To make better interactive technology …. We need to• Know about how people interact with things• Know about what people can and can’t do• Know about the situations in which people do things• Know about the basics of good design• Understand people’s goals

We can’t all be designers..

But we can all learn things about people and design that will help us create better stuff than we would otherwise have done…

…so our mantra for this course is….

I can design better stuff
