Face Control is a FREE and open-source accessibility app developed by Obstino. It uses front camera to control your device using your face.
Face Control enables smart (camera) switch access for disabled users, who are unable to use their Android device using touchscreen.

Primarily, Face Control uses front camera to detect face gestures: smile, eyebrow raise, eye movement, eye wink, and mouth open.
With Face Control, you can also use physical switches that connect to the Android device using either Bluetooth or USB (such as from AbleNet, Enabling Devices, RJ Cooper, and Tecla).
Face gestures act as a “camera switch”, which means a disabled user can fully control their Android device only using their face (for example by smiling and raising the eyebrow).
For example, Face Control uses the detected smile to select a point on which to tap on screen, or use combination of eyebrow raise and smile to select Face Control menu actions such as scrolling inside web browser.
