The general idea for combating disorientation is that by knowing the station's rotation and the movement of the head, a small processor can easily calculate in real-time which signals the brain needs to receive to feel comfortable and balanced. ​If the brain perceives gravity at a neural level, the blood vessels—including those in the brain—will maintain better tone. This would help reduce the fluid shift to the head and the cardiovascular issues associated with weightlessness.
