Previous research has indicated that continuous rotation of geographic terrain between two- and three-dimensional (2D and 3D) views aided task switching. However, continuous rotation may have provided a preview of terrain not available in the control condition. To test this possibility, we made the preview time equal. Twenty-four participants made judgments about the properties of two points placed on 2D or 3D displays of terrain. Participants performed the tasks in pairs of trials, switching tasks and displays between trials. In the continuous transition condition, the display rotated in depth and in azimuth from one display format to the other. In the discrete transition condition, the azimuth rotation was in the opposite direction, and then the terrain “snapped” to the final orientation. Response time after transition was less for the continuous condition. We argue that continuous transition to the correct position provided improved visual momentum between displays.
