## What it is
Semaphore is a Python application that turns your full body into a keyboard using flag semaphore gestures. It uses OpenCV and MediaPipe pose detection to read body landmarks from a webcam and translates arm and leg positions into keystrokes.

## Use cases
- type letters using full-body semaphore gestures
- control a computer keyboard with webcam pose detection
- experiment with gesture-based text input
- build accessibility input methods using body movements
- demo computer vision pose tracking projects

## When to choose
- you want a fun, experimental webcam-based gesture keyboard
- you need hands-free typing driven by body poses
- you want a Python/OpenCV/MediaPipe starting point for gesture input projects

## When to avoid
- you need fast, reliable everyday text entry
- you require production-grade accessibility software
- you need Windows or Linux keyboard support out of the box without modifications

## Facets
- artifact type: application
- maturity: experimental
- function: computer-vision, speech-recognition
- domain: computer-vision, developer-tools
- platform: python, cross-platform
- tags: gesture-recognition, mediapipe, opencv, pose-detection, virtual-keyboard, accessibility, flag-semaphore, macos
