Alex Deans has a lot to reflect on this summer. The eighteen-year-old Ontario, Canada native just graduated high school. He's also changing the way blind people everywhere will be able navigate the world around them. For the past six years, Deans has been working tirelessly on a device now known as the iAid, a navigation system that uses ultrasonic technology and GPS technology to help the visually impaired get where they need to go. The belt-like structure comes with a joy stick and operates using four ultrasonic sensors, which send out sound waves that ricochet off objects and alert the user as to how far away that object is. The idea first came to him at age 12, when he went to help a blind woman across the street. All that was at her disposal was a cane and the option of a guide dog, which is often hard to come by. Dean told Good News Network, Guide Canes tell you what's directly in front of you, but they don't help you figure out where you are in relation your destination and objects that are farther away." The iAid helps users steer around objects in their vicinity and includes a joystick that swivels in their hands, pointing them in the direction they need to go in. As far as pricing goes, he estimates the device will only cost about $50-$70 per unit, if he can get the cost of materials down. He hopes his invention will one day replace canes and give blind people the ability to maneuver more easily on their own.
