Here's an update on my 2010 posting Going Inside the Store. Has you phone ever displayed a message saying you'd get better map results if you enabled WiFi? That's because companies like Skyhook, Apple, and Google send people to public places to correlate WiFi signal strength with locations. Then they use the information to more accurately determine your location, which is especially important when line-of-sight to the GPS satellites is not possible.
Retailers like Home Depot, IKEA, and Macy's have provided store floor plans to Google so that Android maps actually extend from the streets to the aisles, making it easier to navigate big-box stores. Similar efforts are ongoing for airports, malls, and arenas. Wouldn't it be nice for the mapping on your phone to take you directly to your seat in the stadium, your gate in the airport, and a product on the shelf?
Here's a short video showing how you can navigate inside an IKEA store using your phone.
