africa's most populous nation a blog just economy has a youth unemployment problem in a bid to control the internet of the future some sad kind of digital i am told so this folding we bring you the stories to the shaping the economic world we live in . counting the cost on al-jazeera. living life impossible to adopt this according to the world health organization approximately two hundred fifty three million people globally a vision in pads or a text line. today on tech night some of the latest innovations making it easier to help people the site problems navigate a complex well if you want to grab

a basket they're just slightly outward died. and even enjoy off again through a gentle touch i think there are so many people that i met that were really crucial to this and later as populations age and then patents become the prevalent a new study to determine what technology is needed in the future to ensure that people can live independently at home safe and happy we really need to figure out ways to better help people as they age as they develop various chronic conditions and do it in a way that optimizes their quality of life the scientific into the crystal ball of aging this is techno a show about innovations that can change lives we're going to explore the intersection of heart and humanity and we're doing it in a unique way this is a show about science by scientists.

new york city. an intersection is similar to many of the world city streets often a confusing maze of speeding vehicles to live moving masses of people who assume the time you see navigating side groups traffic lights cross works in construction sites i'm challenging for most people but the complexity of this intersection increases dramatically for those with limited visibility for those who have blind. techno stuck to crystal reports advocating a major metropolitan city is difficult no matter where you are but the visually impaired find it especially difficult now new technologies are being developed that can help even the playing. technology really really useful

at the same time it's not like technology is just doing everything for me you know it's helping need to do things myself twenty eight year old lindsay yes a lino of boston massachusetts visits new york city often blind since birth years of training enable her to navigate these busy streets i'm using a cane and it's essentially a glorified you know stick but it does its job very well and new technology yet doesn't need to replace things but it can certainly enhance what i'm able to do twenty third street and seventh avenue is a new york city department of transportation pilot intersection for new technology . in two thousand and eleven the city installed the first a.p.s. are accessible pedestrian signal here. today of the twelve thousand four hundred sixty intersections controlled by traffic lights in new york city two hundred nine now have a.p.'s and the number increases by seventy five each year. the beeping

boxes are helpful especially when you have an intersection that's a little more dicey it tells me that ok the light did just change so i can go i should go now as long as it sounds see if these devices while improving the safety aspect of crossing streets are currently in need of an innovative update re orks city discovered that after they had installed these devices that people people were still having difficulty crossing the street because of the increased complexity with the introduction of dedicated bike and bus lanes so they came up with the idea of actually adding a map to the sari in this intersection a printed tactile diagram is being tested at the excessive book the test room signal recently some new innovations in printing have made it possible to create very low cost talk trial graphics and braille songs that are durable enough to put

outside lindsey demonstrates the tactile math to passer by george this is also blind so if you feel the braille at the very top it says west when he first street so that's the doing that would be crossing this this line is showing the direction of travel these arrows you're a lanes of traffic so you have us believe you have fully waynes of traffic where the cars are going you know from your left to right there's a why here. oh oh you are here yeah right now you know what to expect in the past three days yes ok yeah steve landau says this is the first step in making traffic signals more interactive future generations of science he says will actually have a verbal function and it'll say car or bus or cross walk so by adding speech. and interactive aspects of this. richard really universally accessible i think the

most exciting potential is technology that takes into account the skills that a person already has and then fills in the gaps and also to do different kinds of things that maybe aren't as easy for me to do now. flex to lead agrees blind since age eight today at thirty three he's a u.s. paralympic athletic champion who currently holds the long jump world record. well his athletic abilities put him at the top of his sport some complex and even common tasks sighted people take for granted often challenge him we met lex at a supermarket in ocean beach california how difficult is it for you to navigate

