Doubts and Speculation Surround Apple's Onstage Face ID 'Fail' During iPhone X Keynote
Wednesday, 13 September 2017 Yesterday at a media event held in Apple Park, Apple announced its much-anticipated all-screen 5.8-inch iPhone X, which features a next-generation facial authentication system called Face ID for unlocking the smartphone in lieu of a home button with Touch ID.
During the keynote at the Steve Jobs Theater, Apple software engineering chief Craig Federighi took to the stage to demo Face ID. However, much to his chagrin, the facial recognition technology appeared to fail at his first attempt to unlock the iPhone X, forcing Federighi to switch to a backup device to get the demo moving.
Some observers have leapt on the moment as an indication that Face ID is unreliable or a yet-to-be-perfected technology that's unfit to replace Touch ID fingerprint authentication. Vice News even went so far as to link the onstage incident to a sudden drop in Apple's share price. Since the demo aired, however, three competing theories have been put forward to explain the apparent "failure".
One theory is that Apple has adopted the same reboot security measure on the iPhone X that is found on iPhones with Touch ID, and this is what stalled Federighi's Face ID demo. The moment when he tries to unlock the iPhone X with his face, a closer look at the presentation screen reveals the words "Your passcode is required to enable Face ID". As several contributors on Quora have pointed out, a similar message is seen when an iPhone with Touch ID is first switched on.
This suggests someone forgot to enter the passcode on Federighi's iPhone X after a reboot. But if that were the case, the message likely should have stated, "Face ID requires your passcode when iPhone restarts", which more accurately reflects the equivalent message Touch ID phones display after a reboot.
Another explanation put forward is that several unsuccessful attempts had already been made to unlock the device prior to the onstage demo, since Federighi only tries to authenticate Face ID twice before the passcode screen appears, whereas Touch ID takes five consecutive failed attempts before requiring a passcode. Possible, but unlikely.
The third, more concerning explanation, of course, is that Face ID simply failed to recognize the Apple executive, suggesting the feature has accuracy issues that the company is still working to resolve. Indeed, while Face ID was generally lauded by the media during hands-on demonstrations after the keynote, at least one journalist reported "plenty of missed unlocks" during their time with the iPhone X, which they called "a little worrying".
Apple claims Face ID can recognize a user's face under a variety of conditions and in poor light, despite everyday changes in appearance, such as applied make-up or beard growth. It is also said to boast a mismatch error rate of 1 in 1,000,000, compared to 1 in 50,000 for Touch ID, thanks to multiple neural networks built into the iPhone X's dual-core A11 bionic neural engine. With the iPhone X officially up for pre-order on October 27, the proof of the pudding will be in the eating.Related Roundups: iPhone 8, iPhone X
