18 year old Alex Deans surprised the world by inventing ‘iAid’, a cloud-based companion device for the visually impaired to help them navigate around effortlessly.

iAid looks like a joystick and is equipped with ultrasound, GPS and cloud features which helps it create a virtual environment around it.
