DriveSwipe

DriveSwipe is an Android app for touchless in-car media control using camera-based hand gestures. It uses CameraX + MediaPipe for live gesture recognition and maps recognized gestures to media actions (track, play/pause, volume).

Features

• Compose multi-screen UX (Home, Setup, Gestures, Modes, History)
• Foreground gesture service for reliable in-drive operation
• Day/Night operating modes (camera + proximity flow)
• Gesture mapping and tuning controls in-app
• DataStore-backed persistent settings
• Runtime gesture history feed for quick validation
• Branded launcher icon and signed release build support

Gesture Set

• Pinch_Drag_Right -> mapped action (default NEXT_TRACK)
• Pinch_Drag_Left -> mapped action (default PREVIOUS_TRACK)
• Two_Finger_Point -> mapped action (default PLAY_PAUSE)
• Thumb_Up -> mapped action (default VOLUME_UP, repeat by tick interval)
• Thumb_Down -> mapped action (default VOLUME_DOWN, repeat by tick interval)

Stack

• Kotlin
• Jetpack Compose + Material 3
• AndroidX Navigation

Requirements

• Android Studio (latest stable recommended)
• Android SDK 34
• Min SDK 26
• Front camera device (proximity sensor optional but recommended)

   • keyPassword
3. Build release:
   • ./gradlew.bat :app:assembleRelease

Repository Layout

• app/src/main/java/com/example/driveswipe/MainActivity.kt - app host + permission/service orchestration
• app/src/main/java/com/example/driveswipe/DriveSwipeApp.kt - app UI shell and screens
• app/src/main/java/com/example/driveswipe/GestureService.kt - foreground service and media action dispatch
• app/src/main/java/com/example/driveswipe/GestureRecognizerHelper.kt - inference pipeline and pinch/gesture logic
