From the article I've learnt that it's voice controlled. If it could be just a peripheral for a phone that catches hand gestures and controls multimedia, it may be a fun thing for a week, and probably a new niche way of using and controlling devices. With phone-enabled home assistant app - an integration with it too. And decoding sign language as an obvious bonus and a social value point.
Honestly, I could've bought it if it was that and also customizable with free gesture recording and assigning to commands.
