Usability Principles Collated by Source [#UX] and a Happy Christmas!

So, I’ve been working on my UX notes for the new unit, and as part of this I’ve been collating some principles. As it’s Christmas, I’m adding those for usability just in case they may be of interest.

Happy Christmas!You will notice in the table below that the left column describes the principle, guideline, or rule (these are sometimes used interchangeably between the different experts); while on the right side the experts are listed along with a footnote pointing to the text from which the principle is derived. In collating these principles I have not followed slavishly the nomenclature proposed by each author, but have instead placed them in categories which I believe have the same conceptual value even if the naming of that principle does not follow that in the source it is derived from.

Principle Appears in Source
