Dragon Eye: 4K Neural-Link HMI (Rive) Description: High-performance Vehicle HMI with adaptive AI telemetry. Built in Rive using complex Lua scripting, 3 custom Node Scripts, and ViewModel architecture. Features automated structural safety speed-limiters and oxygen-depletion altitude overrides. Engineering meets survival. 🐉🚀 https://vimeo.com/1178627971?share=copy&fl=sv&fe=ci 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.
