Like any good interactive design, a specific scope has been kept in mind from the very beginning -- if this book was all things to all people, it would be much larger or we'd simply never have finished it. Our focus here has been on design. By which we mean information architecture, information-, interaction-, interface-, and visual design, and copywriters.

If your job title, job description or deliverables have names like those, and you work in mobile, then you need this book. If you are moving from another field, such as mobile design, or are switching from one narrowly focused mobile area to another, this book encompasses general patterns that HELP>>>

If you work in a related job, there is still something for you. Human factors engineers and HCI experts will find numerous discussions of why these solutions have become patterns, and references to cognitive psychology and physiology reasons these are true.

Development is not addressed as such, but the book has been organized so it can be used to find specific solutions to any mobile interaction. If you don't have a dedicated design team, you can use the patterns to find and focus on solutions, confirm they are technically possible, and to avoid common implementation pitfalls.

SOMETHING>>>> Even if you have been doing the job for years, it changes all the time,

Ideally, hardware designers also.

But they never will, so anyone who designs for mobiles of any sort. Full of design patterns for the interactive space, but also hardware hints and related topics.

Which are there because often to make the best, most contextually-relevant user interface, you need to understand glare and reflectivity and the impact of buttons being in different places...
