thank you for your solidarity on behalf of my community, my. com, since the march ended at the brandenburg gate with enthusiasm still hiv and the celebrations are set to continue into a warm bowlin night for i. this is debbie news live from berlin up next shift looks at wearable technology that lets you control machines with your mind. don't forget, you can see all the latest news from our website d, w dot com. i am told me all the logic. well, thanks for watching india, a lead of contrast of ambitions of inequality. 75 years ago, mahatma gandhi peacefully led the country to independence,

full of ideals. what is remained of his vision with what's the status of human rights and social justice in what's called the world's largest democracy? we receive your head it. this is the pulpit tour unleash on violet bass and re imagine dolly's teachings for relevance to gandhi's legacy starts august 6th on b. w. imagine you could control computers using only your mind. he could play a computer game without touching the controller. thanks. does system that translates your brain waves? well, we all sunday have chips implanted in our hats. oh, where special caps that read or thoughts bring computer interfaces?

our topic today on ship ah, b c, eyes or brain computer interfaces are systems that link our brains directly to computers . tech entrepreneur, ellen musk, for example, wants to merge the human mind with a eye for which we would have to have a chip implanted into our brain. that's pretty invasive. but there are also none invasive brain reading tech. one type measures electrical activity on the scope. in medicine, they use e. g caps for this, but sleek are looking wearables are available to. you only have to think and the lamp stems the light and the video begins to play all thanks to this. wearable the head band is a non invasive brain computer interface, or bc i. it was developed by a neurotechnology stud up from france, senses in the headband, read brain waves, and translate them into commands for electronic devices. b, c,

i is like this could be game changes for video games. they could enhance or even replace controllers allowing full greatest speed and more intuitive game play. being able to control devices with thought is especially useful for situations when you need your hands for other purposes. a kid like this costs around $400.00 us dollars. these headphones from a u. s. stop claim they can tell their wearer when they focus best to help them work more efficiently. the electrodes which measure the brain waves are located in the headphone padding. electric activity in the brain indicates concentration levels. the measure data is processed in an app to show where is when they are able to work most productively music to fit your current mood and alerts for when you need a break are also included this b. c,

i should become available for purchase in 2022. for some a brain computer interface would be nice to have. but for others it would drastically improve their quality of life. like for people who are paralyzed, a successful brain implant would increase their independence. this stream has country for nathan copeland. here we see him playing the game final fantasy just by thinking. and here is his robot, hand and action. this is how his brain computer interface works. when nathan copeland suffered an accident in 2004, he was left with tetra politic paralysis. but thanks to a brain computer interface, nathan can now move a prosthetic arm. electrodes in his brain, read his brain waves and sent signals to move the prosthesis. the reason why we are able to control electronic devices by the power of thought alone is because our

brains use electronic signals. ah. the human brain has $86000000000.00 neurons, and each one sends signals across thousands of synopses. when we want to raise our arm, say, a region in our brain becomes active as neurons fire. if the voltage changes by a large enough amount, over a short interval, a neuron generates an all or nothing electrochemical pulse called an action potential, and a signal gets sent between the neurons. this action potential can be measured with electrodes. these have miniature metal needles that record the voltage change. the more needles in electrode has the more accurate the measurement. nathan copeland had an operation to insert force such electrodes into his brain to where implanted into his motor cortex, which controls movement and to into his amount of sensory cortex we're sensory

perception is processed thanks to these electrodes. nathan copeland can now control movements when he's connected to a computer. to achieve this, however, both sides had to 1st learn to understand each other. the computer needed to learn to read nathan's brain waves and translate these into the correct movement. to achieve this, nathan watched videos of movements he wanted to make. meanwhile, the b. c, i measured the action potentials in his motor cortex arm while nathan copeland was concentrating on the movement. the computer recorded the action potentials and compared them using artificial intelligence and machine learning algorithms. now, when nathan thinks the specific movement, the computer recognizes it and moves the prosthesis accordingly. through the 2 other chips in his summative sensory cortex. he is also able to feel with his prosthesis i brain computer interface. research has come a long way. take the example of neuro grains. these microchips are each about the

size of a grain of salt and have been designed to be scattered across the brain surface or inside its tissue. their advantage is that they can detect and pass on signals from many areas of the brain. a team at brown university in the us develop the system and there are many other projects the astray, liam companies. syncron has succeeded in getting a brain computer interface into the brain through blood vessels. thus avoiding the need for brain surgery, the 1st person to be implanted with his stent rod interface is the australian graham fell state, who suffers from a l. s and nervous system disease, which progressively paralyzes the body. his brain signals are transmitted to a sensor in the chest way we receive a forward them to a computer. this enables graeme fell state to chat and surf the internet using thought alone. here as subject imagines writing letters by hand

