""By changing the direction of the current, it can make me fall in that direction," she explains."
""I found the experience unnerving and exhausting: I sought to step straig"
Alternative controller designs continue to expand into unconventional interfaces that change how players interact physically with games. A streamer harnessed galvanic vestibular stimulation (GVS) to send DC current through the head to stimulate the vestibular nerve and intentionally destabilize balance. Changing current direction produced directional leaning and controlled veering while a handler manipulated a joystick. The setup simulated G-forces during a racing session and produced visible swaying and reports of flashing lights. The underlying GVS technique predates this experiment, with prior journalistic tests describing the experience as unnerving and exhausting.
