The introduction of fake zooms, parallax, sliding and other changes in Apple's new iPhone and iPad software has a very real effect on people with vestibular disorders 
 
 Apple's new mobile operating system for the iPhone and iPad, iOS 7, is stark and minimal, yet dynamic. It makes frequent use of zoom and slide animations; the home screen boasts parallax, with icons apparently floating above subtly animating wallpaper. And it's making people sick. 
 
 Triggers and symptoms vary, but TidePool mobile app developer Jenni Leder's experience is not uncommon. A self-professed power-user, she frequently switches apps; but on iOS 7, this has caused headaches and feelings associated with motion sickness. "I now have to close my eyes or cover the screen during transitions, which is ridiculous," she told The Guardian, adding that there's nowhere to hide: "It's not apps that affect me, but accessing them. Tap a folder and the view zooms in. Tap an app and it's like flying through the icon and landing in that app's micro world — and I'm getting dizzy on the journey there." 
 
 This wasn't the case under iOS 6. That system wasn't devoid of triggers (full-screen slide transitions being fairly common), but zooming was minimal and parallax was absent, as were gamified animation effects such as subtly shifting and sliding balloons in Messages. 
 
 The same minimal effect is true of stock Android and Windows Phone, which lack triggering animations and effects as dynamic and aggressive as those in iOS 7. 
 
 Jump up 
 
 The severity of the jump from iOS 6 to iOS 7 means some organisations dealing with such motion-sickness problems are recommending that people with such conditions don't upgrade their iOS devices. A number of affected users have reportedly switched iPhones that had already been upgraded to iOS 7 for models running iOS 6. 
 
 Reactions to screen-based systems — especially those utilising 3D effects — aren't new. Cynthia Ryan, executive director of the Vestibular Disorders Association, says 3D effects can cause "intense nausea, dizziness and vertigo", sometimes from general vision problems, but also from visual-vestibular conflict. She added symptoms "manifest more severely if a viewer already has a disorder of the vestibular system". 
 
 The vestibular system is what gives us our sense of balance and sense of spatial awareness; it's dependent on three mutually orthogonal fluid-filled canals in the inner ear. But when the vestibular system and visual system come into conflict, the effect can be distressing. 
 
 John Golding, professor of applied psychology at the University of Westminster, says visually-induced motion-sickness often arises from "the induction of perceived self-motion while at the same time the vestibular system and somatosensory systems signal that the body is in fact static". 
 
 The number affected is hard to pin down. Golding says that "visually induced motion sickness" has "affected a relatively small proportion" - less than 5% - of the population, compared with other stimuli such as from boats (sea sickness), cars/coaches (car sickness), etc. But prevalence may be much higher in some clinical grpoups with vestibular disease." 
 
 Ryan says: "These symptoms manifest even more severely if a viewer already has a disorder of the vestibular system. An estimated 69 million US adults aged 40 and over — 35% of all Americans — experience vestibular system dysfunction." 
 
 Dizzying change 
 
 Similar symptoms can also arise from neurological conditions that cause central dizziness. Matt Gemmell, an independent iOS developer, thought it made sense that those with such conditions "would find some parts of the new iOS 7 interface uncomfortable or disorienting," because it "makes more extensive use of animations — and those animations are more pronounced". 
 
 The problem for those suffering is twofold: first, many other people refuse to believe a problem exists; secondly, there's no fix. "We're often contacted by people affected by moving images on screens, but people are affected in different ways — what's a problem for one person may not be for another," explained Natasha Harrington-Benton, director of the Ménière's Society, a UK charity for peopel with disorders causing dizziness or balance disorders. "But these disorders can be extremely debilitating, despite there being no visible symptoms". 
 
 Marissa Christina, a podcaster and writer about hidden disabilities, suggests there was a "lack of awareness" about such issues: "The words 'dizziness' and 'vertigo' don't strike fear into people, but those living with severe cases are in ongoing angst awaiting the next unwarranted attack". 
 
 The lack of a solution is the bigger problem. Apple provides a "Reduce Motion" option within the iOS 7 Settings app, but it is poorly labelled; it merely disables the parallax effect, but doesn't stop zooming or sliding. Apple did not respond to requests for comment for this article. Which for now, leaves affected people on their own. 
 
