| Abstract | In this paper we study the human eye movement, when the eye shifts its gaze between two possible gaze directions, as a simple mechanical control system. When the head is restrained to remain fixed, eye movements obey Listing's constraint, which states that the allowed orientations of the eye are obtained by rotating a fixed ‘primary gaze direction’ by a subclass of rotation matrices. These rotation matrices have their axes of rotation restricted to a fixed plane perpendicular to the primary gaze direction. Under head fixed restriction, eye movement satisfies the Listing's constraint throughout its entire trajectory. On the other hand, when the head is allowed to move, the eye orientations satisfy the Listing's constraint only at the beginning and at the end of a trajectory. Intermediate points of the trajectory, do not satisfy the Listing's constraint. In this paper, we study the dynamic control of eye movement with or without satisfaction of the Listing's constraint. The control has been synthesized by a suitable choice of a potential function and an externally added damping term. |

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.
