corona virus infections on the decline in europe germany has begun easing border controls with neighboring countries was good news for europe's tourism industry which took a major victory to me. this is of course due to the news live from berlin that more headlines top the hour on this farce or just watch. the top. stories of people who've world over the information they provide. the means they want to express g. w. on facebook and twitter and up to date and in touch. follow us. and. how does a virus spread. why do we panic and when will all of this and i'm sure just through the topics that we cover and

a weekly radio show is called spectrum if you would like any information on the cross or any other science topic you should really check out our podcast you can get it wherever you get your podcasts you can also find us at dot com or inside science. ship special how researchers in germany are driving the future of mobility. driving cars are full of artificial intelligence and the technology keeps improving reporter oxon voc not visited researchers at the sci research center and lead and autonomy askari taken for a spin through the streets of cars school. this car is a model for future a i'm open to. talk camera and i want to officially intelligence guidance system help it stay in the correct. plain and recognize ready to mock

a position that you like in the cockpit in staring will attend. to accidents help you but this isn't a game it's fundamental research and development of a self driving ai cause at the college of research center if the information technology as we did i can see this model is ideal because we can test the ai in a closed and secure environment. that way we can spot problems early on without the effort of having to use an actual vehicle in some ways and a quick attempt to grab the wheel. is the better driver. by having the dream. ai can even recognize the drive as condition today dashboard camera systems can already detect whether the driver is sleepy and in need of a break this ai system. or my heart rate i would exactly does that. see these green areas highlighted bear on your face.

because these areas are sections of our skin or ai can determine our pulse by registering the slightest changes in skin color. we humans can't detect any difference. but a camera can detect and visualize your post for us not. recognize and process the works of biometric data like whether you'll stop. feeling relaxed or about to fall asleep this recognition. so much cars nowadays are already using simpler systems that can analyze your blinking rate and recognise when a driver is getting tired in which case it will recommend the driver takes a break. in. exactly and in the future we might have autonomous cars that only take over in certain times like a traffic jam. once the traffic jam is over the car needs to be sure that the driver is ready to take back the steering wheel. future cars might even be smart

enough to drive according to your most. systems basis cocom a self driving gun at the edge said i research center in calls throughout. it's being used to explore automated parking reporter axel wagner uses his smart to them to summon its future cars could independently look for a parking space and even be called to the exit via smartphone when it stopped at the exact spot agreed upon the system works but to be safe to scientists stay on board and on case they need to know to be. ready to go with of course this is ok i would do one of them. the car does all the drive at the right yes ok. they're off for a ride around the testing compound wall as it does at least artificial intelligence to make here this. involves fun in self driving vehicles artificial intelligence is

used almost everywhere it's mainly used to detect the vehicle surroundings on the other or in other words the vehicle has to be able to tell which objects are around it and how these objects interact with one another. and how the vehicle should react to these objects ok take a traffic light for example become must be able to identify at this particular traffic light is built to send signals on its current status to the car additionally and onboard computer uses ai to transmit g.p.s. data of a spiritual man and thereby determine the route. but how well does other people on the road. you mean to say i was just passed you are very short so you're going to start exactly it's part of the cycle it's shortly and then continues cautiously waiting for the road to clear before it accelerates again. but what about

a careless pedestrian who steps onto the road without paying attention to traffic. will he be spotted to you. in the mean he's safe thanks to control sentences on the roadside which transmit the pedestrians exact location to the car. in the future smart cars will need wide reaching technical networks in traffic to ensure everyone seems safe. then says bertha one equipped with cameras and all kinds of senses it's one of the 1st cars in germany to be allowed to drive autonomous me outside of the testing compound this is where if you break your computer is and if you get a hot yes exactly this is the main computer along with quite a lot of other electronics it's as complicated as a looks or 2 that means artificial intelligence reasons we're here in this area going to the sensors are built in here at the back. starting off at the research

