Since the time when interactive television emerged as a medium for the home environment, ithasbeenpermanentlyevolving.Changingrequirementsanduser behavior, e.g., the demand for being mobile and have access to information and entertainmentanywhereandanytime, arechallenginginteractiveTV.Newkinds of interactive services have to be conceived for the increasing mobile, ubiquitous requirements of the di?erent user groups. In these changing environments, a better understanding of emerging contexts and their implications is essential. This gave birth to the idea for the theme of the EuroITV 2008 Conference: "Changing Television Environments." EuroITV 2008, the 6th edition of the - ropean Conference on Interactive Television, was organized and hosted by the HCI and Usability Unit, ICT&S Center, University of Salzburg, Austria. The EuroITV Conference Series started at Brighton University in 2003 and 2004. It was followed by Aalborg University in 2005, Athens University of Economics and Business in 2006 and by CWI (Centrum Voor Wiskunde en Informatica) in Amsterdam 2007. We would like to thank all former Chairs for making this greatconference series happen andfor providing us with the opportunity to host EuroITV 2008.

Most of our everyday life experiences are multisensory in nature; that is, they consist of what we see, hear, feel, taste, smell, and much more. Almost any experience you can think of, such as eating a meal or going to the cinema, involves a magnificent sensory world. In recent years, many of these experiences have been increasingly transformed and capitalised on through advancements that adapt the world around us - through technology, products, and services - to suit our ever more computerised environment. Multisensory Experiences: Where the senses meet technology looks at this trend and offers a comprehensive introduction to the dynamic world of multisensory experiences and design. It takes the reader from the fundamentals of multisensory experiences, through the relationship between the senses and technology, to finally what the future of those experiences may look like, and our responsibility in it. This book empowers you to shape your own and other people's experiences by considering the multisensory worlds that we live in through a journey that marries science and practice. It also shows how we can take advantage of the senses and how they shape our experiences through intelligent technological design.

Nowadays, the Internet has opened up new opportunities to share innovations and to collaboratively innovate and modify products and especially software as shown in the open source software movement. Industry and designers have already started to react on this development by supporting end-user involvement in the design and development process. Still the user potential for being innovative themselves is underestimated. This book is aiming to fill parts of this gap by investigating user modifications in the home context, while emphasising how and why users modify interactive systems. A detailed view on recent trends and interdisciplinary theories on user driven modifications is presented and a new approach called "Do-It-Yourself Human-Computer Interaction (DIY HCI)" is developed. This "do-it-yourself" approach allows people to modify and customize their interactive systems in a more individual and advanced way. People will always engage in areas they are interested in or when they have special needs to solve. Thus, manufacturers will have to provide users more freedom, control and transparency in the interaction with emerging systems or products.