 Golding's suggestions to those affected include to "rest often", avoid situations which reduce peripheral visual clues which give the correct information the person is static (in other words, don't hold your iPad to your nose), or "just not use the device". Those might suit some, but aren't practical if you're reliant on mobile devices. 
 
 Blind spot 
 
 What's surprising is Apple's apparent blind spot regarding balance and related concerns. Gemmell said: "Apple is more committed to accessibility than any other platform provider I know of." This is borne out by the software's otherwise plentiful aids for people with vision, hearing and motor-control issues. 
 
 However, technology writer Kirk McElhearn quesions whether Apple is ignoring people with vision and balance problems. He told the Guardian: "If Apple wants to truly cater to users with disabilities, it must look more closely at which features cause difficulties, make more effort to listen to users who find them hard to use, and enable them to be more comfortable". 
 
 Christina said Apple should start by acknowledging the issue and "initiating an open dialog with those affected, developers, and Apple's own accessibility team". The company must, she said, "narrow in on what's adversely affecting people and ensure features can be disabled". 
 
 Gemmell says he is "sure suitable options to more comprehensively disable motion will be forthcoming". In the meantime, he recommended those affected send an email to accessibility@apple.com, succinctly stating which animations are problematic and requesting the means to disable them. 
 
 Playing a part 
 
 In the meantime, developers can also do their part. With app creators often following Apple's lead, it's perhaps inevitable the short-term will see yet more animation in iOS 7. Gemmell urges developers to "consider all categories and ability levels of user, and design interfaces judiciously"; they should enable users to disable anything that "could be annoying or intrusive", and UI effects should "have a useful function, such as showing context, hinting about functionality, or demonstrating transition, rather than being purely decorative". 
 
 With the latest update to the popular calculator app PCalc, developer James Thomson has recognised the accessibility concerns, and provided the option to "remove full-screen transitions throughout the app". 
 
 But he says= he'd sooner see Apple add this at system level, :so individual developers don't have to". Gemmell hopes Apple and developers alike would react accordingly regarding animations and transitions, simply because it's the right thing to do: "Accessibility affects everyone, and devices should be usable in all situations, by as many people as possible. Designing for accessibility levels the playing field, and increases the utility of devices for everybody." ||||| A major change in Apple’s iOS 7 update was its sleek, minimal aesthetic; however, the amount of motion now found within is anything but minimal. 
 
 The screen zooms in and out as folders and apps are open and closed; the app switcher zooms and slides; full-screen slide transitions are commonplace; and a faux-3D parallax effect exists on home screens, with icons appearing to float and move independently of background wallpaper. 
 
 For many people (most of Stuff included), this might seem dynamic and exciting. But iOS users with motion-sickness have suddenly found their iPhones and iPads are causing them problems. 
 
 On his blog, The Tech Chat, Mark Coppock wrote that “iOS 7 makes me sick — literally�?, and thought the new animations were “all more aggressive�? than in iOS 6. 
 
 The net result: “It feels to me like the whole screen is moving, and it generates a sort of motion sickness. I feel dizzy and can feel the very beginnings of nausea kicking in.�?
– Some Apple users are sick of the company's new iOS 7 operating system. Literally. The new zoom and slide animations, and the 'floating" icons on the home screen, are causing motion sickness in many people with vestibular disorders—conditions that affect balance and vision, the Guardian reports. "I now have to close my eyes or cover the screen during transitions, which is ridiculous," says one app developer, who reports headaches and other symptoms associed with motion sickness. "Tap an app and it's like flying through the icon and landing in that app's micro world—and I'm getting dizzy on the journey there." Other symptoms from exposure to this kind of animation can include "intense nausea, dizziness and vertigo," says a spokesperson for the Vestibular Disorders Association. One developer affected by motion sickness has already built an app to disable the offending features, reports Stuff. But others say Apple itself needs to step up. Tech writer Kirk McElhearn says Apple was once "at the forefront of providing accessibility options," but now needs to demonstrate more sensitivity to users like him. "Their apparent disregard is disturbing, and shows a trend toward paying lip service to accessibility, but not thinking it through," he writes on his blog Kirkville.
