VR Dental Procedure Practice Simulator – IT & Computer Engineering Guide
1. Project Overview
The VR Dental Procedure Practice Simulator is a virtual reality-based training solution designed for dental students and professionals to practice common dental procedures in a realistic 3D environment. The system provides simulations of tools, patient interactions, and procedural feedback for skill enhancement without the need for live subjects.
2. System Architecture Overview
- VR Engine: Manages scene rendering and user interaction
- Dental Tool Simulation: Virtual representation of drills, mirrors, etc.
- Haptic Feedback Integration: (Optional) Tactile response for realism
- Procedure Logic: Governs steps for each dental task
- Assessment Engine: Tracks and evaluates performance
- Backend & Admin Dashboard: For data storage, reporting, and control
