At launch, the screens will feature all sorts of content, like delays, outages, and, of course, ads (which bring in $100 million in revenue for the MTA each year, but mostly in paper signage). Yet its most powerful interaction for many will likely be its map, which features a one-tap navigation system. Seriously. You look at the map, you tap your intended destination, and the map will draw your route, including any transfers along the way. It’s an interface that puts Google Maps to shame.
