In view of shortcomings of the existing dynamic hand gesture recognition
a dynamic hand gesture recognition algorithm based on Kinect device is proposed. The hand area is got through Kinect and detect the number of fingers
numbers of the left and right hand fingers is used as start and end of dynamic hand gesture.Motion trajectory of the hand is analyzed
aiming at movement direction change of movement track
and extract change-of-direction angles of dynamic gesture as feature. Use hidden Markov model( HMM) train and recognize each gesture. Experimental result proves that using this method can recognize 16 capital hand-writen English letters
