VESTIBULAR ELECTRIC STIMULATION DEVICE AND CONTROL METHOD OF THE SAME

To provide a vestibular electric stimulation device which can reduce cutaneous pain applied to a user and can suppress reduction of pseudo acceleration sense.SOLUTION: A vestibular electric stimulation device comprises: first and second electrodes which apply electric stimulation to the vestibule of a user; an input part for accepting a target value of current applied to the first and second electrodes; and a control circuit for controlling the current applied to the first and second electrodes. The first electrode has N first sub electrodes in a first region on the head of the user. The second electrode has N second sub electrodes in a second region different from the first region. The control circuit controls a current value so that a total value of current values of the currents applied to the N first sub electrodes and the N second sub electrodes becomes the target value.SELECTED DRAWING: Figure 2 【課題】ユーザに与えられる皮膚痛覚を弱めつつ、疑似的な加速度感覚が小さくなってしまうことを抑制できる。【解決手段】前庭電気刺激装置は、ユーザの前庭に電気刺激を与える第１電極および第２電極と、第１電極および第２電極に印加する電流の目標値を受け付ける入力部と、第１電極および第２電極に印加する電流を制御する制御回路とを備える。第１電極は、ユーザの頭部の第１領域にＮ個の第１サブ電極を有する。第２電極は、第１領域と異なる第２領域にＮ個の第２サブ電極を有する。制御回路は、Ｎ組の第１サブ電極および第２サブ電極のそれぞれに印加される電流値の合計が目標値となるように電流値を制御する。【選択図】図２
