🔥 InnerFire — Spatial Journaling for Snap Spectacles

InnerFire is a real-time XR journaling experience where users create logs through mindful breathing, reflection, and voice journaling, which fuel a persistent, interactive flame. The flame adapts and evolves across sessions, encouraging repeat use and emotional reflection.

🛠 System Overview

InnerFire was built for Snap Spectacles (5th Edition, 2024) using Lens Studio v5.9.1, with all functionality running entirely on-device. Gesture tracking, voice input, spatial anchoring, and state persistence are handled natively.

Core Features

• Gesture-based interaction using the Spectacles Interaction Kit, with Interactable components mapped to log selection
• Voice journaling activated through anchored interaction; recordings are session-scoped and locally managed
• Camera-relative flame anchoring, with Snap’s tracking system and depth estimation for spatial consistency
• Persistent local state, using Lens Studio’s internal storage API to track engagement and evolve flame behavior

👥 Contributors

InnerFire was concepted and designed collaboratively by Sai Saran Grandhe, David Madey, Shawn Smith, Anastasia Sotiropoulos, and Victor Chen as part of team Neon Panda Pack.

All technical implementation was led and executed by Victor Chen, including:

• Implemented world-anchored flame placement using tracked surfaces and spatial logic
• Designed and built interaction UI with camera-relative layout and gesture triggers
• Developed gesture-based log creation via the Spectacles Interaction Kit
• Integrated microphone input for session-based voice journaling
• Enabled persistent local storage to track flame state across sessions
