Demographic trends and increasing support costs means that good design for older and disabled
people is an economic necessity  as well as a moral imperative. Alan Newell has been described
as a visionary who stretches the imagination of all of us and truly ahead of his time. This
monograph describes research ranging from developing communication systems for non-speaking and
hearing-impaired people to technology to support older people  and addresses the particular
challenges older people have with much modern technology. Alan recounts the insights gained
from this research journey  and recommends a philosophy  and design practices  to reduce the
Digital Divide between users of information technology and those who are excluded by the poor
design of many current systems. How to create and lead interdisciplinary teams  and the
practical and ethical challenges of working in clinically related fields are discussed. The
concepts of Ordinary and Extra-ordinary HCI  User Sensitive Inclusive Design   and Design for
Dynamic Diversity  and the use of Creative Design techniques are suggested as extensions of
User Centered and Universal Design. Also described are the use of professional theatre and
other methods for raising designers' awareness of the challenges faced by older and disabled
people  ways of engaging with these groups  and of ascertaining what they want rather than just
what they need. This monograph will give all Human Computer Interaction (HCI) practitioners and
designers of both mainstream and specialized IT equipment much food for thought. Table of
