No single person can know everything, which is why this book is a must for anyone designing a GUI (graphical user interface). Software programmers and web site designers can easily lose sight of exactly how a person will interface with their design. With no guidance or feedback from the user, bloopers are bound to abound. Author Jeff Johnson, who is a specialist in human-computer interaction, discusses mistakes that software programmers are likely to make in layout, text, interaction, responsiveness, management and more. His overall approach of designing from the outside in turns the programmer's focus to the end user. Loads of examples, both good and bad, are included.
