I spend a lot of my time thinking about UX and design, and I try to consciously think about it in the wild when I can. One of the things that always catches my eyes is the idea of discoverability, or how a user is able to discover that action X does some thing Y.
A basic way to do so is to rely on patterns that we’re all familiar with. For example, this link is blue, and if you hover over it with your mouse, you can see the cursor change. That is a helpful context clue, since you’ve probably seen and interacted with many links before, and because it has the same pattern, you can expect it to do the same thing.
Sometimes there are things that are new to you but are still intuitive when you first explore them, like using a touch screen for the first time. We touch things all the time, and when you first used a good touch screen, you were probably able to quickly understand how it worked. You moved your finger, the page scrolled, and that feedback helped you to quickly solidify the connection between your gestures and the screen’s actions. This is like discoverability through action, where you’re able to figure it out as you try it.
I also think about the category of things that aren’t intuitive and require some guidance, like Googling steps to show a cursor in an iOS screencast or putting together IKEA furniture. Woe is the fool who tries to discover a complicated IKEA piece through action! (Side note: there should be competitive IKEA furniture speed runs). This discoverability is aided by a guide, and although the quality of these guides can vary, sometimes it is helpful to first RTFM.
What iOS is doing these days
This brings us to a weird area: what about things that are unintuitive and unguided? Or, as I like to say, how the hell was I supposed to know it would do that?1
I’d like to present the following features for your consideration, with an exaggerated pointer to show the interactive actions:
Deleting a number on the iOS calculator
To delete the last digit from a number you entered in the iOS calculator, you can swipe the numbers to delete.
Using the spacebar as textbox navigation
To better navigate around a text document, you can long press the spacebar, then navigate around.
Switching between Safari pages by swiping the URL bar
To go back and forward in Safari, you can swipe the edges of the screen. To switch between tabs, you can swipe the URL bar left and right.
Going back after opening a new Safari tab
This is more of an unintuitive nitpick than a feature, but when you swipe back from a new tab, you silently close that tab and return to the old tab, unless you’ve already closed the old tab.
I don’t think any of these are intuitive or easily discoverable. You’ll sometimes see these features pop up in life hack or “I never knew this hidden feature existed” tweets, and that novelty and surprise is indicative of the lack of discoverability for these features. They’re at an odd intersection of 1) not following previous expected patterns, 2) not being intuitive, and 3) not being clearly explained anywhere, unless you happen to stumble upon them.
This is where you frequently see some cliché comments like “Steve Jobs would fire the people who made these”. Yeah maybe, but who am I to make that claim, much less to argue that it would be a good thing.
Good design for very complicated systems is hard, and these are just a few points where it fell short. It ends up being a double edged sword as well, because the complicated features (that must have taken many hours to build, debug, test, and launch) are hard to discover — how many users end up swiping their calculator or using the spacebar navigation? I’d love to see those metrics.
As much as I like to point out design shortcomings, it’s always funny to me to think about the number of very, very complicated things we take for granted now, with things only popping up as notable when they aren’t perfect. It’s like modern front ends — yes it’s complicated, but the expectations are very high as well. ↩︎
