環境適応型振動提示の主観評価―ツール質量差が触覚体験に及ぼす影響

抄録

This study evaluates the feasibility of an Environment-Adaptive Vibrotactile Transformation (EAVT) method, which identifies a tool’s transfer function and predicts vibrations for tools made of different materials or masses. We used acceleration data recorded with an ABS resin probe as the reference and attempted to estimate the recorded accelerations of heavier probes made of iron or equipped with a vibrotactile actuator. We assessed both the frequency spectra and subjective similarity of the predicted vibrations. The results indicate that while EAVT can partially account for amplitude changes due to additional mass, spectral mismatches remain problematic, leading to lower subjective similarity.
