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 co...

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. Fr...

It has support for UTF-8 unicode encoding. The system allows users to train it and personalize and as per their writing style into different named domains. Hence, it adapts to user's writing style in some sense. Although, the current version does not support live mode adaptation, still a user can train a domain as many times he likes. Anumaan is designed for a (text) sequence prediction based on a certain Context.The context can either be a partial word context or a partial sentence context. Therefore, it is intended to help people suffering from different kinds of motor disability by...
