| Abstract | User interfaces are evaluated through techniques that require end-users and usability experts. These techniques are costly and time consuming. Therefore, quantitative techniques such as predictive metrics can be considered an indispensable alternative to address some of user interface issues. One of these metrics is a visual cohesion metric. In order to investigate the effectiveness of visual cohesion metrics as an indicator of the usability of a user interface during the early stages of user interface development, this paper introduces the Screen Layout Cohesion (SLC) metric, which is based on aesthetic, structural, and semantic aspects of GUIs. The SLC can be used to predict the usability of user interfaces in early stages of software development. This metric is supported by a complementary tool called GUIExaminer, which provides automatic calculation of the SLC metric. Our findings provide an empirical validation of the SLC for a set of user interfaces. We found that the prediction of user interface usability with the help of the SLC matches 89.7% of the results based on the participants' evaluation of the same user interfaces. |

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.
