About This Book
Newton 2.0 User Interface Guidelines describes how to create
software products that optimize the interaction between people
and devices that use Newton 2.0 software. The book explains
the whys and hows of the Newton 2.0 interface in general terms
and in specific details.
Newton 2.0 User Interface Guidelines helps you link the philosophy
behind the Newton 2.0 interface to the actual implementation of
the interface elements. Examples from a range of Newton soft-
ware show good human interface design. These examples are
augmented by descriptions and discussions of the reasoning behind
the guidelines.
This book also contains examples of how not to design human
interface; they are marked as such and appear with a discussion
that points out what’s inappropriate and how to correct it.

Who Should Read This Book

This book is for people who design and develop software for
Newton devices. If you are a designer, a human interface
professional, or an engineer, this book contains information you
need to design and create software that fits the Newton model.
It also provides background information to help you plan your
software product’s design.
Even if you don’t design and develop software for Newton, reading
this book will help you understand the Newton interface. This
understanding is useful to managers and planners who are
thinking about developing Newton software, as well as to people
who are studying human interface design in general.
