| Abstract | It is important to understand the mechanism to integrate visual and other information for the perception of gravitational vertical under different conditions of gravity, although most of the experiments to investigate the topic reported so far has been carried out under normal-gravity (1 G) and under micro-gravity produced in short duration of parabolic flight. The purpose of this research is to investigate human perception of gravitational vertical under hyper-gravity (1.5G and 2G) to compare that under normal-gravity (1 G). We measured perceived gravitational vertical using a visual probe presented at the center while manipulating the orientation of visual stimuli (scenery picture) presented in the surround and the magnitude of gravitational acceleration. The environment of hyper-gravity was produced by centrifugal force of a rotating flight simulator. The results show that the accuracy of perceived gravitational vertical increased and the precision of it decreased under hyper-gravity condition relative to those under the normal-gravity condition when no visual stimulus was presented. However, the effect of the tilt of visual stimuli did not change under different gravity conditions. |

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.
