| Abstract | We are developing a new multifunctional prosthetic hand mechanism that will be interfaced to the user using a four site myoelectric (EMG) controller based on fuzzy-logic techniques. Three to four independent EMG sites (the maximum number that could be isolated without the cross-talk becoming unacceptable) are used to control three or four degrees-of-freedom (DOF) in the prosthetic hand. Fuzzy logic techniques are used to detect EMG onset and classify user intent. Membership functions for each EMG channel are based on EMG signals acquired during a training session. Standard clinical techniques are used to locate the four sites. Rules recognizing the different EMG levels associated with a particular function are automatically generated based on the recorded EMG training data. Results of experiments comparing this controller with other control algorithms used in prosthetics control are presented. As currently implemented this controller is capable of providing seamless sequential control i.e. sequential control without the intermediate switching steps with an update rate of 50 msec. |

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.
