"Press On provides the insights, concepts, and programming tools to improve usability. Knowing the computer science is fundamental, but Press On also shows how essential it is to have the right approaches to manage the design of systems that people use. Particularly for complex systems, the social, psychological, and ethical concerns - the wider design issues - are crucial, and these are covered in depth." "Press On highlights key principles throughout the text and provides cross-topic linkages between chapters and suggestions for further reading. Additional material, including all the program code used in the book, is available on an interactive web site. Press On is an essential textbook and reference for computer science students, programmers, and anyone interested in the design of interactive technologies."--BOOK JACKET.
