Assistive Technology Video and Questions

My reaction to this video was wow. I think this was a very neat video about how to help children with disabilities to learn. I never knew about the different techniques they use  until I watched this video I  have never been in contact with an assistive technologies. I am looking forward to the guest speaker so I can learn more. I hope the guest speaker bring the techniques with them. The questions I would ask, is what made them come up with these techniques and do they really learn from them.
