[Ncabs] Student Seminar Potential Guest

Thu Dec 30 00:46:35 UTC 2010

Thanks!  I was kind of thinking about a combination of what you two were saying.  I think he'd be a good speaker for the fact that he's in a high-powered STEM career to inspire students to realize that they can do it, and I also think that it's important that we keep it close to our audience.  We don't want it to be too technical.  I think having him tell them the impact that his new refreshable Braille display can have would be great.  My understanding is that it will be a lot easier for everyone to obtain one because they'll be less expensive.  That's one thing that the blind community needs.  Special new features will be interesting.

I still want to hear ideas, though, so keep 'em coming, everybody!

I remember someone speaking briefly about this during breakout session
last year. I would be interested to hear what he has to say, but we
also have to consider our audience. If he could talk about the braille
display, and how it would relate to students in the classroom, I
believe that would better relate to the seminar at large. How would it
benifit students? What would be the difference between this braille
display and the current models as far as how assignments are
completed? That sort of thing.
If we could have him speak, it would be wonderful!
