چکیده
|
In this exploratory study, we examined self-reports of physical discomfort among automobile passengers while being driven on an urban road. eight adults participated as passengers in an automobile driven by a professional driver on a predetermined course through city traffic. passengers were driven individually along the route. while underway, participants used a handheld device to indicate momentary feelings of discomfort arising from discrete vehicle motions. we continuously recorded vehicle motion in three axes of linear acceleration and 3 axes of angular velocity. we examined vehicle acceleration during the 3 s preceding each subjective response. we found that the maximum absolute acceleration required to elicit subjective discomfort was lower when vehicle acceleration changed sign (from + to −, or vice versa) than when acceleration was of a constant sign. in addition, participants’ reports of discomfort during the experiment were unrelated to their prior self-reports of generalized susceptibility to motion sickness. the results suggest that our method is valid, and has the potential to offer new insights into motion sickness causality.
