The design of intelligent mobile phone action recognition system is researched, the control algorithm design of lin?ear feedback is taken, improve the sensitivity of mobile phone of action recognition and accuracy. Traditional intelligent mo?bile action recognition control algorithm using dimensional space motion planning sub, proposes a weighted minimum norm generalized inverse RRT algorithm, proposed a linear smartphone action recognition system improved feedback control algo?rithm, but there is recognition of the control accuracy is not high on the smartphone action, control delay larger problems. Therefore, this paper puts forward a linear intelligent mobile action recognition system improved feedback control algo?rithm, has constructed the action recognition system model of smart phones, the equation of motion of constructing smart phone action recognition system. Then the linear control strategy, improve the stability of the intelligent mobile action recog?nition and the accuracy of the closed-loop system, the construction of action recognition of smart phones. In the foundation of the algorithm, software compiling, applications in the application layer running Android, the implementation of the result?ing action recognition on smart phone control. The simulation results show that the action recognition system for smart phone design has high control precision, strong anti-interference ability, good stability, high control accuracy, can accurate?ly track the changes of action, to avoid delay in control and error control.
