Research on Improved Somatosensory Simulation Algorithm Based on VR Motion Simulator

Aiming at the problem that the classical somatosensory simulation control algorithm used in VR (Virtual Reality) motion simulator has the shortcomings of phase delay and false hint, which leads to insufficient consistency of virtual and real motion and causes VR motion sickness, an improved somatosensory simulation algorithm is proposed. The improved somatosensory simulation algorithm adds vestibular perception system on the basis of classical simulation algorithm, feeds back the output error of the algorithm, uses fuzzy control algorithm to correct and predict the input acceleration and angular velocity, and simulates the topographic fluctuation in virtual reality. The improved somatosensory simulation algorithm is modeled and simulated in MATLAB/Simulink. The simulation results show that the improved somatosensory simulation algorithm reduces the phase delay and false hints, and improves the consistency of virtual and real motion. (paper)
