Assistive Technology for people with Vision Impairment

I primarily chose this video because in the school where I teach we have the benefit of having a Smartboard in each and every class. I was intrigued to find out how they could be utilized to teach someone who has a visual impairment. The idea of having the lesson being demonstrated on the  Smartboard also being shown on a computer monitor for a student was brilliant. While text can be enlarged for a student relatively easily, it is the "in the moment" instruction that a student who is visually impaired may often miss out on. I wonder however, if in our integrated schools some students may be reluctant to use such a system because it may draw increased attention to their disability? I would hope that in this age of integrated technology use, the stigma of using such a system would be minimal.
