Smartphones are used every day for multiple uses, but have we ever wondered how we could use them to introduce some light into the world of the blind? Ji Dong, an inspiring youth did. Together with his visually impaired business partner, and through the help of Microsoft, he translated his ideas into reality, coming up with a cell phone that enables the blind to carry out common activities like calling, texting and navigating. 

Look out for other amazing youth from the Microsoft YouthSpark programmes.
