12-year-old who creates tools for the visually impaired
12-year-old Hari Bhimaraju from California, U.S., loves creating tools for the visually impaired.
Her first was a periodic table teaching tool called the The Elementor where she used her knowledge of chemistry to create a system that uses sound, voice and LED lights to teach people with low vision all about atoms.
Hari even showed her project to President Obama, which her family describes as an important moment.
Hari has also created a system of medicine management for people who are unable to understand what is written on medicine bottles and packets.
She created an iPhone app that uses radio frequency identification to scan the labels that tells the user when the medicine will expire or need to be refilled.
