PROBLEM TO BE SOLVED: To provide a compact tactile sense presentation technique for making a fingertip generate tactual sensation without interposing a device between the fingertip and a tool (spatially transparent), without generating a feeling of strangeness on operations, and without obstructing a tool operation further.SOLUTION: A spatially transparent tactile sense presentation device includes: two stimulating electrodes abutted along each of two afferent nerves that run on both side faces of a finger one ground electrode abutted more on the palm side than the two stimulating electrodes and an electric signal generation part for giving predetermined electric signals for which at least one of a wave height and a frequency corresponding to respective stimulating electrode terminals is controlled, to the respective stimulating electrodes. An electric stimulation is generated in the two afferent nerves by giving the electric signals to the respective stimulating electrodes, and the tactile sensation is generated at the end position of the finger. A tool operation support system uses the spatially transparent tactile sense presentation device.COPYRIGHT: (C)2012,JPO&INPIT【課題】指先と道具の間にデバイスを介在させず(空間透明型)、また、操作上の違和感が発生せず、さらに、道具操作を阻害することもなく、指先に触覚を生成させるコンパクトな触覚提示技術を提供する。【解決手段】指の両側面を走る2本の求心性神経の各々に沿って当接される2個の刺激電極と、2個の刺激電極よりも掌側に当接される1個のアース電極と、刺激電極の各々に刺激電極端子の各々に対応する波高と周波数の少なくとも一方を制御した所定の電気信号を与える電気信号発生部とを有しており、刺激電極の各々に電気信号を与えることにより2本の求心性神経に電気刺激を発生させ、電気刺激により、指の末節位置に触覚を生じさせる空間透明型触覚提示装置。前記空間透明型触覚提示装置を用いている道具操作支援システム。【選択図】図1
