Wouldn't it be nice if they just told us so we didn't have to speculate? This is cool stuff and I'm glad I know about it but, as someone interested in this field of study, I'd love to try this out. But I guess I should stop being surprised when even a company like IEEE can't be bothered to write an article with any actual information. Just a bunch of simplified summarized crap.

At the bottom of the article is a link to the paper, which is open access.
