Turn on your WAVELETECH band, then open FocuX. The app will guide you through a step-by-step Bluetooth connection flow. Connection typically takes 2-3 seconds.
确保手环已开机，打开 FocuX 后跟随引导页完成蓝牙连接。
Stamina (0-100) represents your body's current capacity for focused work. It's computed from three EMG dimensions: Consistency (motor control stability), Tension (involuntary muscle contraction), and Fatigue (neuromuscular exhaustion via MDF spectral shift).
Stamina 是从 EMG 三维指标实时计算的体能续航值，反映你当前的专注工作能力。
The app will launch and display the interface, but real-time EMG data requires a WAVELETECH band (BLE) or a desktop EMG server (WiFi). Without a data source, Stamina tracking is unavailable.
App 可以正常启动，但需要手环或桌面 EMG 服务器才能接收实时数据。
FocuX uses Apple Foundation Models to generate personalized daily coaching summaries based on your EMG session data. The AI analyzes your work patterns, fatigue levels, and provides actionable recommendations.
FocuX 使用 Apple Foundation Models 基于你的每日 EMG 数据生成个性化教练总结和建议。
No. All AI processing runs entirely on your iPhone using Apple Foundation Models. Zero data is sent to any server, cloud API, or third-party AI service. When Foundation Models is unavailable, the app falls back to a built-in rule engine — still fully offline.
不会。所有 AI 推理都在 iPhone 本地完成。不可用时自动降级为内置规则引擎，始终离线。
AI Coach requires iOS 26+ with Apple Foundation Models support (iPhone 16 and later). On older devices, FocuX automatically uses the built-in rule engine for coaching summaries — same functionality, just template-based instead of generative.
需要 iOS 26+ 和 Apple Foundation Models（iPhone 16 及以上）。旧设备自动使用规则引擎生成教练总结。
All data is stored exclusively on your iPhone in a local SwiftData database. FocuX has zero cloud infrastructure — no servers, no analytics, no third-party services. Uninstalling the app permanently deletes everything.
所有数据仅存储在 iPhone 本地 SwiftData 数据库中。没有云端，没有服务器。
Swipe left on any session in the History view to delete it individually. Uninstalling the app removes all local data. There is no cloud data to worry about.
在历史记录页面左滑删除单条会话。卸载 App 清除全部数据。
Long-press on your home screen, tap the "+" button in the top-left, search for "FocuX". Choose from 4 widget types: Session Count (small), Stamina (small), Weekly Trend (medium), or Dashboard (large).
长按主屏幕 → 点左上角「+」→ 搜索「FocuX」→ 选择小/中/大组件添加。提供会话计数、续航值、周趋势、综合面板四种样式。
89% overall accuracy across 6 gesture classes, with per-gesture F1 scores ranging from 0.89 to 0.91. End-to-end latency is under 85ms (P50). The system maintains 87%+ accuracy even after 8 hours of continuous use.
6 类手势整体准确率 89%，端到端延迟 < 85ms，连续使用 8 小时后仍保持 87% 以上。
A quick personalization process: 30 seconds of rest + 30 seconds of light grip. This establishes your personal EMG baseline and improves accuracy by 15-20%. You only need to do it once.
30 秒静息 + 30 秒轻握，建立个人肌电基线，准确率提升 15-20%。只需做一次。
