Citing work by Jakob Nielson, Rachel talks about transition duration and the user’s perceived experience given different delays and durations. For example, 100 milliseconds will appear instantaneous. On the other hand, an animation longer than 10 seconds can leave the user feeling disconnected. After sharing a few example, Rachel gives her recommendations for animation timing.
- Let's focus a little bit on duration.…So, back in 1993, Jakob Nielsen did a bunch of research…that showed that there were…three major time limits to keep in mind…when optimizing human-computer interactions,…specifically, page loads.…Now, it should be mentioned that humans…and their interactions with computers…have changed a lot since 1993.…We have people who are much more…used to using computers today…on faster internet connections…and even with gesture interfaces that respond…immediately to them, like in the app environment.…
So our expectations today might be different…from how they were in 1993.…However, these experiments haven't been repeated,…and they do give us some temporal guidelines to work from.…Not to mention, they do line up with some experiments I saw…in the past, and I'll talk about them in a moment.…So let's extrapolate a bit from this research.…What he found was that, at 100 milliseconds,…a jump cut, that is to say, going from one page to another,…if it takes 100 milliseconds,…will feel instantaneous to a user.…
