to power in 20 years. oh well that's it for now. after short break, our technology program shift will take a deep dive into virtual reality. remember, you can always get the latest news on our website, d, w dot com, a michael, look for me in the entire news team here in berlin. thanks for watching and do stay with d. w. ah, with these places in europe are smashing the records. stepped into a bold adventure. it's the treasure map for modern globetrotters. discover some of you up to record breaking sites on google maps, youtube and now also in book form on the green with.

do you feel worried about the planet we to i'm neil. host of the on the grievance of cost, and to me it's clear we need to change the solutions or out the join me for a deep dive into the green transformation for me to do with, with hanging out at the beach without needing to book a flight or hotel sounds pretty good, right? 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 and virtually flow through space or kill launched us,

but at virtual reality is about to take immersion to the next level. developers are 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 over most or reaching out and shaking hands with someone else in the matter of us. virtual reality developers of working on making all v r experiences warren, massive 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 a fundamental issue because the way that we interact with the real world is, is driven by a server or sensory merchant system. so we, we are actively gathering information from the world or august to interactions and that,

that is the key thing will be our to the university of chicago is even looking into so called chemical happ takes. this wearable contains an integrated many pump, which transmits chemical substances under the skin that match a given d r experience. the researchers have identified to find substances that cause specific sensations, all of which is said 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, and this is

a teacher loud since everybody devices are probably the sort of short term solution to do b and b r one full body shoot is the tass 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 degrees celsius. that's pretty incredible, but the sued also cost several $1000.00 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 ap, 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, snell, and object directions make the v r illusion. especially convincing that 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 trouble. you can claim the famous whitman to the matter or bungee jump of a new york statue of living. there are certain experiences that you can get you in a virtual world that would be impossible and any otherwise. and those that's why i think this is an entertainment service back b, r is a real sort of game changer getting last into a world you otherwise would not have access to the r 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 for emergency responses, such as

a fire in the tunnel. the russian academy of sciences even similarly took an entire moon mission using the yard the real value of the training that you, you get to experience situations that might happen very rarely on the never happen in your life. so for example, senior meeting raster social cases that perhaps a surgeon my own, yet a lot greater unless if you're able to simulate that you improve intimacy is a, is, is going to be a game changer for, for health care. 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. all 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 . suppose. but every one knows a real experience involves more and bouts of our brain receives input from all of our sensors and looking at combines, if you see the cuts, examine how our brain reacts to viani strongly depends on how many of all senses osteo 8 it studies on rats showed that when they were placed in sympathy, our surroundings only 40 percent of than euro pathways were active compared to real life. the more realistic, the v r 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 v all similarly to how it would really experiences my definition. the 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 enter that when and the real world from fear to gratification. the physiological responses resemble each other. oh, trait increases, skin conduct 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 meadows new mixed reality had said inter, 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 mit reverse. thanks to the latest the are headset which track users i'm with the headsets use harmless, infrared light to ascertain where user is looking. the addition means, avatars can make eye contact. plus, operating menus are aiming at objects can now be done with i movement saloon in v r

e i tracking tech should also help speed up your gain, griffin. 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 lacking a rendering right now e, i can't reliably predict where user to connect. so currently little computing 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 he's medications for months 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 od 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 in real life. 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 develop the help of the crowd funding for just a few 100 years more. you can get the swivel chair to get the feel comfortable. i'll be unexpected. with that in the metaphor. serious v. r gamers, me also be interested in treadmills. we 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 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. clearly 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 youtube or by email by and see you soon? ah

ah, the war has forced more than 4000000 ukrainians. tiffany: their country, like let's say 300 business owner who left his company and employees behind people who continue to rely on him for a salary. will his enterprise be able to survive the war? a d w business special quickly on d, w. o. o long does a war and eternity time . it can be measured precisely. indeed,

every one experiences it differently as if there are different forms of time. time, a phenomenon, a dimension. if we know we won't live forever, an illusion. about time presenting futures past starts april 14th on d. w. ah . abandoning nearly every thing a fate death, millions of ukrainians have had to encounter so far. on the show, we meet a filmmaker who managed to flee the war and is now worked not only about his business, but about the lives of his employees to 70 percent or fail in the crate or against some of them.
