VR Simulation for Surgery Training – IT & Computer Engineering Guide
1. Project Overview
The VR Simulation for Surgery Training project is a high-fidelity virtual reality platform designed to help medical students and professionals practice surgical procedures in a risk-free, immersive environment. It simulates real-world surgical techniques, tools, and patient responses to enhance precision and reduce training errors.
2. System Architecture Overview
- VR Engine: Renders surgical environments and tools.
- Interaction System: Detects instrument handling and user hand movement.
- Haptic Feedback Integration: (Optional) Provides tactile response.
- Assessment Engine: Tracks performance metrics and procedural accuracy.
- Cloud Backend: Stores user progress, modules, and analytics.
- Admin Dashboard: Manages users, tracks usage, and updates scenarios.
