+
+## 🛠️ 技术栈选择
+
+### 后端技术栈选择方案
+
+#### 方案A: 纯JavaScript/Node.js (推荐)
+- **优势**: 与现有Glass代码完全兼容，无需额外运行时
+- **翻译API**: Google Translate API, DeepL API, Azure Translator
+- **NLP处理**: compromise.js, natural.js
+- **图形处理**: D3.js, vis.js
+
+#### 方案B: Python微服务
+- **优势**: 更强大的NLP库支持
+- **技术栈**: FastAPI + spaCy + NLTK + transformers
+- **通信**: HTTP API或IPC通信
+- **缺点**: 需要额外的Python运行时
+
+#### 方案C: 混合架构
+- **核心**: JavaScript保持与Glass集成
+- **NLP处理**: Python微服务处理复杂NLP任务
+- **通信**: WebSocket实时通信
+
+### 前端UI技术栈
+- **框架**: React + TypeScript (与现有一致)
+- **样式**: Tailwind CSS (与现有一致)
+- **图表库**: D3.js + React-D3-Graph
+- **动画**: Framer Motion
+- **状态管理**: React Context + useReducer
+
+### 数据存储扩展
+```sql
+-- 新增数据表结构
+CREATE TABLE translations (
+    id INTEGER PRIMARY KEY,
+    session_id TEXT,
+    source_text TEXT,
+    target_text TEXT,

+```
+
+### 交互设计
+1. **实时同步**: 所有四个面板实时更新
+2. **关键词点击**: 点击关键词显示定义
+3. **思维导图交互**: 拖拽、缩放、展开/折叠
+4. **语言切换**: 快速切换翻译语言对
+5. **导出功能**: 支持导出思维导图、术语表
+
+## 🔌 集成策略
+
+### 与现有Glass系统集成
+1. **无侵入式集成**: 通过事件系统集成，不修改核心STT流程
+2. **配置驱动**: 通过配置文件控制新功能开关
+3. **渐进式启用**: 支持单独启用/禁用各个增强功能
+4. **向后兼容**: 确保不影响原有功能
+
+### 事件集成点
+```javascript
+// 在现有 listenService.js 中添加事件发射
+handleTranscriptionComplete(speaker, text) {
+    // 原有逻辑
+    this.sendToRenderer('transcription-update', { speaker, text });
+    
+    // 新增：触发增强功能
+    if (this.enhancedFeaturesEnabled) {
+        this.eventBridge.emit('enhanced:transcription', {
+            speaker,
+            text,
+            timestamp: Date.now(),
+            sessionId: this.currentSessionId
+        });
+    }
+}
+```
+
+## 📈 性能优化策略
+
+### 实时性保障
+1. **并行处理**: 翻译、关键词提取、结构分析并行执行
+2. **增量更新**: 只处理新增的文本片段
+3. **智能缓存**: 多层缓存策略减少重复计算
+4. **异步处理**: 非阻塞的后台处理
+
+### 内存管理
+1. **滑动窗口**: 只保持最近的对话内容在内存中
+2. **懒加载**: 按需加载历史数据
+3. **垃圾回收**: 定期清理过期缓存
+
+### 网络优化
+1. **批量翻译**: 合并短文本片段批量翻译
+2. **本地优先**: 优先使用本地NLP处理
+3. **降级策略**: API失败时的备用方案

+
+### Native Messaging 配置
+
+#### 主程序端Native Host配置
+```json

+  "path": "/Applications/Glass.app/Contents/MacOS/native-host",
+  "type": "stdio",
+  "allowed_origins": [
+    "chrome-extension://YOUR_EXTENSION_ID/"
+  ]
+}
+```
+
+#### 通信协议设计
+```javascript
+// 消息格式规范
+const MessageTypes = {
+    // 从扩展到主程序
+    WEB_CONTENT: 'webContent',        // 网页内容数据
+    HIGHLIGHT_REQUEST: 'highlight',    // 高亮请求

