Begun our discussion about moving from user definition and exploratory research into who our users are, and into consideration of how and why our users need the things they do, behave the way they do, and think the way they do. There are a broad range of methods and perspectives related to arriving at these understandings depending on your particular context, the goals you have in mind and the type of designs you are producing. However, all of them begin with one thing: understanding and working with the existing knowledge and contexts of human users.

Additionally, critique the way in which it is done, discuss how these decisions provided potential benefits and limitations in terms of usability and comprehension, design of the artifact, the range of interactions, and any related usability and design concepts you may find appropriate. For each, I want a paper that represents usage and understanding of some of the core HCD/usability/design concepts.
