OPERATION INPUT SYSTEM

To provide an operation input system allowing an operator to perform input operation accurately by a finger.SOLUTION: An operation input system according to the present invention includes: a first sensor device which has an annular base body being wearable to a first finger of an operator, and outputs a first signal according to a motion of the first finger; a second sensor device which has an annular base body being wearable to a second finger different from the first finger and outputs a second signal according to a motion of the second finger; and a control device which determines a relative finger motion of the first finger and the second finger on the basis of the first signal and the second signal.SELECTED DRAWING: Figure 1 【課題】操作者が指動作による入力操作を高精度で行える操作入力システムを提供する。【解決手段】本発明に係る操作入力システムは、操作者の第１指に装着可能な環状の基体を有し、前記第１指の動きに応じた第１信号を出力する第１センサ装置と、前記第１指とは異なる第２指に装着可能な環状の基体を有し、前記第２指の動きに応じた第２信号を出力する第２センサ装置と、前記第１信号及び前記第２信号に基づいて、前記第１指及び前記第２指の相対的な指動作を判定する制御装置と、を備える。【選択図】図１
