Study on head moving and tracking in virtual reality system

MA Deng-wu,YE Wen,LV Xiao-feng,DENG Jian-qiu (Department of Ordnance Science and Technology NAEI,Yantai 264001,China)  
In order to decrease visual delay in virtual reality,we studied and analyzed the testing results of all sorts of human being head motion.We put forward that the head moving of human being is a Guass-Markov stochastic process and constructed a stochastic mathematics model for head motion.We also proposed an effective algorithm for head-moving prediction based on Kalman filtering and preprocessing of the measured data.Theoretical analysis and simulation showed that this algorithm can improve the prediction precision,reduce the limitation to head motion,and decrease visual delay effectively.
