We do this in cartoons as well. Check out this Spider-Verse animator breaking down a shot of Gwen drumming. [1] If you look at individual frames, there are all sorts of details that make no logical sense. In one frame, she actually has three hands! But it looks great if you see it in motion.

That is exactly what I'm talking about, though. This is not what is happening with buggy computer UI animations: these are not carefully crafted to look better in motion, they're actually only considered acceptable because it's kind of difficult to see the mistakes in the animation. Whereas cartoon animating, you could argue the details don't make logical sense, but that's only to someone who doesn't understand the p…

No one is defending outright buggy animations. OP is just saying the idea that every frame should make logical sense on its own ignores how animation actually works (and they're correct).

The cursor animation is actually a great one because it does not add any latency. By comparison, when animations are not disabled on my Pixel 6 it takes almost one second to switch application instead of maybe 100ms (double tapping the app swap button to get to the previous app running).

God yeah smartphones are the worst, Apple (& co) particularly. My iPhone 12 Mini could feel so much faster if I could just disable all the annoying animations that just make everything feel slower instead of being helpful. Setting animation speed to 0x is probably the feature from Android I miss the most.

An app with no animations at all is going to feel terrible. You can test this out yourself, if you have an Android you can set animation speed to 0x in the developer settings. It is jarring to see instant changes and it actually takes your brain a second to process what happened, and that process is probably slower than having the animation in the first place. I have mine at 0.5x and that feels sufficient, still fast…

An app with no animations feels awesome. It's great and it doesn't take my brain any time to process what happened since I already knew what was going to happen when I press the button that makes things happen on purpose.

Hardly any difference. If you haven't seen it before, try an Android phone in your hand and toggle animations 1x/0x and see what a stark difference it is. iOS is still littered with animations all over the place with that toggle enabled.

Indeed: one of the first things I do on a new android phone is activate developer mode specifically so that I can set the animation timescale to 0×.

Which the majority of people think is a horrible experience. There's even a sibling comment in this thread pointing that out: https://news.ycombinator.com/item?id=48518721

Unless you can back that up, "Majority" is something you're making up. It's a guess.

It also doesn't matter whether it's true if the majority or not- "Instant transitions are only good in theory" is not a true statement. Instant transitions are good in practice for many people and that has been true for decades.

The KDE start menu has always annoyed me (well, since whenever they switched from the Windows 95 inspired one to the XP or Vista inspired one) for this reason. When you switch views, the view switches immediately (which is good) but the indicator animates slowly from one state to the other.

The result is that the indicator is not really indicating what it's supposed to (since it's out of sync with the view): It's indicating the old view when I'm already in the new one, and then it's indicating something between the old and new views, when clearly I'm not between views at all. So it's completely wrong for the entire animation until it finishes.

I initially thought "Every Frame Perfect" meant a strict avoidance of any jank or stutter in motion, which I'm fully on-board for but as a film, video and 3D technologist, you're spot on calling out motion blur and similar temporal artifacts. In motion, they not only look 'most correct' to the human visual system, they are the most interpretable. Adding the correct blur to motion makes it appear clearer but seen as a…

Regarding your last point, I think it's almost always wrong to move something discontinuously, but I do think designers should think a lot more about getting out of the way of the user. A 50-100 ms animation is more than enough for most motions and keeps the UI feeling snappy. Also, animation should be decoupled from input wherever possible. I hate it when I have to sit there waiting for an animation to complete befo…

> waiting for an animation to complete before the app will start acknowledging my keystrokes.

Or you find out you can input as the animation happens, but when the animation finishes, you’ve lost where your input ended up and don’t know if you can backspace/delete and retype.

(Yes, I’m expressing multiple issues here w/ui & animation & input)

I'm sure a UI that had none of these imperfect frames would feel better, but now I really want someone to edit each of these clips to show what it would actually look like. At the same time, why does everything need motion? My understanding is that motion should be used if an action subtly changes the UI in a region that's different from where the action was triggered (e.g. toasts) I think many of these transitions a…

Play any game with good UI and you will see animations used everywhere. Instant transitions are only good in theory.

I stopped playing quite a few games because of gratuitous animations.
