Thehumanwatching moving images displayed onawide-field display orscreen sometimes suffers fromthe visually-induced motion sickness (VIMS)that induces symptoms related totheautonomic nervous system suchasnausea, vomiting, anddizziness. Theprevious study indicated that themaximumcross-correlation coefficient (Pmax) between blood pressure andheart rate whosefrequency components arelimited totheneighborhood of0.1Hz isauseful index to evaluate theeffects oftheVIMSonhumans(1). Thepresent study hasproposed anewmethod forobtaining Pmaxwith measurement ofneither continuous blood pressure norECGbutusing onlyfinger photoplethysmography. Theadequacy oftheproposed method wasevaluated onthebasis ofcomparison withtheconventional method. Anexperiment inwhich multiple subjects weresimultaneously watching thesameswaying video imagewascarried out.Theexperimental result hasshownthat theproposed method worked successfully aswell astheconventional method.
