| Abstract | Smart spaces aim at providing personalized services to their inhabitants. This implies that the smart space has to be aware of who their users are, ideally through a seamless, informative and effortless procedure that should be integrated in the normal interaction model with the space. In this direction, this paper presents a method to naturally identify the user through his gestures in a smart environment. The system uses a Kinect sensor and relies on a supervised Dynamic Time Warping algorithm to process the position of the center of the user's hand palm. In our tests, the system is able to identify with up to 30 gestures, which include directional and geometric movements (10) and small and capital letters (10-10). Results with 11 users and leave-one-out cross validation show that the system satisfactorily works when the user concatenates two gestures (letter-movement like compositions), providing an average correct classification rate (CCR) of 95.5% when the user freely chooses the gesture sentence. CCR may be up to 100% if the system itself proposes the identification sentence, including pairs of gestures that contain more “personal features” about the user. |

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.
