Abstract | Smart glasses equipped with eye tracking technology could be utilized to develop natural interaction techniques. They could be used to conveniently interact with an electronic appliance in the environment from a distance. We describe a technique, HeadTurn, that allows a user to look at a device and then control it by turning the head to the left or right. We evaluated HeadTurn using an interface that linked head turning to increasing or decreasing of a number shown on a display. The task was to adjust then number to a given value. We studied the optimal rate at which number should change once the angle of head turn exceed a predefined threshold. We varied the rate of change of the number (217, 290, and 435ms per change) and the feedback (visual, haptic+visual). In the haptic condition, a 20 millisecond vibration was given through vibrating eye glass frame with each number change. Participants completed number selections faster with shorter intervals but also overshot the target more often. Seven out of 12 participants preferred the middle number changing speed (i.e., 290 ms). There were no statistically significant differences in task completion times. The optimal change rate of the numbers seems to be a compromise between faster selection and overshooting. Haptic feedback made the interaction slightly faster but the difference was not significant. The participants rated their experience with the technique as positive in general. |

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.
