The 7th IFIP Workshop on Software Technologies for Future Embedded and Ubiquitous Systems (SEUS) followed on the success of six previous editions in Capri, Italy (2008), Santorini, Greece (2007), Gyeongju, Korea (2006), Seattle, USA (2005), Vienna, Austria (2004), and Hokodate, Japan (2003), establishing SEUS as one of the emerging workshops in the ?eld of embedded and ubiq- tous systems. SEUS 2009 continued the tradition of fostering cross-community scienti?c excellence and establishing strong links between researchand industry. The ?elds of both embedded computing and ubiquitous systems have seen considerable growth over the past few years. Given the advances in these ?elds, and also those in the areas of distributed computing, sensor networks, midd- ware, etc. , the area of ubiquitous embedded computing is now being envisioned as the wayof the future. The systems and technologies that will arise in support of ubiquitous embedded computing will undoubtedly need to address a variety of issues, including dependability, real-time, humanβcomputer interaction, - tonomy, resource constraints, etc. All of these requirements pose a challenge to the research community. The purpose of SEUS 2009 was to bring together - searchersand practitioners with an interest in advancing the state of the artand the state of practice in this emerging ?eld, with the hope of fostering new ideas, collaborations and technologies. SEUS 2009 would not have been possible without the e?ort of many people.
