User Experience (UX)
User experience is about the user’s experience. Keep it simple whenever possible.
Different users experience different things. They have different perceptions.
Ahh, this is why companies have different UIs for different users to provide different UXs. Because different users have different needs.
“Design is not just what it looks lie and feels like. Design is how it works.” - Steve Jobs
It may look good, but if it is difficult to use, then there is no use.
I saw this in CS138, but you should be using the Principle of Least Astonishment.