with someone like you would take take for granted as a mundane task like grocery shopping i think is one of those things where a lot of times our stores will have a. customer service area so i would go so that that would require me to have a specific list of items there are those times where. you want to learn more about the product you want to learn what types of ingredients are in there maybe you want to make a better selection going our fleet so you know a lot of times on very particular about what goes into my body recently lexus sidestep the help desk for something decidedly more high tech today he shopping with ira i like thanks for calling i wrote this is a. the grocery store. interested in picking up a couple of things what are you looking for today you know are interested in getting. lettuce and tomatoes. and cucumbers for sour

already so it doesn't scare me your head around so i can take it. ok so the cash registers are to be where the produce days of your skin ready if you the produce market is to the right hand side of lax is not shopping alone he's connected in real time to an agent assistant who could be hundreds of miles away from him but is feeling exactly where he is. aron kader is the manager and agent operations what does it mean to be an ira agent it means that we get to assist the blind with their day to day tasks and give them more independence and freedom so as cited folks kind of take for granted just jumping in the car and running to the grocery store to pick up a simple item and getting back home now with the use of they can really incorporate that and just jump on public transportation or an hour and run to the grocery store with outside assistance to humans one bit in the book one person sitting in front

of a computer connected through technology and acting as an individual to do. to do an activity. you know experience something beautiful here's how the system works spark classes with a built in camera is paired with an app on the user's phone when they want to systems they press a button and via cellular service they're connected to an agent who is currently using this technology are called explorers and agencies the video in real time streaming in from the glasses that the explorer is wearing their g.p.s. location and a full profile on the user back in the supermarket lexus navigating the produce area there's a child with a car stocking the bananas he just oh i love those so if you wanted to step forward here. what car is going to be here on the right and then we're directly in front of the right ok so i see. pepper potatoes and i see what i believe are

cucumbers if you want to extend a hand you'll feel. let's see there will be potatoes on the top and then the second row down i will be cucumbers so i can't see your hand in the camera if you don't mind talk to your chin to your chest slightly so the video drops down yeah ok perfect you've got a cucumber in your hand to me teaching like how to tuck their chin to their chest which is not you know it's a kind of an awkward movement for someone who doesn't have vision is to. look down to the floor and look up to the ceiling so then you really build that report on the teamwork that's so interesting that those movements i would take for granted because that's how i explore my space wouldn't really be necessary yeah it's interesting because when you say look down like to them they're like well i am looking down but if you say stuck your chin to your chest that gives it more that more just that little bit more description really tells them exactly how far to look down. slightly down go down one row. and that's the caesar

supreme but your fingers. thank you so it's got to keep the boat crew directing. as well. are you still interested in a tomato. please ok let's take a peek around so typically tomatoes aren't refrigerated so if you want to turn do you have full turn around that's all i want to eat ok so you don't see any tomatoes here and on the other side we're so let's head towards the right side. and if your pa's here and turn your skin your head. that's on your left hand side so if you were to do a couple of steps they're actually the theory of this case here the tomatoes are on your right hand side so well now that you're out there on the left hand side. on this one here. if you want to extend your hand now directly in front of their

apples or tomatoes. over. this feels like a tomato and if you'll just tuck your chin slightly. is a tomato so it's a red. i don't see any. holes in it while grocery shopping is just one small task in lex's life he uses this technology more complex situations like travelling through airports or visiting major cities for the first time so for me there are those. where you want to have that specific information you want as many details as possible and so you know for example i went to vegas was like you know what i want to go out on the streets of vegas. and caught up. you know they were able to navigate me around and walking around on the street it was really is an amazing amazing experience because i just felt really empowered and i hadn't done anything like that before we do have you know low

thousands of people who are using this obvious explosives we want to get pretty much into the hands of you know every line in the world a grand task since there is a cost to using this technology the subscription radius from eighty nine dollars some. three hundred twenty nine dollars now on the higher end the twenty nine dollars it's unlimited use of service at the glasses for free data is free they don't pay for the data in funny usage and we also include insurance associated with the glasses. because they are stevie's that purple flowers and three thousand flowers a year and a couple of bright. roses i'm not sure of the right order. all righty so if you want to move to the check out why. around this power. forward a few steps of the turn to the left. find

