Windows 11 時鐘 App 加入 AI 走神偵測

🔑 增強重點摘要

• •The feature leverages the Windows 'Focus Sessions' framework, which integrates with Microsoft To Do and Spotify to manage task lists and ambient audio alongside the new NPU-based attention tracking.
• •Privacy is managed via local NPU processing, ensuring that video feed data used for attention detection is never transmitted to the cloud or stored permanently by the Clock app.
• •This update is part of a broader 'Windows Intelligence' initiative, which aims to standardize NPU-accelerated background tasks across native Windows 11 inbox applications to reduce CPU overhead.

🛠️ 技術深入

• •Utilizes the Windows Copilot Runtime API to interface directly with the NPU (Neural Processing Unit) for real-time computer vision inference.
• •Employs a lightweight, quantized gaze-estimation model optimized for low-power background execution, minimizing impact on battery life.
• •Implements a 'Privacy-First' architecture where the camera stream is processed in a secure enclave, outputting only binary 'distraction' signals to the application layer.
• •The UI redesign utilizes the WinUI 3 framework, leveraging Mica material effects for improved performance and visual consistency with the Windows 11 design language.
