| Abstract | Distance perception by hitting with a holding stick is quite important for the people with visual impairments who daily use white cane. If the mechanism of this perception is well understood, it can be applied for the development of more intuitive and simple electric white cane consisting of a range sensor and a haptic display. A hypothetical mechanical model of a stick and a holding palm told us that hitting at a closer point should induce a stronger vibration at thumb side of the palm, and percussing a farther point should induce equally distributed vibrations in the palm. To verify if this vibration distribution plays role in the distance perception, we conducted an experiment that superimpose vibration to the real vibration while percussing, to change the center of gravity of vibration. The experimental results showed that adding vibration to the thumb side shortened the perceived collision distance than adding vibration to the little-finger side, which partly agrees with our hypothetical model. |

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.
