have this fear to, you know, just like for the revellers happy to be back out. octoberfest at loved. it seems beer really does bring everyone together and that's the latest unbeatable u. news of this our up next. our attack show shift looks at how virtual reality isn't just for gamey anymore. it's even saving lives. a marion evans, dina have more news for you at the top of the our thanks for watching people in trucks injured when trying to free the city center more and more refugees are being turned away at the border. families play involvement tax in syria to these credit owners with administrative people. lean,

extreme ross getting 200 people from the agency around the world. more than 300000000 people are seeking refuge. yes. why? because no one should have to flee. make up your own mind. d. w. made for mines 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 futuristic dream. well, not necessarily. how good is we are these days? that's our topic on shift today. ah,

most of you know that with our heads as you can virtually flow through space or kill monsters. but virtual reality is about to take immersion to the next level. developers 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. us virtual reality developers working on making all v r experiences warren, massive and us more realistic, but this is no small feat. so there and number about starting 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 it sort of a sensory motion system. so we are actively gathering information from the

world around to interactions and that that was the key thing for the our to the university of chicago is even looking into so called chemical hap tics. this wearable contains an integrated many public 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 harder, for small doses. so full body have to keep that company such as tesla, metuchen amazon on developing suits to that uses can feel touch force and demo feedback on their entire body. this would make the on training more realistic and that's 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 day where we do have that's the reality of so body suits. and so,

and monte displays. but in the civil teacher loud since everybody devices are probably the sort of short term solution to do a, b and b r one full body shoot 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 degrees celsius. that's pretty incredible, but the sued also costs several $1000.00 euros. a cheaper 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. karen, 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 gains 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 swiss mountains, the matterhorn or bungee jump of a new york statue of liberty. there are certain sort of experience is that you can get you in a ritual that that would be impossible and any or otherwise. and those that's where i think this is an interesting sort of the are the real sort of can change it, getting most into a world you otherwise would not have access to v 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. v r 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 thing is you, you get to experience situations that might happen very rally on the never happen in your life. so for example, senior meeting raster social cases that perhaps assertion my own year lock rate on on was if you're able to simulate that you improve infinity is a, is going to be changing jeff or for health care practicing operations and v r is clearly useful, but how well do surgeons learn and beyond 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 hipaa campus 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 thing is know 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 we can combine if he says of cuts. examine how our brain reacts to the are strongly depends on how many of our senses are still 8 it. studies on rats showed that when they were placed in simple the, our surroundings only 40 percent than euro pathways were active compared to real

life. the more realistic, the v, our experience, the more similar the brain activity became. in an experiment where rats were put on v r treadmills. their brain activity closely resembled brain patterns they have when they run on treadmills in real life. this shows that the more immersive be experienced, 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 trying to process v all similarly to how it would really experiences my the, from the shits he most of you and get him out of the brain. patterns are actually quite similar, but he saw a feeling of anxiety. his process pretty much the same in a virtual and i did 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 our 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 in can 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 averse thanks to the latest v . r headset, which track users i'm with the headsets use harmless, infrared light to ascertain where users looking. the addition means of

avatars can make eye contact. plus, operating menus are aiming at objects can now be done with i move in saloon in v r e i tracking tech should also help speed up your gain graphics. i will be knows that human either this is the age of your vision is a low resolution. so you can approximate a computing policy, dr. brenda, the actual well you can just render where the user is locking in rendering right now e, i can't reliably predict where use next. 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 traits can be gleaned from i data was more, they want, the data can be used to predict our emotional state dry 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 you know, much of the research happens in weston educated industrialized reach other countries. i'm not for that sort of bias for when you're trying to develop a technology based medication for humanity. yet last 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 start a campaigns even once expensive the, our treadmills on now somewhat affordable. these b r shoes are called actors one. they're still just the prototype,

but they're the only shoes you can do. the metaphors well, almost moon walking in real life. the shoes server motors go in the opposite direction to keep them from crashing to a real wall. the so called cyber, she pick a different approve the help of the crowd funding. for just a few 100 years more, you can get the swivel chair to play with the food comfortable. i'll be unexpected . with that in the midst of a few years of your 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 practice 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 v r fool body tracker is much cheaper option is probably the best value for money, but users should know it doesn't stop you. so you may want to be weary of wealth. 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 via device or one you'd like to see develop? do you think other dangers are bigger or do you not care about v r and preferred to focus on real life as no one youtube or by email? by and see you soon. ah

ah. i want to talk to you about inequality. the 77 percent. my connie, it is kimani and had crew talk to the people who feel behind the street debate from lagos. nigeria is enormous to resources in africa. the problem is that if you had got 15 on the combo width of the marci lang, nothing changing with the 77 percent of next on d w. wes, making the headlines and what's behind them. dw news africa. they show that the issue is shaping the continent. life is slowly getting back to normally where on the street to give you enough reports and the insights our correspondence is on the

ground reporting from across the continent. all the trends doesn't matter to you. in 60 minutes on dw, ah, rearing to read, ah, everyone who loves books has to go insane. ah, the dw literature list, 100 german must reads it's time again for your favorite use. sure to 77 percent on this program, we talk about all the things that are important to young africans. then a miss or t, michael or t. and on to this program, i want to talk to you about inequality. it is estimated that africa 3 retest below near men, half more wealth.
