Take advantages of six-axis sensor in gesture recognition and attitude recognition and the convenience of wireless system

a wireless crawling action recognition system based on six-axis sensor is designed to achieve crawling action recognition and attitude estimation. Determine the crawling intention by using dynamic time warping（ DTW） algorithm to match template and to recognize limbs gesture so as to determine crawing

and according to six-axis sensor data to estimate the attitude so as to determine the crawling direction. Experiments show that the probability of identifying the correct instruction within 3 s is 74. 2 %

and the probability of identifying the instruction is 91. 7 % within 4 s

which can meet the actual demand.
