Motion Sickness Incidence System

Motion sickness on ships is an important issue for people prone to motion seasickness. The probability of the occurrence of motion sickness symptoms grows with increasing duration of motion exposure. WJEC's implementation of the MSI measurement system is based on ISO standard 2631-1, 1997, which relates passengers' acceleration exposure time and frequency.

Its components are:

  • Bridge display showing current MSI, predicted MSI, compartment MSI, and alarms.
  • Input data consists of readings of four triaxial sensor packages.
  • Programmable inputs are location of sensors and passenger compartments.
