Build better posture with Postura

Build better posture with Postura
View Report

Project Overview

Poor posture is a pervasive problem, particularly for those spending long hours working at desks or engaging in sedentary activities. This project aimed to address the issue by creating a wearable posture-monitoring vest integrated with a table unit for real-time analytics and actionable insights. The system is designed to improve posture, reduce strain, and foster healthy habits.

Our Solution

We developed a system combining a wearable vest with a table unit hub that monitors posture in real-time and provides advanced analytics to encourage corrective action.

1. Wearable Vest

  • Features:
    • Equipped with four sensors: two on the shoulders and two on the spine for accurate posture tracking.
    • Lightweight and comfortable for extended wear without irritation.

2. Table Unit

  • Features:
    • Serves as a hub for data collection and visualization of analytics.
    • Delivers real-time actionable feedback to help users improve their posture.
    • Designed for scalability in workplace wellness programs.

Development Journey

  • Iteration & Innovation: We started with 2 IMUs and homemade flex sensors but found the results too noisy. After several iterations, we refined the system to include 4 sensors for more accurate tracking.
  • Rapid Prototyping: Using a combination of sewing machines, 3D printing, and soldering, we created 5 working prototypes in just 2 months.
  • Simplification: Feedback from mentors helped us focus on slouch detection, ensuring the system did one thing and did it exceptionally well.
  • DIY Excellence: From building a custom battery pack to integrating two ESP microcontrollers into a compact case, every aspect of the product was thoughtfully designed and executed.

My Role

  • Identified and defined the problem.
  • Led ideation and brainstorming sessions for the wearable and table unit design.
  • Assembled hardware and integrated sensors.
  • Developed the analytics engine for real-time feedback.
  • Conducted iterative testing and refinement based on user feedback.

Key Outcomes

  • Reliable Posture Tracking: Integration of 4 sensors (2 on shoulders and 2 on the spine) to accurately detect slouching.
  • Advanced Analytics: The table unit collects posture data, visualizes it, and delivers actionable feedback to users.
  • Simplified Design: Focused on slouch detection, ensuring the system excels at its core function.
  • Prototyping Milestones: Completed 5 iterations in 2 months using sewing machines, 3D printing, and custom-built battery packs.
  • Scalable Design: Modular system allows for further integration and scalability for workplace wellness programs.

Lessons Learned

  • Do One Thing Well: Focusing on slouch detection helped us deliver a highly reliable and effective product.
  • User-Centric Iteration: Feedback loops and rapid prototyping ensured the product met real-world needs.
  • Attention to Detail: From the hardware to analytics, every element impacts the user’s experience.
  • Empathy-Driven Design: Understanding the user’s pain points was critical to designing a meaningful solution.

This project wasn’t just about building a tool—it was about creating a meaningful solution to a problem that impacts productivity and health. It reinforced the idea that designing for simplicity and functionality leads to innovation.
