Mobile device makers are eyeing 3D cameras to power augmented reality apps and security via 3D face recognition.
With several major mobile device makers expected to include 3D imaging technology in their next-generation smartphones, it's a good time to contemplate the potential applications of this technology.
Today, thanks to advanced signal processing, 3D cameras are able to interpret and represent 3D imagery even better than humans, enabling some pretty compelling applications--including biometric security. A front-facing 3D camera allows the device’s owner to simply look at the screen to unlock it.
Face-recognition authentication has gotten a bad rap in the past, but it’s important to emphasize that this isn’t your father’s facial recognition technology. Mathematically precise depth perception technology means that a picture, video, or even a mask of your face won’t be able to unlock it—it needs to be the real thing.
Authentication via 3D face recognition would also allow mobile device manufacturers to replace the space currently occupied by fingerprint scanners with more screen. Perhaps even more importantly, the process of authentication now becomes transparent, as there is nothing to touch--the user simply interacts with the device as they always have.
