Google Working on Pixel 6 Face Unlock Feature, Could Depend on Under-Display Fingerprint Sensor: Report

Google is said to be continuing its work on bringing the facial recognition feature to the Pixel 6. Future devices, including the upcoming the Pixel 7 series also expected to benefit from this feature. According to a new report citing industry sources, Google could be working on using the under-display fingerprint sensor in conjunction with the face unlock feature. This approach is reportedly energy efficient and is expected to work on a wide range of Pixel smartphones. Notably, the Pixel 6 Pro was rumoured to come with face unlock, however, the feature was reportedly pulled close to its launch.

According to a 9to5Google report, Google is developing a version of face unlock that also uses the under-display fingerprint sensor. This new feature reportedly works by lowering the recognition threshold for the fingerprint sensor when the smartphone partially recognises a face. The accuracy requirement of a fingerprint match would be significantly lowered, as per the report.

Notably, this new feature does not require any new hardware to function as intended. As such, this approach could bring the face unlock feature to both Pixel 6 and Pixel 6 Pro, and Google is reportedly testing this feature on these smartphones.

The use of face unlock with the fingerprint sensor could also function on the Pixel 6a and other a-series Google smartphones, according to the report. Even the upcoming Pixel 7 and Pixel 7 Pro could also utilise this feature. Notably, this approach is said to be more energy efficient than the traditional face unlock feature.

The report further mentions that this new approach could be Google’s ploy to get the best out of the below-average under-display sensor on Pixel 6 series smartphones. The recognition speed of the sensor is said to be sluggish in comparison to the speeds offered by other flagship smartphones like the Samsung Galaxy S22 lineup. Google is yet to officially announce plans to introduce a facial recognition-based system for its Pixel smartphone lineup.

Google Pixel 4 Face Unlock System Helping Researchers Detect Alzheimer’s: Here’s How

Google Pixel 4 series was plagued by many issues, but it seems that researchers have found at least one use case for its Face Unlock system. A team at University of California San Diego (UC SD) is using the IR sensor, arguably one of the best features of the smartphone, in detecting signs of Alzheimer’s disease. This sensor, coupled with a Dot projector, enabled face unlocking. The same sensor is now being used to record a person’s pupil’s response to specific tasks allowing researchers to identify cognitive impairments.

The Verge talked to one of the researchers of the team and he explained how the whole thing works. The team identified human eyes, specifically the pupil (black spot in the middle of the eye) as a metric for detecting Alzheimer’s — a disease in which brain cells die causing the patient to lose memory. The researchers recorded the response of the pupil to specific tasks that allowed them to identify cognitive impairments via an app. These impairments were based on the pupil’s functions during those specific tasks such as remembering a sequence of randomly spoken numbers.

The app is able to identify impairments by using the IR sensor that Google Pixel 4 uses for face unlock. The reason for using the IR sensor is because these cameras are better at detecting the difference between the eye colour and the pupil as compared to standard cameras, the researchers said. After recording the pupil’s response to specific tasks, the data is sent to the DigiHealth Lab at UC SD where researchers analyse it.

Alzheimer’s disease cannot be cured, but treatment can certainly help. It’s obvious that a smartphone’s feature will not be able to replace an equipment — which could be costing loads of money — specifically designed for detecting Alzheimer’s, but research such as this can provide a cost-effective way to give doctors a headstart for a treatment.
