HCIHuman-Computer InteractionWhat is it? What will you be doing this semester? Where is the technology? The user interface was once the last part of a system to be designed. Now it is the first. It is recognized as being primary because, to novices and professionals alike, what is presented to ones senses is ones computer. Kay, A. (1984). Computer software. Scientific American, 251(3), 41-47. HCI mattersIn general, interfaces are a very large part of effort of systemFinancial impactMake or breakCreating good user experiences with systems is hard achieveLesson 1: You cannot rely on intuitionLesson 2: HCI techniques can really helpLesson 3: Hard work, using established techniques, is the secret (not brilliant insight by the gifted lazy)What is involved in the process of interaction design While not done well enough:Understand usersEstablish requirementsBrainstorm alternatives creativelyPrototyping alternativeEvaluate theseReflect on strengths and weaknesses of prototypes

44Well enough?Assess the user experience:Minimally assess usabilityeffectiveness, efficiency and satisfaction with which specified users achieve specified goals in particular environments.
