| Abstract | Teleoperated robots are used in a variety of applications. The immersive nature of the teleoperated experience is often limited by a lack of haptic information. However, in many applications there are difficulties conveying force information due to limitations in hardware fidelity and the inherent tradeoffs between stability and transparency. In situations where force feedback is limited, it is possible to use sensory substitution methods to convey this force information via other sensory modalities. We hypothesize that skin stretch feedback is a useful substitute for kinesthetic force feedback in force-sensitive teleoperated tasks. We created and tested a tactile device that emulates the natural skin deformation present during tool mediated manual interaction. With this device, experiment participants performed teleoperated palpation to determine the orientation of a stiff region in a surrounding artificial tissue using skin stretch, force, reduced gain force, graphic, or vibration feedback. Participants using skin stretch feedback were able to determine the orientation of the region as accurately as when using force feedback and significantly better than when using vibration feedback, but also exhibited higher interaction forces. Thus, skin stretch feedback may be useful in scenarios where force feedback is reduced or infeasible. |

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.
