Android brings together a good part of its accessibility functions under Android Accessibility Suite, the evolution of the old Talkback. The latest innovation in this accessibility suite adds the ability to use facial gestures to manipulate the mobile.
This new feature arrives in version 220.127.116.111995842 beta of the accessibility suite under the name of Camera Switch, within accessibility with switches. Until now, Android natively allowed the use of switches by external devices connected via Bluetooth or USB.
Manage your mobile with gestures
The Android accessibility suite has just added a major improvement in accessibility: support for using the mobile’s own camera to recognize facial gestures and use them as switches to perform various actions.
Accessibility switches were already part of the Android Accessibility Suite, although they required the use of an external device connected to the mobile via Bluetooth or USB. With this new feature, nothing more is required than the front camera of the mobile, thanks to the Camera Switch, a new parameter available in the Android accessibility options after installing the latest version of the accessibility suite on a compatible mobile .
This option allows you to perform tasks on your mobile such as use scrolling, home key, go back, open notifications, then select or view Android quick settings using gestures facial. To prevent these functions from being activated during normal use of the mobile, it is recommended to also assign a switch to activate and deactivate gesture recognition.
As for the available gestures, you have to open your mouth, smile, raise your eyebrows, look to the left, look to the right and look up. Obviously, the mobile must keep the front camera of the mobile on to recognize the different gestures and launch the action when there is a positive recognition.
To avoid accidental activations, from the accessibility options, it is possible to test the recognition and modify the sensitivity and duration of the gesture, to assign a more comfortable value.
While this accessibility feature appears in the version of the Accessibility Suite preinstalled in Android 12, it is not exclusive to this version. In fact, we were able to test it without problems on a mobile with Android 10, so it is expected that it will also be extended by the previous versions.
