Discrimination Threshold of Tactility to ERP-Modulated Vibration

摘要

We present tactile sensor figure information using modulated vibration produced from high band component f{sub}H (from 40 to 1000Hz) and low band component f{sub}L (from 2 to 40Hz). Vibration is modulated in 8 directions and we determine whether we could differentiate the direction in which it moves, focusing on presentation time, repetition presentation, and the interval between presentation stimuli. We found that presentation that repeats vibration continuously is most effective.
