The source provides an extensive technical overview of Amazon’s proprietary augmented reality (AR) glasses, codenamed Amelia, which were introduced to optimize "last mile" logistics and delivery workflows. These lightweight, purpose-built glasses feature a monochrome green heads-up display (HUD) to project essential information directly into the driver's view, thereby increasing safety and eliminating distraction from handheld devices. The system’s functionality is powered by a custom Delivery AI model and advanced computer vision, which handles real-time package scanning, accurate AR navigation, and predictive hazard detection like spotting loose pets. To maintain wearability, complex processing is managed by a detachable "compute puck" worn on the driver's vest, minimizing lag through edge computing. Initial pilot testing has demonstrated that this technology can boost delivery efficiency by up to 20%, representing a significant evolution in wearable technology integrated within Amazon’s interconnected AI ecosystem.
