Spatial reasoning in architectural design can be better understood by considering the factors that affect the spatial updating process of the individual in an environment. This study focuses on the issue of spatial updating of viewed and imagined objects after rotational and translational body movements in a virtual environment (VE). Rotational and translational movements based on an egocentric frame of reference where there is no control of the user are compared in a desktop VE. Moreover, preference in architectural drawing medium and gender are analyzed as the factors that affect the spatial updating of objects in each body movement type. The results indicated that translational movement was more efficient than the rotational movement in judgment of relative directions in viewed objects. Furthermore, the viewed objects were more correctly spatially updated than the imagined ones both in translational and rotational body movements. In comparison of hand, computer and both as the drawing media, findings indicated that preference in computer medium in architectural design drawings was an effective one in spatial updating process in a VE. Contrary to the previous studies, it is found that there was no significant difference between gender and movement types.
