Human Computer Interaction is nothing but the interaction between computers and users. The basic goal of HCI is to improving the interaction between users and interaction systems, these interaction systems may be websites or mobiles or iPods and etc. For developing the websites the web developers must follow the w3c recommendations. According to w3c, the web accessibility means “people with disabilities can use the web” (Source: http://www.w3.org/WAI/intro/accessibility.php). Web accessibility covers all disabilities for accessing the web content. According to Disability discrimination Act the term disability refers to “someone who has a physical or mental impairment that has a substantial and long-term adverse effect on his or her ability to carry out normal day-today activities” (Source: http://www.direct.gov.uk/en/DisabledPeople/RightsAndObligations/DisabilityRights/DG_4001069). The disabilities include visual disability, cognitive disability, hearing disability and etc. From the last one and half decade web is the most useful medium for the people in various fields. So the web designers must consider the disability people also while designing the websites. Cognitive disability is the largest disability group in our community. But the cognitive disability is the least understood and least discussed type of disability. As a result, the web developers rarely design the websites accessible to the cognitive disable people. The people with cognitive may have memory problems, dyslexia, problem solving, visual comprehension and etc. so lot of research work will be going on this kind of people. In one survey it is noted that (in 2000) around 21.1% of people are suffering with visual disabilities, 27.2% of people are suffering with hearing problems and 42.2% of people are suffering with cognitive and learning disabilities. So we need to concentrate more on Cognitive disabilities. This report will typically explore some of the web accessibility issues and some of the solutions to those web accessibility problems faced by cognitive disable people. And the present area of research in human computer interaction.
WEB ACCESSIBILITY ISSUES FOR COGNITIVE DISABLED PEOPLE:
This section describes about the problems of Cognitive Disabled people while accessing the web. There are more number of Cognitive Disabilities are present but I will discuss some of the major categories of the Cognitive disabilities. We can divide the Cognitive Disabilities as: I) Clinical Cognitive disabilities: This disability includes
a) b) c) d)
Autism Down Syndrome traumatic brain injury dyscalculia (difficulty with math)
Functional Cognitive disabilities: This disability includes a) Memory b) Problem Solving c) Attention d) Math Comprehension e) Visual Comprehension f) dyslexia (difficulty reading)
We need to concentrate more on the Functional Cognitive disabilities while considering the web accessibility issues because those are directly related to concerns of web developers.
1) Different types and causes of cognitive disabilities: a) Memory: There are three types of memories and those are immediate memory (Working memory), Shortterm memory and long-term memory....
