| Abstract | Spatial and temporal metaphors can play an important role in making the task of programming serve problem-solving processes. Visual programming research hopes to capitalize on innate human perceptual skills to make the programming task easier by using visualization to simplify program construction at the syntactic level. Instead, we advocate that the role of visualizations, and the consequent use of spatial metaphors, is not to simplify programming per se but instead to support the problem-solving process. To that end, environments endorsing spatial metaphors should support: creating and changing external representations of the problem, and opportunistic design strategies necessary for exploring problem spaces. We discuss problems with human-computer interaction schemes arising from the use of temporal metaphors. Direct-manipulation, on the one hand, can be too direct for controlling a number of autonomous processes such as cooperating agents. The complete delegation of tasks to agents, on the other hand, can leave users entirely in the role of passive observers. We propose a new approach, called the participatory theater metaphor, which combines the advantages of human computer interaction schemes based on direction manipulation and delegation and provides users with a continuous spectrum of control over their program behaviors. |

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.
