Universal Access in Ambient Intelligence Environments 
9th ERCIM Workshop on User Interfaces for All, Konigswinter, Germany, September 27-28, 2006, Revised Papers

Since its establishment in 1995, the ERCIM Working Group "User Interfaces for 1 All" (WG UI4ALL) has systematically promoted the proactive realization of the design for all principles in HCI. Its activities have included the organization of a se- 2 ries of very successful workshops that have contributed to consolidate recent work and stimulate further discussion on the state of the art in user interfaces for all and its increasing range of applications in the upcoming Information Society. Such wo- shops have brought together, in a new scientific community, researchers and teams working not only in the different ERCIM organizations, but also in organizations beyond ERCIM and the European boundaries, who share common interests and as- rations and contribute to the endeavors towards making the Information Society equally accessible to all citizens. This volume contains the proceedings of the last ERCIM "User Interfaces for All" Workshop. The work of the ERCIM WG UI4ALL led in 2001 to the establishment of the – ternational Conference on Universal Access in Human-Computer Interaction 3 (UAHCI) , which takes place in the context of the HCI International Conference se- 4 ries . UAHCI has established an international forum for the dissemination and – change of scientific information on theoretical, methodological and empirical research that addresses all issues related to the attainment of universal access in the devel- ment of interactive software, attracting participants from a broad range of disciplines and fields of expertise.
