| Abstract | Eye gaze tracking provides a natural and fast method of interacting with computers. Many click alternatives have been proposed so far, each with their own merits and drawbacks. We focus on the most natural selection method, i.e. the dwell, with which a user can select an on-screen object by just gazing at it for a pre-defined dwell time. We have looked at three design parameters of the dwell click alternative, namely dwell time, button size and placement of content. Two experiments, with similar user interfaces, were designed and conducted with 21 and 15 participants, respectively. Different combinations of dwell times and button sizes were tested in each experiment for each participant. One experiment had content placed on the buttons to be gazed at, while the other had content placed above the buttons. One important finding is that moving the content outside the clickable areas avoids accidental clicking, i.e. the Midas Touch problem. In such a design, a combination of big buttons and short dwell times are most suited for maximizing accuracy and ease of use, due to a phenomenon identified as the 'gaze-hold' problem. |

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.
