| Abstract | In this work, we tested 12 participants on a virtual object precision placement task while viewing a stereoscopic 3D (S3D) display. Optometric measures of binocular function were obtained, including measurements of distant and near phorias (horizontal and vertical) and distant and near horizontal fusion ranges, using standard clinical techniques. Before each of six 30-min experimental sessions, measurements of phoria and fusion ranges were repeated. All participants completed experimental sessions in which the task required precise positional and rotational alignment of a virtual object in depth, at the same location and orientation as a stationary target object. The object was controlled by participants' spatial manipulation of a wireless 6 degree-of-freedom (DOF) tangible user interface utilizing magnetic spatial tracking. Subjective discomfort was assessed using the Simulator Sickness Questionnaire (SSQ). Individual placement precision in S3D trials was significantly correlated with several of the binocular measures: viewers with larger convergent fusion ranges, larger divergent fusion ranges, larger total fusion ranges, or lower (better) stereoscopic acuity thresholds were more accurate at the task. None of the optometric measures were predictive of individual subjective discomfort, although a combined analysis with a similar previous experiment suggested that a personal history with motion sickness was related to discomfort levels from S3D viewing. The results confirm and extend previous research, suggesting that several key optometric measurements are predictive of complex manual spatial task performance on an S3D display system. |

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.
