| Abstract | Spatial hypertext is an effective medium for the delivery of help and instructional information on the Web. Spatial hypertext's intrinsic features allow documents to visually reflect the inherent structure of the information space and represent implicit relationships between information objects. This work presents a study of the effectiveness of spatial hypertext as medium for delivery of instructional information. Results were gathered based on direct observation of the people reading a spatial hypertext document which was used as informational support for a complex task. Two versions of the spatial hypertext document were used: a non-adaptive and an adaptive. The document was adapted based upon the inferred relevance of information to the user's knowledge and task requirements. The study produced insights on emergent reading strategies such as informed link traversals and the use of collections as bookmarks. Observations and evaluation of how people interacted with both document versions showed that the spatial layout and the use of collections as a way to encapsulate information allowed people to read browse and navigate very large information spaces while maintaining a clear understanding the structure of the information. Finally several differences between the adaptive and non-adaptive versions were identified showing that adaptation alters not only the display of information but the way that people read spatial hypertext document. |

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.
