Teen wins Ontario Science Centre award for iAid device

What was I doing when I was 12?  Certainly nothing nearly as useful as this. 

When he was 12, Deans helped a visually impaired woman cross a busy downtown street. While they walked, they talked. Deans asked what type of technology was available to assist the blind. There wasn’t much, he was told.

So, he went to work as soon as he got home.

The iAid works much like a bat uses sonar. The iAid uses four ultrasonic sensors mounted on a belt to scan and map a person’s surroundings.