and brain computer interface transforms them into time to letters on the monitor. the accuracy is 94 percent. it is considerably faster than previous systems where subjects would have to mentally choose letters on a keyboard. these brain computer interfaces were developed by stanford university in the u. s. ah, previously, robotic alarms weren't able to have such fluid and natural movements. this new non invasive brain computer interface was developed by researchers at the courts university. as the technology improves, e g caps could become a future alternative to implanted chips. ah, using e g caps instead of brain surgery is definitely less risky. because implanting electrodes directly into the brain can cause bleeding or scarring, or the electrodes could be rejected. and if they need to be taken out at a later point, that could also lead to complications. but beyond the physical risk of brain

computer interfaces, experts worry there are other serious dangers. what would it mean if we were in full control of our minds? all same is addiction, depression, those could all become a thing of the past. but so could traits that make us human, which anxiety osman, great, i would say or traits can be altered by deep brain stimulation. and on come as a brush, for example, or someone who was shy, can suddenly become extroverted at yet spend more money target or change their sexual behavior. but i found that sense ex wife a hi, this is already been observed soon, but we'll back that. and it leads to the question of how important these traits are, eng shaft and how much they belong to something like our core selves can. for if something is an essential part of us in elisha's vasquez,

then we probably want to protect it. this one will remain in the ship and survive, and one person who believes in technology's potential is a lawn musk. everything that's encoded in memory you could, you could upload. you could basically store your memories as a backup and restore the memories you could potentially download them into a new body or into a robot buddy. the future is going to be where many new relatives do not buy into ilan masks. vision of brain backups can figure, hulu, saving the contents of the entire brain on a hard disk would mean covering both sides of the brain. so the entire brain with electrode and also copying the interactions between the billions of neurons accurately. i think that technically and physically this is not possible to see college. and then there are also ethical questions to consider

the longest i would be vulnerable to anyone who has access to this data that's from my bank details to my deepest secrets. the idea that big tech could know my private thoughts is really scary to me, but to be clear, there is currently no brain computer interface that can decode or thoughts. that mixture of images, sounds, smells, and words is hard to crack. we may soon have busy eyes that allow us to message up to 5 times faster by thinking the letters rather than typing them. yet there are important ethical dimensions to tech companies developing the systems like google, which is also investing in b c, ies, these companies have not always protected their users. and what if, at some point where pressure to linking our minds to computers, like where pressure to being on social media? what if any rich and privileged people get access to this technology? or if powerful figures like in on musk increase social pressure to join this trend,

those without bc eyes would be left behind density mass. now am i give insights from clang house on once these measures become available outside of the clinical context and then pressure to use them will probably increase off on that. o. s it us mahunis can man and um, but i, we've seen this in other areas such as beauty or sport where people feel pressured to reach certain standards because that's this then miss. and the other myth ma hm . this technology also lends itself to other uses like military purposes. the helmets shown in this film have electromagnets as used in e g. these are supposed to be able to control the brains of soldiers in the future in order to influence their anxiety or their aggression. what about pain? can you stop me feeling it? us army laboratories have been intensively researching such applications since 2010

of us doing also this is really happening. so it's not a secret. it's public knowledge on and our u. s. colleagues have access to a giant research budget and it was all that leaves me with a bad feeling of one good knew through experts believe that brain computer interfaces could provide a technical advantage and future wars by facilitating quicker decision making, better oversight and longer endurance. but how ethical would it be to manipulate people in this way and what, what the long term consequences b? if technology can help people were paralyzed, regain independence, then that's wonderful. that i worry about companies having access to my brain ways . our thoughts and feelings are the most intimate data we half. so data protection is more important in this area than anywhere else. what's your take on brain computer interfaces? what do you like to be able to message or play games using only your mind? let us know we'd love to hear from you. bye bye and see you soon.

ah ah, enter the conflict zone with tim sebastian forest johnson counting his final days of british prime minister in his grace, but still in offered my guest this week in london is sir malcolm rick, give himself refresh the fun following secretary. so what happens now to the former ministers of officials who indulge johnson? there is a little po, food who tore parted clean the most common place next on d. w. good morning speaking. how can miss passionate hatred of a people be explained gold hon. go. the history of anti semitism, our in depth documentary series, the final part after the holocaust,

the hatred of jewish people took on new forms and still pervasive today to say so then to semitism. in 30 minutes on d w. we've got some hot tips for your bucket list. magic corner check hot spot for food check and some great cultural memorials to boot w travel off. we go forest johnson, the counting his final days as british prime minister in disgrace, but still in office till his replacement was chosen. why did the conservative party acceptable, the lying and the youth turns for so long? my guest this week in london is malcolm rescue veteran conservative politician who .