center but who will take the team for a run each through the streets of cars through our. traffic lights. and stop signs . and above all on coming traffic just a glimpse of what's to come in the city center. destination is the testing ground for autonomy driving. this is where bertha's behavior is monitored and recorded similar tamia slate she receives valuable information through cameras and sensors along the roads. this network helps bertha maneuver through traffic independently. from which there's really focus because you don't quite trust the right dog yes exactly. goddess of the status these are just tests and you need to stay focused. it's much less relaxing than driving yourself. but that will change once everything works more reliably we're still. so you know millions of signals are transmitted to

the onboard computer tech every 2nd it uses ai to analyze any information that might be relevant for participating in city traffic when we're driving up brain takes over this job with a hey i there's still room for improvement and for a brief moment bertha is overwhelmed. so you have to take over it's what exactly i had to intervene at this point on the road the car always has localization difficulties as there are many distinctive markings around mark peoples and so the computer struggles to locate where it's at and that's why i took over for a bit because he understood the courts i could hire for you know. just like when you think i could buy a car like bertha a car that can independently see the city provided i think ford of course does aside and it's hard to say you know because there are so many different situations to consider and if some experts say it will take another 10 to 15 years but i want

to count on that there are still too many unforeseeable situations in which a human would be able to respond but a car wouldn't if clark above it so it's still too difficult to estimate how long it'll take. so for now at least bertha remains one of a kind. you feel good about are you going to lick. somebody's eyes systems in autonomy as cars use what's known as optical flow to detect others in traffic scientists at the max planck institute in tubing and show how easily these systems can be hacked. these 3 scientists on turning around and testing the optical fly with an artificial intelligence the idea behind it for the ai translates movements like cans movements into cullen's but these are change according to the movements direction. is moving to the right. then then your

optical show is going to look like yellow in the color map and the foster the brighter the color is so so if it's moving right at a really high speed then you see it like a bright yellow thing and then if it's moving slowly then it's more towards the light so we have like a color wheel representation which sort of like shows the corresponding to the lawsuit is itself like happened in the video and objects. whenever i know recommend john moves to the left the computer displays things such as the color yellow bright purple. but there is much more to optic flow. the computer also calculates sometimes dissipates the movement of other objects in the vicinity. when the car continued driving straight away that still is a commission imminent i can calculate this in a fraction of a 2nd. to the computer every image is a fresh image a circuit seeing the world every. 30 times a 2nd brand new an optical flow is what connects things across time and allows the

computer to have a consistent representation of the world much more like we do. the scientists want to try to disrupt ai working with the optical flow method. to do this they've calculated colorful patterns. they might not mean much to the human eye but they certainly mean a lot to ai this one here shows ai off the most. that the motions. start. when the pattern is covered up the system works fine. but once the pattern is visible the system gets confused and can no longer compute the optic flow. to artificial intelligence this is a jumble of contradictory in from. we were surprised by the extent of the problem.

we weren't surprised that i could be disrupted like this. there was already pretty existing research on the issue patch but seeing how such a small patch can are such far reaching consequences is quite worrying. if they become a full passenger patch takes up just one percent of the area of the ai system reads it's going to still have up to 50 percent of its feel deficient. that a lot of people wanting websites which can work in the end of it's going to work and then like foggy climate and stuff but i think we can try and start from this like this with twists can be a lot worse for these you know. this patent was calculated that means hackers who understand artificial intelligence could create similar patterns if they do they could completely disrupt autonomous driving systems there may be a bit of

a war going on between people trying to attack and people trying to produce robust systems this is exactly what we see also with any kind of security software you know hackers find a loophole in some operating system they inform the manufacturer of the new defenses are made and then you know it's an evolving system that researches want to use what they've learned on how to hack into autonomous driving ai systems to warn manufacturers off the danger is if they can make autonomous vehicles more resistant it's not just tax then sure that want to make smart cars will be safer drivers but if you.

how do we reach see the screen or how can we protect habitat and so we can make a difference google only genius or environmental series again google $3000.00 on d. w. and online. we realize that we will never be able to go back to life pretty covert 19 we have to live with this risk privacy is a very important human rights but it is not an absolute right to have you sacrifice calls to improve human rights in order to keep the dialogue going well i think you keep saying concerts were not concerned south korea has been hailed as a model country in bringing its corona virus infection rate under control but the methods have raised privacy and public shaming concerns and now there are reports that the virus is back again my guest this week is south korea.
