Apple patent for iOS device facial recognition goes live

At least your iPad will remember who you are.

Per Free Patents Online, a recently published patent application shows how future iOS devices could use a forward-facing camera to recognize an individual user, whereupon the device could automatically customize applications, settings and features to a user’s personal preferences once they pick up the unit.

Entitled “Low Threshold Face Recognition,” the patent describes a low-computation solution for quickly and accurately recognizing a user.

The filing provides a simple way for multiple users to share a single device, like an iPad. Each user could customize their personal profile with unique wallpaper, applications and settings, and that profile would be immediately accessed once the iPad recognizes a user’s face.

Apple’s application notes that robust facial recognition systems that work in various lighting conditions and orientations can be taxing on an electronic device, requiring resources and draining battery life.

Its solution would reduce the impact of lighting conditions and biometric distortions on an image. The filing describes a “low-computation solution for reasonably effective (low threshold) face recognition that can be implemented on camera-equipped consumer portable appliances.”

Rather than aggressively analyzing a user’s entire face and using up time and resources, Apple’s concept would rely on a “high information portion” of a human face. Potential high information portions could include eyes, a mouth, or the tip of a user’s nose.

By recognizing the individual features on a user’s face, the system could scale the distance between someone’s eyes and their mouth. That distance could then be measured against the reference image originally captured by the user in order to confirm it is in fact the same person.

Apple’s application notes that its facial recognition capabilities could be constantly active due to lower power consumption. This means a user could simply point an iPhone or iPad at their face, without pressing a button, and have the screen automatically turn on and unlock the device.

This could be accomplished through an “orange-distance filter,” which would capture the “likely presence” of a human face in front of a camera. This filter would also be used to detect a person’s skin tone, and measure the distance of their face from the camera.

Once a user has been recognized, the facial recognition technology could not only grant them access to the device, but also customize its settings based on a unique user profile. Each user would be presented with a personalized configuration, as an iPhone or iPad would be able to “modify screen saver slide shows or other appliance non-security preferences,” the application reads.

The proposed invention, made public this week, was first filed by Apple in June of 2009. It is credited to Robert Mikio Free.

Stay tuned for additional details as they become available.
