| Abstract | This paper investigates through experiments the performance of two recent control architectures for networked haptic cooperation [10], [11]. The two architectures can render direct haptic interaction between networked users in addition to cooperative manipulation of virtual objects. This is because both architectures employ remote dynamic proxies to represent users at their networked peer sites. The remote dynamic proxies have second order dynamics and are controlled by the distant user whom they represent via virtual coupling (i.e., power-based) control or via wave-based control. The remote dynamic proxies render smooth motion of their respective user in the presence of update discontinuities caused by limited network transmission rates and by network delays. The experimental comparison investigates the performance of cooperative manipulation and of direct user-to-user contact for various constant network delays. The results illustrate that: (1) both power-based and wave-based control of remote dynamic proxies can maintain high position coherency between the distributed copies of the shared virtual object; (2) wave-based control of remote dynamic proxies renders the inertia of the shared virtual object and of the remote dynamic proxies more realistically than virtual coupling control; and (3) wave-based control of remote dynamic proxies maintains the networked haptic cooperation stable for longer constant network delays. |

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.
