2 harmonisation of accessibility components in the context of “accessible” project
DESCRIPTION
The current presentation presents the Harmonized Methodology that has been developed in the context of ACCESSIBLE project in order to link critical accessibility components. ACCESSIBLE “Accessibility Assessment Simulation Environment for New Applications Design and Development” is a three year STREP Project of the 7th EU Framework Programme for Research and Technological Development (FP7), that aims to define an overall European Assessment Simulation Environment making extensive use of the latest available IT technologies and concepts. Upon the basis of an overall harmonized design and structure, the developed methodology will evolve all types of disabilities that are targeted in the project, the ICF classification, the interaction limitations of these disabilities, the assistive technologies used and the respective guidelines in each ACCESSIBLE area (web applications, mobile applications, web services and Description languages) and will correlate them in such a way that any user can navigate among them in an easy and seamless way.TRANSCRIPT

FOSS-AMASatellite event HAM Components
Disabilities◦ There are as yet no universally accepted
categorizations of disability, despite efforts towards that goal.
◦ HAM is based on the disabilities that W3C has proposed, but we also have enhanced the aforementioned list.
◦ The disabilities are categorized according to the Main type (impairment) that they belong to.

Interaction limitations mapping◦ Based upon an adaptation of the “Barrier
Walkthrough” methodology.◦ Focus on the barriers instead of the accessibility
principles. A barrier is any condition that hinders the user's progress
towards achievement of a goal, when the user is a disabled person.
Identification of all possible barriers.◦ Explanation of the functional limitations that derive
from each disability type and sub-type. ◦ Presentation of the points that should be checked in
order to cover all possible dysfunctions of a disability type.
