HCI is the study and planned design of human and
computer activities. HCI uses productivity, safety
and entertainment to support and fulfill humancomputer
activities and is applied to various types of
computer systems, including air traffic control,
nuclear processing, offices and computer gaming

How does knowledge inform design?
– Simon’s Sciences of the Artificial
• How can I use knowledge in my design practice?
– Schön’s Reflective Practice
• How is technology design special?
– Arthur’s Nature of Technology: What it is and how it evolves.
• How do we design interaction of technology with people?
– Norman’s Cognitive Engineering
• How do we build the knowledge we need to do all this?
– Bloom’s Taxonomy of Educational Objectives
– Perry’s Scheme of Intellectual and Ethical Development

Goal: design knowledge and capabilities that will
develop with experience
• Process: apprenticeship with experienced designer
– Design projects, some quite abstract
– Design reviews by expert
– Knowledge of materials & media
• Developed for static media (e.g. architecture->
buildings, industrial design -> products)
• The core of most BAA/MAA programs

Designer is not the star – best design is invisible
• Goal is not appreciation of designers, reviews from
bloggers or tech writers
• Goal is to make your user “feel like a hero!”
• Business management has “servant leaders”, SIAT
HCI should train “servant designers” for applications
where overall performance is critical
• IAT201 focus is on cognitive performance of users