every. where exploring the news for a new environments new things that i. haven't seen in the sun so. exploration processes it's amazing. we have that technology available to us this is a boon for point we're right now in technology there is so much going to help people. it's phenomenal it's way better than i was when i was younger meat lover dennis perot since becoming blind later in life he gave up visiting museums until today a new scientist famously proposed that there were nine ways that our brains help us

to appreciate visual art but how do you appreciate a painting that you can't see the answer might be here at the san diego museum of art they're taking an innovative approach to making art accessible to the visually impaired dennis is here to experience a masterpiece specially designed for the visually impaired. museum associate curator michael brown describes the original we're standing in front of one sanchez cotyledons masterpiece the still life with quince cabbage cucumber and melon it was painted in sixteen o two into wedo in spain and it is a groundbreaking example of still life painting at the very earliest decorated of the of the seventeenth so what makes it so special this painting was a really pioneering depiction of a three dimensional illusion so he's using in two dimensions he is creating an imaginary tactile experience do you think it's possible to you. to give that same

impression to someone that's not able to visually see this painting absolutely because i think that that one of the one of the ways that we interact best with with the public and of all different abilities is telling stories and the stories help to bring works of art to wife and although we can't touch this painting itself we can touch the replica and filled with those stories understand it in two thousand and fourteen we had this made so that people who can see this painting can still experience it so tell me how this rock because different from the real thing so first of all you can touch it right and when you look at the real thing you're going to want to touch it which is exactly what dennis perowne did for the first time today. this. patient. find this time. notice that the slope

of the lower right side. pages wanted to show that. perfect. i don't think you feel bad for fracture central but now you rest on the winter's. you to paint the rough exterior skin of the bow and wraps around. some of the roof several slices and one of the slices can be found sitting on the windowsill read it to the right very. front page has been sliced from the ground slapped noticed the rough texture of the rock salt right away drifting to the out so. well i went past it just the repetition helped drink something strikes issue yes it does but they still this was. the severest variants are you know there's a rough thing here and i don't know what that's represented in your transform i

think i think what you're touching is the it's rust in this model but in real life it would be very soft and that sort of pulpy cannot mean anything with e.c. ok that's what i'm hearing and that's where i'm hearing that difficulty the second time you explored the painting you are starting to add sort of layers to the experience after you've gone through the entire thing once do you think that the same is true for tactile models of paintings in general would be more experienced as hell that's a good question there could be there's a first time i've done anything like this and i was crying trying to block out the you know the narration so that i was actually experience for myself it actually did get better that's for sure but how important is it for these efforts to be made for art galleries to be creating things like this for people like you i think it's crucial i think there are so many people that i've met that would really appreciate this these are just a few of the accessibility technologies currently in use and as our populations age

more innovation is needed to meet the demands of people who become impaired as they get older we pick up that part of the story in portland oregon. a major study called current collaborative aging research using technology from the national institutes of health is currently underway to assess accessibility strategies for senior citizens so they can extend their ability to live independently as part of the study over two hundred senior citizen households across the united states are wired with activity trackers will start at the home of beverly healing ok beverly so we're we're in your home as you're wired up here with a lot of sensors tell me what we have well as we come in the door and there's a sensor on the door which simply means the door's been open and it's assumed that somebody is coming and going eighty two year old beverly healey is a volunteer test subject in a study looking at what happens in the home as we age and what excess ability

strategies can be created in the future to remain independent for longer her home has over twenty sensors monitoring her every move dr jeffrey k. of oregon health and science university is the principal investigator of the study if you ask people what they want to have happen to them as they get older ninety percent ninety nine percent will say i want to stay in my home or where i want to be as i get older on the other hand of course people say that because they fear going to a nursing home if you're developing alzheimer's disease which is actually now the most feared. condition in america wow so we really need to figure out ways to better help people as they age as they develop various chronic conditions fill in the ceiling going down the hall you'll see a series of motion detectors that say how fast i'm walking this is my usual gait

