| Abstract | We present insights from a gesture elicitation study in the context of interacting with TV, during which 18 participants contributed and rated the execution difficulty and recall likeliness of free-hand gestures for 21 distinct TV tasks. Our study complements previous work on gesture interaction design for the TV set with the first exploration of fine-grained resolution 3-D finger movements and hand pose gestures. We report lower agreement rates (.20) than previous gesture studies and 72.8% recall rate and 15.8% false positive recall, results that are explained by the complexity and variability of unconstrained finger gestures. Nevertheless, we report a large 82% preference for gesture commands versus TV remote controls. We also confirm previous findings, such as people's preferences for related gestures for dichotomous tasks, and we report low agreement rates for abstract tasks, such as "open browser" or "show channels list" in our specific TV scenario. In the end, we contribute a set of design guidelines for practitioners interested in free-hand finger and hand pose gestures for interactive TV scenarios, and we release a dataset of 378 Leap Motion gesture records consisting in finger position, direction, and velocity coordinates for further studies in the community. We see this exploration as a first step toward designing low-effort high-resolution finger gestures and hand poses for lean-back interaction with the TV set. |

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.
