Save Your Spine: Building a Real-Time AI Posture Coach with MediaPipe and Electron

Are you reading this while hunched over your keyboard like a gargoyle? Don't worry, you’re not alone. As developers, we spend thousands of hours in front of screens, often sacrificing our spinal health for that one elusive bug fix. In this tutorial, we are going to build "SpineGuard" —a cross-platform desktop application that uses Computer Vision , MediaPipe , and TensorFlow.js to monitor your posture in real-time. We'll leverage AI Posture Detection and Desktop Ergonomics logic to trigger alerts whenever you start slouching. By the end of this guide, you'll have a functional app that calculates your neck angle and lumbar curvature, sending "sit up straight!" notifications via WebSocket . The Architecture Before we dive into the code, let's look at how the data flows from your webcam to your desktop notifications. We use MediaPipe's Pose Landmarker to identify 33 body keypoints, focusing specifically on the ears, shoulders, and hips. graph TD A[Webcam Feed] --> B[MediaPipe Pose Engine]
