| Abstract | We propose an embodied interface that allows both physical and virtual displacement within an Immersive Virtual Environment (IVE). It consists of a modular wearable used to control a mechanical motion base from which a user is suspended. The motion base is able to navigate in 3D through seven wires whose length is adjusted via a parallel link manipulator. Furthermore, an IMU-based body posture detection enables users to "fly" within the IVE at their own will, providing hands-free navigation, and facilitating other tasks' interactions. To assess the usability of this embodied interface, we compared it with a Joystick-based navigation control. The results showed that this interface allows effective navigation towards several targets located in 3D space. Even though the efficiency of target reach of the Joystick-based interaction is higher, a subjective assessment shows that the interface is comparable to the Joystick in hedonic qualities and attractiveness. Further analysis showed that with more practice, participants might navigate with a performance comparable with the Joystick. Finally, we analyzed the embodied behavior during 3D space navigation. This sheds light on requirements for further 3D navigation design. |

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.
