Recently, many researchers have developed tactile displays using vibrotactile stimuli. However, a tactile display method stimulating multiple positions on the body especially for representing realistic experiences have not been studied enough. This paper proposes a tactile display method for conveying realistic hitting sensations of tennis with vibrotactile stimuli to the multiple positions of forearm. At first, we reproduce vibrotactile stimuli based on the measurement data for forehand strokes. Then, we investigate the effects of stimulus parameters, which are mainly focused on a damping ratio and a stimulus onset asynchrony (SOA), to represent the stroke sensation. Experimental results showed strong sensations were obtained when the damping ratio became small, i.e., duration of vibration became long. We also confirmed that SOA didn't have a great effect on hitting sensations in this experimental conditions.
