Need For Web Accessibility Final

  1. 1. Need for Web Accessibility in Developing Countries Yahoo! Initiatives<br />By Srinivasu ChakravarthulaAccessibility Manager<br />
  2. 2. Internet and its usage<br />Applications<br />Education Research Business <br />Travel<br />Shop Entertainment Social Networking Music Matrimony <br />Users:<br />Student, parent, teacher, professionals, government, senior citizens… and everyone!<br />
  3. 3. Users of internet also <br />includes people with <br />special needs<br />
  4. 4. Statistics…<br />
  5. 5. Some facts…<br />As per WHO, there are about 600 million people with disabilities across the world<br />In India alone, there are about 70 million<br />There is a rapid development in the area of assistive technology industry!<br />
  6. 6. Disability and types of disabilities<br />Unable to perform a particular task<br />It can be a temporary or permanent<br />Can occur either by birth or by accident<br />Situational Disability<br />Oops! My mouse stopped working <br />Text is too small on this webpage<br />Functional Disability<br />Visually impaired<br />Mobility impaired<br />Hard of hearing<br />Learning disability<br />Autism, CP<br />
  7. 7. How People with Disabilities Use Computer<br />Screen readers<br />Screen magnifiers<br />On-screen keyboard<br />Track ball<br />Switch<br />Ergonomic Keyboard<br />Refreshable Braille Display<br />
  8. 8. Web is more useful <br />to people with<br />disabilities<br />
  9. 9. Deepa Narasimhan, Graphic Designer, EMC<br />As far as I use the On screen <br />keyboard, its easy on all website. <br />Maybe we need a better voice <br />recognition software which can <br />use on computers for typing & <br />browsing websites. Which would <br />help people with sever <br />conditions, as few people with no<br />hands (amputees) will find this <br />great way to browse the internet.<br />
  10. 10. Case studies continued… Artur Ortega<br />The internet allows me as a blind person<br />to get access to services and information <br />without any help by anyone which<br />wouldn&apos;t be even be possible or very <br />difficult in a physical world. The internet<br />creates new opportunities and creates a <br />full new independency for persons with <br />disabilities.<br />I really miss the approach of a great part <br />of the private sector to embrace <br />accessibility. Only some very innovative<br />companies like Yahoo! are taking the first <br />steps to even make web 2.0 applications <br />accessible and breaking into new <br />dimensions of accessibility. I would love if <br />more and more companies would follow <br />this great example.<br />
