Technology is meant to make life easier and to raise its quality. Our interaction with technology should be designed according to human needs instead of us being required to adapt to technology. Even so, technology may change quickly and people and their habits change slowly. With the aim of supporting user acceptance of iTV, the focus of this book is on the usability of iTV applications. A method for developing interaction design patterns especially for new technologies is presented for the first time.
The main characteristics covered in this new approach are: systematic identification of recurrent design problems; usability as a quality criterion for design solutions; integration of designers into the pattern development process including identification of designers' needs, and iterative evaluation and optimisation of patterns to encourage designers to accept and use them; usability testing to identify proven design solutions and their trade-offs; presentation of specific design guidelines.
From the reviews:
"This book provides insights into the issues related to user acceptance, and the supporting design methods for popularizing interactive television (ITV) services. . The book includes extensive reviews of contemporary research in the area, as well as the quality standards available, and provides a comprehensive knowledge base in the area of television services applicability. . The book will definitely generate interest among researchers in the area of television services. . Thus, it will also help practitioners apply the concepts and provide user-centered services dynamically." (Harekrishna Misra, ACM Computing Reviews, June, 2011)
Tibor Kunert, PhD, has worked in the field of Human-Computer Interaction (HCI) for the last 10 years. At the Technical University of Ilmenau, Germany, he focussed his research work on HCI for interactive media like interactive television. He managed several research and development projects with public and private television broadcasters.
He taught and supervised numerous master students on HCI and usability engineering methods and practices, for example for television, web applications and in-car information systems. Dr. Kunert is the author of 18 scientific papers and an invited conference speaker
He earned a PhD from the Faculty of Electrical Engineering and Information Technology at the Technical University of Ilmenau, Germany. Presently he is working as HCI expert at Siemens AG in several international projects.

Dateiformat: PDFKopierschutz: Wasserzeichen-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat PDF zeigt auf jeder Hardware eine Buchseite stets identisch an. Daher ist eine PDF auch für ein komplexes Layout geeignet, wie es bei Lehr- und Fachbüchern verwendet wird (Bilder, Tabellen, Spalten, Fußnoten). Bei kleinen Displays von E-Readern oder Smartphones sind PDF leider eher nervig, weil zu viel Scrollen notwendig ist. Mit Wasserzeichen-DRM wird hier ein „weicher” Kopierschutz verwendet. Daher ist technisch zwar alles möglich – sogar eine unzulässige Weitergabe. Aber an sichtbaren und unsichtbaren Stellen wird der Käufer des E-Books als Wasserzeichen hinterlegt, sodass im Falle eines Missbrauchs die Spur zurückverfolgt werden kann.
