Bill Scott has always enjoyed technology (25 years). And he has always enjoyed interacting with people (even longer). It was a natural to blend the two loves together. For a long time he couldn't decide if he was a designer or an engineer. He finally gave up trying to classify himself and just decided to live in both worlds as much as possible.

This passion drove him to create one of the first successful Macintosh games, build wargaming interfaces for NATO, found and lead UX Design teams, write Ajax frameworks (OpenRico) manage user interface engineering organizations, publish design pattern libraries, and talk a lot about it.

Susan Weinschenk first used a computer in the mid-1970’s, in graduate school. “I wrote and ran my first computer program, and the printer spit out a piece of paper that said ‘JOB ABORTED’. Rather than being discouraged I was fascinated! What would happen when ‘normal people’, not computer scientists, interact with these things called computers?” She thus started a 30-year career in applying psychology to the design of technology.

Susan has a Ph.D. in Psychology from Pennsylvania State University, and her newest book, Neuro Web Design: What makes them click?, applies the latest research on neuroscience to the design of web sites. A popular speaker and presenter, her nickname is “The Brain Lady”. She is Chief of User Experience Strategy, Americas at Human Factors International.

Caroline Jarrett was a project manager specialising in Optical Character Recognition when she landed a job in 1992 delivering OCR systems to the UK Inland Revenue for processing tax forms. The systems didn't work and she found out that it was because of the way people filled out the forms.
