Surprised to see all the negative sentiment here. Besides the true point that voice-only interaction is a bad idea for public spaces, I think this is a very cool device with lots of potential.

I'm especially excited about the fact that they found a really low-barrier user interface for using CV and AR-type functionality -- like, without having to put on silly glasses, and without having to use a second device with a screen in addition to the pin.

Come on, this is cool! Or would you have designed (and built!) a better device?
