在AE制作人机交互UI动画，在PS中完成平面设计，然后在AE完成动画。

In this screencast tutorial we’re going to prototype an app UI animation. We’ll take a Photoshop layout, then bring it to life using Adobe After Effects.

Prototyping interfaces with After Effects is a great way of exploring complex animations, either for your own experiments or presenting to a client. It’s a very popular approach these days, and a quick search on Dribbble will reveal loads of UI animation examples, many of which have been made with After Effects.
