This is from 2012. I tried searching on EyeSee Mannequin and I found a bunch of news articles also from 2012, but nothing much since. I did find one article in 2015 about how they were incorporating speech recognition to determine if nearby customers are talking about what is on the mannequin.

So, either the tech was so expensive and unreliable that the company Almax went under and nobody else bothered going down this path, OR it was wildly successful and the tech has "gone dark" somehow. Though the real answer is probably somewhere between store owners found a cheaper way to do this by upgrading existing camera equipment, or because "malls are dying" nobody gave a crap anymore.

FWIW, back in the early 2010's there was a lot of talk of stores spying on you, using your phone's bluetooth or wifi radio to track your movements, too. But then Apple decided to randomize your phones wifi MAC address when searching for access points, kinda killing that idea.
