| Abstract | Blind people often seek answers to their visual questions from remote sources, however, the commonly adopted single-image, single-response model does not always guarantee enough bandwidth between users and sources. This is especially true when questions concern large sets of information, or spatial layout, e.g., where is there to sit in this area, what tools are on this work bench, or what do the buttons on this machine do? Our RegionSpeak system addresses this problem by providing an accessible way for blind users to (i) combine visual information across multiple photographs via image stitching, em (ii) quickly collect labels from the crowd for all relevant objects contained within the resulting large visual area in parallel, and (iii) then interactively explore the spatial layout of the objects that were labeled. The regions and descriptions are displayed on an accessible touchscreen interface, which allow blind users to interactively explore their spatial layout. We demonstrate that workers from Amazon Mechanical Turk are able to quickly and accurately identify relevant regions, and that asking them to describe only one region at a time results in more comprehensive descriptions of complex images. RegionSpeak can be used to explore the spatial layout of the regions identified. It also demonstrates broad potential for helping blind users to answer difficult spatial layout questions. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
