accessible for the visually challenged
Agenda
About the Project
5 Areas of Study
Way Ahead
Who all should study math & science?
Mathematical and Scientific aptitude is sight independent.
Ground Reality
The gap between the need and reality
Two Kinds of People
1. Who believe it is not completely possible to teach/learn Math & Science concepts to the blind and low vision.
2. Who believe that the blind do not need these concepts.
Research conducted by Xavier’s Resource Centre for the Visually Challenged (XRCVC) as part of the Vision for India (VFI) Project
of the Tech Mahindra Foundation.

The Way Ahead
A person who is severely impaired
never knows his hidden sources of
strength until he is treated like a
normal human being and
encouraged to shape his own life .
