Hi Emil, that's a great question. This particular technology has a lot of really great applications for people who are blind, or are differently abled.
In terms of using it for ease of use, I currently have a hard time with it. I'm freaked out about who can listen to me so tech like this gives me the real heebie-jeebies. But, I also prefer going to a real checkout person at the grocery store rather than the automated ones, so I might be the wrong person to ask. I think there's potential! And some potential that is pretty important.
All that said, I was skeptical of CSS when it came out. I just didn't understand the need for any styling of any kind. Soooo like, take what I say with a grain of salt.
