Problem Statement
Poor posture during extended computer use leads to chronic pain, reduced productivity, and long-term health issues. While many people are aware of the importance of good posture, they often forget to self-correct during focused work.
Existing solutions rely on intrusive wearables or lack real-time feedback. S.P.I.N.E. provides a non-invasive, privacy-focused solution using computer vision and subtle haptic feedback to promote healthier sitting habits.
Solution Overview
Camera Detection
MediaPipe-based computer vision analyzes posture in real-time using existing webcams or dedicated cameras.
Wearable Feedback
Custom wristband with vibration motors and LED indicators provides gentle, non-intrusive posture correction reminders.
Desktop App & Cloud Backend
Desktop application for posture monitoring with a cloud backend for user management, session tracking, and posture data storage.
Technical Architecture
Computer Vision Module
Python-based application using MediaPipe Pose for real-time skeletal tracking. Analyzes neck angle, shoulder alignment, and spine curvature to detect slouching and forward head posture.
Wearable Device
ESP32-based wristband with Bluetooth connectivity. Receives posture alerts and triggers vibration patterns or LED sequences based on severity and user preferences.
Cloud Backend
A containerized backend service deployed to a personal VPS, handling user accounts, organization licensing, posture sessions, posture events, and aggregated stats with token-based access control.
Privacy Design
Posture analysis runs locally on the user's device. Video and skeletal data remain on the device. The cloud backend stores user accounts, organization licensing, posture sessions, events, and aggregated statistics.
