Abstract | Extracting patterns from large amounts of spatio-temporal data is a challenging yet important area of active study. To address this problem we have developed a visualization system that collects and intuitively displays both the gathering and moving tendencies of people in a closed environment. Two distinct graphics techniques were applied to data collected using RFID technology. The system uses time-weighted area sampling for highlighting popular areas of the information space which is combined with CIELAB color-coding for depicting directional patterns within the data. A series of usability tests were conducted to evaluate the efficiency of the proposed system as an analytic tool for the user. The experimental results demonstrate the system's effectiveness in identifying valuable patterns within a vast collection of spatio-temporal data. This visualization technique is applicable to a wide variety of data pertaining to both space and time. |

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.
