HandPointer\n\nHandPuntator is a Python-based system that enables hands-free computer control using real-time hand tracking and gesture recognition powered by MediaPipe, translating finger landmarks into precise cursor movement and configurable actions like clicking, dragging, and scrolling for accessible, touch-free interaction scenarios .\n\nKey contributions\n- Implemented robust real-time hand landmark tracking and gesture mapping with MediaPipe Tasks to support low-latency, smooth pointer control and discrete actions .\n- \tDesigned a modular input layer that maps index-finger kinematics to cursor motion and pinch-orientation gestures to clicks and drags, making behaviors easy to extend or swap .\n-\tBuilt an experimentation pipeline with OpenCV for video capture and visualization, enabling rapid iteration on gesture thresholds, smoothing, and UX tuning .\nWhat it showcases\n\n- Computer vision integration: applying MediaPipe’s Gesture Recognizer/Hands pipeline to interface design and human-computer interaction .\n-\tSystems thinking: translating continuous hand pose data into stable, user-friendly controls through filtering, debouncing, and gesture state machines .\n- Accessibility and HCI: enabling touch-free control for mobility and hygiene contexts, and prototyping alternative input methods .\n\n## Gesture set\n\n\n- Hand open: move the pointer by tracking the index fingertip position in real time, with smoothing to ensure stable motion.\n- Index + middle finger touch: perform a left-click when the index fingertip contacts the middle fingertip, with a short debounce to prevent accidental multiple clicks.\n\n## Run Locally\n\nyou will need python 3.12 to use\n\n1: Clone the git repo and go to directory\n\n```bash\n  git clone https://github.com/Zunza5/HandPointer.git\n  cd HandPointer\n```\n\n2: Create and activate a virtual environment\n\nmacOS/Linux:\n\n```bash\n  python3.12 -m venv .venv\n  source .venv/bin/activate\n```\nwindows:\n\n```bash\n  python3.12 -m venv .venv\n  ..venv\\Scripts\\Activate.ps1\n```\n\n3: Install dependencies\n\n```bash\n  pip install -r requirements.txt\n```\n\n4: run main.py\n\n```bash\n  python3.12 main.py\n```\n## Authors\n\n-
