A bit of background: I'm an 18 year old junior in college studying a dual major in computer science and computer engineering. I can figure out any concept regarding technology whether it be closures in functional programming or understanding advanced cryptography concepts. Despite this, I can't seem to be able to objectively look at a user interface I've created and judge its quality; it always seems 'good enough' for me as I know where everything is in it.<p>What are some resources I could look at regarding design of user interfaces? I understand the people that might use a product I create will not see it the same way that I do; they won't have the same expertise and familiarity with it at first site. My goal is to be able to create intuitive interfaces (the best UI is no UI[0]) that most people are able to use without issues and without the dreaded "where do I click to perform this action that I absolutely KNOW should be here?".<p>[0] - http://www.cooper.com/journal/2012/08/the-best-interface-is-no-interface
