This overview outlines the critical aspects of UI development, focusing on clarifying client goals, identifying issues with current systems, and defining requirements for new interfaces. The guide emphasizes user-centered design principles, requirements gathering, task analysis, prototyping, and implementation via technologies like Java and web frameworks. Evaluation methodologies including usage data, experimentation, and environmental analysis are discussed. Additionally, it touches on the historical context of HCI, cognitive psychology, and practical steps toward effective design and implementation of user interfaces.

Goals • What does the client want/need? (goal: go from vague to specific) • Representation of problems with current system • Representation of requirements of new system
Our focus is on the • Design • Implementation • Evaluation • of user interfaces …
Design… • User-centered design • principles • methods • Requirements gathering • Task analysis • Guidelines: principles and rules • Standards and Metrics • Prototyping
Implementation • Java: applet, applications • Web-based computing: • Struts • Ruby on Rails • Other??
Evaluation • Usage Data • Experiments, Benchmarking • Evaluation Methodology • Human Subjects concerns
Environment analysis • physical environment • temperature, humidity, lighting, available space • social environment • quiet/loud, busy/isolated, etc. • user support environment • helpful/hostile
Ideally …. • History of HCI, definitions • Cognitive and Perceptual Psych background • Design • Implementation • Evaluation
What we’ll do …. • History of HCI, definitions • Cognitive and Perceptual Psych background • Design • we’ll start this • go back to finish up some knowledge rep notes • skip ahead to implementation so you can start projects • go back to finish this up • Implementation • Evaluation
