| Abstract | There has been extensive discussion and research surrounding fidelity or refinement of prototypes in paper and software form, especially focusing on how the nature of prototypes influences the feedback that this prototype can help elicit during user testing. We extend this debate to the domain of video prototypes, where use scenarios are acted out on video. This study examines how the visual refinement (a.k.a. visual fidelity) of design representations presented in such videos impacts user feedback. An experiment was performed where two video prototypes were compared, one where the product is portrayed with high visual refinement and the other looking rough and sketchy. Our results could not identify any significant effects upon the number or type of comments returned by users. This finding contrasts widely held contentions relating to fidelity of software and paper prototypes, though it agrees with similar experiments done with non video prototypes. In practice our results support the validity of testing with low fidelity videos and suggest that the choice of visual fidelity in video prototypes should be based on pragmatic project concerns, e.g., whether the video should be used also for communication and the resources that are available for prototyping. |

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.
