Laboratory studies of motion sickness
Experimental studies to investigate factors influencing motion sickness, including the direction, frequency and magnitude of translational oscillation, rotational oscillation, and Coriolis stimulation.
Influence of vision, posture, and individual characteristics on motion sickness.
Investigations of sickness and vection in stationary people caused by motion of the visual field.
Physiological responses to low frequency motions.
Field studies of motion sickness
Studies of motion causing sickness in sea vessels (ships, hovercraft, hydrofoil, oil rigs), in land transport (rail and road), and in aircraft. Studies of factors influencing sickness in sea, road, rail and air transport.
Development of methods of predicting motion sickness (e.g. motion sickness dose value).
Assessment of motions and shocks on boats, ships, oil rigs.
Postural stability
Experimental studies are conducted to investigate factors influencing postural stability, including the magnitude, direction, frequency and waveform of translational oscillatory motions. The dependence of postural stability on subject characteristics (i.e. age and weight) is also investigated.
The postural stability of standing and walking subjects perturbed by oscillatory motions is evaluated using both subjective and objective methods.
The outcomes of experimental studies are used to develop models to predict postural stability. These models can be used to optimize oscillatory motions and environmental factors (e.g. support) influencing postural stability in transport.
Experimental studies of postural stability also aim to understand the mechanisms involved in human postural control.
