The one I have personal experience with is this:

http://www.amazon.com/Human-Computer-Interaction-3rd-Alan-Di...

Which is not particularly well reviewed, but it is adequate, and you can apparently get the 2nd edition for $1.27 + shipping. It's major problem, as with most textbooks, is that's it's written in dry, overly qualified prose. But it should still be skimmable.

Honestly, these things are jam-packed with good, reliable information. I thought I knew a bunch after years of doing Donald Norman-esque analyses, but I still got a lot out of it. Just remember that it's less important to remember the theory than to have been exposed to it. It's enough just to have the concepts rattling around in your brain somewhere.

I did a course at University called Human Computer Interaction. Essentially it was the science of user interfaces. The course book of the same name by Dix, Finlay, Abowd and Beale (3rd edition) was really good. It contained a lot of accessible theory and plenty of heuristics too that you can implement straight away. Highly recommended.
