Accessibility in Health related Virtual Learning Environments

Supporting patients and informal carers is an essential task in managing chronic diseases. Many of these diseases are either directly linked to disabilities or are age related and, thus, also strongly correlated with potential disabilities. Furthermore, as the population ages it is becoming more and more common to give an old person with a set of mild disabilities acting as informal carer of another person with some type of chronic disease. Support material and professional help can be provided through the use of an eLearning platform. These platforms are usually known as Learning Management Systems (LMS) or Virtual Learning Environments (VLE). People with disabilities, linked to physical and/or cognitive impairments can obtain an extraordinary advantage from access to eLearning but, in practice, they find important barriers when the Virtual Learning Environments (VLE) and contents are not delivered in the suitable adapted forms according to their needs and preferences. All VLEs are supported by a set of different technological layers. Those layers can interfere with the final user gaining access to such adapted resources. Conflicts with user agents, assistive technologies and the delivery format of the resources are the most common problems. The accessibility of current VLEs, a mature technology, provides an interesting case study regarding the types of problems that can be encountered by users in current web applications
