A variation of the latter technique is used to accomplish Portrait Mode on iPhone 7 Plus. For example, light detection and ranging (LIDAR) uses pulses of laser light, time-of-flight calculations, positioning equipment and other assets to generate highly accurate 3D scene composites.Īlternative methods replace lasers with patterned infrared light, while others rely on known optical distortions combined with complex computational algorithms. It boils down to 2D imaging versus 3D imaging - 2D is used for fingerprint scanning, while facial recognition is now in the realm of 3D.Īt the heart of modern 3D imaging is depth mapping, a technology that creates a topographic model of an object or environment using specialized equipment.

A slew of hurdles stand in the way of implementation, however, ranging from software design, hardware certification and the creation of a verification database, among other backend assets.Įven if a 3D camera is unveiled as part of "iPhone 8's" arsenal of new features, it is unlikely to serve as a complete replacement of Touch ID.Īs it stands, facial recognition in its current form is simply not as secure as fingerprint-based authentication methods. A hands-off, no-touch security solution like facial recognition is preferable to contact technology like fingerprint sensors, which require user interaction. Since Kuo's February note hit media outlets, analysts and pundits have glommed on to the idea of a face-detecting iPhone. Whether those systems will be ready in time for inclusion in "iPhone 8" remains unclear, but a 3D FaceTime camera is a huge step toward that goal. Though Kuo did not explicitly say the camera system would be used for bio-recognition - face detection - operations, the analyst in January said Apple is developing facial and iris recognition technologies in hopes of one day replacing Touch ID.

By adding an infrared transmitter and receiver to the usual FaceTime camera, the company will be able to conduct accurate depth mapping functions for 3D modeling, perfect for creating gaming avatars and capturing 3D selfies. Most recently, KGI analyst Ming-Chi Kuo last month said checks with supply chain sources suggest Apple is looking to integrate a " revolutionary" front-facing camera system capable of 3D sensing. Being the 10th anniversary of iPhone's initial release in 2007, expectations are high, now bordering on mythical. The device is expected to sell as a standalone model priced above "iPhone 7s" and "iPhone 7s Plus" refreshes.Īs Apple's traditional fall launch timeline approaches, analysts and industry insiders are coming out of the woodwork to offer their predictions on what advanced technology Apple plans to incorporate in the next-generation handset. 'iPhone 8' concept rendering by Marek Weidlich.įor 2017, Apple is widely rumored to launch a high-end iPhone that comes packing a litany of exotic technologies, including an OLED display, wireless charging, glass-sandwich design, in-screen Touch ID and more.
