in hand, but also of his ability to protect purchasing power, run galaxy. in fact, he before the shop, while net crohn's margin of victory look set to be narrow. he does remain the favorite to win and become the 1st french president to hold on to power in 20 years . why should you have the news? that's it for now, our tech show shift is up next state in for that. and we'll see us in the double use crime fighters are back with africa. most successful radio drama series continues them all episodes are available online. and of course you can share and discuss on d. w, africa's facebook page and other social media platforms, crime fighters, tune in now, how long does it last, ah, or an eternity?

time it can be measured precisely. and yet each person experiences it differently as if there are different forms of time. time a phenomenon, a dimension and illusion. about time starts april 14 on d, w. 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 ads as you can virtually flow through space or kill monsters. but at virtual reality is about to take immersion to the next level.

developers, i in a raised to make it even more realistic by incorporating more of our senses like touch. the new buzzword is happy. we are picking something up with your hands, running your fingers over most or reaching out in shaking hands with someone else in the matter of us. that will 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 these 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 or august to interactions and that that is the key thing for the our to the university of chicago is even looking into so called chemical hap,

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 are set to be homeless and small doses of full body have to keep that 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 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 agree yeah,

optics and b r one full body should, is the task lawsuit which provides tactile feedback through electrical stimulation . it can even recreate the feeling of rain on skin or temperatures, arranging from $20.00 to $40.00 degrees sal. yes, that's pretty incredible. but the sued 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 gains 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. 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 with mountain the matterhorn or bungee jump of a new york statue of liberty. and there are certain sort of experiences that you can get you in a virtual world or would i be possible and any otherwise. and those that's where i think this is an entertainment service. betty b r is a real sort of game changer getting last 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 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 lifestyle. so for example, senior meeting raster social cases that perhaps a surgeon my only eval operator unless, if you're able to simulate 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 learn 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, all surroundings only 40 percent of than euro pathways were active compared to real life. the more realistic, the, the, our 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. 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 ana between 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 meadows new mixed reality had said include spilled 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 v r headset, which track users i'm with the headsets use harmless, infrared light, 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 eye movement saloon via

the 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 the 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 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 cold, actually one. they're still just uprooted. 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 put the food comfortable. i'll be unexpected with that in the metaphor. serious v. r gamers and the 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 $1200.00 youth. 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. your 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, the, our safety isn't really safe yet, but what do you think? do you have a favorite via devise 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, the

enter the conflicts own with sarah kelly. the ones has been confronted with horrific images of atrocities against the allegedly committed by russian forces in ukraine. we can find a car and then paul, good genocide, how should western allies respond? my guess i'm comb with foreign minister gabriella lunch bag. he joins me on the line with the city for all aspects of life. climate change is not just about computers. it's more than the draughts and floods in the himalayas feel in the youth. and when people are you, when he came back to by climate change because of intersecting one already the weight of the human cost of climate change in 30 minutes on d w. so you want to know what makes with

love on banding thing that way. but i'm not going to have to watch my own car and everyone with later holes and every day getting, are you ready to meet the german can join me. rachel stuart on d. w. the world has been confronted with horrific images of atrocities against civilians, allegedly committed by russian forces in ukraine. we can find the courage and then call it that genocide because there are so much resemblance off the events of 20th century. how should western allies respond? my guest on conflicts owners, lithuanian, foreign minister, gabriela lands burgess. he joins me on the line from building to newsome which is more than just one person.
