| Abstract | The display cloud model allows users to select local and remote programmable displays, and add them to a user specific cloud display where the user can arrange them freely. On a cloud display, the abstraction representing remote graphical content is termed a visual. It can be positioned and resized freely. Wherever a visual touches a part of the cloud display with physical displays present, the physical displays will show the corresponding graphical content of the visual. The physical displays can simultaneously show several visuals from one or many users. The display cloud approach is suitable for public environments because we do not allow user customization of the displays, a user does not have to expose any data except the actual graphical content to the display computers, and he does not have to go through the displays to do user interaction with his resources. Mobile devices have an essential role in achieving this. They provide, for each user, the means to detect displays, to add displays to the user's cloud display, to manage displays and visuals in a cloud display, and to interact with visuals. An insight is that the display cloud model is maximally decentralized between users, and maximally centralized per user. We conducted a set of experiments on a prototype using 28 display computers with up to 21 users. The results show that the prototype reacts interactively fast for each, and scales well to many users. |

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.
