This preface tells the story of how Multimodal Usability responds to a special challenge. Chapter 1 describes the goals and structure of this book. The idea of describing how to make multimodal computer systems usable arose in the European Network of Excellence SIMILAR - "Taskforce for cre- ing human-machine interfaces SIMILAR to human-human communication," 2003- 2007, www. similar. cc. SIMILAR brought together people from multimodal signal processing and usability with the aim of creating enabling technologies for new kinds of multimodal systems and demonstrating results in research...

This book will present significant projects and studies carried out in academia and in industry seeking to develop new mobile multimedia systems that go beyond mobile TV (in terms of purely media streaming) and are more enjoyable and relevant for the nomadic and peripatetic user. To do this, it will showcase successful methodologies and new relevant solutions that extend the field of action of people on the move, improving, at the same time, the quality of their mobile experience.

The objectectives of the book are as follows:

• to gain insight into the future of mobile...

An increasing number of systems are exploiting mixed reality but to date there are no systematic methods, techniques or guidelines for the development of such systems. In bringing together contributions on a broad range of mixed reality development issues this book provides a sound theoretical foundation for a disciplined approach to mixed reality engineering.

Divided into three parts: interaction design, software design and implementation, the first section covers generic and specific mixed reality design elements and provides an overview of the design method; Part 2 addresses...
