When Apple presented to the world its new Face ID with the iPhone X, many manufacturers launched to emulate that facial recognition. Nevertheless, Living It will once again be ahead of the curve with a version of Face ID capable of rivaling the original and, above all, going a step further in 3D detection technology and artificial intelligence applications.
Vivo Face ID: this is how they will compete with Apple's sensor
Face ID It remains, for the time being, the best facial sensor currently available in the Apple ecosystem. Many Android manufacturers have tried to emulate its performance, but the truth is that neither Android's native option nor third-party options truly measure up in terms of reading depthfalse positive rate and protection against impersonation attempts. This is because, generally speaking, appropriate technologies are not used; instead, other methods are employed to scan the face and use it to unlock the mobile phone, usually relying solely on the 2D front camera.
On the simplest Android phones, facial recognition is limited to comparing an image of the face with the front camera, without additional sensors. This system is fast and cheapBut it is also much easier to fool with a photo or video, and it usually fails when there are changes in lighting, accessories, or variations in the user's appearance.
Living Vivo has decided to do things right, and, given that they're going to compete with Apple, they want to do so by trying to surpass them. That's why they're already showing the first tests of their own sensor, capable of detecting faces from a greater distance and with greater accuracy. Vivo's proposal isn't just a simple facial unlock: we're talking about a 3D recognition platform designed for biometric authentication, augmented reality, and motion capture.
Furthermore, Vivo's development is part of a broader trend within the sector: several Chinese manufacturers are testing mobile phones with Invisible selfie camera under the screen combined with advanced 3D facial recognition. This type of solution aims for completely clean screens, without notches or holes, but with secure systems comparable to or better than Face ID, where brands like Xiaomi, OPPO, or Vivo itself They are destined to play a key role.
Vivo's TOF 3D: an optical radar with 300.000 points
Living has put all the meat on the grill with this new method of facial recognition. How? With a 300.000-point sensorup to ten times more than Apple's Face ID. This system is called TOF 3D, acronym for Time of Flight or time of flight, and it works differently than the structured infrared light that Apple uses.
With this method, light is projected from the sensor towards the face and the time it takes to return is calculated, thus determining the three-dimensional shape of the faceEach point captured is based on the time it takes for light to bounce, allowing for the creation of a very accurate depth map, closer to the workings of a optical radar than a simple conventional camera system.
In practical terms, this means the phone doesn't just see a relief silhouette, but a highly detailed model with depth information that makes any attempt to trick the system with masks or photographs much more difficult. Furthermore, with this technology, you can unlock your phone from a distance of up to three meters, larger than Apple's and superior to most 3D solutions from other Android manufacturers.
The key to Vivo's 3D TOF isn't just in the hardware. The system also relies on artificial intelligence algorithms which interpret the 3D map and learn from gradual changes in the face (beard, glasses, makeup, hairstyles). This combination of TOF sensor and neural networks allows for maintaining a high level of security even with constant variations in appearance of the user or in adverse lighting conditions.
Comparison with other 3D facial recognition systems
To better understand the bet LivingIt is worth comparing its technology with other advanced facial recognition systems currently available or announced on the mobile market. Among the most notable are: Apple Face ID, the 3D system of Xiaomi Mi 8 Explorer Edition and the retractable module of the OPPO Find X, in addition to intermediate solutions such as the Active Stereo from MediaTek.
In the case of Apple, Face ID combines front camera, infrared camera, dot matrix projector, and support light to generate a 3D model of the face with approximately 30.000 points. This is complemented by the neural engine integrated into the processor to analyze facial variations in real time and minimize the probability of false positives, which Apple places at one in a million.
Xiaomi, for its part, is also betting on a system of structured 3D light The Mi 8 Explorer Edition features a dot-matrix projector, infrared emitter, auxiliary TOF sensor, front-facing camera, and distance and light sensors. While exact dot counts haven't been specified, the philosophy is similar to Apple's: a complex array of components on the front to capture facial depth.
El OPPO Find X It integrates its 3D recognition module into a retractable system that conceals an infrared projector, distance sensor, front-facing camera, and a dot matrix of approximately 15.000 emitters. It's a very advanced solution, although its mapping resolution is lower than that of Face ID and, above all, far below the... 300.000 points of Vivo's 3D TOF.
In contrast to these structured light-based systems, Vivo proposes a different approach with 3D TOF: instead of projecting a fixed pattern of points, it sends light pulses and measures the return time, simplifying the hardware architecture and allows for more flexible integration into the front of the device, without sacrificing a much higher depth resolution.
Advanced uses: beyond facial unlocking
The accuracy of this new sensor also means that since Living other possible uses are questioned, such as control the mobile using facial gesturesThe system can recognize subtle facial or head movements and transform them into commands, opening the door to new forms of interaction without touching the screen, especially useful in hands-free scenarios or accessibility.
New applications are also being considered augmented reality And, of course, new potential uses for artificial intelligence. The ability to detect objects and people from several meters away, with precise three-dimensional reconstruction, makes Vivo's 3D TOF sensor an ideal tool for more immersive AR experiences, both with the front camera and the rear camera if the manufacturer decides to integrate it on both sides of the device.
There is talk of the possibility of doing full body scans that can be used as models when taking selfies, aiming to improve upon the usual beauty modes of Chinese mobile phones. In turn, it could be used to sell products like clothing, by showing how a garment would look on your fully scanned body. This fits with the idea of ​​creating a realistic 3D avatar from the user, which can then be used in shopping apps, games or social networks.
In addition to more accurate authentication services and improved selfie quality, Vivo's new sensor technology could be used for the recognition of gestures and emotionsBy interpreting facial geometry and microexpressions, applications could adapt the interface, camera filters, or displayed content depending on whether the user smiles, frowns, or is surprised.
While some of these applications are still in the exploratory phase, the truth is that Living The sensor is already being showcased and appears to be delivering on its promises. The Chinese company continues to stand out as one of the most innovative in the market, one that seeks alternative paths and, most importantly, is succeeding. Its 3D TOF technology is ready to be integrated into commercial devices and position itself as one of the leading solutions. more advanced 3D facial recognition within the Android ecosystem, bringing this operating system closer to the security and convenience experience that was previously dominated by Apple.
