Inspiration

Poor sitting posture is a silent epidemic. Students, developers, and office workers spend 6–10 hours a day seated, often unaware that they’re slowly damaging their spines. Most posture-related problems don’t cause immediate pain, but by the time discomfort appears, long-term damage has already begun.

We realized that posture isn’t a motivation problem; it’s an awareness problem. People don’t need reminders or lectures. They need real-time feedback at the exact moment their posture breaks down.

That insight inspired us to build PostureSense.

What it does

PostureSense is a real-time, AI-powered posture monitoring web application. It: -Detects poor sitting posture live -Alerts users the moment they begin to slouch -Encourages small posture corrections before pain develops -Works directly in the browser — no wearables or external hardware required -PostureSense focuses on awareness-first posture correction, helping users build healthier sitting habits naturally.

How we built it

We built PostureSense as a lightweight, browser-based web application.

The front end was designed for simplicity and clarity using React, Next.js, and Tailwind CSS. For posture detection, we use camera-based input and AI-driven landmark analysis to evaluate alignment of the neck, shoulders, and upper back in real time.

The application is deployed using Vercel, allowing fast iteration and seamless performance during live demos.

This version represents Prototype 1, focused on validating real-time posture awareness.

Challenges we ran into

One of our biggest challenges was balancing accuracy and accessibility. We wanted posture detection to work reliably while remaining lightweight enough to run entirely in the browser.

Another challenge was ensuring a privacy-first design. We made a conscious decision not to store or record video data, which required careful handling of live camera input.

Finally, designing feedback that was helpful without being distracting took multiple iterations to get right.

Accomplishments that we're proud of

-Successfully built a real-time posture monitoring prototype -Delivered posture feedback without requiring any wearable devices -Created a clean, intuitive UI focused on user awareness -Implemented a privacy-first approach with no video storage -Completed a working end-to-end demo within the hackathon timeframe

What we learned

Through this project, we learned: -Real-time feedback is far more effective than passive reminders -Simplicity in UI is critical for behavior-change tools -Small posture corrections can have a significant long-term impact -Building AI-powered features in the browser requires careful performance optimization -Most importantly, we learned that awareness is the first step toward healthier habits.

What's next for PostureSense

PostureSense is currently Prototype 1. Planned future features include: -Personalized posture scoring -Daily posture analytics and history -Smart reminders and break suggestions -Gamification with streaks and achievements -Mobile device support -Accessibility modes for broader usability

Our long-term goal is to make PostureSense a daily companion for healthy sitting.

**PostureSense isn’t about forcing perfect posture. It’s about making users aware at the exact moment it matters.

Good posture starts with awareness. PostureSense delivers that in real time.**
