Abstract | Haptic tactile feedback is a widely used and effective technique in virtual reality applications. When an object's surface is explored by stroking it using fingers, finger nails, or a tool, a vibration response is sensed. The vibrations convey information about the surface finish and patterns in the surface structure, and they may help identify the surface. We study characteristics of real-world physical objects that are based on actual measurements. We propose novel techniques for modeling haptic vibration textures using digital filters that can simulate both stochastic and patterned textures of objects. Modeling is based on a spatial distribution of infinite-impulse-response filters that operate in the time domain. We match the impulse response of the filters to acceleration profiles that are obtained from scanning of real-world objects. The results show that our modeling is efficient in representing varying roughness characteristics of both regular-patterned and stochastic surfaces unlike prior methods that are based on a parametric decaying sinusoidal model. Our experiments employ an existing handheld mobile scanning setup with a visually tracked probe, which provides acceleration and force profiles. Our simple capturing devices also remove any need for a robotic manipulator. |

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.
