| Abstract | The analysis presented in this paper is the search for optimal scrolling speeds of the user interface for interactive TV (iTV) navigation. The most popular navigation techniques for browsing through user interfaces usually incorporate scrolling. Furthermore, the latest set-top-boxes have enough processing power to support very fast scrolling, not only for texts, but also for photographs and other elements. We designed and performed an experiment to measure the optimal scrolling speed for different activities on a user interface. We found that the optimal speed depends on the type and complexity of the navigational elements (like text or graphics). We discovered that less-complex elements, such as numbered TV-channel names, tolerate much higher scrolling speeds than more-complex elements, such as graphical elements like movie posters. We also analyzed the impact of the direction of navigation (vertical, horizontal) on the optimal speeds and the results show no major impact on the graphical elements, while for the text elements the difference is obvious. The results of this study can improve the usability of the horizontal and vertical navigation techniques in modern iTV navigation. |

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.
