GALVANIC VESTIBULAR STIMULATION DEVICE, CONTROL SYSTEM HAVING GALVANIC VESTIBULAR STIMULATION DEVICE, AND CONTROL METHOD

To provide a galvanic vestibular stimulation device that can give users a pseudo acceleration in a sensation close to an actual acceleration sensation.SOLUTION: A device comprises: a first electrode (E1) and a second electrode (E2) for applying a current to a vestibule of a user (Ur1); an input unit (140) for receiving a target value of the current between the first electrode (E1) and the second electrode (E2); and a control circuit (110) for applying the current corresponding to the target value received by the input unit (140) to the first electrode (E1) and the second electrode (E2). The control circuit (110) changes a current value over a first period (Dr1) from when application of the current corresponding to the target value begins, causing the current value between the first electrode (E1) and the second electrode (E2) to reach the target value, and changes the current value over a second period (Dr2) from a state in which the current value between the first electrode (E1) and the second electrode (E2) has reached the target value, thereby stopping the application of the current corresponding to the target value, wherein the second period (Dr2) is longer than the first period (Dr1).SELECTED DRAWING: Figure 4 【課題】実際の加速度感覚に近い感覚の疑似加速度をユーザに与えることが可能な前庭電気刺激装置を提供することである。【解決手段】ユーザ（Ｕｒ１）の前庭に電流を印加する第１電極（Ｅ１）および第２電極（Ｅ２）と、第１電極（Ｅ１）と第２電極（Ｅ２）との間の電流の目標値を受け付ける入力部（１４０）と、入力部（１４０）が受け付けた目標値に応じた電流を第１電極（Ｅ１）および第２電極（Ｅ２）に印加する制御回路（１１０）とを備え、制御回路（１１０）は、目標値に応じた電流の印加を開始したときから第１期間（Ｄｒ１）に亘って電流値を変化させて、第１電極（Ｅ１）と第２電極（Ｅ２）との間の電流値を目標値に到達させ、第１電極（Ｅ１）と第２電極（Ｅ２）との間の電流値が目標値に到達した状態から第２期間（Ｄｒ２）に亘って電流値を変化させて、目標値に応じた電流の印加を停止し、第２期間（Ｄｒ２）は、第１期間（Ｄｒ１）よりも長い期間である。【選択図】図４
