As a Deafblind person I have to have "unique adaptations" in assistive technology. If you look around on some assistive technology store sites, you'll see there's a very small amount of equipment catered specifically to "Deafblindness", but a lot for "Blindness" only, or "Deafness" only.
Why is that? Because Deafblindness is so varied in their abilities! Many people automatically think "Helen Keller" when they hear "Deaf and Blind", absolutely no hearing and no vision at all. Well that's far from the truth! Did you know that 9 out of 10 "blind" people actually do have some usable vision? Whether its a very small area (such as tunnel vision), detect colors and shapes only, or light and dark only. On the other side, Deafness doesn't always mean completely void of sound. Some can hear sounds but no understanding of speech (like me and my Cochlear Implant), some can hear low sounds only, some can hear speech with strong amplified hearing aids.
So the reality is, we have to make unique adaptations and "pick and choose" our equipment. The Deafblind person with some usable hearing could choose to use an amplification system. Others with usable vision could opt for Large Print items and CCTVs. Still in the end, some people with true Deafblindness are "left behind" in technology options and availability.
I shall clarify what I mean in future posts, but for now think about unique adapations in your life...
