Researchers look into keeping autonomous vehicles from becoming mobile vomitoriums
If you’re like me, and I’m just going to assume most of you are, motion sickness is a serious consideration on any car trip where you’re not driving. So what are we supposed to do in self-driving vehicles? Researchers are finally looking into this question with an experiment designed to see just what makes people like us so sick.
(Update: Yes, yes, vomitoriums aren’t a real thing! But there isn’t a better word for it.)
The study, at the University of Michigan, was undertaken because the researchers realized that if millions of people can’t read or do work in autonomous vehicles, that massively reduces the draw of using them in the first place. And it turns out there has been almost no investigation of why certain people get motion sickness in this context, what makes it better or worse, and so on.
“Very few studies have been conducted in cars; instead, a lot of the work has been done for sea and air transportation modes, performed in driving simulators or on motion platforms,” explained lead investigator for the project, Monica Jones, in a university news release. “A lot of scales that exist in the literature are based on nausea. If we design to a vomiting response, we have really missed the mark on autonomous vehicles.”
Basically the cars should be designed around making people actually comfortable, not stopping just short of losing their lunch. What does that even consist of? That’s what these initial experiments are meant to explore.
The team collected 52 people from a variety of demographics and had them sit in the car while it navigated the university’s Mcity Test Facility, a sort of mock urban environment meant for exactly this kind of work. The drive involved the usual turns, stops and accelerations you would experience being driven around a city, and participants were asked to perform some basic tasks on an iPad and answer questions posed by a researcher in the car. I can tell you I’m feeling queasy just thinking about taking part.
