| Abstract | For today's computer users, the mouse plays such an important role that it dominates the interaction interface in personal computer for nearly half a century since it was invented. However, the mouse is gradually unfit for the demand of modern 3D display techniques, e.g. 3D-projection or -screen, for the reason that the relevant interactions are confined in a surface. Although some new methods such as computer vision based techniques attempt to bridge the human-computer barrier, they suffer from many limitations such as ambiguity in multitargets and dependence on light. This paper presents a battery-free device called Tagball for 3D human-computer interaction via RFID tags. Tagball devises a control ball, on which N passive tags are attached, for users to generate two basic kinds of interactive commands: translation and rotation. Instead of locating N tags independently, we model the ball as a whole in a more cooperative way under the circumstance that their geometric relationships are known in advance. In addition, we consider the phase values measured by M RF antennas for these N tags as observations of the ball state. Our key innovations are the studies on motion behaviors of a group of tags by using Extended Kalman Filter, and the implementation based on purely Commercial Off-The-Shelf (COTS) RFID products. The systematical evaluation shows that Tagball traces the ball translation to 1.5cm and identifies ball orientation to 1.8° in 3D space. |

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.