+    KEYWORDS: 'keywords',             // 关键词列表
+    DEFINITIONS: 'definitions',        // 术语定义
+    HIGHLIGHT_DATA: 'highlightData'   // 高亮数据
+};
+```
+
+### 网页学习场景优化
+
+#### 1. 在线课程支持
+- 视频平台检测（YouTube, Coursera, edX等）
+- 字幕提取和同步
+- 课程进度跟踪
+- 笔记关联功能
+
+#### 2. 文档阅读优化
+- PDF在线阅读器支持
+- 学术论文结构识别
+- 参考文献自动提取
+- 阅读进度保存
+
+#### 3. 多语言学习场景
+- 自动语言检测
+- 实时翻译显示覆盖
+- 生词本功能
+- 语言学习进度追踪
+
+## 🔗 扩展与主程序集成
+
+### 数据同步策略
+```javascript
+// 在现有 listenService.js 中添加Web扩展支持
+handleWebContent(webData) {
+    // 原有音频处理逻辑
+    this.sendToRenderer('transcription-update', audioData);
+    
+    // 新增：处理Web内容
+    if (this.enhancedFeaturesEnabled && webData) {
+        this.eventBridge.emit('enhanced:webContent', {
+            content: webData.text,
+            url: webData.url,
+            timestamp: Date.now(),
+            sessionId: this.currentSessionId
+        });
+    }
+}
+```
+
+### 统一的增强功能触发
+```javascript
+// 统一处理音频和Web内容
+onContentUpdate(source, data) {
+    // source: 'audio' | 'web'
+    // 并行触发所有增强功能
+    this.emit('translation:process', data);
+    this.emit('keywords:extract', data);
+    this.emit('glossary:analyze', data);
+    this.emit('mindmap:update', data);
+    
+    // Web特定处理
+    if (source === 'web') {
+        this.emit('webextension:highlight', data);
+    }
+}
+```
+
+此架构设计确保了新功能的高度模块化、可扩展性和与现有系统的无缝集成，同时新增的Chrome浏览器扩展功能为网页学习场景提供了强大的支持。

