Over twenty-five years of research and practice in the human-computer interaction (HCI) field are relvant to oohci methods.

These pages start to summarize oohci-relevant research and practice:

• Cognitive engineering forms the basis for oohci methods
• Cognitive models are the primary output of cognitive engineering-based approaches
• The basic steps needed to adopt a cognitive engineering approach
• Verification by uesrs ensures that we design useful and usable systems
• Topics for pages under construction

Introductory HCI material is also discussed, at greater length, in Chapter 10 of Object Modelling and User Interface Design: Designing Interactive Systems.
