| Abstract | In preceding research, the concept of the Hand Motion Language (HML) was developed as a novel and intuitive interface for Computer Aided Conceptual Design (CACD) systems. Also, a pilot implementation of the HML interpreter was developed and tested. Current research focuses on the applicability of HML in real-life situations. Firstly, this paper reports on the connection of the HML to the Vague Discrete Interval Modeler (VDIM) as an input interface. Together with the HML interpreter, it serves as a testing environment. Secondly, the paper concentrates on the design and evaluation of an experiment which was done to study the quality of shape definition by hand motions. Three quality measures were established: (i) fidelity of the generated surfaces, (ii) accuracy of the surface manipulation functions, and (iii) difficulty of modeling. Fidelity is the degree to which the representation of a shape is similar to an ideal shape. Accuracy is defined as the degree of conformity of an indicated value, such as width or angle, to an ideal value. With regards to complexity, it is interesting for us how the number of geometric HML words relates to the number of manipulative HML words that has to be issued to model a given shape. A pilot study was designed and performed to gain insight into the problems when generating surfaces by hand motions. The task given to the users was completed within a few steps; however, the quality of the surfaces has to be improved. |

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.
