Reader
Key Findings (Vision Australia, 2007)
The more formats of material they can
access, the higher their employment
opportunities
There is a higher need for technical skills
amongst people who are blind or vision
impaired
What Technical Skill?
I still think it's worthwhile for a
blind person to try a career as a
programmer

Vancouver, Washington
Technical Skill would be…
Help blind and
vision impaired
people become
programmers
