Notes For the present, gesture recognition algorithms based on the accelerometer have contradiction between dynamic real- time and recognition rate. Aiming at this problem, a probability matrix model of interval distribution and dynamic gesture recognition method is proposed. The gestural signal from the three dimension accelerometer is preprocessed through a series of methods includ- ing automatically action data detection algorithm, normalization, and cubic spline interpolation. Moreover, according to the eharaeter- istics on signal distribution, the observation points in each axis are determined and get the probability matrix of interval distribution on each observation point. Further, the on-line and fast gesture discrimination algorithm is realized on the optimized matrixes. The method is evaluated on real data set from a finger-mount wearable device. The result shows that it has good real time effect and high recognition rate.
