Perceiving conflicting physical and visual motion cues can cause
symptoms of motion sickness (MS). However, etiology of MS is
still not known. ISO IWA3 (2005) reported that fundamental
research to discover the mechanism leading to visually induced
MS is much needed. Currently, both Commission Internationale
del’Eclairage (CIE/TC1-67) and ISO (ISO/TC159/SC4/SG) are
drafting standards concerning visually induced MS.
This study, funded by the Hong Kong Research Grants Council,
will apply and extend a cross-over frequency (COF) theory
previously proposed for motion sickness to explain and predict
human responses to conflicting low-frequency motion. The range
of motion frequency also overlaps with the range of motion in
tall buildings. Results of the research can predict occupant
discomfort in tall building under strong weather conditions.
The research will take place at the
simulator located at the CLP Power Wind/Wave Tunnel Facility (WWTF)
at HKUST. The PI of the project is Professor Richard So who is a
leading expert in motion sickness and ergonomics. He is the
Fellow of the Institute of
Ergonomics and Human Factors and
Commission Internationale de L'eclairage (CIE) Technical
Committee TC1-67. A Co-I of the project is Professor Kenny
Kwok from the University of Western Sydney, Australia. He is a
leading expert in wind-induced tall building vibration.
