To continue an effect of wakefulness support.SOLUTION: A wakefulness support device of an embodiment comprises: a detection part for detecting a drowsiness level of a driver of a movable body; a determination part for determining whether or not wakefulness support for the driver is required, on the basis of the drowsiness level; a control part for applying vibration stimulation to the driver by vibrating a vibration application part which is provided on a seat where the driver is seated, when it is determined that the wakefulness support is required by the determination part. The control part vibrates the vibration application part on the basis of a vibration waveform formed into a shape in which a vibration waveform of a first frequency for promoting muscle tension and a vibration waveform of a second frequency for suppressing muscle tension, are superposed, in at least a partial time zone, when vibrating the vibration application part.SELECTED DRAWING: Figure 5
【課題】覚醒支援の効果を長続きさせる。【解決手段】実施形態にかかる覚醒支援装置は、移動体の運転者の眠気レベルを検出する検出部と、前記眠気レベルに基いて、前記運転者の覚醒支援が必要か否かを判定する判定部と、前記判定部によって前記覚醒支援が必要と判定された場合に、前記運転者が着座する座席に設けられた振動付与部を振動させることで前記運転者に振動刺激を付与する制御部と、を備える。前記制御部は、前記振動付与部を振動させる場合に、少なくとも一部の時間帯は、筋緊張を促進する第1の周波数による振動波形と、筋緊張を抑制する第2の周波数による振動波形と、を重畳した形の振動波形に基いて前記振動付与部を振動させる。【選択図】図5
