| Abstract | This study developed a new procedure, a Virtual Guiding Avatar (VGA), which combined self-motion prediction cues and an independent visual background (IVB) to alleviate simulator sickness (SS). The VGA, which was embodied as an abstract airplane, was designed to lead the participant along a horizontal motion trajectory through a virtual environment. Both motion prediction cues and IVBs, which provide an earth-fixed reference frame, reduced SS in separate previous studies. Participants were exposed to complex visual motion through a cartoon-like simulated environment in a very wide field of view driving simulator. Participants' responses to avatars with varying motion properties - fixed, rotation only or rotation plus translation - were assessed using a within-subjects experimental design. Results indicated that SS was reduced by a VGA that presented rotational cues alone or rotation plus translation. The VGA also increased participants' sense of presence and enjoyment relative to conditions lacking a VGA. The VGA procedure can be used to enhance user experiences in immersive virtual environments as well as to improve motion simulator design. |

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.
