Google's maps go indoors with new mobile feature

Google wouldn't say why the feature would work only on Android devices.

To help encourage brand loyalty...duh

Terrorists?? I do hope they do not research soft targets! Airports etc with this new Google technology!!

@aboDofuIsSpicy enough Japanese user who forget to password their Wifi connection ;)

The software is programmed to automatically change to a different floor in a building when the user does.

Wow, not even the spaceship in the original "Alien" movie had this - and got eaten...so will there be a follow-up software for Japanese not to encounter any Aliens around them?

Have you ever tried to get wifi in Japan? Good luck.

You are misunderstanding why the wifi was mentioned. Wifi hotshots with known location, which are on Google's database, are used for the calculating your location using triangulation or etc with combination of cell towers (also the location of them are known) as it is difficult to get gps signal indoors.

This is great. Now people will not be able to complain about the lack of English signs for tourists.

The hard part though will be finding some wi-fi for free to connect to. This country is back in the stone age on that.
