In addition to audio and video, bidirectional vibrotactile interaction enables highly immersive communication. However, there is a concern of howling due to signal loopback caused by coupling vibration sensors and actuators. To solve this problem, we propose to apply the ISM(Intensity Segment Modulation), which can modulate the frequency while maintaining the tactile sensation of vibration, to suppress the positive feedback by modulating the vibration frequency. We verified our method by using a bilateral tactile interaction device that transmits vibrations to the other party based on sensed vibrations. We confirmed that while the unprocessed transmission of the measured vibration caused signal feedback and loopback, the proposed method clearly suppressed them.
