Apple makes its operating systems accessible to people with a wide variety of physical limitations, but its tendency to rely on visual trickery like faux 3D effects has caused problems for users with vestibular processing problems. Technology journalist Craig Grannell has been talking about this for a while, most recently in a new blog post.
Grannell talks about the hoops he has to jump through to get OS X working to his satisfaction now that El Capitan has incorporated System Integrity Protection (SIP), a new security feature.
Recently Kirk McElhearn took up the mantle on is own site.
I do not, thankfully, have the same problems Grannell does with motion effects in iOS actually causing physical discomfort, but I do find it utterly unnecessary and superfluous, and shut it off when I can.
McElhearn echoes some complaints I’ve had in recent years as my vision has begun to falter. I’m having more and more problems accessing content and devices not only because of stuff that Apple is doing but because of stuff that Apple developers are — and aren’t — doing.
The entire Apple/iOS developer community needs to pay more attention to these issues; we’re not all 25-year olds with excellent vision.
