MotionScroll

Scroll through your Android screen using simple head movements. Built with Jetpack Compose and ML Kit.

MotionScroll is an Android application that leverages the front camera and accessibility features to enable hands-free scrolling based on head tilt detection.

Important Note: To avoid unintended scrolling when navigating within the application settings or other parts of your device, it is critically important to use the shortcut overlay to disable camera-based head tracking before you start navigating. Head tracking remains active while the app is open, and attempting to navigate menus or settings with head tracking enabled and without the shortcut overlay to quickly disable it will likely result in unwanted scrolling. Always use the shortcut overlay to toggle tracking off when you need to use standard touch or navigation methods.
