Researchers at the University of Michigan are developing a wearable system that will help travellers in self-driving cars avoid motion sickness.
The solution, which works by co-ordinating lights to match the movement and speed of the autonomous vehicle, will combat the potential for nausea by helping the user's brains remain in sync with their eyes, even when remaining stationary.

The patent indicates that the wearable would be able to mimic the lateral movement, vertical movement, velocity, acceleration, yaw rate, roll rate, and pitch rate of the vehicle, meaning the lights "or other visual stimuli" would be akin to staring out a window to avoid sickness.
So, for example, if you were reading a book or looking down at your phone for the duration of your journey, the system (which researchers also indicate could be built into the car itself) of lights would nullify the usual effects.
The patent doesn't go into great detail about how exactly the lights would work, but it's fair to assume they would subtly mirror the direction the car would be travelling in order to keep your eyes and brain in check.
Of course, we're not yet at the point where this is an issue, since autonomous vehicles are still a couple of years away from wider rollouts, but the concept will be able to be applied to any kind of self-driving car when the time comes.
It's also dependent on whether the wearable itself sees eventual production, which is no guarantee when it comes to patented technology, but the team of researchers are currently looking for potential commercial partners to get the device into production, so stay tuned.
