Abstract:
Objective To design a virtual reality(VR) system for fracture reduction training using manikin technology.Methods The real-time posture information of the manikin skeleton was acquired by the inertial measurement unit(IMU).3DMAX was used to construct a 3-dimensional human skeleton model based on the human skeleton CT.The model was driven by the received sensor data and displayed the instant attitude.The skeletal attitudes and operation information were displayed in real time through the Visual Studio platform,which was displayed on the screen facing the trainee.Thus,a VA combination interactive training system was constructed.Results and Conclusion A set of simulated fracture reduction training system with high accuracy,low cost and VR combination was designed.Compared with the high-cost,precision optical instrument,the root mean square error (RMSE) of the fraction angle calculation was 0.595° in the static state,and was 1.609° in the dynamic state.This system can provide effective information for training operations and provide a new interactive platform for fracture reduction training.
