| Abstract | Increasing numbers of everyday objects in libraries, stores and warehouses are instrumented with passive RFID tags, resulting in a ripe opportunity for gesture-based interactions with people. By a simple act of picking up and gesturing with an RFID-tagged object, users can send their opinions and sentiments about that object to the cloud. Prior work in RFID-based gesture tracking relies on multiple bulky and expensive antennas and readers to function, which incurs unacceptable infrastructure costs for large-scale ubiquitous deployment (over an entire warehouse or mall, for example) thus hindering practical adoption. In this paper, we propose Pantomime, the first RFID-based gesture recognition system that uses just a single antenna per geographical area of coverage. Our key insight is to replace the conventional multiple antenna single tag tracking framework with an equivalent multiple tag single antenna system. Through a novel tag coordination protocol and a lightweight tracking algorithm, Pantomime enables accurate gesture tracking that works for objects tagged with just two RFID tags. We implement a real-time prototype of Pantomime with commercial off-the-shelf (COTS) RFID readers and antennas. Extensive evaluations and real-world case studies in a classroom and a retail store demonstrate that Pantomime achieves comparable gesture tracking accuracy (87%) to state-of-the-art multi-antenna schemes (88%) at a minimal deployment cost. |

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.
