ABSTRACT:
An anti-motion sickness mechanism comprises a platform suspended from a conveyance for movement about all principal axes. Any vertical movement of from 0 to 0.5 Hz has a tendency to cause motion sickness. A supplementary vertical movement of about 2.5 Hz is added to the platform to break up such vertical movement into sub-movements having a reduced tendency to cause motion sickness.
