Motion Cues
A native Android overlay that turns vehicle movement into a quiet visual reference above other applications.
The work, not a mockup.

What exists.
Motion Cues uses device sensors and a non-touchable system overlay to display motion-reactive dots while leaving the application underneath fully usable.
Where it resisted.
The cues must remain helpful across orientation changes and sensor noise without blocking touches or demanding attention.
What I changed.
I built calibration, adaptive intensity, smoothing, stillness behavior, presets, Quick Settings controls, foreground-service reliability, and the Android release path.
The obvious implementation was not the product.
Keep the cue layer deliberately restrained and non-touchable; usefulness depends on becoming part of the background.
Current proof
03- Native sensor overlay, foreground service, notification controls, and Quick Settings tile are implemented.
- Motion mapping adapts to orientation and provides accelerometer fallback.
- A signed release bundle and Play Store visual assets were produced.
What this build changed.
A system-level product can require deep engineering while its successful interface remains almost invisible.
