This presentation outlines the findings of two surveys that were conducted throughout Europe by two FP7 projects (ÆGIS and ACCESSIBLE), addressing the specific needs for AT ICT (Assistive Technologies for ICT applications) and accessibility in the area of desktop, web and mobile accessibility, while also understanding the needs of the developing community with regards to assessment and simulation tools to enable them in ensuring their developed applications are accessible to an as wide as possible audience. Based on the collected data, a large number of commonalities were pinpointed across all targeted user groups in all countries where the survey was conducted. As a next step to support a fully user centred design within the projects, a whole range of personas were defined, depicting people with disabilities in a variety of (working) environments. The presented findings are at present being used for the development of open source assistive technologies, development, assessment and simulation tools to support accessibility for desktop, mobile, web and rich internet applications.
