This app-design book is focused on generic mobile interface and interaction creation, rather than a specific platform or device form factor. The examples are provided in both Android and iOS, but the tips and techniques apply to developers of Blackberry OS or Windows Phone too. The book allows development students to prepare themselves for creating better apps by providing them with the mindset and vocabulary of interaction design. With the help of this book, students will feel more comfortable about making successful interface design decisions, and then delve right in. A companion website provides a variety of valuable assets, including referenced Photoshop files and hyperlinks to various tools mentioned throughout the book.
