multimodal interaction use cases: disabilities included?

Hello:

Disability advocacy hat, (not a job title but a fair description of some of what I do) 
and as a blind person:

I did not see use cases with people with disabilities explicitly mentioned.
Are they implicitly covered?
Is it possible, for example to say something like
"Computer, change to no sight mode for input and output."?
All the cases seem to imply the user has all modes available, it's only the device or situation that temporarily excludes thhis or that mode of interaction.
Did I read this correctly?
 
Programmer hat:  A fascinating sketch of near future web technologies with many interesting problems to work on.

Thanks,

Steve
