I'm curious to see how smooth the interaction is with this product. It seems it could be awkward to ask a stranger who doesn't speak your language to look at your iPhone and click buttons to communicate with you.

On the other hand, if they can make it feel "magical", it will be an impressive achievement.

I often got lost in Japan, and ask random strangers to show me where to go on a gps map, or show an address in an email or have them look at instructions etc. It might not work in other countries, but in japan it's very smooth.

Apart form that, I think the presence of the Yes/No buttons is very thoughtful. You don't want a stranger to have to think about the kind of answer you're asking for.
