Curious how thick the transparent material is and what an infrared camera would see when it's in opaque mode and occupied by people.

>Around the world, public toilets get a foul rap. Even in Japan, where restrooms have a higher standard of hygiene than in much of the rest of the world.......

I would have put anywhere in stead of much.

So the question is, are their any place on earth where restrooms have a higher stand of hygiene than in Japan?

I wonder if this was built with security in mind. How easy would it be to tamper with the opaque switch?

Also is it fail-safe? Does it turn clear when the power fails?

It could be very embarrassing and/or result in some liability issues if not.

I didnt see anything in the article about how they handle privacy when you're actually using the toilets. How will they accomplish this part?

Upon reading the details, quite brilliant!
