Introduction To Usability

The principle of usability is integral to Human-Computer Interaction, yet it is one that is often misunderstood.  This section is intended as a brief introduction to what is meant by usability as well as ways in which a usable system can be developed.   This section is described as only an introduction to Usability because the whole course is about usability but the other sections refer to it in a more indirect fashion.
