Inspiration

I saw a video demonstrating "remote controlled people" using GVS to modify a person's perception of balance when I was 7 years old. I've always wanted to try this project out. We could experience the sensation of movement in VR! Imagine being in a VR skydiving simulation and being able to feel the g-forces change in your head and feel like you're actually in 0 gravity.

What it does

Uses a technique called Galvanic Vestibular Stimulation to alter the perception of balance in the vestibular system in your ears. Allows the user to experience the sensation of falling to the left and right. By sending a steady ~3mA current to the mastoid processes in the skull, we can set the vestibular system to perceive falling toward the anode of the setup!

How I built it

We researched GVS techniques and bought our own cheap hardware. Made jacketed ribon wire and electrostimulation pads

Challenges I ran into

We didn't have any formal hardware, made it all ourselves! Oculus SDK1 firmware is not compatible with laptops sans dedicated GPUs

Accomplishments that I'm proud of

We can get people to experience the sensation of leaning even while they're completely stationary and sitting down. I can't believe it actually works!

What I learned

BioHacks are hard to experimentally set up. Everyone responds to a test system in a slightly different way.

What's next for BalanceVR

Getting real electrode pads and other hardware.
