Washington: American tech giant Google is developing a new accessibility feature for Android that will let users control a phone using facial expressions like a smile or raised eyebrows. According to The Verge, the 'Camera Switch' feature has arrived with version 12 of Android's 'Accessibility Suite' app, released alongside Android 12's fourth beta. The new version of the app isn't available via Google Play just yet, but reports suggest that there's an APK to side-load if you want to give it a try. Facial expressions (which also include looking left, right, or up) can be used to access a number of controls, ranging from scrolling, going home, or viewing quick settings or notifications. Screenshots show that users can adjust how sensitive the software is when recognizing expressions, which should hopefully limit the potential for accidental activations.

It's not hard to see how the feature could be useful for anyone who might struggle with certain touch controls. Unlike voice commands, facial expressions are silent, which could make the controls easier to use in public or in quieter environments. Android has received a number of accessibility features with recent releases, which like these facial expression controls are aimed at making the phones easier to use for people with disabilities. Last year's Android 11, for example, delivered improvements to the operating system's voice control feature. Earlier in the year, Google released a collection of other accessibility updates including customizable 'Action Blocks', which let users assign custom actions to large on-screen buttons. The arrival of the new feature alongside the latest Android 12 beta suggests that it'll officially launch as part of the operating system update later in the year. But, as per The Verge, this latest version of the Accessibility Suite app appears to be backwards compatible with Android 11, suggesting it might not be exclusive to Android 12.
