An 18-year-old who just finished high school has developed a revolutionary device(装置) which allows visually impaired or blind people to be more mobile — after coming up with the idea when he was 12.

“To be considered is a real honor. It means the work we’re doing is really valuable,”Alex Deans said.

The teen,from Ontario in Canada,began creating the tool after becoming curious while helping a visually impaired lady cross the street one day.

“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,^w he toki GOOD magazine,after seeing she only had a stick and guide dog — two things that are hard to come by.

The device,known as iAid,uses GPS (Global Positioning System) and ultrasonic(超声波的) technology to help visually impaired people get around safely.

The belt-like tool comes with a control handle and works by using sound waves to discover objects in the users’ path and show how close things are to them. The iAid works much like a bat uses sonar(声呐) .

The teen's invention has been attracting attention and it won the 2015 Weston Youth Innovation Award in May for which Alex was awarded $2,000 at a ceremony at the Ontario Science Centre last month.

“The entire group of judges was impressed by Alex^，s creativity,motivation and dedication (奉献) to building his design over a four-year period. We look forward to seeing future inventions from this outstanding young inventor,said Hooley McLaughlin,chief science officer at the Ontario Science Centre.

Alex is now working closely with the team at the science centre to hold an exhibition for his invention. He was also given the opportunity to give a presentation at We Day 一 stadium-sized events where speakers lecture about global issues across the US,Canada,and the UK.

Alex will be starting at Montreal's McGill University in the autumn,but hopes the iAid will be approved for US and Canadian rights so that,one day,the device will be available for those who really need it across the world.
