Description
Sion Cha and Wooksung Kim model the inner ear's balance sensors when the head spins off-center. Most studies assume the rotation axis passes through the canals' center, yet daily motion rarely obliges. Testing a real offset is hard because the canal's sensing membrane is too soft to mimic well in physical mock-ups.
The pair instead built a computer model coupling fluid and structure inside the canals, then ran step and waving motions through it. As the offset grew, the sensor's gain rose while its slow response constant shrank. That drift exposes blind spots in the simple filter models engineers use today. The authors offer a corrected transfer formula that carries the offset, aimed at virtual reality and motion-sickness work.
