Abstract：Objective To explore the characteristics of orientation task in three-dimensional space and discuss the differences in the performance of orientation tasks inside simulated visual weightless environment under various orientations.Methods Sixteen male subjects were selected to participate in the intra-vehicular orientation tasks,and the differences in the performance of intra-vehicular orientation tasks under various body-orientation conditions were tested.In addition,the spatial ability of these subjects was also tested and correlation between the performance of the subjects in spatial ability tests and their performance in intra-vehicular orientation tasks were evaluated.Results The performance under different body-orientation conditions varied significantly,and with the body-orientation deviating more from the prototypical orientation,more reaction time was needed for the orientation task.The spatial ability test performances were correlated significantly with the performance in intra-vehicular orientation tasks.Conclusion "Orientation dependence" effect existed in the three-dimensional orientation tasks,and it is essential to provide multi body-orientation preflight training for astronauts to complete the orientation task on-orbit effectively and the individual spatial ability may play an important role in intra-vehicular orientation tasks.
