In recent years, studies and applications of virtual reality (VR) have been actively conducted. Many of the studies on force sense presentation of VR sports are large-scale devices, and reproduction of shock is not strictly performed. In this paper, we focus on sense presentation of tennis and propose miniaturization of devices and waveform reproduction by genetic algorithm. In order to generate an impact on the racket, we mount a push solenoid in the racket, thereby making the force sense presentation device smaller. Moreover, by using genetic algorithm, we optimize the pushing timing of the push solenoid and reproduce the shock waveform. As a result, it was confirmed that the generated waveform approximates the impact waveform when the tennis ball was dropped into the racket.
