Cebian is an open-source Android gesture and single-handed productivity suite that replaces Samsung One Hand Operation+, Quick Cursor, and FooView. It provides advanced edge triggers, floating OCR, and app freezing capabilities for large screens, operating entirely on-device via Shizuku or Root.
Technical Overview
This application leverages Android Accessibility Services combined with Shizuku IPC, Root fallback executors, and optional LSPosed modules to command system-level actions and background processes. It executes complete offline text extraction using local ML Kit and PaddleOCR ONNX models, processing word segmentation natively via a CppJieba JNI bridge. System overlays are managed by independent WindowManagers equipped with real-time Gaussian blur and MaterialKolor dynamic theming.
Core Features of Cebian
- Universal Edge Gestures replacing Samsung OHO+ with customizable multi-angle triggers, anti-mistouch rules, and native OEM freeform window integration.
- Floating Reachability Pointer combining a virtual joystick with radial actions to enable complete single-handed control on large displays.
- Offline On-Device OCR extracting text, QR codes, and SMS verification codes using local ONNX models without cloud trackers.
- Advanced Sensor Motions recognizing six-direction device shakes, desk-flip muting, and accelerometer-based back-cover double-taps to trigger over 50 actions.
Compatibility & Quick Setup
Requires Android 12 or newer—install the APK and grant the required system privileges via Shizuku or Magisk root access.
