, think smashed tv sets, and they have also been serious injuries. communi, me, our safety isn't really safe yet. but what do you think? do you have a favorite variety vice a one you'd like to see develop? do you think other dangers are bigger or do you not care about v r and prefer to focus on real life as no one you tube or by email? by and see you soon. ah

ah, on you my grammy. he was that bad writer in scotland, austria changed quite a bit during the damage. what is it like winter sport in a former told it how thought check in with next to thought d w. whether it's like, what is necessary for all aspects of life. climate change is not just about computers. it's more than that draughts and floods in the himalayas. the feeling that by the youth and human people are you when he came back to by climbing chance because of the intersecting vulnerability. the weight of

the human cost of climate change in 30 minutes on d w. these places in europe are smashing all the records. step into a bold adventure. it's the treasure map for modern globetrotters. discover some of you up to record breaking sites on your mac, youtube, and now also in book form. it fits with. ah, ah, ah. in it's evening and is gill austria. it's peak season for the skew, resorted to roll, but there is not much going on, even though the co related curfew was lifted a few days ago.
