| Abstract | Co-located work environments allow people to maintain awareness by observing others' actions (called consequen-tial communication), but the computerization of many tasks has dramatically reduced the observability of work actions. The recent interest in gestural interaction techniques offers the possibility of recreating some of the noticeability of previous work actions, but little is known about the observability and identifiability of command gestures. To investigate these basic issues, we carried out a study that asked people to observe and identify different sizes and morphologies of gestures from different locations, while carrying out an attention-demanding primary task. We studied small (tablet sized), medium (monitor-sized), and large (full-arm) gestures. Our study showed that although size did have significant effects, as expected, even small gestures were highly noticeable (rates above 75%) and identifiable (rates above 69%). Our results provide empirical guidance about the ways that gesture size, morphology, and location affect observation, and show that gestural interaction has potential for improving group awareness in co-located environments. |

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.
