DOCUMENTATION: DRAGON EYE – NEURAL-LINKED HMI SYSTEM
Project Overview
Dragon Eye is a high-stakes Vehicle Human-Machine Interface (HMI) built entirely within the Rive engine. It simulates a biological-mechanical bridge between a pilot and a dragon-class flight engine. This project represents 80+ hours of architectural engineering, focusing on real-time data flow, safety-critical overrides, and immersive visual feedback.
TECHNICAL ARCHITECTURE
1. The Logic Layer (Lua Scripting)
The system is powered by a custom-coded backend using 3 Node Scripts and 2 Listener Action Scripts. This setup handles:
Asynchronous Telemetry: Real-time calculation of velocity, altitude, and energy consumption.
Contextual AI Feed: A "Synaptic Feed" that pushes dynamic messages to the HUD based on the current flight state.
2. ViewModel & Data Flow
Utilizing a ViewModel architecture, the project ensures a single source of truth for all UI elements.
Range Map Converters: Translate raw user drag-gestures into precise engine-velocity increments.
Synchronized State Machine: Ensures seamless transitions between Idle, Cruise, Turbo, and Combat modes.
SAFETY-CRITICAL PROTOCOLS (The "Guardian" Logic)
To elevate the HMI from a visual tool to a survival system, I implemented two major safety overrides:
Automatic Structural Protection (Speed Limiter):
The system continuously monitors mechanical stress. If the pilot exceeds the structural safety threshold (550+ units), the Neural Override triggers an immediate, automated deceleration to prevent catastrophic airframe failure.
Atmospheric Reclamation (Oxygen Protocol):
The AI monitors the rider’s biological vitals. If oxygen levels drop below 15% due to high-altitude flight, the system initiates a forced descent to a "breathable zone" (lower altitude) to prevent pilot hypoxia, overriding manual controls until vitals stabilize.
VISUAL & COMBAT SYSTEMS
Weaponry Interface: Custom-coded weapon systems featuring synchronized flicker effects and dynamic target-locking scaling.
Adaptive HUD: The interface scales and shifts based on G-force simulation, providing a 1:1 responsive experience.
Audio-Visual Synergy: Designed to sync with high-tempo, adrenaline-driven soundscapes for maximum pilot immersion.
