Animation is a tricky topic when it comes to design, bringing up a lot of questions around quality, quantity and when to even consider using it.
The use of animation can be subtle, it can be brash, but it should always be necessary.
Throwing in animation for the sake of it will damage the experience your user has, whilst conversely, using it with skill will build a deeper, more human relationship with your product.
Well-designed animations make the experience feel crafted. In a human-centered design approach, where the user is the prime focus, animation actually creates a feeling of well-being once it’s discovered by users. As a designer, recognizing the invisibility of animations is just as important as designing them. Because you have to create something that feels human and accomplishes a task.
