Difference between UI and UX
One of the challenges that I have found is communicating the fact that UI is not the same as UX and is just a subset of of UX as a whole .The general argument is that we create nice icons and layouts and decide on effective color codes and hence it makes it easier for users to use the application,hence this is UX work but when you bring up the concept of iterative low fidelity prototyping or usability testing ,I just get blank looks.
How do you communicate something like this ?
