We started exploring a simple question:

That led us into remote photoplethysmography (rPPG) estimating heart rate using subtle pixel variations from the face captured through a webcam/camera.

From there, we started thinking:

What if physiology wasn’t just shown as numbers… but experienced spatially?

So we built CardioVerse an XR concept where:

• heart rate drives a reactive environment
• emotions influence colors and atmosphere
• blood flow and hormones become visual elements
• AR overlays can show physiological state
• VR mode turns the body into a navigable “digital twin”

Some scenarios we explored:

• XR glasses in a meeting room showing calm/stress states (consent-based)
• immersive VR “inside the body” visualization
• phone-based AR self-analysis using camera input only

Current stack:

• rPPG (CHROM / POS methods)
• OpenCV + signal processing
• Three.js / WebXR
• real-time BPM streaming via WebSocket

Would genuinely love feedback on:

• the product direction
• technical realism
• XR interaction ideas
• ethical/privacy considerations
• possible healthcare / wellness use cases
