The Reduce Motion option in iOS (Settings > General > Accessibility) helped many users for whom iOS’s animations and parallax effects cause motion sickness and nausea due to vestibular disorders. Writer Craig Grannell charges that Apple has not followed suit with OS X 10.11 El Capitan and tvOS, both of which sport the kind of eye candy that makes him ill. In OS X, the only app that attempts to help is Photos, which has a Reduce Motion option in its preferences, but Grannell claims that both it and tvOS’s Reduce Motion settings are almost entirely ineffective. Although it’s impossible to know what percent of the population suffers from vestibular disorders, estimates range from 5 to 35 percent, meaning that there could be many millions of people out there who endure some level of discomfort due to unnecessary animations and effects. We’d like to see Apple extend its accessibility work in iOS to its other operating systems (including watchOS, which Grannell doesn’t discuss).
