PROBLEM TO BE SOLVED: To provide an electrostimulation device and an electrostimulation system extremely rarely causing malfunction and capable of driving target fingers at high accuracy by clarifying correspondence between the movement of the fingers and electrodes in a short time without being affected by a state of being worn around a users arm or individual differences.SOLUTION: When a host updates an electrode probability matrix describing a Bayesian posterior probability as an element, the Bayesian posterior probability representing the movement of which finger an electrode corresponds to, the electrostimulation device compares a position of an element where the movement of a finger being present on a left upper part of the electrode probability matrix occurs and, if necessary, rearranges a column of the electrode probability matrix.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2019,JPO&INPIT【課題】ユーザーの腕に装着した状態や個人差に左右されず、短時間で手指の動きと電極との対応関係を明確にし、誤動作が極めて少なく、高い精度で目的の手指を駆動できる、電気刺激装置と、これを用いる電気刺激システムを提供する。【解決手段】電極がどの手指の動きに該当するのかを示すベイズ事後確率が要素として記述された電極確率行列をホストで更新する際、電極確率行列の左上に存在する手指の動きが生じた要素の位置を比較して、必要ならば電極確率行列の列を並べ替える。【選択図】図8
