Here's an interesting PDF
In a nutshell, iOS 6 was slightly less of a cognitive load because it was more familiar than iOS 7. However, because of the improvement of efficiencies in iOS 7 (like Control Center, and fixing multitasking), respondents were happier with iOS 7.
Thanks for that article, I never saw it before, it was a good read but also helps provide strength to some of my points.
Your statement above includes an apples-oranges example. First, control center and fixing multitasking could have been implemented in any OS, be it iOS 7’s flatter, vaguer OS or iOS 6’s “more obvious” OS. It’s rather unfair to reward iOS 7 for introducing certain high level interface improvements that could have been added to any maturing iOS.
Jumping down to the “Results by Platform” in that article, it’s the controversial aspects of iOS 7 that hurt it and were completely unnecessary. That article tends to brush off users’ “quibbles and controversies” over iOS 7" a bit too quickly, seemingly in an attempt to focus more on the benefits of new features introduced in iOS 7’s than the steps backwards in intuitive, efficient, obvious interface design. It’s those quibbles and controversies over the increased vagueness aspects of flat design & iOS 7 in general, plus the rather unnecessary complete revamping of all controls/icons across the board (seemingly for the sake of something new more than anything else) that penalizes iOS 7.
Rewarding iOS 7 for things like control center and multitasking is like putting two different cups on the table, filling only one with coffee, and then proclaiming the design of the first one as clearly better, and the design of the empty one as clearly worse.
I'm sure if one digs deeper you may find similar cases but the point is there wasn't a drop-off in usability going from iOS 6 to iOS 7.
Oh yeah? This article explains well my point, by focusing on the quibbles and controversies that the article you shared seemed to just brush off.
I understand this position. But we were already used to text buttons. Text buttons pre-date iPhone. The very website you're on has text buttons. Look at the MacRumors menu bar. Look at the footer.
There were text-as-buttons too with iOS6. Yet as a whole, the HIG for iOS 6 (beyond the stitched leather, brushed aluminum, and green felt) had much more obvious, intuitive, and efficient interface that lent text-as-buttons to "just work" much more intuitively.
iOS 7 seemed to start to use greyed-out text as "available" while, prior, greyed-out meant an unavailable command.
iOS 7 started using text-as-buttons a bit too broadly; I have yet to use a post-iOS 6 video streaming service or music player for which the teeny-tiny buttonless icons for play, rewind, pause, etc. don't often require 2-3 taps to get the command to work. Things were much better when those commands had larger button shape areas for a more secure, definite pressing.
Most of the world owns a smartphone. Having a little box around an 'Edit' text button at the top right corner (where it's been for over a decade) isn't going to 'improve' efficiency for anyone.
Also, how many people are pressing 'Edit' in any given app? Maybe once a day?
Does it need to be a prominent 'I'm-right-here-in-your-face!' button when you're spending most of your time using the content, not the OS UI?
Now come on, you picked one function that, sure, does not need to be at the forefront at all times. I’m talking about various apps that require a slide or swipe or tap to access a function one uses constantly in that app. For the sake of a “clean interface,” it takes more work than before. That’s the major failing with iOS 7 and beyond.
However you do bring up another issue I take with the post-iOS7 flat design. Now that everything is flat and borderless, most times when one holds their finger to pop up iOS's edit tools, the copy/cut/paste/etc tools having a white font on borderless black background too often blend into the surrounding screen (especially bad in dark mode). It takes extra time to sometimes recognize the desired tool that's hiding in plain sight amongst the background content.
It's those flat-design minimalist form-first cues that are the most painful. It's as if there's a fear of extra pixels.
There may be apps with garbage UIs like DirectTV's but there were always lots of apps with garbage UIs.
No, I noticed way fewer garbage apps (with garbage interfaces) before, because the pre-iOS 7 human interface guidelines lent themselves to providing more obvious, intuitive tools & indications to help designers keep on a good path. Or, I noticed many more awful-designed apps after iOS 7, as various designers having varying degrees of talent introduced apps within the new HIG’s that exacerbated the vagueness of the post-iOS 6 HIG…things like light blue font on white backgrounds, or apps full of lots of unused white space, the pushing of often-used tools offscreen, the eradication of different-colored zones for tools vs. content such that everything just blends together and takes more cognitive power to work thru, etc.
Have you used a modern iOS app? Or macOS? Most 'buttons' are icons these days.
Look at Mail, or Messages, or Safari, or heck even FCPX. Loads of icons. They don't need a little rectangle around them for most people to know what they are.
No, they don’t need a button shape, but you’re focusing on that way too much. Go find a screenshot of the OSX Mail app with Yosemite vs. Big Sur or vs. Monterey. I find the cognitive load to use Monterey’s Mail up to be much higher than it was with Yosemite — the icons or folders or mailboxes did not have button shapes but there was much more distinction between various areas of the app (mail boxes, message list, message preview, tools/menu) etc. and the buttonless icons were much more differentiated from each other, lending to quick, intuitive use.
Same for Finder. Compare a Yosemite Finder window to that of Big Sur or Monterey. There’s no comparison as to which has less eye strain and less cognitive load.
Anyway, we can argue about this for days but until you find a 'more' intuitive OS that's as powerful as iOS, and compare their usability studies, these are all just a matter of opinions and taste.
There are (were) more intuitive OS/iOS’s having less cognitive load overall. iOS 6 was more intuitive than anything after it, even if the iOS’s after it had introduced new welcomed features. OSX’s immediately before Yosemite offered a more intuitive design language.
If one can argue the issue of adding “too much,” such as the uber-skeumorphic felt, stitching, brushed metal (which is where we were at iOS 6 and before), then certainly there can be the issue of taking away too much, which was the main issue at iOS7/Yosemite times and many of which still lingers today. Luckily for all of us, Apple and others have slowly started reintroducing elements through the UIs that harken back to less-vague, less-flat interface cues. There’s still a way to go though.