+# Glass视频学习功能使用指南
+
+## 概述
+
+Glass的视频学习功能是一个强大的屏幕内容分析工具，能够自动捕获屏幕内容，进行OCR文字识别，并提供实时翻译、关键词提取和术语解释功能，特别适用于在线课程、视频教程和文档阅读。
+
+## 功能特点
+
+### 🎥 智能屏幕捕获
+- **自动帧提取**: 智能分析屏幕变化，只处理有意义的帧
+- **多屏幕支持**: 支持选择不同的显示器进行捕获
+- **性能优化**: 可配置的捕获频率和质量级别
+
+### 🔍 高精度OCR识别
+- **多引擎支持**: Mock引擎（演示）、Tesseract.js、原生引擎
+- **多语言识别**: 支持英文、中文等多种语言
+- **智能预处理**: 图像增强和噪声过滤
+
+### 🎞️ 智能帧分析
+- **相似性检测**: 自动跳过重复或相似的帧
+- **文本区域识别**: 智能判断帧中是否包含有价值的文本
+- **稳定性分析**: 确保只处理稳定的视频帧
+
+### 🔗 无缝集成
+- **增强服务集成**: 与翻译、关键词提取、思维导图完全集成
+- **实时处理**: OCR结果自动传递给增强功能进行处理
+- **统一界面**: 在Glass主界面查看所有增强功能结果
+
+## 使用方法
+
+### 1. 启动视频学习
+
+在Glass监听界面中：
+1. 点击视频学习控制按钮（📹图标）
+2. 展开视频学习控制面板
+3. 点击"Start"按钮开始屏幕捕获
+4. 系统会自动选择主屏幕开始捕获
+
+### 2. 配置选项
+
+可通过代码配置以下选项：
+```javascript
+const options = {
+    captureRate: 0.5,        // 捕获频率（每2秒一帧）
+    qualityLevel: 'medium',  // 质量级别：low/medium/high
+    ocrEnabled: true,        // 是否启用OCR
+    languages: ['eng', 'chi_sim'], // OCR语言
+    autoStart: false         // 是否自动启动
+};
+```
+
+### 3. 监控状态
+
+- **绿色指示灯**: 视频学习正在运行
+- **红色指示灯**: 视频学习已停止
+- **状态文本**: 显示当前服务状态
+
+### 4. 手动捕获
+
+在视频学习运行时，可以点击"Capture"按钮手动捕获当前帧进行OCR处理。
+
+## 技术架构
+
+### 核心服务
+
+```
+VideoLearningService (主服务)
+├── ScreenCaptureService (屏幕捕获)
+├── OCRService (文字识别) 
+├── FrameAnalyzer (帧分析)
+└── Enhanced Integration (增强集成)
+```
+
+### 数据流
+
+```
+屏幕内容 → 帧捕获 → 智能分析 → OCR识别 → 增强处理 → UI显示
+```
+
+### 集成点
+
+- **EnhancedService**: 统一的增强功能入口
+- **ListenService**: 与现有Glass功能集成
+- **UI Components**: ListenView中的视频控制界面
+- **IPC Communication**: 前后端通信
+
+## API接口
+
+### IPC通道
+
+```javascript
+// 启动/停止视频学习
+window.api.invoke('video:start-learning', options)
+window.api.invoke('video:stop-learning')
+window.api.invoke('video:toggle-learning')
+
+// 状态和统计
+window.api.invoke('video:get-status')
+window.api.invoke('video:get-stats')
+window.api.invoke('video:get-screens')
+
+// 手动捕获
+window.api.invoke('video:capture-frame')
+```
+
+### 事件监听
+
+```javascript
+// UI事件监听
+window.api.listenView.onVideoSessionStarted(callback)
+window.api.listenView.onVideoSessionStopped(callback)
+window.api.listenView.onVideoLearningUpdate(callback)
+window.api.listenView.onVideoError(callback)
+```
+
+## 配置说明
+
+### 视频捕获配置
+
+```javascript
+// 在VideoLearningService中
+this.config = {
+    enabled: false,
+    captureRate: 0.5,        // 每2秒捕获一帧
+    ocrEnabled: true,
+    autoStart: false,
+    qualityLevel: 'medium',  // low/medium/high
+    languages: ['eng', 'chi_sim']
+};
+```
+
+### OCR引擎配置
+
+```javascript
+// 在OCRService中
+this.config = {
+    languages: ['eng', 'chi_sim'],
+    confidence: 60,          // 最低置信度阈值
+    preprocessing: true,     // 图像预处理
+    caching: true           // 结果缓存
+};
+```
+
+### 帧分析配置
+
+```javascript
+// 在FrameAnalyzer中
+this.config = {
+    differenceThreshold: 0.15,  // 帧差异阈值
+    minTextLength: 20,          // 最小有效文本长度
+    stabilityFrames: 3,         // 稳定性检查帧数
+    skipSimilarFrames: true     // 跳过相似帧
+};
+```
+
+## 性能优化
+
+### 1. 捕获频率优化
+- 降低捕获频率可减少CPU使用
+- 推荐频率：0.2-1.0 FPS
+
+### 2. 质量级别选择
+- **Low**: 640x480，适合文本识别
+- **Medium**: 1280x720，平衡性能和质量
+- **High**: 1920x1080，最高质量
+
+### 3. 智能跳帧
+- 自动跳过相似或无文本的帧
+- 减少不必要的OCR处理
+
+### 4. 缓存机制
+- OCR结果缓存，避免重复处理
+- 智能缓存清理策略
+
+## 故障排除
+
+### 常见问题
+
+1. **屏幕捕获失败**
+   - 检查屏幕录制权限
+   - 确保在Electron环境中运行
+
+2. **OCR识别率低**
+   - 调整图像质量级别
+   - 检查文本对比度
+   - 尝试不同的OCR引擎
+
+3. **性能问题**
+   - 降低捕获频率
+   - 减少质量级别
+   - 启用智能跳帧
+
+### 调试信息
+
+启用调试模式查看详细日志：
+```javascript
+console.log(videoLearningService.getStatus());
+console.log(videoLearningService.getPerformanceStats());
+```
+
+## 扩展开发
+
+### 添加新OCR引擎
+
+1. 在`src/features/video-learning/ocr/engines/`创建新引擎
+2. 实现标准OCR接口
+3. 在OCRService中注册引擎
+
+### 自定义帧分析算法
+
+1. 继承FrameAnalyzer类
+2. 重写分析方法
+3. 在VideoLearningService中使用
+
+### 添加新的集成点
+
+1. 监听`video:text_ready`事件
+2. 实现自定义处理逻辑
+3. 通过EnhancedService发送结果
+
+## 最佳实践
+
+1. **合理设置捕获频率**: 根据内容变化频率调整
+2. **启用智能分析**: 让系统自动优化处理
+3. **监控性能指标**: 定期检查统计信息
+4. **配置合适的语言**: 根据内容选择OCR语言
+5. **测试不同场景**: 在各种内容下测试效果
+
+## 更新历史
+
+- **v1.0.0**: 初始版本，基础屏幕捕获和OCR功能
+- **v1.1.0**: 添加智能帧分析和性能优化
+- **v1.2.0**: 完整的增强服务集成
+- **v1.3.0**: UI控制界面和用户体验优化
