UX design includes fields from visual and sound design to human-computer interaction to information architecture. Very little of the user experience is just passive consumption.
For example, most Internet users are continually clicking, typing, switching between windows, and opening documents and applications. All of these require interacting with hardware and software, mostly without thinking.
Even when listening to music or watching videos, users are not entirely passive. They may be plotting their next move, scanning the user interface to make the whole experience as cohesive as possible, even when their aims seem unconnected. Therefore, a designer must accommodate these constant shifts in intention and provide the necessary features for smooth and straightforward interactions and transitions.
One cannot design a user experience, only design for user experience. You can’t build in the emotions you want your user to feel. All you as the designer can do is try to encourage some responses and distract from others.
