VYTA — Your Body. Your Rhythm. 🌿
What if your camera could help you become more aware of your breathing rhythm?
That's the idea behind VYTA, a human-sensing experience I'm building for the Presage SmartSpectra SDK Challenge.
VYTA explores how real-time camera-based physiological signals can become a more intuitive and engaging experience through an adaptive breathing visualization.
💡 The idea
Rather than presenting raw measurements and numbers, VYTA aims to transform human-sensing data into a visual experience that encourages users to slow down, observe their breathing patterns, and become more aware of their natural rhythm.
Its central concept is the Adaptive Breathing Canvas — a visualization designed to respond to genuine measurements from the SmartSpectra SDK.
🛠️ What's under the hood?
I'm building VYTA using:
- Electron — desktop application framework.
- JavaScript — application logic.
- Presage SmartSpectra Node SDK — real-time camera-based human sensing.
- Chart.js — measurement visualization.
One of the most challenging parts so far has been camera reliability.
The SDK requires a sufficiently consistent frame rate, so I investigated camera constraints, exposure settings, frame delivery, and stream lifecycle management. I was able to achieve approximately 29 FPS in testing, although intermittent camera reliability issues are still being addressed.
I'm also working through the real measurement pipeline, including SDK validation states, protobuf decoding, and the integration of breathing measurements into the interface.
🔍 What I'm focusing on next
- Reliable camera initialization and cleanup.
- Validating genuine breathing measurements with a real user session.
- Building the Adaptive Breathing Canvas.
- Creating meaningful session summaries.
- Keeping privacy and user consent central to the experience.
🔐 Privacy matters
VYTA is designed around explicit camera permission and transparent sensing. Measurements should never be presented as medical diagnoses or treatment recommendations. The goal is awareness and interaction, not medical decision-making.
🚀 Building in public
This project has been a great opportunity to explore the practical challenges of real-time human sensing — especially the gap between getting a camera feed and building a reliable experience on top of it.
I'm looking forward to sharing the next milestones as VYTA develops.
