Humanware is everything which helps human beings to handle (use and look after) a product, e.g. controls and indicators, program ergonomy, location of assembly divisions in parts to be put together, signs and other markings, instructions, training and technical consultation. Against the background of how humans behave when handling a product, this book offers advice and explains principles for suitable design of humanware: how to analyse needs, design different types of humanware, and test that it works. A wide range of specific examples are described. Exercises after each chapter give readers the possibility of trying to solve humanware problems themselves. Suggested solutions are provided at the end of the book. The book is intended for practising developers, designers and technical communicators, and for students of these professions.
