| Abstract | Mobile audio augmented reality systems (MAARS) simulate virtual audio sources in a physical space via headphones. While 20 years ago, these required expensive sensing and rendering equipment, the necessary technology has become widely available. Smartphones have become capable to run high-fidelity spatial audio rendering algorithms, and modern sensors can provide rich data to the rendering process. Combined, these constitute an inexpensive, powerful platform for audio augmented reality. We evaluated the practical limitations of currently available off-the-shelf hardware using a voice sample in a lab experiment. State of the art motion sensors provide multiple degrees of freedom, including pitch and roll angles instead of yaw only. Since our rendering algorithm is also capable of including this richer sensor data in terms of source elevation, we also measured its impact on sound localization. Results show that mobile audio augmented reality systems achieve the same horizontal resolution as stationary systems. We found that including pitch and roll angles did not significantly improve the users' localization performance. |

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.
