Spine v2.1.0

#Overview

This update introduces a high-performance gRPC-based sensor communication system, along with a 3D hand visualization and pose analysis system that greatly improves the user experience. In particular, professional export capabilities for external use of motion data have been enhanced.

---

#gRPC Sensor Communication

• gRPC Protocol Introduced: Added a Protobuf-based communication layer (IGrpcSensorService) to optimize data transfer efficiency
• High-Speed Streaming: Supports real-time streaming of full sensor data at 80 frames per second (80 FPS)
• Enhanced Security: Switched to an HTTPS certificate-based encrypted channel to ensure data security
• Developer Support: Provides a C# integration guide for connecting with other services

#Hand Visualization & Analysis

Hand data transmitted from the device can be visually monitored with precision through an OpenGL-based viewport.

#GL Viewport & Pose Analysis

• 3D Viewport: Visualizes left and right hand models using the Avalonia-based HandGlControl
• Visual Feedback: Displays spheres on fingertip joints (Tip) for intuitive tracking status
• Pose Analysis Engine:
  • Finger bend analysis via FingerBendAnalyzer
  • Real-time pose recognition using PoseMatcher and PoseDatabase
• Bottom UI Panel: Real-time display of bend status bars and recognized pose results
• Algorithm Improvement: Improved pose similarity detection accuracy

#System Requirements (Changes)

• A graphics environment supporting OpenGL 3.3 or higher is recommended
