| Abstract | Since handheld and wearable displays are highly mobile, various applications are enabled to enrich our daily life. In addition to displaying high-fidelity information, these devices also support natural and effective user interactions by exploiting the capability of various embedded sensors. Nonetheless, the set of built-in sensors has limitations. Add-on sensor technologies, therefore, are needed. This work chooses to exploit magnetism as an additional channel of user input. The author first explains the reasons of developing the add-on magnetic field sensing technology based on neodymium magnets and the analog Hall-sensor grid. Then, the augmented input space is showcased through two instances. 1) For handheld displays, the sensor extends the object tracking capability to the near-surface 3D space by simply attaching it to the back of devices. 2) For wearable displays, the sensor enables private and rich-haptic 2D input by wearing it on user's fingernails. Limitations and possible research directions of this approach are highlighted in the end of paper. |

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.
