| Abstract | Though tactile maps have been shown to be useful tools for visually impaired individuals, their availability has been limited by manufacturing and design costs. In this paper, we present a system that uses 3D printing to (1) make tactile maps more affordable to produce, (2) allow visually impaired individuals to independently design and customize maps, and (3) provide interactivity using widely available mobile devices. Our system consists of three parts: a web interface, a modeling algorithm, and an interactive touchscreen application. Our web interface, hosted at www.tactilemaps.net, allows visually impaired individuals to create maps of any location on the globe while specifying (1) what features to map, (2) how the features should be represented by textures, and (3) where to place markers and labels. Our modeling algorithm accommodates user specifications to create map models with (1) multiple layers of continuously varying textures and (2) markers of various geometric shapes or braille characters. Our interactive application uses a novel approach to 3D printing tactile maps using conductive filament to provide touchscreen overlays that allow users to dynamically interact with the maps on a wide range of mobile devices. This paper details the implementation of our system. We also present findings from a user study validating the usability of our mapping interface and the utility of the maps produced. Finally, we discuss the limitations of our current implementation and the plans we have to improve our system based on feedback from our user study and additional interviews. |

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.
