They don't cure my kids' or wife's car sickness, unfortunately. I'm not sure the implementation is as good as it could be. It seems a bit rough.
Motion sickness is an overlooked problem. A large percentage of the population has severe, almost debilitating motion sickness. It curtails a ton of travel. Almost all transportation and tourism related businesses would stand to benefit hugely from a real cure, not to mention VR and even regular gaming to some degree. There ought to be an industry effort to fund research.
OTOH, motion sickness is often called "car sickness" for a reason, people who suffer from it only sometimes suffer on a bus, and rarely if ever on a train or a plane, so I'm not sure I would agree that "all transportation and tourism related businesses" are impacted. Also, doesn't dimenhydrinate work for your wife or kids?
Dimenhydrinate has undesirable side effects. My wife cannot ride buses and gets sick on planes too. It restricts our travel quite a bit.
It's not a 'cure' for me either but it does allow me to do quick short tasks on the phone if necessary and then I can get back to focusing on the horizon.
It'd be interesting to gather some actual statistics. I can't look at a screen for more than a minute as a passenger without starting to feel a twinge in my gut.
If you're looking for non drowsy options, I've found ginger capsules to be very effective as an anti nausea treatment.
Supposedly 1/3 of people are "highly susceptible".
And of those, how many does this help, and how much? Like does this mean I could look at a map application while my wife drives for a few minutes and be ok? Or does it help a lot of people be able to read for a long time?
In my family, Apple's implementation helps only a small amount if at all. I'd also love to see some real statistics. What I think is really missing is coverage of peripheral vision, so maybe a similar feature built into AR glasses could be a real solution.
