18-Year-Old Creates Device to Help the Blind Become More Mobile

He started at age 12.

For six years, 18-year-old Alex Deans has been working hard on the iAid, his invention to help the visually impaired navigate the world around them. According to Deans, the idea came at the age of 12 when he was helping a blind woman cross the street. “She told me that all existing devices only let users see in one direction so they can’t know what’s going on around them.”


The iAid blends GPS and ultrasonic technology to help visually-impaired people safely walk to wherever they like. It works by emitting sound waves that bounce off objects in the user’s environment to show how close the objects are to them. It’s the combination of a whale’s sonar and the technology used in cars to alert drivers when they’re about to back into something. According to Deans, “Guide canes tell you what’s in front of you, but they don’t help you figure out where you are in relation to your destination.” The iAid includes a joystick that rotates and points the user in the direction of their destination.

It took three years for Deans to create his first prototype and once it was ready he brought it to the Canadian National Institute for the Blind. At the institute, visually-impaired people got to try the device and after hearing their feedback, Deans would then create an updated version of the device. “When I saw the reaction from people using the device,” Deans said, “it motivated me to continue doing it.”

Within the next two months, Deans should be approved for his U.S. and Canadian patents for the iAid making it one step closer to being available to people everywhere. Deans hopes the device will sell for between $50-70 if he can lower the costs of materials.

Here’s Alex Dean’s submission for the 2014 Google Science Fair.

The global climate change strikes on Friday are said to have been the largest protest for climate change in history. An estimated four million people participated in 2,500 events across 163 countries on all seven continents. That included an estimated 300,000 Australians, but a total of zero were in Hyde Park in Sydney, despite a viral photo that claims otherwise.

Australian Youth Coal Coalition, a pro-coal Facebook page, posted a photo showing trash strewn across a park after what appears to have been a large event. "Look at the mess today's climate protesters left behind in beautiful Hyde Park," the photo was captioned. "So much plastic. So much landfill. So sad." The only problem is, the photo wasn't taken after a climate change protest. It wasn't even taken in Australia.

Last Friday, millions of people in 150 countries across the globe took to the streets to urge world leaders to enact dramatic solutions to combat climate change.

The Climate Strike was inspired, in part, by Greta Thunberg, a 16-year-old girl from Sweden who has captured worldwide attention for her tireless work to hold lawmakers responsible for the climate crisis.

The strike gave people across the planet the opportunity to make their voices heard before the U.N. General Assembly Climate Summit in New York City on Monday.

As world leaders meet to discuss new ways to tackle climate change at the U.N. Climate Action Summit, they might miss one very big part of healing nature – nature. In a new short film, youth climate change activist Greta Thunberg and George Monbiot, a writer for the Guardian, talked about how we need to use nature as a solution to climate change.

There's a huge push to curb emissions, but it's not the be all end all of handling climate change; we also need to remove CO2 from the atmosphere. While we don't have technology to do that for us, there is another solution. "There is a magic machine that sucks carbon out of the air, costs very little, and builds itself. It's called a tree," Monboit says in the film. Researchers found that we could get rid of two-thirds of the carbon dioxide that we've emitted during the industrial era just by growing trees. That amounts to 205 billion tons of carbon. Right now, deforestation of tropical forests is responsible for 20% of current greenhouse emissions.

In 2016, 196 countries signed the Paris Agreement, pledging to combat climate change by taking action to curb the increase in global temperatures. The Paris Agreement requires countries to report on their emissions and what steps they're taking to implement those plans. Now that the countries are coming together again for the U.N. Climate Action Summit in New York City, it's worth taking a look at what kind of progress they've made.

The Climate Action Trackerkeeps tabs on what each country is doing to limit warming, and if they're meeting their self-set goals. Countries are graded based on whether or not their actions would help limit warming to 1.5 degrees C.

According to a recent article from National Geographic, The Gambia, Morocco, and India are at the head of the class. "Even though carbon emissions in The Gambia, Morocco, and India are expected to rise, they'll fall short of exceeding the 1.5-degree Celsius limit," the article reads. Saudi Arabia, Russia and the United States, on the other hand, get a big fat F. "Projected emissions in Saudi Arabia, Russia, and the United States are far greater than what it would take to limit warming to 1.5 degrees Celsius."

Greta Thunberg has been dubbed the "Joan of Arc of climate change" for good reason. The 16-year-old activist embodies the courage and conviction of the unlikely underdog heroine, as well as the seemingly innate ability to lead a movement.

Thunberg has dedicated her young life to waking up the world to the climate crisis we face and cutting the crap that gets in the way of fixing it. Her speeches are a unique blend of calm rationality and no-holds-barred bluntness. She speaks truth to power, dispassionately and unflinchingly, and it is glorious.
