The iPhone 6 is getting Dark Knight-style sonar mapping By Buster Hein • 11:43 am, December 7, 2012 At the end of Chris Nolan’s 2008 movie The Dark Knight there's a scene in which Batman uses Lucius Fox’s sonar concept to turn every cellphone in Gotham City into a huge sonar-based live map in order to find The Joker. Back in 2012 it was rumored that Apple was interested in applying that same technology to its then-a-gleam-in-Apple’s-eye iPhone 6 handset. The tech would allow Apple to integrate audio sensors into its displays, which could detect the proximity of objects to your iPhone: interrupting your podcast app to alert you that a fast-moving large object is approaching you, for example.Now obviously it’s a bit difficult to disprove this report given that the iPhone 6 itself is still technically a rumor. This one was also based on an Apple patent, which shows that someone in Cupertino at least took it seriously enough to file the necessary paperwork. However, we’ve heard nothing about it since, while more and more details of the iPhone 6 have been leaking on what seems like a daily basis. Maybe one to chalk up for the unsubstantiated rumor pile!Which is a real shame because if Apple could’ve figured out a way to license Morgan “Lucius Fox” Freeman’s voice for a next generation Siri the combo could have been a total crowd pleaser.
