Re: Transitions causing motion sickness - WCAG failure and how to handle?

Karl,

I just remembered something that used to happen with me in the car when I was sighted. I could never read in a car for a long period of time. I would get motion sickness as well. Mind you that I can handle the rockiest boat on a lake or in the ocean without an issue. The only thing I know of that would give me motion sickness is being in a car and reading with my eyes, which I cannot do anymore.

I say that to second you on this one. I may if I could see get motion sickness from such a thing. What if I am in a car and I am looking at this site. Will the motion sickness double or cancel out? That would be something interesting to try. If you test it make sure someone else is driving or let us know so we can stay off the streets.

Thanks, everyone.

I'm going to sit with the designers and the brand team at the client and make some recommendations, including a tool to switch off transitions and animations (though this won't affect the YouTube videos they'll have).

I'm also going to start doing some deeper work on motion design to see what guidance can be given more widely to minimise (hopefully eliminate) the impact the transitions could have.

Thanks again :)
