| Abstract | While the usability of voice-based Web navigation has been steadily improving, it is still not as easy for users with visual impairments as it is for sighted users. One reason is that sequential voice representation can only convey a limited amount of information at a time. Another challenge comes from the fact that current voice browsers omit various visual cues such as text styles and page structures, and lack meaningful feedback about the current focus. To address these issues, we created Sasayaki, an intelligent voice-based user agent that augments the primary voice output of a voice browser with a secondary voice that whispers contextually relevant information as appropriate or in response to user requests. A prototype has been implemented as a plug-in for a voice browser. The results from a pilot study show that our Sasayaki agent is able to improve users' information search task time and their overall confidence level. We believe that our intelligent voice-based agent has great potential to enrich the Web browsing experiences of users with visual impairments. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
