Some thoughts: I realize these concepts could be new. Hopefully these explanations are helpful, but if you have any further questions or would like to discuss further, feel free to contact me.
	What is Human Computer Interaction? One definition calls HCI "the study of how humans interact with computers, and how to design computer systems that are easy, quick and productive for humans to use." But that's only the beginning. HCI lives in the space between design, technology, and human psychology. It's about applying our understanding of people to design interfaces and experiences. Simply, I believe technology is a tool - the application of science to do something for us. For me, humans are at the center, and the technology is used to support us. It isn't about forcing people to try to adapt to machines but redesigning the technology fit human lives. My goal is to help people and businesses see the benefits of having technology work for them. Eventually we won't see technology in terms of what it can do, but in terms of what it can do for us, and I will be a part of making that happen. What is User-Centered Design? Changing the way we understand technology means changing the way we develop it as well. Since it is no longer only about what is possible but also about what is usable, we must involve the users at every step of development. The Waterfall Model of software development just doesn't work anymore. Before spending the money and resources that go into development, we must test, and continue testing, our initial prototypes on users. User-centered design is an iterative process that involves prototyping, testing the prototype on users, and fixing our mistakes. Changes made to wire-frames are light years easier and cheaper to fix than problems found in the stages before development. For this reason, we start with a paper-pencil prototypes and build up the system, testing at every step of the way.
