Computer Training Program for Visually Challenged at CDAC, Kharghar, Navi Mumbai during July 23–August 4, 2012

About training:
In India, about 7-8 million people are suffering from full or partial visual impairment. Such people have to be provided with different kinds of support devices to access the world and to perform routine tasks like bill payments, banking transactions, reservations etc.. Now technology, either software-based or hardware-based, has made it possible for these people to access the world in their own way. But a large section of blind population is still away from advantages of modern assistive technologies. The main reasons for this gap are not only the lack of awareness about assistive technologies available and lack of hands-on practice to use it, but also the cost of technology. Free & Open Source Software (FOSS) tools/techniques play an important role in creating assistive technologies that are free-of-cost, available to all and easily maintainable for a large portion of population in a country like India. For visually challenged people, available computer based assistive technologies include screen magnifier, screen reader, braille display, digital book reader and many more. From all of these, screen reader is the most popular and potentially useful for such people to access the computer. A screen reader is a software application that just not reads the screen from top to bottom but also helps the user to navigate the interface by communicating the current position where s/he is, where to go next by giving appropriate feedback. This training program is intended to provide a learning platform for visually challenged persons to learn the basics of computer and the usage of screen reader. The training will include using desktop, text editor, command line, word processor, spreadsheet, playing multimedia, Internet browsing and mail client. Working of screen reader with other Indian languages will also be covered during the training program. More details about training program can be found at CDAC, Mumbai website ( The GNU/Linux distribution for Visually Challenged developed by CDAC, Mumbai and FOSS based screen reader Orca will be used for training purposes.
Objectives of training program:
  • To create awareness about computer based assistive technologies available for visually challenged users.
  • To give hands-on training for basics of computer using screen reader.

Target Audience:

Visually challenged users having basic understanding of English and interest to learn new technologies.

National Workshop on FOSS Desktop Accessibility on August 26, 2011 at CDAC, Kharghar, Navi Mumbai

In today’s world, the use of information and communication technologies (ICT) is growing day by day. We use these technologies very extensively in fulfilling our routine tasks like bill payments, banking transactions, reservations and many more to the extent that ICT is not a luxury, but necessity today. A large section of the society comprising people with disabilities finds it difficult to use ICT in the same way as normal people do. This includes the visually impaired (fully or partially blind), hearing impaired, people with cognitive disabilities (memory loss, etc.) and cerebral problems etc..

Such people have to be provided with different kinds of assistive technologies either software-based or hardware-based to make ICT accessible to them. A large number of software-based assistive technologies are normally in the form of applications running on desktops which make common desktop applications (office applications, browser etc.) accessible for the disabled person. Free & Open Source Software (FOSS) tools/techniques play an important role in creating assistive technologies that are free-of-cost, available to all, easily maintainable etc. for a large portion of population in a country like India.

The workshop intends to provide a platform for promotion and adoption of FOSS in the area of accessibility as well as creating opportunities for all stakeholders to discuss and identify the areas of accessibility that are still untouched. The workshop will host keynote and invited lectures by distinguished personalities of the field.

This workshop is being organized by CDAC, Mumbai at their Kharghar, Navi Mumbai campus. More details about the workshop can be accessed at
