Galvanic Vestibular Stimulation

 

Galvanic Vestibular Stimulation (GVS)

for Enhanced Training and Immersion

 

Galvanic Vestibular Stimulation (GVS) is the application of low-level current to the inner ear, via electrodes placed on the head. By stimulating the inner ear can make someone feel like they are moving even when they aren’t.

We often focus on improving the machine in order to boost overall human-machine performance. But our GVS work aims to directly augment the human by targeting the vestibular system, a primary sensory system that impacts performance in most motion-based tasks: flying, driving, balance, agility, etc.

 

Simulator

Enhance Simulator Training by Adding Motion Cues

Increases fidelity and immersion while remaining low cost and portable. Decreases simulator sickness and enables simulation of extreme motions while safely on the ground.

 

Perception

Decrease Perception of Motion During Real-world Movements

Use “equal and opposite” GVS to decrease actual motion perceptions to minimize counterproductive or distracting motion cues and maximize performance across a variety of operational domains.

 

Sensorimotor

Enhanced Sensorimotor Training and Retention

Applying noisy GVS (nGVS) quickens learning of challenging physical mobility tasks. When the nGVS is removed, improved performance is maintained.

 

Applications

Potential Future Applications of GVS

  • Training and operations in sim and while inmoving environments
  • Mitigation of unwanted illusions from centrifuge and motion-based flight training regimens
  • Human space flight analog, post-flight vestibular disorientation mitigation
  • Commercial travel, autonomous car market
