Unfortunately there is no real "standards". There are usability laws in
some places like California, but those are in place to help people with
disabilities (blind, deaf, etc.). User interface design is something
that is highly debated and some companies commit many employees to work
That said, there are many great resources to learn UI best practices.
Google scholar ( http://www.yqcomputer.com/
) has many papers on the
subject. Here's one paper that is pretty good
). Joel Spolsky wrote a book
that is a very short read and covers most of the basics of UI design.
The name of the book is "User Interface Design for Programmers". He
also has many good essays on his website (www.joelonsoftware.com).
Another major authority on UI design is BJ Fogg
). One last person to read up on, Jakob Nielsen.
As I said, this is a subject you can almost debate forever. The best
thing to do is continue to test your UI. The only real standard that
matters is how other people (aka your users) feel about your interface.
Hope that helps, good luck!
