Description Sentinel is an AR cycling eyewear platform for road cyclists that extends situational awareness through a sensing and shared-data display system. It integrates rear-road detection, hazard mapping, and directional alerts into a unified augmented layer that preserves forward vision while expanding perceptual range.
A rear-mounted radar detects vehicles up to 100 feet and nearby cyclists within 10 meters, translating motion into proximity cues. An embedded microcontroller fuses sensor input with networked hazard data and renders outputs through a 128x32 OLED and reflective HUD film for peripheral visualization.
A distributed rider network enables geo-tagging of road hazards, creating an updating environmental layer. Information is filtered and customized through a companion app based on rider preference and context to reduce cognitive load.
A modular magnetic mounting system enables helmet or frame integration with repeatable alignment. Sentinel operates as a perceptual augmentation system combining real-time sensing and shared network intelligence to extend awareness and improve response time in dynamic road conditions.
Innovation Sentinel is an AR cycling eyewear system and the only product on the market purpose-built for real-time cycling safety augmentation. While most smart eyewear focuses on AI capture, recording, or audio interaction, Sentinel prioritizes live environmental awareness and in-ride hazard response.
The system addresses a core limitation in existing AR eyewear: optical legibility at close eye range. Sentinel uses a reflective HUD film and spatial projection approach that shifts information away from the lens plane, improving readability in motion and reducing distortion or eye strain. This enables usable AR visualization in cycling conditions that current devices do not support.
A rear-mounted radar, real-time hazard network, and directional alert system deliver live safety-critical feedback directly into the rider’s field of view. Unlike general-purpose wearables, Sentinel prioritizes real-time hazard response and continuous situational awareness in dynamic cycling environments.
By combining cycling-specific sensing, spatial display techniques, and shared rider intelligence, Sentinel defines a new category of safety-first AR cycling eyewear.
Product Detail Sentinel is a high-performance AR ecosystem designed to improve the safety and awareness of avid road cyclists. Constructed primarily from TPU, the flexible frames conform to various helmet geometries, while a magnetic attachment system ensures a universal fit over prescription or sun eyewear.
The all-in-one visor serves as a consolidated hardware hub, housing a rear-facing radar, a high-contrast OLED screen, and a peripheral LED strip for directional hazard cues. This configuration delivers information to riders on a need-to-know basis without breaking their line of sight or cognitive flow.
Engineered for endurance, the body weighs under 350g, allowing for comfortable, prolonged use during full-day rides.
Equipped with Bluetooth, Sentinel syncs with Strava and existing bike sensors. Our native app allows users to customize the OLED interface, prioritizing the most pressing stats for a tailored, distraction-free performance experience.
