Students of science frequently deal with detailed information expressed in charts, graphs and diagrams.

For Indian national Kartik Sawhney, who has been blind since birth, the visual demands of his science studies presented a significant challenge.

On International Day of Persons with Disabilities marked annually on 3rd December, Alex Goldmark asked Mr Sawhney to describe the technology he developed.
