Accessibility Technology -- Research

Hello everyone, just a brief introduction: I'm an engineering student (who enjoys writing, no doubt) conducting research into disabilities and accessibility barriers associated with those disabilities. I'm literally at the beginning of my research, and thus I only have a very general conception of disabilities and current accessibility technologies. I'm looking to limit down my research to a specific area that could benefit from a technical solution to a barrier created by a disability (and it can be possibly any type of disability, whether physical or mental, or beyond). We will actually be looking for technical solutions and prototyping our concept. The goal is to pair up with a community group, or any local entity which would be interested in providing feedback for this endeavour.

So my question for the forum is: Do you, or anyone you know, face an accessibility barrier due to a disability which could benefit from a technical solution?

Thanks everyone!
