| Abstract | In daily life, humans must compensate for the resultant force arising from interaction with the physical environment. It has been shown that humans can acquire a neural representation of the relation between motor command and movement, i.e. learn an internal model of the environment dynamics. For example, Shadmehr et al have analyzed various reaching movements under velocity-dependent force field (VF) where the hand receives the external load in proportion to the hand velocity. It is then shown that human compensates for the external load by the feedforward control based on the internal model. It is here called 〈internal model control〉. On the other hand, in manipulation tasks, such as opening a door, grasping a cup etc., the dynamic interaction between the human arm and external environment determines the stability of motion. Therefore, it has much important to adjust the arm impedance corresponding to the environment dynamics, which is called 〈impedance control〉. The talk will discuss adaptive motor behaviors to dynamic environments in human voluntary movements. The experimental results demonstrate that human adaptation to a varying dynamic environment during reaching movements is achieved by programming the internal model control and impedance control in a feedforward manner. In addition, the talk will refer to application of motor learning to physical rehabilitation. |

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.
