Micro-interactions are contained moments that revolve around a single use case. Micro-interactions focus on detail — they do one thing but they do it well!
“The difference between a product you love and one that you tolerate are often micro-interaction you have with it”
— Dan Saffer
Micro-interactions typically get very little attention and are designed to be invisible. They allow users to focus on some parts of the UI and provide feedback to the user.
One important aspect of good UX design is paying attention to the smaller details. This is because sometimes the smaller details might be overlooked but they can cause many pesky problems.
“If micro-interactions are poor, the main features, no matter how nicely done, are surrounded by pain and frustration”
— Dan Saffer
Micro-interactions should always have a purpose and embody the brand voice.
