Source: Apple working on rear-facing 3D laser system for new iPhone that will enable better depth detection for AR apps and improved autofocus
The addition will make future iPhones far better suited to the AR experiences being created by developers using the ARKit development platform.
Context & Ripple Effects
This July 2017 Fast Company report is the earliest signal in a multi-year leak trail: five months later, Bloomberg independently reported Apple was working on a rear-facing 3D sensor, and by September Apple had shipped the front-facing half of the story with face-tracking depth data coming to ARKit on iPhone X.
What makes the rear-facing piece matter is the developer side: ARKit had just turned every iPhone into an AR distribution channel, but its depth sensing was software-inferred. A laser-based depth system would give those developers hardware-grade depth — and the roadmap kept expanding, from the same 3D sensor module planned for iPad Pro and higher-end 2020 iPhones to confirmed rear depth cameras in 2020.
First-order effects
- ARKit developers gain hardware-grade depth data instead of camera-inferred estimates, making occlusion, measurement, and object-placement apps materially more accurate on the affected iPhones.
- Autofocus improves as a direct side effect of the laser system, so the change lands in the camera experience of every user, not just AR app users.
Second-order effects
- A shared depth-sensing module across iPhone and iPad Pro gives ARKit developers one consistent hardware baseline across Apple's device lines, lowering the cost of targeting AR features at the whole installed base.
- Once depth sensors become a differentiator on flagship devices, they pressure the rest of the premium smartphone market to add comparable rear depth hardware to stay competitive on AR capability.
Third-order effects
- If the leaked sequence holds — rear depth sensors, then the AR/VR headset and glasses Bloomberg reported as following — the iPhone functions as the bridge device that seeds an AR developer ecosystem before dedicated AR hardware exists.
- Depth sensing becoming standard phone hardware turns the camera stack into general-purpose perception infrastructure, a foundation that outlasts any single AR app category.
The trend: Smartphone makers are converting cameras from image capture into depth-sensing perception systems, using the phone to build an AR developer base ahead of dedicated AR hardware.
