behind a simplified conceptual model
One example of a product with a simplified conceptual model is Apple
iBeacons (introduced in chapters 2 and 4). Imagine a user walks into a store
for which they have a an app installed, their location is detected using
iBeacons, and they are sent a push notification about a special offer. It’s good
enough for that user to understand that the store knows they are there, thanks
to the beacons, and the store has sent them a message.
