| Abstract | Finger touch is the most natural way for human interaction with the external world. In the past five years, the great success of multi-touch trackpad on portable devices implies the big potential of multi-touch technology to be applied in vision-based human-computer interaction (HCI) systems. The implementation of multi-touch technology highly depends on accurate and fast fingertip tracking. In this paper we present a fast and robust algorithm for tracking fingertip positions in a stereovision-based 3D multi-touch interaction system. Our method first detects the hand region by a two-step strategy based on skin color filter as well as depth images. Then a geometry model is built to locate the fingertips. The accuracy and effectiveness of the fingertip tracking algorithm is examined over several video sequences with complicated backgrounds. Experimental results verify that our algorithm can reliably and accurately track the movements of fingertips in real time. The effectiveness of the fingertip tracking algorithm also reveals the capability allowing user to interact with computers through their finger movements in 3D space over a virtual thin-film-like touch surface which is set up at a certain distance away from the screen. |

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.
