Odt2braille brings braille to your office
Presented at Leipzig Braille 21.

The AEGIS project seeks to determine whether 3rd generation access techniques will provide a more accessible, more exploitable and deeply embeddable approach in mainstream ICT (desktop, rich Internet and mobile applications). This approach is developed and explored with the Open Accessibility Framework (OAF) through which aspects of the design, development and deployment of accessible mainstream ICT are addressed. The OAF provides embedded and built-in accessibility solutions, as well as toolkits for developers, for “engraving” accessibility in existing and emerging mass-market ICT-based products, thus making accessibility open, plug and play, personalised and configurable, realistic and applicable in various contexts; AEGIS is placing users and their needs at the centre of all ICT developments. Based on a holistic UCD, AEGIS identifies user needs and interaction models for several user groups, (users with visual, hearing, motion, speech and cognitive impairments as well as application developers) and develops open source-based generalised accessibility support into mainstream ICT devices/applications: desktop, rich web applications, and Java-based mobile devices.

All developments will be iteratively tested with a significant number of end users, developers and experts in 3 phases and 4 Pilot sites Europe wide (in Belgium, Spain, Sweden and the UK).

The project includes strong industrial and end user participation (the participating industries are among the market leaders in the corresponding mainstream ICT markets). The project results’ uptake is promoted by strong standardisation activities, as well as the fact that much of the technology results will be either new open source applications or will be built into existing and already widely adopted open source ICT.

Project number: 224348
Project acronym: AEGIS
Project title: Open Accessibility Everywhere: Groundwork, Infrastructure, Standards
Starting date: 1 September 2008
Duration: 42 Months
AEGIS is an Integrated Project (IP) within the ICT programme of FP7
