| Abstract | Virtual Acoustic Space (VAS) is a research and development project on the perception of space using only sound. A portable electronic prototype that allows blind people to receive spatial information of their surroundings has been developed. This information is perceived via an audible image using Head Related Transfer Function (HRTFs) processed sounds. The main goal is to create for the user the illusion that the surrounding objects are covered by small sound continuously emitting sources in a particular and sustained way. Therefore, a virtual acoustic world is generated, where a physical object emit sounds from all the coordinates of its surface. Our results validate the hypothesis that, it is possible to generate an experience of global and sustained presence of different objects inside the perception field from these stimuli, with the same shape, dimensions and location as the real environment. Our objectives are now focused on: a better delimitation of the observed capabilities, the study of the developed prototype in everyday life conditions, on exploring how blind people learn to use new strategies to improve their perception of the environment and the exploration of the possible cortical brain areas involved in this process, using functional imaging techniques |

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.