and if that should show slow appreciably they would notice that and they'd say something's wrong earlies not moving as fast as she usually does and she's lost her energy what's happening we are integrating multiple types of data that comes in twenty four seven. that reflects real day to day function across the the main things that make a difference in people's lives so what we're able to measure or monitor with the technologies are things like mobility sleep cognitive function so in here is my pill box which is monitored by the modem on my computer and when i open it up in the morning or in the evening to take my fellows that registers on the computer so you've got pills for every day of the week here yes and it's just getting a sense of whether or not you open the yes not necessarily if you took it i guess but no there's no way they could know that but they can know that i've come to the

pill box i built it up and honest and we have taken the pills out and one of them thomas reilly is an information technology systems architect at oregon health and science university i develop the software in our car servers collects the data from the sensors and brings it back and stores it now can you show me some of the information that you're getting sort of so right here we have display from our database so this is the sensor identifier and this is the timestamp here you can see she's not present in that room so the thirty says not present thirty says not present an answer a here at this time stamp she becomes present in the room was chosen for ten seconds and then comes back and a couple three seconds later it's present ten seconds so this is just one sensor in medicine changes everything and most change we detect is by itself report you go to a doctor's office and what is the doctor do they ask you a series of questions do you take your medications are you exercising how are you sleeping and we all do our best to try to understand that but it's very hard and we

know from our own studies that people actually are rather inaccurate in fact in how they are able to report with the data that we get we're able to get the actual data and then you can imagine going forward that if you were to come. to a doctor's office imagine that instead of asking you all these questions not only just were known but it's the real information is the actual events that are happening and then the appointment would be spent more in providing care and counseling as opposed to questioning where do you see some of the innovations what's on the horizon in terms of accessibility for the elderly and senior citizens there will be a natural shift to more comfort in just having technology around and using it voice recognition continues to to advance quite rapidly so the interface for how you

conduct. interviews how how you interact with technology in general is very rapidly changing the data they're collecting is helpful as it's grouped with data they're collecting from other people just like me who are also contributing to the program and that somewhere years from now or months from now the data that they're collecting and assimilating will create a pattern of aging for people who are twenty years younger than i am and feel happy about it that's it for now i'm dr mara see you next time on techno.

a nation where corruption is endemic embroiled in a battle to hold the powerful to account. how does this radical transformation occur. i mean if you know about it i mean if you really want to shedding light on the romanians pressing for change and the unconventional methods to eliminate corruption remain people on al-jazeera. where. you are not. exposed prominent figures of the twentieth century and how life already has influenced the course of history was the cuban revolution communist the way feel castro is a feudal east the not a coming east that custer wanted his country che wanted international revolution

became a point when the relationship came to an end the icons of revolution who changed the course of latin american politics. and fidel castro face to face on al-jazeera . called the must move hussein has now been held in pretrial detention for two years what is his crime. why hasn't he been tried yet why hasn't justice been applied in this case is he detained because he's a journalist as journalism become a crime have moles become a tool to silence wars of truth we will continue our news coverage with professionalism and impartiality our work will remain credible and accurate but journalism is not a crime incarcerating journalists is not acceptable we demand the immediate release of all colleague mahmoud to say and all journalists attained it gyptian jails. and

all his colleagues we stand for press freedom. hello i'm maryam namazie and on the just a quick look at the top stories now tens of thousands of algerians have been protesting in the capital and around the country calling for president abdul aziz bush if he could to step down this despite riot police being deployed in metro services halted by the government in an effort to stem the protests demonstrations first began when the eighty two year old president announced that he would seek a fifth time in power meanwhile a private algerian t.v. station is reporting that nine politicians from the ruling party have resigned and joined the protest how much i'm jim has will.
